finding critical time in a power system

说明：  信号处理,进行信号检测与处理，通过设定threshold来进行信号检测的可信度调整(Credibility adjustment signal processing, signal detection and processing, by setting threshold for signal detection)

预备实验 Matlab软件环境的熟悉，里面一些最简单的只是知识，可以帮助刚入门的学习(Prepared to experiment with Matlab software environment, which is just some of the most simple knowledge that can help just getting started learning)

EEG brain signal anlaysis codes. Extract event-related potential (ERP) compoents from brain signal. Estimate ERP waveforms, and the assoimated single-trial latencies and amplitudes. Estimate spectrum of on-going activities. Two algoithms, dVCA and AESO, are implemeneted. Could be useful for researchers and students in biomeical engineering.

这是对脑电波处理的共空间模式的matlab程序，主要是提取脑电波的空间特征，并进行降维，然后用支持向量机进行分类。(This is the space of brain wave processing of model of the matlab, mainly is the space of the brain wave characteristic extraction, and dimensional reduction, then classified by support vector machines (SVM). )

CDMA信号调制解调，采用直接序列扩频，过加性高斯白噪声下的误码率计算。(the model of CDMA)

matlab 传统板的FEM程序静力分析、模态计算(Analysis, modal calculation program FEM of traditional static matlab plate)

绘制庞加莱截面图 在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(Poincare mapping sections in the phase space properly (should be beneficial to observe the system and changes in movement characteristics, such as the cross-section can not be tangent trajectory, but also can not contain rail line) to select a cross-section, in this section for a total of conjugate variables, such as x1 and X.1 take a fixed value, call this cross-section for the Poincare section, the phase space of the continuous trajectory of the point of intersection with the Poincare cross-section to become cut-off point.)
