Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is a textbook written for use in a graduate-level course for students of mechanics and engineering science. It is designed to cover the essential features of modern variational methods and to demonstrate how a number of basic mathematical concepts can be used to produce a unified theory of variational mechanics. As prerequisite to using this text, we assume that the student is equipped with an introductory course in functional analysis at a level roughly equal to that covered, for example, in Kolmogorov and Fomin (Functional Analysis, Vol. I, Graylock, Rochester, 1957) and possibly a graduate-level course in continuum mechanics. Numerous references to supplementary material are listed throughout the book. We are indebted to Professor Jim Douglas of the University of Chicago, who read an earlier version of the manuscript and whose detailed suggestions were extremely helpful in preparing the final draft. We also gratefully acknowedge that much of our own research work on va ri at i ona 1 theory was supported by the U. S. Ai r Force Offi ce of Scientific Research. We are indebted to Mr. Ming-Goei Sheu for help in proofreading. Finally, we wish to express thanks to Mrs. Marilyn Gude for her excellent and painstaking job of typing the manuscript. This revised edition contains only minor revisions of the first. Some misprints and errors have been corrected, and some sections were deleted, which were felt to be out of date. 328 pp. Englisch.

Neuware -These notes are an elaboration of the first part of a course on foliations which I have given at Strasbourg in 1976 and at Tunis in 1977. They are concerned mostly with dynamical sys tems in dimensions one and two, in particular with a view to their applications to foliated manifolds. An important chapter, however, is missing, which would have been dealing with structural stability. The publication of the French edition was re alized by-the efforts of the secretariat and the printing office of the Department of Mathematics of Strasbourg. I am deeply grateful to all those who contributed, in particular to Mme. Lambert for typing the manuscript, and to Messrs. Bodo and Christ for its reproduction. Strasbourg, January 1979.

Nevertheless, it still plays a leading role in mathematics at a higher level. Its central role in the history of mathematics has never been disputed. It is important, therefore, to introduce some geometry into university syllabuses. There are several ways of doing this, it can be incorporated into existing courses that are primarily devoted to other topics, it can be taught at a first year level or it can be taught in higher level courses devoted to differential geometry or to more classical topics. These notes are intended to fill a rather obvious gap in the literature. It treats the classical topics of Euclidean, projective and hyperbolic geometry but uses the material commonly taught to undergraduates: linear algebra, group theory, metric spaces and complex analysis. The notes are based on a course whose aim was two fold, firstly, to introduce the students to some geometry and secondly to deepen their understanding of topics that they have already met. What is required from the earlier material is a familiarity with the main ideas, specific topics that are used are usually redone.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 124 pp. Englisch.

Neuware -Eine Analyse von 300 Fahrzeug-Fu~ganger-Kollisionen mit 150 Obduktionsfallen und 150 klinischen Fallen zeigte, d~ die in der forensischen Pathologie iibliche Rekonstruktion der Ansto~richtung aus Messerer-Briichen am Unterschenkel auch aus klinisch erstellten Ront genbildem moglich ist, wenn Aufnahmen in mindestens zwei Ebenen, moglichst vor und nach der Frakturversorgung, vorliegen. Aus der Richtung der Bruchkeile oder Bruchtra peze konnte die Ansto~richtung bestimmt werden. Der Messerer-Keil zeigt mit der Spitze des Dreiecks die Richtung der Gewalteinwirkung an. Die Ansto~hohe lie~ sich in Verbindung mit den Weichteilbefunden ermitteln, die aber in den klinischen Fallen meist schlecht dokumentiert waren. Die Kollisionsgeschwindigkeit konnte nur aus technischen Parametem errnittelt werden. Die Verletzungen am rechten oder linken Bein ergaben keine Hinweise darauf, von welcher Seite der Ansto~ erfolgte, da immer das Standbein die schwereren Verletzungen aufwies. Bei Kindem lagen infolge der Kbrpergrb~e und des anderen Bruchverhaltens kindlicher Knochen Besonderheiten vor, die aber trotzdem in vie len Fallen eine sichere Rekonstruktion ermbglichten.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 784 pp. Deutsch.

Die von ihr ausgehenden Impulse auf Informations- und Kommunika tionstechnik fUhren zur ErschlieBung neuer Anwendungen und Markte. FUr die elektrotechnische Industrie stellt diese Entwicklung eine Herausforderung in zweifacher Hinsicht dar: FUr die neuen Anwendungsbereiche mUssen produkte und Systemlo sungen geschaffen werden. Mit wachsender Leistungsfahigkeit elektronischer Bausteine muB immer mehr anwendungsspezifisches Wissen in Entwicklung und Fer tigung einbezogen werden. Der letztgenannten Problematik widmet sich diese Fachtagung. Die Erfahrung lehrt, daB groBe Anstrengungen notwendig sind, urn die Methoden, verfahren und Werkzeuge zu erarbeiten, mit denen komplexe elektronische Bauelemente wirtschaftlich entwickelt werden konnen. Auf dem Gebiet der Fertigung derartiger Bauelemente hat die elektro technische Industrie Deutschlands eine gute position im interna tionalen Wettbewerb erreicht. In Entwurf und Entwicklung dagegen droht sich ein schnell wachsender Abstand zu den USA und Japan auf zutun. Dieser Gefahr kann nur mit gemeinsamen, aufeinander abgestimmten Anstrengungen von Wissenschaft und Industr ie begegnet werden. Des halb hat Siemens zu dieser Fachtagung, deren Rahmen das gesamte Gebiet der rechnergestUtzten Entwicklung von hochstintegrierten elektronischen Bausteinen umspannt, die hier tatige deutsche Wis senschaft eingeladen. Die Tagungsthemen reichen vom Design Uber Layout, Architektur, Simulation, Test bis zur Fertigungsvorberei tung. Viele der heute angewandten Methoden und Programme sind - sprUnglich von Hochschulinstituten entwickelt worden, dann von der Industrie Ubernommen, der Praxis angepaBt und in ein umfassendes System integriert worden.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 168 pp. Deutsch.
