Dynamic Simulation of Distribution Networks Using Multi-stage Discontinuous Galerkin Method
《CSEE Journal of Power and Energy Systems》2024年第1期185-196,共12页Ruizhi Yu Wei Gu Weiqi Liu Peixin Li Wei Liu 
Dynamic simulation plays a fundamental role in security evaluation of distribution networks(DNs).However,the strong stiffness and non-linearity of distributed generation(DG)models in DNs bring about burdensome computa...

An Approximate Linear Solver in Least Square Support Vector Machine Using Randomized Singular Value Decomposition
《Wuhan University Journal of Natural Sciences》2015年第4期283-290,共8页LIU Bing XIANG Hua 
Supported by the National Natural Science Foundation of China(10901125,11471253)
In this paper, we investigate the linear solver in least square support vector machine(LSSVM) for large-scale data regression. The traditional methods using the direct solvers are costly. We know that the linear equ...

Asymptotically Optimal Detection of DCT-Domain Watermarks Using an Approximate Alpha-Stable Prior
《Chinese Journal of Electronics》2009年第2期335-337,共3页SUN Zhongwei WU Juying GUO Qingrui 
This paper proposes an asymptotically optimal watermark detector in Discrete cosine transform (DCT) domain images. The Gaussian mixture model as an analytical approximation of alpha-stable distribution is chosen to ...

NUMERICAL SOLUTION OF THE UNSTEADY EULER EQUATIONS FOR AIRFOILS USING APPROXIMATE BOUNDARY CONDITIONS被引量:4
《Acta Mechanica Sinica》2003年第5期427-436,共10页高超 罗时钧 刘锋 
This paper presents an efficient numerical method for solving the unsteady Euler equations on stationary rectilinear grids. Boundary conditions on the surface of an airfoil are implemented by using their first-order e...
