Coding is an highly integral component of viable and efficient computer and data communications, yet the often heavy mathematics that form the basis of coding can prevent a serious and practical understanding of this important area.
"Coding for Data and Computer Communications" eschews the complex mathematics and clearly describes the core concepts, principles, and methods of channel codes ( for error correction), source codes (for compressing data), and secure codes (for cryptography, data hiding, and privacy). Conveniently organized and segmented into three associated parts for...

In 1829, Louis Braille, a young organist in a Paris church, blind since age 3, invented the well-known code for the blind, still in common use today all over the world and named after him. Braille himself modified his code in 1834, and there have been several modifications since. However, the basic design of this code, where each character is represented by a group of 3 x 2 dots, has remained intact. The dots are embossed on thick paper and each can be raised or flat (i. e., present or absent). Each dot is therefore equivalent to one bit of information. As a result, the Braille code (Figure...

Anyone with a computer has heard of viruses, had to deal with several, and has been struggling with spam, spyware, and disk crashes. This book is intended as a starting point for those familiar with basic concepts of computers and computations and who would like to extend their knowledge into the realm of computer and network security. Its comprehensive treatment of all the major areas of computer security aims to give readers a complete foundation in the field of Computer Security. Exercises are given throughout the book and are intended to strengthening the reader s knowledge - answers...

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...

"Why is 'lEX so hard to use?" is the most frequent comment/complaint made by (frustrated) 'lEX users. The answer: Because it is programmable (has many features commonly found in programming languages), because it pays attention to detail, and because its creator has developed it for his own use (perhaps also his administrative assistant's) and not for general use. The material presented here is a direct result of this complaint and is an attempt to make it easier for inexperienced users to get the kind of high-quality typesetting that is possible with 'lEX. The material is based on classes...
