Coding is a highly integral component of viable and efficient computer and data communications, yet the often heavy mathematics that form the basis of coding may prevent a serious and practical understanding of this important area. Coding for Data and Computer Communications avoids the complex mathematics, favoring the core concepts, principles, and methods of channel codes (for error correction), source codes (for compressing data), and secure codes (for data privacy). The most important approaches and techniques used to make the storage and transmission of information (data) fast, secure, and reliable are examined. This book is an essential resource for all security researchers and professionals who need to understand and effectively use coding employed in computers and data communications. Anchored by a clear, nonmathematical exposition, all the major topics, principles, and methods are presented in an accessible style suitable for professional specialists, nonspecialists, students, and individual self-study.

Why is TeX so hard to use? Because it is in essence a programming language and so it is best viewed from this perspective. In this book, the author presents a complete course in TeX which will be suitable for users of TeX who want to advance beyond the basics. The initial chapters introduce the essential workings of TeX, including a detailed discussion of boxes and glue. Later chapters cover a wide range of advanced topics such as: macros, conditionals, tokens, leaders, file I/O, the line- and page-break algorithms, and output routines. Throughout, numerous examples are given and exercises (with answers) provide a means for readers to test their understanding of the material. As a result, no serious user of TeX will want to be without this text.

Joseph-Louis Lagrange (1736-1813), one of the greatest mathematicians of the 18th century, made important contributions to the theory of numbers and to analytical and celestial mechanics. His most important work is Mecanique Analytique (1788), the textbook on which all subsequent work in this field is based. A contempo­ rary reader is surprised to find no diagrams or figures of any kind in this book on mechanics. This reflects one extreme approach to graphics, namely considering it unimportant or even detracting as a teaching tool and not using it. Today, of course, this approach is unthinkable. Graphics, especially computer graphics, is commonly used in texts, advertisements, and movies to illustrate concepts, to emphasize points being discussed, and to entertain. Our approach to graphics has been completely reversed since the days of La­ grange, and it seems that much of this change is due to the use of computers. Computer graphics today is a mature, successful, and growing field. Itis used by many people for many purposes and it is enjoyed by even more people. One criterion for the maturity of a field of study is its size. When a certain discipline becomes so big that no one person can keep all of it in their head, we say that that discipline has matured (or has come of age). This is what happened to computer graphics in the last decade or so.

It is probably a coincidence that the three main terms discussed in this book, namely transformations, projections,and perspective, are ambiguous. Here is what the dict- nary has to say about these terms. Transformation (a) The act or an instance of transforming. (b) The state of being transformed. A marked change, as in appearance or character, usually for the better. Mathematical transformation. (a) Replacing a variable in an expression by its value. (b) Mapping a mathematical space onto another or onto itself. In geometry. Moving, rotating, re?ecting, or otherwise systematically deforming a geometric ?gure (discussed in this book). In linguistics. (a) A rule to convert a syntactic form into another. (b) A sentence or sentential form derived by such a rule; a transform. In genetics. (a) The change undergone by a cell upon infection by a cancer-causing virus. (b) The alteration of a bacterial cell caused by the transfer of DNA from another bacterial cell, especially a pathogen. Projection The act of projecting or the condition of being projected. (a) An object or part thereof that extends outward. (b) Spiky projections on top of a fence. (c) A projection of land along the coast. A prediction or an estimate of a future situation, based on current data or trends. (a) The process of projecting a recorded image onto a viewing surface. (b) An image so projected.

Most data compression methods that are based on variable-length codes employ the Huffman or Golomb codes. However, there are a large number of less-known codes that have useful properties - such as those containing certain bit patterns, or which are robust - and these can be useful. This book brings this large set of codes to the attention of workers in the field and of students of computer science.David Salomon’s crystal clear style of writing and presentation, which has been familiar to readers for many years now allows easy access to the topic. Readers are only required to have a general familiarity with computer methods and essentially an understanding of the representation of data in bits and files.Computer scientists, electrical engineers and students majoring in computer science or electrical engineering will find this volume an invaluable resource, as will those readers in various physical sciences and mathematics.

Compression is an option naturally selected when faced with problems of high costs or restricted space. This book offers readers a succinct and reader-friendly foundation to the most important topics in the field of data compression.Divided into two parts, Part I presents the basic approaches to data compression and describes a few popular techniques and methods that are commonly used to compress data. The reader discovers essential concepts, such as variable-length and prefix codes, statistical distribution and run-length codes. Part II concentrates on advanced techniques, such as arithmetic coding, orthogonal transforms, subband transforms and Burrows-Wheeler transform.Complete and clear, this book will be the perfect reference for advanced undergraduates in computer science and requires a minimum of mathematics. An author-maintained website provides readers with errata and auxiliary material.

Data compression is one of the most important fields and tools in modern computing. From archiving data, to CD-ROMs, and from coding theory to image analysis, many facets of modern computing rely upon data compression. This book provides a comprehensive reference for the many different types and methods of compression. Included are a detailed and helpful taxonomy, analysis of most common methods, and discussions on the use and comparative benefits of methods and description of "how to" use them. Detailed descriptions and explanations of the most well-known and frequently used compression methods are covered in a self-contained fashion, with an accessible style and technical level for specialists and non-specialists.

Its comprehensive treatment of all the major areas of computer security aims to give readers a complete foundation in the field of Computer Security.
