An efficient implementation of boundary element methods for computationally expensive Green's functions

An efficient implementation of boundary element methods for computationally expensive Green’s functions

We describe an implementation technique for boundary element methods that greatly reduces the required number of evaluations of the Green’s function. Assuming that evaluating the Green’s function is a costly operation, our approach has a computational cost that is almost independent of the chosen discretization scheme. Nyström methods, collocation methods and Galerkin methods lead to similar co...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

An Efficient Sensitivity Analysis Approach for Computationally Expensive Microscopic Traffic Simulation Models

Microscopic traffic simulators are useful tools for designing, evaluating and optimizing transportation systems. In order for a simulator to accurately describe reality, the corresponding traffic model must be properly calibrated. However, the calibration can be rather difficult when the model is computationally expensive and has many parameters. To overcome these difficulties, Sensitivity Anal...
