测量6205深沟球轴承的故障振动加速度信号, 对信号进行时频分析, 利用经验模态分解方法将振动信号分解成不同特征时间尺度的固有模态函数,对每个固有模态函数进行Hilbert 变换得到Hilbert 谱,通过谱分析识别轴承的故障部位和类型, 证实Hilbert 谱的有效性(Measuring 6205 deep groove ball bearing fault vibration acceleration signal, the signal frequency analysis, empirical mode decomposition method to decompose the vibration signal into different characteristic time scales of intrinsic mode functions, the Hilbert transform of each intrinsic mode functions Hilbert spectrum, spectral analysis to identify the location and type of bearing failure, confirmed the effectiveness of the Hilbert spectrum)

About Applications of XRD

说明：  4DPSK的matlab仿真例程，能够分块实现，看各位的需要了，仿真没有问题(4DPSK of matlab simulation routines that can block the realization of the need to see you, and simulation is no problem)

一个完整的SVM分类器的程序，matlab编写的。(A complete program SVM classifier.)

We propose a generalized equation to represent a continuum of surface reconstruction solutions of a given non-integrable gradient field. We show that common approaches such as Poisson solver and Frankot-Chellappa algorithm are special cases of this generalized equation.

电流瞬时无功检测 用来检测瞬时无功电流的大小(Current instantaneous reactive detection )

该程序是在LTE场景下实现MIMO无线信道仿真的matlab信道仿真程序，具有好好的实用性。(The program is in LTE scenes MIMO wireless channel simulation matlab channel emulator has good practicality.)
