Technology-Based Entrepreneurship

This textbook begins by introducing the area of technology-based entrepreneurship (TBE), taking into account definitions and background of the subject area, and sets this into context through TBE Education and Regional Development. This is followed by considering technology transfer policy, the diffusion of innovation into technology-based firms (TBFs), technology clusters, university technology small firms (UTSFs), university business collaborations and partnerships, and the growth of a technology concept. This exciting new approach to technology-based entrepreneurship will be of interest not only to students, researchers and scholars of entrepreneurship but also to policy makers, small business practitioners and owner managers. In this way it is hoped that this textbook will provide a greater understanding of technology-based entrepreneurship in the emerging knowledge economy.

Introduction to Queueing Theory and Stochastic Teletraffic Models

The aim of this textbook is to provide students with basic knowledge of stochastic models with a special focus on queueing models that may apply to telecommunications topics, such as traffic, performance evaluation, resource provisioning, and traffic management. These topics are included in a field called teletraffic. This book assumes prior knowledge of a programming language and mathematics normally taught in an electrical engineering bachelor program. The book aims to enhance intuitive and physical understanding of the theoretical concepts it introduces. The famous mathematician Pierre-Simon Laplace is quoted to say that “Probability is common sense reduced to calculation” as the content of this book falls under the field of applied probability, Laplace’s quote very much applies. Accordingly, the book aims to link intuition and common sense to the mathematical models and techniques it uses. It mainly focuses on steady-state analyses and avoids discussions of time-dependent analyzes.

While you can find much of this information dispersed among datasheets, introductory books, websites, and technical resources maintained by manufacturers, the Encyclopedia of Electronic Components gathers all the relevant facts in one place, properly organized and verified, including details that may be hard to find elsewhere. Each entry includes typical applications, possible substitutions, cross-references to similar devices, sample schematics, and a list of common problems and errors

CWNA Certified Wireless Network Administrator Official Study Guide

The wireless networking market is in a continual state of change. There have been more than a dozen amendments to the IEEE 802.11 standard since it was first released, and as I write these words in mid-2007, the IEEE is preparing to release the IEEE 802.11-2007 rollup any day now. For this reason, it is important that a wireless network administrator stay on top of the changes in wireless networking. This book and the CWNA certification is a great place to start

The Essential Guide to Telecommunications

When The Essential Guide to Telecommunications was first published in 1997, broadband and cellular networks were many times less complex. Voice calls were carried separately from data traffic, and e-mail required arcane commands and was used mostly at universities. The federal government had recently deregulated telecommunications and opened it to competitors. Deregulation opened voice and data networks to new competitors. These competitors competed with established providers for subscribers by offering lower prices. This competition drove innovation and resulted in the build-out of high-speed fiber-optic networks. Large incumbents responded with their own network improvements and lowered prices.

Telecommunications Engineering

Telecommunication engineering is concerned with the transmission of information between two distant points. Intuitively we may say that a signal contains information if it tells us something we did not already know. This definition is too imprecise for telecommunications studies, and we shall devote a section of this chapter to a formal description of information. For the present it is sufficient to say that a signal that contains information varies in an unpredictable or random manner. We have thus specified a primary characteristic of the signals in telecommunications systems; they are random in nature.

Wireless Receiver Design for Digital Communications

There are entire books that deal with statistics, logarithms, significant figures, transmission lines, and s-parameters. We are interested in understanding and designing radio receivers and systems, which requires at least a passing knowledge of all these topics and more. This chapter serves as an introduction to many of the basic concepts we will need in later chapters. This is an optional chapter. Many readers will find the information presented here very basic and may choose to pass this chapter over. For others, it will be required reading. Some of the purists out there may argue that the information presented here is imprecise, incomplete, and greatly simplified. Again, the purpose of this chapter is to acquaint the reader with some of the fundamental material we’ll need later on. For a more complete treatment of any of the topics listed here, refer to the bibliography at the end of the chapter.

Signal Integrity Issues and Printed Circuit Board Design

There are a great many people who have contributed to this book in some way or another. Pete Waddell and his team have been great to work with through the years on both the article and the seminar levels. I have been very grateful to have met and come to know many of the leaders in our field—wonderful colleagues who learn from each other and who have a lot of fun together. People like Glenn Wells and Gary Farrari have been inspirations as I have watched how much they have given back to the development and growth of new designers starting out in our field. Glenn, in particular, seems to be everywhere in our industry—classroom, seminar room, college administrator’s office pounding the desk for more funds for program development, Top Gun contestant, and Top Gun program coordination. I am honored to count him as a friend and I appreciate the help he has given me with this book during the various phases of its development.

A Student’s Guide to Maxwell’s Equations

Gauss's law for electric fields, Gauss's law for magnetic fields, Faraday's law, and the Ampere-Maxwell law are four of the most influential equations in science. In this guide for students, each equation is the subject of an entire chapter, with detailed, plain-language explanations of the physical meaning of each symbol in the equation, for both the integral and differential forms. The final chapter shows how Maxwell's equations may be combined to produce the wave equation, the basis for the electromagnetic theory of light. This book is a wonderful resource for undergraduate and graduate courses in electromagnetism and electromagnetics.

Classical Electromagnetism

This text advances from the basic laws of electricity and magnetism to classical electromagnetism in a quantum world. Suitable for first-year graduate students in physics who have taken an undergraduate course in electromagnetism, it focuses on core concepts and related aspects of math and physics. Progressing from the basic laws of electricity and magnetism and their unification by Maxwell and Einstein, the treatment culminates in a survey of the role of classical electromagnetism in a quantum world. Each stage of the theory is carefully developed in a clear and systematic approach that integrates mathematics and physics so that readers are introduced to the theory and learn the mathematical skills in context of real physics applications. Topics include methods of solution in electrostatics, Green's functions, electrostatics in matter, magnetism and ferromagnetism, electromagnetic waves in matter, special relativity, and the electrodynamics of moving bodies. Newly revised by author Jerrold Franklin, the book includes the new section Answers to Odd-Numbered Problems.

Basic laws of electromagnetism

The main idea behind this book is to amalgamate the description of the basic concepts of the theory and the practical methods of solving problems in one book. Therefore, each chapter contains first a description of the theory of the subject being considered (illustrated by concrete examples) and then a set of selected problems with solutions. The problems are closely related to the text and often complement it. Hence they should be analysed together with the text. In author’s opinion, the selected problems should enable the reader to attain a deeper understanding of many important topics and to'visualize (even without solving the problems but just by going through them) the wide range of applications of the ideas presented in this book.
