Taschenbuch. Zustand: Neu. Neuware - Youth have nearly always exhibited behaviors that frustrate adults. It can be diffi cult to understand why young people engage in risky or destructive behavior, and it is challenging to develop strategies to encourage more healthy and responsible behavior among our youth. However, it is helpful to realize that despite the fact that large numbers of youth engage in frightful and destructive behaviors for pe riods of time during adolescence and early adulthood, a large proportion of youth find a way not only to survive but also to bounce back and contribute significantly to the furtherance of human development. We are not the first generation of adults to experience the pain, fear, and frustration of dealing with our youth. More important, we recognize that we are not helpless when faced with the problems youth experience. While it is true that adolescents have always exhibited problem behaviors, a number of effective tools and approaches have always been at our disposal to assist with appropriate youth development. Of course, the most effective approaches require a tremendous amount of focused time and energy.

Buch. Zustand: Neu. Neuware - During the last three decades, interest has increased significantly in the representation and manipulation of imprecision and uncertainty. Perhaps the most important technique in this area concerns fuzzy logic or the logic of fuzziness initiated by L. A. Zadeh in 1965. Since then, fuzzy logic has been incorporated into many areas of fundamental science and into the applied sciences. More importantly, it has been successful in the areas of expert systems and fuzzy control. The main body of this book consists of so-called IF-THEN rules, on which experts express their knowledge with respect to a certain domain of expertise. Fuzzy IF-THEN Rules in Computational Intelligence: Theory and Applications brings together contributions from leading global specialists who work in the domain of representation and processing of IF-THEN rules. This work gives special attention to fuzzy IF-THEN rules as they are being applied in computational intelligence. Included are theoretical developments and applications related to IF-THEN problems of propositional calculus, fuzzy predicate calculus, implementations of the generalized Modus Ponens, approximate reasoning, data mining and data transformation, techniques for complexity reduction, fuzzy linguistic modeling, large-scale application of fuzzy control, intelligent robotic control, and numerous other systems and practical applications. This book is an essential resource for engineers, mathematicians, and computer scientists working in fuzzy sets, soft computing, and of course, computational intelligence.

Buch. Zustand: Neu. Neuware - Field-Programmable Custom Computing Technology: Architectures, Tools, and Applications brings together in one place important contributions and up-to-date research results in this fast-moving area. In seven selected chapters, the book describes the latest advances in architectures, design methods, and applications of field-programmable devices for high-performance reconfigurable systems. The contributors to this work were selected from the leading researchers and practitioners in the field. It will be valuable to anyone working or researching in the field of custom computing technology. It serves as an excellent reference, providing insight into some of the most challenging issues being examined today.

Buch. Zustand: Neu. Neuware - Video segmentation is the most fundamental process for appropriate index ing and retrieval of video intervals. In general, video streams are composed 1 of shots delimited by physical shot boundaries. Substantial work has been done on how to detect such shot boundaries automatically (Arman et aI. , 1993) (Zhang et aI. , 1993) (Zhang et aI. , 1995) (Kobla et aI. , 1997). Through the inte gration of technologies such as image processing, speech/character recognition and natural language understanding, keywords can be extracted and associated with these shots for indexing (Wactlar et aI. , 1996). A single shot, however, rarely carries enough amount of information to be meaningful by itself. Usu ally, it is a semantically meaningful interval that most users are interested in re trieving. Generally, such meaningful intervals span several consecutive shots. There hardly exists any efficient and reliable technique, either automatic or manual, to identify all semantically meaningful intervals within a video stream. Works by (Smith and Davenport, 1992) (Oomoto and Tanaka, 1993) (Weiss et aI. , 1995) (Hjelsvold et aI. , 1996) suggest manually defining all such inter vals in the database in advance. However, even an hour long video may have an indefinite number of meaningful intervals. Moreover, video data is multi interpretative. Therefore, given a query, what is a meaningful interval to an annotator may not be meaningful to the user who issues the query. In practice, manual indexing of meaningful intervals is labour intensive and inadequate.

Buch. Zustand: Neu. Neuware - Membrane fusion and targeting processes are tightly regulated and coordinated. Dozens of proteins, originating from both the cytoplasm and membranes are involved. The discovery of homologous proteins from yeast to neurons validates a unified view. Although much is known about the interfering proteins, the events occurring when two lipid bilayers actually fuse are less clear. It should be remembered that lipid bilayers behave like soap-bubbles fusing when meeting each other. In this respect interfering proteins should be considered as preventing undesirable and unnecessary fusion and eventually directing the biological membrane fusion process (when, where, how, and overcoming the activation energy). In this latest volume in the renowned Subcellular Biochemistry series, some aspects of fusion of biological membranes as well as related problems are presented. Although not complete, there is a lot of recent information including on virus-induced membrane fusion. The contributors of the chapters are all among the researchers who performed many of the pioneering studies in the field.

Buch. Zustand: Neu. Neuware - The Internet and the World Wide Web are deeply affecting the way things are traditionally done. E-commerce is changing businesses; the stock market is accessible to individuals; digitized journals, up-to-date databases, and newsgroups are changing the lives of researchers. Is it reasonable to think that learning will remain unaffected Nevertheless, universities, with their blend of teaching and research, have much to offer to those who wish to learn more than simple skills: judgment, initiative, and fair competition for research positions. Over the years, universities have acquired invaluable resources in the form of laboratories and libraries with specially trained staff. How can they evolve to take advantage of the many possibilities of the Internet and broadband communication Many institutions of higher education are trying to integrate new information and communications technologies into current curricula or to develop new learning paradigms for learning. Because it is still so early in the game they are eager to compare their efforts and results to the achievements of others and are willing to learn from them. The International Federation for Information Processing (IFIP) is a multi national federation of professional and technical organizations, founded in 1960 under the auspices of UNESCO, whose mission is to assist in the development, exploitation, and application of Information Technology for the benefit of all peoples. Given this scope of activity, IFIP seemed the appropriate body to give an international dimension to such a forum.
