Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is an extensively revised version of my textbook ' Yen esodot HaAlgebra HaLiniarit' (The Foundations of Linear Algebra) used at many universities in Israel. It is designed for a comprehensive one-year course in linear algebra (112 lecture hours) for mathematics majors. Therefore, I assume that the student already has a certain amount of mathematical background - including set theory, mathematical induction, basic analytic geometry, and elementary calculus - as wellas a modicum of mathematical sophistication. My intention is to provide not only a solid basis in the abstract theory of linear algebra, but also to provide examples of the application of this theory to other branches ofmathematics and computer science. Thus, for example, the introduction of finite fields is dictated by the needs of students studying algebraic coding theory as an immediate followup to their linear algebra studies. Many of the students studying linear algebra either are familiar with the care and feeding of computers before they begin their studies or are simultaneously en rolled in an introductory computer science course. Therefore, consideration of the more computational aspects of linear algebra - such as the solution of systems of linear equations and the calculation of eigenvalues - is delayed until all students are assumed able to write computer programs for this purpose. Beginning with Chap ter VII, there is an implicit assumption that the student has access to a personal computer and knows how to use it. 248 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -REFLECTIONS ON SPACETIME - FOUNDATIONS, PHILOSOPHY AND HISTORY During the academic year 1992/93, an interdisciplinary research group constituted itself at the Zentrum fUr interdisziplinare Forschung (ZiF) in Bielefeld, Germany, under the title 'Semantical Aspects of Spacetime Theories', in which philosophers and physicists worked on topics in the interpretation and history of relativity theory. The present issue consists of contributions resulting from material presented and discussed in the group during the course of that year. The scope of the papers ranges from rather specialised issues arising from general relativity such as the problem of referential indeterminacy, to foundational questions regarding spacetime in the work of Carnap, Weyl and Hilbert. It is well known that the General Theory of Relativity (GTR) admits spacetime models which are 'exotic' in the sense that observers could travel into their own past. This poses a number of problems for the physical interpretation of GTR which are also relevant in the philosophy of spacetime. It is not enough to exclude these exotic models simply by stating that we live in a non-exotic universe, because it might be possible to 'operate time machines' by actively changing the topology of the future part of spacetime. In his contribution, Earman first reviews the attempts of physicists to prove 'chronology protection theorems' (CPTs) which exclude the operation of time machines under reasonable assumptions. 172 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume represents a contribution to the philosophy of economics with a distinctive point of view -- the contributors have selected particular areas of economics and have probed these areas for the philosophical and methodological issues that they raise. The primary essays are written by philosophers concentrating on philosophical issues that arise at the level of the everyday theoretical practice of working economists. Commentary essays are provided by working economists responding to the philosophical arguments from the standpoint of their own disciplines. The volume thus represents something of an `experiment' in the philosophy of science, striving as it does to explore methodological issues across two research communities. The purpose of the volume is very specific: to stimulate a discussion of the epistemology and methodology of economics that works at the level of detail of existing `best practice' in economics today. The contributors have designed their contributions to stimulate productive conversation between philosophers and economists on topics in the methodology of economics. 300 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A comprehensive review of current knowledge of the deep-water fishes of the North Atlantic and their exploitation. Individual countries and research institutions have carried out their own investigations and surveys in the past, but these results have rarely been coordinated, nor has there been a proper sharing of results and data. But there is a need to assess the total size of the deep-water stocks and the extent to which they can safely be exploited. The book also contains a number of papers describing present and past research and the present exploitation of resources, together with papers on the technical problems encountered in capturing and processing these fishes. An assessment of the requirements for future research is presented. 440 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Environmental considerations are playing an increasingly important role in determining management strategies for soil and land. Many important environmental issues involve aspects of the biology of soil, and these issues cannot be considered satisfactorily in isolation from a general understanding of soil biology as a whole. This is the second edition of a book first published in 1989 and now thoroughly rewritten to focus on soil ecology and environmental issues. The first part of the book provides an introduction to soils, its inhabitants, and their activities. The second part covers the influence of man on the natural cycles of soil. Topics such as acid rain and nitrogen fertilizers are considered alongside pesticides and genetically modified organisms. A new final chapter has been added which considers how, as we move towards the next millennium, we can apply the concept of sustainability to issues such as global climate change and farming systems. The book is directed at advanced undergraduate and immediate postgraduate students in environmental science and soil ecology, with students of physical geography and earth sciences as an important secondary market. 164 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Many books have been written about Wittgenstein's philosophy, but this collection of articles on Wittgenstein and education is the first study in book form in this area. There have been several articles in scholarly education journals, but the special cachet of this collection is that the contributors come from six countries. The collection has been edited by Paul Smeyers and Jim Marshall, philosophers of education who live in Belgium and New Zealand, respectively. Each of the chapters represents an original study of Wittgenstein, commissioned by the editors from colleagues they know to have written well on Wittgenstein and the implications of his ideas for education. Audience: Teachers, students and academics in the field of philosophy and education. Especially interesting to advanced students in these areas. 256 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -IAU Symposium No. 167 brought together researchers who use CCDs and arrays, designers and manufacturers of CCDs and Array Mosaics and those who write the software to control these devices and to reduce the large amounts of data contained in each frame. At the meeting such topics as plans for applying the new technology to the new large telescopes that have been built recently and those planned in the near future, new developments in infrared arrays, advances and concerns with the use of CCDs in photometry and spectroscopy and the creation of large mosaics in photometry and spectroscopy and the creation of large mosaics of chips which allow larger areas of the sky to be covered in a single frame were discussed. There were sessions devoted to the following topics: New Developments in CCD Technology; New Developments in IR Detector Arrays; Direct Imaging with CCDs and Other Arrays; Spectroscopy with CCDs and Other Arrays; and Large Field Imaging with Array Mosaics. Scientific results of studies made with this technology were covered in the poster sessions. CCD and Array Detectors have become the detectors of choice at all the world's optical observatories. Such instruments on small university and college telescopes have turned these telescopes into instruments that can now do observations which in the past were done only on the largest telescopes. CCDs and Arrays are known as `the people's detector' because of their ability to turn small telescopes into true research instruments. On large telescopes observations can be made of extremely faint and crowded objects that were impossible to observe before the advent of CCD and Array technology. The proceedings of this meeting will be useful to all those who are interested in the design, manufacture and use of CCDs and Arrays for astronomical observations. 420 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In Consequentialism Reconsidered, Carlson strives to find a plausible formulation of the structural part of consequentialism. Key notions are analyzed, such as outcomes, alternatives and performability. Carlson argues that consequentialism should be understood as a maximizing rather than a satisficing theory, and as temporally neutral rather than future oriented. He also shows that certain moral theories cannot be reformulated as consequentialist theories. The relevant alternatives for an agent in a situation are taken to comprise all actions that they can perform in the situation. The defense of this idea necessitates certain modifications to the standard consequentialist criteria of obligatoriness, rightness and wrongness. The problem of whether agents should adapt their actions to their own future actions is also addressed. Further, a conditional analysis of performability is suggested, and it is argued that particular actions should in this connection be regarded as `abstract' rather than `concrete'. The final chapter sketches a consequentialist theory for collective agents. 188 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Human knowing is examined as it emerges from classical empirical psychology, with its ramifications into language, computing, science, and scholarship. While the discussion takes empirical support from a wide range, claims for the significance of logic and rules are challenged throughout. Highlights of the discussion: knowing is a matter of habits or dispositions that guide the person's stream of consciousness; rules of language have no significance in language production and understanding, being descriptions of linguistic styles; statements that may be true or false enter into ordinary linguistic activity, not as elements of messages, but merely as summaries of situations, with a view to action; in computer programming the significance of logic, proof, and formalized description, is incidental and subject to the programmer's personality; analysis of computer modelling of the mental activity shows that in describing human knowing the computer is irrelevant; in accounting for the scholarly/scientific activity, logic and rules are impotent; a novel theory: scholarship and science have coherent descriptions as their core. The discussion addresses questions that are basic to advanced applications of computers and to students of language and science. 384 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The so-called reaction path (RP) with respect to the potential energy or the Gibbs energy ('free enthalpy') is one of the most fundamental concepts in chemistry. It significantly helps to display and visualize the results of the complex microscopic processes forming a chemical reaction. This concept is an implicit component of conventional transition state theory (TST). The model of the reaction path and the TST form a qualitative framework which provides chemists with a better understanding of chemical reactions and stirs their imagination. However, an exact calculation of the RP and its neighbourhood becomes important when the RP is used as a tool for a detailed exploring of reaction mechanisms and particularly when it is used as a basis for reaction rate theories above and beyond TST. The RP is a theoretical instrument that now forms the 'theoretical heart' of 'direct dynamics'. It is particularly useful for the interpretation of reactions in common chemical systems. A suitable definition of the RP of potential energy surfaces is necessary to ensure that the reaction theories based on it will possess sufficiently high quality. Thus, we have to consider three important fields of research: - Analysis of potential energy surfaces and the definition and best calculation of the RPs or - at least - of a number of selected and chemically interesting points on it. - The further development of concrete vers ions of reaction theory beyond TST which are applicable for common chemical systems using the RP concept.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 312 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Since the first pacemaker implantation in October 1958 by Senning and Elmqvist in Sweden, cardiac pacing for bradycardia has become a well-established therapy. The impressive growth of clinical experience and the rapid development of pacemaker devices have greatly contributed to this situation. The electrical therapy appears to be so easy that insertion of the lead and its connection to the pacemaker generator requires little effort, skill or insight. However, after implantation a patient's condition seldom remains stable, which requires a flexible pacing program to cover all new cardiac events, and broad insight from clinician and technical colleagues. The Pacemaker Clinic of the 90's teaches anatomical and electrophysiological aspects of pacing, supports the prevention of complications, and points to new developments in the field. Apart from classical indications for cardiac pacing, the book discusses the validity of the latest indications, supporting the cardiologist and the associated professional in selecting the appropriate pacing mode and pacemaker follow-up in individual patients. The Pacemaker Clinic of the 90's will be a helpful companion for years to come. 292 pp. Englisch.

Since thattime, there have been two major theoretical developments that bear directly on the analysesoriginallydevelopedin the dissertation. These aretheinceptionof the 'Minimalist Program' of Chomsky (1992, 1993), and the recent 'Antisymmetry' proposals presented in Kayne (1993). Taken in conjunction with the many criticisms and suggestions ofreviewers, these proposals have prompted significant revisions ofthe earlier work:. Every chapter has been substantially revised, the introductory chapter has been replaced, and Chapters 2, 3 and 5 offer completely new analyses of the originalmaterial. The book comprises a set of theoretical studies of aspects of Modern Irish syntax. I have tried to present a coherent and consistent treatmentof the Irishfacts; abookin which the particularsofIrish syntax- which are in many cases quiteeccentric from an Englishperspective- are shown to inform more general theoreticalissues. I also hope to have offered to the non-Celticist a reasonably complete overview of the major syntactic structures ofIrish, with some indication and analysisofthe more importantdialectdifferences. 392 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Significant experimental work is devoted to the preparation of one and zero dimensional semiconductor structures in view of future electronic and optical devices which involve quantum effects. The aim is good control in the realisation of nanometer structures both in vertical and lateral direction. Conventional processing techniques based on lithography face inherent problems such as limited resolution and surface defects caused by reactive ion etching. During the last few years several research groups started working on direct syntheses of semiconductor nanostructures by combining epitaxial growth techniques such as molecular beam epitaxy and chemical vapour deposition with pre patterning of the substrate wafers. Another idea is based on island formation in strained layer heteroepitaxy. Zero and one dimensional structures with dimensions down to a few atomic distances have been realised this way. An important point is that the size of the quantum structures is controlled within the epitaxial deposition in a self-adjusting process. The main subjects of the book are: Theoretical aspects of epitaxial growth, selfassembling nanostructures and cluster formation, epitaxial growth in tilted and non-(001) surfaces, cleaved edge overgrowth, nanostructure growth on patterned silicon substrates, nanostructures prepared by selective area epitaxy or growth on patterned substrates, in-situ etching and device applications based on epitaxial regrowth on patterned substrates. The experimental work mainly concentrated on GaAs/A1GaAs, GaAs/InGaAs, InGaP/InP and Si/SiGe based semiconductor heterostructures. Growth related problems received special attention. The different concepts for preparation of low dimensional structures are presented to allow direct comparison and to identify new concepts for future research work. 402 pp. Englisch.
