Computational power and memory requirements for this approach are identified and compared to the performance of current computer architectures by benchmarking different processors. It is shown, that the performance of special purpose hardware, like neurocomputers, is between one and two orders of magnitude higher than the performance of mainstream hardware. On the other hand, the calculation of small neural networks is performed more efficiently on mainstream processors. Based on these results a novel concept is developed, which is tailored for the efficient calculation of bidirectional associative memories. The computational efficiency is further enhanced by the application of algorithms and storage techniques which are matched to characteristics of the application at hand.}, language = {en} } @incollection{GrossMuellerHertingetal.1997, author = {Groß, Rolf Fritz and M{\"u}ller, D. and Herting, D. and Schneemann, A. and Renz, Ulrich}, title = {Modulare Messdatenerfassung in Forschung und Lehre}, series = {Virtuelle Instrumente in der Praxis : Begleitband zum Kongress VIP '97}, booktitle = {Virtuelle Instrumente in der Praxis : Begleitband zum Kongress VIP '97}, editor = {Rahman, Jamal and Jaschinski, Hans}, publisher = {H{\"u}thig}, address = {Heidelberg}, isbn = {978-3-7785-2667-5 Pp.}, pages = {282 -- 288}, year = {1997}, abstract = {The Lehrstuhl f{\"u}r W{\"a}rme{\"u}bertragung und Klimatechnik at the Aachen University of Technology operates several test facilities to investigate fundamentals of heat and mass transfer supported by the Deutsche Forschungsgemeinschaft, the Minister f{\"u}r Forschung und Technologie and the industry. In order to get high-resolution and reproselection of hardware components is as critical as the design of software routines to perform successful and accurate measurements. In the following the development of the measurement and control system for three different test facilities is presented and discussed.
