Wavelet analysis method for knock detection in injection engine

说明：  写一个程序，用户依照流行歌曲的人气调查表，将相关数据输入到计算机文件中，计算机按照人气指数将排名前十位的歌曲信息显示并存储到文件中。(Write a program, the user in accordance with the popularity of pop music questionnaire, data will be entered into the computer files, the computer will be ranked according to popularity index of the top ten song information display and store the file.)

历史交通流预测，采用matlab编程，预测效果很好(Historical traffic flow forecasting, using matlab programming, forecasting good results)

multi - objective optimisation

用互相关法求相对剩余静校正量；并用时差统计法或相关函数统计法分离，最后可求出记录道的绝对剩余静校正量。(Using cross correlation method the relative residual statics and separated by the difference method or statistical correlation function statistics of the last track can be obtained an absolute residual statics.)

说明：  本文对指纹特征点的提取，特征点的匹配，用matlab进行了实现(In this paper, the fingerprint feature points extraction, feature point matching, was realized with matlab)
