Furthermore, knowledge of computer hardware, networking equipment and communication systems enables electronics engineering graduate and help them to annexe an edge in the IT job market.
TRACK 2: Signal Processing and Communication Engineering
Signal Processing and Communication Engineering (SPACE) have been rapidly growing and evolving over the past few years. Multimedia signal processing and Ubiquitous communication is becoming a necessity for the society. The theme of the seminar is designed to cover not only in-depth theoretical knowledge in the area of Communications, Signal Processing, and Wireless Networks, but also system modelling and integration aspects emphasising overall system behavioural studies in a laboratory. Such topics are unique and fall in-line with the requirements from the industries. At the end of the seminar the participants achieve the ability to identify pressing research issues and research directions in Communications, Signal Processing, and Wireless Networks.
TRACK 3: Information Security
With the advent of digital storage and communication technologies, the entire spectrum of storage and communication system has been revolutionised as digital information can be easily stored, copied, changed, and transported. More and more people and organisations are using digital documents instead of paper documents to conduct day-to-day transactions. These desirable properties of digital information are very useful but owing to easy and almost undetected modification of digital data, they have raised several security concerns. Therefore, digital data is regarded as unreliable in areas where privacy, authentication, and integrity of data are of concern unless some security procedure is attached to it. These are areas like contracts, receipts, approvals and others where users have severe and genuine concerns of unauthorised modification or disclosure of data. The risk of data misuse has increased many folds with the advent of networking and wireless communication as many users can gain access to the data if not secured. In recent years, the scope and dimensions of information security has evolved significantly. The area of information security besides covering security of data and information extends to security of networks and allied infrastructure. It has emerged as a profession across hardware, software and communication technologies for securing applications, apps, databases and websites; security testing; information systems auditing; business continuity planning; digital forensics and crime investigations; network, and web penetration testing; incident responding; security architecture designing; security analysis; intrusion analysis; vulnerability research; disaster recovery; etc.
Mitigating information security threats is an ongoing battle, as unique threats get prevalent swiftly, therefore, security administrators must begin with an understanding of the threats facing the information, and then must examine the vulnerabilities inherent in the systems that store, process, and transmit the information possibly subjected to those threats. Continuous identification of most serious vulnerabilities, possible threats to information and their rapid mitigation can prevent an organisation from falling prey to any such threat. Information security has been the focus of research since decades; however, with the advent of Internet and its vast growth, online information security research has become recurrent. Novel methods, techniques, protocols, and procedures are continuously developed to secure information from growing threats.

Nikon FX-format CMOS sensor with 36.3 effective megapixels
Enlarge images as big as A1 poster-sized prints (59.4 x 84.1 cm/23.4 x 33.1 in.) at 200 dpi, or crop aggressively to reach the composition you desire, all without sacrificing the detail and tonal range of the original. In order to maintain clean, high-resolution images, 14-bit A/D conversion within the sensor and a high signal-to-noise ratio deliver phenomenal images in a diverse array of situations. The image sensor's incredible potential does not stop with photography, either. For cinematographers ready to put their exceptionally sharp NIKKOR lenses into action, the D800's 36.3 effective megapixel data is efficiently processed for exquisite 1080p broadcast quality video at 30p.
Standard ISO 100 to ISO 6400, range expandable to ISO 50 to 25600 equivalent
High-resolution, studio-quality images shouldn't be restricted to the studio. The D800 set a new benchmark for high-resolution D-SLR cameras, with crisp clean images across a wide ISO range. Flexibility like this opens up new imaging opportunities for both still photographers and cinematographers alike during the "magic hour", the time just before dawn or at dusk when available light is often beautiful but scarce. Even at high ISO settings, the camera's intelligent noise reduction systems manage noise without sacrificing fine details, giving the D800 the edge. The difference can even be seen in low-contrast subjects such as hair and grass textures, which are often essential elements of cinema as well as high-resolution portraits and landscape images. High image quality at higher ISOs also means that you can shoot still images handheld more confidently, knowing that fast shutter speeds will reduce blur.
A strategic approach to turn light to your advantage
Combining both high-resolution performance and a wide ISO sensitivity range has finally become a reality. Nikon engineers have developed intelligent new methods to manipulate light transmission to the sensor's photodiodes: from the optical low-pass filter and on-chip gapless micro lenses to the image sensor's internal design, every measure has been taken to maximize and improve light transmission in order to deliver crisp, brilliant images with significantly less noise. All this is possible under a wide variety of lighting conditions, enabling you to get the most out of your NIKKOR lenses.
Optical low-pass filter optimized for sharpness on the D800
Reducing false colour and moiré is the main job of the optical low-pass filter located in front of the image sensor. However, this benefit is generally gained with a small sacrifice of sharpness. Moiré occurs in scenes containing repetitive details, such as strong vertical lines in architecture. Finding the right balance between benefits and sacrifices is the key to higher image quality, and that is what the D800's optical low-pass filter delivers. As a result, the astounding 36.3 megapixels unleash their potential through an optimized balance between sharpness and effectively prevented moiré and false colour. Furthermore, the multi-layer structure of the D800 low-pass filter utilizes layers of antireflective coating that have been optimized for the camera, contributing to sharper and clearer images.
The ultimate attention to detail — the D800E
Nikon engineers have developed a unique alternative for those seeking the ultimate in definition. The D800E incorporates an optical filter with all the anti-aliasing properties removed in order to facilitate the sharpest images possible.This is an ideal tool for photographers who can control light, distance and their subjects to the degree where they can mitigate the occurrence of moiré. Aside from the optical filter, all functions and features are the same as on the D800.
Note: The D800E carries an increased possibility that moiré and false colour will appear, compared to the D800. IR cut and antireflective coating properties of the optical filter remain the same with both versions.
Nikon Integrated Dust Reduction System that includes an Image Sensor Cleaning function
Any dust that reaches the image sensor results in unattractive spots on your images. To prevent this, the D800 employ Nikon's Integrated Dust Reduction System, which includes a self-cleaning sensor unit with four different resonance frequencies to vibrate the optical low-pass filter and shake dust away from the sensor. This function can be set to operate automatically when the camera is turned on or off, or to manual.
EXPEED 3 image-processing engine: speed, versatility, and high performance
High-megapixel still images are detail-rich but data-heavy. With the D800, however, you don't have to sacrifice speed for this privilege. Dedicated to understanding speed and its role in image making, Nikon engineers designed a powerful EXPEED 3 image-processing engine exclusively for digital SLRs. From image processing and card recording to image playback and image transfer, EXPEED 3 manages massive amounts of data at faster speeds than EXPEED 2. Even with specialized processing features like Active D-Lighting and high ISO noise reduction, capture speed is not affected. EXPEED 3 is so powerful that it handles data-intensive tasks such as Full HD video recording at 30p with ease. You'll also notice the difference in your still images and videos through minimized noise and even richer colours and tones. In addition to these fundamental advantages, the D800 reduce the kind of colour phase shift that some cameras have difficulty with in similar situations.
14-bit A/D conversion and 16-bit image processing for rich tones and natural colours
Tonal gradation is where an image transforms from simply representing life to taking on a life of its own. The D800 do exactly that, with cutting-edge image processing that injects vital energy into your images. Black is rendered as pitch black, and shadow details are subtle and rich. Even under harsh, high-contrast light, where some cameras can fail, the D800's gradation remains smooth with abundant detail and tone all the way up the scale to pure white.
Lateral chromatic aberration reduction: Take full advantage of your NIKKOR lens collection
High-megapixel sensors can really test the quality of your lenses, but you can be confident that the combination of brilliant NIKKOR lenses and Nikon's intelligent processing measures will significantly reduce lateral chromatic aberration to give you incredibly natural-looking results. Unlike other correction methods that simply eliminate chromatic aberration, Nikon's method compensates for these colour differences in a resolving index for each colour, making it particularly effective in producing images with stunning edge-to-edge sharpness. Moreover, because these corrections are made regardless of the NIKKOR lens used, this feature contributes substantially to achieving the sharpest images possible.
Advanced Scene Recognition System with 91K-pixel RGB sensor
Nikon's revolutionary Advanced Scene Recognition System, introduced with the flagship D4 camera, is also employed in the D800. At its core is a 91K-pixel RGB sensor that meticulously analyzes each scene with the fine resolution. The RGB sensor can recognize your scene's colours and brightness with unprecedented precision, then use that information to implement various automatic controls and give you more natural-looking results. The real breakthrough, however, is that the sensor can detect human faces with startling accuracy when shooting through the optical viewfinder. Along with face detection, detailed scene analysis is utilized to support more accurate autofocus, auto exposure and i-TTL flash exposure results in a diverse range of compositional and lighting situations. The improved subject tracking is most noticeable when using 3D-tracking, which can maintain a focus on moving subjects smaller in size than with previous generations.
More accurate face detection in auto-area AF and subject tracking in 3D-tracking
Auto-area AF and 3D-tracking are AF-area modes unique to Nikon that use your subject's colour and brightness information to detect focus. With the D800 and their more precise information and subject recognition advancements, expect big steps forward for both AF-area modes when taking high-quality still images. In auto-area AF, the camera can genuinely detect human faces and focuses on them immediately — useful when faces are a priority and there's no time to choose focus points. When using 3D-tracking, the sensor's fine resolution combines with a specifically optimized AF algorithm to realize unprecedented subject tracking precision, recognizing detailed patterns to keep your subject in sharp focus.
3D colour matrix metering III
Professional photographers who shoot still images know that Nikon's metering system delivers supremely well-balanced exposures. Thanks to the 91K-pixel RGB sensor, the D800 have far more detailed scene information at its disposal — including detected face information. This data helps the 3D colour matrix metering III deliver more desirable auto exposures, especially when there are human faces present. When the D800 detect a human face in a backlit situation, the camera determines the overall exposure while prioritizing the facial exposure, which might otherwise be underexposed. When a face is lit from the front and appears much brighter than the background, the camera recognizes the situation and avoids blowing out the facial details.
More balanced results in i-TTL balanced fill-flash and Active D-Lighting
Nikon's i-TTL system has long been considered the most accurate flash control system in photography, but now face detection and highlight analysis by the 91K-pixel RGB sensor pushes performance even further. With the D800's enhanced i-TTL balanced fill-flash, you can more precisely illuminate people's faces in relation to their surrounding brightness using either the built-in flash or an external hot-shoed Nikon Speedlight. For weddings and fashion shoots, or any photography that relies on the highest-quality still images, this new standard redefines what a flash system should be. Face detection also makes a difference when Active D-Lighting is used to retain highlights and shadows in high-contrast lighting situations. Faces will be optimally exposed both in the sun and in the shade.
Light source identification for auto white balance in still images
The D800's auto white balance is incredibly accurate in a diverse range of shooting situations, aided by unique Nikon technology that effectively identifies your light sources, both natural and artificial. With the 91K-pixel RGB sensor and the image sensor working together, the camera renders white as white with supreme accuracy. Or if you prefer, the auto white balance can be set to reflect the warmth of ambient, incandescent lighting.
Contribution to D-Movie shooting
The D800's Advanced Scene Recognition System enhances not only still image shooting but also various controls used in movie shooting. It identifies light sources and human faces finely, utilizing the high resolution of the image sensor to deliver accurate auto white balance and exposure control during movie shooting, and improves the precision of subject-tracking AF. Furthermore, it automatically detects flicker effects, and controls the exposure to reduce them.
Direct access to Picture Control that enables quick setting
Customize the look of your stills and videos through Picture Controls by fine-tuning parameters such as sharpening, saturation, and hue. The D800 now allow you to access Picture Control instantly and directly from a dedicated button rather than entering the menu. When live view shooting, you can visually confirm how customized Picture Control settings will look and easily adjust the parameters.
D-Movie shooting functions
Full HD video quality and minimized rolling shutter effect: Dynamic movie shooting in diverse lighting situations
Many filmmakers, multimedia professionals and still photographers need the highly mobile, lightweight and compact form of a D-SLR in order to cover large events or make documentaries, music videos or movies. For these professionals, the D800 are ready to create true cinematic experiences. By using the B frame data compression method, you can record 1080p Full HD video at 30p in H.264/MPEG-4 AVC format with unmatched moving image integrity for up to approx. 29 min. 59 s* of recording in a single clip. Thanks to Nikon's latest image-processing optimizations, the monumental power of 36.3 megapixels transforms to sharp, exquisitely rendered videos. Expect exceptionally smooth gradation in blue skies, with minimum block noise and beautifully natural movement rendered clearly and sharply. The D800's intelligent image sensor reads out movie images at faster rates than ever, significantly reducing the rolling shutter distortion that can occur during panning shots or when shooting fast-moving lateral subjects like trains. Thanks to EXPEED 3, your movies will take on a distinctive look of their own, even with dimly lit scenes. Combine these benefits and you'll begin to realize exactly the new creative opportunities possible for photographers and cinematographers alike. *Maximum recording time varies according to frame rate, frame size and image quality settings. Maximum recording time for time-lapse photography is 20 min.
Multi-area mode Full HD D-Movie: Creative movie-making freedom in FX- and DX-based formats
The D800 are designed to stimulate cinematographers to explore different moods and perspectives by enabling Full HD and HD video recording in two frame formats; Nikon FX- and DX-based movie formats in just one camera. When using wide-aperture NIKKOR lenses, the large image area of the FX-based format* renders exquisitely shallow depth of field with beautiful bokeh effects. The DX-based format uses an image area similar to 35mm movie film, allowing cinematographers to shoot with picture angles that they are accustomed to. Having the advantage of two D-Movie formats in one camera and an arsenal of NIKKOR lenses makes the D800 an incredibly versatile movie-making tool. *The aspect ratio of movies is 16:9 whichever format is selected. Also, in the FX-based movie format, the width of the image area is approx. 91% of that in the still image FX format.
Smoother video recording under fluorescent or mercury lamps: Auto flicker reduction
With the D800, it is easier than ever to reduce flicker effects during live view and video recording. Simply use auto in the flicker reduction menu to automatically identify the flicker frequency at the beginning of live view and switch to the one that will work best. You can also manually switch between 50 Hz and 60 Hz.
Comprehensive high-fidelity audio recording control
The D800 are designed for crisp stereo recording with a built-in external stereo microphone input. Attach the compact ME-1 Stereo Microphone to record clear sound while significantly reducing mechanical noise. An external headphone jack enables you to effectively monitor and control audio in isolation. While the audio level indicators offer visual confirmation of audio level, the microphone sensitivity can be controlled precisely in 20 incremental steps.
View simultaneous live view output on external monitors and record uncompressed video via HDMI
During movie shooting, you can now simultaneously check videos on an external monitor* using an HDMI connection, in addition to the camera's TFT monitor. And for those who need the purest video output for professional quality editing, you can now record uncompressed movie live view footage directly to an external storage device via HDMI interface. *When video is output through HDMI interface simultaneously with recording to a CF/SD card, output image through HDMI interface will be smaller than 1,280 x 720.
Capture a variety of scenes and subjects at a breathtaking pace. The D800's time-lapse photography lets you set intervals and frame rates in order to dramatically relay slow-moving activity at dramatic speeds. The D800 allow you to shoot time-lapse photography with replaying rates from 24 times to 36,000 times faster than normal. Time-lapse photography files can be saved as a movie file.Note: Movie files of time-lapse photography will be saved in 16:9 aspect ratio. It is recommended to confirm image area in movie live view before starting time-lapse photography.
Versatile custom settings for D-Movie
The D800 have addressed useful feedback from videographers with convenient custom controls for D-Movie operation. Instead of rotating the command dial, power aperture enables smoother aperture controls during movie live view using a button designated via custom menu, which can be very convenient to confirm depth of field. Index marking helps you locate important frames for later-stage in-camera editing and replay by attaching markers during movie recording. Markings are indicated along with the progress bar, which is easy to confirm visually.
Still image shooting functions
Advanced Multi-CAM 3500FX autofocus sensor module for razor-sharp detection in low light
Accurate AF detection is crucial for extremely high-resolution still images in every situation. The 51 sensor points in the D800’s AF sensor module work down to -2 EV (ISO 100, 20°C/68°F), the approximate physical limit of human visibility through an optical viewfinder. For even more powerful detection, you can rely on the camera’s 15 crosstype sensors in the center to detect both vertical and horizontal lines when using any AF NIKKOR lenses of f/5.6 or faster. What’s more, AF can be activated with eleven focus points in the center with open aperture of f/8*, which is a big plus when you combine a telephoto lens with a 2.0x teleconverter to shoot distant subjects. *Cross-type sensor is limited to the center AF point only. AF may not be achieved in lowcontrast or low-light conditions.
Versatile AF-area modes
Whether it's a still life, a portrait, a landscape or a candid street scene, your subject matter varies, but its importance doesn't. That's why the D800 offer four AF-area modes, each specifically tailored to adapt to various subjects. Single-point AF is ideal when you need pinpoint focus on stationary subjects. Dynamic-area AF has three options (9-point, 21-point and 51-point) and is ideal for shooting moving subjects. The selected AF point and the surrounding points keep your subject in sharp focus even if it briefly leaves the selected points. 3D-tracking allows you to maintain focus on subjects that are moving erratically from side to side. Auto-area AF detects human faces and prioritizes their sharpness for you — an ideal choice for candid photography.
Choosing AF mode and AF-area mode combinations
Control your desired AF mode (continuous or single servo) and AF-area mode (single-point, dynamic-area, 3D-tracking or auto-area AF) without ever taking your eye away from the viewfinder. By using a dedicated AF-mode button and command dials, you can switch between modes without interrupting your creative flow.
Glass prism optical viewfinder with approximately 100% frame coverage
See every important element in your frame clearly and precisely. The D800 offer approx. 100% frame coverage (in FX format) from its slim pentaprism, giving you the visually comfortable FX-format advantage and an unobstructed view when shooting still images. The viewfinder image is not only large and bright — the focusing screen is also carefully designed to help you sense sharp focus intuitively, be it manual or autofocus.
High-precision, high-durability shutter
The D800's shutter unit has been tested to well over 200,000 cycles of release to prove durability and precision. While the shutter unit designed to run at a speed range of 1/8,000 to 30 s, its intelligent self-diagnostic shutter monitor automatically monitors actual shutter speeds in order to correct possible variances that can occur over time.
High-precision sequential control mechanism
For true digital SLR excellence, the camera's mechanical structure, power and precision are vital to ensure indispensable speed and reliability. That's why Nikon utilized its engineering expertise to refine the powerful sequential control mechanism that drives the shutter, mirror, and aperture independently. As a result, shutter release can be operated with mirror-up position during live view. Because mirror-down movement is not required, you can expect even quieter still live view shooting. And as power aperture control operates via the stepping motor, the sound of mechanical adjustment is reduced for quieter and smoother control.
Active D-Lighting that reproduces brightness as you see it
Active D-Lighting preserves details in both highlights and shadowy areas of high-contrast scenes. colour reproduction is improved thanks to the image-processing engine EXPEED 3, and exposure control considering face brightness is achieved by the enhanced face detection performance of Advanced Scene Recognition System.
Expand dynamic range: HDR (High Dynamic Range)
The D800 can shoot two frames in a single shutter release, but at different exposures: one overexposed and one underexposed. The camera then instantly combines them to create an image covering a wider dynamic range. The range can be widened by up to 3 EV for different looks, all full of saturation and tonal gradation, while the smoothness of the edge where the two exposures meet can be adjusted for a more natural appearance.
Note: Tripod use is recommended.
Fast response time
The D800 are designed to respond immediately. Once the strategically located switch is turned on, the camera starts up in approx. 0.12 seconds* and your finger is in position for shutter release. Release time lag is minimized to approx. 0.042 seconds*, equivalent to that of the D3S, with continuous approx. 4 fps capability in FX format, approx. 5 fps in 1.2x and DX format and approx. 6 fps capability in DX format** with MB-D12.
*Based on CIPA Guidelines.
**When used together with batteries other than EN-EL15.
Shoot achieving reduced blur with zoom lenses in dim light: Auto shutter speed control for auto ISO sensitivity control
The D800 come equipped with an auto option for minimum shutter speed that automatically controls the balance between shutter speed and the ISO sensitivity based on the focal length of the lens being used. This can be particularly useful when using a zoom lens, because the camera can automatically choose the shutter speed to reduce camera shake. What's more, through the operation of ISO button and sub-command dial, auto ISO sensitivity control can be immediately turned on or off, without needing to enter the menu.
Shoot with multiple formats in one camera: Image area options
The D800 offer four image area options: FX format (35.9 x 24.0 mm), 5:4 (30.0 x 24.0 mm), 1.2x (30.0 x 19.9 mm), and DX format (23.4 x 15.6 mm) with all cropped image areas visually masked in the viewfinder. DX format offers approx. 1.5x, and 1.2x crop offers approx.1.2x telephoto effect. When a DX NIKKOR lens is used, DX format is automatically selected.
Get studio quality lighting virtually anywhere
Fast, versatile and portable, with Nikon Speedlights in your hands, your lighting possibilities are endless. The difference is a level of accuracy and flexibility that only the Nikon Creative Lighting System delivers. Its advantages are best experienced via Advanced Wireless Lighting. Using high-precision i-TTL flash control with strategic, intuitive operations, you can make lighting as powerful and comprehensive as your imagination can take it. Whether you shoot in the studio or in far-flung locations, there is a Nikon Speedlight solution to inspire your creativity.
Unparalleled lighting performance — SB-910 Speedlight
Nikon's SB-910 offers versatile i-TTL for on-camera or wireless flash control, a refined operability and a powerful guide number of 34/111.5 (ISO 100, m/ft, STD, FX format with zoom head set at 35mm). The SB-910's menus and controls have been improved for more operational ease. When a hard-type incandescent or fluorescent colour filter is attached, the SB-910 detects it and adjusts white balance instantly.
Capture NX 2 (optional): Optimal for processing images taken with the D800
To accommodate the imaging power of the D800's 36.3 effective megapixels, the latest Capture NX 2 now features powerful 64-bit processing. Capture NX 2 drastically simplifies an array of image enhancement procedures, letting you concentrate on making your pictures the best they can be. Instead of complicated layering and memorization, simply place a colour Control Point wherever you want to reprocess. colour Control Points use intuitive slider controls to make quick and easy adjustments to image characteristics such as brightness, contrast, saturation and tones. Change, adjust and experiment all you like, safe in the knowledge that all changes are non-destructive and an original always remains intact.

Double check that all setup instructions were followed accurately
Force close and relaunch Eden iPad app after settings/configurations are changed on either Eden dashboard or on the iPad
Verify that the iPad and printer are on the same wireless network
Ensure that the Eden application has permissions to find devices on local network
This sometimes can require deleting application, reinstalling from the app store and then re-adding tablet to the web dashboard
User will need to select “OK” to allow printer to be connected
Confirm that your printer can be discovered on the network by typing in the printer IP address into a search bar on a web browser (on iPad or computer)
IP Address found by navigating to WLAN > WLAN Status > Infrastructure Mode in the Badge Printer settings menu
Return to main Badge Printer screen when test printing or stepping through check-in workflow
If problems still persist, there might be some networking issues causing certain communications traffic to be blocked → See Advanced Configurations Requirements section
Advanced Configuration Requirements
Network issues can be difficult to diagnose and troubleshoot. The below suggestions might fix your issue, but attempting to connect over different networks or creating a new network for the iPad and printer might be the quickest path to resolution.
Your firewall, DLP software, or other network configuration settings/software may interfere with the ability of iPad and Badge Printer to communicate.
Please ensure that the following ports are open on your local network: UDP 161, TCP 5900, TCP 910
If you have an Enterprise wireless authentication protocol set up (LEAP, EAP-FAST, etc), a server certificate may be required on both the printer and iPad
Ensure that both printer and tablet IP addresses are whitelisted on the network
You may find success by hardwiring the device to the network with a Lightning <> Ethernet adapter
Reminder: The printer only works on 2.4GHz or lower networks. Your check-in iPad associated with your badge printer must be on the same network as the printer, however, it can be either 2.4GHz or 5.0GHz. During printer configuration, the device will only find networks it can use.
Still having issues? Please contact your Eden Customer Success Manager to help with advanced troubleshooting.

How to Buy bluetooth transmitter and receiver?: Complete Buying Guide
Before you spend your hard-earned money on a product, it’s important to know what you’re getting for your money. To help you make the best buying decision, we’ve put together this guide on how to buy [replace_keyword?. We’ll walk through the buying process from Amazon and other places, including some basic tips and tricks to help you get the best deal possible.
One thing to keep in mind is that a highly rated product does not always mean it is also worth buying. It is, therefore, crucial for a person to look into various factors alongside reading through product reviews. These are the factors that you probably ought to have at your fingertips before finally making a purchase decision:
- Quality: The quality of a product will depend on how long it lasts and how well it works. So it’s important to get the high-quality bluetooth transmitter and receiver to get the best output.
- Performance: When buying anything, performance is a key factor. The performance will determine if it meets your expectations or not.
- Functionality: A product’s functionality is also an important consideration. If it does not perform as advertised, then there is no use in spending money on something that doesn’t work properly.
- Price: Price is also an important factor when buying bluetooth transmitter and receiver as nobody wants to spend more money on something that does not give him any benefit or value for money
- Your Needs: One of the most important things when buying bluetooth transmitter and receiver is to be clear about your needs and requirements.
- Buyer Review: Before making the buying decision, you should understand what other people think of a bluetooth transmitter and receiver. One of the best ways of gathering information on products you might be interested in is to use buyer reviews posted by actual customers.
Consider these to get the best one:
Materials used in bluetooth transmitter and receiver
The first thing you can look for is the material of the bluetooth transmitter and receiver. The bluetooth transmitter and receiver should be made from high-quality material to last a long time. This way, you will not always have to buy new ones. The best material for making bluetooth transmitter and receiver is stainless steel because it does not rust or corrode easily. It also has a good finish and looks nice on any kitchen countertop or table.
Check the quality
Before buying bluetooth transmitter and receiver, make sure that it will serve its purpose for a long time and will not break down in a short period. Quality also ensures you get what you have paid for and nothing less than that. Never go for cheap products because they are not durable and can break easily. The best products will serve you for years, and at the same time, they are also available at an affordable price range. So always check the quality of a product before buying anything from anywhere.
Another thing that should be considered while buying a product is its features. You should know what all features this particular product has and how useful these features will be for you. If there is more than one feature available in the market, then you must check out all those features before buying one as they may not be useful in all cases or situations, but some of them might help you a lot during your day-to-day life. You should also check whether the product you want to buy is worth its price or not. You should compare it with other similar products available in the market and then decide whether it is a good option. If you have many options available, go for one that will give you maximum benefits at a lower price tag.
Some people prefer to spend a little more on an item that will last longer and provide better results, while others would rather buy something cheaper. When considering the price, it is important to remember that you get what you pay for. A high-quality bluetooth transmitter and receiver might cost more than a cheap one at first glance, but if they break down after only a few months of use, you may have lost more money than if you had just bought an inexpensive pair in the first place.
Think about how often you plan on using your new purchase and how long it will last. For example, if you are looking for a new bluetooth transmitter and receiver and will be using it frequently for many years, then spending more money on a quality bluetooth transmitter and receiver will be worth it in the long run. However, plan on using it less often or only want to use it occasionally. Spending less money on an inexpensive model may be more suitable because it won’t need as much care and maintenance as used frequently by multiple people every day or week.
Another thing to look out for when buying a bluetooth transmitter and receiver is value. This means you should always ensure that your product gives you value. The best way to do this is by looking at the price of the product, as well as its features. If it has many features but is still fairly cheap, then there’s a good chance you are getting value for money. If you are going to spend your hard-earned money on a product, it should be one that will last. This means that you need to look for quality materials and workmanship. Doing this will ensure that the product lasts longer, so you won’t have to keep spending money on new ones.
Ease of use
Another thing to look out for when buying bluetooth transmitter and receiver is the ease of use. How easy it is to use will depend on what you will use it for. This is because ease of use ensures that anyone who wants to buy your product will not have any trouble using or operating it. So always make sure that you buy products that are easy to use.
Many websites on the internet contain reviews from customers who have already bought products from those sites; therefore, we should always check those reviews before buying anything online! Reading these reviews will help us know how good or bad a bluetooth transmitter and receiver is and whether we should buy it. The more people have reviewed it, the more accurate will be your decision-making process. A good rule of thumb is that if most reviewers recommend something with a 4+ star rating on Amazon, then there’s a good chance that it will work well for you too.

Atoms make liaisons because they get more stability. A proof is that to break a liaison, we need to give energy to the molecule.
Atoms in a molecule are at a given distance, and oscillate slightly from this position depending on the energy they receive.
The atoms cannot oscillate at any frequency. There are authorized levels of energy at which the atom can be placed.
Even at n=0, the fundamental state, the atoms oscillates at a given frequency.
It is difficult to approach more the atoms from each other but it also requires energy to pull them away. The dissociation energy is the energy required to separate two atoms by an “infinite” distance.
To form a liaison, the clouds of electrons around the nuclei concentrate between the two nuclei to shield their charge and decrease the repulsion between them. The repartition of electrons differs depending on the type of liaison. New orbitals, molecular orbitals are formed from the atomic orbitals to bind two atoms.
Only the last layer of electrons, the electrons of valence, is taken in account for the molecular orbitals: the inner layers are too distant to interact.
4 types of liaisons exist: covalent, ionic, metallic and coordinative liaisons (or hydrogen bridges). We will develop the two first types of liaison here
Such a liaison is made between atoms of same electronegativity (or almost). Each atom put one electron in common to make a covalent liaison. The electrons in the liaison are shared equally along the liaison.
Such a liaison is made between atoms of different electronegativity. In an ionic liaison, the electrons are not shared equally. One atom is the donor of electrons and the other is the acceptor of electrons. The acceptor is more electronegative than the donor.
As the electrons are not equally shared, a gradient of charge exists along the liaison. We say that there is a dipolar moment.
H and F have different electronegativities (2.1 and 4 respectively). Most of the electrons of the liaison are thus closer to the atom of fluorine than to the atom of hydrogen.
The dipolar moment μ of this liaison can be defined as
By definition, the dipolar moment goes from the positive charge to the negative one. If the charges were completely separated, this moment should be
D stands for Debye and equals 3.336Cm.
The value obtained experimentally is 1.83D. It means that the hydrogen does not totally give its electron to the fluorine. The ionic character of a liaison is given by
And if this value is over 50%, we consider that the liaison is an ionic liaison.
Fluorine has the highest electronegativity but has not a polarity large enough to have an ionic bond with the hydrogen (only 41.6%). The reason is that both H and F have a very small radius and that the liaison’s length is thus small and the liaison is strong. It is the reason why HF is a weak acid while the other acids of halogen are strong acids: the negative charge is more stabilised on Cl–, Br– and I– than on F–.
Note that a molecule that has polar bonds is not automatically polar CH4 is nonpolar. The polyfluorocarbon (CF2)n is nonpolar as well.
Polar molecules are soluble in polar solvents and nonpolar molecules are soluble in nonpolar solvents. In polar solvents, the acceptor and the donnor of electrons dissociate because the charges of the ions are stabilised by the solvent molecules (the solvation has been explained in the section on the nucleophile substitutions). For instance, when we put some NaCl into water, the salt dissociates into the ions Na+ and Cl–. If this salt is put in a nonpolar solvent, NaCl remains as one molecule.
On jackets, nonpolar molecules are grafted so that rain does not penetrate the jacket but can only roll on it. On a nonpolar surface, water does not spread but restricts its surface at the maximum, forming a sphere.
Rule of the octet and formal charge
Through bonding, atoms try to have 8 electrons of valence, the electronic configuration of noble gases. For example CaCl is not a correct molecule. Ca has 2 electrons of valence and Cl has 7. To bind, Ca gives one electron to Cl. Cl reaches the octet but Ca has still one electron of valence to lose. The correct formula is CaCl2: Ca gives one electron to two Cl to reach the electronic structure of the noble gas Argon.
In CO2, the liaisons are covalent and the electrons are shared between C and O. CO2 could possibly have two structures:
One can see that the oxygen’s of the molecule of the left are not equivalent. In a molecule, the electronic distribution has to be the most homogeneous possible. Each atom has a formal charge (FC)
Let’s check the FC of each atom:
In the molecule of the right, atoms don’t have formal charges and this molecule is thus more stable than the molecule of the left, where charges are separated. In fact, the first molecule is a resonance form (i.e. a structure with the same composition but a different electronic repartition), but less stable, of the second molecule:
The rule of the octet works very well for the three first lines of the Mendeleev table. After that, some empty nd orbitals can be used to bind atoms. For example S can bind 6 atoms of fluor (SF6).
Now, is that molecule really linear, as we draw it? To determine the spatial structure of a molecule, we have to consider the atomic orbitals of each atom and the fact that liaisons are repulsive between each other (they are densely negatively charged). CO2 is thus linear, having an angle of 180° between the two double liaisons to reduce the repulsion between them. CH4 is a regular tetrahedral, having an angle of 109° between each liaison:
The black triangle is a liaison going in the direction of the reader and the dashes represent a liaison goind in the opposite direction.
The lone pairs also take space in a molecule. In fact, they take more space than a normal liaison: the electrons are piled up near the atom. As a result, H2O is not linear but is a tetrahedral. Yet, it is not a regular tetrahedron as the angle between the lone pairs (>109°) is greater than the distance between the liaisons (<109°). NH3 is tetrahedral as well but has the specific particularity that it quickly oscillates between two equivalent forms:
We have seen earlier the forms of atomic orbitals (AO) and none of them was tetrahedral. The atomic orbitals mix together to form new molecular orbitals (MO) that are used to bind with other atoms. It is the hybridisation process.
One of the molecular orbitals is outlined in red for convenience. These hybrid orbitals are the result of the hybridisation of the atomic orbitals s and p. The orbitals ns and np have different energies and merge into molecular orbitals sp of equal energies. Only the last layer of orbitals (with exceptions) merge to form a new set of orbitals. The inner orbitals are not modified as shown for NH3 next:
N has 5 electrons of valence: 2 in 2s and 3 in 2p. They merge into 4 sp3 orbitals of equal energy. The exponent 3 on the p indicates that 3 orbitals p were merged with one (not indicated as an exponent) orbital s. As usual, the electrons are placed on all the orbitals before being paired. One orbital contains 2 paired electrons already: it is the lone pair. The three other sp3 orbitals contains 1 electron each. The hydrogen will bring one additional electron on those orbitals to bind and form NH3.
We can do the same for H2O:
The oxygen has one more electron than the nitrogen. It results in a second lone pair and only 2 hydrogen’s binding to O.
For SF6, two empty 3d orbitals are used.
Four of the six liaisons are in the same plane and the two others are on each side of this plane. SF6 has thus a octahedral structure.
Bonding and antibonding orbitals
When two atoms are approaching each other, their outermost atomic orbitals interact to form molecular orbitals. We have seen earlier bonding orbitals but it is not the only possible combination of orbitals that can take place. The combination can either be positive or negative.
Li2 combines the 2s orbitals of each atom. The positive and negative combinations of the wave functions give
If we put this to the square, we obtain the probability of presence of the electrons. In the case of the negative combination, one can see that between the atoms, there is a point where the probability of finding electrons in null. It leads to an antibonding orbital. In the case of the positive combination, the probability of finding electrons between the atoms is high everywhere. It leads to a bonding orbital. Bonding orbitals are stable and lead to a persistent liaison. Antibonding orbitals are unstable and liaisons are not made. We denote those orbitals with a *. The molecular orbitals resulting from ns orbitals are called sigma σ:
The same kind of bonding and antibonding orbitals exist for the np, nd and nf orbitals. The np orbitals in the direction of the liaison form a sigma orbital and the other np orbitals are responsible for the double and triple liaisons and are called liaisons pi.
The molecular orbitals have different energies and we will now explain how to determine which orbitals are used and which ones are not.
The atomic orbitals of the two atoms are placed on the left and on the right. On the middle, we place the molecular orbitals that result from the atomic orbitals.
Each orbital gives one bonding and one antibonding molecular orbital. The molecular orbitals are placed from bottom to top, going from the less energetic to the most energetic orbital. For Z<8, the MO π2p and σ2p are inverted: the MO σ*1s and σ2s are repulsing each other. To determine the energy of a molecular orbital, we use the linear combination of atomic orbitals (LCAO) method. This method will not be explained right now, but probably in the second or third year lessons. Yet, as it is a linear combination, the average energy of the molecular orbital obtained from atomic orbitals equals the average energy of those atomic orbitals. For example, the energy of the molecular orbitals σ2s+ σ*2s equals the energy of the atomic orbitals 2s+2s. It is also the case when the atomic orbitals don’t have the same energy.
The second step is to distribute the electrons on the MO. The electrons are distributed from bottom to top and each molecular orbital accepts 2 paired electrons.
The effect of building those molecular orbitals is that the energy of the electrons has been decreased: only 2 electrons have a higher energy than the 2p orbitals but 6 have a smaller one (not counting the electrons from the 2s orbitals). The order of the liaison gives a good idea of the strength of the liaison and is given by:
The order tells us that the liaison between two oxygen’s is a double liaison. When the order of liaison is great, it means that the liaison is energetic and short.
Magnetism is the reaction of a particle to a magnetic field. As a reaction to a magnetic field, a particle orientates against the magnetic field or in its direction. This behaviour depends mainly on the electronic structure of the particle and on the temperature.
Diamagnetism is the opposition of any particle to a magnetic field. It appears in all materials but is very weak with regards to other magnetic behaviours. As a result, it is only observable in purely diamagnetic materials. To be so, a diamagnetic material has all its electrons paired. The opposite spins of paired electrons cancel the intrinsic electron magnetic moment: electrons are charged species revolving in one direction (spin) around the nucleus and can interact with an external magnetic field.
Unpaired electrons line up with a magnetic field and orientate particles in the same direction that the magnetic field. However, when the external field is removed, the particles do not retain the magnetic properties.
It is the strongest reaction to a magnetic field and is the property of magnets. As for paramagnetism, unpaired electrons line up with a magnetic field but an additional effect exists for ferromagnetic particles: the aligned, adjacent particles exhibit a magnetic dipole-dipole interaction. Under certain conditions, the orbitals of their unpaired electrons can overlap. As a result, a similar effect than the exclusion of Pauli applies: it reduces the electrostatic energy of the electrons when their spins are parallel and not anti-parallel. The difference of energy between the parallel state and the anti-parallel state is called the exchange energy and defines the strength of the ferromagnetism of a particle.
The colour of compounds comes directly from the difference of energy between the highest occupied molecular orbital (=HOMO) and the one above it (=LUMO, lowest unoccupied molecular orbital). The molecule absorbs light to excite one electron. To jump by one level, the photon must have the same energy that the difference of energy between the levels. It means that only the light of a given colour is absorbed. Because this colour is absorbed, we don’t see it but see the colours that are not absorbed by the molecule.
Fluorescence is the light emitted when an excited electron de-excites to an intermediate level instead of its fundamental level. The emitted colour is thus different than the one absorbed and the process is very slow.
In a metal, all the atoms are bound together. The molecular orbitals merge into a continuum band of conduction. As a result, the electrons are shared by all the atoms in the metal and electons can move along the metal. It is why metals conduct electricity.
Coordinative liaisons are liaisons made when an atom wearing one (or more) lone pair of electrons uses one pair to bind a cation.
The two electrons of a coordinative liaisons come both from one atom. The geometry of the molecule does not change when a coordinative liaison is made and the liaison has to be at the initial position of the lone pair.
In hydrogen bonds, the cation is a proton. These liaisons are weaker than a normal covalent liaison but can have an important role in the structure of a compound.
For example, the difference between ice and water is the proportion and the arrangement of the hydrogen bonds. Indeed, the hydrogen bonds are working in synergy to strengthen the structure. There is a restriction for the angle between the hydrogen bond and the other liaison of the hydrogen, which depends on the compound. The presence and absence of hydrogen bonds have a big responsability in the structure, and thus the effectiveness, of proteins.
The cation can also be a metal of transition. In this case, the bonding molecule is called a ligand. The ligand will target the empty nd orbitals of the metal. The geometry of the resulting compound is tetrahedral or octahedral depending on the generated molecular orbitals.
The atomic orbitals nd splits into two levels of different energy. The lower energy orbitals are dxy, dxz and dyz for the octahedral structure and the orbitals dx2-y2 and dz2 have a higher energy.
It is the opposite for the tetrahedral structures.
The chemistry of coordination is a complex domain of the chemistry and it will be discussed in details in the courses of second year.
1. What is the formal charge of the atoms with a *?
2. Which of those diatomic molecules are paramagnetic and what is their order of liaison? O2, N2, C2, F2, B2
3. What is the spatial structure of these molecules?
CO2, NO2, H20, CH3+, C2H6, BF3, C2H2, HCN
4. Explain why SiF4 is nonpolar while the liaison Si-F is polar.
5. Do these molecules have a dipolar moment? CCl4, HCl, F2, CO2, H2O, (C2ClH3)n
6. Why is the angle of liaison in SCl2 equal to 101°?
7. What is the hybridisation of the underlined atoms in these molecules? What is the spatial geometry around them?
H2O, XeF4, PCl5
Butyric acid: FCO*=6-4-4/2=0
Potassium permanganate: FCMn*=7-0-14/2=0
Chlorous acid: FCCl*=7-4-6/2=0
Thionyl chloride: FCS*=6-2-8/2=0
2. Let’s focus on O2 and then extend the reasoning to the other species. Each oxygen atom has 6 electrons of valence. To determine if a molecule is paramagnetic, we need to know if there are unpaired electrons. To do so, we apply the LCAO (linear combination of atomic orbitals).
There are 2 unpaired electrons in the π*2p orbital. O2 is thus paramagnetic. The order of the liaison is given by
For the other species, we can do the same thing. Nitrogen has one valence electron less than the oxygen. The π*2p orbitals are thus unoccupied and N2 is not paramagnetic. The order is (8-2)/2=3.
C2: paramagnetic, order: 2
B2: not paramagnetic, order: 1
F2: not paramagnetic, order: 1
3. CO2: linear
4. The dipolar moments of the liaisons cancel each other.
5. CCl4: No
6. The S atom has 6 valence electrons, as the oxygen does. It means that S has a sp3 configuration with 2 liaisons and 2 lone pairs. The normal angle between liaisons for the sp3 configuration is 109.5° and there is a smaller angle in SCl2 because lone pairs take more space than liaisons because electrons are packed nearby the atom.
7. H2O: sp3

Field Directed Sputter Sharpening (FDSS)
A proprietary process developed by Tiptek co-founders, FDSS sharpens the probe tip to atomic dimensions in a self-limiting fashion that does not require skilled operator intervention. The resulting probe tips give high resolution over long periods of use.
An animation of the FDSS process. An electrical bias on the probe creates a field (shown in blue) at the tip apex. Energetic ions directed towards the tip are deflected by the field, which grows stronger as the tip gets sharper. This ion milling process results in an atomically sharp tip.
Today this innovation has led to in-house, U.S.-based manufacturing operations delivering solutions for four areas:
- Scanning probe microscopy
- Transfer of lamella formed by focused ion beams (FIB)
- Scanning electron microscope-based nano-probers used in semiconductor failure analysis, and
- Leading edge research in atomically precise manufacturing (APM)
Atomically Precise Manufacturing
Tiptek is at the forefront of APM research and looks to the future where atomic scale features will be manufactured deterministically. Namely, each atom will be placed in a predetermined position creating atomic structures without flaws. These methods will be applicable to making any nanoscale device or object, such as microelectronics or devices for quantum computing.

Lucas Wiring Colours
Lucas Cable Colours, Sizes and Identification
In the 1950`s the widely used Lucas electrical system layout of wiring cables were standardised for all British made home and export vehicles, this included both cars and commercial vehicles. We hope the information given below will prove useful to the vehicle restorer, (or indeed someone simply trying to trace a fault) to simplify the identification and selection of cables on British manufactured vehicles.
All cables used are of the multiple strand type, this provides flexibility and a much reduced risk of breakage. Each cable is given an identifying symbol which shows the number of individual wires or strands, and the total number of these strands. Therefore a cable conductor comprising 28 strands of copper wire, each a thickness of ·012 inch diameter, or 30 S.W.G is denoted by 28/·012.
The safe current carrying capacities of the 44/·012, 28/·012 and 14/·012 cables are, respectively, 22, 14 and 7 amperes. Note: For long cables giving a definite voltage drop owing to the increased electrical resistance, it is often necessary to use a size larger cable than given above.
The principal of the Lucas colour cable system is that of the feed cable, switch cable and return (earth). Feed cables have outer braiding of one colour only, but all switch cables have the main colour of the feed cable together with a tracer (coloured) woven spirally into the braiding, while return or earth cables are black. When components are switched or controlled on the earthed side, that is, with the switch wire on the return side instead of the feed side, this is indicated by the use of a black tracer.
There are seven main colours, Brown, Yellow, White, Green, Blue, Red and Black, the following are the circuits in which these colours are used:
Brown Cables - For the Battery Circuit. From the battery or starter motor switch to the ammeter or control box, also to a radio set if fitted, from the control (regulator) box terminal A1. Also from the starter motor switch to the electric clock, inspection sockets and battery auxiliary fuse. This usually feeds the electric horn, cigarette lighter, interior lights etc.
Yellow Cables - For the Generator (Dynamo) circuit. From the dynamo terminal D to the corresponding control box terminal and the ignition warning lamp.
White Cables - These are used for the ignition circuit.and other circuits used only whilst the ignition is switched on, but do not require to have fuses, for example, the electric petrol pump, starter motor, solenoid switch etc.
Green Cables - All Auxiliary Circuits which are fed through the ignition system switch but are protected by the ignition auxiliaries fuse, for example, the brake stop lamps, fuel guage, direction indicators, windscreen wipers etc.
Blue Cables - Headlamp Circuits. These are fed from the terminal S2 (or H) on the lighting control switch.
Red Cables - The Side and Tail Lamp Circuits. These are fed from the terminal S1 (or T) on the lighting control switch. Other lamps which are included in this circuit are panel lamps, fog lights and other lamps which are required only when the side (parking) lamps are in use.
Black Cables - Used for the Earth Circuits. Should an electrical component not be earthed internally to the chassis frame a black cable is taken to a good earthing point on the chassis.

The operating system runs the computer hardware, and it provides a stable means for applications to use the hardware. The operating system is normally split into two main ingredients: the kernel as well as the file system.
The kernel performs many functions, which include networking, procedure supervision, and managing system resources. The file system is in charge of storing data, as well as communicating when using the lower level IO subsystem. It offers an API for app programmers to access files.
The operating system works with a variety of approaches to protect info and control hardware. Some of these features contain hardware control, encryption, and isolation.
The OS must provide a user interface, such as a command word line interface. These extrémité are used by simply users to interact with the operating system straight.
The OPERATING SYSTEM provides a number of different statistics, that really help analyze the performance belonging to the hardware. These kinds of statistics may be used to identify virtually any potential bottlenecks or difficulties with the components.
One of the most significant operating system stats is CPU utilization. This statistic may be analyzed for the whole system or perhaps for individual try this out CPUs in a multiprocessing environment. It can help detect single-threading issues and scalability concerns.
Operating systems should also provide specific statistics about drive performance. These kinds of statistics will tell you how quickly the disks happen to be responding, as well as the length of hard drive queues and current response time.
One more set of stats is historic performance data. This information is crucial to foreseeable future capacity organizing and progress management.

Hashgraph is a distributed consensus algorithm and data structure designed to achieve high levels of scalability, security, and fairness in decentralized networks. It was developed by Leemon Baird and introduced in 2016. Hashgraph aims to address some of the limitations and challenges faced by traditional blockchain systems.
At its core, Hashgraph is a directed acyclic graph (DAG) data structure that records and orders transactions. Unlike traditional blockchains that rely on a linear chain of blocks, Hashgraph organizes transactions in a graph structure, which allows for parallel processing and faster transaction confirmation times.
The key principle behind Hashgraph is a consensus algorithm called “gossip about gossip” or “gossip protocol.” In this algorithm, nodes in the network communicate with each other by gossiping information about the transactions they have seen. This information includes both the transaction data and the history of communication between nodes.
By exchanging gossip, nodes gradually build a graph that represents the order and dependencies of transactions. Through a series of rounds and virtual voting, consensus is achieved on the order and validity of transactions. This consensus process is asynchronous, meaning that nodes can participate in the consensus algorithm at any time without relying on a fixed time slot.
Hashgraph also incorporates a Byzantine fault-tolerant (BFT) consensus mechanism, which ensures that the system can tolerate malicious nodes or attacks without compromising the security and correctness of the network.
Benefits of Hashgraph include high transaction throughput, low latency, fairness in transaction ordering, resistance to DDoS attacks, and strong security guarantees. However, it’s important to note that Hashgraph is a patented technology, and its implementation is subject to specific licensing terms.
Overall, Hashgraph presents an alternative approach to achieving distributed consensus and has gained attention for its potential applications in areas such as cryptocurrency, supply chain management, decentralized finance (DeFi), and more.
Here’s a simplified explanation of how Hashgraph works:
Gossip Protocol: Nodes in the network communicate with each other by gossiping information. Each node sends a message to a few randomly selected nodes, sharing the information it has about transactions and the history of communication.
Event Creation: Each node collects incoming messages and creates events. An event represents a specific action, such as a transaction or the receipt of a gossip message. Events are timestamped with the node’s local time and assigned a unique hash.
Event Ordering: Nodes use a consensus algorithm called “virtual voting” to determine the order of events. In each round, nodes exchange virtual votes that contain their preferences for the order of events. The voting process is asynchronous, allowing nodes to participate at any time.
Gossip about Gossip: In addition to gossiping about transaction information, nodes also gossip about the voting information they have received. This process is known as “gossip about gossip.” It allows nodes to build a directed acyclic graph (DAG) that represents the order and dependencies of events.
Hashgraph Data Structure: The directed acyclic graph (DAG) created through the gossip about gossip process is known as the Hashgraph. It contains the complete history of events and the voting information associated with each event.
Consensus and Finality: As nodes continue to exchange gossip, they gradually reach consensus on the order of events. Once consensus is achieved, the order of events becomes finalized, and nodes can determine the state of the network at any given point in time.
Byzantine Fault Tolerance: Hashgraph incorporates a Byzantine fault-tolerant (BFT) consensus mechanism. This means that the algorithm can tolerate a certain number of malicious or faulty nodes without compromising the security and correctness of the network.
By utilizing the gossip protocol, virtual voting, and the Hashgraph data structure, Hashgraph achieves high transaction throughput, low latency, and fairness in transaction ordering. It offers strong security guarantees and can resist various types of attacks.

The SPRI Golf Sports Medicine Program includes the use of leading-edge biomotion technology, golf coaching and physical assessments. Below, learn more about the technology used for this innovative program:
SPRI’s Biomotion Laboratory is equipped with some of the world’s most advanced technology, including a 20-camera, 12-megapixel 1100 frames-per-second video motion analysis system, Bertec force-sensing platforms (embedded in the floor) and wireless electromyographic sensors for analyzing muscle function. This equipment provides detailed measurement of the kinematics (motion) and kinetics (forces) that generate movement. Combined with our advanced analysis software, the lab can comprehensively assess an individual’s biomechanical profile for nearly any activity or sport.
In addition to general assessments of movement quality, the lab software can provide detailed, sport-specific analyses. A specialized Qualisys module specifically assesses the biomechanics of the golf swing. This software provides an in-depth view into how an individual’s movement may impact their golf swing, providing detailed metrics on swing components such as the kinematic chain, ground reaction force, center of pressure and club motion. Applications for these technologies go well beyond simply helping the average golfer improve his or her game. Our unique, multidisciplinary team (combining orthopaedic biomechanics experts in the Biomotion lab, the leading orthopaedic surgeons and athletic trainers of The Steadman Clinic, the rehabilitation specialists from Howard Head Sports Medicine and a PGA Master Professional) can use this comprehensive data to guide those recovering from injury or with an underlying orthopaedic condition to improve their physical function and optimize their performance.
The Biomotion technology is complemented by a cutting-edge golf simulator from Foresight Sports. This simulator includes the most advanced and precise launch monitor (the GC Quad), which utilizes infrared object tracking and high-speed, high-resolution camera-based technology to precisely measure every aspect of club head and ball launch performance. By capturing thousands of images per second, building a virtual 3D model and then analyzing a multitude of data components, the technology creates the most accurate and complete picture of ball and club head performance, delivered in nearly real time.
The biomotion measurements can be performed within the golf simulator, providing a unique linkage between the whole-body motion assessment and the resulting ball trajectory. The golf pro and client can immediately see the real-world results of changes in swing biomechanics, in terms of both distance and accuracy. This unique combination of technologies ensures that individuals get the full picture of their golf performance, from inside out.
Add the unparalleled graphic technology and simulation experience to the most advanced biomechanical assessments available, and participants of the SPRI Golf Sports Medicine Program will enjoy a one-of-a-kind experience, supported by state-of-the-art technology backed by a legacy of research.
The Titleist Performance Institute-certified (TPI-C) physical therapists and golf specialists at Howard Head Sports Medicine (HHSM) conduct a full physical screen that includes top-of-the-line Keiser pneumatic machines to identify strengths and limitations. This helps determine how participants’ bodies affect their golf performance.
HHSM TPI-C therapists are musculoskeletal experts who are dedicated to understanding and solving for body limitations, dysfunction and prior injuries. The goal of the physical assessment at HHSM is to give participants actionable ways to improve speed, strength, balance and movement patterns while preventing injury.

In September 2016, rivals Google, Facebook, Amazon, IBM and Microsoft joined forces to create the Partnership on AI to Benefit People and Society (Partnership on AI). In January 2017, even Apple pushed past its famous secrecy to join this new cause along with six nonprofits: the Association for the Advancement of Artificial Intelligence (AAAI); the ACLU; Open AI; UC Berkeley; MacArthur Foundation; and the Peterson Institute of International Economics (PIIE). The Partnership on AI seeks to establish and share best practices for artificial intelligence (AI) systems.
The Partnership on AI just announced on its blog that 22 new organizations joined the consortium. They are committing themselves to several new initiatives such as working groups, “a challenge series to inspire people to use AI to address social issues,” an “AI, People, and Society” Best-Paper Award, and a civil society fellowship program.
The eight new companies are eBay, Intel, McKinsey & Company, Salesforce, SAP, Sony, Zalando, and a startup called Cogitai. The 14 new nonprofit partners are the Allen Institute for Artificial Intelligence, AI Forum of New Zealand, Center for Democracy & Technology, Centre for Internet and Society – India, Data & Society Research Institute, Digital Asia Hub, Electronic Frontier Foundation, Future of Humanity Institute, Future of Privacy Forum, Human Rights Watch, Leverhulme Centre for the Future of Intelligence, UNICEF, Upturn, and the XPRIZE Foundation.
Humanity is at an inflection point in the evolution of artificial intelligence. Due to the relatively recent convergence of ever-increasing computer power, big data, and algorithmic advances, AI today offers both benefits and threats. The Partnership on AI addresses issues such as transparency, security and privacy, values, and ethics, and provides an open and inclusive platform for discussion and engagement.
According to Bill Gates, when it comes to artificial intelligence, “we are summoning the demon.” The subtext is that a dystopian future awaits humanity if machine learning begins “breaking bad” and goes unchecked—or that we may be engineering our own extinction. Though it is not presently one of its objectives, the Partnership on AI may eventually contribute to governments having regulatory oversight of AI advancements at national and international levels.
In the near term, there are other worries and opportunities. AI may present challenges such as fairness and potential biases in algorithms, which is something the ACLU in particular may be watching. UNICEF is already applying machine learning, data science, and AI to societal problems, in line with one of the Partnership on AI’s thematic pillars. UNICEF developed the Magic Box platform, which allows collaborators like IBM, Google, Amadeus, and Telefonica to pool data and develop models for real-time decision-making in emergencies.
These challenges require deep interdisciplinary and cross-sector collaboration. The Partnership on AI demonstrates laudable responsibility and leadership from these otherwise fiercely competitive companies and individuals working together and with leading nonprofit organizations to safeguard the future. With the advent of self-driving cars, with artificially intelligent pacemakers, trading systems, power grids, and so much else, there are reasons for concern. Preventing an arms race in lethal autonomous weapons is an effort Human Rights Watch and other NGOs joined in 2012. The UN is placing “killer robots” on its agenda this year.
Ultimately, the future of AI depends on who controls it—and whether it can even eventually be controlled. AI is like nuclear energy, capable of both great good and terrible harm. Right now, the Partnership on AI is looking for its own leadership in its search for its first executive director. Interested candidates should be in touch with the search firm, Isaacson & Miller.—James Schaffer

For decades, engineers have envisioned wearable displays for pilots, surgeons, and mechanics. But so far, a compact wearable display that's easy to interact with has proved elusive.
Researchers at Fraunhofer Institute for Photonic Microsystems (IPMS) have now developed a screen technology that could help make wearable displays more compact and simpler to use. By interlacing photodetector cells--similar to those used to capture light in a camera--with display pixels, the researchers have built a system that can display a moving image while also detecting movement directly in front of it. Tracking a person's eye movements while she looks at the screen could allow for eye-tracking control: instead of using hand controls or another form of input, a user could flip through menu options on a screen by looking at the right part of the screen. The researchers envisage eventually integrating the screen with an augmented-reality system. [...]
Eye-tracking technology is nothing new, of course. Over the years, researchers have developed a number of systems that follow a person's gaze to allow him or her to interface with a computer. Often, the applications are for physically impaired people, but they can also be designed for a general computer user. [...]
The researchers built the system by first designing a light-sensing chip, which features a pattern of evenly spaced photodetectors. This was then fabricated at a commercial semiconductor manufacturing facility. A wafer containing multiple chips was then placed in a deposition chamber, where layers of organic material were deposited in between the photodetectors. These layers make up the organic light-emitting diodes, or OLEDs, that create the display. The mosaic of photodetectors and OLEDs is then encapsulated in a thin polymer film to protect it. [...]
The camera in the researchers' current prototype is still fairly rudimentary. It has a resolution of only 12 pixels, which means that it can't yet track a user's eye movements. However, Scholles says that the team has developed a 160-by-120-resolution version of the camera chip that has been tested in the lab, but not yet integrated with a display. The researchers expect to have an advanced version of the system, complete with higher-resolution camera and full eye-tracking capability, by early 2011."

Web designers currently face the increased proliferation and diversity of new touch devices which pose major challenges to the design task. We developed W3Touch–an interface instrumentation toolkit for web designers to collect user performance data for different device characteristics in order to help them identify potential design problems for touch interaction. Web designers can visualise the data aggregated by W3Touch and use simple metrics to automate the adaptation process for many different viewing and interaction contexts.
The figure below illustrates the adaptation process based on W3Touch for an example page. The adaptation using W3Touch consists of three steps. First, the user interaction is monitored and relevant data collected for each metric. Second, W3Touch implements visualisation techniques for inspection of the raw data and segmentation of the interface into critical components based on thresholds defined for each metric. Based on these visualisations, designers may adjust the thresholds and experiment with different adaptations. Finally, they can deploy an adaptation catalogue fixing the design problems identified for different contexts. In the example, the links in the sidebar navigation are displayed larger and with more spacing, enabling precise selection without the need for zooming.

Tungsten light sources
The first electric headlamp light source was the tungsten filament, operating in a vacuum or inert-gas atmosphere inside the headlamp bulb or sealed beam. Compared to newer-technology light sources, tungsten filaments give off small amounts of light relative to the power they consume. Also, during normal operation of such lamps, tungsten boils off the surface of the filament and condenses on the bulb glass, blackening it. This reduces the light output of the filament and blocks some of the light that would pass through an unblackened bulb glass, though blackening was less of a problem in sealed beam units; their large interior surface area minimised the thickness of the tungsten accumulation. For these reasons, plain tungsten filaments are all but obsolete in automotive headlamp service.
Tungsten-halogen light sources
Halogen technology (also “quartz-halogen”, “quartz-iodine”, “iodine”, “iode”) makes tungsten filaments more efficacious producers of light — more lumens out per watt in — and Europeans chose to use this extra efficacy to provide drivers with more light than was available from nonhalogen filaments at the same power consumption. Unlike the European approach which emphasised increased light output, most U.S. low beam halogens were low current versions of their nonhalogen counterparts, producing the same amount of light with less power. A slight theoretical fuel economy benefit and reduced vehicle construction cost through reduced wire and switch ratings were the claimed benefits. There was an improvement in seeing distance with U.S. halogen high beams, which were permitted for the first time to produce 150,000 candelas (cd) per vehicle, double the nonhalogen limit of 75,000 cd but still well shy of the international European limit of 225,000 cd. After replaceable halogen bulbs were permitted in U.S. headlamps in 1983, development of U.S. bulbs continued to favour long bulb life and low power consumption, while European designs continued to prioritise optical precision and maximum output.
The first halogen bulb for vehicle use, the H1, was introduced in 1962 by a consortium of European bulb and headlamp makers. This bulb has a single axial filament that consumes 55 watts at 12.0 volts, and produces 1550 lumens ±15% when operated at 13.2 V. H2 (55 W @ 12.0 V, 1820 lm @ 13.2 V) followed in 1964, and the transverse-filament H3 (55 W @ 12.0 V, 1450 lm ±15%) in 1966. H1 still sees wide use in low beams, high beams and auxiliary foglamp and driving lamps, as does H3. The H2 does not see wide use any more because it requires an intricate bulb holder interface to the lamp, has a short life and is difficult to handle. For those reasons, H2 was withdrawn from ECE Regulation 37 for use in new lamp designs (though H2 bulbs are still manufactured for replacement purposes in existing lamps). The use of H1 and H3 bulbs was legalised in the United States in 1997. More recent single filament bulb designs include the H7 (55 W @ 12.0 V, 1500 lm ±10% @ 13.2 V), H8 (35 W @ 12.0 V, 800 lm ±15% @ 13.2 V), H9 (65 W @ 12.0 V, 2100 lm ±10% @ 13.2 V), and H11 (55 W @ 12.0 V, 1350 lm ±10% @ 13.2 V). 24-volt versions of many bulb types are available for use in trucks, buses, and other commercial and military vehicles.
The first dual-filament halogen bulb (to produce a low and a high beam with only one bulb), the H4, was released in 1971. The U.S. prohibited halogen headlamps until 1978, when halogen sealed beams were released. To this day, the H4 is still not legal for automotive use in the United States. Instead, the Americans created their own very similar standard (HB2/9003). The primary differences are that the HB2 sets more strict requirements on filament positioning, and that the HB2 are required to meet the lower maximum output standards set forth by the United States government.
The first U.S. halogen headlamp bulb, introduced in 1983, was the 9004/HB1. It is a 12.8-volt, transverse dual-filament design that produces 700 lumens on low beam and 1200 lumens on high beam. The 9004 is rated for 65 watts (high beam) and 45 watts (low beam) at 12.8 volts. Other U.S. approved halogen bulbs include the 9005/HB3 (65 W, 12.8 V), 9006/HB4 (55 W, 12.8 V), and 9007/HB5 (65/55 watts, 12.8 V).
Halogen infrared reflective light sources (HIR)
A further development of the tungsten-halogen bulb has a dichroic coating that passes visible light and reflects infrared radiation. The glass in such a bulb is spherical, rather than tubular. The reflected infrared radiation strikes the filament located at the centre of the sphere, heating the filament to a degree greater than occurs by passing an electric current through the filament. The filament thus superheated emits more light, without an increase in power consumption or a decrease in lifespan.
HID (xenon) light sources

HID stands for high-intensity discharge, a technical term for the electric arc that produces the light. The high intensity of the arc comes from metallic salts that are vapourised within the arc chamber. These lamps are formally known as gas-discharge burners, and produce more light for a given level of power consumption than ordinary tungsten and tungsten-halogen bulbs. Because of the increased amounts of light available from HID burners relative to halogen bulbs, HID headlamps producing a given beam pattern can be made smaller than halogen headlamps producing a comparable beam pattern. Alternatively, the larger size can be retained, in which case the xenon headlamp can produce a more robust beam pattern.
Automotive HID lamps are commonly called ‘xenon headlamps’, though they are actually metal halide lamps that contain xenon gas. The xenon gas allows the lamps to produce minimally adequate light immediately upon powerup, and accelerates the lamps’ run-up time. If argon were used instead, as is commonly done in street lights and other stationary metal halide lamp applications, it would take several minutes for the lamps to reach their full output. The light from HID headlamps has a distinct bluish tint when compared with tungsten-filament headlamps.
Xenon headlamps were introduced in 1991 as an option on the BMW 7-series. This first system used an unshielded, non-replaceable burner designated D1 — a designation that would be recycled years later for a wholly different type of burner. The AC ballast was about the size of a building brick. The first American-made effort at HID headlamps was on the 1996-98 Lincoln Mark VIII, which used reflector headlamps with an unmasked, integral-ignitor burner made by Sylvania and designated Type 9500. This was the only system to operate on DC; reliability proved inferior to the AC systems. The Type 9500 system was not used on any other models, and was discontinued after Osram’s takeover of Sylvania. All HID headlamps worldwide presently use the standardised AC-operated bulbs and ballasts.
Burner and ballast operation
HID headlamp bulbs do not run on low-voltage DC current, so they require a ballast with either an internal or external ignitor. The ignitor is integrated into the bulb in D1 and D3 systems, and is either a separate unit or integral with the electronic ballast in D2 and D4 systems. The ballast controls the current to the bulb. The ignition and ballast operation proceeds in three stages:
- Ignition: a high voltage pulse is used to produce a spark — in a manner similar to a spark plug – which ionises the Xenon gas, creating a conducting tunnel between the tungsten electrodes. In this tunnel, the electrical resistance is reduced and current flows between the electrodes.
- Initial phase: the bulb is driven with controlled overload. Because the arc is operated at high power, the temperature in the capsule rises quickly. The metallic salts vapourise, and the arc is intensified and made spectrally more complete. The resistance between the electrodes also falls; the electronic ballast control gear registers this and automatically switches to continuous operation.
- Continuous operation: all metal salts are in the vapour phase, the arc has attained its stable shape, and the luminous efficacy has attained its nominal value. The ballast now supplies stable electrical power so the arc will not flicker.
Stable operating voltage is 85 volts AC in D1 and D2 systems, 42 volts AC in D3 and D4 systems. The frequency of the square-wave alternating current is typically 400 hertz or higher.
HID headlamp burners produce between 2,800 and 3,500 lumens from between 35 and 38 watts of electrical power, while halogen filament headlamp bulbs produce between 700 and 2,100 lumens from between 40 and 72 watts at 12.8 V.
Current-production burner categories are D1S, D1R, D2S, D2R, D3S, D3R, D4S, and D4R. The D stands for discharge, and the number is the type designator. The final letter describes the outer shield. The arc within an HID headlamp bulb generates considerable short-wave ultraviolet (UV) light, but none of it escapes the bulb, for a UV-absorbing hard glass shield is incorporated around the bulb’s arc tube. This is important to prevent degradation of UV-sensitive components and materials in headlamps, such as polycarbonate lenses and reflector hardcoats. “S” burners — D1S, D2S, D3S, and D4S — have a plain glass shield and are primarily used in projector-type optics. “R” burners — D1R, D2R, D3R, and D4R — are designed for use in reflector-type headlamp optics. They have an opaque mask covering specific portions of the shield, which facilitates the optical creation of the light/dark boundary (cutoff) near the top of a low-beam light distribution. Automotive HID burners do emit considerable near-UV light, despite the shield.
The correlated colour temperature of HID headlamp bulbs, at between 4100K and 4400K, is often described in marketing literature as being closer to the 6500K of sunlight compared with tungsten-halogen bulbs at 3000K to 3550K. Nevertheless, HID headlamps’ light output is not similar to daylight. The spectral power distribution (SPD) of an automotive HID headlamp is discontinuous, while the SPD of a filament lamp, like that of the sun, is a continuous curve. Moreover, the colour rendering index (CRI) of tungsten-halogen headlamps (≥0.98) is much closer than that of HID headlamps (~0.75) to standardised sunlight (1.00). Studies have shown no significant safety effect of this degree of CRI variation in headlighting.
The HID headlamp light sources (bulbs) offer substantially greater luminance and luminous flux than halogen bulbs — about 3000 lumens and 90 mcd/m2 versus 1400 lumens and 30 mcd/m2. If the higher-output HID light source is used in a well-engineered headlamp optic, the driver gets more usable light. Studies have demonstrated drivers react faster and more accurately to roadway obstacles with good HID headlamps rather than halogen ones. Hence, good HID headlamps contribute to driving safety. The contrary argument is that HID headlamps can negatively impact the vision of oncoming traffic due to their high intensity and “flashing” effect due to the rapid transition between low and high illumination in the field of illumination, thus increasing the risk of a head-on collision between the HID-enabled vehicle and a blinded oncoming driver.
Efficacy and output
HID burners give higher efficacy (produce more light from less power) than halogen bulbs. The highest-intensity halogen headlamp bulbs, H9 and HIR1, produce 2100 to 2530 lumens from approximately 70 watts at 13.2 volts. A D2S HID burner produces 3200 lumens from approximately 42 watts during stable operation. The reduced power consumption means less fuel consumption, with resultant less CO2 emission per vehicle fitted with HID lighting (1.3 g/km assuming that 30% of engine running time is with the lights on).
The average service life of an HID lamp is 2000 hours, compared to between 450 and 1000 hours for a halogen lamp.
Blind oncoming traffic
Due to their high intensity and unsual colour temperature, they can blind or enrage oncoming drivers, thus decreasing road safety and increasing the risk of head-on collisions.
Vehicles equipped with HID headlamps are required by ECE regulation 48 also to be equipped with headlamp lens cleaning systems and automatic beam levelling control. Both of these measures are intended to reduce the tendency for high-output headlamps to cause high levels of glare to other road users. In North America, ECE R48 does not apply and while lens cleaners and beam levellers are permitted, they are not required; HID headlamps are markedly less prevalent in the US, where they have produced significant glare complaints. Scientific study of headlamp glare has shown that for any given intensity level, the light from HID headlamps is 40% more glaring than the light from tungsten-halogen headlamps.
HID headlamp bulb types D1R, D1S, D2R, D2S and 9500 contain the toxic heavy metal mercury. The disposal of mercury-containing vehicle parts is increasingly regulated throughout the world, for example under US EPA regulations. Newer HID bulb designs D3R, D3S, D4R, and D4S which are in production since 2004 contain no mercury, but are not electrically or physically compatible with headlamps designed for previous bulb types.
Lack of backward-compatibility
The arc light source in an HID headlamp is fundamentally different in size, shape, orientation, and luminosity distribution compared to the filament light source used in tungsten-halogen headlamps. For that reason, HID-specific optics are used to collect and distribute the light. HID burners cannot effectively or safely be installed in optics designed to take filament bulbs; doing so results in improperly-focused beam patterns and excessive glare, and is therefore illegal in almost all countries.
HID headlamps are significantly more costly to produce, install, purchase, and repair. The extra cost of the HID lights may exceed the fuel cost savings through their reduced power consumption, though some of this cost disadvantage is offset by the longer lifespan of the HID burner relative to halogen bulbs.
LED light sources
The first series-production LED headlamps on the Lexus LS 600h
Automotive headlamp applications using light-emitting diodes (LEDs) have been undergoing very active development since 2004. The first series-production LED headlamps were factory-installed on the Lexus LS 600h / LS 600h L starting with the 2008 models. Low beam, front position light and sidemarker functions are performed by LEDs; high beam and turn signal functions use filament bulbs. The headlamp is supplied by Koito. Full-LED headlamps supplied by AL-Automotive Lighting were fitted on the 2008 V10 Audi R8 sports car except in North America. The Hella headlamps on the 2009 Cadillac Escalade Platinum became the first U.S. market all-LED headlamps. Present designs give performance between halogen and HID headlamps, with system power consumption slightly lower than other headlamps, longer lifespans and more flexible design possibilities. As LED technology continues to evolve, the performance of LED headlamps is predicted to improve to approach, meet, and perhaps one day surpass that of HID headlamps.
The limiting factors with LED headlamps presently include high system expense, regulatory delays and uncertainty, and logistical issues created by LED operating characteristics. LEDs are commonly considered to be low-heat devices due to the public’s familiarity with small, low-output LEDs used for electronic control panels and other applications requiring only modest amounts of light. However, LEDs actually produce a significant amount of heat per unit of light output. Rather than being emitted together with the light as is the case with conventional light sources, an LED’s heat is produced at the rear of the emitters. The cumulative heat of numerous high-output LEDs operating for prolonged periods poses thermal-management challenges for plastic headlamp housings.
Prolonged operation above the maximum junction temperature will permanently degrade the LEDs and ultimately shorten the device’s life. The need to keep LED junction temperatures low at high power levels always requires additional thermal management measures such as heatsinks and exhaust fans which are typically quite expensive.
Additional facets of the thermal issues with LED headlamps reveal themselves in cold ambient temperatures. Not only must heat be removed from the rear of the headlamp so that the housing does not deform or melt, but heat must in addition be effectively applied to thaw snow and ice from the front lenses, which are not heated by the comparatively small amount of infrared radiation emitted forward with the light from LEDs.
LEDs are increasingly being adopted for signal functions such as parking lamps, brake lamps and turn signals as well as daytime running lamps, as in those applications they offer significant advantages over filament bulbs with fewer engineering challenges than headlamps pose.

The successful launch of Geosynchronous Satellite Launch Vehicle (GSLV)-D5, powered by an indigenous cryogenic engine, from the Satish Dhawan Space Centre in Sriharikota, on Sunday has put India in the elite group of nations that can launch heavy satellites. The success comes after two back-to-back failures and one aborted mission involving the GSLV.
Only a few countries like the US, Russia, France Japan and China have mastered the cryogenic engine technology. India had been denied this technology for many years and had to depend on Russian technology for the previous GSLV launches. The launch vehicle, which has the capability of placing 2,000–2,500kg satellites into geosynchronous transfer orbit, will reduce if not completely stop India’s dependence on foreign launch vehicles.
At present, Indian satellites of this category are launched by foreign space agencies like Arianespace. The space agency spends around Rs500 crore for the launch of heavyweight satellites by a foreign space agency. However, the Indian Space Research Organisation (Isro) could launch these satellites onboard its own launch vehicle like the GSLV at nearly half the cost.
A satellite placed in a geosynchronous orbit matches earth’s rotation.
S Ramakrishnan, director of the Vikram Sarabhai Space Centre, where the launch vehicle was designed and developed, said: “At Isro, we used to call GSLV a naughty boy. But today the naughty boy is a very obedient boy.” Isro chairperson K Radhakrishnan said: “It is an important day for Indian science and space technology.”
“This achievement could have been possible 10 years ago if the Kerala police had not filed a baseless case against me... We can now look forward to higher capabilities in our space programme,” former Isro project director Nambi Narayan said.
Some of Isro’s other ambitious missions like Chandrayaan-2 and Human Space Flight Programme bank heavily on the GSLV. Prior to launching Chandrayaan-2, Isro will have to complete at least two successful launches using the GSLV.
49 metres is the height of the three-stage GSLV
415 tonnes (as much as 80 elephants), lift-off capacity
6573 kilonewton lift-off thrust of vehicle
1982 kg is the weight of the communication satellite GSAT-14 put into orbit
Rs 350 crore the cost of the mission by Isro
6 Isro becomes sixth space agency in world after US, Russia, Japan, China & France to taste success with indigenous cryogenic engine.

The OS keeps track of the Primary Memory; as in it keeps track of the memory which is in use and by whom, and the memory which isn't. Thus, it allocates the unused memory as and when a process or program requests it.
The Operating System allocates the Processor to a program and deallocates it when it is no longer required, ensuring that each program and application receives enough of the processor's time to function properly.
The I/O Controller of the OS keeps a track of all your devices and decides which process gets the device, when, and for how much time. It uses another API to request data from the device driver.

In this fast-paced technological era, electronic devices have become indispensable parts of our daily lives, including smartphones, computers, tablets, and smart home appliances. To ensure these devices continue to operate at their best, regular software updates play a pivotal role. This blog post delves into the reasons why consistent software updates are crucial for device performance.
First and foremost, prioritizing software updates is vital for improving device security as cybercriminals constantly evolve their tactics. They continuously search for vulnerabilities to gain unauthorized access to devices and personal data. However, software developers are equally proactive, working tirelessly to patch these security loopholes. By applying regular updates, you can rest assured that your device is equipped with the latest security protocols, thus protecting you from potential threats.
No software is perfect, and even well-designed applications may have bugs or performance issues. Consequently, software updates address these flaws, providing essential bug fixes and performance enhancements that significantly improve the overall stability and speed of your device. By keeping your device's software up to date, you can enjoy a smoother and more reliable user experience.
As technology advances, developers introduce innovative features that enhance the functionality and user experience of your devices. However, it is important to note that these new features may require the latest software version to run efficiently. By staying current with software updates, you can take full advantage of these new functionalities and experience the latest improvements offered by your device.
Another compelling reason to prioritize regular software updates is their potential to prolong the lifespan of your device. As software evolves, developers optimize it for improved resource management and efficiency. This optimization significantly reduces unnecessary strain on your device's hardware components. Consequently, the longevity of your device is extended, saving you from the need to replace it prematurely.
Furthermore, as operating systems and software continue to evolve, older versions may become incompatible with the latest applications and services. Consequently, regular updates ensure that your device remains compatible with new apps and services, enabling you to access the latest developments in the digital world. Staying up to date also enables you to receive better customer support and assistance from developers in case you encounter issues.
Maintaining the optimal performance of your devices requires regular software updates. From ensuring robust security measures to improving overall functionality and compatibility, updating your device's software is a vital aspect of responsible device ownership. Neglecting software updates can leave your device vulnerable to security breaches, reduce its performance, and limit access to new features and services.
Make it a habit to check for software updates regularly or enable automatic updates if possible. By doing so, you not only protect your device and data but also maximize its potential, ultimately enhancing your overall digital experience. Embrace the power of regular software updates and witness the positive impact they have on your device's performance and longevity.

Hello! after last month’s overview of some of our early graphical effects, I thought I would go into a bit more detail about one of them.
The Vector Field is a utility object that is very simple in theory – a grid is overlaid on the level and each point of this grid contains the current wind speed at that point (or whatever the appropriate thing is for the particular environment). Dynamic graphic objects like particles or soft bodies like hanging cloth can then sample the grid to find out how they should move.
The values in the vector field can be influenced by interactive objects moving past such as the player avatar, or created directly when scripts apply forces. They will then slowly revert to normal – the above image shows a simple debug rendering of the vector field values after a jump.
I originally got the idea from my friend Matricks who used it in Teeworlds. The grid scales quickly with size – especially in 3D environments – which means memory consumption, cache coherency and the processing needed to decay the grid cells become issues. Both Backworlds and Teeworlds are 2D games with reasonably small levels though, so it can be done on the CPU without much overhead – especially since every single cell does not need to be processed every frame. Other solutions could be to simply store the sources of power and their direction, to process everything on the GPU and/or heavily rely on dirty rectangles to figure out what needs to change but for our case the simplicity and flexibility of the vector field is hard to beat.
Above is a short animation showing a high-speed push through a particle stream and an object reacting to the vector field. This particular vector field has a relatively long decay time which means the particle stream actually changed direction for a short time, a shorter decay time would cause just a few particles to be offset before the stream resumed.

What would you do if you could sequence a human genome?
And what would you do if you could sequence a human genome in a matter of hours rather than weeks for only a fraction of today's sequencing cost?
The applications are countless, ranging from digital gene expression to diagnostic sequencing, but in more general terms it would mean a quantum leap forward to a more complete understanding of the information stored in our genetic material.
Quantapore is developing a novel, massively parallel sequencer, which will allow rapid, affordable and accurate sequencing of entire genomes. Our proprietary sequencing technology will eliminate the bottlenecks associated with today's sequencing methods, namely laborious sample preparation, short read length, high cost and limited throughput.
This capability will enable the sequencing of whole genomes within a day and thereby revolutionize the understanding, diagnosis, monitoring and treatment of a wide variety of diseases. In addition, the benefits of deciphering entire genomic information will be available to nearly everyone as the cost per genome will be reduced dramatically.
Reading the human genome.

Dear KUSP 2019 participants,
We welcome you to an exciting summer school in South Korea at the Institute for Basic Science (IBS). KUSP, the Korea Undergraduate/graduate/high-school Science Program, is designed to attract young researchers from all over the world, bring them together to tackle interesting physics projects, learn and have fun. For the first two weeks the students will follow physics lectures, and in the afternoon they will have hands-on experience either in the lab or with computer simulations working with IBS researchers. The next two weeks will include more extensive lab work and the final week the students will be writing or finishing up their reports as well as their posters. This program is a lot of fun and very interesting, offering a very fulfilling research experience. Get immersed in it, get involved, get messy, investigate, learn, have fun and be safe.
The KUSP was initiated in the summer of 2015 by the Center for Axion and Precision Physics Research of Institute for Basic Science (IBS/CAPP) and has continued for four summers very successfully with participants from many different countries. In particular, the two other IBS research centers, Center for Underground physics (IBS/CUP), and Center for Theoretical Physics of Complex Systems (IBS/PCS) have decided to join the KUSP in the summer of 2019 to offer the research opportunity to a limited number of students in particle and material physics, and related natural science disciplines from all around the world. The Center for Theoretical Physics of the Universe (IBS/CTPU) is also supporting KUSP 2019.
Center for Axion and Precision Physics Research
CAPP aims to launch a state of the art axion dark matter experiment. CAPP will also play a leading role in the proton electric dipole moment experiment and will participate in other axion, dark matter, EDM, muon g-2 experiments around the world.
The latest measurements indicate that dark matter constitutes about 27% of the energy in the universe. Among the leading dark matter candidates are particles such as axions, and weakly interacting massive particles (WIMPs), e.g., the lightest supersymmetric particle. (WIMP searches are the subject of several groups around the world including the IBS Center for Underground Physics in Korea.) Axions were postulated to solve an embarrassing problem in strong interactions: even though the theory of strong interactions predicts a large violation of certain symmetries (P-parity and T-time reversal), the limit on the electric dipole moment (EDM) of the neutron is already too small, some ten orders of magnitude smaller than expected.
A massive axion is excluded by several experiments and astrophysical limits. A prominent Korean theorist prof. Jihn E. Kim suggested that a light-mass axion would also work as well. The light axions have to advantage that they could constitute the dark matter of our universe. It is currently believed that axion masses between 10-3 meV and 1 meV could be ideal dark matter candidates. Depending on their mass, there could be about 1014axions/cm3, to fill the dark matter density quota of about 0.3GeV/cm3.
CAPP will explore the axion. Our first aim is to use a method suggested by Prof. P. Sikivie, to convert the axions into microwave photons inside a large volume, high magnetic field, and a high quality microwave cavity. We are also exploring different geometries that can prove to be advantageous. The axion microwave experiment is going to be launched at the KAIST campus top of the line equipment and technology. The expected conversion rate is very small, of order 10-23W, making it the faintest signal possible in a realistic experiment.
In addition, the center is going to play a leading role in the storage ring proton EDM experiment to improve the sensitivity by several orders of magnitude down to 10-29e.cm, making it the best hadronic EDM experiment in the world. A successful proton EDM experiment could help explain the matter-antimatter asymmetry mystery of our universe.
Center for Underground Physics
We now know that neutrinos are massive but we have yet to determine their absolute masses and nature. Discovering these important unknowns can be related to leptogenesis theories that make attempts to explain particle-antiparticle asymmetry in the universe. Neutrinoless double beta decay experiment is the most practical approach for determining the absolute masses and understanding the nature of neutrinos. At the Center for Underground Physics (CUP) at the IBS, we will perform several phases of AMoRE (Advanced Mo-based Rare process Experiment) experiments that probe the neutrino mass down to 0.03 eV.
Advancing our knowledge of dark matter is necessary in order to understand the origin and structure of the universe, because the universe consists of 26.8% dark matter and 68.3% dark energy. We are running experiments to search directly for WIMPs (Weakly Interacting Massive Particles), which offer the most plausible explanation as to the nature of dark matter. We will develop new detection techniques to search for dark matter, which would provide more sensitive results than currently running experiments.
We will install detectors with ultra-low noise at a depth of approximately 700 meters at our underground laboratory in Yangyang in Korea to reduce background cosmic rays to search for extremely rare events such as neutrinoless double beta decays, dark matter, etc. Since we expect to see only a handful of signal events per year, the success of the experiments highly relies on reducing background interference. We will achieve our goal by growing ultra-low background crystals and by developing low-temperature sensors that have excellent energy resolution and the power to distinguish the signals from huge background events.
Center for Theoretical Physics of Complex Systems
Today the eyes looking for novel technologies and new generation devices focus on nano- structured materials with unprecedented electrical, mechanical, optical and other properties like graphene, nanotubes, quantum dot arrays, metamaterials, trapped atomic condensates, superconducting networks, plasmonic and nanophotonic structures. There is an increasingly strong demand for new theoretical concepts, approaches and computational tools for uncovering fundamental nonlinear and quantum many-body processes in such systems and designing efficient methods of their control.
Our center aims to take up the grand challenge and to create a world-class laboratory for the nonlinear classical and quantum dynamics of nano-structured systems, and to conduct cutting edge research on phenomena at the interfaces of applied and computational theoretical condensed matter physics and optics. We aim to cross-fertilize research on exciton-polariton condensates, superconducting networks, quantum dot networks, ultracold atomic gases, optical waveguide networks, topology, frustration, flatband physics, Fano resonant nanoscale devices, artificial gauge fields, quantum ratchets, many body localization, disorder against interactions, artificial quasicrystals, nonintegrability, deterministic chaos, Arnold diffusion, KAM, coherence and decoherence, quantum stochastic dynamics, finite systems, targeted energy transfer, transport in nano structures, nonlinear naophotonics, topological insulators, and more.
An efficient Visitors and Workshop Program will ensure finest research and training standards thus developing the center into a leading institution able to successfully compete within a quickly globalizing science network. By becoming a meeting hub for the global scientific community the center will offer to young scientists an excellent research environment and connections with the worldwide leaders in a broad variety of emerging research fields.
Center for Theoretical Physics of the Universe
The IBS Center for Theoretical Physics of the Universe carries out research on particle physics and cosmology, which aims to understand nature at the most fundamental level and answer the questions about the origin of the universe.
The Standard Model of particle physics and Einstein's General Relativity provide an accurate description of almost all known physical phenomena over the scales from the subnuclear to the cosmic. However there are many reasons to believe that the Standard Model and General Relativity are not the final story, but merely a kind of approximation to a more fundamental theory. Astonishingly the most compelling reason comes from cosmic observations: the existence of dark matter and matter-antimatter asymmetry in the universe, which can not be explained by the Standard Model. As another compelling reason, the naturalness argument for electroweak symmetry breaking in the Standard Model suggests a possibility of new physics at energy scales around TeV. The quest for unification and a theory of quantum gravity also lead us to speculate about more fundamental theoretical frameworks such as grand unification and string theory.
The prime theme of our research is new physics beyond the Standard Model of particle physics, which can provide an answer to the following questions:
We are living in a very exciting era for particle physics and cosmology. What is the next fundamental theory that underlies the Standard Model of particle physics? We may be able to uncover it in the near future.

What is Amateur Radio ?
It is many different things to the individual, millions of people throughout the world who enjoy this very diverse communications hobby.
Below is a summary of how it began and has kept with the times to remain an enjoyable leisure time activity. In Canada an amateur radio licence (Certificate) is granted for life, there is no renewal requirement also there is no age requirement, radio operators can be of any age, and knowledge of Morse code is no longer required. There are three classes or levels of Certificate’s (No longer Licence) “Certificate of Proficiency of Amateur Radio” Basic, Basic with Honours, Advanced and also Morse Code 5 w.p.m endorsement, it is not required to have the Morse Code endorsement to operate using Morse Code.
Basic : The holder of an Amateur Radio Operator Certificate with Basic Qualification is limited to basically bands above 30mhz (Code endorsement with Basic allows you to operate below 30mhz) and a transmit limit of 250 Watts (DC)
Basic with Honours: To achieve “Basic with Honours” is receiving a mark of 80% or more on a Basic Exam, or you may chose to do a min 5 words per minute Morse code exam. (Note: Morse code is not a requirement for any class of Amateur Radio Licence in Canada.)
Advanced: Allows a more technical approach to Amateur Radio, where you are permitted to install and operate repeaters, run higher power design and build transmitters, along with more technical privileges.
Who are Amateur Radio Operators?
They are ordinary citizens, including some of your neighbours or work colleagues, and people all over the world. Are Amateur Radio Operators – also known as Ham Radio Operators.
One of the marvelous things about the hobby is that radio signals don’t stop at country borders – being a Amateur Radio Operator is like having an international passport.
You can visit the world on the airwaves, make casual acquaintances or life-long friendships, without even leaving home. Many long-time Amateur Radio Operators will tell you that some of their best friends are people they have never met in person.
Around the world Amateur Radio Operators have set up their own transmitting and receiving stations at home, in their cars, and even use hand-held radios to keep in touch while on foot. The friends they make could be someone across town, in a far-flung exotic country, or even astronauts on the International Space Station or Space Shuttle missions who are Amateur Radio Operators also!
How do Amateur Radio Operators contact each other?
When the hobby began around the turn of the 19th century the only form of communication radio amateurs (they were then known as amateur wireless experimenters) was Morse code, the same method used by the telegraph.
This form of communication has survived to still be in use today – and has become an international language enabling people who can’t speak the same language, to communicate.
Up until the 1920’s wireless telegraphy was the only way to transmit and receive information on the airwaves. But Amateur Radio Operators pioneered voice communications in the mid-1920s at the time when broadcast stations began.
Although the transmission and reception techniques have changed over the years with technical developments, voice communication remains the major method of communicating on the amateur bands.
In times of natural disasters, Amateur Radio Operators throughout the world provide support communications, and sometimes the only communications immediately after a disaster.
The radio systems of emergency services are also extremely busy, and additional or supplementary communication can be readily provided by radio amateurs using their own equipment, and skills.
The linking of computers to Amateur Radio has become popular. Often it is done using the sound card on a PC and software. There are several digital operating modes, each having its particular use. Mostly they provide keyboard communications.
If you would like to know more, do some research on FT8, PSK31, WSJT. The use of digitized voice via Amateur Radio is also expected to become common in the near future. The IRLP (internet radio linking project) and EchoLink are linking Amateur Radios and Repeaters through the internet.
The sending of pictures via radio was being done by Amateur Radio Operators long before television began.
This interesting aspect of Amateur Radio has several variations, from single-frame pictures through to full-colour real-time video that can be received on a domestic television receiver with UHF capabilities. There is also software available that permits fax to be sent over the radio.
Soon after the launch by the former Soviet Union of Sputnik 1, the world’s first man-made orbiting satellite, Amateur Radio Operators entered the space age with the OSCAR (Orbiting Spacecraft Carrying Amateur Radio) series of satellites.
The tradition of designing and building amateur satellites continues today. They are being launched as a piggyback load when major communications satellites are put into orbit. International contacts are possible by sending a signal to a satellite and having it relayed back to earth providing communications over many thousands of kilometers.
The method used to determine, at a distance, the source of a transmitted signal, are broadly as direction finding (DF), and have application in navigation systems.
But Amateur Radio Operators also effectively use DF when they take part in a popular activity called Foxhunting. This involves locating within a time limit a small hidden transmitter.
In some countries DFing is called Radio Sport, and involves a lot of footwork over reasonably lengthy courses, and is likened to a mix of DFing and another sport – orienteering.
Foxhunts can also be held over relatively short courses requiring Hounds to do all of their DFing while on foot.
Foxhunting basically uses a directional beam antenna, both vehicle mounted or out-the-window, and receiver to DF the general hiding spot of the Fox.
QRP (Low Power)
QRP is low power transmitting usually 5 watts or less, some Amateur Radio Operators challenge themselves or their equipment to make contact overseas with as little transmit power as possible, sometimes with less than 1 watt.
This is the world of “QRP” or Low Power Operation, where the goal is to reach as far as you can with as little transmitter power as possible.
Why? Yes, it seems strange when 100 watts is the norm, to want to transmit with five watts or much less – milliwatts. But it is the challenge of making your antenna as efficient a radiator as possible.
You may also like the challenge of making your own radios. QRP is a challenge to succeed with limited resources, and for many of its devotees it satisfies their desire to experiment, learn, and have fun.
And there’s much more!
Contests, awards, QSLing, eyeball-QSOs, Hamventions, special event stations, skills that can be used at work or school, and the list goes on, currently the production crew of the TV Show “Last Man Standing” (KA6LMS) operate and make contact with others with the actual Amateur Radio that is used on the set of the TV Show.

Really hear it.
Welcome to Wireworld Pro Audio – a division of Wireworld Cable Technology, the technology and innovation leader in high-end audio/video cable founded in 1992. While Wireworld cables have been used in recording and mastering studios for well over a decade, there is now a division specifically for the pro audio and music industries.
With a range of products from instrument cables to microphone/ balanced interconnects, digital audio cables, speaker cables and shielded power cords, our patented designs provide superior translation and the intense tone that musicians crave.
DNA HELIX – The goal of Wireworld’s patented DNA* Helix cable technology is to enable us to experience music without the losses and colorations normally caused by cables. Controlled listening tests show that the primary sonic effects of cables are caused by electromagnetic effects. The effect called eddy current resistance, which increases as strands are twisted, is especially problematic because it masks quiet musical details. To overcome those issues, the strands in the DNA Helix designs are completely parallel, providing the most direct signal path for the lowest eddy current resistance. These parallel strands run within flat insulated conductors layered in patterns that channel electromagnetic energy and reject interference.
Here's how it works.
*Delineated Neutralizing Array
UNI-PATH – The exclusive Uni-Path design used in Wireworld USB and HDMI cables provides similar advantages to the more complex DNA Helix design in smaller scale applications. Uni-Path improves electromagnetic efficiency and shielding, enabling more of the original signal information to be reproduced, improving both sound quality and video imaging.
FLUXFIELD –The Fluxfield design in our power conditioning cords features 24 insulated wires coiled around flat inner cores to maximize inductive and capacitive filtering. Twin high-density shields prevent noise from entering or radiating outward. These unique elements minimize noise and line resonances, especially with longer lengths. The flat, flexible design coils effortlessly for easy handling.
Wireworld was founded with the unique mission of perfecting audio cables through objective listening tests. With the invention of the CES Innovations Award winning Cable Comparator™ (US Patent 5,740,255), we created a better way to test cables for musical preservation. Our objective listening tests are far more revealing than normal cable comparisons because the cables are compared to a virtually perfect test control, a direct connection between components. We call these listening tests ‘Cable Polygraphs’ and we are now sharing 24/96 wave files of recorded cable tests in our Cable Polygraph Library.
Audio professionals around the world have verified the effectiveness of cable polygraph testing. Robert Harley, editor of The Absolute Sound, described cable polygraph testing as “illuminating insight into exactly how each cable affects the sound”. A leading author of audio engineering books, Bobby Owsinski, stated “I was a major skeptic that high end cables could offer any sonic improvement, but Wireworld changed my mind in a big way”. This testing advantage has led to several patents including the DNA Helix cable technology, and it has enabled us to optimize the material blends in our ultra-quiet Composilex 3 insulation. These powerful innovations have enabled Wireworld to create the highest fidelity audio cables in the world.
Highest conductivity premium quality materials.
A common misconception is that the gauge of a speaker wire is all that matters. Heavier is better, right? Wrong. Gauge can make a difference, but the cable design and material quality can have an even greater impact on performance. That is why we focus on developing the most efficient designs and producing them with the best quality materials available in each price range. For example, the conductors in our least expensive cables are oxygen-free copper and our ultimate cables use Ohno Continuous-Cast® 7N (99.99999% pure) solid silver.
Metal conductivity is equally important for plugs. Our silver-clad OFC plug contacts are three times more conductive than the common bright gold over nickel plating used on costume jewelry and most other brands.
Beyond the advantages of the best conductor materials, our second and third generation composite insulation, Composilex 2 and Composilex 3, preserve the purity of the signal by minimizing triboelectric noise better than any conventional low-loss insulation materials, including DuPont Teflon®. This proprietary material provides rewarding improvements in vividness, focus and dynamic contrast. With these innovations, Wireworld cables have advanced the art of reproducing the power and delicacy of music.

A love of music. A passion for innovation. A flair for industrial design. A quest for detail. The innate ability to prove the naysayers wrong time and time again. This is who we are. Like many audiophiles, David Salz has spent decades refining his music listening experience. He is truly passionate about using objective listening tests to create cables that preserve the finest details and expression of music. The closer we get to bringing the intensity and beauty of live music to your listening room, the closer we have come to achieving our goals.
It began in 1980, when David realized the only way to discover what was being lost by a cable was to remove it altogether. Instead of simply comparing cables, he began testing them against virtually perfect direct connections made by docking components together with custom adapters. The knowledge gleaned from decades of these tests led to several patents as David continued to develop cable designs that sound closer and closer to the ultimate purity of a direct connection. In short, David developed more effective testing that provided real answers and real solutions, not just different results.
In the '90s David partnered with V.P. / Operations, Sara Flaaten, and together they moved the company in a direction of steady growth and progress with dedication to loyal, well-trained staff and excellent customer service; people that take pride in creating a product that truly does live up to its reputation. Try Wireworld cables for yourself if the feeling of a live performance is what you want for your listening experience.

Matterport brings 3D capture to iPhone
iPhone users can now use a Matterport app to create, edit, and share high fidelity 3D digital twins of any physical space. The Matterport Capture app also allows users to embed notes, links, labels or videos, and share the data.
Visitors can explore the spaces in immersive 3D and digitally measure walls, doors, windows or furniture. iPads are also supported by the Matterport Capture app, available in the Apple App Store.
RJ Pittman, CEO of Matterport, said: “With billions of square feet captured in more than 80 countries, Matterport has created the standard for 3D capture to digitise the built world. Matterport for iPhone introduces the world to our advanced spatial data capture and Cortex AI technologies in an easy-to-use app that enables anyone to capture and share 3D spaces with friends, family or colleagues.”
Once downloaded, the Matterport Capture app can be used immediately in a number of powerful ways:
- Real estate agents can scan a property almost as easily as taking photos with their iPhone, to create and publish an accurate 3D digital twin of a property listing
- Homeowners can share a digital twin of their kitchen to get a quote for a remodel or scan damage to send to their insurance company for a more accurate estimate for repair
- iPhone users can freely share their digital twins with friends and colleagues, along with prospective tenants, owners, and more
- Interior designers can capture a space and take it with them to make sure furnishings fit
- Contractors can efficiently document stages of progression during the construction or renovation process
- Property owners can create an immersive virtual tour of their spaces to improve their booking rate on rental sites
- Businesses can easily capture a 3D digital twin of their office to help with recruiting, hiring, wayfinding, space planning and building company culture
- And anyone can capture and share places that are important to them — whether it’s a special room in their home, a favourite spot they frequent, or an incredible space they experienced on vacation.
Japjit Tulsi, CTO of Matterport, said:“We have been hard at work advancing the capability of the Matterport platform to support 3D capture from a range of new digital capture devices over the past two years. Matterport for iPhone marks an important milestone in our capability to create stunning 3D digital twins of any space using the phone in your pocket.”
Matterport for iPhone is powered by Cortex, the company’s AI platform and patented deep learning neural network. It analyses 3D spatial data captured from Matterport’s flagship Pro2 camera and a wide variety of third party devices including Lidar cameras, 360 cameras, and now smartphones. With millions of spaces captured, Cortex consistently and accurately creates the 3D digital twin and handles complex tasks, from 2D to 3D reconstruction, advanced image processing, automatic colour correction, object and room labelling, and more. Cortex can even generate professional looking photo galleries and shareable videos from within the digital twin, along with measurements and dimensions of entire spaces; and automatic face blurring for privacy.
Matterport clients include Redfin, HH Angus, Sotheby’s, Arup and Marriott, have captured billions of square feet of space in over 80 countries.

As a market leader in automated ultrasound reprocessing systems, Nanosonics’ trophon® technology helps protect patients by delivering consistent high level disinfection (HLD) of ultrasound probes with every automated cycle.
The trophon®2 device is manufactured in Australia and with an expanding global network of offices in major markets including USA, Canada, UK, France, Germany, Ireland, Japan and Australia along with an expanding distributor base across the world, Nanosonics has an established global supply chain to continue to provide unparalleled service and supply.
The global trophon device installed base has now increased to over 25,000 units worldwide with more and more facilities continuing to trust the trophon technology to deliver reliable, automated HLD.
The fully enclosed trophon technology generates a 'sonically activated' hydrogen peroxide (H2O2) mist which accesses all surfaces of the suspended probe, ensuring all crevices and imperfections of the probe surface are high level disinfected. The only by-products of the HLD cycle are oxygen and water. The trophon devices therefore effectively delivers HLD without damaging the sensitive probe surface, whilst reducing patients, staff and the environment to harmful chemicals.*
As a fully automated reprocessing system designed with the user in mind, trophon2 technology offers advanced workflow efficiencies. With traceability across the operator, probe and cycle parameters, trophon devices help demonstrate user compliance for survey and audit reporting.
*Compared to manual soaking methods.
With over 25,000 trophons now installed in major markets across the world, more than 80,000 patients every day are protected from the risk of ultrasound probe cross contamination.
The trophon® family includes trophon® EPR and trophon®2 which share the same core technology of 'sonically activated' hydrogen peroxide.

The role of the turbine is to transform the energy of water, steam or wind into mechanical energy that will make the generator spin. The generator transforms the mechanical energy into electricity. In hydropower plants, this combination of generator and turbine is called a generating unit.
In this generating unit, water rushes through the penstock and into the scrollcase. It turns the turbine blades and is then drawn to the turbine axis to exit through the underneath draft tube. The mechanical energy produced by the tremendous force that rushing water exerts on the turbine is transmitted to the generator, which then converts it into electrical energy.
The generator is connected to the turbine drive shaft. It has a moving part–the rotor–and a fixed part–the stator. The rotor's outer surface is covered with electromagnets. The stator's inner surface, or cylinder wall, is made up of copper windings. When the rotor turns inside the stator, the electrons in the copper windings "vibrate." Their movement generates an electric current, similar to the one created by Michael Faraday in his 1831 experiment on electromagnetic induction, but on a much larger scale.
Installation of a Kaplan turbine
All the generating units in a power system must be synchronized. In other words, it's essential that they maintain an exact rotation speed. Why? To ensure adequate power quality. Equipment that runs on electricity is designed to use alternating current of a specific frequency. This frequency depends on the generating unit's rotation speed, i.e., the number of times per second that rotor magnets travel past the stator windings. This frequency is expressed in cycles per second, or hertz (Hz), named after the German physicist Heinrich Hertz, who proved the existence of radio waves.
In North America, the standard alternating-current cycle is 60 times per second, but in Europe it is 50 times per second. This means that a clock designed to work at 60 Hz will be slower when plugged into a European socket.
Rotors at La Grande-3 generating station
At La Grande-3, the rotors have 32 pairs of electromagnets. To supply a 60-Hz alternating current, they must therefore rotate at a speed of 112.5 revolutions per minute (RPM).
Here is the formula that was used by the engineers:
32 pairs of electromagnets x 112.5 RPM
3,600 RPM or 60 revolutions per second (60 Hz).
Michael Faraday, a British physicist and chemist, discovers the induction phenomenon.
The scientist is the first to create an electric current by moving a magnet back and forth inside a metal winding. The innovative principles behind Faraday's discovery are quickly implemented and used to help meet the production needs of the industrial era. The first electric generator, precursor to today's generating units, was created based on these principles. Faraday's experiments sparked the invention, by other researchers, of the first electric motor and the first transformer (essential for the transmission of electricity).

Various Types of RAID
RAID stands for Redundant Array of Independent Disks and is widely used in commerical sectors. Using a RAID storage subsystem has the following advantages:
- Provides disk spanning by weaving all connected drives into one single volume;
- Increases disk access speed by breaking data into several blocks when reading / writing to several drives in parallel operations. With RAID, storage speed increases as more drives are added;
- Provides fault-tolerance by mirroring or parity configuration.
Common terms that you will need to understand more include:
NRAID stands for Non-RAID. The controller treats each drive as a stand-alone disk, therefore each drive is an independent logical drive. NRAID does not provide data redundancy.
JBOD stands for Just a Bunch of Drives. The capacity of all the drives is combined to become one logical drive (no block striping). In other words, the capacity of the logical drive is the total capacity of the physical drives. JBOD does not provide data redundancy.
RAID 0 provides the highest performance but no redundancy. Data in the logical drive is striped and distributed across several physical drives on the same volume.
RAID 1 mirrors the data stored in one hard drive to another. RAID 1 can only be performed with two hard drives. If there are more than two hard drives, RAID (0+1) will be performed automatically.
RAID (0+1) Disk Striping with Mirroring. This configuration combines RAID 0 and RAID 1 - Mirroring and Striping. RAID (0+1) allows multiple drive failure because of the full redundancy of the hard drives. If there are more than two hard drives assigned to perform RAID 1, RAID (0+1) will be performed automatically.
RAID 3 Disk Striping with Dedicated Parity Disk. One drive member is dedicated to storing the parity data. When a drive member fails, the controller can recover / regenerate the lost data of the failed drive from the dedicated parity drive.
RAID 5 Striping with Interspersed Parity. RAID 5 is similar to RAID 3 but the parity data is not stored in one dedicated hard drive. Parity information is interspersed across the drive array. In the event of a failure, the controller can recover/regenerate the lost data of the failed drive from the other surviving drive.
Fully understanding the physical storage configurations is a must for better manage and control your data storage strategic and emergency planning.

We're continuing our staff interviews to celebrate our 60th anniversary, and this week we turn our focus to our engineering team. In this interview with Inventus Power's Ilyas Ayub (Vice President, Technical Center Americas) and Sundy Liu (Vice President, Technical Center Asia), we'll discuss the benefits of having global engineering capabilities and how this has helped us develop safe, reliable, and quality-engineered battery systems across a broad range of portable, motive and stationary applications.
Can you tell us a little bit about your roles and the capabilities of each Technical Center?
Sundy: As Vice President, Technical Center Asia, I'm responsible for global project development and technology. I lead our Asia Pacific Engineering Team in Guangzhou, China which consists of nearly 200 engineers with industry expertise in mechanical, software, and electrical engineering. We can provide complete technical solutions and cover a wide range of product design platforms for battery packs and battery managements systems (BMS), chargers, and power systems. We also have a high-level agency in-house testing lab which streamlines the regulatory process for our customers. Our Technical Center Asia is the only facility certified by TUV for these standards in the South of China and we also have a UL-approved CTDP lab (Client Test Data Program).
Ilyas: As Vice President, Technical Center Americas, I oversee product development in the U.S. for battery packs and chargers. The Americas Engineering Team consists of a variety of talented mechanical, electrical, test and qualification engineers as well as field application engineers (FAEs). Our FAEs play a vital role at Inventus Power as they assist our sales team in winning new opportunities and ensuring we design products to the customer’s requirements. Historically the Americas Technical Center has engineered products for military and medical applications. Today, we are expanding into new applications for lawn and garden, material handling, and light electric vehicles. These new markets require medium to large format batteries to power their applications, and we are excited to be working on such complex projects.
Inventus Power has 300+ engineers worldwide. What are the benefits of having a global engineering team?
Ilyas: We benefit from the ability to co-develop products and utilize each other's strengths accordingly. For example, a product may be designed by the team in Guangzhou and our team in the US will provide customer support. We may also perform the electrical engineering for a project at one tech center and software engineering at the other. We also leverage each other's labs for qualification and agency certification.
Sundy: I agree with Ilyas. Our customers benefit from our co-development capabilities in product design and technology. Ultimately, our shared global resources help us deliver exceptional customer service and superior product design.
Market diversity is a strong suit of Inventus Power, servicing markets from consumer and industrial to medical and military. What engineering lessons have been learned from working with a variety of markets?
Sundy: The engineering team has accumulated extensive design experience in product application technology across different fields over the years. Inventus Power's ability to improve product technology, design system solutions across multiple platforms, and shorten the product design cycle allows us to meet the diverse market demand.
Ilyas: Our broad market diversity has enabled us to take the knowledge and lessons learned in one market/application and incorporate into the design products for other markets. For example, our military applications taught us how to ruggedize products for extreme conditions. Consumer applications taught us how to be cost-sensitive. If we purchase a large volume of cells to support a consumer battery pack, we can leverage the supplier relationship and utilize the cell pricing for other market applications.
Over the years, Inventus Power has moved up the power curve. What considerations need to be made when moving from smaller, simpler battery packs to larger, more complex systems?
Ilyas: Moving up the power curve means your battery packs are going to get more complex. From an electrical perspective, components must handle higher voltage and power. From a mechanical perspective, housing material selection is critical to be able support larger and heavier battery packs. As the battery gets bigger and more complex, there is a lot more software that needs to be developed to ensure proper cell management, communications with the host device, and more accurate state-of-charge (SOC) calculations.
Sundy: To further expand on Ilyas’s response, medium and large format battery packs require more complex system designs. This includes advanced engineering in the Battery Management System (BMS) as these larger battery packs need the correct thermal management controls such as cell balancing & uniform cooling methods, system safety design protections and power management. They also require enhanced communication systems for ensuring high-precision system detection & data collection, SOC calculations, high-speed CAN communication / compatibility with other communication protocols, and reliable State-of-Health (SOH) management. Finally, in addition to size, there are mechanical design considerations such as application of new materials for indoor/outdoor use (waterproof, radiation protection, shock/vibration protection, high impact, and reliable cooling).
Are there any plans for the Inventus Power Technical Centers you can share with us?
Sundy: The Guangzhou Technical Center is focusing on design innovations that will support Inventus Power's expansion into new markets. We are supporting custom designs as well as developing a new line of standard products. Along with the Technical Center Americas, our goal is to lead the industry in advanced battery systems and provide customers with quality engineered products that are safe, reliable, and optimized for their intended application.
Ilyas: Overall, we are working on many complex and engineered systems. Working with our colleagues in Guangzhou, our entire global team is focusing on quality and making our products even safer than what currently exists in the battery industry.

Avalanche effectIn cryptography, the avalanche effect refers to a desirable property of cryptographic algorithms, typically block ciphers and cryptographic hash functions. The avalanche effect is evident if, when an input is changed slightly (for example, flipping a single bit) the output changes significantly (eg, half the output bits flip). In the case of quality block ciphers, such a small change in either the key or the plaintext should cause a drastic change in the ciphertext. The actual term was first used by Horst Feistel, although the concept dates back to at least Shannon's diffusion.
If a block cipher or cryptographic hash function does not exhibit the avalanche effect to a significant degree, then it has poor randomization, and thus a cryptanalyst can make predictions about the input, being given only the output. This may be sufficient to partially or completely break the algorithm. It is thus not a desirable condition from the point of view of the designer of the cryptographic algorithm or device.
Constructing a cipher or hash to exhibit a substantial avalanche effect is one of the primary design objectives. This is why most block ciphers are product ciphers. It is also why hash functions have large data blocks. Both these features allow small changes to propagate rapidly through iterations of the algorithm, such that every bit of the output should depend on every bit of the input before the algorithm terminates.
In the image : The SHA1 hash function exhibits good avalanche effect. When a single bit is changed the hash sum becomes totally differen

The dominant sequence transduction models are based on complex recurrent or convolutional neural networks that include an encoder and a decoder. The best performing models also connect the encoder and decoder through an attention mechanism. We propose a new simple network architecture, the Transformer, based solely on attention mechanisms, dispensing with recurrence and convolutions entirely. Experiments on two machine translation tasks show these models to be superior in quality while being more parallelizable and requiring significantly less time to train. Our model achieves 28.4 BLEU on the WMT 2014 English-to-German translation task, improving over the existing best results, including ensembles, by over 2 BLEU. On the WMT 2014 English-to-French translation task, our model establishes a new single-model state-of-the-art BLEU score of 41.8 after training for 3.5 days on eight GPUs, a small fraction of the training costs of the best models from the literature. We show that the Transformer generalizes well to other tasks by applying it successfully to English constituency parsing both with large and limited training data.
Recurrent neural networks, long short-term memory and gated recurrent neural networks in particular, have been firmly established as state of the art approaches in sequence modeling and transduction problems such as language modeling and machine translation [35, 2, 5]. Numerous efforts have since continued to push the boundaries of recurrent language models and encoder-decoder architectures [38, 24, 15]. Recurrent models typically factor computation along the symbol positions of the input and output sequences. Aligning the positions to steps in computation time, they generate a sequence of hidden states ht, as a function of the previous hidden state ht−1 and the input for position t. This inherently sequential nature precludes parallelization within training examples, which becomes critical at longer sequence lengths, as memory constraints limit batching across examples. Recent work has achieved significant improvements in computational efficiency through factorization tricks and conditional computation , while also improving model performance in case of the latter. The fundamental constraint of sequential computation, however, remains. Attention mechanisms have become an integral part of compelling sequence modeling and transduction models in various tasks, allowing modeling of dependencies without regard to their distance in the input or output sequences [2, 19]. In all but a few cases , however, such attention mechanisms are used in conjunction with a recurrent network. In this work we propose the Transformer, a model architecture eschewing recurrence and instead relying entirely on an attention mechanism to draw global dependencies between input and output. The Transformer allows for significantly more parallelization and can reach a new state of the art in translation quality after being trained for as little as twelve hours on eight P100 GPUs.

The Transformer allows for significantly more parallelization and can reach a new state of the art in translation quality after being trained for as little as twelve hours on eight P100 GPUs.
The goal of reducing sequential computation also forms the foundation of the Extended Neural GPU , ByteNet and ConvS2S , all of which use convolutional neural networks as basic building block, computing hidden representations in parallel for all input and output positions. In these models, the number of operations required to relate signals from two arbitrary input or output positions grows in the distance between positions, linearly for ConvS2S and logarithmically for ByteNet. This makes it more difficult to learn dependencies between distant positions . In the Transformer this is reduced to a constant number of operations, albeit at the cost of reduced effective resolution due to averaging attention-weighted positions, an effect we counteract with Multi-Head Attention as described in section 3.2.
Self-attention, sometimes called intra-attention is an attention mechanism relating different positions of a single sequence in order to compute a representation of the sequence. Self-attention has been used successfully in a variety of tasks including reading comprehension, abstractive summarization, textual entailment and learning task-independent sentence representations [4, 27, 28, 22].
End-to-end memory networks are based on a recurrent attention mechanism instead of sequencealigned recurrence and have been shown to perform well on simple-language question answering and language modeling tasks .
To the best of our knowledge, however, the Transformer is the first transduction model relying entirely on self-attention to compute representations of its input and output without using sequencealigned RNNs or convolution. In the following sections, we will describe the Transformer, motivate self-attention and discuss its advantages over models such as [17, 18] and .
3. Model Architecture
Most competitive neural sequence transduction models have an encoder-decoder structure [5, 2, 35]. Here, the encoder maps an input sequence of symbol representations (x1,...,xn) to a sequence of continuous representations z = (z1,...,zn). Given z, the decoder then generates an output sequence (y1,...,ym) of symbols one element at a time. At each step the model is auto-regressive , consuming the previously generated symbols as additional input when generating the next.
The Transformer follows this overall architecture using stacked self-attention and point-wise, fully connected layers for both the encoder and decoder, shown in the left and right halves of Figure 1, respectively.
3.1 Encoder and Decoder Stacks
Encoder: The encoder is composed of a stack of N = 6 identical layers. Each layer has two sub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, positionwise fully connected feed-forward network. We employ a residual connection around each of the two sub-layers, followed by layer normalization . That is, the output of each sub-layer is LayerNorm(x + Sublayer(x)), where Sublayer(x) is the function implemented by the sub-layer itself. To facilitate these residual connections, all sub-layers in the model, as well as the embedding layers, produce outputs of dimension dmodel = 512.
Decoder: Thedecoder is also composed of a stack of N = 6 identical layers. In addition to the two sub-layers in each encoder layer, the decoder inserts a third sub-layer, which performs multi-head attention over the output of the encoder stack. Similar to the encoder, we employ residual connections around each of the sub-layers, followed by layer normalization. We also modify the self-attention sub-layer in the decoder stack to prevent positions from attending to subsequent positions. This masking, combined with fact that the output embeddings are offset by one position, ensures that the predictions for position i can depend only on the known outputs at positions less than i.
An attention function can be described as mapping a query and a set of key-value pairs to an output, where the query, keys, values, and output are all vectors. The output is computed as a weighted sum of the values, where the weight assigned to each value is computed by a compatibility function of the query with the corresponding key.
3.2.1 Scaled Dot-Product Attention
We call our particular attention 'Scaled Dot-Product Attention' (Figure 2). The input consists of queries and keys of dimension dk, and values of dimension dv. We compute the dot products of the query with all keys, divide each by √ dk, and apply a softmax function to obtain the weights on the values.
3.2.2 Multi-Head Attention
Instead of performing a single attention function with dmodel-dimensional keys, values and queries, we found it beneficial to linearly project the queries, keys and values h times with different, learned linear projections to dk, dk and dv dimensions, respectively. On each of these projected versions of queries, keys and values we then perform the attention function in parallel, yielding dv-dimensional output values. These are concatenated and once again projected, resulting in the final values, as depicted in Figure 2.
Multi-head attention allows the model to jointly attend to information from different representation subspaces at different positions. With a single attention head, averaging inhibits this.
Where the projections are parameter matrices W Qi ∈ R dmodel×dk , W Ki ∈ R dmodel×dk , WV i ∈ R dmodel×dv and WO ∈ R hdv×dmodel.
In this work we employ h = 8 parallel attention layers, or heads. For each of these we use dk = dv = dmodel/h = 64. Due to the reduced dimension of each head, the total computational cost is similar to that of single-head attention with full dimensionality.
3.2.3 Applications of Attention in our Model
The Transformer uses multi-head attention in three different ways: • In 'encoder-decoder attention' layers, the queries come from the previous decoder layer,and the memory keys and values come from the output of the encoder. This allows every position in the decoder to attend over all positions in the input sequence. This mimics the typical encoder-decoder attention mechanisms in sequence-to-sequence models such as [38, 2, 9]. • The encoder contains self-attention layers. In a self-attention layer all of the keys, values and queries come from the same place, in this case, the output of the previous layer in the encoder. Each position in the encoder can attend to all positions in the previous layer of the encoder. • Similarly, self-attention layers in the decoder allow each position in the decoder to attend to all positions in the decoder up to and including that position. We need to prevent leftward information flow in the decoder to preserve the auto-regressive property. We implement this inside of scaled dot-product attention by masking out (setting to −∞) all values in the input of the softmax which correspond to illegal connections. See Figure 2.
3.3 Position-wise Feed-Forward Networks
In addition to attention sub-layers, each of the layers in our encoder and decoder contains a fully connected feed-forward network, which is applied to each position separately and identically. This consists of two linear transformations with a ReLU activation in between.
While the linear transformations are the same across different positions, they use different parameters from layer to layer. Another way of describing this is as two convolutions with kernel size 1. The dimensionality of input and output is dmodel = 512, and the inner-layer has dimensionality df f = 2048.
3.4 Embeddings and Softmax
Similarly to other sequence transduction models, we use learned embeddings to convert the input tokens and output tokens to vectors of dimension dmodel. We also use the usual learned linear transformation and softmax function to convert the decoder output to predicted next-token probabilities. In our model, we share the same weight matrix between the two embedding layers and the pre-softmax linear transformation, similar to . In the embedding layers, we multiply those weights by √ dmodel.
3.5 Positional Encoding
Since our model contains no recurrence and no convolution, in order for the model to make use of the order of the sequence, we must inject some information about the relative or absolute position of the tokens in the sequence. To this end, we add 'positional encodings' to the input embeddings at the bottoms of the encoder and decoder stacks. The positional encodings have the same dimension dmodel as the embeddings, so that the two can be summed. There are many choices of positional encodings, learned and fixed .
In this work, we use sine and cosine functions of different frequencies: where pos is the position and i is the dimension. That is, each dimension of the positional encoding corresponds to a sinusoid. The wavelengths form a geometric progression from 2π to 10000 · 2π. We chose this function because we hypothesized it would allow the model to easily learn to attend by relative positions, since for any fixed offset k, P Epos+k can be represented as a linear function of P Epos.
We also experimented with using learned positional embeddings instead, and found that the two versions produced nearly identical results (see Table 3 row (E)). We chose the sinusoidal version because it may allow the model to extrapolate to sequence lengths longer than the ones encountered during training.
4 Why Self-Attention
In this section we compare various aspects of self-attention layers to the recurrent and convolutional layers commonly used for mapping one variable-length sequence of symbol representations (x1, ..., xn) to another sequence of equal length (z1, ..., zn), with xi, zi ∈ R d , such as a hidden layer in a typical sequence transduction encoder or decoder. Motivating our use of self-attention we consider three desiderata.
One is the total computational complexity per layer. Another is the amount of computation that can be parallelized, as measured by the minimum number of sequential operations required.
The third is the path length between long-range dependencies in the network. Learning long-range dependencies is a key challenge in many sequence transduction tasks. One key factor affecting the ability to learn such dependencies is the length of the paths forward and backward signals have to traverse in the network. The shorter these paths between any combination of positions in the input and output sequences, the easier it is to learn long-range dependencies . Hence we also compare the maximum path length between any two input and output positions in networks composed of the different layer types.
As noted in Table 1, a self-attention layer connects all positions with a constant number of sequentially executed operations, whereas a recurrent layer requires O(n) sequential operations. In terms of computational complexity, self-attention layers are faster than recurrent layers when the sequence length n is smaller than the representation dimensionality d, which is most often the case with sentence representations used by state-of-the-art models in machine translations, such as word-piece and byte-pair representations. To improve computational performance for tasks involving very long sequences, self-attention could be restricted to considering only a neighborhood of size r in the input sequence centered around the respective output position. This would increase the maximum path length to O(n/r). We plan to investigate this approach further in future work.
A single convolutional layer with kernel width k < n does not connect all pairs of input and output positions. Doing so requires a stack of O(n/k) convolutional layers in the case of contiguous kernels, or O(logk(n)) in the case of dilated convolutions , increasing the length of the longest paths between any two positions in the network. Convolutional layers are generally more expensive than recurrent layers, by a factor of k. Separable convolutions , however, decrease the complexity considerably, to O(k · n · d + n · d 2 ). Even with k = n, however, the complexity of a separable convolution is equal to the combination of a self-attention layer and a point-wise feed-forward layer, the approach we take in our model.
As side benefit, self-attention could yield more interpretable models. We inspect attention distributions from our models and present and discuss examples in the appendix. Not only do individual attention heads clearly learn to perform different tasks, many appear to exhibit behavior related to the syntactic and semantic structure of the sentences.
This section describes the training regime for our models.
5.1 Training Data and Batching
We trained on the standard WMT 2014 English-German dataset consisting of about 4.5 million sentence pairs. Sentences were encoded using byte-pair encoding , which has a shared sourcetarget vocabulary of about 37000 tokens. For English-French, we used the significantly larger WMT 2014 English-French dataset consisting of 36M sentences and split tokens into a 32000 word-piece vocabulary . Sentence pairs were batched together by approximate sequence length. Each training batch contained a set of sentence pairs containing approximately 25000 source tokens and 25000 target tokens.
5.2 Hardware and Schedule
We trained our models on one machine with 8 NVIDIA P100 GPUs. For our base models using the hyperparameters described throughout the paper, each training step took about 0.4 seconds. We trained the base models for a total of 100,000 steps or 12 hours. For our big models,(described on the bottom line of table 3), step time was 1.0 seconds. The big models were trained for 300,000 steps (3.5 days).
We used the Adam optimizer with β1 = 0.9, β2 = 0.98 and = 10−9. We varied the learning rate over the course of training, according to the formula:
This corresponds to increasing the learning rate linearly for the first warmup_steps training steps, and decreasing it thereafter proportionally to the inverse square root of the step number. We used warmup_steps = 4000.
We employ three types of regularization during training:
Residual Dropout We apply dropout to the output of each sub-layer, before it is added to the sub-layer input and normalized. In addition, we apply dropout to the sums of the embeddings and the positional encodings in both the encoder and decoder stacks. For the base model, we use a rate of Pdrop = 0.1.
Label Smoothing During training, we employed label smoothing of value ls = 0.1 . This hurts perplexity, as the model learns to be more unsure, but improves accuracy and BLEU score.
6.1 Machine Translation
On the WMT 2014 English-to-German translation task, the big transformer model (Transformer (big) in Table 2) outperforms the best previously reported models (including ensembles) by more than 2.0 BLEU, establishing a new state-of-the-art BLEU score of 28.4. The configuration of this model is listed in the bottom line of Table 3. Training took 3.5 days on 8 P100 GPUs. Even our base model surpasses all previously published models and ensembles, at a fraction of the training cost of any of the competitive models.
On the WMT 2014 English-to-French translation task, our big model achieves a BLEU score of 41.0, outperforming all of the previously published single models, at less than 1/4 the training cost of the previous state-of-the-art model. The Transformer (big) model trained for English-to-French used dropout rate Pdrop = 0.1, instead of 0.3.
For the base models, we used a single model obtained by averaging the last 5 checkpoints, which were written at 10-minute intervals. For the big models, we averaged the last 20 checkpoints. We used beam search with a beam size of 4 and length penalty α = 0.6 . These hyperparameters were chosen after experimentation on the development set. We set the maximum output length during inference to input length + 50, but terminate early when possible .
Table 2 summarizes our results and compares our translation quality and training costs to other model architectures from the literature. We estimate the number of floating point operations used to train a model by multiplying the training time, the number of GPUs used, and an estimate of the sustained single-precision floating-point capacity of each GPU 5.
6.2 Model Variations
To evaluate the importance of different components of the Transformer, we varied our base model in different ways, measuring the change in performance on English-to-German translation on the development set, newstest2013. We used beam search as described in the previous section, but no checkpoint averaging. We present these results in Table 3.
In Table 3 rows (A), we vary the number of attention heads and the attention key and value dimensions, keeping the amount of computation constant, as described in Section 3.2.2. While single-head attention is 0.9 BLEU worse than the best setting, quality also drops off with too many heads.
In Table 3 rows (B), we observe that reducing the attention key size dk hurts model quality. This suggests that determining compatibility is not easy and that a more sophisticated compatibility function than dot product may be beneficial. We further observe in rows (C) and (D) that, as expected, bigger models are better, and dropout is very helpful in avoiding over-fitting. In row (E) we replace our sinusoidal positional encoding with learned positional embeddings , and observe nearly identical results to the base model.
6.3 English Constituency Parsing
To evaluate if the Transformer can generalize to other tasks we performed experiments on English constituency parsing. This task presents specific challenges: the output is subject to strong structural constraints and is significantly longer than the input. Furthermore, RNN sequence-to-sequence models have not been able to attain state-of-the-art results in small-data regimes .
We trained a 4-layer transformer with dmodel = 1024 on the Wall Street Journal (WSJ) portion of the Penn Treebank , about 40K training sentences. We also trained it in a semi-supervised setting, using the larger high-confidence and BerkleyParser corpora from with approximately 17M sentences . We used a vocabulary of 16K tokens for the WSJ only setting and a vocabulary of 32K tokens for the semi-supervised setting.
We performed only a small number of experiments to select the dropout, both attention and residual (section 5.4), learning rates and beam size on the Section 22 development set, all other parameters remained unchanged from the English-to-German base translation model. During inference, we increased the maximum output length to input length + 300. We used a beam size of 21 and α = 0.3 for both WSJ only and the semi-supervised setting.
Our results in Table 4 show that despite the lack of task-specific tuning our model performs sur- prisingly well, yielding better results than all previously reported models with the exception of the Recurrent Neural Network Grammar .
In contrast to RNN sequence-to-sequence models , the Transformer outperforms the Berkeley- Parser even when training only on the WSJ training set of 40K sentences.
In this work, we presented the Transformer, the first sequence transduction model based entirely on attention, replacing the recurrent layers most commonly used in encoder-decoder architectures with multi-headed self-attention.
For translation tasks, the Transformer can be trained significantly faster than architectures based on recurrent or convolutional layers. On both WMT 2014 English-to-German and WMT 2014 English-to-French translation tasks, we achieve a new state of the art. In the former task our best model outperforms even all previously reported ensembles.
We are excited about the future of attention-based models and plan to apply them to other tasks. We plan to extend the Transformer to problems involving input and output modalities other than text and to investigate local, restricted attention mechanisms to efficiently handle large inputs and outputs such as images, audio and video. Making generation less sequential is another research goals of ours.
The code we used to train and evaluate our models is available at https://github.com/tensorflow/tensor2tensor.

Recently, more and more Malaysia SMEs started to devise innovative strategies in storing their accounting and financial information.
Businesses are rapidly switching from traditional on-premise accounting method to cloud accounting, with the aim to improve their financial departments’ accountability and transparency.
By taking advantage of cloud-based accounting software, businesses are less dependent on in-house hard drives when managing their accounting and finances. Leveraging the security of cloud-accounting, financial data’s security and accessibility are enhanced.
Traditional and cloud accounting comes with vastly different features. This post will discuss the key differences between these two different methods of recording, processing and storing financial data of a business.
Cloud vs. Traditional Accounting
Traditional accounting involves a dedicated in-house computer hard drive to store data and host the software. The on-premise accounting software is installed onto a desktop computer and is accessible through a desktop application. It does not require an internet connection, which is allow users without internet access to use it offline.
Cloud accounting has the same functionality as on-premise accounting software. Both function as software that records, processes, and stores financial details of a business.
However, with cloud accounting software, data is recorded, processed and stored on a remote server, eliminating the need for in-house computer hard drives. Users will need internet access and devices to operate and access the data.
On-premise software usually requires bigger upfront purchase, known as capital expenditure (CapEx) to a business. It involves up-front investment, responsibility and expertise to operate and maintain in-house computer hardware. When data size grows extensively, the initial invested storage system will need to be replaced or upgraded to accommodate more data. This will have a significant increase in business operations costs.
Conversely, cloud accounting does not require the investment of in-house computer hardware to store financial data. Cloud-based accounting software enables businesses to store data in the cloud and can be easily accessed via any mobile device. Although users have to pay a monthly or annual subscription, it is usually a cheaper option than adopting a traditional on-premise accounting software.
The financial data of the traditional accounting software are vulnerable to theft or physical damage, such as fires. It is a risk when data is stored on a computer’s hardware as it may be stolen or tampered by hackers.
Cloud accounting gives SMEs the accessibility of their financial data regardless of any situations that might affect the business. Virtual platform of cloud data storage is less vulnerable to physical damage.
The additional security levels making it difficult for a hacker to gain access to the data. In the case of any suspicious activity, a cloud accounting provider will be able to quickly detect and prevent a data breach.
Traditional accounting is deployed and maintained in-house at a physical office. Users can only gain access remotely with third-party support to access the solution and a mobile device. Cloud accounting software provides real-time data that can be accessed via the Internet anywhere at any time.
In other words, with a web-based interface device, your Finance personnel can access the software from home, while travelling, and from any location of their choice. The cloud keeps information updated in real-time,in a secure site, making it readily accessible.
As businesses grow, so does financial data size. SMEs using traditional accounting software will need to expand its in-house IT investment to meet the increasing storage size demand regularly. Each time the data size surpasses the limit, you will need to act fast and upgrade the hardware to accommodate the growth.
On the contrary, cloud accounting software is flexible and scalable such that it can accommodate business growth and needs.
5. Environment Friendliness
Traditional accounting requires users to print out financial information on paper, which is not environmentally friendly. Users can go paperless with cloud accounting since the data can be accessed electronically with a mobile device and internet access.
This makes the distribution of accounting information simple, efficient, and more economical compare to the traditional accounting method.
6. Cloud or Traditional Accounting the Future of Finance?
There is a growing trend for the adoption of cloud-based accounting software. Organisations that aims to implement a secure, cost-effective and scalable accounting software should consider adopting a cloud accounting solution.
As technology evolves rapidly to accommodate the ever-growing needs of businesses, even the Finance personnel needs to keep up with the technology trend and reap the benefits of adopting cloud-based software over traditional on-premise solutions.

New Zealand's Buzz Audio released its first commercial pro audio product in 1993. Owner/designer Tim Farrant's unique Class-A preamp was originally inspired by an ultra low-noise moving coil pickup circuit Farrant had developed during his broadcast engineering years. Lynn Fuston of 3D Audio was one of the first stateside engineers to extol the virtues of the hard-to-find Buzz MA preamp, which was later featured on his 3D Pre CD. Buzz Audio's handcrafted products are no longer hard to find, thanks to their well-established high-end reputation and worldwide distribution.
In 2000, Buzz introduced its ARC 1.1 analog recording channel ($3500) featuring a discrete mic preamp similar to that found in the MA series, a top-notch parametric equalizer, an optical compressor section drafted from Buzz' popular SOC 1.1 stereo optical compressor and a FET peak limiter. Outfitted with an immense array of controls and routing options, the ARC 1.1 is truly one of the most comprehensive and flexible recording channels available.
The Buzz Audio ARC 1.1 is essentially comprised of four separate sections: a microphone preamp, an instrument/line-level preamp, parametric EQ, and compressor/limiter. With the wealth of I/O connections provided, the ARC 1.1 can in fact be simultaneously used as four separate analog audio amplifiers/processors. On the rear panel are Mic Pre In and Mic Pre Direct Out jacks (XLR), Line In and Line Loop Out jacks (XLR), and a line-level Main Out jack (XLR). A front-panel high-impedance instrument jack (TS 1/4-inch) is also provided. The Line Loop connection provides a hard-wired copy of the signal at the Line In jack for daisy-chain/parallel-path purposes. Also on the rear panel are EQ In and EQ Out jacks (XLR), and Comp In and Comp Out jacks (XLR), as well as a Sidechain Insert jack (TRS 1/4-inch) and a Compressor Link jack (TS 1/4-inch) for stereo operation of two ARC 1.1 units.
The front panel of the ARC 1.1 is logically divided into three main sections: input/output amplification, parametric equalizer, and optical compressor/FET limiter. The mic preamp section features a Mic Gain knob (+9 to +50 dB of gain), a +15 dB gain switch, a +48V phantom power switch (with soft-start circuit) and a continuously variable 220 ohm to 5.5 k-ohm Mic Load control. The line amp input section features a Line Gain knob (0 to +40 dB of gain), -10 dB line gain switch, and a Balanced/Unbalanced toggle switch that selects between the rear-panel XLR line input and the front panel 1/4-inch instrument input.
The last part of the front-panel I/O amplifier section provides the controls that pertain to the signal sent to the rear-panel Main Out XLR jack. These controls are comprised of a Mic/Line selector switch, Output Attenuation/Gain knob (providing an additional 10 dB of gain if desired), a combo normal phase/mute/reverse phase switch, and a main path/sidechain path monitor switch. Also included in this section is a Clean/Tranny switch for switching in a custom-made audio transformer into the main path for added harmonic distortion and color.
The EQ section consists of a sweepable high-pass filter, semi fixed-frequency high and low shelving filters, and two bands of fully parametric equalization. Each of the five bands features a three-position In (main path)/Ext (external rear connection)/SC (sidechain path) routing toggle switch - see In Use for more on the ARC 1.1 routing options. The high-pass filter attenuates at 12 dB/octave, and features a variable cut-off frequency range (3 dB down) of 25 to 450 Hz. The high shelf provides up to 17 dB of boost or cut in two modes: Broad or Tight. As its name implies, the Broad setting is a wide, gradual curve that starts at around 1 kHz and flattens out around 20 kHz. The Tight setting is a much steeper shelf that rises significantly starting around 4 kHz and flattens out around 20 kHz. The real inductor-based low shelf provides up to 17 dB of boost or cut in a fairly gentle curve at a 60 or 120 Hz turnover frequency. The two fully parametric bands provide for up to 16 dB of boost or cut at continuously variable center frequencies of 30 Hz to 7 kHz (Band 1) and 160 Hz to 34 kHz (Band 2) at bandwidths ranging from .25 to 1.7 octaves.
The final section on the front panel includes the ARC's compressor and limiter. The optical compressor features a Drive control (aka threshold), a four-position Ratio control (2:1, 5:1, 10:1, 20:1), a three-position Attack switch (slow, fast, auto), a six-position Release control (1, 2, 4, 8 and 16 x 100mS, auto) and a Comp Makeup gain control (0 to +15 dB). The compressor also features a dedicated 12-step LED gain-reduction meter, a Pre-EQ/Post-EQ/EXT path selector switch and a Mono/Stereo link switch.
The peak limiter includes a 0 to +20 dB threshold knob, a three-position Release switch (Fast-100mS, Medium-750mS, Slow-2000mS), a three-position routing switch (In, Out, Ext) and a Limit operational LED. Rounding out the front-panel controls are a 12-step LED level meter plus Over LED, and a mains power switch with LED. The level meter can be switched to monitor mic or line input level in the main path (as determined by the master mic/line selector switch), the main path output level, or switched off.
From both a design and use standpoint, this is an engineer's recording channel: it is designed by someone with an obvious passion for audio circuitry and all the possible options afforded at each stage in the audio path, and it is best employed by recording engineers who appreciate being trusted with such a full range of control. Despite its 18 knobs, 24 toggle switches and 12 I/O jacks, I can picture Buzz' Tim Farrant sweating over which features he would have to cut out to fit the single-channel ARC 1.1 into its 2-rack space chassis. The first thing I did when I received the ARC 1.1 for review was to wire all its rear-panel jacks to my patch bay to maximize its routing potential. But before I get into the ARC's routing flexibility, I want to talk about how it sounds. In a word, fantastic.
The preamp is extremely quiet and pure, and its 15 dB gain switch (plus additional 10 dB available at the output stage) provides plenty of gain for even the quietest sources. The continuously variable mic impedance knob always enabled an excellent match with my favorite ribbon, condenser and tube mics (as well as an odd-ball assortment of dynamics). The not-so-subtle "Tranny" transformer switch added yet another colorful dimension to the palette, and its placement before the output gain stage allowed me to drive the transformer with the input stage to varying degrees while compensating for level at the output.
The EQ and compressor sections are as thoughtful and musical as the preamp section. The EQ section's two parametric mid bands can craft subtle or surgical changes across the entire audio spectrum, and the more limited control of the shelving and high-pass filters proved to be the perfect tools to effect quick, overall changes.
The optical compressor section also yielded excellent results, most notably in its ability to intuitively track bass and vocal performances with nary a hint of pumping. In one of the most brilliant strokes of circuit-design creativity, the ARC 1.1 essentially features three discreet audio paths to which individual sections (and individual EQ bands) can be routed: main, external and sidechain. It is by virtue of this flexible scheme and the inclusion of dedicated I/O per section that this single unit can be used to independently amplify and process up to four separate sources. In the short space I have left, I will attempt a reasonable explanation here, but I highly recommend checking out the well-written manual found on the Buzz website (www.buzzaudio.com) for in-depth info.
The main path is for the most "normal" use of the ARC 1.1 - i.e. as an all-in-one recording strip. This path routes the mic or line source into the EQ then compressor (or compressor then EQ) sections and out through the output gain stage and meter to the main output jack. Choosing the external path sends the compressor and/or limiter output signal to the rear-panel compressor output jack, and likewise, the selected EQ bands to the rear-panel EQ output jack. Setting any or all of the EQ bands to SC puts that signal into the compressor sidechain circuit, allowing frequency-dependent operation of the compressor.
In an extreme example of the ARC's flexibility, one could separately use the Buzz mic preamp via its direct I/O, the line or instrument input (with, say, the "Tranny" option, the high-pass filter and a band of EQ plus the peak limiter) through the main path, patch another source in and out of (any or all of) the remaining bands of the EQ section, and a fourth source in and out of the optical compressor. If you really want to get crazy, you can also send one of the bands of EQ to the compressor sidechain to have one instrument affecting the compression characteristic of the other! Of course you could also do that without sacrificing an EQ band by making use of the external compressor sidechain insert jack.
For me, a more common simultaneous scenario was to use the mic preamp patched into the EQ input (with the HPF set to Ext.) then back out into the compressor input and out to tape, alongside a DI on the line input routed through via the main path into the EQ and peak limiter and through the main out (with "Tranny"!) to tape. The one ommission on the ARC 1.1 - believe it or not - is its lack of individual EQ band on/off switches. In most cases, this is not a problem since bands can be taken out of circuit by simply setting them to S/C or Ext (assuming you are not using the EQ I/O). The only possible time this would be a problem would be if you have an EQ setting you want to turn on and off for A/B purposes and both the sidechain and the external EQ I/O are in use.
The Buzz Audio ARC 1.1 is by no means designed for dumbed-down, streamlined set-and-leave use, but neither is it unintuitive or difficult to operate. At its most basic operational level, the user will be rewarded with an excellent-sounding preamp, musically intuitive EQ and a smooth optical compressor section - everything one could want in a top-notch recording channel. For those with a more in-depth engineering sense (or those wanting to learn), the ARC 1.1 has the uncanny ability to instill in the user some of the same passion for audio creativity that so obviously went into its design.

The winners of this year's Nobel Prize in Physics were announced today, and while the award hasn't gone to my first choice, Vera Rubin (or any astrophysicist for that matter), it has gone to a trio of very worthy winners. The winners are Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura for their work in the development of blue LEDs (light emitting diodes).
Why is this so important? Well, it is thought that about 20-30% of the electricity in the world is consumed in electrical lighting, and since LEDs are about 10 times more energy efficient and last about 100 times longer than traditional incandescent light bulbs, the worldwide adoption of LEDs will significantly reduce the world's energy consumption (and therefore its carbon dioxide emission).
So while this wasn't my first choice for the Nobel Prize, it is surely a deserved award!

Power supply manufacturer Seasonic has a nifty tool available (in open beta) on its website right now: a wattage calculator, which lets you punch in the specs for your planned PC build and receive suggestions for which PSU is best suited for your components. It’s a helpful tool for anyone building a new PC, but it may have also just leaked fresh information regarding AMD’s upcoming GPU releases.
The tool requires you to select your CPU and GPU from a drop-down menu, the latter of which is now listing three new Radeon graphics cards: the RX 7700 XT, the RX 7800 XT, and the RX 7900 XT. Although we know that AMD is planning to launch new GPUs using the RDNA 3 architecture to compete with Nvidia’s RTX 4000 series, other information is thin on the ground right now.
Plugging these GPUs into Seasonic’s wattage calculator gives us a suggestion of a 650W power supply for the 7700 XT, and a 750W one for the 7800 XT and 7900 XT. These are essentially the same as the power requirements of their RX 6000-series counterparts, and the Seasonic website also recommends power supplies with standard 8+6-pin PCIe connectors, rather than the new 16-pin connectors.
It’s unclear at this point whether these power requirements are legitimate or merely placeholders that Seasonic has implemented, but these figures are entirely reasonable and within our expectations. It also does seem to suggest that the first round of 7000-series Radeon GPUs will feature these three cards, with AMD potentially waiting to release the lower-end GPUs and bypassing non-XT variants altogether.
Analysis: What do these power specs mean for consumers?
If accurate, these leaked power requirements are very good news for the average PC-builder. If the 7000-series Radeon cards are able to offer improved performance over their 6000-series equivalents without a significant rise in TDP, they’ll be very attractive to PC gamers looking to upgrade.
It’ll be very convenient if AMD’s new GPUs continue to use 8+6-pin connectors for power delivery too, since you won’t need to upgrade your PSU to install a new GPU in your system. The new 16-pin connector is only available on select power supplies at this point, and it looks like Intel’s new discrete GPUs will be using the 8+6 configuration too.
Still, such leaks should be taken with a grain of salt. I wouldn’t be overly surprised if the high-end RX 7900 XT does require a 16-pin connector, given that it’ll need to compete with both Intel’s new GPUs and Nvidia’s imminent RTX 4000 cards (which will doubtless include an RTX 4090 flagship). Pricing is also still completely unknown, with some sources speculating that the RX 7900 XT could cost as much as $2,000.

In this Part 2 of a two-part video series, we will follow the +325VDC current as it flows to the tube plates. Then we will study the nature of the guitar input signal, and apply this signal to the grids of the tubes, following it through several stages of amplification until it reaches the speaker voice coil. The presentation is primarily conversational rather than technical and utilizes analogies and basic language to explain the chain of events that occur within the amplifier circuit.
Components such as coupling capacitors, output transformers, speaker voice coils, etc. will be encountered along the way, and will be discussed, as will concepts such as plate voltage, plate current, and output tube biasing.
If you enjoy watching videos featuring classic vintage tube amps, jukeboxes, exotic electromechanical devices, and simple, basic technical presentations, then please subscribe to my channel. You will gain immediate access to almost 100 videos, and (if you activate the service) you will be notified each time a new video is posted.

TLDR; Weak CAPTCHA services utilized on the internet can be programmatically solved with a fairly high success rate.
A lot of firms, including mine, have begun to recommended CAPTCHA’s be used on all web forms which feed into existing business processes (registration pages, contact pages, etc). This recommendation can be a double edged sword, because there are still several CAPTCHA services that utilize weak CAPTCHA’s, which can be readily decoded with modern image analysis techniques. That being said several individuals have asked if there is a systematic way to test the strength of a given CAPTCHA, to determine weather it’s weak or not.
There are two major methodologies currently being widely used to decode weak CAPTCHA’s. The first technique is to remove the noise from CAPTCHA images by reversing the programmatic functions, used to add visual abstractions. Then simply comparing each character to a set of known sample characters. This method relays heavily on evaluating each weak CAPTCHA service offering and creating reliable function sets to solve individual CAPTCHA’s. The best tool for using this technique to test for known weak CAPTCHA types is pwntcha.
The second methodology uses vector based image analysis to compare each pixels location to the expected location given, each possible character. After consolidating all of these pixel location checks, each possible character is ranked based on its probability of being correct. The success of this method relays heavily on the use of a reference font, thus if the reference font and the CAPTCHA’s font are distantly different the analysis won’t go well. The best freely available tool I’ve found using this technique to test the strength of CAPTCHA’s is captcha-decoder.
How to use
Unfortunately almost every implementation of CAPTCHA’s is going to be different enough to make web scrapping a sample set of CAPTCHA images difficult. Thus the first step is always going to be downloading three to five CAPTCHA images for testing.
Then we can run each image through pwntcha and see if it can identify the image as a known weak CAPTCHA type.
Test run using Paypal’s known weak CAPTCHA samples 100/100
Test run of vBullentin’s known weak CAPTCHA samples 100/100
Last we can run captcha-decoder on each of the sample images to try and get an idea if vector based analysis is going to be successful. You will have to use your best judgment once you receive the results to determine if the risk is high enough to create an issue. Generally if all the correct letters are guessed with over 70% confidence the CAPTCHA should be considered weak. However an organization may believe 70% is too high and may only have a much lower tolerance.
How to Install Arduino Backdoors within Modern Keyboards
TLDR; It is very possible to place a Teensy Arduino within modern keyboards and mice as a hardware backdoors in order to implant a Trojan on a targets computer.
Warning #1: Please understand that working with electrical equipment and components is inherently dangerous. Burns, shocks, and electrical fires are fairly common when attempting to manipulate commercial/consumer grade electronics.
Warning #2: The author of this article claims no responsibility for personal harm or damage to personal property. This information is provided as is and without merit or warranty.
Some of our tougher targets have gotten very good at detecting and shutting down our normal social engineering attack vectors. In fact several are now able to systematically detect and shutdown our classic, emails, phone calls, and media drops Trojans. Once a client has established a strong defense against our standard attack vectors we are at somewhat of a loss as to how to approach social engineering. This has forced our team to come up with new and innovative ways to get in and get access.
My innovative idea is a new twist on an older poly idea, the hardware backdoor. Where one actually solders malicious hardware into another hardware system to gain access. This is normally done to subvert security controls such as drive encryption or to maintain access to a computing system.
However I’m not the NSA, nor am I am electrical engineering, so instead of attempting to compromise an entire computing system, I set out to simply place a hardware device within a keyboard. The idea being that I could purchase a few higher end keyboards, backdoor them, and send them out as gifts to targeted individuals. I quickly discovered a cheap Arduino based keyboard controller called Teensy and set out on my quest.
After conducting some further research, I quickly realized why we don’t see this attack vector being used in the wild. I won’t go into complete detail on every discovered issue, but a brief list is as follows.
Most keyboards are now soft-key using two sheets of conductive plastic and a rubber boot to trigger a key-press.
Space is normally very limited and many keyboard types such as soft-key don’t handle added pressure well.
Creating a custom keyboard or even a DYI 60% (uses a modern PCB with built in controller), is very time consuming and expensive.
Keyboards now use proprietary layouts and controllers which make tampering with them difficult.
Almost all mechanical and soft-touch keyboards are now made with a dual or triple layer PCB, adding literally layers of complexity.
Simply splicing a device in the middle of the USB connection creates added complexity by requiring the handling of serial timing, errors, and interrupters.
Needless to say, I had to simplify my plan even further. So I narrowed my focus to Cherry MX mechanical keyboards with built in USB hub ports. Since the Cherry MX keys are extremely sought after and conveniently take up quite a bit of space, it should be fairly easy to tuck the quarter sized Teensy into some free space. Additionally, if there is already a USB hub built into the keyboard controller, I can simply add the device inside by soldering the Teensy directly to the internal leads.
Note: Using this method is quick and dirty. It will take over said USB ports communication path and power channel. If another USB is plugged into the target port, best case scenario one of the two devices doesn’t power up, worst case you have yourself a nice little electrical fire. As such I would recommend clipping the pins or putting a plastic cover over the original USB hole.
The last step is simply programing the Teensy, which is somewhat out of the scope of this article, due to complexity and lack of one size fits all payload. However the Social Engineering Toolkit (SET) contains a great of code to use as a starting point (linked bellow in references).
Note: Creating payloads requires the Arduino IDE with the Teensy library’s, modules, and extensions installed. You also require direct access to the Teensy via a micro-USB cable. Meaning VMware and the aforementioned hub setup should be avoided when compiling and uploading your payload.
Unfortunately the project for which I backdoored the Razer Blackwidow Ultimate had a fairly tight time table and did not allow for me to get very good photos. Nonetheless, I’ve included two of the better photos I have of the Blackwidow, to show that the same techniques can be successfully applied to modern keyboards as well.
Showing the completed build out of the Blackwidow with the Micro-USB attached to the single set of USB leads on the builtin controller.
This photo shows the limited space within the Blackwidow shell. In fact the cable as to be flush with the PCB corner in order to get the case to close. Then the Teensy itself has to be firmly placed in an angle between the row of F-keys and the back wall of the lower plastic frame. In future builds I’ll likely just shave/grind down the plastic frame and or PCB to make things fit more precisely.
About the Teensy Arduino
The Teensy is a quarter sized fully programmable keyboard controller based on the open Arduino hardware standards. The Teensy allows for complete control over the keyboard, mouse, and touch screen via pseudo C code. It allows for roughly 30,000 lines of compiled code and roughly 60MB of on board storage, so we can accomplish quite a bit. It also is designed and built in such a way to allow for it to be easily extensible by offering 54 leads/pins for project flexibility. The Teensy also operates at as low as 3.3 volts with .25 amps and as high as 6 volts with 1 amp, making it robust enough to be connected directly to a powered or unpowered USB hub/port within a keyboard or mouse.
A Simplified How To Guide
The photos below are of a generic HP console keyboard being backdoored. This is simply because I happened to have it laying around and it awarded me the time and error tolerance required to provide detailed photos and guidance. As stated, they same steps can generally be followed on a Blackwidow, however the components are quite a bit smaller and space is more limited, making it much harder to work with and display.
The first step is fairly simple, just take all the screws out of the back of the keyboard and pop the back cover off. Just be very careful to not damage any of the components or parts, including the tiny plastic tabs that normally seal the edges.
Next identify the USB port to target by considering surrounding space and ease of access. Here I’ve chosen to use the forward set of pins since there is more space and avoids the lower screw hole/ground
Next review the orientation and contacts of the female USB port to identify each lead against the USB standard. In this case the leads were on the lower portion of separator within the female USB port.These leads are just copper or aluminum that normally just have a 90 degree bend and connects straight down on the bottom of the board. In my case the leads simply passed straight through to the bottom USB port and were arranged in order from 1 to 4.
Next cut a micro USB cable to the needed length, remove the shielding, remove the netting, untwist the wires, and strip the ends of each of the four wires. Then be sure to cut away all of the excess shielding and netting, so it doesn’t get in the way going forward.
In my case, each of the striped wires had dozens of tiny aluminum wires within them, instead of a single copper core. This can make keeping these wires together while soldering really annoying, but can also be used to your advantage by soldering the smaller wires together into a nice single bundle. The bundle makes soldering easier and the excess solder soaked up by the wires, normal removed to need to add additional solder when connecting the wires.
Once all the bundles are complete, they should all be soldered together and have a small ball on the ends. The ball on the end is used to quickly heat up each joint with the soldering iron and to quickly set the wire on the lead by holding it in place for a few seconds. If you are sensitive to heat, you may want to use some metal clips or helping hands.
Be sure to double and triple check your solders against the USB wiring standard before testing, to avoid electrical fires.
Note: For those who may not know how to solder or need a refresher, I’ve included a info-graphic bellow that I think provides enough information to hit the group running.
Once all the wires are soldered into place, simply make sure none of the surrounding leads are jumped or damaged and then run some tests to verify the system works as intended. In my case I had an issue with the ground initially and the Teensy was not receiving power, so always test thoroughly.
Once everything tests okay, find the best placement for the Teensy and secure the cable, Teensy, and solders with hot glue and/or electrical tape. In my case I had originally wanted to place my Teensy on the left side of the USB but the cable was too large for the sharp corner. Instead I carefully adjusted the cable over to the right under the USB hub cable.
Once the Teensy and cable are secured in place, run some additional tests, to ensure nothing was damage then button everything up. Just note as stated earlier, you will need to remove the Teensy in order to properly connect it directly for development of your payload.
The next image shows the Teensy hidden away under the USB hub cable. Just be careful about placing the Teensy on its face, as seen here, due to the payload launch button on the face. If its compressed it will continuously fire the payload until power is removed or all of the Teensy’s resources are locked up.
As always I want to include references as a massive thank you to the community at large. I couldn’t have done this without their help, support, and knowledge.

John Deere’s new generation StarFire 6000 satellite receiver has been designed to set new standards in operational accuracy and signal uptime. As the successor to the StarFire 3000 receiver, the StarFire 6000 features an improved antenna and the latest in global navigation satellite system (GNSS) signal processing technology. A new optional locking device for better theft protection is also available.
Russian GLONASS satellite compatibility and the proven integrated terrain compensation module (TCM) remain as standard. In addition, the new receiver is available with an improved, free SF1 correction signal (+/-15cm, reduced from 23cm), an all-new SF3 signal with +/-3cm pass to pass accuracy and a number of major RTK (+/-2.5cm) innovations.
The StarFire 6000 features a new ‘triple StarFire accuracy’ mode, which now tracks three satellites in parallel instead of one. This provides three times more signal stability in shady conditions and the potential to switch to a back-up satellite 80 per cent more quickly than the previous model.
Acquisition of the new SF3 correction signal is also three to four times quicker, so users spend less time waiting for the receiver to achieve full accuracy and can get high-precision jobs started even faster.
With in-season repeatability up to nine months, the SF3 signal can be relied on to prevent guidance line drift when operating in long fields, skipping passes or when using AutoTrac for multiple jobs throughout the growing season. Examples include the creation of AutoTrac guidance lines during drilling and planting, and the use of the same lines to complete subsequent jobs such as fertilising, post-emergence spraying and harvesting.
RTK customers can now benefit from a longer RTK Extend mode of up to 14 days. If the line of sight to the base station or the mobile network connection is lost, users can maintain full accuracy and repeatability for up to two weeks, even outside the RTK network.
A new John Deere 4G LTE mobile RTK modem with two high performance antennae not only supports the latest 4G LTE (long-term evolution) mobile communication standard, but also continues to support 3G and 2G standards to provide the best possible network coverage and signal stability. Customers also have a free choice of SIM card and correction signal provider. Being entirely self-contained, the complete StarFire receiver system can easily be moved from machine to machine in less than a minute.
The new, John Deere mobile RTK signal is compatible not only with the John Deere 4G LTE mobile RTK modem but also with the JDLink modular telematics gateway (MTG) controller. With this uniquely integrated solution, customers don’t need to invest in a separate modem and SIM card with a data plan. The whole system is provided from one source, making it easy to buy, set up and service.

We present a sampling-based framework for multi-robot motion planning which incorporates an implicit representation of a roadmap with a novel approach for pathfinding in geometrically embedded graphs.
Our pathfinding algorithm, discrete-RRT (dRRT), is an adaption of the celebrated RRT algorithm, for the discrete case of a graph. By rapidly exploring the high-dimensional configuration space represented by the implicit roadmap, dRRT is able to reach subproblems where minimal coordination between the robots is required. Integrating the implicit representation of the roadmap, the dRRT algorithm, and techniques that are tailored for such subproblems on the implicit roadmap allows us to solve multi-robot problems while exploring only a small portion of the configuration space.
We demonstrate our approach experimentally on scenarios of up to 60 degrees of freedom where our algorithm is faster by a factor of at least ten when compared to existing algorithms that we are aware of.

Proteus achieves fast response times and efficient utilization of the available hardware resources. It encapsulates device heterogeneity to enable seamless orchestration across CPUs and GPUs.
Proteus is a database engine designed for today's heterogeneous environments. Proteus adapts to variable data, hardware and workloads through a combination of GPU acceleration, data virtualization, and adaptive scheduling.
The challenge: Heterogeneity
Data, hardware, and workloads are increasingly heterogeneous, challenging existing system designs and slowing down data scientists' exploration cycles.
Proteus uses heterogeneity to unlock optimization opportunities, delivering accelerated operational analytics and reducing the data-to-insights time.
Data scientists rely on a wide variety of heterogeneous datasets to gain insights. The different data models and formats pose a significant challenge in performing analysis over diverse datasets.
Proteus virtualizes the data to provide a uniform operational model while allowing for just-in-time specialization to the data models and formats at hand.
The modern hardware landscape expands beyond CPU-only servers to meet the computational demands. Modern servers have multiple hardware accelerators relying on software exploiting the available hardware resources, challenging existing systems that depend on hardware uniformity, and continuous hardware advances on CPUs.
Proteus exploits accelerator-level parallelism to reduce query response times by orchestrating query execution in multi-CPU, multi-GPU servers and using just-in-time compilation for smoother cross-device operator support.
The velocity of modern workloads generates vast amounts of data that need to be quickly ingested to allow timely business intelligence, pushing the limits of existing static resource allocation schemes for operational analytics.
Proteus exploits workload irregularities to deliver fast insights, while it exploits accelerator-level parallelism to increase workload isolation.
Proteus customizes itself on-demand to the data formats and hardware. It uses LLVM-based code generation to JIT (just-in-time) provide highly-optimized specialized engines per query.
Proteus schedules concurrent OLTP and OLAP based on the amount of fresh data queried by OLAP, and adapts data access paths, compute affinities and snapshot granularity across the OLAP & OLTP engines.
Proteus enables efficient and online data exploration through JIT data summaries. It uses hardware-conscious approximation operators designed for high-bandwidth data processing to unlock interactive data insights.
Proteus minimizes software-level interference across the transactional and analytical engines. It uses the hardware isolation between CPUs and GPUs to bound interference across workloads.
Proteus intelligently caches input data for fast analytics on disk-resident data. Through query- and execution-awareness, it distributes the in-memory space across input data to maximize the overall query speedups.
As the data volume grows, reducing the query execution times remains an elusive goal. While approximate query processing (AQP) techniques present a principled method to trade off accuracy for faster queries in analytics, the sample creation is often considered a second-class citizen. Modern analytical engines optimized for high-bandwidth media and multi-core architectures only exacerbate existing inefficiencies, resulting in prohibitive query-time online sampling and longer preprocessing times in offline AQP systems.
We demonstrate that the sampling operators can be practical in modern scale-up analytical systems. First, we evaluate three common sampling methods, identify algorithmic bottlenecks, and propose hardware-conscious optimizations. Second, we reduce the performance penalties of the added processing and sample materialization through system-aware operator design and compare the sample creation time to the matching relational operators of an in-memory JIT-compiled engine. The cost of data reduction with materialization is up to 2.5x of the equivalent group-by in the case of stratified sampling and virtually free (∼1x) for reasonable sample sizes of other strategies. As query processing starts to dominate the execution time, the gap between online and offline AQP methods diminishes.
Analytical engines rely on in-memory caching to avoid disk accesses and provide timely responses by keeping the most frequently accessed data in memory. Purely frequency- & time-based caching decisions, however, are a proxy of the expected query execution speedup only when disk accesses are significantly slower than in-memory query processing. On the other hand, fast storage offers loading times that approach or even outperform fully in-memory query execution response times, rendering purely frequency-based statistics incapable of capturing impact of a caching decision on query execution. For example, caching the input of a frequent query that spends most of its time processing joins is less beneficial than caching a page for a slightly less frequent but scan-heavy query. As a result, existing caching policies waste valuable memory space to cache input data that offer little-to-no acceleration for analytics.
This paper proposes HPCache, a buffer management policy that enables fast analytics on high-bandwidth storage by efficiently using the available in-memory space. HPCache caches data based on their speedup potential instead of relying on frequency-based statistics. We show that, with fast storage, the benefit of in-memory caching varies significantly across queries; therefore, we quantify the efficiency of caching decisions and formulate an optimization problem. We implement HPCache in Proteus and show that i) estimating speedup potential improves memory space utilization, and ii) simple runtime statistics suffice to infer speedup expectations. We show that HPCache achieves up to 12% faster query execution over state-of-the-art caching policies, or 75% less in-memory cache footprint without deteriorating query performance. Overall, HPCache enables efficient use of the in-memory space for input caching in the presence of fast storage, without any requirement for workload predictions.
GPUs are becoming increasingly popular in large scale data center installations due to their strong, embarrassingly parallel, processing capabilities. Data management systems are riding the wave by using GPUs to accelerate query execution, mainly for analytical workloads. However, this acceleration comes at the price of a slow interconnect which imposes strong restrictions in bandwidth and latency when bringing data from the main memory to the GPU for processing. The related research in data management systems mostly relies on late materialization and data sharing to mitigate the overheads introduced by slow interconnects even in the standard CPU processing case. Finally, workload trends move beyond analytical to fresh data processing, typically referred to as Hybrid Transactional and Analytical Processing (HTAP).
Therefore, we experience an evolution in three different axes: interconnect technology, GPU architecture, and workload characteristics. In this paper, we break the evolution of the technological landscape into steps and we study the applicability and performance of late materialization and data sharing in each one of them. We demonstrate that the standard PCIe interconnect substantially limits the performance of state-of-the-art GPUs and we propose a hybrid materialization approach which combines eager with lazy data transfers. Further, we show that the wide gap between GPU and PCIe throughput can be bridged through efficient data sharing techniques. Finally, we provide an H2TAP system design which removes software-level interference and we show that the interference in the memory bus is minimal, allowing data transfer optimizations as in OLAP workloads.
Modern Hybrid Transactional/Analytical Processing (HTAP) systems use an integrated data processing engine that performs analytics on fresh data, which are ingested from a transactional engine. HTAP systems typically consider data freshness at design time, and are optimized for a fixed range of freshness requirements, addressed at a performance cost for either OLTP or OLAP. The data freshness and the performance requirements of both engines, however, may vary with the workload.
We approach HTAP as a scheduling problem, addressed at runtime through elastic resource management. We model an HTAP system as a set of three individual engines: an OLTP, an OLAP and a Resource and Data Exchange (RDE) engine. We devise a scheduling algorithm which traverses the HTAP design spectrum through elastic resource management, to meet the workload data freshness requirements. We propose an in-memory system design which is non-intrusive to the current state-of-art OLTP and OLAP engines, and we use it to evaluate the performance of our approach. Our evaluation shows that the performance benefit of our system for OLAP queries increases over time, reaching up to 50% compared to static schedules for 100 query sequences, while maintaining a small, and controlled, drop in the OLTP throughput.
Modern server hardware is increasingly heterogeneous as hardware accelerators, such as GPUs, are used together with multicore CPUs to meet the computational demands of modern data analytics workloads. Unfortunately, query parallelization techniques used by analytical database engines are designed for homogeneous multicore servers, where query plans are parallelized across CPUs to process data stored in cache coherent shared memory. Thus, these techniques are unable to fully exploit available heterogeneous hardware, where one needs to exploit task-parallelism of CPUs and data-parallelism of GPUs for processing data stored in a deep, noncache-coherent memory hierarchy with widely varying access latencies and bandwidth.
In this paper, we introduce HetExchange-a parallel query execution framework that encapsulates the heterogeneous parallelism of modern multi-CPU-multi-GPU servers and enables the parallelization of (pre-)existing sequential relational operators. In contrast to the interpreted nature of traditional Exchange, HetExchange is designed to be used in conjunction with JIT compiled engines in order to allow a tight integration with the proposed operators and generation of efficient code for heterogeneous hardware. We validate the applicability and efficiency of our design by building a prototype that can operate over both CPUs and GPUs, and enables its operators to be parallelism- and data-location-agnostic. In doing so, we show that efficiently exploiting CPU-GPU parallelism can provide 2.8x and 6.4x improvement in performance compared to state-of-the-art CPU-based and GPU-based DBMS.
In the last years, modern servers are adopting hardware accelerators, such as GPUs, in order to improve their power efficiency and computational capacity. Modern analytical query processing engines are highly optimized for multi-core multi-CPU query execution, but lack the necessary abstractions to support concurrent hardware-conscious query execution over multiple heterogeneous devices and exploit the available accelerators.
This work presents a Heterogeneity-conscious Analytical query Processing Engine (HAPE), a blueprint for hardware-conscious analytical engines for efficient and concurrent multi-CPU multi-GPU query execution. HAPE decomposes query execution on heterogeneous hardware into, 1) efficient single-device and 2) concurrent multi-device query execution. It uses hardware-conscious algorithms designed for single-device execution and combines them into efficient intra-device hardware-conscious execution modules, via code generation. HAPE combines these modules to achieve multi-device execution by handling data and control transfers.
We validate our design by building a prototype and evaluating its performance using radix-join co-processing and the TPC-H benchmark. We show that it achieves up to 10x and 3.5x speed-up on the radix-join against CPU and GPU alternatives, respectively, and 1.6x-8x against state-of-the-art CPU- and GPU-based commercial DBMSs on the selected TPC-H queries.
Industry and academia are continuously becoming more data-driven and data-intensive, relying on the analysis of a wide variety of heterogeneous datasets to gain insights. The different data models and formats pose a significant challenge on performing analysis over a combination of diverse datasets. Serving all queries using a single, general-purpose query engine is slow. On the other hand, using a specialized engine for each heterogeneous dataset increases complexity: queries touching a combination of datasets require an integration layer over the different engines.
This paper presents a system design that natively supports heterogeneous data formats and also minimizes query execution times. For multi-format support, the design uses an expressive query algebra which enables operations over various data models. For minimal execution times, it uses a code generation mechanism to mimic the system and storage most appropriate to answer a query fast. We validate our design by building Proteus, a query engine which natively supports queries over CSV, JSON, and relational binary data, and which specializes itself to each query, dataset, and workload via code generation. Proteus outperforms state-of-the-art opensource and commercial systems on both synthetic and real-world workloads without being tied to a single data model or format, all while exposing users to a single query interface.
As the size of data and its heterogeneity increase, traditional database system architecture becomes an obstacle to data analysis. Integrating and ingesting (loading) data into databases is quickly becoming a bottleneck in face of massive data as well as increasingly heterogeneous data formats. Still, state-of-the-art approaches typically rely on copying and transforming data into one (or few) repositories. Queries, on the other hand, are often ad-hoc and supported by pre-cooked operators which are not adaptive enough to optimize access to data. As data formats and queries increasingly vary, there is a need to depart from the current status quo of static query processing primitives and build dynamic, fully adaptive architectures.
We build ViDa, a system which reads data in its raw format and processes queries using adaptive, just-in-time operators. Our key insight is use of virtualization, i.e., abstracting data and manipulating it regardless of its original format, and dynamic generation of operators. ViDa’s queryengine is generated just-in-time; its caches and its query operators adapt to the current query and the workload, while also treating raw datasets as its native storage structures. Finally, ViDa features a language expressive enough to support heterogeneous data models, and to which existing languages can be translated. Users therefore have the power to choose the language best suited for an analysis.

(this article originally appeared in thenextweb.com and was written by Paul McNeil)
The coronavirus pandemic has clearly accelerated our dependency on technology, online activities, and artificial intelligence. AI is particularly important for businesses as it enables personalized services on a massive scale, and customers are increasingly demanding it.
However, not every company has the knowledge or the tools to implement AI, nor do they know what is required from them to become AI-driven. In this post, I will discuss what options these companies have.
It is important to note that while many of the methods described below assist no-coders, they are also suitable for developers, who can enjoy the extra development speed they bring in.
Ever since I was learning to program, the idea of developing a tool that could create applications with plain English commands was floating around. Many years later, OpenAI’s GPT-3 managed to get quite close to this idea as we saw demonstrations of code and HTML markup being written by the text generator.
GPT-3 stands for Generative Pre-trained Transformer 3, which demonstrates the idea of training an AI on colossal amounts of data, then using that built-in knowledge to get stunning results for new tasks with little or no training. GPT-3 was trained using huge amounts of data including, among others, Common Crawl and Wikipedia. But more importantly, it was on supercomputers which enabled it to amass 175 billion parameter values, making it the largest AI model developed to date.
This has enabled the AI to use its current learnings and transform it to apply to other tasks. Transformative AI has many advantages, as it takes much less time to train and gives a head start compared to developing from scratch. It also makes AI much more accessible: companies only need to share their specific data with the model to make it their own. For instance, Anyline’s no-code AI trainer helps companies build their own text reader solutions (such as ID scanners or license plate readers). Customers simply upload their data into the trainer, which automatically tunes the neural networks for them to produce a customized OCR scanner.
Users do not need to learn how the system works or what the source code and architecture of the application look like—all they need to do is to feed the data they want intelligence on, and the AI adjusts accordingly.
Of course, some degree of AI knowledge is still necessary. According to Drew Conway’s Data Science Venn Diagram, effective development and implementation of AI requires two important skills: hacking skills, and math and statistics knowledge. Without these components in place, companies risk developing an AI that works well in lab settings but fails in when faced with real-world problems.
No-code or low-code
Another popular approach has been no-code and low-code platforms, which enable companies to develop their applications through simple drag-and-drop interfaces. No-code and low-code tools are the next battle frontier of the tech giants, as proven by Amazon’s late entry with its Honeycode platform. We are looking at a $13.2 billion market, which is projected to reach $45.5 billion by 2025.
According to Raj Koneru, the CEO and founder of conversational AI platform Kore.ai, no-code has many benefits. “No-code platform can be easily customized for developing an application. The effort that usually took a few weeks or months before can now be completed in a few hours or days,” Koneru says. This results not only in reduced time-to-market, but also reduced cost and dependency on IT and expensive development teams.
Another benefit is that no-code platforms are easily customizable. According to Koneru, no-code platforms enable you to “implement new logic and can have the changes ready in a matter of hours.” More importantly, it gives power to the people who use the platform most. They can now implement what they need on the fly without the need to explain things to another IT developer.
But no-code platforms also have their drawbacks. Many such platforms are cloud-based, and they tend to lock in clients in the long run. This makes changing platforms down the road problematic and time-consuming. Also, no-code applications tend to work well within their defined boundaries, but the struggle as soon as users need extra features that go beyond the built-in capabilities of the system.
Of course, there are ways to overcome these problems. For instance, while Kore.ai offers a drag-and-drop interface for virtual assistant builders, it also grants API connections to developers which gives them much more freedom to develop extra features. The same goes for Radial, an AI platform that helps e-commerce businesses analyze their customers. They offer a plug-and-play solution for regular users and API tools for more advanced clients.
The optimal approach
The importance of AI cannot be underestimated. Without extracting value and information from data, companies will be at a competitive disadvantage. What approach you take depends on your business needs and technical capabilities. Between transformer learning, no-code, and low-code platforms, the optimal approach would be one that would enable you to reach your business goals and offer a moderate interface to develop applications without prohibiting you to move beyond the platform’s offerings.

The Mavic Pro camera shoots 4K video (up to 4096 x 2160) at 30 frames per second and Full HD 1080p at 96 frames per second, so you can create incredible slow motion. Its minimum focusing distance is just 19", making it perfect for everything from the ultimate aerial selfies to landscape shots.
With ActiveTrack, just tell the Mavic who to track and it handles the rest. No GPS bracelets or transmitters are required. The Mavic has been trained to detect and recognize a number of common subjects including people, bike riders, vehicles, and even animals. Once you have marked your subject, you can fly around them to create a huge variety of shots, depending on the mode you are in. As the Mavic is tracking, you can even select exactly where you want the subject in the frame.
Three modes are available:
- Follow behind or in front of your subject, or circle it as it moves
- Fly alongside your subject
- Keep the camera trained on your subject while you fly almost anywhere
When you tap on your phone's screen, software translates your touch into a heading, including whether you want it to climb or descend. When you want to change direction, just tap somewhere else on your screen and the Mavic will smoothly turn to the new destination.
When you are flying over changing terrain, like following bikers riding uphill, the Mavic's Terrain Follow function uses height information gathered by the on-board ultrasonic system, and its downward-facing cameras to keep you flying at the same height above the ground even as the ground moves. Just set the height from the ground you want — from 9 to 33' — and focus on getting the right shot.
Sport Mode was designed for fun, giving the Mavic a top speed of 40 mph, all the while ramping up agility and responsiveness, to give you a taste of drone racing. You can also use it to film something fast, or zip out to catch a shot before the moment passes. Even in Sport Mode, the Mavic will stop immediately if you let go of the controls.
FlightAutonomy is the Mavic's brain and nervous system: a complex network of hardware and software that includes five cameras, GPS/GLONASS, a pair of ultrasonic range finders, redundant sensors, and a group of 24 CPUs to process and fuse all of this information
The Mavic is able to position itself accurately in a range of environments, beyond what is possible using basic "optical flow" technology, which depends on a single downward-facing camera and assumes that the ground below is always flat. Mavic is able to sense its environment in 3-dimensions and react to it, ensuring it hovers steadily, whether it is high up on the side of a cliff where downward sensors have no target, or under a forest canopy where satellite positioning is blocked and the ground is covered in uneven markings and obstacles.
As the Mavic flies, it scans the world around it, creating a 3D map that tells it exactly where it can fly and what it needs to avoid. Because it uses vision processing, it can see up to 98' in front and can accurately measure distance up to 49' in front, making it significantly more accurate than sonar based avoidance technologies. When the Mavic detects an obstacle and sees a way around it, it will simply adjust its route to fly around it. If it can't see a way around, it will slow to a stop gently and hover until you tell it what to do next.
In flight, the Mavic uses its compass to tell it where it is heading and the Inertial Measurement Unit (IMU) to tell it how it is flying. An interruption in the data flow from either of these may cause it to fly less reliably, which is why the Mavic has not one, but two of each. Whenever the system detects an inconsistency in one, it switches to the other, keeping your flight steady and reliable.
DJI Goggle Compatibility
The separately available DJI Goggle are FPV goggles designed to make flying totally immersive. The feature two 1080p LTPS displays with a wide 85° angle of view to give you a bird's eye view of the world around you. Built-in OcuSync connectivity means that it links directly to the Mavic and not through a cable or a Wi-Fi link to the controller. This seamless connection yields a delay of only 120 milliseconds.

1. ANY piece of conducting material will work as an antenna on any frequency.
Even a straightened paper clip will work on 160 Meters. All we have to do is properly match the the transmitter to the the paper clip, and the paper clip will radiate ALL of the power fed to it! The aperture of this antenna will have a radius of 5/32 wavelength (.079 sq. wavelengths cross section area); essentially this is close to the theoretical "Isotropic" source. If this antenna is located in "free space", the radiation will be almost equal in all directions.
2. The ONLY reason for building sophisticated antennas is to allow us to CONTROL THE RADIATION PATTERN.
The radiation pattern is controlled by focusing the radiated energy. The geometry of the antenna and the proximity of near-by objects are the main controlling factors.
The total amount of energy radiated remains constant for a given transmitter output power. When this energy is focused, the energy radiated in one or more directions will be increased, and the energy radiated in other directions will decrease. This is what gives an antenna "gain".
3. An antenna has an aperture similar to that of a camera lens. The aperture of an isotropic source is a circle with a diameter of 5/16 wavelength.
The aperture of a dipole antenna is roughly the shape of a rugby ball (elliptical) when viewed from a point 90 degrees from the line of the conductor.
The cross section area of the aperture of a dipole is 1.64 times that of an isotropic source.
When A1 = aperture of a dipole and A2 = aperture of an Isotropic Source:
4. The Dipole antenna.
Contrary to popular belief, the dipole is so named because it has two electrical poles, not two physical poles; it also has two zeros and could have been called a di-zero antenna. When the length is such that the poles are at ends of the conductor and the zeros are at the center, the antenna will be exactly 1/2 wavelength long.
A dipole antenna is exactly 1/2 wavelength long.
A dipole is most commonly fed at the center, where it presents a pure resistive, balanced, 68 Ohm (R68j0) load to the feed line (this is why the popular misconception of two physical poles).
A dipole can be fed anywhere along its length, however CENTER FED and END FED are the most common, and the easiest.
5. The effects of APERTURE INTERFERENCE.
Anything that enters into the aperture of an antenna will affect the operation of the antenna. The effects are pattern distortion, skewing of balance, change of feed impedance and resonant frequency shift; in other words - everything we want to control.
Sometimes it is desirable to cause intentional aperture interference. Placing other conductors into the aperture will cause severe pattern distortion. This can be beneficial when this distortion takes place in such a manner as to focus the radiated energy into a tight beam. This is the basic operating principle of parasitic beam antennas.
6. Ground mounted vertical antennas.
One common practice is to mount one half of a dipole vertically on a conducting surface (ground plane). This reduces the size of the aperture by 50%, resulting in a 3 dB loss. As we have seen, a dipole has 2.15 dB gain over an isotropic source; if a 1/4 wavelength antenna on a ground plane has 3 dB loss as compared to a dipole, that means that the "1/4 wave" antenna has 0.85 dB loss as compared to an isotropic source. Some antenna manufacturers express the gain of their products as "gain over a 1/4 wave". An antenna advertized as having 3 dB gain over a 1/4 wave is the same as as an antenna having 2.15 dBi gain or 0 dBd gain. It's the same antenna - the bigger numbers are just that - bigger numbers!
A somewhat less common practice is to mount a vertical dipole directly on the ground. This practice is fraught with problems. A portion of the aperture is beneath the ground. This induces large currents into the ground surrounding the antenna. With the high (and uncontrollable) ground resistance, these currents result in substantial voltage drops. The power lost to heating the ground does nothing more than make the worms uncomfortable. These losses can be reduced to acceptable levels by installing an extensive ground system (90 - 1/2 wavelength long radial wires placed on the ground at 4 degree spacing is about minimum). The severe aperture interference also causes the antenna to exhibit a high angle of radiation. It would be easier (and cheaper) to elevate the antenna far enough so that the aperture does not touch the ground.
7. Elevated vertical antennas:
One attempt at elevating a dipole antenna resulted in what is commonly known as the 5/8 wavelength vertical antenna. The theory goes something like this:
Alas, it does not perform as expected. There is considerable mismatch between the antenna and the high impedance, single conductor feed line, resulting in radiation from that line. This would not be all bad except that this radiation is in the wrong direction (30-45 degrees up depending on ground conductivity). This approach also did not eliminate the need for an extensive grounding system. Because this antenna does exhibit some gain (approx. 2.9 dB) over a 1/4 wave whip, it has become a sort of de-facto standard for VHF and UHF mobile operation.
Another approach to the problem is the "J-Pole" antenna. In this design, the antenna is elevated at least 1/4 wavelength above ground, thus eliminating the ground losses and "normalizing" the radiation pattern. The Impedance matching between the low impedance feed line and the high impedance of the end of the dipole is accomplished with an open wire stub matching network. A shorting bar is placed at one end of a 1/4 wavelength of open wire line, the dipole is then connected to the open end, and the feed line is connected at the point where the impedance of the feed line matches the impedance of the stub. If Co-axial cable feed line is to be used, a BalUn MUST be used. Attempts to feed this antenna directly with co-ax have met with disastrous results. The 0 Ohms reference point is at the center of the short, NOT somewhere up the side of the "J".
Yet another workable solution to the problem is to use a co-axial stub matching network. The advantages of this approach are that it can be fed directly with co-axial cable, a large reduction in wind resistance making it suitable for mobile operation and its total independence from ground. The major disadvantage is the extreme difficulty of construction. Unless special (expensive) tooling and fixturing is available, it is almost impossible to assemble the matching network! Although it can be done, this antenna is easier (and much cheaper) to purchase (mass produced) than it is to build just one!
8. The PROPER and COMPLETE match.
The match between an antenna and its feed line is only proper and complete when the following conditions are met:
a. The antenna impedance is matched to the feed line impedance. The only "right way" to do this is to use a matching network between the feed line and the antenna. ANY adjustments made to the antenna in order to achieve impedance matching will change the radiation pattern of the antenna.
b. The antenna balance is matched to the feed line balance. When feeding a balanced antenna, a balanced feed line MUST be used. Conversely, when feeding an unbalanced antenna, an unbalanced feed line MUST be used. When it is necessary to mix balances, a BalUn MUST be used. This can be incorporated into the design of the matching network.
9. 1:1 VSWR does NOT indicate resonance.
The Voltage Standing Wave Ratio (VSWR) is only the ratio between the impedances of the feed line and the load.
If we connect a 50 Ohm resistor at one end of a piece of 50 Ohm co-axial cable, and connect a transmitter and SWR meter at the other end, the VSWR will be 1:1. The resistor is NOT, by any means, resonant.
If we connect a resonant antenna that has a feed impedance of 272 Ohms to the end of that piece of co-ax (ignoring any resonance effects of the co-ax), the VSWR will be 5.44:1.
It is possible to cut a piece of feed line to just the right length, and measure a 1:1 VSWR at the transmitter end of that feed line -- the actual VSWR on this line is (infinity):1.
The only practical way to measure the resonant frequency of an antenna is to use a DIP METER at the antenna.
10. High VSWR does NOT cause feed line radiation.
Most radiation from co-axial cable is caused by terminating this unbalanced feed line with a balanced load. The remainder of the radiation is due to other problems such as: dis-continuities in the outer conductor (braid corrosion is a major factor), improperly installed connectors and signal pickup caused by routing the feed line too close to, and parallel to the antenna.
Contrary to popular belief, properly terminated and installed open wire line does not radiate. Even with infinite SWR, the fields surrounding each wire cancel each other at a distance roughly equal to the wire spacing distance away from the line. Terminating the line in an unbalanced load, or causing anything to come within the "field space" will cause unbalance in the line, thus allowing the line to radiate.
11. Antenna Gain Information.
There are four ways of expressing antenna gain. These are:
|dBi||Gain over an isotropic source (a theoretical antenna having no dimensions: a geometric point).|
|dBd||Gain over a dipole (0 dBd = 2.15 dBi).|
|dBq||Gain over a quarter wavelength whip (bigger numbers than dBi).|
|dBadv||LARGE RANDOM numbers generated by the advertizing and marketing departments at some antenna companies. These departments are sometimes known as the "S and M" (Smoke and Mirrors) groups.|
Sad to say, but the advertized gain claims of most large antenna companies are out and out fraudulent. Because most users of antennas can't separate the real numbers from the phony, they wind up paying big money for junk and the honest antenna companies suffer. With lower sales, the honest companies have smaller R&D budgets. New and better products don't get produced. Everyone loses.
This antenna gain chart shows the maximum theoretical (minus a small allowance for system losses) gain achievable from arrays of closely spaced co-linear dipole elements. Dimensions shown are for elements almost touching; the actual heights may be slightly more due to phasing networks used between the dipole elements.

Chairwoman Johnson, Ranking Member Lucas, and Members of the Committee, thank you for holding this hearing, and thank you for the invitation to testify today.
I am Jordan Gerth, an atmospheric scientist who holds an honorary fellowship at the University of Wisconsin-Madison Space Science and Engineering Center (SSEC). My professional service includes chairing the American Meteorological Society Committee on Radio Frequency Allocations. Established in 1965, SSEC is an internationally respected organization for the research and development of remote sensing and environmental applications. Madison, Wisconsin, is the birthplace of satellite meteorology, in large part due to the work of the late Dr. Verner Suomi, a professor that developed the spin-scan cloud camera to provide the first animations of weather patterns in the 1960s.
In holding this hearing today, you implicitly recognize the importance of radio frequencies for Earth and space science applications. There are a growing number of important issues related to spectrum sharing with 5G wireless communications, both for the atmospheric and oceanic sciences and radio astronomy, and also related to the transmission and collection of weather information. My testimony today will focus particularly on the criticality of protecting the clarity of Earth-emitted radio frequencies to maintain the quality and public confidence in weather warnings and forecasts and the need for transparent processes to facilitate that objective.
Importance of sustaining passive microwave sensing for weather forecast accuracy
Basis for microwave sensing. While the accuracy of weather forecasts is popular fodder as a conversation starter among Americans, the reality is that weather forecasts have never been more accurate in history. Weather forecasts for the contiguous United States are particularly accurate. The seven-day forecast today is as accurate as the five-day forecast was 20 years ago. The most important aspect of making the right forecast is taking the right observations and using them effectively. That is where the nexus between radio frequencies and weather forecast lies.
While visible or infrared satellite imagery as shown on the evening television news weather report partially contributes to the quality of weather forecasts, the most valuable frequencies are microwaves, particularly those between 20 and 200 GHz. It likely comes as a surprise to many that the Earth’s atmosphere emits microwaves, but they are naturally occurring and not harmful to us.
Molecules such as oxygen and water vapor emit microwaves at unique frequencies, and those emissions help meteorologists identify and characterize weather systems and develop a vertical profile of temperature and humidity without releasing a weather balloon. Microwaves are additionally useful for weather analysis because they typically traverse through clouds without absorption and thus enabling meteorologists to examine the internal structure of storms in determining whether strengthening or weakening is likely.
Current instrument for microwave sensing. Given the benefits of microwaves, satellites have been designed to sense them for over 40 years. The most recent NOAA instrument to sense atmospheric microwaves is the Advanced Technology Microwave Sounder, or ATMS. The ATMS is considered a passive sensor because it is “listening” to the atmosphere. This is unlike a radar which itself emits a pulse and then “listens” for the return.
As soon as next year, NOAA will launch its third satellite, the second in the Joint Polar Satellite System (JPSS), with an ATMS instrument. As each JPSS satellite orbits the poles every 100 minutes from 500 miles above the surface of Earth, ATMS collects 22 distinct observations of the atmosphere every 10 to 50 miles within a 1,370-mile swath. A single JPSS satellite observes every location on Earth at least twice daily. Of those 22 observations, ATMS is designed to sense at 23.8 GHz, among other frequencies, to collect information about water vapor. 23.8 GHz is sensitive to concentrations of water vapor near the ground and when used in combination with other frequencies can contribute to a vertical profile, or distribution, of humidity at various heights above the ground. This is useful information for precipitation forecasts.
Numerical weather prediction. The importance of JPSS and other weather satellites that NOAA, NASA, and other nations operate in providing observations for weather forecasts created with supercomputers cannot be understated. Approximately 99% of weather observations that supercomputers receive originate from satellites, and after quality control, approximately 90% of observations assimilated, or integrated, using complex algorithms into computer weather models are from satellites.
The collection of complex algorithms is known as a numerical weather prediction model because the model converts observations into a numerical representation of the atmosphere and then advances it forward in time. At its core, weather forecasting is an initial-value math problem. Thus, if observations do not provide a complete assessment of the atmosphere, then weather forecasts will be less reliable and less accurate over time.
Improvements in numerical weather prediction performance over the past 20 years can be attributed to satellite observations, especially microwave sensing of water vapor, such as at 23.8 GHz and other frequencies. Today, approximately 15 to 30% of the assimilated observations are from passive microwave sensing. A 2020 study from Europe found that microwave sensors led to forecasts that were “very significantly improved at short lead times, 12 to 24 hours,” and also beneficial but, to a lesser extent, out to four days in the Northern Hemisphere. These observations are approximately twice as valuable in reducing model errors out to six days as the three next most valuable observation types individually, including hyperspectral infrared radiances, radiosondes, and radio occultations.
Microwave sensing harm from 5G. Terrestrial radio systems that emit 5G signals too closely to defined bands for weather sensing are a formidable threat to weather forecast and warning services because they are much louder than the atmosphere that satellites are trying to observe. Harmful interference is likely because if the 5G signal is so loud that it is obvious, it will easily mask the atmospheric emission such that it is irrecoverable. Even if the 5G signal does not overpower the atmospheric emission completely, it will still be extremely difficult, if not impossible, to separate the contribution of the atmosphere from the 5G signal with current assets. Because the satellite sensors are only “listening”, there are no good options to mitigate this interference.
To state it clearly: If there is no observation of a portion of the atmosphere because of 5G signal interference there, it cannot be the basis for a weather analysis and global and local forecasts may suffer alike, leading to a loss of lead time for storms. Using a 5G-inflated observation could lead to a worse forecast unless numerical weather models are configured to use microwave observations with a decreased confidence in their quality, a mitigation that would have far-reaching complications for weather forecasts beyond where there is interference.
Policy options for protecting spectrum for science applications through improved processes
A growing challenge. Spectrum allocation issues have been a growing concern for the weather enterprise beyond the Federal Government. Previously, NOAA and NASA worked behind the scenes to resolve issues with limited if any contributions from academic and industry partners. However, as the appetite for more wireless spectrum has increased, more scrutiny of each proposal is necessary. At a minimum, NOAA and NASA should share their studies publicly and expediently, something that was missing for 24 GHz in 2019.
When the FCC issues a new notice of proposed rulemaking for 5G services, there are two separate questions that should be addressed:
1. Will this rulemaking proposal lead to interference with satellite sensors?
2. If it does, to what degree will that interference lead to a degradation in the accuracy of weather forecasts?
Collectively, the answers to these two questions can inform the best course of action for spectrum sharing, and tough decisions may need to be made. However, the answers to these questions are not straightforward, take substantial time to address, and the best way to answer them is with better coordination and cooperation between the FCC, NTIA, NOAA, and NASA and in a manner that is transparent. In particular, the second question is most challenging to answer because to depends substantially on the deployment strategy of the new 5G network.
Actively valuing spectrum for weather prediction. As part of the Weather Research and Forecasting Innovation Act of 2017, NOAA is required to conduct an Observing System Simulation Experiment (OSSE) before buying or leasing a new weather satellite or new weather satellite data set that costs at least $500 million. This directive could be expanded, potentially using spectrum auction revenues. NOAA, NASA, and other agencies that operate satellites for environmental sensing should regularly audit the use of spectrum and recent, peer-reviewed studies from federal and federally supported scientists, such as those at NOAA Cooperative Institutes, should reflect the application and value of each radio frequency sensed, in terms of contribution to numerical weather prediction skill through a data denial experiment or otherwise.
This valuation should be conducted routinely because the speed of peer review is much slower than FCC proceedings. FCC proceedings have timelines of 60 to 90 days for comment while funding research for peer review related to a new proceeding is likely to take 18 to 24 months at a minimum. A new satellite currently takes 5 to 10 years to build and launch, and those program costs are in the billions per satellite. The estimated total cost of the JPSS program from 1995 through 2038 is $18.8 billion, so a loss of sensing capability that diminishes its intended mission has a real tangible cost for taxpayers even without considering the economic loss from the reduction in weather predictability.
Integrating science into transparent decision-making. In light of the GAO findings and recommendations, I am left wondering what recourse NOAA, NASA, or another government agency has if the FCC and/or the Department of State does not allay their raised concerns about shared spectrum rulemaking proposals. Chairwoman Johnson and Ranking Member Lucas were rightfully concerned about the potential of weather forecast degradation in calling for the GAO to investigate the governmental processes that have led us to this point. Yet, as a scientist, it is discomforting that the FCC can conduct rulemaking without studies that could have an impact on another agency to accomplish its Congressionally directed mission.
This Committee should consider whether oversight or involvement from the Office of Science and Technology Policy (OSTP), federal advisory committees, or other mechanisms that, at a minimum, conduct and make publicly available all relevant scientific studies prior to a rulemaking decision, may facilitate a process with more integrity for all stakeholders. While I understand that the FCC does not fall under this Committee’s jurisdiction, legislative remedies that require proactive and closer cooperation on the sharing of Earth exploration-satellite service-allocated spectrum between the FCC, NTIA, NOAA, and/or NASA specifically may also be necessary. Policy priorities for expanding 5G with sustaining the quality of weather forecasts must be balanced.
Working together. Despite the importance of maintaining the accuracy of weather forecasts, the weather enterprise is not a competitor of the telecommunications industry, and we should not characterize this issue as one of us versus them. The telecommunications industry is an essential partner is delivering urgent weather messages to cell phones and establishing communications immediately after a disaster to assist in the response. I truly believe that with a better understanding of how satellite sensors collect weather information and how those observations improve weather forecasts that industry partners can work with us to deploy equipment outside of pre-existing bands for Earth sensing.
The future of spectrum allocations and weather satellite observations
In our national conversations about 5G, we are forward-looking into how technology will evolve the economy, expand opportunities, connect Americans, and improve society. We should apply the same mindset to weather prediction and satellite observations. The accuracy of weather forecasts improves by one day every decade, and this is a trend that we can continue with sustained investments into NOAA and NASA satellite programs and exploring options to partner with the expanding space enterprise.
On the horizon, the capability of small satellites and cube ‘sats’ is increasingly promising to enhance the temporal frequency of passive microwave sensing, though they are not yet a proven replacement for flagship missions like JPSS. In the coming decades, there is the prospect of microwave sensing from the geostationary orbit, approximately 22,500 miles above the surface of Earth, to provide continuous monitoring of the internal dynamics of hurricanes over our adjacent oceans for the first time. Though not imminent solutions, both innovations would benefit from protected allocations for Earth exploration-satellite service (EESS) at microwave frequencies and increase weather predictability.
Finally, the United States has been a leader in weather satellite observations that now extends back 60 years, a history that began in Wisconsin. We should continue our national leadership in demonstrating stewardship of our spectrum resources for science applications and particularly weather sensing. Pushing the frontiers of weather forecasting out to and beyond 10 days will depend not only on our domestic spectrum policy but also our current and future ability to conduct passive microwave sensing over the remainder of North America, our adjacent oceans, and other continents, particularly Asia and Oceania. The United States should advocate at future World Radiocommunication Conferences (WRC) accordingly.
While the contentious circumstances surrounding 24 GHz were far from desirable, and 23.8 GHz sensing contributes useful water vapor information for weather forecasting that we may partially lose, the longest heritage of microwave sensing is between 50 and 60 GHz, where there are 13 ATMS bands. We should be especially careful of sharing arrangements in and around 50 to 60 GHz or the consequences for weather prediction may be more dire.
Thank you for holding this hearing and allowing me to explain the science that underlies the importance of passive microwave sensing for weather forecasting and how processes that require scientific input can benefit from increased transparency. Despite its complexity, establishing a process that enhances decision-making for certain spectrum allocations with science applications will benefit all parties and the American public. I appreciate your support in increasing confidence in our nation’s weather warnings and forecasts and maximizing the value of the United States investment in weather sensing from space.

fit-PC Slim is a Windows/Linux computer squeezed into a 330cc enclosure - 40% smaller than the 560cc fit-PC 1.0
Miniaturization does not mean compromising on features - fit-PC Slim adds memory, WiFi, a third USB port, a power button, LED's and a redesigned hard disk mounting for easy upgrade. The stylish design of fit-PC Slim is an advantage where the industrial look of fit-PC 1.0 would appear out-of-place.
Double the memory
The most requested enhancement - higher memory capacity - is now a reality! fit-PC Slim has 512MB RAM, while remaining faithful to the soldered, on-board approach that ensures low power consumption and high reliability.
Upgradeable hard disk
Another much requested feature - enabling hard disk upgrade - in fit-PC Slim is a matter of opening two screws, sliding out the existing hard disk and sliding in a new one. Unlike the fit-PC 1.0's deeply buried hard disk, fit-PC Slim can be easily fitted with a high capacity hard disk or SSD. You can also order fit-PC Slim without a hard disk and install your own.
fit-PC Slim has built in 802.11b/g WiFi enabling use anywhere, at home or in the office, without the hassle of cables.
Additionally, the WiFi in fit-PC Slim supports access point mode so the fit-PC can be used as an intelligent wireless router.
fit-PC Slim has 3 USB ports, two of them in front, through which a keyboard and mouse, thumb drive, camera external hard disk or CD-ROM can be easily connected without the need of a hub.
Power button and Indicator LEDs
fit-PC Slim has a functional PC front-panel with a tactile power button and LED's indicating power and hard disk activity.
12V power supply
The power supply in fit-PC Slim is 12V and tolerates between 9V and 15V. This allows for easy connection to a car battery or solar panels and increases reliability by having extra regulation within fit-PC Slim. fit-PC Slim uses a standard 3.5 power plug to simplify connection to an alternative power source. The new power adapter is smaller and has a standard "kettle lead" IEC-C13 AC inlet.
fit-PC Slim Linux is shipped with preloaded Ubuntu 8.10 and Gentoo 2008.0 in dual boot mode.
fit-PC Slim XP is priced at $335 with Windows XP Home SP3 pre-installed, versus $395 for fit-PC 1.0 with Windows XP.http://www.fit-pc.com/fit-pc1/whats-new.html

CaptureGRID 4 is a digital photography work flow application for tethered shooting, remote capture and advanced camera control.
Multi-Camera Control allows you to fully control and synchronise all your cameras simultaneously, including camera settings, triggering, live view, photo download and filename management.
Networked Operation across multiple computers allows you to scale up the number of cameras and orchestrate large multi-camera capture rigs.
CaptureGRID supports all recent DSLR cameras from Canon and Nikon, as well as some cameras from the Sony Alpha range. We regularly update the app, so support for new cameras is added as they come on to the market.
The software uses wired USB connection for direct communication with the cameras, using our custom built PTP engine. This delivers reliable camera control and fast photo downloads.
CaptureGRID runs on Windows, macOS, and Linux.
The software also supports a wide range of hardware, and can adapt to make optimal use of the hardware resources available. This means it can even run on single board computers such as the Raspberry Pi, but also scale up and make use of high-performance multi-core workstation PCs and Macs.
CaptureGRID allows you to connect and control a large number of cameras, by splitting the USB connections across multiple computers. This means the number of cameras is not limited by the USB hardware capabilities of a single computer, but instead can be scaled up by adding more computers.
When all computers are connected and synchronised, the user can operate the app from just one of the computers, to get a unified view of all cameras and photos, and be able to take actions on all cameras at the same time.
CaptureGRID gives you precise control over what happens to your photos. After capture, photos can be either saved to memory card, automatically downloaded to the computer, or both.
If your cameras are split across multiple computers, the software has options to transfer photos across the network and gather them in a single location, ready for the next step of your workflow.
The app will manage the filenames given to each photo, taking into account which camera it came from, and can automatically organise them into subfolders.
This mechanism can be easily configured to match the filenaming scheme you need for your processing workflow.
The app can trigger multiple cameras itself, but for improved accuracy of trigger timing it can also be used together with an external trigger system.
For example, dedicated TriggerBox and lighting hardware from ESPER can be combined with CaptureGRID for a complete 3D capture system. In this scenario the Esper components take care of precise triggering and lighting, and CaptureGRID handles sychronisation of camera settings, automatic photo download, and filename management.
CaptureGRID can be integrated with an external system by using the External API feature. This provides two key channels of communication that you can hook into, to listen to a stream of event information coming from the app, and to send requests to the app to control the cameras.
The app itself has scripting support for automating the control of the cameras. There are some built-in scripts provided with app, for tasks such as bracketting, HDR, and timelapse, and you can write your own using Python.
For instructions on how to install and operate the software, and more detailed information on the various features, please refer to the Documentation.
If you have general or technical questions, want to report a bug or request a new features, or just share information with other users, please visit our Forums.

The history of the doctoral and master’s programs in physics at the University of Tsukuba dates back to its predecessor, the Tokyo University of Education, where Dr. Shinichiro Tomonaga developed renormalization theory in quantum electrodynamics and won the Nobel Prize in Physics in 1965. Since then we have continued to produce significant research results, which have been recognized by the prizes and awards such as the Nishina Memorial Prize, the Japan IBM Science Prize, the Japan Society for the Promotion of Science (JSPS) Prize, the Japan Academy Prize. More recent accomplishments include the discoveries of the top quark and the Higgs particle. We conduct research in advanced areas of physics, and will continue to produce world-class results.
The degree programs in physics offer education and research in the following fields.
- Particle physics
- Theoretical particle physics, Experimental particle physics
- Theoretical Astrophysics, Observational Astrophysics
- Nuclear physics
- Theoretical Nuclear physics, Experimental Nuclear physics (Low energy nuclear experiments, High energy nuclear experiments, Atomic cluster experiments)
- Condensed matter physics
- Theoretical condensed matter physics (Non-equilibrium statistical mechanics, Quantum theory of condensed matter, Nano-quantum materials science physics, Soft matter theory, Semiconductor nano-materials science physics, Nano-structure materials science physics), Computational biophysics, Experimental condensed-matter physics (Magnetic materials physics, Semiconductor physics, Strongly-correlated materials physics, Surface physics, Low temperature physics)
- Plasma experiment, plasma simulation, Analysis of plasmas in large-scale fusion devices
The curriculum of the degree programs in physics is systematically organized by taking advantage of its two-term structure. In the master’s program, students learn the broad basics of physics in fundamental subjects, acquire advanced knowledge in each field in specialized subjects, and then carry out creative research under close supervision by advisors. The program is aimed at fostering researchers and highly-skilled professionals who possess a deep understanding of physics, have creativity in research in their specialized fields, and have flexibility to apply their skills to other sciences and technologies. In addition, the program offers an English Course for English-speaking students, enabling them to gain a master’s degree solely by attending classes given in English.
The doctoral program is designed to help students acquire a broad perspective through research, and become independent researchers by developing basic skills, application skills, and the determination and endurance. In particular, a doctoral dissertation needs to be written in English, and in many cases be reviewed by committee members consisting of leading extramural researchers in the field.
In the fields of particle physics, nuclear physics, and astrophysics, we offer a special educational system: the Unified Educational Program for the History of the Universe. Graduate students enrolled in this program can conduct their research in a relatively long term at overseas research hubs, and thus obtain international research expertise. Also, the Educational Program for the High Energy Accelerator Science is offered in cooperation with the High Energy Accelerator Research Organization (KEK) on education and research. In addition, we offer the Dual-Degree Program, which enables the students to obtain both a doctoral degree and a master’s degree in different fields of academics, for example, a doctoral degree in theoretical nuclear physics and a master’s degree in computer science. For researchers having achieved adequate research results in industry or other institutions, we offer the Early-Ending Program, which enables completion of a doctoral program in one year at the shortest.

I was starting to panic, as I am running the Liverpool half-marathon tomorrow and the chest strap monitor that came with my Garmin Forerunner 305 suddenly stopped working yesterday. Previously there had never been any problem with the Ant+ device - the HRM1G - so I was a bit concerned.
After replacing the battery twice, I was no further forward. I even tried resetting the Forerunner unit itself.
A couple of Google searches later I came across this thread suggesting reversing the battery. I tried it, and the HRM1G registered straight away with my Forerunner unit. How very relieved I am.
Although the Garmin forum thread suggests that the polarity has been reversed, in effect the upturned battery is just short circuiting the two contacts due to the shape of the battery.
A useful hint to know.

Researchers are developing novel neuroelectric devices for communicating with neurons in the brain. These devices can stimulate neurons and detect their signals with transducers . Nexuses between a human brain and a robot/machine are of plausible interest to avant-garde neuroscientists. Current applied research in this field includes:
• Bionics - the replacement of damaged or amputated body parts with prosthetic limbs connected to and controlled by the human neural network (see Figure 1).
• Bioimplantronics - the technology of implanting electronic devices in biological organs.
• Neuroelectronics - implanting electrodes in different parts of the brain for electrotherapy, electroencephalography, and neuroprosthetics.
The field of bionics has marked a course of rapid advancement aimed at aiding amputees and the handicapped with artificial limbs just as real in their functions as the original (see Figure 2). Amputees will soon be able to control robotic limbs by just thinking through the motions .
Circuitry implanted in the body is not science fiction, but an everyday fact of life. The US Food and Drug Administration has approved the implantation of radio-frequency identification (RFID) tags in human subjects. The tags have been used as "e-passports" in the past and more recently are being employed as "e-keys," patient identification records, and identity tracking chips . These biological chip implants might in the future integrate directly with the central nervous system so that a soldier with the implant could transmit visual, auditory, or tactile information about the enemy or imminent danger to a main station with just a thought.Could the quest for immortality be satisfied simply by uploading our memory and mind to a terabyte-size data storage mechanism? Does our consciousness permeate brain machine interfaces that allow amputees or locked-in patients to regain limb functionality? Or is our consciousness just a byproduct of neural firings in the bioelectric circuitry of the brain? Before envisioning the challenges and prospects of neuroelectronics, let us first revisit its past, which defined the modern scientific theories of the brain.

Artificial Intelligence and machine learning have made it possible for organizations around the world to improve processes and optimize efficiency. However, it has growing limitations with its ability to differentiate correlation and causation.
That means we think we’re being data-driven, but we’re actually jumping to the wrong conclusions.
The impact of this can be comical like the graph below. It shows that the trend line of revenue generated by arcades maps closely to computer science doctorates awarded in the US. So if we want more computer scientists, we just need to get more people to spend money at arcades. Right?
To make human-level data-driven decisions, we need an innovative approach to analytics that separates correlation from causation. Luckily, it’s not only already here and picking up speed…it’s trending.
All Aboard the Causal AI Hype Train, It’s a Bright Future Ahead
Gartner released their 2022 Gartner Hype Cycle of emerging technology and Causal Artificial Intelligence (Causal AI) was featured as a key innovation that will transform the world within the next ten years.
Dealtale is in good company driving this train alongside companies like McKinsey and Microsoft. Across industries, we’re breaking open the black box that predictive analytics lives in to make data insights actually actionable.
As Gartner defines it:
“Causal artificial intelligence (AI) identifies and utilizes cause-and-effect relationships to go beyond correlation-based predictive models and toward AI systems that can prescribe actions more effectively and act more autonomously.”
While a machine learning algorithm can provide insights with predicted outcomes, it can’t tell you how different decisions will change the results.
A common example Forbes outlined in a recent article on Causal AI is geared towards retail marketers who need to run an offer, but can only select one cohort to run the promotion for. A predictive model might tell them that the highest likelihood to buy would be loyal shoppers. So the marketer might send the promotion to them, see the big return on sales, and think “Data-driven success!”
But wait. Wouldn’t those loyal customers buy already without incentive?
To truly measure the increased gross margins, you would want to do an A/B test or leverage a causal algorithm.
Causal AI Turns Predictive Insights Into Prescriptive Actions
Causal AI algorithms move beyond predicting who would be the most likely to buy, they guide on the most effective way to make it happen. When marketers are looking at a campaign and considering how they should promote through ads, email, or mail, they want more than just a spreadsheet—they want prescriptive suggestions they can trust.
*An excerpt from KDD poster “ML Prescriptive Canvas for Optimizing Business Outcomes” by Gerben Oostra.
According to Forbes, it’s the trust that Causal AI can generate that is driving the industry toward it at full speed; decisions are more transparent, results can be reproduced, and bias is eliminated. It brings the human ability to understand the larger context of casual and effect into the equation and delivers better business results.
Join Gartner Aboard the Casual AI Hype Train Today
Introducing Causal AI into your business will help make predictions more accurate so you can make faster, smarter decisions with predictable results. The good news is that you don’t have to wait.
Get ahead of the curve. Dealtale’s Causal AI is ready and waiting for you. It is out-of-the-box, no code, and is easy to implement. Check out our free two-week trial.

Hitachi Energy hands over North Sea Link, the first interconnector between Norway and the UK
Hitachi Energy has announced it has handed over the North Sea Link power interconnector to Statnett, the national power grid operator in Norway, and National Grid, which owns and manages gas and electricity infrastructure in the UK and northeastern United States.
The link, which is the world’s longest subsea power interconnector, is enabled by HVDC Light®, Hitachi Energy’s high-voltage direct current (HVDC) technology, interconnects Norway’s and the UK’s power grids, which are separated by the North Sea.
North Sea Link has the capacity to transmit 1,400 megawatts (MW) of renewable power through a 720-kilometer HVDC underwater cable, which is enough electricity to supply 1.4 million UK homes.*1 It allows Norway to import wind power from the UK and the UK to import hydropower from Norway. This efficient power exchange will help increase grid resilience in both countries, reduce fossil-fuel power generation in the UK and avoid 23 million tons of carbon emissions by 2030.*1
“North Sea Link is a cornerstone of Europe’s carbon-neutral energy future, interconnecting national power grids and enabling the flow of electricity across borders and seas,” said Niklas Persson, Managing Director of Hitachi Energy’s Grid Integration business. “The link increases power supply reliability and security in both countries, accelerates progress toward their sustainability targets, and facilitates power trading and economic growth.”
“This is an exciting day for National Grid and an important step as we look to diversify and decarbonize the UK’s electricity supply. North Sea Link is a truly remarkable feat of engineering,” said Nicola Medalova, Managing Director for National Grid Interconnectors. “North Sea Link is a great example of two countries working together to maximize their renewable energy resources for mutual benefit.”
Hitachi Energy designed, engineered, supplied and commissioned the enabling technology for the interconnector – two HVDC Light® converter stations, one at Blyth in northeast England and the other at Kvilldal, Norway. The stations convert the alternating current power from the grid into direct current for efficient transmission in the subsea cable, then reconvert it back to alternating current for use in the receiving grid.

Industrial Control Systems (ICS), the utility grid, and the Industrial Internet of Things (IIoT) constitute a wide range of devices and services, including many that are in the class of critical infrastructure. The growing number of operational technology endpoints connected to the Internet increases the cyber-attack surface exponentially, introducing new vulnerabilities and attack vectors.
Unique and Scalable Solution
Invisinet Transport Access Control (TAC) is well suited to protect distributed operational technology devices and supporting cloud services. TAC operates end-to-end across network and cloud boundaries, regardless of network topology. Invisinet segments and isolates SCADA and IIoT devices blocking scanning, discovery, and access from all unidentified and unauthorized devices and systems. It closes attack vectors by allowing only authorized and authenticated inbound and outbound network sessions. Invisinet TAC operates prior to a session or connection being made, effectively rendering critical infrastructure networks and IIoT devices invisible to attackers. Low host compute requirements support integration with many different types of operational devices. Invisinet can be deployed on a device or in a network segment architecture to communicate identity on behalf of individual IoT sensors or SCADA devices. This supports both new and legacy environments, providing scalability supporting millions of devices.
Delivering strategic value to operational environments:
- Stops cyber-attacks and unauthorized visibility: Invisinet provides a new and fundamental solution to protect against advanced persistent threats and attacks by dropping unnecessary and unwanted traffic
- Regulatory compliance: Utilities and critical infrastructure operators are faced with increasing regulatory compliance requirements. NERC Critical Infrastructure Protection (NERC CIP) is a set of requirements designed to secure the assets required for operating North America’s bulk electric system. Invisinet protects those critical assets by enabling identity based access to those systems and supporting networks
- Privacy: The connection of utility systems and IoT devices significantly increases the level of information shared across various organizations. Access to sensitive information must be tightly controlled. Invisinet proactively discards unauthorized traffic from entering or leaving a network – only authenticated connections are allowed to be established

In the past few decades, diagnostic technology has come a long way to helping healthcare teams and their patients detect health conditions earlier, better understand existing medical issues, and improve treatment planning and prognoses.
At Premier Imaging, we use advanced diagnostic technologies to provide our referring physicians and their patients accurate, decisive, and consistent interpretations complemented with high-resolution images on a prompt and timely basis.
With these technologies, we can look inside of your body to diagnose and monitor many different types of diseases and medical conditions, from internal injuries to tumours. The type of diagnostic test we run depends on your doctor's orders, which are based on your symptoms and the part of your body that needs to be examined.
Many imaging tests are painless, non-invasive and easy, while others are more complex and take a few minutes longer.
By leveraging state-of-the-art tools to take ultrasounds, mammography, X-Rays, and bone mineral density tests, we can share information efficiently with healthcare teams and offer precise, potentially life-saving diagnoses.
This non-invasive diagnostic imaging technique uses sound waves to produce images of the inside of the body. At our Ottawa clinic, we use this technology for general, musculoskeletal, obstetrical, vascular, and 3D ultrasounds.
A specially designed X-Ray machine uses low-energy radiation to capture multiple images using a high-resolution camera. During a mammogram, the breasts are positioned between two plastic imaging plates.
With X-Ray technology, we use electromagnetic energy to see through tissue to examine fractured bones and soft tissue. X-Rays (radiographs) can help us diagnose infections, heart problems, blocked blood vessels, arthritis, and other conditions.
During a bone mineral density test, we use an enhanced form of X-Ray technology to measure bone loss. DXA (dual-energy absorptiometry) machines feature special software to convert data and display measurements of bone density on a computer monitor.
We'll collaborate with your healthcare team to create a streamlined imaging and diagnostics process. Find out how we can help.

Circuit breakers are automatically operated electrical switches with on and off buttons. They are intended to safeguard an electrical circuit against damage caused by excessive electrical currents.
You must understand electricity to understand how a circuit breaker works. Electricity has three main qualities: resistance, voltage, and current.
Voltage works like pressure on the conductor to transfer the electric charge. The rate of flow is described as current. And resistance occurs when an electric current interacts with a conductor — various types of conductors give varying degrees of resistance, which is why certain materials conduct electricity better than others.
The wiring in your home should be made up of three different types of wires: a hot wire that generates heat, a neutral wire, and a ground wire. Normally, the hot and neutral wires never come into contact, and the current flows through an appliance that adds a high degree of resistance to the current in order to maintain the voltage at safe levels.
If the hot and neutral wires come into contact for some reason, the current will immediately experience significantly reduced resistance, causing voltage and current levels to rise to levels dangerously close to those of fire. When the current and voltage levels on a circuit get too high, the circuit breaker trips, cutting off power to the circuit.
Three Reasons Why Circuit Breaker Keep Tripping
1. Circuit Overloads
Circuit overload is one of the most common causes of circuit breakers tripping on a regular basis. This happens when you expect a specific circuit to have more power than it actually has. This will cause the circuit to overheat, putting all of the electrical equipment connected to the circuit at risk.
For example, if your television is connected to a circuit that requires 15 amps but is now using 20 amps, the television system’s circuit will be fried and destroyed. To avoid this from occurring, the circuit breaker trips, possibly preventing a major fire.
You can solve this problem by redistributing the electrical equipment and taking them off the same circuits. To – the electrical load on the circuit breaker, you can also switch off certain devices.
2. Short Circuits
A short circuit, which is more dangerous than an overloaded circuit, is another common cause for circuit breakers to trip. A short circuit occurs when a “hot” wire in one of your electrical outlets comes into contact with a “neutral wire.” When this occurs, a huge amount of current flows through the circuit, producing more heat than the circuit can handle. As this occurs, the breaker trips, shutting down the circuit and preventing potentially harmful incidents such as a fire.
Short circuits may occur for a variety of reasons, including defective wiring or a loose link. A short circuit can be identified by a burning odor that is normally left around the breaker. You may also spot a brown or black discoloration around it.
3. Ground Fault Surges
Surges caused by ground faults are similar to short circuits. They happen when a hot wire comes into contact with a bare copper ground wire or the side of a metal outlet box that is attached to the ground wire. This will allow more energy to flow through it, which the circuit will be unable to manage. The circuit breaker trips to protect the circuit and equipment from overheating or possible fires.
If ground fault surges occur, you may notice discoloration around your outlet. If you avoid or neglect either of these issues, you are jeopardizing the protection of your home and loved ones. If your circuit breakers are regularly tripping, it is time to call in professionals to investigate the issue. Do not attempt to solve this problem on your own.
How to Reset a Tripped Circuit Breaker
1. Locate the Circuit Breaker Box
Circuit breakers are typically found in a gray metal main service box in a utility area such as a basement, laundry room, garage, or utility closet. The main breaker box may be housed in a wall cabinet if it is located in a finished space. If your home does not have a main circuit breaker box, your electrical service is most likely older, and the circuits could be operated and secured by fuses. Fuse boxes work in the same way as breakers, but they need a different procedure to repair the circuit if a fuse “blows.”
If you’ve found the main circuit breaker box, open the metal door and aim for a bank of rows of switches. The circuit breakers in the box might be of various forms, but they all work in the same way. And they are all reset in the same way.
2. Identify the Tripped Breaker
Look for the breaker whose switch lever has been moved away from the ON position. It would most likely be the only one with a trigger that does not point in the same direction as the other breakers. Most circuit breakers have an orange or red marker window that indicates when it has tripped. If there is no indicator, look for a switch that has been fully turned off.
3. Turn Off Lights and Appliances on the Circuit
Most experts suggest that no electrical load be applied to the circuit at the time the tripped circuit is reset. This is not needed, but it is a highly recommended safety precaution. Switch off all light fixtures and appliances that are connected to the circuit.
4. Flip the Circuit Breaker Switch
To reconnect your circuit and restore control, turn the switch to the ON position. For certain circuit breaker models, this reset action can entail completely extending the breaker lever to the OFF position and then returning it to the ON position. As the breaker clicks to the ON position, you can feel resistance in the trigger, accompanied by a distinct clicking sound or sensation.
5. Test the Circuit
Switch on the circuit’s lights and appliances. If the circuit breaker trips again, it’s time to call an electrician because it means a more severe issue with the circuit.
Avoiding Tripped Breakers
A circuit breaker that trips repeatedly, or that trips immediately after being reset, indicates that something more serious is present. Circuit breakers usually trip when a circuit draws too much current for the amperage rating of the circuit breaker and the wires it feeds.
The best way to avoid this form of tripping is to reduce the electrical load on the circuit by switching appliances to outlets fed by different circuits. This is most common with appliances that have motors or heating elements, as these appliances put a relatively high electrical load on circuits.
If this is not feasible, you will need to hire an electrician to perform an electrical upgrade, which will allow you to add more circuits to your system. Large appliances, such as dishwashers, microwave ovens, and garbage disposals, should be on their own “dedicated” circuits, but in older households, two or more appliances are often fed by a single circuit.
Such circuits are more susceptible to overloading and tripped breakers, so you may want to update the system to avoid this.

Transcranial magnetic stimulation (TMS) is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression. TMS is typically used when other depression treatments haven’t been effective.This treatment for depression involves delivering repetitive magnetic pulses, so it’s called repetitive TMS or rTMS.During an rTMS session, an electromagnetic coil is placed against your scalp near your forehead. The electromagnet painlessly delivers a magnetic pulse that stimulates nerve cells in the region of your brain involved in mood control and depression. It’s thought to activate regions of the brain that have decreased activity in depression.
Please make an appointment with our specialists to discuss this treatment/review.

At it’s most basic, Gemini is a way of transmitting up to 6 pieces of discrete information to the performer without the participant(s) knowing that they have done so. These pieces of information can be revealed on their own as an outstanding revelation, or as part of a broader performance.
Each Gemini kit contains five (5) tiny sensors and one (1) receiver that the performer has on their person, usually in a pocket. Each of the five sensors has an assigned number (1-5) and, if activated, will signal the performer which one was activated through the receiver using the same number of short vibrations. In this way the performer knows exactly what sensor was triggered at exactly the moment it is triggered.
We chose the name Gemini because the sensors can work in two different ways: either as a magnetic sensor or as a tilt activated sensor, and can be changed between these two modes with a simple switch. This way your Gemini unit provides maximum versatility, allowing you to perform very different routines with one convenient device. For a more through explanation of how these two modes work and the types of routines possible with Gemini, watch the short videos below.
- A set of 5 transmitters (5cm x 1.5cm x 0.8cm); each one is switchable between tilt-activated and magnet-activated modes
- A set of magnets
- All the necessary batteries (plus extras)
- Stand-by battery life of 24 hours
- “Quick-start” instruction booklet to get y going right away
- Access to a secret page on this website that includes:
