could hydrogen an atoms be arranged differently? | Definitely, it is possible to arrange hydrogen differently.\n\nThe first way hydrogen can be arranged is in the type of isotopes. There are three different kinds of hydrogen:\nProtium (1 proton, 0 neutron, 1 electron)\nDeuterium (1 proton, 1 neutron, 1 electron)\nTritium (1 proton, 2 neutrons, 1 electron)\n\nAdditionally, how hydrogen is arranged at current atmospheric pressures and temperatures is as a diatomic gas that shares between them two electrons. At lower temperatures and higher pressures, hydrogen can become a liquid, and a solid.\n\nAt extremely high pressures (like GPa and above), the properties of hydrogen change so drastically that it becomes a metallic solid. | Are you looking at any protein in particular? Look up in situ hybrdization for proteins ( at least it will give you an idea where it is localised). I think that it would really depend on the system ad proteins that you want to study, so I am not sure how much else I can tell you, sorry. | eng_Latn | 58,043 |
what is electron bifurcation | Electron diffraction is most frequently used in solid state physics and chemistry to study the crystal structure of solids. Experiments are usually performed in a transmission electron microscope (TEM), or a scanning electron microscope (SEM) as electron backscatter diffraction.his phenomenon is commonly known as waveâparticle duality, which states that a particle of matter (in this case the incident electron) can be described as a wave. For this reason, an electron can be regarded as a wave much like sound or water waves. | As the electrons are not divided equally after bond cleavage this is called Heterolytic Fission. In a case the C atom carries a positive charge it is called a carbocation and in the case it carries both the electrons of the broken bond and is negatively charged, it is quite intuitively called a Carbanion.hese are intermediates also formed as a result of heterolysis, but here the electron pair from the bond is kept by the carbon atom. From what we saw earlier the more electronegative atom keeps the electrons, so in this case carbon must the more electronegative of the two atoms making up the bond. | eng_Latn | 58,180 |

Adaptive control for car like vehicles guidance relying on RTK GPS: rejection of sliding effects in agricultural applications | Numerous agricultural applications require very accurate guidance of farm vehicles. Current works have established that RTK GPS was a very suitable sensor in order to meet the expected precision: several control laws have been designed for vehicles equipped with such a sensor, and satisfactory results have been achieved as long as vehicles do not slide. Nevertheless, in actual working conditions (sloping fields, entering into curves on a wet land, etc.), sliding inevitably occurs. In this paper, we design a nonlinear adaptive control law in order to preserve guidance precision in presence of sliding: realtime sliding estimation is used to correct vehicle evolution. Field experiments, demonstrating the capabilities of that control scheme are reported and discussed. | A new estimator for a four-element plane array is introduced in order to get acoustic-passive direction estimation of targets.We concern much about the performance of the estimator under a two-target situation.In this paper,the two targets concerned are of the same type of acoustic source.Under different signal to interfere ratios,we propose the change of the precision of the direction estimation as the angle between the two targets changes.Our study was done under the real time Warfield situation,and may help the design of small acoustic-passive direction estimation arrays. | eng_Latn | 58,228 |
Design and convergence of iterative learning control based on neural networks | The purpose of this study is to develop an effective approach to control design for repetitive nonlinear processes based on the iterative learning control technique. The idea adopted here to circumvent the inherent uncertainty of the controlled system modelling is to enhance the iterative learning scheme with neural networks used for controller design and error estimation. In result, we obtain the iterative control update rule, which can be calculated based on efficient data-driven technique for training neural network. Finally, the proposed approach is illustrated on the application example to nonlinear pneumatic servomechanism. | We consider asymptotic behavior of partial sums and sample covariances for linear processes whose innovations are dependent.

A projection neural network with mixed delays for solving linear variational inequality | This paper presents a projection neural network with discrete delays and distributed delays (i.e. mixed delays) for solving linear variational inequality (LVI). By the Lyapunov theory and the linear matrix inequality (LMI) approach, the neural network is proved to be globally exponentially convergent to the solution of LVI. Compared with existing neural networks for solving LVI, the proposed one features the ability of solving a class of non-monotone LVI. One numerical example is provided to illustrate the effectiveness and the satisfactory performance of the neural network. | We describe preliminary results from an effort to quantify the uncertainties in parton distribution functions and the resulting uncertainties in predicted physical quantities.

The work presented examines the feasibility of using artificial neural networks (ANNs) and evolutionary algorithms (EAs) to model fault free and faulted switched reluctance motor (SRM) drive systems. SRMs are capable of functioning despite the presence of faults. Faults impart transient changes to machine inductances in a manner that is difficult to model analytically. After this transient period, SRMs are capable of functioning at a reduced level of performance. ANNs are applied for their well known interpolation capabilities for highly nonlinear systems. EAs are employed for their ability to search a complex structural and parametric space as necessary to find good ANN solutions. In this paper, the ANN structure and training regimen are described for application to an example SRM drive system under normal and abnormal operating conditions. > | Control techniques for electrical machines have been applied for many years to what are called electrical drives (EDs) or adjustable speed drives (ASDs), which are part of almost 25% of applications of electrical machines in the industry. Therefore, this technology has followed the evolution of performances of both power converters and electrical actuators or generators for more than 50 years and the invention of silicon-controlled rectifiers. The aim of this article is not to cover a survey of EDs or ASDs since it has already been covered recently [1] but rather to present trends of the control part related to this technology. Of course, the control part is fully dependent of the power part and cannot be treated as a stand-alone technique. | Closed-form expressions for the statistics of the harmonic mean of two independent and identically distributed gamma variates are presented. The probability density function of the harmonic mean of two F variates is also derived. These statistical results are then applied to study the performance of wireless communication systems with nonregenerative relays over flat Nakagami fading channels. More specifically, outage probability formulas for noise-limited systems as well as systems affected by interference are obtained. Furthermore, general expressions for average bit-error rates are also derived. Finally, comparisons between regenerative and nonregenerative systems are presented. Numerical results show that the former systems clearly outperform the latter ones for low average signal-to-noise ratios (SNRs). They also show that the two systems have similar performance at high average SNRs. | eng_Latn | 59,782 |

A Problem and Solution of the Motion Control System | Abstract The "Rainbow" is a fully submerged hydrofoil catamaran and has a motion control system named APF (Auto Pilot on Foils). Although the original APF could eliminate wave-excited motions, there remained a certain level of vibration. To reduce the vibration, some improvements were enforced on the APF for the "Rainbow 2" . The effectiveness of the improvements were verified during the sea trials of the "Rainbow 2" , and it was clarified that the vibration levels of the "Rainbow 2" were reduced to about 10% of those of the original "Rainbow" . | The paper presents an analytical approach to extract machine parameters for creating a machine model under stator turn fault condition for a surface permanentmagnet (SPM) motor.

Extremum seeking control with fractional-order switching technique design for maximum power point tracking in photovoltaic systems | This paper considers a novel extremum seeking control with fractional-order switching technique (ESC-FOST) as a maximum power point tracking (MPPT) algorithm for a PV system. The proposed ESC-FOST combines extremum seeking controller with FO sliding mode dynamics, in which FO proportional-integral (PI) switching surface is adopted. The ESC-FOST can not only guarantee the output power is maintained around the maximum power point but that it will also have a faster tracking performance and higher accuracy than the ESC with integer-order switching technique (ESC-IOST). Simulation and experimental results demonstrate the effectiveness and benefit of the ESC-FOST for the PV plant. | The paper presents an analytical approach to extract machine parameters for creating a machine model under stator turn fault condition for a surface permanentmagnet (SPM) motor.

Current Sensorless Model Free Control Applied on PMSM Drive System | In control of electric machines, removing the current sensors from the electric powertrains has a great importance owing to saving on manufacturing and maintenance costs. This paper addresses the Model-Free-Controller (MFC) as a current sensor-less controller that do the control task for a Permanent-Magnet-Synchronism-Machine (PMSM) without using neither sensor nor estimator for stator current. As this controller is model free, it doesn't require any information about parameters. MFC tries to control the drive system just with measuring the rotor speed and dc bus voltage. Simulation study has been done to show the MFC's robustness under ideal and parametric error condition. | The leading part of electroweak radiative corrections to the Drell-Yan process in the CMS (compact muon solenoid detector) experiment at LHC were calculated. Analytic and numerical tests indicate that the results are independent of all nonphysical parameters. A numerical analysis of radiative effects was performed by using the FORTRAN code READY with allowance for experimental constraints at the CMS detector. The results presented for the relative correction to the fully differential cross section for the Drell-Yan process over the entire kinematical region of the CMS detector would hopefully be helpful in handling experimental data. | kor_Hang | 59,884 |
PP.31.18: ASSOCIATION BETWEEN ABNORMAL ORTHOSTATIC BLOOD PRESSURE CHANGE AND DAY-TO-DAY BLOOD PRESSURE VARIABILITY | Objective:Orthostatic blood pressure (BP) change, BP reactivity, has been reported to be associated with cardiovascular events. Day-to-day variability assessed by home BP monitoring, one of the BP variability, has also provided significant contribution to risk stratification. Although these BP indic | This paper investigates the nonlinear characteristic between voltage phase and torque and proposes a model-based design of voltage phase controller. PMSM drive systems should realize a quick torque response and have a wide operating range. However, in high-speed region, the control input is voltage phase only and the plant is nonlinear due to the inverter output voltage amplitude saturation. Because of this nonlinear characteristic between current and voltage phase, model-based design have not yet been carried out. As basic study, this paper proposes a model-based voltage phase controller for SPMSM. Simulation results and experimental results show the effectiveness of the model-based design method. In addition, the analysis of the derived plant model shows the relationship between q-axis current and voltage phase is a non-minimum phase system. | yue_Hant | 59,885 |

Giant magneto and anisotropic resistance in an epitaxial (110) DyFe2/YFe2 multilayer film | Abstract Anisotropic and giant magneto-resistance (AMR and GMR) measurements for a molecular beam epitaxy grown (1 1 0) multilayer film [50 A-DyFe 2 /50 A-YFe 2 ]×40 at 100 K are reported. The film possesses a bending field B B ∼5 T and an irreversible switching field B IS ∼5 T. These features allow the study of both AMR, and GMR caused by the creation not only of longitudinal but also transverse magnetic exchange springs, in the magnetically soft YFe 2 layers. Finally, rotation experiments in applied fields show that like DyFe 2 films, there is a metastable state aligned along a [ 1 1 0] axis at 100 K. | This paper presents a synchronous reluctance machine design for high-speed high-power applications, such as the motor/alternator for a flywheel energy storage system.

What military leader does the term Pyrrhic victory come from? | Despite early victories, Pyrrhus found his position in Italy untenable. Rome steadfastly refused to negotiate with Pyrrhus as long as his army remained in Italy. Facing unacceptably heavy losses from each encounter with the Roman army, Pyrrhus withdrew from the peninsula (hence the term "Pyrrhic victory"). In 275 BC, Pyrrhus again met the Roman army at the Battle of Beneventum. While Beneventum was indecisive, Pyrrhus realised his army had been exhausted and reduced by years of foreign campaigns. Seeing little hope for further gains, he withdrew completely from Italy. | The Prussian General Staff developed by Moltke proved to be extremely effective, in contrast to the traditional French school. This was in large part due to the fact that the Prussian General Staff was created to study previous Prussian operations and learn to avoid mistakes. The structure also greatly strengthened Moltke's ability to control large formations spread out over significant distances. The Chief of the General Staff, effectively the commander in chief of the Prussian army, was independent of the minister of war and answered only to the monarch. The French General Staff—along with those of every other European military—was little better than a collection of assistants for the line commanders. This disorganization hampered the French commanders' ability to exercise control of their forces. | eng_Latn | 63,869 |

Hence the seismic effects in Italy “can be considered as historical variables of the degree of intensity: historical building techniques, economic levels and population size”. In recent years, the Department of Civil Protection (DPC) evidenced that the high economic losses due to the strong earthquakes occurred in Italy up to 2003 rapidly increase over time due to the rapid urbanization of several portions of the territory. According to these concerns, the present study focuses on microzoning studies in the Aterno Valley after the 2009 L’Aquila earthquake. The authors show the role played by geo-lithological conditions in the amplification effects occurred at different sections of the Aterno Valley and discuss the efficiency of some geophysical techniques to characterize the local seismic response at the site. | Aiming at Shenyang Metro in construction,analysis of influence of advance small duct grouting on metro tunnel excavation is conducted.By different layout in ring of small duct,based on surrounding rock stress and displacement of each monitored point of tunnel,the rational layout is given.which has important reference meaning to similar tunnel engineering. | eng_Latn | 64,369 |
What did a professor at the Peking University say about the handling of the earthquake? | Rescue efforts performed by the Chinese government were praised by western media, especially in comparison with Myanmar's blockage of foreign aid during Cyclone Nargis, as well as China's previous performance during the 1976 Tangshan earthquake. China's openness during the media coverage of the Sichuan earthquake led a professor at the Peking University to say, “This is the first time [that] the Chinese media has lived up to international standards”. Los Angeles Times praised China's media coverage of the quake of being "democratic". | Despite the calamity and huge death toll, Lisbon suffered no epidemics and within less than one year was already being rebuilt. The new city centre of Lisbon was designed to resist subsequent earthquakes. Architectural models were built for tests, and the effects of an earthquake were simulated by marching troops around the models. The buildings and big squares of the Pombaline City Centre still remain as one of Lisbon's tourist attractions. Sebastião de Melo also made an important contribution to the study of seismology by designing an inquiry that was sent to every parish in the country. | eng_Latn | 64,379 |

how is a richter scale used | The Richter scale is a standard scale used to compare earthquakes. It is a logarithmic scale, meaning that the numbers on the scale measure factors of 10. So, for example, an earthquake that measures 4.0 on the Richter scale is 10 times larger than one that measures 3.0. On the Richter scale, anything below 2.0 is undetectable to a normal person and is called a microquake. Microquakes occur constantly. Moderate earthquakes measure less than 6.0 or so on the Richter scale. Earthquakes measuring more than 6.0 can cause significant damage. | The Richter Scale. Figure 1 - Charles Richter studying a seismogram. There are a number of ways to measure the magnitude of an earthquake. The first widely-used method, the Richter scale, was developed by Charles F. Richter in 1934. It used a formula based on amplitude of the largest wave recorded on a specific type of seismometer and the distance between the earthquake and the seismometer. | eng_Latn | 64,420 |

What did the professors predict? | The earthquake also provided opportunities for researchers to retrofit data in order to model future earthquake predictions. Using data from the Intermagnet Lanzhou geomagnetic observatory, geologists Lazo Pekevski from the Ss. Cyril and Methodius University of Skopje in Macedonia and Strachimir Mavrodiev from the Bulgarian Academy of Sciences attempted to establish a "time prediction method" through collecting statistics on geomagnetism with tidal gravitational potential. Using this method, they were said to have predicted the time of the 2008 Sichuan earthquake with an accuracy of ±1 day. The same study, however, acknowledges the limitation of earthquake prediction models, and does not mention that the location of the quake could be accurately predicted. | The Black Wednesday economic disaster in September 1992 left the Conservative government's reputation for monetary excellence in tatters, and by the end of that year Labour had a comfortable lead over the Tories in the opinion polls. Although the recession was declared over in April 1993 and a period of strong and sustained economic growth followed, coupled with a relatively swift fall in unemployment, the Labour lead in the opinion polls remained strong. However, Smith died from a heart attack in May 1994. | eng_Latn | 64,485 |

Perry used his superior firepower to force Japan to open its borders to trade. Prior to that only a few harbor towns, under strict control from the Shogunate, were allowed to participate in Western trade, and even then, it was based largely on the idea of playing the Franciscans and Dominicans off against one another (in exchange for the crucial arquebus technology, which in turn was a major contributor to the downfall of the classical samurai). | eng_Latn | 64,492 |
What was the most displacement caused by the earthquake? | According to a study by the China Earthquake Administration (CEA), the earthquake occurred along the Longmenshan fault, a thrust structure along the border of the Indo-Australian Plate and Eurasian Plate. Seismic activities concentrated on its mid-fracture (known as Yingxiu-Beichuan fracture). The rupture lasted close to 120 sec, with the majority of energy released in the first 80 sec. Starting from Wenchuan, the rupture propagated at an average speed of 3.1 kilometers per second 49° toward north east, rupturing a total of about 300 km. Maximum displacement amounted to 9 meters. The focus was deeper than 10 km. | The troops were reembarked and moved to the Bay of St. Lunaire in Brittany where, on 3 September, they were landed to operate against St. Malo; however, this action proved impractical. Worsening weather forced the two armies to separate: the ships sailed for the safer anchorage of St. Cast, while the army proceeded overland. The tardiness of Bligh in moving his forces allowed a French force of 10,000 from Brest to catch up with him and open fire on the reembarkation troops. A rear-guard of 1,400 under General Dury held off the French while the rest of the army embarked. They could not be saved; 750, including Dury, were killed and the rest captured. | eng_Latn | 64,493 |

In the conference report on the 1982 amendments, Congress specified that it intended the San Bruno plan to act "as a model" for future conservation plans developed under the incidental take exemption provision and that "the adequacy of similar conservation plans should be measured against the San Bruno plan". Congress further noted that the San Bruno plan was based on "an independent exhaustive biological study" and protected at least 87% of the habitat of the listed butterflies that led to the development of the HCP. | eng_Latn | 64,529 |
This paper studies conditions influencing the generosity of wealthy people. We conduct incentivized experiments with individuals who have at least €1 million in their bank account. The results show that millionaires are more generous toward low-income individuals in a giving situation when the other participant has no power, than in a strategic setting, where the other participant can punish unfair behavior. Moreover, the level of giving by millionaires is higher than in any other previous study. Our findings have important implications for charities and financial institutions that deal with wealthy individuals. | Community standards of fairness for the setting of prices and wages were elicited by telephone surveys. In customer or labor markets it isacceptable for a firm to raise prices (or cut wages) when profits arethreatened, and to maintain prices when costs diminish. It is unfair toexploit shifts in demand by raising prices or cutting wages. Several market anomalies are explained by assuming that these standards of fairness influence the behavior of firms. Copyright 1986 by American Economic Association. | I study a game in which two players first bid for offshore tracts (below which oil and gas may be present) and next time their drilling decisions. High types bid more aggressively if the auctioneer discloses bids as this gives them useful information about the profitability of drilling. A low type fears that the disclosure of her "low" bid reduces the other player's incentive to drill. Hence, they bid more aggressively if the auctioneer does not disclose bids. If players are sufficiently patient, it is optimal to disclose bids. Otherwise, it may be optimal not to disclose them. | eng_Latn | 64,592 |
