A novel simulation framework based on Service-Oriented Architecture(SOA) is proposed to meet the new requirements for simulation compos ability, this framework is open and is propitious to integration with other systems. A simulation platform is constructed using component-based software engineering to test the feasibility of SOA-based framework, the implementation of simulation service layer and...
In this paper, we propose an efficient algorithm to compute the centroidal Voronoi tessellation in 2D periodic space. We first present a simple algorithm for constructing the periodic Voronoi diagram (PVD) from a Euclidean Voronoi diagram. The presented PVD algorithm considers only a small set of periodic copies of the input sites, which is more efficient than previous approaches requiring full copies...
Text categorization is an important research direction of current information retrieval. The traditional text classification method use the support vector machine (SVM) and the Bayes classification algorithm (etc). On the basis of Rough Set on text categorization, this paper put forward the idea of variable precision rough set model for Chinese text categorization, which use the attribute reduct algorithm...
Characters analysis for space target is the basis of target modeling. Here I analyzed the precession characters of axis-symmetry and non-axis-symmetry targets in midcourse, gave some simple models and computational formulas on precession parameter for targets such as true warhead, bait with same profile, metallic air balloon, space fragment and mother cabin. It has more significance on modeling and...
System-on-Chip is comprehensively applied in the image and signal processing field. With higher demands of customers and increasing complexity of System-on-Chip, System-on-Chip system level design issues become more critical. Hardware/software partitioning is an important step in the system level design. Application feature analysis and early design decision for hardware/software partitioning become...
