Hybrid SVM／HMM Method for Face Recognition

A face recognition system based on Support Vector Machine(SVM) and Hidden Markov Model (HMM) has been proposed. The powerful discriminative ability of SVM is combined with the temporal modeling ability of HMM. The output of SVM is moderated to be probability output, which replaces the Mixture of Gauss (MOG) in HMM. Wavelet transformation is used to extract observation vector, which reduces the data dimension and improves the robustness.The hybrid system is compared with pure HMM face recognition method based on ORL face database and Yale face database. Experiments results show that the hybrid method has better performance.     

考虑产品结构的供应链设计决策模型及其博弈分析

结合供应链运作的特点,从MRP 中的物料单(BOM)入手考虑产品结构建立了以供应链收益最大化为目标的多层供应链整体设计决策经济模型.通过该模型可将企业运作层的参数与供应链战略层的决策变量结合在一起,使供应链核心企业能够更加灵活的对原料与配件进行整体生产指派.最后文章证明了决策模型的解是符合联盟博弈核心概念的,这样根据决策模型得到的生产指派关系方案保证了供应链整体结构的稳定性.

Earthquake Resistant Engineering and Application of Seismic Zonation Map of China

China is a country with high seismieity. It is very important for industry and structure to fortify against earthquakes. In this paper the outline of seismicity in China, the criteria for fortification against earthquakes and the contents of seismic zonation map of China are described. The contents of seismic safety evaluation for major construction projects, such as large dams, large bridges, long distance pipe lines for transporting oil and natural gas, nuclear plants, petrochemical enterprises and so on, are presented. Some geological disasters caused by destructive earthquake, such as earthquake-caused collapse and landslide, liquefaction of saturated soll and earthquake fault and so on, are also presented. Preventive countermeasures for these disasters are discussed.
