Degenerate scale problem arising from curved rigid line inclusion
Authors: Chen Y. Z. , Lin X. Y. , Wang Z. X. 
Published: September 2008

AbstractThis paper investigates the degenerate scale problem arising from the curved rigid line inclusion. The problem is modeled by a continuous distribution of the body force along the prospective site of the curve. In the first step, the problem is formulated on the configuration of the degenerate scale, and an integral equation is suggested. Later, after using a modification for the coordinates, the problem is solved in a modified scale or in the normal scale. From the solution of the integral equation in the normal scale, the degenerate scale will be obtained immediately. Finally, several numerical examples are given. From computed results it is proved that the degenerate scale depends only on the configuration of the curve and does not depend on the initial normal scale used.

Finite volume method for convection–diffusion–reaction equation on triangular meshes
Authors: Phongthanapanich S. , Dechaumphai P. 
Published: September 2008

AbstractAn explicit high‐resolution finite volume method is proposed for solving a two‐dimensional convection–diffusion–reaction equation on triangular meshes. Taylor's series expansion is used to formulate the higher‐order reconstruction of unknown quantities at the cell faces. The concept of the finite element technique is applied to estimate the gradient quantities at the cell faces. Numerical test cases have shown that the method does not require any artificial diffusion to improve the solution stability. The robustness and the accuracy of the method have been evaluated by using the available analytical and numerical solutions of the two‐dimensional pure‐convection, convection–diffusion, and convection–diffusion–reaction problems.

A parallel, adaptive finite element scheme for modeling chemotactic biological systems
Authors: Kirk Benjamin S. , Carey Graham F. 
Published: September 2008

AbstractThis paper considers the numerical approximation of complex spatial patterns and rapidly evolving transients in chemotactic biological systems using parallel adaptive multiscale schemes and algorithms. Transport processes in such biological systems are typically modeled by coupled systems of nonlinear reaction–diffusion equations. For example, a model of this form has been proposed for studying chemotaxis in bacteria colonies. In the present study, we develop a variational formulation for this model leading to an approximate finite element scheme with adaptive time stepping and local adaptive mesh refinement/coarsening algorithms. The parallel adaptive solution algorithm is presented in detail and applied to investigate the effect of chemotaxis in spot formation behind concentric advancing concentrations fronts. Numerical results concerning the accuracy, efficiency, and performance of the algorithm are also presented. Copyright © 2008 John Wiley & Sons, Ltd.
Assembling sparse matrices in MATLAB
Authors: Zlotnik Sergio , Díez Pedro 
Published: September 2008

AbstractThe assembly of sparse matrices is a key operation in finite element methods. In this study we analyze several factors that may have an influence on the efficiency of the assembly procedure.Different insertion strategies are compared using two metrics: a Cost function (the number of memory movements) and actual computing time. An improved algorithm implemented in MATLAB is proposed. It reduces both memory operations and computing time for all tested cases.The efficiency of the assembly process is found to be highly dependent on node and element numbering. The effect of the classic reverse Cuthill–McKee algorithm is, in most cases, positive and reduces computation costs.Finally, the case where a sparse matrix has to be re‐assembled at each time step is studied. The efficiency of the assembly is improved if the matrix pattern is entirely or partially inherited from previous steps. Copyright © 2008 John Wiley & Sons, Ltd.
Numerical simulation of canine bodily movement
Authors: Qian Yingli , Liu Zhan , Fan Yubo 
Published: September 2008

AbstractThe aim of this study was to develop finite element (FE) models to simulate bodily movement of an orthodontic treatment of mandibular canine with decayed loads during a therapy period (4 weeks). The normal strain of periodontal ligament was assumed as the key mechanical stimulus for the surface bone remodeling. During the simulation processes, changes in tooth position and in the geometry of the tooth supporting structures and the decayed loads were taken into account. In this numerical simulation, the tooth movement displacements were 1.00 mm in the end of the therapy. The results of the simulation were similar to the observed in clinical studies. It was acceptable to simulate clinical tooth movements by FE method based on these mechanical assumptions. Such a numerical simulation would allow the understanding of tooth movements and help in better planning of individual strategies. Copyright © 2008 John Wiley & Sons, Ltd.
Resource selection in grid: a taxonomy and a new system based on decision theory, case‐based reasoning, and fine‐grain policies
Authors: Nassif Lilian Noronha , Nogueira José Marcos , de Andrade Flá vio Vinícius 
Published: September 2008

AbstractResource selection on current brokers still presents challenges for achieving the best solution in the decision‐making process, especially when considering many factors. We approach this problem considering user preference for specific resource selection objectives such as expected performance for an application execution, resource access restriction, execution application cost, and resource reliability. For each objective, we employ different techniques and combine them in a decision theory model. By considering performance in the selection process, we use the case‐based reasoning technique based on similar past job executions to predict a new job time execution. With the resource access restriction as a selection factor, we develop a fine‐grain policy‐based model for distributed resource access verification. Unlike a global access policy, which applies to all resources in a virtual organization, a fine‐grain policy establishes rules for specific resources and users. In this case, a previous access restriction verification prevents a resource selection, which may deny access to a requisition, resulting in an unsuccessful submission. The decision model uses the multi‐attribute utility theory, which relates the important objectives above and allows different proportions of user preferences for each objective. The complete solution is distributed and implemented using a multi‐agent system, acting as a resource broker. All models of this paper are analyzed in a real environment, presenting appropriate functional behaviors. Results show that our prediction model is accurate and efficient in the prediction process and our distributed model runs faster than centralized approaches and considers access restriction heterogeneities.

Malleable iterative MPI applications
Authors: El Maghraoui K. , Desell Travis J. , Szymanski Boleslaw K. , Varela Carlos A. 
Published: September 2008

AbstractMalleability enables a parallel application's execution system to split or merge processes modifying granularity. While process migration is widely used to adapt applications to dynamic execution environments, it is limited by the granularity of the application's processes. Malleability empowers process migration by allowing the application's processes to expand or shrink following the availability of resources. We have implemented malleability as an extension to the process checkpointing and migration (PCM) library, a user‐level library for iterative message passing interface (MPI) applications. PCM is integrated with the Internet Operating System, a framework for middleware‐driven dynamic application reconfiguration. Our approach requires minimal code modifications and enables transparent middleware‐triggered reconfiguration. Experimental results using a two‐dimensional data parallel program that has a regular communication structure demonstrate the usefulness of malleability. Copyright © 2008 John Wiley & Sons, Ltd.
An abstract layered model for Web‐inclusive distributed computing leading to enhancing GRIDSpace with Web 2.0
Authors: Dillon Tharam S. , Wu Chen , Chang Elizabeth 
Published: September 2008

AbstractService‐oriented computing (SOC), Grid computing, and Web2.0 computing have increasingly received momentum in both research and industry. In this paper, we propose an abstract Web‐inclusive distributed computing model (WIDCOM) in order to analyse these three important distributed computing paradigms. We then advance the notion of software in existing Grid services as discussed in open Grid services architecture, which provides software middleware or wrappers for accessing hardware resources towards the notion that the resources provided can be hardware, software, or hybrid hardware/software. It also proposes an approach using the integration of Grid service, semantic Grid, and Web2.0 to overcome some of the limitations of the existing Web services architecture, which relies on having the Web version of the RPC mechanism and thus has difficulty in dealing with massive scale of user participation and communication across the Internet. The new approach produces a novel Grid architecture—GRIDSpace. Copyright © 2008 John Wiley & Sons, Ltd.
Adaptation rule learning for case‐based reasoning
Authors: Li Huan , Li Xin , Hu Dawei , Hao Tianyong , Wenyin Liu , Chen Xiaoping 
Published: September 2008

AbstractA method of learning adaptation rules for case‐based reasoning (CBR) is proposed in this paper. The resource space model and the semantic link network are applied in case‐base construction for efficient resource management and reuse. Adaptation rules are generated from the case‐base with the guidance of domain knowledge, which is also extracted from the case‐base. The adaptation rules are refined before they are applied in the revision process. General domain knowledge is brought in to help accurate similarity computing. After solving each new problem, the adaptation rule set is updated by an evolution module in the retention process. The results of our experiment show that the obtained adaptation rules can improve the performance of the CBR system compared with a retrieval‐only CBR system. The average solution difference error is decreased by 46.56%. Copyright © 2008 John Wiley & Sons, Ltd.
Formation of virtual organizations in grids: a game‐theoretic approach
Authors: Carroll Thomas E. , Grosu Daniel 
Published: September 2008

AbstractApplications require the composition of resources to execute in a grid computing environment. The grid service providers (GSPs), the owners of the computational resources, must form virtual organizations (VOs) to be able to provide the composite resource. We consider grids as self‐organizing systems composed of autonomous, self‐interested GSPs that will organize themselves into VOs with every GSP having the objective of maximizing its profit. Using game theory, we formulate the resource composition among GSPs as a coalition formation problem and propose a framework to model and solve it. Using this framework, we propose a resource management system that supports the VO formation among GSPs in a grid computing system. Copyright © 2008 John Wiley & Sons, Ltd.
