压缩感知重构算法之稀疏度自适应匹配追踪(SAMP)(Sparse degree adaptive matching tracking (SAMP) of compressed sensing reconstruction algorithm)

此zip文件包含lambda算法（Matlab实现），还有基于此算法的demo程序，程序的说明文档也包含在zip文件中(This zip file contains the algorithm which designed with matlab, a demo program and the algorithm documation also contained in this zip file. )

Delphi 卡片填涂助手源码，没搞明白这个小程序的用途，反正在Delphi7环境下可以顺利编译，运行界面如图所示，信息卡填涂助手，不知道基于什么数据库，送给喜欢Delphi的朋友研究吧。

说明：  An Android File Manager source code that supports decompression can also be used for routine operations such as copying, moving, deleting and renaming. When compressing files, they can only be compressed into ZIP format, not rar format. Decompression also supports ZIP format tightly. Source code has more detailed annotations.

用matlab产生一个频率为1Hz的余弦信源 ，设载波频率20Hz， ,试画出： ? AM及DSB调制信号的时域波形； ? 采用相干解调后的AM及DSB信号波形； ? AM及DSB已调信号的功率谱； ? 调整载波频率及m0，观察分的AM的过调与DSB反相点现象。(A cosine source with a frequency of 1Hz is generated by MATLAB, and the carrier frequency 20Hz is set. The time domain waveform of AM and DSB modulation signals; Adopt coherent demodulation of AM and DSB signal waveforms, The power spectrum of AM and DSB modulated signals, Adjust the carrier frequency and M0, observe the AM overshoot and DSB inverting point phenomenon.)

利用emd分解轴承振动信号，并通过改进阈值函数来筛选IMF分量，最后对分量做包络分析，诊断出故障类型。(Using emd to decompose the bearing vibration signal, the IMF component was selected by improving the threshold function, and finally the component was enveloped and analyzed to diagnose the fault type.)

说明：  MCMC方法是一种重要的模拟计算方法，马尔可夫链蒙特卡尔理论(Markov chain Monte Carlo：MCMC)的研究对建立可实际应用的统计模型开辟了广阔的前景。90年代以来，很多应用问题都存在着分析对象比较复杂与正确识别模型结构的困难。现在根据MCMC理论，通过使用专用统计软件进行MCMC模拟，可解决许多复杂性问题。此外，得益于MCMC理论的运用，使得贝叶斯(Bayes)统计得到了再度复兴，以往被认为不可能实施计算的统计方法变得是很轻而易举了。(The MCMC method is an important simulation method. The research of Markov chain Monte Carlo:MCMC (Markov) has opened up a broad prospect for the establishment of a practically applicable statistical model. Since 90s, many application problems have been difficult to analyze the complexity of the analysis objects and to identify the structure of the model correctly. Now, according to the MCMC theory, MCMC simulation can be done by using special statistical software to solve many complex problems. In addition, thanks to the application of MCMC theory, Bias's (Bayes) statistics has been revived again, and the statistical method which was previously considered impossible to carry out the calculation became very easy.)

vb写的扫雷外挂源码,学习内存操作的朋友不妨可以看看呵呵(vb wrote mine external source, a friend may wish to study memory operations can see Oh)

说明：  利用元胞自动机，加入社会力等因素，正式模拟了灾害发生时人员疏散应急情况，可获得人员疏散时间。(By using cellular automata and adding social forces, the emergency situation of evacuation is simulated and the evacuation time is obtained.)
