A concise, "no-frills" introduction to quantum computation and quantum cryptography for non-experts. Rather than concentrating on stories about scientists and philosophical concepts, Quantum Bits and Quantum Secrets: How Quantum Physics is revolutionizing Codes and Computers provides a step-by-step approach to quantum information. Starting from the idea of quantum cryptography, it presents the basic principles of quantum mechanics and explains how this can be used to make cryptography absolutely secure against eavesdropping. Subsequently, the most important quantum algorithms are explained and technical problems in realizing quantum computers are discussed, followed by a presentation of recent experiments—some of which are found here in a textbook for the first time. Easily accessible for undergraduates and graduates—especially those studying subjects other than physics—who need an introduction to this rapidly developing topic.

Large-scale attacks generated by fast spreading worms and viruses have emerged as a major threat to the Internet. These worms are capable of infecting and crippling substantial portions of the Internet as well as the enterprise networks of large public and private agencies in a very short time. This dissertation work studies the behavior of such viruses and examines the problem of their detection and containment. It develops a simulation testbed to study the propagation and threat potentials of self- propagating viruses. Using the testbed, a new approach is developed for detecting self-propagating worms/viruses based on statistical anomaly detection. The approach assumes that a key characteristic of a worm/virus attack is an increase in application based network traffic, which will eventually overwhelm servers and clients. The effectiveness of the detection approach has been tested for email based viruses in an intranet setting. The report concludes with results of experiments using a novel approach for cleaning up virus infections, based on the model of "predators" in an ecosystem.

This book is an introduction to the current concepts, applications and tools of information technology. No previous knowledge of the underlying and engineering ideas is required, making it invaluable to specialists and non-specialists alike.

The Little Windows 98 Book is the best, most inviting place to start learning about Windows 98. If you're a computer beginner, you'll love its entertaining style and easy-to-understand explanations written by critically acclaimed, best-selling author Alan Simpson, and the accompanying humorous illustrations by John Grimes. As part of Peachpit's popular "Little"series, The Little Windows 98 Book doesn't bog you down with lots of jargon and endless pages of dry technical details, but rather spotlights the essentials so you can get to work quickly. You'll find basics such as using menus and dialog boxes, creating files and folders, and working with the desktop, as well as explanations on how to install new programs, send and manage email, and explore the Internet. If you're a beginning computer user, there's no easier way to get started with Microsoft Windows 98.

L'analyse numérique de deux types de discrétisations variationnelles est effectuée en détail pour des problèmes elliptiques: les méthodes spectrales et les méthodes d'éléments finis. Les avantages de chaque type sont mis en valeur, et leur mise en oeuvre est décrite. L'originalité de cet ouvrage est d'insérer ces deux types de discrétisation dans un cadre abstrait commun, ce qui permet au lecteur d'étendre l'approche à bien d'autres méthodes et problèmes. Sont présentés également un algorithme pour coupler ces méthodes dans un cadre de décomposition de domaine et une application aux écoulements de fluides incompressibles dans des milieux poreux. L'ouvrage s'adresse aux étudiants de 3ème cycle en mathématiques appliquées et mécanique, ainsi qu'à tous les ingénieurs intéressés par la simulation numérique.

This work is designed for use in the concepts portion of an introductory course on microcomputing. Along with concepts, this text considers word processing, spreadsheets, database software packages, desktop publishing and computer graphics.

Based on the authors' experience of the way in which people really learn, this book presents an innovative approach to acquiring and developing IT skills. Readers are encouraged to learn through practical means and through guided exploration, helping to build confidence for further exploration.
