Review Structuring Data and Building Algorithms: An ANSI-C Based Approach / McGraw-Hill Education (Asia):The famous mathematician, physicist, theologian, and philosopher Sir Isaac Newton (1642–1727) once wrote, “If I have seen further [than certain other people], it is by standing on the shoulders of giants. ” This is very true in computer programming as well. Imagine if all programmers had to rediscover for themselves by trial and error how to solve common problems in programming! It is much better to learn the solutions that other programmers have already discovered and build upon that foundation. This book is about those foundational solutions. It describes how to structure data and build algorithms to solve common programming tasks. Some of these techniques have names that come from ordinary non-computer life – e. g. stacks, queues and sorting – and others have names that might be completely unfamiliar to a new student of programming – e. g. recursion, backtracking and arrays – but they are all standards in the programmer’s tool chest. [+]Occasionally, a new tool is discovered – or at least, refined – and we include one which was just discovered in 1999 – introspective sort. But most of them have been part of the standard programmer’s tool chest for decades. Unlike the majority of textbooks in this field, this book takes a “code first” approach. After a brief introduction of the concepts, a short complete ANSI-C program is presented for students to analyse. A number of questions arising from the code are then posed and answered in the Socratic format. In this way, we hope that the reader will not only become fluent in the concepts but also in the “nuts and bolts” of translating these concepts into functioning, efficient standard C code. Variable pointer diagrams are developed and used extensively to aid understanding of the more complex data structures and their manipulation.

Review Multimedia Mining: A Highway to Intelligent Multimedia Documents (Multimedia Systems and Applications) / Springer:The conjunction of knowledge discovery and multimedia documents presents a very important challenge. This new field of knowledge discovery in multimedia documents, dealing with non-structured information such as texts, images, videos, audio and virtual data, requires the collaboration of experts in many areas of interest revolving around document management systems, data mining, visual computing, signal processing, multimedia data and machine learning. Multimedia Mining: A Highway to Intelligent Multimedia Documents will bring together experts in digital media content analysis, state-of-art data mining and knowledge discovery in multimedia database systems, knowledge engineers and domain experts from diverse applied disciplines. Multimedia documents are ubiquitous and often required, if not essential, in many applications today. This phenomenon has made multimedia documents widespread and extremely large. There are tools for managing and searching within these collections, but the need for tools to extract hidden useful knowledge embedded within multimedia objects is becoming pressing and central for many decision-making applications. The tools needed today are tools for discovering relationships between objects or segments within multimedia document components, such as classifying images based on their content, extracting patterns in sound, categorizing speech and music, and recognizing and tracking objects in video streams. Multimedia Mining: A Highway to Intelligent Multimedia Documents is designed to meet the needs of a professional audience composed of researchers and practitioners in industry and graduate-level students in computer science and engineering.

Review Higher Recursion Theory (Perspectives in Mathematical Logic) / Springer:Hyperarithmetic theory is the first step beyond classical recursion theory. It is the primary source of ideas and examples in higher recursion theory. It is also a crossroad for several areas of mathematical logic: in set theory it is an initial segment of Godel's L; in model theory, the least admissible set after ; in descriptive set theory, the setting for effective arguments. In this book, hyperarithmetic theory is developed at length and used to lift classical recursion theory from integers to recursive ordinals (metarecursion). Two further liftings are then made, first ordinals ( -recursion) and then to sets (E-recursion). Techniques such as finite and infinite injury, forcing and fine structure and extended and combined Dynamic and syntactical methods are contrasted. Several notions of reducibility and computation are compared. Post's problem is answere affirmatively in all three settings. This long-awaited volume of the -series will be a "Must" for all working in the field.

Review Performance Analysis and Grid Computing / Springer:Past and current research in computer performance analysis has focused primarily on dedicated parallel machines. However, future applications in the area of high-performance computing will not only use individual parallel systems but a large set of networked resources. This scenario of computational and data Grids is attracting a great deal of attention from both computer and computational scientists. In addition to the inherent complexity of parallel machines, the sharing and transparency of the available resources introduces new challenges on performance analysis, techniques, and systems. In order to meet those challenges, a multi-disciplinary approach to the multi-faceted problems of performance is required. New degrees of freedom will come into play with a direct impact on the performance of Grid computing, including wide-area network performance, quality-of-service (QoS), heterogeneity, and middleware systems, to mention only a few. Reflecting this new reality, the Dagstuhl Workshop on Performance Analysis and Distributed Computing, organized by members of the European Working Group APART, was designed to bring together researchers from both the high-performance computing and the distributed computing areas. Indeed, attendees with expertise in a variety of topics in computer and computational sciences arrived in Dagstuhl at the end of August 2002 to discuss the state-of-the-art and the future of computer performance research as it applies to systems, applications, and Grids. Performance Analysis and Grid Computing comprises selected contributions encapsulating this scientifically rich event. The articles are organized in three parts: Performance Modeling and Analysis, Performance Tools and Systems, and Grid Performance and Applications. [+]It will provide invaluable reading for researchers and developers in the areas of performance analysis, high-end computer systems, and Grid computing.
