For that purpose, we computed the 3D temperature distribution in a dry type transformer by solving the Poisson equation with source terms specific to the topology under scope, that is, heat generation by Joule losses and eddy currents, as well as natural cooling on the outside of the metal casing. Our approach is based on the assumption that heat transfer in the electrical device is predominantly diffusion. The solver used for this problem is the well-know BICCG (block incomplete Choleski conjugate gradient).","PeriodicalId":444003,"journal":{"name":"Proceedings.

{"title":"Parallel Lanczos bidiagonalization for total least squares filter in robot navigation","authors":"L. Yang","doi":"10.1109/PCEE.2002.1115314","DOIUrl":"https://doi.org/10.1109/PCEE.2002.1115314","url":null,"abstract":"In the robot navigation problem, noisy sensor data must be filtered to obtain the best estimate of the robot position. The discrete Kalman filter, which usually is used for prediction and detection of signals in communication and control problems has become a commonly used method to reduce the effect of uncertainty from the sensor data. However, due to the special domain of robot navigation, the Kalman approach is very limited. The use of total least squares filter has been proposed (Boley and Sutherland, 1993) which is capable of converging with many fewer readings and achieving greater accuracy than the classical Kalman filter. The main disadvantage of those approaches is that they can not deal with the case where the noise subspace is of dimension higher than one. Here a parallel Krylov subspace method on parallel distributed memory computers which uses the Lanczos bidiagonalization process with updating techniques is proposed which is more computationally attractive to solve the total least squares problems. The parallel algorithm is derived such that all inner products of a single iteration step are independent. Therefore, the cost of global communication which represents the bottleneck of the parallel performance on parallel distributed memory computers can be significantly reduced. This filter is very promising for very large data information and from our very preliminary experiments we can obtain more precise accuracy and better speedup.","PeriodicalId":444003,"journal":{"name":"Proceedings.

It is based on agent technology, and on the idea of separating description and composition language from biding, i.e., from specification of data format (exchanged by applications) and transport protocol. Usually, the biding is an integral part of description language, e.g., WSDL, and DAML-S. Starting with this idea, a simple service description language is constructed as well as a composition protocol is specified. Agents play crucial role in our approach; they are responsible for service composition.","PeriodicalId":444003,"journal":{"name":"Proceedings.
