Based on Stochastic Petri Net (SPN) theory, a formalized model of vehicular 1553B bus system is constructed. The performance indices of the vehicular 1553B bus system are obtained through simulation experiment. Performance indices analysis can provide an important theoretical basis for the design of the vehicular 1553B bus system.
this article gives weight to the study of the environmental pollution degree caused by heavy metal and the finding of the pollution source position. First of all, we rank the pollution degree by the geo-accumulation index, regard it as the assessment set, establish fuzzy relation matrix, and get the comprehensive evaluation results in order to get the pollution degree in different functional areas...
We propose an algorithm for finding out the single or multiple camera calibration planar coded patterns from an image with a complicate background, and provide a kind of patterns design for multi-pattern calibration accordingly. Until recently, the camera calibration planar pattern recognition methods proposed are mainly the recognition of the calibration pattern from images with a single pattern...
The Scanning Electronic Microscopy (SEM) images are usually used to analyze a certain kind of material properties. To get automatic and accurate quantitative research, image processing methods are utilized to analyze surface morphology from the images obtained from SEM. In this paper, we focus on the Activated Carbon Fiber (ACF) SEM material images. K-nearest neighbor smoothing and Lapalacian sharpenning...
