This paper studies and compares the domain partitioning algorithms presented by Farhat,1 Al-Nasra and Nguyen,2 Malone,3 and Simon4/Hsieh et al.5,6 for load balancing in parallel finite element analysis. Both the strengths and weaknesses of these algorithms are discussed. Some possible improvements to the partitioning algorithms are also suggested and(More)
In this work, an iterative mesh partitioning approach is proposed to improve the efficiency of parallel substructure finite element computations. This approach employs an iterative strategy with a set of empirical rules that are derived from results of numerical experiments on a number of different finite element meshes. Two test examples are presented to(More)
Background: Nowadays, the use of Closed Circuit Television (CCTV) systems is effective for monitoring traffic, preventing crime, and ensuring safety in many public spaces. However, the effectiveness of CCTV coverage is often achieved through design experience and trial-and-error, instead of being evaluated and visualized using a robust approach. Methods:(More)
ABSTRACT: Since the publication of green building standards from the last decade, the designer of green buildings have often encountered the challenges of limited time but considerable complexity in the process of evaluating their design according to the rules specified in the standards. Also, the design process is usually an iterative one, which includes(More)
In order to evaluate the linkage of schizophrenia to loci at chromosome 15q, we genotyped six microsatellite markers at chromosome 15q11-14 in 52 Taiwanese schizophrenic families. Two phenotype models (narrow: DSM-IV schizophrenia only; and broad: including schizophrenia, schizoaffective, and other nonaffective psychotic disorders) were used to define the(More)
To facilitate information standardization and sharing in Construction Industry, this paper presents a simple but effective approach that maps the UML (Unified Modeling Language) object-oriented information model related to a construction project to an XML schema, then to a Relational DataBase (RDB) schema. First of all, the mapping between UML model and XML(More)
Recently, several domain partitioning algorithms have been proposed to effect load-balancing among processors in parallel finite element analysis. The recursive spectral bisection (RSB) algorithm [l] has been shown to be effective. However, the bisection nature of the RSB results in partitions of an integer power of two, which is too restrictive for(More)
