Signals and Systems: A Primer with MATLAB (R) provides clear,
interesting, and easy-to-understand coverage of continuous-time and
discrete-time signals and systems. Each chapter opens with a
historical profile or career talk, followed by an introduction that
states the chapter objectives and links the chapter to the previous
ones. All principles are presented in a lucid, logical,
step-by-step approach. As much as possible, the authors avoid
wordiness and detail overload that could hide concepts and impede
understanding. In recognition of the requirements by the
Accreditation Board for Engineering and Technology (ABET) on
integrating computer tools, the use of MATLAB (R) is encouraged in
a student-friendly manner. MATLAB is introduced in Appendix B and
applied gradually throughout the book. Each illustrative example is
immediately followed by a practice problem along with its answer.
Students can follow the example step by step to solve the practice
problem without flipping pages or looking at the end of the book
for answers. These practice problems test students' comprehension
and reinforce key concepts before moving on to the next section.
Toward the end of each chapter, the authors discuss some
application aspects of the concepts covered in the chapter. The
material covered in the chapter is applied to at least one or two
practical problems or devices. This helps students see how the
concepts are applied to real-life situations. In addition,
thoroughly worked examples are given liberally at the end of every
section. These examples give students a solid grasp of the
solutions as well as the confidence to solve similar problems
themselves. Some of the problems are solved in two or three ways to
facilitate a deeper understanding and comparison of different
approaches. Ten review questions in the form of multiple-choice
objective items are provided at the end of each chapter with
answers. The review questions are intended to cover the "little
tricks" that the examples and end-of-chapter problems may not
cover. They serve as a self-test device and help students determine
chapter mastery. Each chapter also ends with a summary of key
points and formulas. Designed for a three-hour semester course on
signals and systems, Signals and Systems: A Primer with MATLAB (R)
is intended as a textbook for junior-level undergraduate students
in electrical and computer engineering. The prerequisites for a
course based on this book are knowledge of standard mathematics
(including calculus and differential equations) and electric
circuit analysis.

An electric machine is a device that converts mechanical energy
into electrical energy or vice versa. It can take the form of an
electric generator, electric motor, or transformer. Electric
generators produce virtually all electric power we use all over the
world. Electric machine blends the three major areas of electrical
engineering: power, control and power electronics. This book
presents the relation of power quantities for the machine as the
current, voltage power flow, power losses, and efficiency. This
book will provide a good understanding of the behavior and its
drive, beginning with the study of salient features of electrical
dc and ac machines.
The author of this book has identified the seven key emerging
Internet-related technologies: Internet of things, smart
everything, big data, cloud computing, cybersecurity,
software-defined networking, and online education. Together these
technologies are transformational and disruptive. This book
provides researchers, students, and professionals a comprehensive
introduction, applications, benefits, and challenges for each
technology. It presents the impact of these cutting-edge
technologies on our global economy and its future. The word

Until now, novices had to painstakingly dig through the literature
to discover how to use Monte Carlo techniques for solving
electromagnetic problems. Written by one of the foremost
researchers in the field, Monte Carlo Methods for Electromagnetics
provides a solid understanding of these methods and their
applications in electromagnetic computation. Including much of his
own work, the author brings together essential information from
several different publications. Using a simple, clear writing
style, the author begins with a historical background and review of
electromagnetic theory. After addressing probability and
statistics, he introduces the finite difference method as well as
the fixed and floating random walk Monte Carlo methods. The text
then applies the Exodus method to Laplace's and Poisson's equations
and presents Monte Carlo techniques for handing Neumann problems.
It also deals with whole field computation using the Markov chain,
applies Monte Carlo methods to time-varying diffusion problems, and
explores wave scattering due to random rough surfaces. The final
chapter covers multidimensional integration. Although numerical
techniques have become the standard tools for solving practical,
complex electromagnetic problems, there is no book currently
available that focuses exclusively on Monte Carlo techniques for
electromagnetics. Alleviating this problem, this book describes
Monte Carlo methods as they are used in the field of
electromagnetics.
Broadband networks, such as asynchronous transfer mode (ATM), frame
relay, and leased lines, allow us to easily access multimedia
services (data, voice, and video) in one package. Exploring why
broadband networks are important in modern-day telecommunications,
Introduction to Broadband Communication Systems covers the concepts
and components of both standard and emerging broadband
communication network systems. After introducing the fundamental
concepts of broadband communication systems, the book discusses
Internet-based networks, such as intranets and extranets. It then
addresses the networking technologies of X.25 and frame relay,
fiber channels, a synchronous optical network (SONET), a virtual
private network (VPN), an integrated service digital network
(ISDN), broadband ISDN (B-ISDN), and ATM. The authors also cover
access networks, including digital subscriber lines (DSL), cable
modems, and passive optical networks, as well as explore wireless
networks, such as wireless data services, personal communications
services (PCS), and satellite communications. The book concludes
with chapters on network management, network security, and network
testing, fault tolerance, and analysis. With up-to-date, detailed
information on the state-of-the-art technology in broadband
communication systems, this resource illustrates how some networks
have the potential of eventually replacing traditional dial-up
Internet. Requiring only a general knowledge of communication
systems theory, the text is suitable for a one- or two-semester
course for advanced undergraduate and beginning graduate students
in engineering, as well as for short seminars on broadband
communication systems.
A fast-growing area in the communications industry is the
internetworking of an ever-increasing proliferation of computers,
particularly via local area networks (LANs). The LAN is a
resource-sharing data communications network being used by many
offices to interchange information such as electronic mail, word
processing, and files among computers and other devices. This
unique book shows the user how to establish the performance
characteristics of a LAN before putting it to use in a particular
type of situation. Simulation of Local Area Networks consists of
eight chapters, each with its own extensive list of references. The
first chapter provides a brief review of local area networks, and
the second chapter gives the analytical models of popular
LANs-token-passing bus and ring networks, CSMA/CD LANs, and star
networks. Chapter 3 covers general principles of simulation, and
Chapter 4 discusses fundamental concepts in probability and
statistics relating to simulation modeling. Materials in Chapters 3
and 4 are specifically applied in developing simulation models on
token-passing LANs, CSMA/CD LANs, and star LANs in Chapters 5
through 7. The computer code in Chapters 5, 6, and 7 is divided
into segments, and a detailed explanation of each segment is
provided. The last chapter reviews special-purpose languages such
as GPSS, SIMSCRIPT, GASP, SIMULA, SLAM, and RESQ. Helpful criteria
for language selection are included. The entire code is put
together in the appendixes. This book has two major advantages over
existing texts. First, it uses C, a well-developed general-purpose
language that is familiar to most analysts. Second, the text
specifically applies the simulation principles to local area
networks. No other book available shows the systems analyst how to
evaluate the performance of existing or proposed systems under
different kinds of conditions.
Analytical Techniques in Electromagnetics is designed for
researchers, scientists, and engineers seeking analytical solutions
to electromagnetic (EM) problems. The techniques presented provide
exact solutions that can be used to validate the accuracy of
approximate solutions, offer better insight into actual physical
processes, and can be utilized in finding precise quantities of
interest over a wide range of parameter values. Beginning with a
review of basic EMs, the text: Describes the use of the separation
of variables technique in Laplace, heat, and wave equations,
covering rectangular, cylindrical, and spherical coordinate systems
Explains the series expansion method, providing the solution of
Poisson's equation in a cube and in a cylinder, and scattering by
cylinders and spheres, as examples Addresses the conformal
transformation technique, offering a visual display of conformal
mapping and a brief introduction to the Schwarz-Christoffel
transformation Employs worked-out problems to demonstrate various
applications of Fourier sine and cosine, two-sided Fourier,
Laplace, Hankel, and Mellin transform techniques Discusses
perturbation techniques, supplying examples of perturbed results
degenerating to their unperturbed versions as the perturbation
parameters tend to zero Analytical Techniques in Electromagnetics
maintains a balanced view of techniques for solving EM problems,
refusing to overemphasize the importance of analytical methods at
the expense of numerical techniques. Carefully selected topics give
readers an appreciation of the kinds of EM problems that can be
solved exactly.
