Taschenbuch. Etat : Neu. Neuware -Europe faces a challenge: how to apply information and communication technologies to health care. One problem is the widening gap between the expectations of citizens and the limited resources available to provide health services. It is here that advanced technology can serve as an important tool to find innovative and more efficient ways of delivering health services. This book reports the summary of a study performed under contract by a team of consultants for Directorate-General XIII of the Commission of the European Communities. It analyses the key factors governing the evolution of advanced information systems for health care and medicine in Europe and provides guidelines for placing current and future work within the framework of the Community research and development programmes.

Taschenbuch. Etat : Neu. Neuware -Out of the multitude of physical processes whose mechanisms depend on the interaction between the atmosphere and a lake, only those have been selected for discussion in this book which are inevitable in the mathematical modeling of lake hydrology and the microclimates, i.e., the meteorological regime over lakes and surrounding land. There are many reasons for a combined consideration of tile hydrological and meteorological aspects. First of all, they are essentially similar from a fluid mechanical point of view. Thus, the same phenomenon, viz., the turbulent plan etary boundary layer, is represented in lakes as the upper well-mixed water layer and in the atmosphere as the lower air layer directly influenced by thermal and dynamical action of the underlying surface. Processes at the air/water interface are equally important in energy transfer in both media. And finally, dynamical and thermal interaction between the adjoining atmospheric and lacustrine bound ary layers appears to be even stronger than between the upper and deep-water layers of a lake.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 152 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -Die Gliederung nach diagnostischen Situationen und nicht nach Symptomen oder Krankheiten stellt die Besonderheit dieses Buches dar. In dieser Neuauflage werden die diagnostischen Überlegungen noch ausführlicher beschrieben. Neugewonnene Erkenntnisse, die sich im klinischen Alltag bewährt haben, sind an vielen Stellen eingearbeitet. Aus der Anamnese und der körperlichen Untersuchung entstehen Hypothesen, aus denen sich Untersuchungsverfahren mit ganz konkreten Erwartungen ableiten lassen. Diagnostische Irrtümer beruhen häufig nicht auf einem Mangel an Wissen, sondern an 'unscharfem Denken'. Entsprechend will das Buch dem Leser nicht nur Kenntnisse, sondern auch eine diagnostische Denkweise nahebringen, in der man parallel möglichst viele Optionen gegeneinander abwägt.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Deutsch.

Taschenbuch. Etat : Neu. Neuware -Das vorliegende Buch behandelt das Konzept des Least-Cost Planning ('Minimalkosten-Planung'). Hierbei handelt es sich um ein auf allen Stufen der Energiewirtschaft anwendbares systemanalytisches Konzept der Planung, der (Kosten-)Optimierung und der Umsetzung von Investitionsalternativen des Angebots oder der Einsparung von Energie. Insbesondere wird die Frage untersucht, inwieweit positive Erfahrungen aus den USA mit Einsparungsprogrammen nach Least-Cost Planning (LCP) auf die unterschiedlichen energiewirtschaftlichen bzw. -rechtlichen Verhältnisse in der Bundesrepublik übertragen werden können. Es wird gezeigt, daß Least-Cost Planning bei der Unternehmensplanung von Energieversorgungsunternehmen, bei der Erstellung und Umsetzung von örtlichen und regionalen Energiekonzepten sowie insbesondere auch für die Theorie und Praxis der öffentlichen Energieaufsicht in der Bundesrepublik einen zentralen Stellenwert einnehmen sollte.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 456 pp. Deutsch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -1.1 Some characteristics of the floating exchange rate system The flexible exchange rate system has functioned far less satisfactorily than many anticipated in 1973, when the major industrialized countries decided to let their currencies float. The dominant currencies' exchange rates have fluctuated more 1 than expected. These fluctuations concern both short-term movement- intraday fluctuations and movements during a week or a month - and long term changes that last for more than a year. Daily percentage changes of one percent are not unusual for the recent float (see MacDonald, 1988, p.8). However, the release of new information can give rise to much larger changes. For example in August 1987 'the dollar moved down 6 percent in two days based on the July trade figures' (Glynn, 1988, p. 36). For the period 1973-1985 MacDonald (1988, p.10) presents minimum and maximum monthly percentage exchange rate changes. These figures clearly illustrate the magnitude of the volatility and also show that the volatility has not diminished as the experience 2 with floating has increased. In addition to this volatility, exchange rates are also characterized by misalignment: 'persistent departure of the exchange rate from its long-run equilibrium' (Williamson, 1983, p.l3). Although the measure of misalignment depends upon the exact definition of the exchange rate's long-run equilibrium, there is a widespread feeling that during the greater part of the 1970s the dollar was undervalued, whereas it was overvalued during the first half of the 1980s. 284 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is a collection of 22 papers presented at the International Workshop on Information Processing in Autonomous Mobile Robots, held in Munich (Germany) in March 1991. Autonomous mobile robot technologies are generating significant interest because of their potential capabilities for future applications on the plant floor as weil as in the service industry. Autonomous robots may navigate around factories and laboratories, hospitals, office-buildings, airports or sirnilar public and sernipublic places. They may deliver equipment, coilect garbage and perform other such tasks. One of the major challenges for the field of autonomous mobile robot research is to develop robust and real-time systerns for perception and understanding of complicated real environments as weil as for intelligent decision-making with respect to proper actions. This Workshop was set up to stimulate discussion and the exchangement of new ideas on various aspects of autonomous mobile robot methodologies and applications. The main focal points of the Workshop program were sensing and perception, navigation and control, knowledge bases and computer architechtures as weil as various applications. The papers are prepared by leading experts in theses areas from Europe, Japan, the United States and by researchers involved in the interdisciplinary research project on 'Information Processing in Autonomous Mobile Robots (Sonderforschungsbereich 331)' at the Technische Universität München. 368 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Software development environments are integrated sets of tools, techniques and processes that assist in the sys- tematic development of software products. They are intended to support all phases of the software development cycle: requirements definition, design, implementation, test, and maintenance. These Computer Aided Software Engineering (CASE) tools typically make use of graphic manipulation facilities and rely on some form of development database to exchange various types of design objects between tools. Facilitated by the availability of powerful workstations, implementations of these technologies are now within reach of every software developer. This volume presents the proceedings of a symposium organized by the GI (Gesellschaft für Informatik), the GMD (Gesellschaft für Mathematik und Datenverarbeitung) and ESEC (European Software Engineering Conferences). The symposium brought together application development managers and top specialists involved in the selection and introduction of software development tools, leading developers of such tools and well known authorities from the research community. The proceedings contain first-hand information on practical experiences and requirements, development directions and strategies, and key research issues and results. 300 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Methods for the algebraic specification of abstract data types were proposed in the early 1970s in the USA and Canada and became a major research issue in Europe shortly afterwards. Since then the algebraic approach has come to play a central role in research on formal specification and development, as its range of applications was extended to the specification of complete software systems, to the formal description of the program development process, and to the uniform definition of syntax and semantics of programming languages. Today this approach extends beyond just software to the development of integrated hardware and software systems. These flourishing activities in the area of algebraic specifications have led to an abundance of approaches, theories and concepts, which have universal algebra, category theory and logic as a common mathematical basis. This volume is an annotated bibliography which provides an up-to-date overview of past and present work on algebraic specification. No attempt is made to provide a coherent introduction to the topic for beginners; the intention is rather to provide a guide to the current literature for researchers in algebraic specification and neighboring fields. Some indications of how the different approaches are related are included, together with some ideas concerning possible future directions. 112 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume presents the proceedings of a workshop on parallel database systems organized by the PRISMA (Parallel Inference and Storage Machine) project. The invited contributions by internationally recognized experts give a thorough survey of several aspects of parallel database systems. The second part of the volume gives an in-depth overview of the PRISMA system. This system is based on a parallel machine, where the individual processors each have their own local memory and communicate with each other over a packet-switched network. On this machine a parallel object-oriented programming language, POOL-X, has been implemented, which provides dedicated support for database systems as well as general facilities for parallel programming. The POOL-X system then serves as a platform for a complete relational main-memory database management system, which uses the parallelism of the machine to speed up significantly the execution of database queries. The presentation of the PRISMA system, together with the invited papers, gives a broad overview of the state of the art in parallel database systems. 448 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Currently, the field of information systems technology is rapidly extending into several dimensions. There is the semantic dimension (including object orientation, data deduction and extended knowledge representation schemes), there is improved systems integration, and there are new tools. All these extensions aim to provide semantically richer and better engineered information systems that allow for more adequate and complete representations and thus extend the effective use of database technology to a wider class of applications. Database researchers and developers, whether they are committed to application or to system construction, are convinced that next-generation information system technology will be heavily determined by a handful of new concepts that they have to understand and work out in detail now. This volume concentrates on the following topics: - Extended data types and data models, database programming languages; - Rule-based data deduction, expert systems, knowledge bases; - Object orientation and semantic data modelling; - DB application development, methodologies and tools; - Interface technology, parallelism, interoperability, .; - New database applications. 468 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this monograph the author presents a thorough computational geometry approach to handling theoretical and practical problems arising from numerically controlled pocket machining. The approach unifies two scientific disciplines: computational geometry and mechanical engineering. Topics of practical importance that are dealt with include the selection of tool sizes, the determination of tool paths, and the optimization of tool paths. Full details of the algorithms are given from a practical point of view, including information on implementation issues. This practice-minded approach is embedded in a rigorous theoretical framework enabling concise statement of definitions and proof of the correctness and efficiency of the algorithms. In particular, the construction of Voronoi diagrams and their use for offset calculations are investigated in great detail. Based on Voronoi diagrams, a graph-like structure is introduced that serves as a high-level abstraction of the pocket geometry and provides the basis for algorithmically performing shape interrogation and path planning tasks. Finally, the efficiency and robustness of the approach is illustrated with figures showing pocketing examples that have been processed by the author's own implementation. 196 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -During the last decade scientists in both basic and clinical research have renew ed their interest in the potential role of thrombolytic therapy in the treatment of acute ischemic stroke. The reevaluation of this approach was kindled by our growing knowledge of the pathogenesis of thrombotic and embolic stroke and by the development of new thrombolytic agents. With no proven therapy for acute ischemic stroke available, the potential value of early pharmacologic recanalization of occluded vessels in the management of acute stroke patients - an approach that has been supported by animal experiments and a limited number of uncontrolled clinical pilot studies - is again under scrutiny. A sym posium on 'Thrombolysis in Acute Cerebral Ischemia' was held in Heidel berg, Germany, in May 1990 to summarize and discuss the pathophysiological background for thrombolysis in acute ischemic stroke and the recent ex perimental and clinical experience with the new generation of thrombolytic agents. The editors are fortunate to be able to include authoritative manuscripts from almost all the speakers at the symposium. These include reports of work by the most active investigators in this challenging field. The editors wish to express their gratitude to all the contributors for the additional work they have undertaken. Additionally, we would like to thank Springer-Verlag, Heidelberg, for its generous assistance in the preparation and rapid publication of this volume. Heidelberg, August 1990 WERNER HACKE GREGORY J.

Neuware -The large aggregates in the economy - consumption, investment, production of the domestic and the international sectors, international capital flows, financial accumulation and indebtedness - are analysed in this book as problems in time-optimisation for enterprises and households. The effects of fiscal and monetary policies along with exchange-rate variation are examined, and their simultaneous use for stabilizing demand are found to be necessary. All household decisions on consumptions, savings, and financial disposition are conditioned by uncertainty, and similarly for firms, who make more complex simultaneous decisions on production, real investment, financing, and market strategy. The marginal efficiency-of-investment function derived from these decisions is fundamentally different from the marginal productivity of capital in the neoclassical sense. An economy which grows through the accumulation of capital, increase in labor supply, and technological progress is the framework in which all of these variables move. This codetermines the allocation of factors between domestic and international production, and the development of foreign trade. The growth both of the public debt and of international investment are treated in depth.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

Neuware -This volume contains the proceedings ofthe 4th Refinement Workshop which was organised by the British Computer Society specialist group in Formal Aspects of Computing Science and held in Wolfson College, Cambridge, on 9-11 January, 1991. The term refinement embraces the theory and practice of using formal methods for specifying and implementing hardware and software. Most of the achievements to date in the field have been in developing the theoretical framework for mathematical approaches to programming, and on the practical side in formally specifying software, while more recently we have seen the development of practical approaches to deriving programs from their speCifications. The workshop gives a fair picture of the state of the art: it presents new theories for reasoning about software and hardware and case studies in applying known theory to interesting small-and medium-scale problems. We hope the book will be Of interest both to researchers in formal methods, and to software engineers in industry who want to keep abreast of possible applications of formal methods in industry. The programme consisted both of invited talks and refereed papers. The invited speakers were Ib S0rensen, Jean-Raymond Abrial, Donald MacKenzie, Ralph Back, Robert Milne, Mike Read, Mike Gordon, and Robert Worden who gave the introductory talk. This is the first refinement workshop that solicited papers for refereeing, and despite a rather late call for papers the response was excellent.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 492 pp. Englisch.

Neuware -This is the first international conference aimed at bringing the distributed database and distributed AI (DAD experts together, from both academia and industry, in order to discuss the issues of the next generation of knowledge based systems, namely Cooperating Knowledge Based Systems or CKBS for short. As the area of CKBS is new, we intended it to be an ideas conference - a conference where interesting new ideas, rather than results from completed projects, are explored, discussed, and debated. The conference was organised by the DAKE Centre. This is an interdisciplinary centre at the University of Keele for research and development in Data and Knowledge Engineering (DAKE). The Centre draws most of its strength from the Department of Computer Science which also provides administrative support for the activities of the Centre, although its membership is spread over several departments. The Centre has three main streams of research activities, namely: Large Knowledge Bases Software Engineering Neural Networks The Large Knowledge Base group, which provided the focus for this conference, is active in a number of research areas relating to data and knowledge bases, spanning from distributed databases to cooperations among data and knowledge bases. The current research topics include integration of data and knowledge bases and coopera ting knowledge based systems, with several major projects in the latter (see the entries under the Poster Session given below).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 344 pp. Englisch.

The reevaluation of this approach was kindled by our growing knowledge of the pathogenesis of thrombotic and embolic stroke and by the development of new thrombolytic agents. With no proven therapy for acute ischemic stroke available, the potential value of early pharmacologic recanalization of occluded vessels in the management of acute stroke patients - an approach that has been supported by animal experiments and a limited number of uncontrolled clinical pilot studies - is again under scrutiny. A sym posium on 'Thrombolysis in Acute Cerebral Ischemia' was held in Heidel berg, Germany, in May 1990 to summarize and discuss the pathophysiological background for thrombolysis in acute ischemic stroke and the recent ex perimental and clinical experience with the new generation of thrombolytic agents. The editors are fortunate to be able to include authoritative manuscripts from almost all the speakers at the symposium. These include reports of work by the most active investigators in this challenging field. The editors wish to express their gratitude to all the contributors for the additional work they have undertaken. Additionally, we would like to thank Springer-Verlag, Heidelberg, for its generous assistance in the preparation and rapid publication of this volume. Heidelberg, August 1990 WERNER HACKE GREGORY J.
