MuPAD was designed as a parallel system. The design and implemen tation of MuPAD grew out of the desire to efficiently handle large data generated by algorithms used to investigate the group theoretical structure of nonlinear sys tems. Nevertheless, MuPAD outgrew this original goal and was developed as a general purpose system and should be used as such. MuPAD had two major design goals. As already mentioned, firstly we wanted to prm ide a tool for fast and efficient handling of large data. This goal was motivated by the special problems which came up in our research on nonlinear systems, where data of several GB are not unusual. As a consequence of this MuPAD is a parallel computer algebra system working on the basis of a shared memor)' machine. Special interfaces, simulating ~hared memory, will be provided for machines with a different architecture. A sequential version of MuPAD is available which, nevertheless, in its high-end language provides parallel constructs for programming. In this sequential version parallEl blocks are executed at random, thus allowing for logical tests of parallel programs on sequential machines. The sequential MuPAD version is the topic of this refErence manual. The second major design goal was to make sure that future versions of MuPAD could be the basis for a system capable of learning during interactive use. 199 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Discrete-time systems arise as a matter of course in modelling biological or economic processes. For systems and control theory they are of major importance, particularly in connection with digital control applications. If sampling is performed in order to control periodic processes, almost periodic systems are obtained. This is a strong motivation to investigate the discrete-time systems with time-varying coefficients. This research monograph contains a study of discrete-time nodes, the discrete counterpart of the theory elaborated by Bart, Gohberg and Kaashoek for the continuous case, discrete-time Lyapunov and Riccati equations, discrete-time Hamiltonian systems in connection with input-output operators and associated Hankel and Toeplitz operators. All these tools aim to solve the problems of stabilization and attenuation of disturbances in the framework of H2- and H-control theory. The book is the first of its kind to be devoted to these topics and consists mainly of original, recently obtained results. 230 pp. Englisch.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Die hier beschriebenen Versuche wurden im Rahmen der ersten Phase des von mir gelei teten Forschungsprojekts 'Verformungsvermogen von Massivbautragwerken' durchge fiihrt. Die Interpretation der Versuchsergebnisse, ein Vergleich mit Resultaten friiherer Versuche und erganzende theoretische Untersuchungen werden von Herrn Sigrist zur Zeit vorgenommen. Die Ergebnisse dieser Arbeiten sollen in etwa einem Jahr vorliegen und in Form einer Dissertation veroffentlicht werden. Die friiher iibliche separate Numerierung von Versuchsberichten des Instituts fUr Baustatik und Konstruktion der ETH Ziirich wird mit dem vorliegenden Bericht aufge geben; neu werden Versuchsberichte in die fortlaufend numerierte Reihe der iibrigen Berichte unseres Instituts eingegliedert. Neu gestaltet wurde auch der Einband; ein aus einem internen Wettbewerb hervorgegangenes Logo und die Farben Ziirichs -blau und weiss -werden kiinftig unsere Veroffentlichungen zieren.
