Existence of huge amounts of data on the Web has developed an undeferring need to locate right information at right time, as well as to integrating information effectively to provide a comprehensive source of relevant information. There is a need to develop efficient tools for analyzing and managing Web data, and efficiently managing Web information from the database perspective. The book proposes a data model called WHOM (Warehouse Object Model) to represent HTML and XML documents in the warehouse. It defines a set of web algebraic operators for building new web tables by extracting relevant...

Starting with fingerprints more than a hundred years ago, there has been ongoing research in biometrics. Within the last forty years face and speaker recognition have emerged as research topics. However, as recently as a decade ago, biometrics itself did not exist as an independent field. Each of the biometric-related topics grew out of different disciplines. For example, the study of fingerprints came from forensics and pattern recognition, speaker recognition evolved from signal processing, the beginnings of face recognition were in computer vision, and privacy concerns arose from the...

Software testing is rapidly evolving as a critical sub-discipline of software engineering. The industry needs professionals educated in the modern methods and tools of software testing and quality assurance. Based on the needs of software professionals, "Practical Software Testing" takes a unique approach to teaching readers how to effectively plan for testing, design test cases, test at multiple levels, organize a testing team, and optimize use of testing tools. It introduces testing concepts that are managerial-, technical-, and process-oriented, using the Testing Maturity Model (TMM) as a...

of the Architecture Forum, and to the evolution of TOGAF, to ensure that others make a fair contribution in return. So much for legal necessities. I turn now to the additional information and resources that I hope the reader will ?nd of interest. The Development of TOGAF TOGAF has come a long way since its inception in 1994 at the instigation of The Open Group s User Council (as it then was) representatives of the computer user community among The Open Group membership. The original motivations for TOGAF were very much as Tony and Col have expounded so eloquently in the early chapters of this...

The Unified Modeling Language (UML) is an evolutionary general-purpose, tool-supported, and industry-standardized (OMG) modeling language for specifying, visualizing, constructing, and documenting the artifacts of a system-intensive process. "Guide to Applying the UML" offers a practical bridge between tutorials and reference works, demonstrating how all of the elements of the UML fit together holistically and cohesively. It closes the gap between the UML and process using a roadmap that addresses the key decision points and their relationships, providing a comprehensive framework. The focus...

Overview At the beginning of 1999, Springer-Verlag published the book Open Geo- try OpenGL +Advanced Geometry. There, the authors Georg Glaeser and Hellmuth Stachel presented a comprehensive library of geometric me- odsbasedonOpenGLroutines.AnaccompanyingCD-ROMprovidedthesource code and many sample ?les. Many diverse topics are covered in this book. The theoretical background is carefully explained, and many examples are given. Since the publication of Open Geometry, the source code has been improved andmanyadditionalfeatureshavebeenaddedtotheprogram.Contributorsfrom...

After two decades of research and development, elliptic curve cryptography now has widespread exposure and acceptance. Industry, banking, and government standards are in place to facilitate extensive deployment of this efficient public-key mechanism.

Anchored by a comprehensive treatment of the practical aspects of elliptic curve cryptography (ECC), this guide explains the basic mathematics, describes state-of-the-art implementation methods, and presents standardized protocols for public-key encryption, digital signatures, and key establishment. In addition, the book...

Developments in technology have made it possible for speech output to be used in place of the more usual visual interface in both domestic and commercial devices. Speech can be used in situations where visual attention is occupied, such as when driving a car, or where a task is complex and traditional visual interfaces are not effective, such as programming a video recorder. Speech can also be employed in specialist adaptations for visually impaired people.

However, the use of speech has not been universally successful, possibly because the speech interaction is poorly designed....

In this book, John Hunt and Chris Loftus take you through the core technologies that make up the Enterprise Edition of the Java 2 platform (J2EE). They cover all the aspects of J2EE that both professionals and students need to know to build multi-tier enterprise applications in Java - the technologies, the design methodology and design patterns. Whether you are a professional or student, this book will help equip you with the skills you need to build enterprise wide applications in Java. Key Topics Includes design issues using J2EE patterns Covers all parts of the enterprise application J2EE...
