A general deflation technique for solving arbitrary systems of linear equations was described in Burrage et al. (1994a). This technique can be used with any iterative scheme. As the iterations proceed information is obtained about the eigenvalues of the iteration matrix which either cause slow convergence or divergence. These eigenvalues (and associated eigenvectors) are then deflated into a stiff subspace. This then leads to a coupled ...

Die Anordnung von ausgeweiteten Radstreifen in Knotenzufahrten zur Verbesserung der Sicherheit und des Komfortes der Zweiradfahrer erscheint aufgrund der vorliegenden Untersuchung in Ausnahmefällen sinnvoll.

Environmental models, such as the Pasture Model, require large computing resources to give results within reasonable time frames. This report focuses on the design and implementation of a parallel version of an ADVISE server running the Pasture Model on the Intel Paragon. In order to make the most efficient use of this computing resource, it is first necessary to perform a thorough analysis of the message passing, file I/O and computation ...
