This book is intended for one or two courses on basic electric circuits as well as the “Circuits and Signals” course, CE-CSG, described in the Body of Knowledge of the IEEE/ACM. It differs from other textbooks in its coverage, organization, and presentation, which strongly emphasize fundamentals and stresses creative problem solving. By emphasis on funda- mentals I mean: (1) being comprehen…
Traditional security mechanisms restrict access to authorized users only, in order to protect resources from malicious users. However, in many con- texts, we must protect ourselves from those who offer resources, so that the problem is in fact reversed. This improper usage cannot be addressed by traditional security mechanisms, and the issues relate more to trustworthiness than security. Trus…
This strikes me as a particularly apt description of how science proceeds on a day-to-day basis. It is certainly more accurate than the more common metaphor of scientists patiently piecing together a giant puzzle. With a puzzle you see the manufacturer has guaranteed there is a solution. I know that this view of the scientific process—feeling around in dark rooms, bumping into unidentifiable…
How do you define success? For some, success is a high-paying job, promotions, and financial security. For others, success is finding a rewarding balance between work and personal time. Regardless of how you define success or what your personal goals are, we wrote this text with one purpose: To help you succeed not only in today’s competitive business world, but also in your personal life. A…
Enterprises throughout the ages have always had to deal with processes of change. The invention of printing with movable type almost wholly superseded the medi- eval business model of—usually monastic—scriptoria in the space of just a few decades. Change, therefore, is not a modern phenomenon. Yet what is new is the number and growth of influencing factors that now determine business action…
It is difficult to overstate the importance of computer net- works and cybersecurity in today’s world. They have become such an integral part of our existence that only a moment’s reflection is required to delineate the many ways in which they impact essentially every aspect of our lives. For example, from a personal point of view one need only consider the impact that such things as wirele…
The book is intended for both an academic and a professional audience. As a textbook, it is intended as a one- or two-semester undergraduate course for computer science, computer engineering, and electrical engineering majors. This edition is designed to support the rec- ommendations of the ACM/IEEE Computer Science Curricula 2013 (CS2013). The CS2013 curriculum recommendation includes, for the…
The topic of variable selection in high-dimensional spaces (often with hundreds or thousands of dimensions) has attracted considerable attention in data mining re- search in previous years, and it is common in many real problems. In a nutshell, feature selection is a process that chooses an optimal subset of features according to a certain criterion. The selection of the criterion must be done…
Making money demands effort, whether working for a salary or investing. You get nothing for nothing. Anyone who tells you the stock market is an absolute doddle, and money for old rope, is either a conman or a fool. And the proof of that became very clear with the stock market depressions starting in 2007. But doing a bit of work does not necessarily mean heavy mathematics and several hours eve…
Having originated in the advanced economies, the Global Financial Crisis (GFC) of 2008–09 spread rapidly to the rest of the world. The impact on the emerging markets, especially those in Asia, though not as severe as that in the advanced countries, was still quite signifi- cant. India withstood the crisis initially but could not remain entirely unaffected for long (especially after the collap…
Algorithm is used to define the notion of decidability. It is a set of rules that precisely defines a sequence of operations. This is essential for computers to process information. Computer programs contain algorithms that detail specific instructions a computer should perform to carry out a specified task. The traditional computer program performs specific instructions sequentially, and use…
There are two general goals in this book. Assuming the reader has had no prior training in statistics, the first is to provide a graduate-level introduction to basic, routinely used statistical techniques relevant to the social and behavioral sciences. As can be seen from the Table of Contents, a wide range of topics is covered. Included is a nontechnical description of three major insights reg…
Discrete-time signal processing has appeared to be one of the major momenta to the advances of science and engineering over the past several decades be- cause of the rapid progress of digital and mixed-signal integrated circuits in processing speed, functionality, and cost effectiveness. In many science and engineering applications, the signals of interest are distorted by an unknown physical s…
We wrote a second edition of this book for two reasons. First, the Statistics Toolbox for MATLAB® has been significantly expanded since the first edition, so the text needed to be updated to reflect these changes. Second, we wanted to incorporate some of the suggested improvements that were made by several of the reviewers of the first edition. In our view, one of the most important issues t…
The Internet, as well as other telecommunication networks and information systems, have become an integrated part of our daily lives, and our dependency upon their underlying infrastructure is ever-increas- ing. Unfortunately, as our dependency has grown, so have hostile attacks on the cyber infrastructure by network predators. The lack of security as a core el- ement in the initial design of…
How can we engage in a market relationship when the quality of the goods we want to acquire is unknown, invisible, or uncertain? This is the question addressed in this book. Each chapter focuses on situations where quality is highly uncertain: such situations provide excellent opportunities to analyze how quality is the outcome of a construction process involving producers, consumers, and marke…
By now pretty much everybody in the web world has heard of responsive web design (often referred to as RWD), but a surprising number don’t have a good understanding of what it is . In this chapter, you’ll learn the basics of what it means for a website to be responsive . After that, we’ll go through a little of the history of web design, so you can understand where the idea of responsi…
For all types of businesses, there is an increasing trend towards the utilization of data, as well as information that can be gathered from data. Big Data or Data Scientist are the new terms that emerged from recent developments in the field of data and information science, just to mention a couple examples. The assurance of data quality has become an integral part of information management pr…
My wish to make this book available to an English-speaking audience finally came true. Had it not been for a chance encounter with Francisco J. Ricardo through an introduction by Candy Coleman at a museum opening in Los Angeles in 2011, this book would probably not exist. Francisco’s enthusiasm and support, along with his wonderful contacts Katie Gallof at Bloomsbury and Jörgen Schäfer,…
