Parallel computing in science and engineering : 4th International DFVLR Seminar on Foundations of Engineering Sciences, Bonn, Federal Republic of Germany, June 25/26, 1987 by Rüdiger Dierstein ( Book )
8 editions published in 1988 in English and German and held by 291 WorldCat member libraries worldwide
It was the aim of the conference to present issues in parallel computing to a community of potential engineering/scientific users. An overview of the state-of-the-art in several important research areas is given by leading scientists in their field. The classification question is taken up at various points, ranging from parametric characterizations, communication structure, and memory distribution to control and execution schemes. Central issues in multiprocessing hardware and operation, such as scalability, techniques of overcoming memory latency and synchronization overhead, as well as fault tolerance of communication networks are discussed. The problem of designing and debugging parallel programs in a user-friendly environment is addressed and a number of program transformations for enhancing vectorization and parallelization in a variety of program situations are described. Two different algorithmic techniques for the solution of certain classes of partial differential equations are discussed. The properties of domain-decomposition algorithms and their mapping onto a CRAY-XMP-type architecture are investigated and an overview is given of the merit of various approaches to exploiting the acceleration potential of multigrid methods. Finally, an abstract performance modeling technique for the behavior of applications on parallel and vector architectures is described

Helicopter model rotor-blade vortex interaction impulsive noise scalability and parametric variations ( Book )
1 edition published in 1984 in English and held by 115 WorldCat member libraries worldwide
Acoustic data taken in the anechoic Deutsch-NIederlaendischer Windkanal (DNW) have documented the blade-vortex interaction (BVI) impulsive noise radiated from 1/7-scale model main rotor of the AH-1 series helicopter. Average model-scale data were compared with averaged full-scale, in-flight acoustic data under similar nondimensional test conditions. At low advance ratios (mu = 0.164-0.194), the data scale remarkably well in level and waveform shape, and also duplicate the directivity pattern of BVI impulsive noise. At moderate advance ratios (mu = 0.224-0.270), the scaling deteriorates, suggesting that the model-scale rotor is not adequately simulating the full-scale BVI noise; presently, no proved explanation of this discrepancy exists. Carefully performed parametric variations over a complete matrix of testing conditions have shown that all of the four governing nondimensional parameters -- tip Mach number at hover, advance ratio, local inflow ratio, and thrust coefficient -- are highly sensitive to BVI noise radiation. Keywords: Helicopter noise; Blade vortex interaction; Measured acoustics

Solar thermal energy utilization : German studies on technology and application by M Becker ( Book )
3 editions published in 1987 in English and Undetermined and held by 62 WorldCat member libraries worldwide
The German R+D program "Solares Testzentrum Almeria" (SOTA) provides the scientific basis for the realization of advanced solar technologies including facility modifications, component tests and new lines of development. One of the working packages, WP 300, addresses the "Scientific Support" by the performance of preparatory studies, exploratory laboratory acitivities and qualified expertise. Universities, Research Institutes and Company R + D Entities in Germany are enabled to treat the following aspects: - Meteorological, system and cost investigations, - Development of important components as concentrator, receiver, storage, - Utilization of solar energy for process heat and chemical reactions. In 1988 and 1989 the studies concentrated on the development of components. The reports of the activities were finalized recently and collected in the present volumes. The final reports were printed as received under the responsibility of the autors
