In this paper we introduce a two-sided Arnoldi method for the reduction of high order linear systems and we propose useful extensions, first of all a stopping criterion to find a suitable order for the reduced model and secondly, a selection procedure to significantly improve the performance in the multi-input multi-output (MIMO) case. One application is in micro-electro-mechanical systems (MEMS). We consider a thermo-electric micro thruster model, and a comparison between the commonly used Arnoldi algorithm and the two-sided Arnoldi is performed. 相似文献

After a brief survey of number fluctuations, a topic of current interest in light scattering research, the theory is developed
for a particular case of this type. A laser beam of Gaussian cross section illuminates a volume in which there is a fluctuating
number of identical particles. For incoherent detection the scattered intensities are additive. The interest centers on the
statistics of the total scattered intensity. Starting from the moment generating function, the distribution function of scattered
intensity is computed using two different methods. In an experiment designed to test the computed distributions, agreement
between theory and measurement is found if the mean particle number within the scattering volume exceeds 3. The experimental
procedure is described and some difficulties are explained which so far did not permit application of the theory for particle
numbers much below 3. 相似文献

本文对目前广泛应用于结构非线性分析之中的弧长法进行改进。改进后的弧长法除保持原有优点外，能够在自动跟踪结构非线性平衡路径的同时，进一步求得位于结构平衡睡径任一区段的任意预先指定的荷载水平及相应的变形。本文的方法可以推广应用于求解预先指定的应力或位移。数值算例表明了本文方法的计算精度、效率及可靠性。 相似文献
