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)
SUMMARY This paper studies and compares the domain partitioning algorithms presented by Farhat, Al-Nasra and Nguyen, Malone, and Simon/Hsieh et al. 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)
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)
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 t o(More)
This paper presents the experiences of improving an existing surveyor-training tool, called SimuSurvey, using a user-centered approach. As few users were involved during the initial development of SimuSur-vey, many instructors and students were skeptical about the innovative application of SimuSurvey in actual surveying classes. To address this problem, we(More)
