很全的PSO优化SVM，还带例子。希望大家下下去认真研究，支持支持向量机(this is good method of pso optimizing parameters of svm)

In this paper, we analyze the performance of two important mobility management protocols..MIPv6 and HMIPv6. Analytical model is developed for two mobility models- random walk and fluid flow to compute signaling cost, which consists of two components- location update cost and packet delivery cost.

目标跟踪，本文围绕人运动的视觉分析中的重要课题——基于模型的行人跟踪——展开研究,它不仅涉及底层视觉的许多问题,还是高层视觉处理的基础。基于模型的跟踪是解决行人跟踪问题的一般性框架。(A Method of Passing People Tracking and Counting Based on Real- Time Image- Sequence )
