Large-scale and high-dimensional data are the main difficulties for Mach number prediction in a wind tunnel system. To solve these issues, based on the multivariate fuzzy Taylor theorem, the Feature Subsets Ensemble (FSE) method has been proposed. However, data sampled from measurements have noise. The FSE uses the entire data set at least once, and for data with noise this property may reduce the...
Based on open-source 3-D graphics engine OSG technique, this paper expounds the framework and function modules of a virtual training scenario editing system of emergency disposal based on VR. Taking a hazmat leakage accident on the road as an example, the prototype system was implemented. Research shows that the scenario editing system can be used to build all kinds of training simulation scenarios...
The cultivation of graduate Students' innovation ability has an extremely important strategic significance. Based on the System Dynamic perspective, analyze various retarding factors of graduate students' innovation ability building, dissect three vicious circle which hinder the improving of graduate students' innovation ability, and conclude that the root causes of graduate Students' innovation ability...
