电力系统功能强大的资料，介绍了基于PMU的电力系统的状态估计！(It is a good paper！)

使用CW方程，使用最小能量，采用脉冲推力，实现在一天内两航天器的交会对接。本质上就是一个交会轨道优化问题，由给定的条件优化选取设计变量，使目标函数得到最优值。(Using the CW equation, use the minimum energy, the use of pulse thrust, to achieve in a day two spacecraft rendezvous and docking. Is essentially an intersection orbit optimization problem, by the given conditions to optimize the selection of design variables, so that the objective function to get the optimal value.)

ABAQUS中硅材料参数定义方法，采用python参数化建模(How to define the anisotropic parameters of silicon in ABAQUS through python.)

数据汇总 ，对数据量比较大的数据进行汇总，分析 ，比对(Data collection, data larger than the data aggregation, analysis, comparison)

说明：  用于面板数据平稳性问题（单位根）的MW检验(MW test for panel data stationarity (unit root))

现在很好用的一个BBS哦 是ACCESS的()

道格拉斯-普克算法 (Douglas– Peucker algorithm，亦称为拉默-道格拉斯-普克算法、迭代适应点算法、分裂与合并算法)是将曲线近似表示为一系列点，并减少点的数量的一种算法。它的优点是具有平移和旋转不变性，给定曲线与阈值后，抽样结果一定。(The Douglas - puke algorithm (Douglas - Peucker algorithm, also called the lamer - Douglas - puke algorithm, iterative adaptive point algorithm, split and merge algorithm) is an algorithm that approximatively represents a curve as a series of points and reduces the number of points. It has the advantages of translation and rotation invariance. After a given curve and threshold, the sampling result is certain.)

this is a basic face detection system.
