Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The field of nonlinear hyperbolic problems has been expanding very fast over the past few years, and has applications - actual and potential - in aerodynamics, multifluid flows, combustion, detonics amongst other. The difficulties that arise in application are of theoretical as well as numerical nature. In fact, the papers in this volume of proceedings deal to a greater extent with theoretical problems emerging in the resolution of nonlinear hyperbolic systems than with numerical methods. The volume provides an excellent up-to-date review of the current research trends in this area.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 360 pp. Englisch.

Each of these can further be subdivided into game theory and optimal control theory. The central problem of control theory is the so called constrained maximization (which- with slight modifications--is equivalent to minimization). One can then say, heuristically, that the major problem of control theory is to find the maximum of some performance criterion (or criteria), given a set of constraints. The starting point is, of course, a mathematical representation of the performance criterion (or criteria)- sometimes called the objective functional--along with the constraints. When the objective functional is single valued (Le. , when there is only one objective to be maximized), then one is dealing with optimal control theory. When more than one objective is involved, and the objectives are generally incompatible, then one is dealing with game theory. The first paper deals with stochastic optimal control, using the dynamic programming approach. The next two papers deal with deterministic optimal control, and the final two deal with applications of game theory to ecological problems. In his contribution, Dr. Marc Mangel applies the dynamic proQramming approach, as modified by his recent work--with Dr. Colin Clark, from the University of British Columbia (Mangel and Clark 1987}\*--to modelling the 'behavioral decisions' of insects. The objective functional is a measure of fitness. Readers interested in detailed development of the subject matter may consult Mangel (1985). My contributions deal with two applications of optimal control theory.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 116 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The homotopy index theory was developed by Charles Conley for two sided flows on compact spaces. The homotopy or Conley index, which provides an algebraic-topologi cal measure of an isolated invariant set, is defined to be the ho motopy type of the quotient space N /N , where is a certain 1 2 1 2 compact pair, called an index pair. Roughly speaking, N1 isolates the invariant set and N2 is the 'exit ramp' of N . 1 It is shown that the index is independent of the choice of the in dex pair and is invariant under homotopic perturbations of the flow. Moreover, the homotopy index generalizes the Morse index of a nQnde generate critical point p with respect to a gradient flow on a com pact manifold. In fact if the Morse index of p is k, then the homo topy index of the invariant set {p} is Ik - the homotopy type of the pointed k-dimensional unit sphere.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 224 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This book is intended to bring together data and clinical guidelines for those involved in the practice of anaesthesia, whether they be specialists or not. It is designed to be a true handbook that will accompany its owner into the operating theatre, where it will serve as a practical reference guide, not as a textbook. We welcome comment, criticism, and suggestions for improvement of the contents; correspondence may be addressed to the authors at P. O. Box 63, Tygerberg 7505, Republic of South Africa. We wish to acknowledge help received from our colleagues over the years of publication: Dr. T.J.V.Voss, Prof. G.G.Harrison, Dr. C. M. Lewis, Dr. W. B. Murray, Prof. A. R. Coetzee, and Dr. W. L. van der Merwe. Acknowledgement is also made to 'Anaesthesia Guidelines', long since out of print, on which the first edition of this handbook was based in 1978.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Der Band befaßt sich mit der Funktion der Milz und den Folgen ihres Verlustes aus chirurgischer und immunologischer Sicht. Es werden die verschiedenen Möglichkeiten des Immunsystems zur Abwehr bakterieller Infektionen dargestellt und hierauf basierend die relevant erscheinenden Faktoren bei splenektomierten Patienten und im Tierexperiment untersucht. Aufgrund eigener Nachuntersuchungen wird auf die Bedeutung der Postsplenektomiesepsis eingegangen und vor allem die Wertigkeit der autologen Milzreplantation überprüft. Schließlich werden die Prophylaxe und die Therapie der Postsplenektomiesepsis erörtert.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 128 pp. Deutsch.
