This book is aimed at programmers who have learned the basics of Java from, for example, Beginning Java 1.4: From Novice to Professional, and are now ready to learn how to use Java in the real world, with J2EE. But, J2EE is a big spec, and the target audience is not interested in Enterprise JavaBeans and other advanced specs within J2EE. In fact, 75% of J2EE applications are built using only JavaServer Pages and Servlets (two of the simpler technologies to learn in J2EE), so these are the areas that the audience is particularly interested in. Download Description The Java 2 Enterprise Edition (J2EE) is an extremely powerful platform for developing enterprise-level Java-based applications for primarily the server. In order to harness that power, you need to know how to properly use the API in the J2EE platform. In this book, Weaver, Mukhar, and Crume give you an overview of how the pieces of the J2EE platform work together and complement each other. This book goes further than just showing you how to code a JSP or an EJB: This book explains when and where to use these APIs, their strengths and weaknesses, and best practices for using them. This book explores * Creating dynamic clients using JSP and servlets * Connecting and using databases through Java Database Connectivity (JDBC) * Implementing a business tier using EJB * Using Web services and XML in your enterprise applications This book also contains hands-on tutorials, clear explanations, and working co Read more...

Spacetime and Geometry: An Introduction to General Relativity provides a lucid and thoroughly modern introduction to general relativity. With an accessible and lively writing style, it introduces modern techniques to what can often be a formal and intimidating subject. Readers are led from the physics of flat spacetime (special relativity), through the intricacies of differential geometry and Einstein's equations, and on to exciting applications such as black holes, gravitational radiation, and cosmology. For advanced undergraduates and graduate students, or anyone interested in astronomy, cosmology, physics, or general relativity. Read more...

Cohesive presentation of power electronics fundamentals for applications and design in the power range of 500 kW or less. Describes a variety of practical and emerging power electronic converters made feasible by the new generation of power semiconductor devices. This revised edition includes an expanded discussion of diode rectifiers and thyristor converters as well as new chapters on heat sinks, magnetic components which present a step-by-step design approach and a computer simulation of power electronics which introduces numerical techniques and commonly used simulation packages such as PSpice, MATLAB and EMTP. Contains a significantly expanded set of end-of-chapter problems. Reviews Summary: Had What I needed. Rating: 5 Although a little light on full converter schematics, this textbook contained excellent descriptions of converter building blocks and semiconductor device physics. It is excellent that it came with a simulator program too. Summary: Great book in power electronics Rating: 5 There is a ton of information on three-phase power electronics, converters, and etc. I feel guilty for not being able (time wise) to read all of it. Summary: Good overview ... a bit thin on some subjects Rating: 3 Good power electronics textbook. I use it for my power electronics course at Worcester Polytechnic Institute. It covers a lot of material well, including switching power converters, thermal and magnetics design. It's a bit thin in some important subjects Read more...

Anyone who has studied "abstract algebra" and linear algebra as an undergraduate can understand this book. This edition has been completely revised and reorganized, without however losing any of the clarity of presentation that was the hallmark of the previous editions. The first six chapters provide ample material for a first course: beginning with the basic properties of groups and homomorphisms, topics covered include Lagrange's theorem, the Noether isomorphism theorems, symmetric groups, G-sets, the Sylow theorems, finite Abelian groups, the Krull-Schmidt theorem, solvable and nilpotent groups, and the Jordan-Holder theorem. The middle portion of the book uses the Jordan-Holder theorem to organize the discussion of extensions (automorphism groups, semidirect products, the Schur-Zassenhaus lemma, Schur multipliers) and simple groups (simplicity of projective unimodular groups and, after a return to G-sets, a construction of the sporadic Mathieu groups).
