SPURIOUS NUMERICAL SOLUTIONS OF DELAY DIFFERENTIAL EQUATIONS

引用

Journal of Computational Mathematics 2006年第2期24卷 181-192页

作者： Hong-jiong Tian Li-qiang Fan yuan-ying zhang Jia-xiang Xiang Department of Mathematics Shanghai Normal University Division of Computational Science E-Institute of Shanghai Universities Shanghai 200234 China Department of Mathematics Shanghai Normal University Shanghai 200234 China

This paper deals with the relationship between asymptotic behavior of the numerical solution and that of the true solution itself for fixed step-sizes. The numerical solution is viewed as a dynamical system in which the step-size acts as a parameter. We present a unified approach to look for bifurcations from the steady solutions into spurious solutions as step-size varies.

Communications in Theoretical Physics 2006年第9期46卷 407-414页

作者： zhang yuan-yuan,~+ ZHENG ying, zhang Hong-Qing Department of Applied Mathematics, Dalian University of Technology, Dalian 116024, China Department of Applied Mathematics Dalian University of Technology Dalian 116024 China

In this paper, we extend the multiple Riccati equations rational expansion method by introducing a new ansatz. Using this method, many complexiton solutions of the (2+1)-dimensional Nizhnik-Novikov-Veselov equations are obtained which include various combination of hyperbolic and trigonometric periodic function solutions, various combination of hyperbolic and rational function solutions, various combination of trigonometric periodic and rational function solutions, etc. The method can be also used to solve other nonlinear partial differential equations.

Dynamic Properties of Two-Dimensional Polydisperse Granular Gases

引用

Communications in Theoretical Physics 2007年第2X期48卷 343-347页

作者： LI Rui zhang Duan-Ming HUANG Ming-Tao SU Xiang-ying CHEN Zhi-yuan ZHU Hong-ying zhang Lin Department of Physics Huazhong University of Science and Technology Wuhan 430074 China

We propose a two-dimensional model of polydisperse granular mixtures with a power-law size distribution in the presence of stochastic driving. A fractal dimension D is introduced as a measurement of the inhomogeneity of the size distribution of particles. We define the global and partial granular temperatures of the multi-component mixture. By direct simulation Monte Carlo, we investigate how the inhomogeneity of the size distribution influences the dynamic properties of the mixture, focusing on the granular temperature, dissipated energy, velocity distribution, spatial clusterization, and collision time. We get the following results： a single granular temperature does not characterize a multi-component mixture and each species attains its own ＂granular temperature＂; The velocity deviation from Gaussian distribution becomes more and more pronounced and the partial density of the assembly is more inhomogeneous with the increasing value of the fractal dimension D; The global granular temperature decreases and average dissipated energy per particle increases as the value olD augments.

Constructions of optimal binary locally repairable codes via intersection subspaces

Science China(Information Sciences) 2024年第6期67卷 418-432页

作者： Wenqin zhang Deng TANG Chenhao ying yuan LUO School of Electronic Information and Electrical Engineering Shanghai Jiao Tong University

Locally repairable codes（LRCs）, which can recover any symbol of a codeword by reading only a small number of other symbols, have been widely used in real-world distributed storage systems, such as Microsoft Azure Storage and Ceph Storage Cluster. Since binary linear LRCs can significantly reduce coding and decoding complexity, constructions of binary LRCs are of particular interest. The aim of this paper is to construct dimensional optimal binary LRCs with disjoint local repair groups. We introduce a method to connect intersection subspaces with binary LRCs and construct dimensional optimal binary linear LRCs with locality 2b（b 3） and minimum distance d 6 by employing intersection subspaces deduced from the direct sum. This method will sufficiently increase the number of possible repair groups of dimensional optimal LRCs, thus efficiently expanding the range of the construction parameters while keeping the largest code rates compared with all known binary linear LRCs with minimum distance d 6 and locality 2b.
