Responding to the need for a clear, up-to-date introduction to the field, The Method of Moments in Electromagnetics explores surface integral equations in electromagnetics and presents their numerical solution using the method of moments (MOM) technique. It provides the numerical implementation aspects at a nuts-and-bolts level while discuss

Considerable progress has been made in the development of models to predict the response of wire ropes and to determine the effects of variations in the design on its performance. The book begins with the equations of equilibrium for a thin curved wire in space, before going on to solve these equations, and apply them to determine the stresses in a simple strand. These results are then extended to ropes with more complex cross sections. Numerous examples are worked out to illustrate the theory and the test results discussed. This second edition includes new chapters on tension and compression of a cord, fatigue, and approximations. Intended for graduate students and practising engineers, this makes for a comprehensive theoretical review of the subject.

Matter and Interactions offers a modern curriculum for introductory physics (calculus-based). It presents physics the way practicing physicists view their discipline and integrates 20th Century physics and computational physics. The text emphasizes the small number of fundamental principles that underlie the behavior of matter, and models that can explain and predict a wide variety of physical phenomena. Matter and Interactions will be available as a single volume hardcover text and also two paperback volumes.

As an introduction to the integral equation analysis of wire structures, this book and enclosed software packages contain the user friendly version of the boundary element software for modelling the straight thin wire arrays in both frequency and time domain.

Publisher Description

A clear and easy to follow textbook including material on forces, machines, motion, properties of matter, electronics and energy, problem-solving investigations and practice in experimental design.

This book focuses on the metallic Nano- and Micro-materials (NMMs) fabricated by physical techniques such as atomic diffusion. A new technology for fabricating NMMs by atomic diffusion is presented. Two kinds of atomic diffusion are treated; one is a phenomenon caused by electron flow in high density and called electromigration and the other is stress migration which depends on a gradient of hydrostatic stress in a material. In three parts, the book describes the theory of atomic diffusion, the evaluation of physical properties and the treatment and applications of metallic NNMS. The new methods such as atomic diffusion are expected are expected to be crucial for the fabrication of NNMs in the future and to partially replace methods based on chemical reactions.

This KS2 Science revision guide is for levels 3-5 inclusive and provides a concise summary of the work covered through Years 3-6 and covers all the skills which need to be demonstrated in Key Stage 2 assessments.

The TCP/IP technology has evolved over the years and undergone substantial improvements to meet the demands of modern high-speed network technologies. These demands involve the handling of increased traffic, providing better and efficient services, and implementing foolproof security measures for authentic and safe communication. Offering clear explanations of underlying issues, this book provides an accessible introduction the basic principles of the Internet and its accompany-ing TCP/IP protocol suit. It discusses a wide range of topics, including: • Principles and applications of TCP/IP and other relevant protocols • Coordination of multiple interconnected physical networks and protocols • Routing and its specific components—Internet addressing, protocol layering and implementation • Client-server model of communication • Internet security—issues and concepts This textbook is designed for students of BE/BTech pursuing courses in Computer Science and Engineering, Information Technology, as well as for students of computer applications (BCA and MCA). It can also be a valuable reference for ME/MTech students of Computer Science and Engineering and Information Technology, specializing in computer networks and network programming.

Updating and reorganizing the valuable information in the first edition to enhance logical development, Transformer Design Principles: With Applications to Core-Form Power Transformers, Second Edition remains focused on the basic physical concepts behind transformer design and operation. Starting with first principles, this book develops the reader’s understanding of the rationale behind design practices by illustrating how basic formulae and modeling procedures are derived and used. Simplifies presentation and emphasizes fundamentals, making it easy to apply presented results to your own designs The models, formulae, and methods illustrated in this book cover the crucial electrical, mechanical, and thermal aspects that must be satisfied in transformer design. The text also provides detailed mathematical techniques that enable users to implement these models on a computer. The authors take advantage of the increased availability of electromagnetic 2D and 3D finite element programs, using them to make calculations, especially in conjunction with the impedance boundary method for dealing with eddy current losses in high-permeability materials such as tank walls. Includes new or updated material on: Multi terminal transformers Phasors and three-phase connections Impulse generators and air core reactors Methodology for voltage breakdown in oil Zig-zag transformers Winding capacitances Impulse voltage distributions Temperature distributions in the windings and oil Fault type and fault current analyses Although the book’s focus is on power transformers, the transformer circuit models presented can be used in electrical circuits, including large power grids. In addition to the standard transformer types, the book explores multi-terminal transformer models, which allow complicated winding interconnections and are often used in phase shifting and rectifying applications. With its versatile coverage of transformers, this book can be used by practicing design and utility engineers, students, and anyone else who requires knowledge of design and operational characteristics.
