一个50行的Matlab有限元程序（二维非线性问题），执行fem2d_nonlinear.m即可。(A 50-line Matlab finite element program (two-dimensional nonlinear problems), the Executive fem2d_nonlinear.m can.)

无刷双馈电机开环控制系统电机模型电机模型(BDFM MODEL)

该源码是针对一篇避免过度分割提出的一种新的分水岭算法，具体matlab源码，针对各个步骤都给出了具体分析，个人觉得对学习图像分割的有帮助。(The source is to avoid over-segmentation for a proposed a new watershed algorithm matlab source code specific for each step are given a specific analysis, personal feel to learn image segmentation help.)

通过在语音信号中嵌入鲁棒性水印和脆弱性水印，实现对数据的版权保护。(Embedded in the speech signal through robust watermarking and fragile watermarking, copyright protection to achieve the data.)

基于SPWVD变换的跳频信号参数估计和检测机器应用(SPWVD transform-based frequency-hopping signal parameter estimation and testing machines)

说明：  关于电力系统静态稳定的程序，需要的可以下载(the program of powersystem stablity )

This paper presents a method for estimating the spectra of water wave disturbances onfive of the six axes of a stationary, slender body underwater vehicle in an inertia dominated waveforce regime, both in head seas and in beam seas. Inertia dominated wave forces are typical ofthose encountered by a 21 inch diameter, torpedo shaped underwater vehicle operating in coastalwaters and sea state

介绍了坐标变换在异步电机中的应用条件和原则，以便能够快速地在异步电机中选择合适的坐标，提高工作效率．并结合异步电机矢量控制存MT坐标系中变换后，可类似于直流电机的转矩电流分量和磁场电流分量(the vector control of asynchronous motor based on the right coordinate)
