Basic Processes of Gaseous Electronics
Basic Processes of Gaseous Electronics is an advanced exploration into the field of gaseous electronics, building upon the foundational work presented in the author's earlier book, Fundamental Processes of Electrical Discharge in Gases (1939). The earlier book provided a comprehensive review of the subject, addressing gaps in knowledge and methodology that had emerged over decades of research. The current volume acknowledges the transformative advances in technology, theory, and experimental methods made over the intervening fifteen years, including innovations in microwave techniques, short-duration pulsed potentials, and high-speed oscilloscopes. These developments have enabled deeper insights into phenomena such as electron-energy distributions, ionization, recombination, and the mechanisms underlying electrical discharge. This book incorporates significant theoretical and experimental progress, including refinements in the kinetic theory of nonequilibrium gases and analyses of electron and ion behavior. Contributions from leading researchers and collaborative efforts within the scientific community have shaped its content, offering updated, critically evaluated data tables and new insights into processes like ionic drift, electron attachment, and the Townsend coefficients. While maintaining the logical structure of the earlier work, this volume introduces new topics, reorganizes chapters for clarity, and presents previously unpublished or cutting-edge findings. The book serves as both a foundational text for students and a reference for professionals, emphasizing simplified physical principles to aid comprehension of complex phenomena. Through this effort, the author seeks to advance the understanding of gaseous electronics and lay the groundwork for future studies and specialized works in the field.

Statistical methods have a long history in the analysis of hydrological data for de-signing, planning, infilling, forecasting, and specifying better models to assess scenarios of land use and climate change in catchments. The effectiveness of statistical descriptions of hydrological processes reflects the enormous complexity of hydrological systems, which makes a purely deterministic description ineffective. This book hosts 11 papers devoted to statistics in hydrology, summarizing the recent advancement in statistical methods for hydrological studies such as statistical analysis of changes in hydrometeorological variables, forecasting and prediction of hydrological elements, hydrological forecasting uncertainty analysis, the use of new statistical methodologies for engineering hydrological design under stationary/nonstationary conditions, and so on. In general, the book will contribute to the promotion of the application of statistical methods in hydrology.
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

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.

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.
Electronic Instrumentation for AC Susceptibility Measurement
In recent days the state of art technology is the development of an instrumentation, for industrials, agricultural and R & D etc sectors. Recently, it is found that, the characterization of materials plays vital role in the field of material science. For materials research the different properties of the materials are explored, to investigate the structural details of materials under investigation. The properties to be determined depend upon the material and their application potential. Investigations of various properties, particularly of magnetic materials are of great interest. It is found that, the magnetic material reflects their characteristics through magnetic parameters such as Saturation Magnetization (Ms), Magnetic Moment (ηβ), Initial Permeability (μ), AC susceptibility (χ), Corecivity (Hc), and Retaintivity (Mr) etc. Therefore, in order to investigate the magnetic properties one should use sophisticated instrumentation. Microcontroller based embedded system is found to be most reliable. Therefore, Smart embedded system design issues for measurement of AC Susceptibility of Magnetic Material using high performance Microcontroller presented in this book.
Time Based Development Planning of Distribution Networks
In the book, a time-based model for distribution network development planning is presented, considering the possibility of using distributed energy generation technologies and the existence of capacitor banks. The proposed model specifies the appropriate location, capacity, and time for the use of distributed generation technologies and capacitor banks, as well as the schedule for increasing the capacity of network lines. To solve the problem, a genetically enhanced algorithm is used to optimize the network development plan, including the time, place, and capacity of DG and capacitor banks in the distribution network, as well as to optimize investment costs and operating costs. Also, in order to validate and evaluate the efficiency of the proposed solution to solve the distribution network development planning problem on a 17-bus radial distribution network, it was implemented in the MATLAB programming environment in a computer system.

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.

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 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. This book provides a survey of the state-of-the-art knowledge of infinite-space dyadic Green functions.

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.
