Taschenbuch. Etat : Neu. Neuware -Dieses Buch bietet eine theoretische Analyse verschiedener Alterssicherungssysteme; ein Thema, das infolge der demographischen Entwicklung weltweit an Interesse gewinnt. Im Vordergrund steht ein Vergleich von Umlage- und Kapitaldeckungsverfahren. Die breit angelegte Untersuchung behandelt ebenso Fragen wie 'staatliche versus private Alterssicherung'. Im Rahmen eines 'general equilibrium'-Ansatzes und unter Anstrebung größter Allgemeinheit (keine 'steady state'-Annahmen) werden Probleme gelöst, die lange als unentscheidbar galten. So kann mit Hilfe einfacher mathematischer Techniken gezeigt werden, daß ein Umlageverfahren eine definitive Verringerung des Kapitalbestandes bewirkt. Als wichtig wird indes nicht die Höhe des Kapitalbestandes, sondern die Effizienz des Alterssicherungssystems angesehen. Dieses bisher kaum erörterte Problem wird in den Vordergrund gerückt, der Verfasser argumentiert, daß sich auf diese Weise verschiedene Dispute wie die 'Feldstein-Kontroverse' auflösen und eindeutig entscheiden lassen.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Deutsch.

Taschenbuch. Etat : Neu. Neuware -Das Rationalisierungspotential der Zukunft liegt in der Montage. Daß diese Feststellung nach wie vor aktuell ist, zeigt sich schon allein in der Tatsache, daß die Montagekosten häufig immer noch den größten Teil der Herstellkosten ausmachen. Es ist deshalb heute für jeden Betriebs- und Fertigungsleiter eine unabdingbare Forderung, die Montage durch Rationalisierung, Automatisierung und Umstrukturierung kostengünstiger zu gestalten. Dies trifft vor allem auf die vielen mittelständischen Unternehmen zu, für die bisher aufgrund geringer Stückzahlen/Losgrößen und großer Variantenvielfalt eine durchgreifende Rationalisierung der Montage nicht möglich war. Die 19. Arbeitstagung des IPA wendet sich daher an Leiter in der Arbeitsvorbereitung, an Projekteure und alle diejenigen, die kompetente Antworten und praxisgerechte Lösungen zur flexiblen Montageautomatisierung suchen. Die Referenten der Tagung, die durchweg über eine langjährige Praxiserfahrung verfügen, behandeln in ihren Vorträgen u.a. folgende Themenbereiche: - Die informationstechnische Einbindung der Montage in die Fabrik der Zukunft - rechnerunterstützte Verfahren zur effizienten Planung moderner Montagesysteme - Montagegerechte Produktgestaltung: Voraussetzung für eine rationelle Montage - neue Möglichkeiten der Montageautomatisierung in mittelständischen Unternehmen - neue Einsatzfelder der Montageautomatisierung.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 460 pp. Deutsch.

Taschenbuch. Etat : Neu. Neuware -Das Buch enthält die Vorträge, die auf der Fachtagung 'Prozeßrechensysteme '88', Stuttgart, März 1988, gehalten wurden. Es gibt einen Überblick über den heutigen Stand der technischen Entwicklung auf den Gebieten der Automatisierungstechnik, der Prozeßleittechnik, sowie der Realzeit-Informations- und Kommunikationstechnik. Die Fachtagung 'Prozeßrechensysteme '88' stellt - als Weiterführung der Fachtagungen unter der früheren Bezeichnung 'Prozeßrechner' - die wichtigste und größte deutschsprachige Veranstaltung ihrer Art dar. Die in diesem Tagungsband zusammengefaßten Vorträge spiegeln den grundlegenden technischen Wandel wider, der sich in den letzten Jahren vollzogen hat und erfüllen die Zielsetzung der Fachtagung, aus den Gebieten der Automatisierungs-, Leit-, Informations- und Kommunikationstechnik zu berichten.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 816 pp. Deutsch.

Taschenbuch. Etat : Neu. Neuware -Die vorliegende Broschtire enthalt die z. T. erganzten Vortrage der 16. Fortbildungstagung fUr psychosomatische Geburtshilfe und Gynakologie yom 12. bis 14. Februar 1987 in Wtirzburg. Den Titel der yom Springer-Verlag nun schon in 5. Folge so hervorra gend herausgebrachten Schriftenreihe haben wir in 'Psychosoma tische Gynakologie und Geburtshilfe' geandert, wei I wir der Meinung waren, daB im Laufe der Jahre doch eine umfassende Darstellung der psychosomatischen Gynakologie und Geburts hilfe erfolgt ist. In erster Linie soil en durch diese Buchreihe Erfahrungen sowie Ergebnisse und nicht Probleme beschrieben werden. Auf der Wtirzburger Tagung wurde versucht, den Frauenarzten die anthropologische Medizin im Sinne V. E. v. Gebsattels und V. v. Weizsackers und die bionome Psychotherapie von 1. H. Schultz naher zu bringen. Beide Sichtweisen sind wenig geeignet, auf Tagungen vorgetragen oder diskutiert zu werden, denn sie erfordern doch vorgangig ein eingehendes Literaturstudium. So wurde den Teilnehmern als Anregung der Aufsatz V. E. v. Geb sattels 'Vom Sinn des arztlichen Handelns' aus dem Buche Imago hominis mitgegeben, der die Entstehung der anthropologi schen Medizin zu einem Seinsverstandnis des Menschen zu seinen kulturellen, religiosen, familiaren einfach zu seinem gesamten individuell moglichen Beztigen vermittelt. Der an diesem Thema Interessierte sei besonders auf die Arbeiten v. Weizsackers, die jetzt als Gesamtwerk erscheinen werden, und an die Prolegomena einer medizinischen Anthropologie V. E. v. Gebsat tels hingewiesen, in der er seine wesentlichen Arbeiten tiber den Geschlechtsleib, die psychasthenische Phobie, den personalen Faktor des Heilungsprozesses und seine Studien zur speziellen Psychopathologie zusammengefaBt hat.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Deutsch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The starting point of this Lecture Notes volume is Deligne's theorem about absolute Hodge cycles on abelian varieties. Its applications to the theory of motives with complex multiplication are systematically reviewed. In particular, algebraic relations between values of the gamma function, the so-called formula of Chowla and Selberg and its generalization and Shimura's monomial relations among periods of CM abelian varieties are all presented in a unified way, namely as the analytic reflections of arithmetic identities beetween Hecke characters, with gamma values corresponding to Jacobi sums. The last chapter contains a special case in which Deligne's theorem does not apply. 180 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is the proceedings volume of the symposium entitled 'Trends in Computer Algebra' held in Bad Neuenahr, May 19-21, 1987. Computer algebra is a very active research area on the borderline between mathematics and computer science, which will strongly influence mathematical and physical research in the near future. The intention of this symposium was to bring together specialists in computer algebra with researchers in related areas of mathematics and computer science as well as potential users of the developed tools and techniques in order to discuss present issues and future trends of this topic. The thirteen invited talks of the symposium were organized into the following groups: Languages and Systems, Symbolic Computations, Computing in Algebraic Structures, and Applications. 212 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -These proceedings of the first Quantum Probability meeting held in Oberwolfach is the fourth in a series begun with the 1982 meeting of Mondragone and continued in Heidelberg ('84) and in Leuven ('85). The main topics discussed were: quantum stochastic calculus, mathematical models of quantum noise and their applications to quantum optics, the quantum Feynman-Kac formula, quantum probability and models of quantum statistical mechanics, the notion of conditioning in quantum probability and related problems (dilations, quantum Markov processes), quantum central limit theorems. With the exception of Kümmerer's review article on Quantum Markov Processes, all contributions are original research papers. 380 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This seminar is a loose continuation of two previous conferences held in Lund (1982, 1983), mainly devoted to interpolation spaces, which resulted in the publication of the Lecture Notes in Mathematics Vol. 1070. This explains the bias towards that subject. The idea this time was, however, to bring together mathematicians also from other related areas of analysis. To emphasize the historical roots of the subject, the collection is preceded by a lecture on the life of Marcel Riesz. 456 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This text is an attempt to outline the basic facts concerning KekulEUR structures in benzenoid hydrocarbons: their history, applica tions and especially enumeration. We further pOint out the numerous and often quite remarkable connections between this topic and various parts of combinatorics and discrete mathematics. Our book is primarily aimed toward organic and theoretical chemists interested in the enume ration of Kekule structures of conjugated hydrocarbons as well as to scientists working in the field of mathematical and computational chemistry. The book may be of some relevance also to mathematicians wishing to learn about contemporary applications of combinatorics, graph theory and other branches of discrete mathematics. In 1985, when we decided to prepare these notes for publication, we expected to be able to give a complete account of all known combi natorial formulas for the number of Kekule structures of benzenoid hydrocarbons. This turned out to be a much more difficult task than we initially realized: only in 1986 some 60 new publications appeared dealing with the enumeration of Kekule structures in benzenoids and closely related topics. In any event, we believe that we have collec ted and systematized the essential part of the presently existing results. In addition to this we were delighted to see that the topics to which we have been devoted in the last few years nowadays form a rapidly expanding branch of mathematical chemistry which attracts the attention of a large number of researchers (both chemists and mathematicians). 372 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume represents the outcome of the International Conference on 'Extending Database Technology', held in Venice, Italy, in March 1988. It contains the major dimensions into which database technology is currently being pushed by the needs of new applications and pulled by the chances of novel developments in hardware and systems architecture. The two broad areas covered are: extended database semantics: data models and data types, databases and logic, complex objects, and expert system approaches to databases; and new architectures and increased database systems support: novel transaction models, data distribution and replication, database administration and access efficiency. Since an increasing amount of database research and development is done through international cooperation and within joint projects (ESPRIT, EUREKA, industrial cooperations), a substantial part of the book is dedicated to representing about a dozen advanced database projects on data- and knowledge-based systems and on distributed database applications by their aims, status, and results. 636 pp. Englisch.

In contrast to the preceding one this issue is written in English. There had been good reasons for this decision but there had been equally good arguments against it by some board members. We therefore consider this to be a trial. Being aware of the difficulties to prepare a book not in one's mother tongue the editors only made minor corrections of the authors' con tributions. Having published with the first proceedings an overview of the various fields of research on osteology in our country, the conference of the German Society for Osteology now deals with special subjects and so will this conference report. The main heading of this book being 'Generalized bone diseases'. One chapter will deal with new developments in the field of osteology and another presents unusual cases presented at the meeting. Our hopes are that the efforts of the German Society for Osteology, the local organizers and the editors will find some acknowledgement. Our thanks are due to the authors for their contributions as well as to the publishing house. 428 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Dieses Buch enthält die schriftlichen Ausarbeitungen von Vorträgen, die am 9. Oktober 1986 auf einem Workshop über Reason Maintenance gehalten worden sind. Der Begriff Begründungsverwaltung als Übersetzung von Reason Maintenance soll die Gleichzeitigkeit der Aspekte der Speicherung und Aufbewahrung der Begründungen und der Erhaltung der Gültigkeit von Aussagen auf Grund der gültigen Begründungen ausdrücken. Reason Maintenance ist eine Fortführung und Verallgemeinerung von Truth Maintenance. Truth-Maintenance-Systeme sind Programmsysteme, die Speicher von Aussagen realisieren, die weitgehend nur auf aussagenlogischer Ebene formalisiert sind. Sie verwalten Aussagenmengen und ihre Bewertungen. Annahmen und einfache Konsequenzen aus ihnen werden in einer Weise aufbewahrt, daß eine widerspruchsfreie Aussagenmenge zu jedem konkreten Zeitpunkt erkennbar ist. Die Technik, mit der dieses Ziel erreicht wird, besteht in der Repräsentation der Beziehungen zwischen den Aussagen und in der Aufbewahrung der Prämissen, Implikationen und Schlußregeln, die zur Ableitung einer bestimmten Aussage verwendet worden sind. Der Zweck dieser Systeme ist demnach Konsistenzerhaltung durch Begründungsverwaltung. Die vorliegenden Arbeiten repräsentieren den deutschen Wissensstand auf diesem Teilgebiet der Künstlichen Intelligenz unter Betonung des Ansatzes von de Kleer. Damit führt dieser Band den Leser an wesentliche aktuelle Forschungsergebnisse heran. 168 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Respiration is a unique topic among various subdisciplines of physiology. Physiolo gists and clinicians are now able to communicate quantitative functional properties of lung mechanics and gas exchange in the language of the engineer, physicist and mathematician. This is largely due to intensive and stimulating work during the last decades of brilliant minds in a handful of excellent schools in the international family of physiologists. Among these founders of respiratory physiology are a number of clinicians, and they have. taken significant ,part both in shaping the theoretical knowledge to clinical applicability and developing technical devices for diagnosis and therapy in pulmonology. However, the theory behind the evaluation of measure ments, and their interpretation in terms of clinical function tests, is so confusingly complex that the ordinary physician, not specifically trained in respiratory physiol ogy, finds himself unable to critically apply these techniques. We, therefore, need descriptions of respiratory physiology and of its clinical application presented in the language of the clinician. And that is what this book is meant to be. Written by an expert in electrical and biomedical engineering, and by an expert in intensive care medicine, this text constitutes an 'operational manual' of clinical respiratory physiology. It does not intend to be another textbook of basic respiratory physiology or pathophysiology. This book not only addresses practical clinicians, particularly those of intensive care medicine, by describing the essentials of clinically relevant respiratory knowledge. 188 pp. Englisch.

The editors and authors feel strongly that more standar dization in cancer therapy is needed on a worldwide basis. This, of course, is only possible if experts from all countries subscribe to a joint policy of making their treatment designs available to practising oncologists all over the world. Current Treatment of Cancer discusses all the equipment and methods now in use in cancer therapy. It covers all types of cancer, thus providing the reader with comprehensive infor mation on cancer management. In recent decades there has been a tremendous improve ment in the treatment of cancer, and there is hope for even fur ther success in this fight. We are convinced that this series will help us to make a concerted response to the challenge of can cer.
