Essential C# 2.0 is a clear, concise guide to C#—including the features new to C# 2.0. The book clearly presents material for beginners and experts and provides contrasts and comparisons between C# and other languages. The C# language is covered comprehensively and each important construct is illustrated with succinct code examples. Complete code examples are available online. Mark Michaelis has organized the material for quick access. Graphical “mind maps” at the beginning of each chapter show what material is covered and how each topic relates to the whole.

“[This] is a book about design in the .NET world, driven in an agile manner and infused with the products of the enterprise patterns community. [It] shows you how to begin applying such things as TDD, object relational mapping, and DDD to .NET projects...techniques that many developers think are the key to future software development.... As the technology gets more capable and sophisticated, it becomes more important to understand how to use it well. This book is a valuable step toward advancing that understanding.”

Do formulas exist for the solution to algebraical equations in one variable of any degree like the formulas for quadratic equations? The main aim of this book is to give new geometrical proof of Abel's theorem, as proposed by Professor V.I. Arnold. The theorem states that for general algebraical equations of a degree higher than 4, there are no formulas representing roots of these equations in terms of coefficients with only arithmetic operations and radicals. A secondary, and more important aim of this book, is to acquaint the reader with two very important branches of modern mathematics: group theory and theory of functions of a complex variable. This book also has the added bonus of an extensive appendix devoted to the differential Galois theory, written by Professor A.G. Khovanskii. As this text has been written assuming no specialist prior knowledge and is composed of definitions, examples, problems and solutions, it is suitable for self-study or teaching students of mathematics, from high school to graduate.

The theory of D-modules is a rich area of study combining ideas from algebra and differential equations, and it has significant applications to diverse areas such as singularity theory and representation theory. This book introduces D-modules and their applications, avoiding all unnecessary technicalities. The author takes an algebraic approach, concentrating on the role of the Weyl algebra. The author assumes very few prerequisites, and the book is virtually self-contained. The author includes exercises at the end of each chapter and gives the reader ample references to the more advanced literature. This is an excellent introduction to D-modules for all who are new to this area.

This book, an outgrowth of the author¿s lectures at the University of California at Berkeley, is intended as a textbook for a one-semester course in basic ring theory. The material covered includes the Wedderburn-Artin theory of semisimple rings, Jacobson¿s theory of the radical, representation theory of groups and algebras, prime and semiprime rings, local and semilocal rings, perfect and semiperfect rings, etc. By aiming the level of writing at the novice rather than the connoisseur and by stressing the role of examples and motivation, the author has produced a text that is suitable not only for use in a graduate course, but also for self-study in the subject by interested graduate students. More than 400 exercises testing the understanding of the general theory in the text are included in this new edition.

This classic book provides a broad introduction to homological algebra, including a comprehensive set of exercises. Since publication of the first edition homological algebra has found a large number of applications in many different fields. Today, it is a truly indispensable tool in fields ranging from finite and infinite group theory to representation theory, number theory, algebraic topology and sheaf theory. In this new edition, the authors have selected a number of different topics and describe some of the main applications and results to illustrate the range and depths of these developments. The background assumes little more than knowledge of the algebraic theories groups and of vector spaces over a field.

This book contains the proceedings of the IFIP TC8 Working Conference on Mobile Information Systems, which was held in September 2004 in Oslo, Norway and sponsored by the International Federation for Information Processing (IFIP).

With its celebrated success and proven results, the Six Sigma quality improvement methodology has expanded from its origins in the engineering industry to transform a wide variety of businesses, along the way developing a particular focus on customer service and satisfaction. While this evolution may seem to imply a shift of attention to the "ground floor" business-client interface, Six Sigma expert D. H. Stamatis draws his readers to the very peak of the organizational chart, explaining how executives and leaders make or break Six Sigma success with their every action and decision. Six Sigma for Financial Professionals is a comprehensive quality improvement guide for the financial industry, explaining the practice of Six Sigma methodology from top to bottom.

Books on the beta releases of software have sold extremely well, when they are on an important software release, even though very few of them have had any solid or original content. Microsoft has come to AW, and our authors, to produce a book on the beta release of their next version of SQL Server.

Surprise is rarely a good thing in business. Unexpected developments range in their effects from inconvenient to disastrous. To avoid being blindsided, companies must develop a Competitive Early Warning system, or CEW, which combines strategic planning, competitive intelligence, and management action. Such systems let organizations manage risk more effectively and prevent "industry dissonance" -- when market realities outpace corporate strategies.

Medicine Across Cultures: The History and Practice of Medicine in Non-Western Cultures consists of 19 essays dealing with the medical knowledge and beliefs of cultures outside of the United States and Europe. In addition to articles surveying Islamic, Chinese, Native American, Aboriginal Australian, Indian, Egyptian, and Tibetan medicine, the book includes essays on comparing Chinese and western medicine and religion and medicine. The essays address the connections between medicine and culture and relate the medical practices to the cultures which produced them. Each essay is well illustrated and contains an extensive bibliography. Because the geographic range is global, the book fills a gap in both the history of medicine and in cultural studies. It should find a place on the bookshelves of advanced undergraduate students, graduate students, and scholars, as well as in libraries serving those groups.
