A Baby Sister for Frances
This is an introduction to the quantum theory of light and its broad implications and applications. A significant part of the book covers material with direct relevance to current basic and applied research, such as quantum fluctuations and their role in laser physics and the theory of forces between macroscopic bodies (Casimir effects). The book includes numerous historical sidelights throughout, and approximately seventy exercises. The book provides detailed expositions of the theory with emphasis on general physical principles. Foundational topics in classical and quantum electrodynamics are addressed in the first half of the book, including the semiclassical theory of atom-field interactions, the quantization of the electromagnetic field in dispersive and dissipative media, uncertainty relations, and spontaneous emission. The second half begins with a chapter on the Jaynes-Cummings model, dressed states, and some distinctly quantum-mechanical features of atom-field interactions, and includes discussion of entanglement, the no-cloning theorem, von Neumann's proof concerning hidden variable theories, Bell's theorem, and tests of Bell inequalities. The last two chapters focus on quantum fluctuations and fluctuation-dissipation relations, beginning with Brownian motion, the Fokker-Planck equation, and classical and quantum Langevin equations. Detailed calculations are presented for the laser linewidth, spontaneous emission noise, photon statistics of linear amplifiers and attenuators, and other phenomena. Van der Waals interactions, Casimir forces, the Lifshitz theory of molecular forces between macroscopic media, and the many-body theory of such forces based on dyadic Green functions are analyzed from the perspective of Langevin noise, vacuum field fluctuations, and zero-point energy.

Microgrid Design for Ev Fast Charging Station
The utilization of range of electric vehicles is increases rapidly and still in some areas it is limited due to more charging times. This can be improved by providing fast charging conditions that enable to charge a vehicle in less time. To maintain this fast charging conditions an efficient, compact size dc-dc converter with high power output is required. This paper proposes an interleaved dc-dc power converter to meet the above requirements. The proposed interleaved multi-phase converter, which is part of fast charging stations, has capable to charge the electric vehicle in less than 3hours time. To achieve high power density, ripple reduction on the output current and to improve the efficiency of converter a space vector modulation technique is applied. The operation of interleaved converter is analyzed in theoretically. Simulation analysis of proposed interleaved power converter shows the good behavior of converter, and charging conditions of various electric vehicle systems.
The Sentient Cell
All species, extant and extinct, from the simplest unicellular prokaryotes to humans, have an existential consciousness. Without sentience, the first cells that emerged some 4 billion years ago would have been evolutionary dead-ends, unable to survive in the chaotic, dangerous environment in which life first appeared and evolved. In this book, Arthur Reber's theory, the Cellular Basis of Consciousness (CBC), is outlined and distinguished from those models that argue that minds could be instantiated on artificial entities and those that maintain consciousness requires a nervous system. The CBC framework takes a novel approach to classic topics such as the origin-of-life, philosophy of mind, the role of genes, the impact of cognition, and how biological information is processed by all species. It also calls for a rethinking of a variety of issues including the moral implications of the sentient capacities of all species, how welfare concerns need to be expanded beyond where they currently are, and critically, how all life is intertwined in a coordinated cognitive ecology. The Sentient Cell explores this revolutionary model, which updates the standard neo-Darwinian framework within which current approaches operate and examines the underlying biomolecular features that are the likely candidates for the "invention" of consciousness and outline their role in cellular life.
Classical and Quantum Parametric Phenomena

Optics II
The light can be considered as the physical agent essential to the vision. It is an electromagnetic wave with a double aspect: It is an electromagnetic field that varies in space and time, the light is therefore part of electromagnetic waves. This is its wave aspect. It is also a flow of particles or photons which gives light the corpuscular aspect. Unlike the geometric optics treated in optics I, optics II describes the phenomena of interference and diffraction that occur when the sources are coherent with each other: . The phenomenon of light polarization is the process of converting unpolarized light into polarized light. The light in which the particles vibrate in a direction or in a preferred geometric form is called polarized light. The Fresnel coefficients, express the relationship between the amplitudes of reflected and transmitted waves in relation to the amplitude of the incident wave. They evaluate the optical behavior of optical multilayers, from the simplest of them, the blade with parallel face, to the most complex.
The Story Of Electricity
John Munro wrote the tale of electricity. Readers of biographical novels are presented with a fictional account of a real-life or historical figure. Such biographies add fictional details or enhance the genuine lives of historical or contemporary figures. Romantic relationships between two or more people are the main subject of books in the romance novel genre. Other genres, like fantasy or historical romance, may also have characteristics present in this one. Northanger Abbey, Two on a Tower, Flatland, The Boundary of Blades: an Anglo-Indian romance, A Rose of a Hundred Leaves, An experiment in marriage, and Betty: A Last Century Love Story are a few titles that fall under this category. This small book's goal is to convey the fundamentals of electrical science in a clear and engaging manner, in keeping with the overall design of the series to which it belongs. The first man witnessed one of the most stunning and magnificent electrical phenomena, the thunderstorm, but the electrical utilities we now take for granted are exclusively the result of scientific advancement in the nineteenth century. The majority of the discussion that follows is devoted to these services.

Are Electromagnetic Fields Making Me Ill?
Electricity and Magnetism (E&M) underlies many lifesaving medical devices, such as magnetic resonance imaging scanners, neural stimulators, and heart pacemakers. But E&M also attracts its share of bogus health claims, such as biomagnetic therapy. How do you separate the good from the bad? Sometimes it's not easy: experiments are prone to artifacts, theories are limited by assumptions, and clinical trials can result in ambiguities. In this book, the author separates the wheat from the chaff, showing which applications of E&M are bogus and which are not. This book takes the reader on a tour through a range of fascinating phenomena, from effects that are constant in time at one extreme, such as transcranial direct current stimulation of the brain, to the millimeter-wave whole-body scanners which are familiar to frequent flyers at the other. Along the way, the author looks in depth at the dispute about power line magnetic fields and leukemia, a case study in what can go wrong when dubious claims inflame unjustified fears. The debate about cell phones and brain cancer still rages today, particularly for the microwave frequencies encountered with new 5G technology. Recently, the so-called Havana Syndrome has been attributed to microwave weapons, but the underlying biophysics of such weapons is unclear. For all these encounters with electricity and magnetism, the author, an eminent biophysicist, uses science and evidence to sort out fact from fantasy. This book is aimed at general readers who want to make sense of the mysterious and often controversial ways in which E&M interacts with the human body. It is also ideal for students and professionals in bioscience and health-related fields who want to learn more without getting overwhelmed by theory.

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.

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.
Novel Magnetic Properties in Curved Geometries
This reprint focuses on fundamentals and applied research on magnetic structures with curved geometries. The influence of curvature in the magnetic structures is an appealing topic of research opening novel perspectives to engineer the magnetic textures and the magnetisation reversal processes. Special attention is given to the fabrication and optimisation of magnetic structures, their characterisation and possible use in technological applications.
Electromagnetism
Any curriculum involving science and/or engineering will eventually find itself entering the realm of physics. This book seeks to introduce students to a number of the fundamental concepts in physics and illustrate how different theories were developed out of physical observations and phenomena. The book presents multi-chapter sections on electrostatics, magnetism and electromagnetic waves, with eyes on both the past and the future, touching, along the way, on Coulomb, Gauss, Maxwell, Ohm, Biot-Savart, Ampere, Faraday, Fresnel and Lorentz. The book also contains an appendix that provides the reader with a portion of the mathematical background of vector analysis and vector differential operators. The book approaches its topics through a focus on examples and problem-solving techniques, illustrating vividly how physical theories are applied to problems in engineering and science. The book is primarily aimed at undergraduate students in these two fields, but it also featureschapters that are geared towards senior undergraduates working on their final year theses.
