Fast Hybrid Algorithms for High Frequency Scattering
This paper deals with numerical methods for high frequency wave scattering. It introduces a new hybrid technique that couples a directional fast multipole method for a subsection of a scattering surface to an asymptotic formulation over the rest of the scattering domain. The directional fast multipole method is new and highly efficient for the solution of the boundary integral formulation of a ...
متن کاملFast Algorithms for Bayesian Independent Component Analysis
Fast algorithms for linear blind source separation are developed. The fast convergence is rst derived from low-noise approximation of the EM-algorithm given in 2], to which a modiication is made that leads as a special case to the FastICA algorithm 5]. The modii-cation is given a general interpretation and is applied to Bayesian blind source separation of noisy signals.
متن کاملFast Universal Algorithms for Robustness Analysis
In this paper, we develop efficient randomized algorithms for estimating probabilistic robustness margin and constructing robustness degradation curve for uncertain dynamic systems. One remarkable feature of these algorithms is their universal applicability to robustness analysis problems with arbitrary robustness requirements and uncertainty bounding set. In contrast to existing probabilistic ...
متن کاملFrequency Domain Analysis of Adaptive Tracking Algorithms
In this paper, an analysis of the tracking performance of several adaptive algorithms is carried out for the case of model structures with fixed pole positions. Such structures have recently been proposed as an efficient generalisation of the common FIR model structure. The focus of this work is to analyse the tradeoff between noise sensitivity and tracking ability in the frequency domain by il...
