Good resource for non-math minds like me!

Purchased this text to study for a CLEP exam, I'm very pleased, layout is great. Teaches one concept at a time, building on concepts , and includes real life examples of when these concepts would actually be used.

This book has forever changed how I view organization and the curation of intentional living spaces. I highly recommend it.

I’m taking MIT ocw single variavle calculus now, and I found I need some books to help with studying. I know Stewart or Thomas calculus is famous for calculus. But I think it’s too huge. And that’s the reason why I have tried to take online lecture. So could you please recommend some calculus books to practice exercises? I want a books which are not huge like Stewart, have some challenge problems, not much focused on analysis. I read some people recommend books, but I think it’s more focused on analysis than calculus.

I have an upcoming statistics exam and I'm studying it on my own. I was recommended Hogg's Introduction to Mathematical Statistics, but I didn't find it helpful. I just want a book which covers basic mathematical statistics and statistical inference: stochastic convergence, estimation of parameters, testing hypothesis, etc. all at an elementary level (suitable for a math undergraduate), with good introduction to the required background for such concepts. Can you provide me a good source?
|
To give you some background, I have a grasp on the basics of statistics and probability theory and even remember touching Bayes theorem at the university data mining course. But being a few years away from the university made my math got extremely rusty (so much for last-minute pre-exam cramming). While I remember various random basic concepts, there are a lot of gaps in my understanding of them. What would be a good material (a book, a site, or otherwise equally accessible medium) to revise the fundamentals and go beyond basics? I'd like a book that can be actually read as a book (most statistics books are really dry and are close to being reference material, rather than a book).
|
Is there consensus in the field of statistics that one book is the absolute best source and completely covering every aspect of GLM - detailing everything from estimation to inference?

What are the prerequisites for studying modern algebraic geometry?

I wonder how much abstract algebra do I need to learn in order to learn algebraic geometry . Possibly , some reference of algebraic geometry books will much helpful . Another thing I see a lot in lecture notes on introductory algebraic geometry is the usage of angle brackets , i suppose they something completely different . What do they mean , anyway ?

My motivation for studying Hopf algebras is twofold: I'm interested in representation theory and the algebraic structure of group rings. I will also take a course on algebraic groups soon and I think it would be helpful to know about Hopf algebras for that. So I'm looking for a good introductory book on Hopf algebras for self-study and especially for one that has many examples and applications to the two topics mentioned above. (As for my background, I know abstract algebra, commutative algebra and non-commutative algebra at a basic graduate level, I'm familiar with the basics on representation theory of (mostly finite) groups and category theory (including monoidal and symmetric monoidal, but not braided monoidal categories) and have some rudimentary knowledge of algebraic geometry. I know almost nothing about Lie algebras.)
|
I want to learn more about hopf algebras but I am having trouble finding a down to earth introduction to the subject with lots of motivation and examples. My algebra knowledge ranges from Dummit and Foote, Atiyah-Macdonald commutative algebra, and Hartshorne level algebraic geometry. What are good places to look at for a hopf algebra beginner? My main motivation is for studying groupoid schemes from an algebraic point of view.

What is the shortest route to the equivalent knowledge to a top notch BS statistics degree and how do I measure when I have achieved that. If a list of books would suffice (assuming I do the exercises lets say), that's terrific. Yes, I expect working out problems to be an implicit part of learning it but I want to fast track as much as realistically possible. I am not looking for an insanely rigorous treatment unless that is part of what statistical majors generally learn.

Points to be noted: I really don't like the way textbooks are written so please no "textbooks" I am COMPLETELY beginner in calculus. I know a little bit of trigonometry and what functions are but not really in depth.The book should start from the base, I mean really from the base. I may require a precalculus book too if the books don't cover that. I would really love if the book shows how calculus was developed, why it was developed and things like that.

I'd read the ASP.NET book first. There is a lot of stuff based around the .Net Class library that you need to know to effectively do any .Net programming, but the VB.Net book is going to spend a lot of time showing you how to create Windows-based applications, and it sounds like you're primarily interested in web programming. Keep the VB.Net book around, though - it will probably come in handy as a reference guide.

This paper describes the development and main operational capabilities of a PC-based, geospatially enabled software that can fuse and visualize large, multi-variable data sets that change in space (x, y, z) and time (t). The new software has the ability to simultaneously visualize imagery, bathymetry/terrain, and true volumetric (voxel) data in a fully interactive geo-referenced mode. In addition to providing global coverage, a key feature of this software is the capability to interactively visualize large data sets while operating on a desktop PC. This is achieved by using tiling and Level Of Detail (LOD) technology for terrain, imagery, and volumetric data as well as compression techniques and the multithreading capabilities of modern PCs.

Benefits of information visualization systems for administrative data analysts
|
We report results from a study on the adoption of an information visualization system by administrative data analysts. Despite the fact that the system was neither fully integrated with their current software tools nor with their existing data analysis practices, analysts identified a number of key benefits that visualization systems provide to their work. These benefits for the most part occurred when analysts went beyond their habitual and well-mastered data analysis routines and engaged in creative discovery processes. We analyze the conditions under which these benefits arose, to inform the design of visualization systems that can better assist the work of administrative data analysts.

The leaching of szaibelyite ore in NaOH solution to prepare sodium metaborate dihydrate was investigated in a batch reactor. The effects of the reaction temperature, NaOH concentration and liquid to solid ratio on the leaching rate have been evaluated and the conversion of boron could reach 95% in 2 h under the optimum reaction conditions. There were two distinct stages in the leaching process and kinetics of both stages followed shrinking core model. The activation energy of stage one (initial 30 min) and stage two (30-120 min) was estimated to be 41.57 kJ/mol and 40.41 kJ/mol, respectively. The kinetics analysis showed that the leaching process was controlled by chemical reaction. (C) 2015 Elsevier B.V. All rights reserved.

In this study, strontium nitrate extraction from celestite in nitric acid solutions was investigated using the leaching method. The influences of acid concentration, solid-to-liquid ratio, stirring speed, and reaction temperature on the leaching of strontium from celestite concentrate were studied. The results showed that the leaching rate increased with increasing acid concentration, stirring speed, and temperature and decreased with increasing solid-to-liquid ratio. The particle size was fixed in all of the dissolution experiments. The results showed that the stirring speed and the temperature were the most influential parameters with respect to the leaching process. The kinetic model best fit control by diffusion through the product layer. The activation energy of the dissolution celestite in nitric acid solutions was calculated to be 42.22 kJ/mol.

The resources of refractory gold ores are abundant, and their effective treatment can bring good economic benefits. This paper investigated the kinetics of leaching gold from refractory gold ores by ultrasonic-assisted electro-chlorination. The effects of ultrasound time ratio, initial hydrochloric acid concentration and leaching temperature on the kinetic parameters were discussed. It is found that the leaching ratio goes up with all the factors increasing. The reaction kinetics is controlled by diffusion. When ultrasound improves the diffusion by reducing the diffusion resistance, the activation energy increases to 37.1 kJ/mol.

SUMMARY. 1. A new experimental method for the study of kinetics and mechanism of reactions at the solid-liquid interface has shown that the dissolution of calcite in acidic waters is, under conditions of high mass transport, controlled by the first order heterogeneous reaction of H+ at the interface and not by diffusion as previously thought. ::: ::: ::: ::: 2. The implications of this for lake liming strategies (aimed at countering the effects of ‘acid rain’) are significant in that under typical liming conditions, the rate of calcite dissolution will be surface controlled and consequently appreciably slower than previously considered.

[1] This investigation focuses on the use of microbially induced calcium carbonate precipitation (MICP) to set up subsurface hydraulic barriers to potentially increase storage security near wellbores of CO2 storage sites. A numerical model is developed, capable of accounting for carbonate precipitation due to ureolytic bacterial activity as well as the flow of two fluid phases in the subsurface. The model is compared to experiments involving saturated flow through sand-packed columns to understand and optimize the processes involved as well as to validate the numerical model. It is then used to predict the effect of dense-phase CO2 and CO2-saturated water on carbonate precipitates in a porous medium.

We used a standardized canine polytrauma model (bone fracture, soft-tissue injury, and hypovolemia), either with or without reinfusion, to study granulocyte accumulation in lung, liver, and muscle tissue. Infusion of radioactively labeled granulocytes revealed significant leukostasis in the lung after the shock procedure, which was more prominent in the group without reinfusion. There was only moderate leukostasis in the liver, while granulocytes were absent from muscle tissue. These radioactive data were in good agreement with the morphologic findings of electron microscopy. Thus, although there was capillary endothelial swelling in all three organs, edema in the muscle endothelial cells of reperfused animals was not due to granulocyte action.

Introduction ::: Bilirubin is well-recognized marker of hepatic dysfunction in intensive care unit (ICU) patients. Multiple organ failure often complicates acute respiratory distress syndrome (ARDS) evolution and is associated with high mortality. The effect of early hepatic dysfunction on ARDS mortality has been poorly investigated. We evaluated the incidence and the prognostic significance of increased serum bilirubin levels in the initial phase of ARDS.

Summary In the pilot study, a new geomodeling technology is presented for developing 3D heterogonous geomodels for Athabasca McMurray (MCMR) oil sands. The geomodels were used to simulate SAGD thermal recovery. Both conventional SAGD completions and SAGD with ICD completions were tested. The simulation results show that for a heterogeneous Athabasca McMurray oil sand reservoir, the ICD completion technology enhances oil production and reduces steam consumption. As a result, the economics of SAGD recovery from the heterogeneous sands is improved.

The saturation magnetization study and first-principles calculation Of Fe-Si-Al
|
Sendust alloy (Fe-Si-Al) flaky particles were used as microwave absorbing material because of its excellent soft magnetic properties such as high saturation magnetization, high permeability, low magnetocrystalline anisotropy, and nearly zero magnetostriction.[1] The structure of FeSiAl alloy is similar to that of FeAl alloy; O. Ikeda etc.[2] studied the transformation among A2, B2 and DO3 structures. The electromagnetic and microwave absorption properties of the composites employing FeSiAl alloy powders with different phase structure, as shown in Figure 1, were investigated. The magnetic moment of the different phase structure were calculate by the First-principles calculation. The results showed that the phase structure had significant influence on the saturation magnetization (Ms).

Influence of TEM low energy electron irradiation on InP damage structure irradiated previously by 100 keV Au ions
|
The behavior of disordered isolated volumes (zones) in InP under electron action was characterized by TEM observations. The total areal fraction of the disordered zones in initial InP pre-irradiated by 100 keV heavy Au ions decreased as a function of irradiating electron fluence (time of TEM electron beam irradiation) within all the investigated electron energy range (100–300 keV), Disappearance of disordered zones shows that these zones are sensitive to electron beam irradiation and recover even under electron energies not sufficient to directly elastically displace lattice atoms In and P.

Finding environmentally gentle methods to graft Lewis acid on the surface of mesoporous materials is a topic of current interest. Herein we describe the optimization of a preparation procedure of a mesoporous silica-supported ErIII catalyst using the microwave-assisted post-calcination functionalization of Mobil Composition of Matter-41 silica as the key step. The required time for functionalization was reduced from several hours to 10 min using sealed-vessel microwave technology. Control experiments using conventional heating at the same temperature demonstrated that the rate increase is owing to a simple thermal/kinetic effect as a result of the higher reaction temperature. The resulting ErIII catalyst was tested for the first time as a catalyst in the continuous flow deprotection of benzaldehyde dimethylacetal and a complete leaching study was performed.

Theoretical study of pump absorption of colinear side-pumping coupler with pumping and absorption loops
|
The results of a theoretical study of pump absorption properties in the colinear side-pumping schemes with pumping loops and absorption loops are presented. For side-pumping schemes with pumping loops, the number of pumping loops affects the pump absorption obviously: the more pumping loops, the higher pump absorption; and the pump light is absorbed effectively after propagating through all the loops. For side-pumping schemes with absorption loops, more loops results in a larger doped region, which leads to higher pump absorption efficiency.

HYDROGEN DIFFUSION IN AMORPHOUS FeCrB RIBBONS
|
The article deals with the study of hydrogen absorption (hydrogenation) and desorption (dehydrogenation) in amorphous ferromagnetic FeCrB ribbons prepared by rapid quenching from the melt. A simple theoretical model was proposed for description of hydrogen concentration and determination of diffusion coefficient in these materials. Using this model diffusion coefficient can be calculated using experimentally obtained values of average hydrogen concentration in the sample during dehydrogenation process. The values of diffusion coefficients are comparable with those obtained by hydrogen permeation test. The proposed method is not only simple but it also makes possible to determine diffusion coefficient under the same conditions as the changes of other properties of these materials during their dehydrogenation.

The complexation of iron by marine humic acid
|
Abstract Cation exchange capacity measurements, performed before and after removal of humic acid from Narragansett Bay sediments, indicate that low concentrations of these organic substances strongly influence the ability of the sediment to react with metal ions. Atomic absorption and spectrophotometric methods allow quantitative determination of the extent of reaction between a naturally occurring humic acid and iron in artificial seawater. Humic acid-iron complexes are formed whose solubilities depend on the humic acid-iron ratio used in the experiment. This study suggests that humic acid is a transporting agent for trace metals in a marine environment.

The aim of this research was the determination of adsorption and desorption isotherms of cow whole milk powder. The experiments have been carried out at 15, 25 and 40 oC, in ranges of moisture and water activity characteristic of normal conditions in which the processes of drying, packaging and storage are developed. By studying the influence of the temperature on the experimental plots, the isosteric adsorption heat was determined. Experimental data were correlated to the referential model of Guggenheim, Anderson and Boer (GAB). For both, adsorption and desorption, a good model fit was observed. The isotherms showed very similar shapes between them and, by comparing adsorption and desorption isotherms, the phenomenon of hysteresis was confirmed.

Anaerobic Treatment of Viscose Wastewater
|
The waste water from the viscose production process can be characterized as follows: low to medium strength of biodegradable carbonaceous matter, high concentrations of sulfate, high concentrations of zinc. ::: ::: The treatment process to be presented consists of anaerobic pre-treatment of the neutralized waste water combining the removal of carbonaceous matter with zinc removal by sulfide precipitation. The organic pollution of the waste water is used as a substrate for sulfate reducing bacteria present in the anaerobic reactor. The hydrogen sulfide produced precipitates the zinc as insoluble zinc sulfide. Labscale experiments lasting several months resulted in stable zinc effluent concentrations below 1 mg/l combined with a COD removal of about 40 - 50 %.

Abstract Both fibroin-based and sericin-based biomaterials have been studying extensively due to their wide applications, however the extraction of either fibroin or sericin protein is extremely complicated. Here we prepare the protein solution directly from alive silkworms instead of extracting proteins from silkworm silk. The protein solution and the polyvinyl alcohol solution are mixed in different weight ratios to produce silkworm-based silk fibers, which have many special properties like high mechanical strength and good wetting property. The new production has potential applications as a new textile fabric or a new bio-inspired material.

One of the fundamental steps to the successful operation of biomass gasification technologies for power generation is the efficiency of the gas cleaning step. Catalytic cracking is selected as the hot gas cleaning technology for this research using zeolite HZSM-5 catalyst in order to reduce tar produced from palm shells gasification in the laboratory scale fixed bed gasifier. The catalyst load of 2, 5 and 10 weight % of the weight of palms shells has been tested in experiment. Gas chromatographic analysis of the tar produced has been conducted along with the study of biomass gasification index (BGI), emissions of CO, NO, and SO2. Furthermore, suitable correlations for the tar removal cleanup for syngas derived from biomass palm shells at different operating parameters when using HZSM-5 catalyst have been developed from the interpolation of the experimental data obtained.

Narrow growth window for stoichiometric, layer-by-layer growth of LaAlO 3 thin films using pulsed laser deposition
|
Abstract We study the structure and surface morphology of the 100 nm homoepitaxial LaAlO 3 films grown by pulsed laser deposition in a broad range of growth parameters. We show that there is a narrow window of growth conditions in which the stoichiometric, bulk-like structure is obtained while maintaining a 2-dimensional (2D) layer-by-layer growth mode. In our system, these optimum growth conditions are 100 mTorr background pressure with laser energy density 1.5–2 J/cm 2 . The sensitivity to growth conditions of the stoichiometry and structure of LaAlO 3 films can have a crucial role in the 2-D electron gas formed at the LaAlO 3 /SrTiO 3 interface.

Surface complexation modeling of U(VI) sorption on GMZ bentonite in the presence of fulvic acid
|
In this work, experiments and modeling for the interactions between uranyl ion and GMZ bentonite in the presence of fulvic acid are presented. The results demonstrated that FA is strongly bound to GMZ bentonite, and these molecules have a very large effect on the U(VI) sorption. The results also demonstrated that U(VI) sorption to GMZ bentonite in the presence and absence of sorbed FA can be well predicted by combining SHM and DLM. According to the model calculations, the nature of the interactions between FA with U(VI) at GMZ bentonite surface is mainly surface complex. The first attempt to simulate clay interaction with humus by the SHM model.

The theory of reinforcement learning (RL) was originally motivated by animal learning of sequential behavior, but has been developed and extended in the field of machine learning as an approach to Markov decision processes. Recently, a number of neuroscience studies have suggested a relationship between reward-related activities in the brain and functions necessary for RL. Regarding the history of RL, we introduce in this article the theory of RL and present two engineering applications. Then we discuss possible implementations in the brain.

In this article, we propose and analyze a class of actor-critic algorithms. These are two-time-scale algorithms in which the critic uses temporal difference learning with a linearly parameterized approximation architecture, and the actor is updated in an approximate gradient direction, based on information provided by the critic. We show that the features for the critic should ideally span a subspace prescribed by the choice of parameterization of the actor. We study actor-critic algorithms for Markov decision processes with Polish state and action spaces. We state and prove two results regarding their convergence.

Exploiting generalisation symmetries in accuracy-based learning classifier systems: An initial study
|
Modern learning classifier systems typically exploit a niched genetic algorithm to facilitate rule discovery. When used for reinforcement learning, such rules represent generalisations over the state-action-reward space. Whilst encouraging maximal generality, the niching can potentially hinder the formation of generalisations in the state space which are symmetrical, or very similar, over different actions. This paper introduces the use of rules which contain multiple actions, maintaining accuracy and reward metrics for each action. It is shown that problem symmetries can be exploited, improving performance, whilst not degrading performance when symmetries are reduced.

Abstract The paper is concerned with a reduced SIR model for migrant workers. By using differential inequality technique and a novel argument, we derive a set of conditions to ensure that the endemic equilibrium of the model is globally exponentially stable. The obtained results complement with some existing ones. We also use numerical simulations to demonstrate the theoretical results.

Improving nanoelectronic designs using a statistical approach to identify key parameters in circuit level SEU simulations
|
One of the key challenges in nanoelectronics design is the decreasing reliability due to radiation induced single-event upsets. Without detailed device level simulations or physical experimentation, circuit level models can generate misleading reliability information. We present the results from a screening experiment to identify significant parameters in circuit level SEU simulations. We show that cell supply voltage, sizing parameters, and transient waveform descriptions have an important impact on design and should therefore be considered with care in circuit level designs. Larger variations in parameters can lead to soft error rate estimates that vary by more than 4 orders of magnitude, even small variations can lead to 15times variation in soft error rate estimation for a design. We present our methodology for screening and a ranking based on significance of several parameters involved in soft error simulation at the SPICE level.

We present a method for synthesising control strategies for continuous dynamical systems. We use Uppaal Tiga for the synthesis in combination with a set-based Euler method for guaranteeing that the synthesis is safe. We present both a general method and a method which provides tighter bounds for monotone systems. As a case-study, we synthesize a guaranteed safe strategy for a simplified adaptive cruise control application. We show that the guaranteed strategy is only slightly more conservative than the strategy generated in the original adaptive cruise control paper which uses a discrete non guaranteed strategy. Also, we show how reinforcement learning may be used to obtain optimal sub-strategies.

Towards robot-assisted vitreoretinal surgery: Force-sensing micro-forceps integrated with a handheld micromanipulator
|
In vitreoretinal practice, controlled tremor-free motion and limitation of applied forces to the retina are two highly desired features. This study addresses both requirements with a new integrated system: a force-sensing motorized micro-forceps combined with an active tremorcanceling handheld micromanipulator, known as Micron. The micro-forceps is a 20 Ga instrument that is mechanically decoupled from its handle and senses the transverse forces at its tip with an accuracy of 0.3 mN. Membrane peeling trials on a bandage phantom revealed a 60–95% reduction in the 2–20 Hz band in both the tip force and position spectra, while peeling forces remained below the set safety threshold.

This paper describes an on-line method for building e-insensitive support vector machines for regression as described in [12]. The method is an extension of the method developed by [1] for building incremental support vector machines for classification. Machines obtained by using this approach are equivalent to the ones obtained by applying exact methods like quadratic programming, but they are obtained more quickly and allow the incremental addition of new points, removal of existing points and update of target values for existing data. This development opens the application of SVM regression to areas such as on-line prediction of temporal series or generalization of value functions in reinforcement learning.

Combinatorial approach to inference in partially identified incomplete structural models: Inference in games
|
We propose a computationally feasible inference method in finite games of complete information. Galichon and Henry, 2011 and Beresteanu, Molchanov, and Molinari, 2011 show that the empirical content in such models is characterized by a collection of moment inequalities whose number increases exponentially with the number of discrete outcomes. We propose an equivalent characterization based on classical combinatorial optimization methods that allows the construction of confidence regions with an efficient bootstrap procedure that runs in linear computing time. The method can be applied to the empirical analysis of cooperative and noncooperative games, instrumental variable models of discrete choice, and revealed preference analysis. We propose an application to the determinants of long term elderly care choices.

Methods for Shallow Landslides Susceptibility Mapping: An Example in Oltrepo Pavese
|
The principal aim of this study is to compare different landslide susceptibility zonation models for predicting areas prone to shallow landsliding using both physically distributed landslide models and artificial neural networks. Necessary geotechnical and hydrological parameters were obtained coupling sample laboratory analysis and in situ measures; soil thickness was estimated using an empirical model while distribution of rainfall intensity was analyzed by performing a spatial interpolation. The predictive capabilities of these models were finally evaluated using a threshold-independent quantitative method (the ROC plot).

This paper investigates the use of reinforcement learning for the navigation of an over-actuated marine platform in unknown environments. The proposed approach uses an online least-squared policy iteration scheme for value function approximation in order to estimate optimal policy. We evaluate our approach in a simulation platform and report some initial results concerning its performance on estimating optimal navigation policies to unknown environments under different environmental disturbances. The results are promising.

Foundations of human problem solving
|
Despite great strides in both machine learning and neuroscience, we do not know how the human brain solves problems in the general sense. We approach this question by drawing on the framework of engineering control theory. We demonstrate a computational neural model with only localist learning laws that is able to find solutions to arbitrary problems. Using a combination of computational neural modeling, human fMRI, and representational similarity analysis, we show here that the roles of a number of brain regions can be reinterpreted as interacting mechanisms of a control theoretic system. The results suggest a new set of functional perspectives on the orbitofrontal cortex, hippocampus, basal ganglia, anterior temporal lobe, lateral prefrontal cortex, and visual cortex, as well as a new path toward artificial general intelligence.
