Improving AOR Method for a Class of Two-by-Two Linear System  [PDF]
Cuixia Li, Shiliang Wu
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.22026
Abstract: In this paper, the preconditioned accelerated overrelaxation (AOR) method for solving a class of two-by-two linear systems is presented. A new preconditioner is proposed according to the idea of [1] by Wu and Huang. The spectral radii of the iteration matrix of the preconditioned and the original methods are compared. The comparison results show that the convergence rate of the preconditioned AOR methods is indeed better than that of the original AOR methods, whenever the original AOR methods are convergent under certain conditions. Finally, a numerical example is presented to confirm our results.

Abstract: A new system of large-diameter waveguide with liquid core for the measurement of liquid density is presented.The main advantage of this system is the relatively high measuring sensitivity. The principle of this system and the effect of construction parameters of the system on the sensitivity are discussed.The results of measurements are nearly in agreement with the theoretical analysis.

International Education Studies , 2011, DOI: 10.5539/ies.v4n3p133
Abstract: In this article, many methods such as the literature study are used to analyze the harmony ideas in the sport, the education, and the development of Taijiquan, and the deep meanings contained in these three aspects are expounded in detail, and the conclusion indicates that Taijiquan is very important both for the public body-building and for the harmonious development of the society.
A Review Research of Errors Caused in Auditing Process
Shiliang Xia
International Journal of Business and Management , 2009, DOI: 10.5539/ijbm.v3n10p154
Abstract: There is a significant growth of behavior economics in the last decade. The goal of the behavior research is aimed at the deviations from rationality in order to improve the predictive power of economic models. In this paper, attached to the specific auditing process, I want to classify the neglecting relevant information due to judgment by representative which causes the bias, or the error of auditing results.
Illustration of Cultural Attributes in China Wushu Routine
Shiliang Yan
Asian Social Science , 2011, DOI: 10.5539/ass.v7n5p166
Abstract: Wushu is the traditional national sports item with the greatest reputation. Its routine pattern is not simple listing and overlying of movements, but crystallization of Chinese people’s artistic creativity and unique thinking mode, which reflects wisdom and ideal pursuit of Chinese people. This article is going to give an illustration to the several cultural attributes implied in Wushu routine and disclose profound connotation of routine culture of Chinese Wushu.
Infinite Mixtures of Multivariate Gaussian Processes
Shiliang Sun
Computer Science , 2013,
Abstract: This paper presents a new model called infinite mixtures of multivariate Gaussian processes, which can be used to learn vector-valued functions and applied to multitask learning. As an extension of the single multivariate Gaussian process, the mixture model has the advantages of modeling multimodal data and alleviating the computationally cubic complexity of the multivariate Gaussian process. A Dirichlet process prior is adopted to allow the (possibly infinite) number of mixture components to be automatically inferred from training data, and Markov chain Monte Carlo sampling techniques are used for parameter and latent variable inference. Preliminary experimental results on multivariate regression show the feasibility of the proposed model.
Multi-view Laplacian Support Vector Machines
Shiliang Sun
Computer Science , 2013,
Abstract: We propose a new approach, multi-view Laplacian support vector machines (SVMs), for semi-supervised learning under the multi-view scenario. It integrates manifold regularization and multi-view regularization into the usual formulation of SVMs and is a natural extension of SVMs from supervised learning to multi-view semi-supervised learning. The function optimization problem in a reproducing kernel Hilbert space is converted to an optimization in a finite-dimensional Euclidean space. After providing a theoretical bound for the generalization performance of the proposed method, we further give a formulation of the empirical Rademacher complexity which affects the bound significantly. From this bound and the empirical Rademacher complexity, we can gain insights into the roles played by different regularization terms to the generalization performance. Experimental results on synthetic and real-world data sets are presented, which validate the effectiveness of the proposed multi-view Laplacian SVMs approach.

Yujun Zheng,Shiliang Ding
Chinese Science Bulletin , 2000, DOI: 10.1007/BF02909763
Abstract: Hamiltonian of an O3 molecule is classicized by using coherent states, and its potential energy surface is obtained. The surface and the contours are plotted. The calculated force constants and dissociation energies are in good agreement with experimental values.
Estimation of genome length
Huidong Mo,Shiliang Gu
Chinese Science Bulletin , 2001, DOI: 10.1007/BF03187005
Abstract: The genome length is a fundamental feature of a species. This note outlined the general concept and estimation method of the physical and genetic length. Some formulae for estimating the genetic length were derived in detail. As examples, the genome genetic length of Pinus pinaster Ait. and the genetic length of chromosome VI ofOryza sativa L. were estimated from partial linkage data.
Preconditioners for Indefinite Linear System from the Helmholtz Equation
Shiliang WU,Cuixia LI
Studies in Mathematical Sciences , 2010,
Abstract: Using the finite difference method to discretize the Helmholtz equation usually leads to a large spare linear system. Since the coefficient matrix of the linear system is frequently indefinite, it is difficult to solve iteratively. The approach taken in this paper is to precondition this linear system with SSOR and ILU preconditioners and then to solve it iteratively by using Krylov subspace method such as LSQR method. Numerical experiments are given in order to demonstrate the efficiency of the presented preconditioners. Key Words: Helmholtz equation; Krylov subspace method; Preconditioner
