General Theory of Light Propagation and Imaging Through the Atmosphere
This 2nd edition lays out an updated version of the general theory of light propagation and imaging through Earth's turbulent atmosphere initially developed in the late '70s and '80s, with additional applications in the areas of laser communications and high-energy laser beam propagation. New material includes a chapter providing a comprehensive mathematical tool set for precisely characterizing image formation with the anticipated Extremely Large Telescopes (ELTS), enabling a staggering range of star image shapes and sizes; existing chapters rewritten or modified so as to supplement the mathematics with clearer physical insight through written and graphical means; a history of the development of present-day understanding of light propagation and imaging through the atmosphere as represented by the general theory described. Beginning with the rudimentary, geometrical-optics based understanding of a century ago, it describes advances made in the 1960s, including the developmentof the 'Kolmogorov theory, ' the deficiencies of which undermined its credibility, but not before it had done enormous damage, such as construction of a generation of underperforming 'light bucket' telescopes. The general theory requires no a priori turbulence assumptions. Instead, it provides means for calculating the turbulence properties directly from readily-measurable properties of star images.
Crowd Dynamics by Kinetic Theory Modeling
The contents of this brief Lecture Note are devoted to modeling, simulations, and applications with the aim of proposing a unified multiscale approach accounting for the physics and the psychology of people in crowds. The modeling approach is based on the mathematical theory of active particles, with the goal of contributing to safety problems of interest for the well-being of our society, for instance, by supporting crisis management in critical situations such as sudden evacuation dynamics induced through complex venues by incidents.
Relativistic Classical Mechanics and Electrodynamics
This book presents classical relativistic mechanics and electrodynamics in the Feynman-Stueckelberg event-oriented framework formalized by Horwitz and Piron. The full apparatus of classical analytical mechanics is generalized to relativistic form by replacing Galilean covariance with manifest Lorentz covariance and introducing a coordinate-independent parameter ���� to play the role of Newton's universal and monotonically advancing time. Fundamental physics is described by the ����-evolution of a system point through an unconstrained 8D phase space, with mass a dynamical quantity conserved under particular interactions. Classical gauge invariance leads to an electrodynamics derived from five ����-dependent potentials described by 5D pre-Maxwell field equations. Events trace out worldlines as ���� advances monotonically, inducing pre-Maxwell fields by their motions, and moving under the influence of these fields. The dynamics are governed canonically by a scalar Hamiltonian that generates evolution of a 4D block universe defined at ���� to an infinitesimally close 4D block universe defined at ����+��������. This electrodynamics, and its extension to curved space and non-Abelian gauge symmetry, is well-posed and integrable, providing a clear resolution to grandfather paradoxes. Examples include classical Coulomb scattering, electrostatics, plane waves, radiation from a simple antenna, classical pair production, classical CPT, and dynamical solutions in weak field gravitation. This classical framework will be of interest to workers in quantum theory and general relativity, as well as those interested in the classical foundations of gauge theory.

Solutions Manual for IP2e
Steps to solving calculation problems in Introductory Physics, 2nd edition. The Solutions Manual is a useful supplement to students, homeschooling environments, or anyone who would like help with the working out of calculation problems in Introductory Physics. Appropriate for grade-level 9th to 11th grade students, Introductory Physics incorporates math, history, and epistemology alongside the beautiful graphics and lucid text in a modestly-sized volume that students will appreciate. This book was designed for grade-level freshmen, but it is also suitable for physics in the sophomore or junior year. In fact, optional chapters are added for the benefit of schools where physics occurs in 10th or 11th grade and students can move more quickly through the material. Mathematical problems are rigorous and challenging, but only assume that students are taking Algebra I concurrently. The text is not suitable for an upper-level vector/trig physics course; for a vector-based text, see our book Physics: Modeling Nature. A common question we hear goes something like, "Is this text a real physics course?" Understandably, people wonder if a freshman level physics course will "count," will it be a full credit, will students be short-changed. The answer is, Yes, this is a full physics course that counts a full science credit. In fact, if our mastery-learning paradigm is followed, students will know physics better at the end of the course than with any other method.

New Advances of Cavitation Instabilities
Cavitation refers to the formation of vapor cavities in a liquid when the local pressure becomes lower than the saturation pressure. In many hydraulic applications, cavitation is considered as a non-desirable phenomenon, as far as it may cause performance degradation, vibration problems, enhance broad-band noise-emission, and eventually trigger erosion. In this Special Issue, recent findings about cavitation instabilities are reported. More precisely, the dynamics of cavitation sheets are explored at very low Reynolds numbers in laminar flows, and in microscale applications. Both experimental and numerical approach are used. For the latter, original methods are assessed, such as smooth particles hydrodynamics or detached eddy simulations coupled to a compressible approach.

The Great Pyramid and Connections with the Bible
The book is about the work of Dr. Adam Rutherford and his son James Rutherford engineer, and master. Their main result is that the Great Pyramid is in fact "Bible in stone" in Mathematics, and the Egypt measurement is 1,001 British Inch. Therefore understandably British specialist thought that the message of the Great Pyramid is specially to UK and USA as these nations use Inch. USA (Manaseh tribe) and UK (Efraim tribe). These measurements were prior used also in Iceland, and other countries. Because of this Dr. Adam Rutherford got special support from British authorities, and also got support from 20 - 30 best specialist, mostly from UK. The only error in their massive books are End Time calculation織s are wrong, and this is explained thoroughly in this book. The result is agreed by the best specialist. And now going to Ph.D. defense. Isaiah 19.19-20 is clearly showing that the Great Pyramid is "Bible in Stone" or in Mathematics. This is of course very interesting subject and showing behind the today curtains of the World.
Spark
A fresh look at electricity and its powerful role in life on Earth When we think of electricity, we likely imagine the energy humming inside our home appliances or lighting up our electronic devices--or perhaps we envision the lightning-streaked clouds of a stormy sky. But electricity is more than an external source of power, heat, or illumination. Life at its essence is nothing if not electrical. The story of how we came to understand electricity's essential role in all life is rooted in our observations of its influences on the body--influences governed by the body's central nervous system. Spark explains the science of electricity from this fresh, biological perspective. Through vivid tales of scientists and individuals--from Benjamin Franklin to Elon Musk--Timothy Jorgensen shows how our views of electricity and the nervous system evolved in tandem, and how progress in one area enabled advancements in the other. He explains how these developments have allowed us to understand--and replicate--the ways electricity enables the body's essential functions of sight, hearing, touch, and movement itself. Throughout, Jorgensen examines our fascination with electricity and how it can help or harm us. He explores a broad range of topics and events, including the Nobel Prize-winning discoveries of the electron and neuron, the history of experimentation involving electricity's effects on the body, and recent breakthroughs in the use of electricity to treat disease. Filled with gripping adventures in scientific exploration, Spark offers an indispensable look at electricity, how it works, and how it animates our lives from within and without.

Henri Poincar矇 Electrons to Special Relativity
Produced by an award-winning translator of Henri Poincar矇, this book contains translations of several seminal articles by Poincar矇 and discusses the experimental and theoretical investigations of electrons that form their context. In the 1950s, a dispute ignited about the origin of the theory of special relativity and thrust considerable notoriety on a paper written by Henri Poincar矇 in 1905. Accordingly, Part I presents the relevant translations of Poincar矇's work showing that radiation carries momentum and the covariance of the equations of electrodynamics, the continuity equation for charge, and the spacetime interval. Part II then discusses investigations by Thomson, Becquerel, and Kaufmann of electrons in diverse contexts; contributions of Abraham, Lorentz and Poincar矇 to a theory of electrons that includes Lorentz transformations and explains the dependence of mass on velocity; and finally, Poincar矇's exploration of the relativity principle, electron stability, and gravitation while rejecting absolute motion (ether) and an electromagnetic origin of mass. Part III contains the 1904 article by H. A. Lorentz presenting his transformations.This book will be a fascinating read to graduate-level students, physicists, and science historians who are interested in the development of electrodynamics and the classical, relativistic theory of electrons at the beginning of the 20th century.

An Introduction to Quantitative Ecology
Environmental science (ecology, conservation, and resource management) is an increasingly quantitative field. A well-trained ecologist now needs to evaluate evidence generated from complex quantitative methods, and to apply these methods in their own research. Yet the existing books and academic coursework are not adequately serving most of the potential audience - instead they cater to the specialists who wish to focus on either mathematical or statistical aspects, and overwhelmingly appeal to those who already have confidence in their quantitative skills. At the same time, many texts lack an explicit emphasis on the epistemology of quantitative techniques. That is, how do we gain understanding about the real world from models that are so vastly simplified? This accessible textbook introduces quantitative ecology in a manner that aims to confront these limitations and thereby appeal to a far wider audience. It presents material in an informal, approachable, and encouraging manner that welcomes readers with any degree of confidence and prior training. It covers foundational topics in both mathematical and statistical ecology before describing how to implement these concepts to choose, use, and analyse models, providing guidance and worked examples in both spreadsheet format and R. The emphasis throughout is on the skilful interpretation of models to answer questions about the natural world. Introduction to Quantitative Ecology is suitable for advanced undergraduate students and incoming graduate students, seeking to strengthen their understanding of quantitative methods and to apply them successfully to real world ecology, conservation, and resource management scenarios.
Insights from Data with R
Experiments, surveys, measurements, and observations all generate data. These data can provide useful insights for solving problems, guiding decisions, and formulating strategy. Progressing from relatively unprocessed data to insight, and doing so efficiently, reliably, and confidently, does not come easily, and yet gaining insights from data is a fundamental skill for science as well as many other fields and often overlooked in most textbooks of statistics and data analysis. This accessible and engaging book provides readers with the knowledge, experience, and confidence to work with data and unlock essential information (insights) from data summaries and visualisations. Based on a proven and successful undergraduate course structure, it charts the journey from initial question, through data preparation, import, cleaning, tidying, checking, double-checking, manipulation, and final visualization. These basic skills are sufficient to gain useful insights from data without the need for any statistics; there is enough to learn about even before delving into that world! The book focuses on gaining insights from data via visualisations and summaries. The journey from raw data to insights is clearly illustrated by means of a comprehensive Workflow Demonstration in the book featuring data collected in a real-life study and applicable to many types of question, study, and data. Along the way, readers discover how to efficiently and intuitively use R, RStudio, and tidyverse software, learning from the detailed descriptions of each step in the instructional journey to progress from the raw data to creating elegant and informative visualisations that reveal answers to the initial questions posed. There are an additional three demonstrations online! Insights from Data with R is suitable for undergraduate students and their instructors in the life and environmental sciences seeking to harness the power of R, RStudio, and tidyverse software to master the valuable and prerequisite skills of working with and gaining insights from data.

Introduction to the Kinetics of Glow Discharges
Electric glow discharges (glows) can be found almost everywhere, from atmospheric electricity to modern plasma technologies, and have long been the object of research. Most books on this subject mainly describe the fundamental foundations on the basis of a fluid (hydrodynamic) approximation. In that approach the electron distribution function (EDF) depends on the local plasma parameters at a given point of space in a given time. However, under conditions of a gas-discharge plasma the EDF is usually strongly non-equilibrium and the fluid approximation cannot describe some important phenomena and processes. The appropriate approach for describing such highly non-equilibrium systems and phenomena is physical kinetics. Work in this area has progressed rapidly and a consistent kinetic description of the simplest glow discharges has become possible. This book provides simple illustrations of the basic physical mechanisms and principles that determine the properties of these categories of discharges so the reader can successfully participate in scientific and technical progress.
Infinite-Space Dyadic Green Functions in Electromagnetism
In any linear system the input and the output are connected by means of a linear operator. When the input can be notionally represented by a function that is null valued everywhere except at a specific location in spacetime, the corresponding output is an entity called the Green function in field theories. Dyadic Green functions are commonplace in electromagnetics, because both the input and the output are vector functions of space and time. Numerous research papers have been written on dyadic Green functions when both the input and the output are time harmonic and a linear homogeneous medium occupies all space. This book provides a self-contained survey of the state-of-the-art knowledge of infinite-space dyadic Green functions.
Theory of Electromagnetic Pulses
This short monograph presents the theory of electromagnetic pulses in a simple and physical way. All pulses discussed are exact solutions of the Maxwell equations, and have finite energy, momentum and angular momentum. There are five chapters: Fundamentals, Solutions of the wave equation, Electromagnetic pulses, Angular momentum, and Lorentz transformations. Nine appendices cover mathematical or associated aspects, such as chiral measures of electromagnetic fields. The subject matter is restricted to free-space classical electrodynamics, but contact is made with quantum theory in proofs that causal pulses are equivalent to superpositions of photons.
Light Science
What is the nature of light? How does an artist's selection and use of colorants determine how we experience a work of art? What can visual illusions tell us about the nature of perception? In what ways do the laws of optics manifest themselves in the visual arts? In this fully revised edition of the classic textbook, Rossing and Chiaverina present the science of light - that is, the science behind what and how we see. Their approach emphasizes phenomena rather than mathematical theories, and the joy of discovery rather than the drudgery of derivations - the opposite of "heavy science". The text explores such topics as: the effects of mirrors, lenses, and prisms on light and color; the physiology of the eye and the nature of color vision; the use and effect of color in the visual arts; the different kinds of sources of light; optical data storage technology; photography and holography; color in printing and painting; the applications of optics in astronomy, medicine, and communications; and computer imaging and processing. It includes numerous problems, questions for discussion, and suggestions for simple experiments to support interactive learning. This updated edition contains a wealth of new full-color artwork, and information on the latest developments in light source and display technologies. Requiring no prior knowledge of physics, it will appeal to students and any reader interested in the relationship between science and the visual arts.

Study of Induction Motor Fault Detection and Diagnosis
In this book, the authors evaluated the performance of the developed ANN based classifiers for detection of four fault conditions, Healthy (H), Interturn short circuit (I), Eccentricity (E). and Both i.e. Interturn and Eccentricity combine (B) of three phase induction motor and examined the results. Instead of current or vibration spectra simple statistical parameters containing fault information is used, which gives the satisfactory results. MLP NN, RBF NN, RBF-MLP Cascade, SOM NN, GFFD NN, and SVM are optimally designed and after completion of the training, the learned network is tested to detect different types of faults. Sensitivity Analysis and Principal Component Analysis (PCA), these two techniques for dimensionality reduction is applied for each network and reduction in complexity is compared. For the comparison two statistical methods CART and D.A. are verified but results are inferior as compared to NN based schemes. Robustness of proposed classifier to the noise is good which is checked by introducing controlled noise, and for training, cross validation and testing experimental real data is used, so this scheme can be suggested for the real world industrial application.

The Limits of Europeanisation. Domestic Constraints on Ownership Unbundling of National Electricity Systems
Master's Thesis from the year 2020 in the subject Politics - Topic: European Union, grade: 1,7, Maastricht University, language: English, abstract: While Bartle stresses that national institutions may protract the introduction of electricity reform, his research is on a more general level and does not explicitly focus on the costs of adaptation resulting from compensating losers of reform and convincing opposing political veto players. By doing so, important nuances of national responses to exogenous reform pressures may be overlooked. This thesis addresses this gap by asking the following research question: What explains the variation in unbundling regime choice between European countries after the Third Electricity Directive? The example of ownership unbundling provides a relevant empirical example to unequivocally comprehend the redistribution of resources resulting from a liberalisation reform initiative. When governments plan to unbundle VIUs, they directly interfere with the interests of several private and public actors. Thus, depending on the exact interest and governance configurations, full unbundling induces varying costs of compensation and (re-)negotiation for governments. I argue that an adaptation-cost-based account of member states' reform capacities allows us to obtain a better understanding of the pace and timing of electricity sector liberalisation in the EU as well as processes of Europeanisation more generally. The research question will be addressed through the lens of the rational-choice variant of B繹rzel & Risse's goodness-of-fit framework which is complemented by the historical institutionalist notion of path dependencies.

Spin Seebeck Effect
The Spin Seebeck Effect (SSE) was first reported in 2008 and consists in the generation of a spin current in a paramagnetic metal (PM), caused by an applied thermal gradient in a ferromagnet (FM). The injected spin current is converted into a transverse electric voltage by means of the Inverse Spin Hall Effect (ISHE), which is a result of a spin-orbit interaction of the electrons in the conductive layer. The SSE devices, due to their relatively simple structure, provide an easy scaling-capability, which attributes useful characteristics for thermoelectric and sensing applications to these devices. In this work, three different FM materials were prepared and characterized (YIG, La0.9Ca0.1MnO3 and NiO) and SSE devices were produced. An experimental set-up was designed and developed to measure the SSE output of these devices. Measurements were carried out at room temperature and up to 50簞C and an SSE output of up to 0.25 繕V was obtained.
Battery Management System for Microgrids
System has two operation modes, the unit-power control (UPC) mode and the feeder-flow control (FFC) mode, applied to hybrid system. When load is light, the UPC mode is selected. In UPC mode variation in load demands are compensated by the main grid because the hybrid source output is regulated to reference power. In FFC mode feeder flow is regulated to a constant power, the extra load demand is picked up by hybrid sources and hence feeder reference power must be known. The system can maximize the generated power when load is heavy and minimizes the load shedding area.The proposed operating strategies with flexible operation mode change always operates the photovoltaic array at maximum output power and battery in its high efficiency performance band, thus improving the performance of system operation, enhance system stability, decreasing the number of operating mode changes in the MATLAB Simulink environmen

Three Phase Induction Motor
Three phase induction motor is one of ac machines family. It converts the ac electrical power input into a mechanical power output. The conversion process takes place through the rotating magnetic field. Its theory of operation is based on the mutual electromagnetic induction between the primary circuit and secondary circuit. Three-phase induction motors are the most widely used electric motors in industry. When fed from constant voltage constant frequency they run at nearly constant speed from no-load to full-load. 3-phase induction motors are simple, rugged, low-priced, easy to maintain and can be manufactured with characteristics to suit most industrial requirements. Nowadays, with the development of power semiconductors, induction motors may be considered as serious rivals to dc motors in many speed control systems.
