基于遗传算法，进而优化惩罚因子，核函数参数的的支持向量机进行分类(GA SVM classification)

采用simulink对duffing和lorenz混沌系统进行仿真,然后又对lorenz混沌系统的进行延时反馈控制和同步控制,另外还有一个基于simulink的滑模控制,实现方便,效果不错!(Duffing using simulink for lorenz chaotic systems and simulation, and then lorenz chaotic systems on the conduct of delayed feedback control and synchronization control, there is another of the sliding mode control based on simulink to realize the convenience, good results!)

阵列天线方向图随天线数目变化而变化的图像。(Array antenna pattern varies with changes in the number of antennas images.)

设计一个简单的GUI界面，对导入的音频文件进行时域特性分析。计算其时域波形、平均幅度、短时能量、短时过零率。对该音频文件进行加噪处理，分析其时域波形变化。设定一个固定时长，对该音频添加回声并保存为“*.wav”格式文件。 对音频文件的时域分析是对音频文件进行传输、降噪及其他再编辑的基础。其中短时能量可用作清浊音区分的标准和语音起始点的判断。短时过零率可用作判断有声段与无声段和从背景噪声中提取语音信号。 (Design a simple GUI interface that time domain characteristics analysis on import audio files.Calculate the average time domain waveform, amplitude, short-time energy and short-time zero crossing ratio.Add to deal with the noise of the audio files, analyze the changes in the time domain waveform.To set a fixed time, to add the audio echo and saved as a *. Wav format file. The time domain analysis of the audio file was transmitted to audio files, noise reduction and other editor again.The short-time energy voiced distinguish between standard and can be used as a clear voice starting point judgement.Short-time zero crossing ratio can be used as a judgment audio segment and silent segment and extract speech signal background noise.)
