Buch. Zustand: Neu. Neuware - This volume covers many aspects of multimedia and communications security, from national security policies to file server architectures, from hypertext documents to specialized cryptographic algorithms. It provides the interested reader with a spectrum of up-to-the-minute knowledge on the topics covered.

Buch. Zustand: Neu. Neuware - To a large extent, our lives on this earth depend on systems that operate auto matically. Manysuchsystems can be found in nature and others are man made. These systems can be biological, electrical, mechanical, chemical, or ecological, to namejust a few categories. Our human body is full ofsystems whose conti nued automatic operation is vital for our existence. On a daily basis we come in contact with man made systems whose automatic operation ensures increa sed productivity, promotes economic development and improves the quality of life. A primary component that is responsible for the automatic operation of a system is a device or mechanism called the controller. In man made systems one must first design and then implement such a controller either as a piece of hardware or as software code in a computer. The safe and efficient automatic operation of such systems is testimony to the success of control theorists and practitioners over the years. This book presents new methods {or controller design. The process ofdeveloping a controller or control strategy can be dramatically improved if one can generate an appropriate dynamic model for the system under consideration. Robust control design deals with the question of how to develop such controllers for system models with uncertainty. In many cases dynamic models can be expressed in terms oflinear, time invariant differential equations or transfer functions.

Buch. Zustand: Neu. Neuware - Co-Synthesis of Hardware and Software for Digital Embedded Systems, with a Foreword written by Giovanni De Micheli, presents techniques that are useful in building complex embedded systems. These techniques provide a competitive advantage over purely hardware or software implementations of time-constrained embedded systems. Recent advances in chip-level synthesis have made it possible to synthesize application-specific circuits under strict timing constraints. This work advances the state of the art by formulating the problem of system synthesis using both application-specific as well as reprogrammable components, such as off-the-shelf processors. Timing constraints are used to determine what part of the system functionality must be delegated to dedicated application-specific hardware while the rest is delegated to software that runs on the processor. This co-synthesis of hardware and software from behavioral specifications makes it possible to realize real-time embedded systems using off-the-shelf parts and a relatively small amount of application-specific circuitry that can be mapped to semi-custom VLSI such as gate arrays. The ability to perform detailed analysis of timing performance provides the opportunity of improving the system definition by creating better phototypes. Co-Synthesis of Hardware and Software for Digital Embedded Systems is of interest to CAD researchers and developers who want to branch off into the expanding field of hardware/software co-design, as well as to digital system designers who are interested in the present power and limitations of CAD techniques and their likely evolution.

Buch. Zustand: Neu. Neuware - The communication of information is a crucial point in the development of our future way of life. We are living more and more in an information society. Perhaps the more obvious applications are those devoted to distributed cooperative multimedia systems. In both industry and academia, people are involved in such projects. HPN'95 is an international forum where both communities can find a place for dialogues and interchanges. The conference is targeted to the new mechanisms, protocols, services and architectures derived from the need of emerging applications, as well as from the requirements of new communication environments. This workshop belongs to the series started in 1987 in Aachen (Germany), followed by Liege (Belgium) in 1988, Berlin (Germany) in 1991, Liege (Belgium) again in 1992 and Grenoble (France) in 1994. HPN'95 is the sixth event of the series sponsored by IFIP WG 6.4 and will be held at the Arxiduc Lluis Salvador building on the campus of the University of the Balearic Islands in Palma de Mallorca (Spain) from September 13 to 15.

Buch. Zustand: Neu. Neuware - This is a compilation of papers presented at the Information System Concepts conference in Marburg, Germany. The special focus is consolidation and harmonisation of the numerous and widely diverging views in the field of information systems. This issue has become a hot topic, as many leading information system researchers and practitioners come to realise the importance of better communication among the members of the information systems community, and of a better scientific foundation of this rapidly evolving field.

Buch. Zustand: Neu. Neuware - Technical and Biological Components of Marrow Transplantation presents up to date information on the scientific and technological advances that will extend and improve the clinical application of bone marrow transplantation. The book includes the latest information on chronic myeloid leukemia and thalassemia; advances in supportive care: cytokines and progenitor expansion; and cord stem cell technology. Soon more of patients will receive marrow transplants as part of the therapy for solid tumors and metabolic disease than for the treatment of hematologic disease. The contributors to this volume describe some of these applications, hinting at yet further, exciting possibilities.

Buch. Zustand: Neu. Neuware - Temporal databases have been an active research topic for at least fifteen years. During this time, several dozen temporal query languages have been proposed. Many within the temporal database research community perceived that the time had come to consolidate approaches to temporal data models and calculus based query languages, to achieve a consensus query language and associated data model upon which future research can be based. While there were many query language proposals, with a diversity of language and modeling constructs, common themes kept resurfacing. However, the community was quite frag mented, with each research project being based on a particular and different set of assumptions and approaches. Often these assumptions were not germane to the research per se, but were made simply because the research required a data model or query language with certain characteristics, with the partic ular one chosen rather arbitrarily. It would be better in such circumstances for research projects to choose the same language. Unfortunately, no existing language had attracted a following large enough to become the one of choice. In April, 1992 Richard Snodgrass circulated a white paper that proposed that a temporal extension to SQL be produced by the research community. Shortly thereafter, the temporal database community organized the 'ARPA/NSF In ternational Workshop on an Infrastructure for Temporal Databases,' which was held in Arlington, TX, in June, 1993.
