Elements of Data Compression
Today's increased use of digital sound and video makes data compression crucial to computer technology because of its vast storage and transmission requirements. The question in many applications is now not whether to compress data, but what compression method should be applied. Most data compression books have been written for professionals and require a strong background in data compression techniques as well as an understanding of algorithms based on sophisticated mathematical models. This book is one of a handful of textbooks to present Data Compression for students in an academic environment. This is not a simple task since most of the widely used algorithms rely on sophisticated mathematical models. ELEMENTS OF DATA COMPRESSION addresses the needs of students who will use these techniques on a daily basis. The author accomplishes this through the use of elementary-level representative methods of text, audio, and video compression. Drozdek presents these methods with pseudocode, tables, diagrams, and many worked out examples, all the while employing commonly used techniques that build upon the mathematics students have been exposed to in earlier courses.
viii • The second new chapter, Chapter 6, discusses video compression. The chapter opens with a general description of CRT operation and basic analog and digital video concepts. It continues with a general discussion of video compression, and it concludes with a description of MPEG-1 and H.261. • Audio compression is the topic of the third new chapter, Chapter 7. The first topic in this chapter is the properties of the human audible system and how they can be exploited to achieve lossy audio compression. A discussion of a few simple audio compression methods follows, and the chapter concludes with a description of the three audio layers of MPEG-1, including the very popular mp3 format. Other new material consists of the following: • Conditional image RLE (Section 1.4.2). • Scalar quantization (Section 1.6). • The QM coder used in JPEG, JPEG 2000, and JBIG is now included in Sec tion 2.16. • Context-tree weighting is discussed in Section 2.19. Its extension to lossless image compression is the topic of Section 4.24. • Section 3.4 discusses a sliding buffer method called repetition times. • The troublesome issue of patents is now also included (Section 3.25). • The relatively unknown Gray codes are discussed in Section 4.2.1, in connection with image compression. • Section 4.3 discusses intuitive methods for image compression, such as subs- pling and vector quantization.
Data Structures and Algorithms in Java
Using the Java programming language, author Adam Drozdek highlights three important aspects of data structures and algorithms. First, the book places special emphasis on the connection between data structures and their algorithms, including an analysis of the algorithms’ complexity. Second, the book presents data structures in the context of object-oriented program design, stressing the principle of information hiding in its treatment of encapsulation and decomposition. Finally, the book closely examines data structure implementation. Overall, this practical and theoretical book prepares students with a solid foundation in data structures for future courses and work in design implementation, testing, or maintenance of virtually any software system.

Handbook of Data Compression
Data compression is one of the most important fields and tools in modern computing. From archiving data, to CD-ROMs, and from coding theory to image analysis, many facets of modern computing rely upon data compression. This book provides a comprehensive reference for the many different types and methods of compression. Included are a detailed and helpful taxonomy, analysis of most common methods, and discussions on the use and comparative benefits of methods and description of "how to" use them. Detailed descriptions and explanations of the most well-known and frequently used compression methods are covered in a self-contained fashion, with an accessible style and technical level for specialists and non-specialists.
Trauma Rehabilitation After War and Conflict
"As foreign assistance flows into post-conflict regions to rebuild economies, roads, and schools, it is important that development professionals retain a focus on the purely human element of rebuilding lives and societies. This book provides perspective on just how to begin that process so that the trauma people suffered is not passed on to future generations long after the violence has stopped." - Amy T. Wilson, Ph.D., Gallaudet University, Washington, DC "This ground-breaking text provides the reader with an excellent and comprehensive overview of the existing field of trauma rehabilitation. It also masterfully navigates the intricate relationships among theory, research, and practice leaving the reader with immense appreciation for its subject matter." - Hanoch Livneh, Hanoch Livneh, Ph.D., LPC, CRC, Portland State University Fear, terror, helplessness, rage: for soldier and civilian alike, the psychological costs of war are staggering. And for those traumatized by chronic armed conflict, healing, recovery, and closure can seem like impossible goals. Demonstrating wide-ranging knowledge of the vulnerabilities and resilience of war survivors, the collaborators on Trauma Rehabilitation after War and Conflict analyze successful rehabilitative processes and intervention programs in conflict-affected areas of the world. Its dual focus on individual and community healing builds on the concept of the protective "trauma membrane," a component crucial to coping and healing, to humanitarian efforts (though one which is often passed over in favor of rebuilding infrastructure), and to promoting and sustaining peace. The book’s multiple perspectives—including public health, community-based systems, and trauma-focused approaches—reflect the complex psychological, social, and emotional stresses faced by survivors, to provide authoritative information on salient topics such as: Psychological rehabilitation of U.S. veterans, non-Western ex-combatants, and civilians Forgiveness and social reconciliation after armed conflict Psychosocial adjustment in the post-war setting Helping individuals heal from war-related rape The psychological impact on prisoners of war Rehabilitating the child soldier Rehabilitation after War and Conflict lucidly sets out the terms for the next stage of humanitarian work, making it essential reading for researchers and professionals in psychology, social work, rehabilitation, counseling, and public health.
Handbook of Data Structures and Applications
Although there are many advanced and specialized texts and handbooks on algorithms, until now there was no book that focused exclusively on the wide variety of data structures that have been reported in the literature. The Handbook of Data Structures and Applications responds to the needs of students, professionals, and researchers who need a mainstream reference on data structures by providing a comprehensive survey of data structures of various types. Divided into seven parts, the text begins with a review of introductory material, followed by a discussion of well-known classes of data structures, Priority Queues, Dictionary Structures, and Multidimensional structures. The editors next analyze miscellaneous data structures, which are well-known structures that elude easy classification. The book then addresses mechanisms and tools that were developed to facilitate the use of data structures in real programs. It concludes with an examination of the applications of data structures. The Handbook is invaluable in suggesting new ideas for research in data structures, and for revealing application contexts in which they can be deployed. Practitioners devising algorithms will gain insight into organizing data, allowing them to solve algorithmic problems more efficiently.
Fundamentals of Programming Languages
" .. .1 always worked with programming languages because it seemed to me that until you could understand those, you really couldn't understand computers. Understanding them doesn't really mean only being able to use them. A lot of people can use them without understanding them." Christopher Strachey The development of programming languages is one of the finest intellectual achievements of the new discipline called Computer Science. And yet, there is no other subject that I know of, that has such emotionalism and mystique associated with it. Thus my attempt to write about this highly charged subject is taken with a good deal of caution. Nevertheless, in my role as Professor I have felt the need for a modern treatment of this subject. Traditional books on programming languages are like abbreviated language manuals, but this book takes a fundamentally different point of view. I believe that the best possible way to study and understand today's programming languages is by focusing on a few essential concepts. These concepts form the outline for this book and include such topics as variables, expressions, statements, typing, scope, procedures, data types, exception handling and concurrency. By understanding what these concepts are and how they are realized in different programming languages, one arrives at a level of comprehension far greater than one gets by writing some programs in a vi vB Preface few languages. Moreover, knowledge of these concepts provides a framework for understanding future language designs.
