Electromagnetic Measurement, Positioning and Hyperthermia
This article aims to show the reader new technologies in cancer treatment, which are gradually becoming a reality. Magnetic hyperthermia consists of applying magnetic fields to tumours in an attempt to provoke apoptotic cell renewal, a less painful and more natural way of treating cancer. To focus the electromagnetic fields on a tumour and promote heating from the inside out, the author analyses different types of biocompatible implants to be inserted into the tumour site to serve as targets. From sutures currently used in surgical procedures to metallic nanoparticles, the author analyses the possibility of using different biocompatible materials in this technique. In addition, the author also suggests the electromagnetic instrumentation required for heating, commenting on the possibility of using aerospace technology to promote greater efficiency in the process. This work served as the Final Work for the Degree in Electrical Engineering, earning the author the title of Electrical Engineer.
Estudo do Coeficiente de Acoplamento de um Acoplador Triplo Triangular
This work presents an analysis of the coupling coefficient (C), observing the behavior of the fiber with three waveguides with a triangular arrangement, based on Photonic Crystal Fiber (PCF). The numerical study was based on solving the pair of equations for coupled modes using the Runge-Kutta numerical method. Initially, the propagation properties of ultrashort pulses with a temporal width of 100 femtoseconds (fs) of light in the form of fundamental solitons were investigated. Studies are also carried out measuring the critical power, observing the power variation during transmission and thus discovering the critical points.
Electric Energy Meters
This book work makes reference in the first chapter, about the first electric company in Ecuador, how it originated and what they used to generate energy at that time.

Finally, it explains the work that was done for the sustentation of this book.
Solar Installation
Electrical energy is becoming increasingly essential to modern life, especially in terms of development and comfort. Capturing the sun's rays and transforming them into electric current is now possible and easy, thanks to technological expansion in the field of solar voltaic panel manufacture. But then the great difficulty lies in storing the electrical energy produced. Storing electricity as efficiently as we can store water or petrol is impossible at present (solar PV or other energy sources). In solar systems, inter-seasonal storage is virtually impossible to implement. With a solar pump that runs on the sun, we can store water rather than electricity. New forms of storage may borrow from the properties of lithium-based intercalation chemistry.

ABB company relays and how they are used and function in circuits
Currently, the use of distributed intelligence with microprocessors that communicate through optical fibers and the use of personal computers as human-machine interfaces is common. Therefore, new developments are constantly being made in this area, and as a result, costs are reduced and performance is improved. In addition, more trained personnel are familiar with this new technology. The heavily centralized, top-down systems used in the 1960s and 1970s are no longer appropriate, as decentralized systems can more easily adapt to future changes than centralized systems. In addition, different generations of equipment made by different manufacturers can be easily combined in them. Updating or expanding such a distributed system is simple. For example, in the following, a comparison between a common electric high pressure post and a fully automatic high pressure post using digital technology has been made.
Eco-Fan
Eco-fan is an electric motor of 220 (VAC), 50 (Hz), PMSM type (with ferrite magnet rotor). According to the IRAM 62480:2017 Standard, an Energy Efficiency (EE) Type: A. With an energy consumption lower than 55% of the nominal value of the motor. Value calculated for one (1) hour per day at maximum power: 25 (Watts). 59% active electrical energy saving. The physical unit of physical measurement (MKS) shows an energy consumption of 15 kWh/month (kiloWatt-hours/month), at maximum speed, without losing or lowering revolutions per minute (close to 3000 RPM), which is the synchronous speed of the two (2) pole rotor with the frequency of the alternating current (50 Hertz). PMSM type motors (like the one used here) provide rotation at a fixed speed in synchronicity with the frequency of the power supply, regardless of the load fluctuation (higher or lower) that produces the resistant torque. The voltage (Volts) and current (Amps) of the current drops when the TRIAC acts; and anyway, the motor runs at a synchronous speed (3000 RPM) with mains frequency (50 Hz).
ArcGIS and ADMS, for control of Electrical Distribution Systems
The electricity distribution system with increasing energy demand needs to incorporate an automatic control and visualisation system, tools for decision making and problem solving, such as electrical faults in the network. This is achieved with the Arcgis platform that helps in asset statistics and in the planning or dimensioning of new feeders of the electrical network and as a base or support for automatic and monitoring systems such as the ADMS system, for which the present work studies its integration with Arcgis. The input of information of a three-phase radial feeder is shown, with the respective attributes of each element, obtaining real information from the site that was digitised, obtaining statistical data such as km of line, number of transformers, number of users, number of disconnectors, number of luminaires, with the purpose of simulating with real data. Additionally, the integration between Arcgis and ADMS and its different work modules that allow the management of actuators and sensors in real time is studied.

Electromagnetic Radiation
Electromagnetic Radiation is a graduate level book on classical electrodynamics with a strong emphasis on radiation. This book is meant to quickly and efficiently introduce students to the electromagnetic radiation science essential to a practicing physicist. While a major focus is on light and its interactions, topics in radio frequency radiation, x-rays, and beyond are also treated. Special emphasis is placed on applications, with many exercises and problems. The format of the book is designed to convey the basic concepts in a mathematically rigorous manner, but with detailed derivations routinely relegated to the accompanying side notes or end of chapter "Discussions". The book is composed of four parts: Part I is a review of basic E&M (electricity and magnetism), and presents a concise review of topics covered in the subject. Part II addresses the origins of radiation in terms of time variations of charge and current densities within the source, and presents Jefimenko's field equations as derived from retarded potentials. Part III introduces special relativity and its deep connection to Maxwell's equations, together with an introduction to relativistic field theory, as well as the relativistic treatment of radiation from an arbitrarily accelerating charge. A highlight of this part is a chapter on the still partially unresolved problem of radiation reaction on an accelerating charge. Part IV treats the practical problems of electromagnetic radiation interacting with matter, with chapters on energy transport, scattering, diffraction and finally an illuminating, application-oriented treatment of fields in confined environments.

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 Dynamics of a Charged Sphere
"This is a remarkable book. [...] A fresh and novel approach to old problems and to their solution." -Fritz Rohrlich, Emeritus Professor of Physics, Syracuse University This reexamination of the classical model of the electron, introduced by H. A. Lorentz more than 100 years ago, serves as both a review of the subject and as a context for presenting new material. The new material includes the determination and elimination of the noncausal behavior in the original equation of motion, and the derivation of the binding forces and total stress-momentum-energy tensor for a charged insulator moving with arbitrary velocity. The final equations of motion are given in a number of different formats to allow them to be readily used by physicists, engineers, and mathematicians.
A Modern Introduction to Classical Electrodynamics
A Modern Introduction to Classical Electrodynamics is suitable for undergraduate students with some background knowledge of the subject and for graduate students, while more advanced topics make it a useful resource for PhD students and researchers. The book places much emphasis on the formal structure of the theory; beginning with Maxwell's equations in the vacuum, it emphasises the central role of gauge invariance and Special Relativity. After introductory chapters which include rederivations of elementary results of electrostatics and magnetostatics, and the multipole expansion, Special Relativity is introduced, and most of the subsequent derivations are performed using covariant formalism and gauge potentials, allowing for greater conceptual and technical clarity compared to more traditional treatments. The second part of the book covers electrodynamics in material media. This includes Maxwell's equations in material media, frequency dependent response of materials and Kramers-Kronig relations, electromagnetic waves in materials, and scattering of electromagnetic radiation. Finally, the text also includes advanced topics, such as the field-theoretical treatment of classical electrodynamics as a modern treatment of radiation reaction. These parts are meant for the advanced reader and are clearly marked, and can be skipped without loss of continuity.

High-Energy Waveform Synthesis for Physics
The motivation to control and temporarily isolate a single quantum mechanical event like an electronic transition has driven the quest for ever shorter light pulses. Controlling a highly intense electric field in the visible to infrared wavelength range on a sub-cycle time scale becomes feasible with the concept of the parametric waveform synthesizer. High harmonic generation(HHG) is explored as a primary application with the aim to generate isolated attosecond pulses and high photon energies in the "Water Window" spectral region from 284 eV to 533 eV. The tight synchronization of pulses from optical parametric amplifiers (OPAs) spanning from 650 nm to 2200 nm is achieved with long-term synthesized waveform stability. To work out and monitor the ideal synthesis parameters, a set of characterization methods are developed in the time and spatial domain.

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.
Pid Tuning

To alleviate the usual difficulties, plain H∞ weighted sensitivity problem has been used.
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.

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
Classical and Quantum Parametric Phenomena provides an overview of the phenomena arising when parametric pumping is applied to oscillators. These phenomena include parametric amplification, noise squeezing, spontaneous symmetry breaking, activated switching, cat states, and synthetic Ising spin lattices. To understand these effects, topics such as nonlinear and stochastic dynamics, coupled systems, and quantum mechanics are introduced. Throughout the book, introductions are kept as succinct as possible and attention is focused on understanding parametric oscillators. As a result, the text helps readers to familiarize themselves with many aspects of parametric systems and understand the common theoretical origin of nanomechanical sensors, optical amplifiers, and superconducting qubits. Parametric phenomena have enabled important scientific breakthroughs over the last decades and are still at the focus of intense research efforts. This book provides a resource for experimental and theoretical physicists entering the field or wishing to gain a deeper understanding of the underlying connections. This includes combining formal and intuitive explanations, accompanied by exercises based on numerical Python codes. This combination allows readers to experience parametric phenomena from various directions and apply their understanding directly to their own projects.

Reliability Analysis of Power Distribution System
Reliability of power systems has been occupying an important measure of system performance and a key factor in system planning, design, and maintenance. The power regime can be divided into three major areas of operation namely, generation, transmission, and distribution. The main duty of distribution system is to deliver an uninterrupted electricity to consumers in changing conditions within accepted levels of cost and reliability. However, it has been found that more than 80% of failures occur in the distribution area. Recently, therefore, many utilities have been concentrating on evaluating and improving their distribution system reliability. This book titled "Reliability Analysis of Power Distribution System" is the first edition and written by Mohammed Wadi. It covers all the fundamentals of probability and statistics required to perform all the reliability analysis and modeling. Besides, it covers the most interruption causes in power distribution, reliability assessments of simple power systems, reliability assessments of complex power systems, reliability assessments of closed-ring power systems, historical reliability assessments.
