Buch. Zustand: Neu. Neuware -After a year's successful operation, the European DENIS project is now a scientific reality and its close cousin 2MASS (USA) is about to come into operation. The observational and data reduction processes of both DENIS and 2MASS are fully described in this volume.Already the impact of DENIS is making itself felt in the astronomical community in areas of research as diverse as cosmology, the evolution of galaxies, the interstellar medium, the search for brown dwarfs, and stellar structure and evolution. The first routine results from DENIS and the preliminary results from the 2MASS prototype camera are discussed and compared with other surveys across the wavelength spectrum, both space- and ground-based, including the Digitized Sky Survey, ISO and ROSAT. 284 pp. Englisch.

Buch. Zustand: Neu. Neuware -Despite the significant progress, which has been made in developing of ceramic materials desired for engineering applications, their mass production is still not on expected level. Among the key factors hindering higher exploitation of these materials the problems in processing were identified. The processing comprises powder production, mixing techniques, forming, and sintering. All of them are equally important and all of them can introduce defects into the material. Besides improvement in processing, the properties of ceramic materials can be considerably improved by the creation of composites. Composites formed at micro or macro level are able to form more flaw-tolerant material. Considerable research activities, working on above mentioned phenomena are in progress at industrial laboratories as well as other research centres. This volume presents the contributions to the Advanced Research Workshop 'Engineering Ceramics '96' with 65 participants from 21 countries held on 12th - 15th May 1996 at Smolenice Castle, Slovakia, the conference site of Slovak Academy of Sciences. The book covers research activities on engineering ceramic materials and gives an overview with respect to recent developments. 444 pp. Englisch.

Buch. Zustand: Neu. Neuware -Foundational research focuses on the theory, but theories are to be related also to other theories, experiments, facts in their domains, data, and to their uses in applications, whether of prediction, control, or explanation. A theory is to be identified through its class of models, but not so narrowly as to disallow these roles. The language of science is to be studied separately, with special reference to the relations listed above, and to the consequent need for resources other than for theoretical description. Peculiar to the foundational level are questions of completeness (specifically in the representation of measurement), and of interpretation (a topic beset with confusions of truth and evidence, and with inappropriate metalinguistic abstraction).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 172 pp. Englisch.

Buch. Zustand: Neu. Neuware -In a way, the problem of the body in Husserl' s writings is relatively straightfo r ward: it is an exercise in faithful description and elaboration of a sense or mean ing, that of the 'lived body,' using the tools and methods of intentional analysis. What is to be described is nothing exotic, but a recognizable, familiar element of experience; further, it is not something limited to any special type of experience, but is ever-present, whether it is in the background or the center of attention. Thus the lived body is, in a way, the most mundane of topics in phenomenology, to be du1y noted as a matter of course--of course we should include the body in the analysis of lived space; of course the body is an element in the consciousness of other persons. Along with the obviousness of the task is the impression that, at least at the outset, the problem of the body does not appear to tax the resources of intentional analysis, forcing us to raise critical questions about the scope and limits of phenomenological philosophy. There is nothing extreme about the problem of the body-it demands neither that we discern structures of the end most interior of consciousness, as does the study of 'internal time conscious ness,' nor does it calion us to fix the sense of the normativity that constitutes the 'logic' of the world by grounding it in an absolute foundation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 172 pp. Englisch.

Buch. Zustand: Neu. Neuware -Corpus-based methods will be found at the heart of many language and speech processing systems. This book provides an in-depth introduction to these technologies through chapters describing basic statistical modeling techniques for language and speech, the use of Hidden Markov Models in continuous speech recognition, the development of dialogue systems, part-of-speech tagging and partial parsing, data-oriented parsing and n-gram language modeling.The book attempts to give both a clear overview of the main technologies used in language and speech processing, along with sufficient mathematics to understand the underlying principles. There is also an extensive bibliography to enable topics of interest to be pursued further. Overall, we believe that the book will give newcomers a solid introduction to the field and it will give existing practitioners a concise review of the principal technologies used in state-of-the-art language and speech processing systems.Corpus-Based Methods in Language and Speech Processing is an initiative of ELSNET, the European Network in Language and Speech. In its activities, ELSNET attaches great importance to the integration of language and speech, both in research and in education. The need for and the potential of this integration are well demonstrated by this publication.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 248 pp. Englisch.

Buch. Zustand: Neu. Neuware -Many books on optimization consider only finite dimensional spaces. This volume is unique in its emphasis: the first three chapters develop optimization in spaces without linear structure, and the analog of convex analysis is constructed for this case. Many new results have been proved specially for this publication. In the following chapters optimization in infinite topological and normed vector spaces is considered. The novelty consists in using the drop property for weak well-posedness of linear problems in Banach spaces and in a unified approach (by means of the Dolecki approximation) to necessary conditions of optimality. The method of reduction of constraints for sufficient conditions of optimality is presented. The book contains an introduction to non-differentiable and vector optimization.Audience: This volume will be of interest to mathematicians, engineers, and economists working in mathematical optimization.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 604 pp. Englisch.

Buch. Zustand: Neu. Neuware -Modeling Environmental Policy demonstrates the link between physical models of the environment and policy analysis in support of policy making. Each chapter addresses an environmental policy issue using a quantitative modeling approach. The volume addresses three general areas of environmental policy - non-point source pollution in the agricultural sector, pollution generated in the extractive industries, and transboundary pollutants from burning fossil fuels. The book concludes by discussing the modeling efforts and the use of mathematical models in general.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 216 pp. Englisch.

Buch. Zustand: Neu. Neuware -The 12th International Symposium on Plant Lipids was held at the University of Toronto, Canada, from July 7th to 12th, 1996. The conference was attended by over 200 scientists from university, government and corporate laboratories from 24 different countries. The topics covered in the symposium ranged from basic physiology, biochemistry and molecular biology of plant lipids to transformation and genetic engineering of crop plants. Oil seed plants were a particular focus of the symposium. There were 62 oral and 96 posters presentations. A special lecture in memory of the founder of this series of symposium, Terry Galliard, was presented by John Shanklin. This Proceedings Book has been dedicated to Grattan Roughan for his important contributions to our knowledge of plant lipid metabolism. This volume contains manuscripts submitted from most of the presentations at the symposium. It provides a useful summary of the major fields of plant lipid studies and our present state of knowledge. The papers are arranged in eight sections covering the major areas in the field of plant physiology, biochemistry and molecular biology of plant lipids. We would like to thank Valerie Imperial, Rajesh Khetarpal and Mary Williams for their invaluable help in organizing and running the meetings and excursions. John P. Williams, Mobashsher U. Khan and Nora W. Lem Toronto, Canada, October 1996 xvii DEDICATION This volume is dedicated to Grattan Roughan.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 442 pp. Englisch.

Buch. Zustand: Neu. Neuware -Can OUGHT be derived from IS This book presents an investigation of this time-honored problem by means of alethic-deontic predicate logic. New in this study is the leitmotif of relevance: is-ought inferences indeed exist, but they are all irrelevant in a precise logical sense. New proof techniques establish this result for very broad classes of logics. A profound philosophical analysis of is-ought bridge principles supplements the logical study. The final results imply incisive limitations for the justifiability of ethics as opposed to empirical science.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 348 pp. Englisch.

Buch. Zustand: Neu. Neuware -An attentive reader embarking on this book might wonder what 'the' economic transition to which the title refers might be. In this century almost all countries have gone through periods of economic transition; but which period of economic history can claim to embody the notion or to represent the era of 'the' transition Definitely, no country or group of countries has experienced anything comparable to the economic upheavals that the fall of communism has brought about in a large portion of the world in just three years (1989 to 1991). No other 'transition' to date has prompted more interest and more studies among economists, academics and policy-makers than has the transformation of centrally planned economies into market-based systems. It is this transformation that has come to define 'the' transition. Early in the transformation process (in November 1990), with the support of the Centre for Co-operation with the Economies in Transition (CCET), I launched a conference to examine the challenges faced by these countries. About six years have gone by and a new economic landscape has emerged in that part of the world. The difficulties in transforming these economies have exceeded all expectations, and economic performances have varied considerably across countries. The time has come, therefore, to make a first evaluation of progress and problems, with a view to extracting useful policy lessons to guide policy-makers in successfully completing the transition in the near future.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 628 pp. Englisch.

Buch. Zustand: Neu. Neuware -The Fifth International Workshop on Seeds was held at the University of Reading, UK, from 10 to 15 September, 1995. Some 230 seed scientists, from a wide range of disciplines (botanists, biochemists, ecologists, agriculturalists, foresters, and commercial seedsmen), from 31 countries (Europe, the Americas, and Asia) participated in the workshop. A large number of oral and poster presentations was made during the workshop and we are pleased to publish so many of them in these Proceedings. The papers herein are listed by the sessions in which they were presented but, as is often the case, many papers cover a broader range of topics than the session titles imply. For seed physiologists, ecologists, and technologists, this book collates much of the current research on seeds. 852 pp. Englisch.
