The increasing demands for quieter machine operation, longer machine life and a greater efficiency of operation have led to the use of sophisticated design aids. Research into rotating machinery is therefore of substantial and increasing importance. Rotordynamics '92 provides a record of some of the most recent research methods and results relating to the design and operation of rotating machinery. The conference is international in character and draws on research from a wide range of respected sources. 448 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is a revised version of a doctoral thesis, submitted in mimeographed fonn to the Faculty of Arts, Uppsala University, 1988. It deals with the notions of struc tural dependence and independence, which are used in many applications of mathe matics to science. For instance, a physical law states that one physical aspect is structurally dependent on one or more other aspects. Structural dependence is closely related to the mathematical idea of functional dependence. However, struc tural dependence is primarily thought of as a relation holding between aspects rather than between their measures. In this book, the traditional way of treating aspects within measurement theory is modified. An aspect is not viewed as a set-theoretical structure but as a function which has sets as arguments and set-theoretical structures as values. This way of regarding aspects is illustrated with an application to social choice and group deci sion theory. Structural dependence is connected with the idea of concomitant variations and the mathematical notion of invariance. This implies that the study of this notion has roots going back to Mill's inductive logic, to Klein's Erlangen Program for geome try and to Padoa's method for proving the independence of symbols in formal logic. 264 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume includes a selection of papers presented at the GAMM/ IFIP-Workshop on IIStochastic Optimization: Numerical Methods and ll Technical Applications , held at the Federal Armed Forces Univer sity Munich, May 29-31, 1990. The objective of this meeting was to bring together scientists from Stochastic Programming and from those Engineering areas, where Mathematical Programming models are common tools, as e.g. Optimal structural Design, Power Dispatch, Acid Rain Abatement etc . Hence, the aim was to discuss the effects of taking into account the in herent randomness of some data of these problems, i.e. considering Stochastic Programming instead of Mathematical Programming models in order to get solutions being more reliable, but not more expen sive. An international programme committe2 was formed which included H.A. Eschenauer (Germany) P. Kall (Switzerland) K. Marti (Germany, Chairman) J. Mayer (Hungary) G.I. Schueller (Austria) Although the number of participants had to be small for technical reasons, the area covered by the lectures during the workshop was rather broad. It contains theoretical insight into stochastic pro gramming problems, new computational approaches, analyses of known solution methods, and applications in such very different technical fields as ecology, energy demands, and optimal reliability of me chanical structures. In particular, the applied presentation also pointed to several open methodological problems. 196 pp. Englisch.

Neuware -Those interested in the relationships between psychological and physiological functions will again and again be impressed by the fact that great individual differences and large situational variability are manifested in psychophysiological data. Psychophysiology from a differential perspective has been an enduring theme throughout the history of personality and temperament research. However, the present book is the first to bear the word differential in its title. Actually, this monography is not only concerned with psychophysiological personality research, but with a much broader program of systematic investigation. Multivariate research methodology permits one to operationalize physiological response profiles, both with regard to lasting differences between persons and the discrimination of situations. In order to determine functional relationships between person characteristics and situational demands, that is, to determine the processes of stimulus-response mediation, one first needs to systemize these various sources of variance in assessment models and subsequently partition the observed covariance. A series of the author's own investigations in the Hamburg and Freiburg laboratories shows just how fruitful this research approach can be.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 416 pp. Englisch.
