这个是用fortran编写的地球物理反演程序，十分经典。一般很难下载到，因为我是学生，所以才有机会跟老师处获得代码，请大家本着学习的目的使用代码，不要用于商业用途和随意转播(This is prepared by fortran geophysical inversion procedure is very classic. Generally very difficult to download because I am a student, so teachers have a chance to obtain the code, please use the spirit of learning of the code, not used for commercial purposes and not to broadcast)

瑞利信道下，psk水声通信系统均衡。此仿真采用lms均衡和DFE均衡器结合，对瑞利信道数据均衡。(The PSK underwater acoustic communication system is balanced under the Rayleigh channel. The simulation uses LMS equalizer and DFE equalizer to balance the Rayleigh channel data.)

GEPHI的一些练习数据，供大家学习交流。gephi有不懂的地方来问我(GEPHI some practice data for all learning exchange. gephi do not know where to ask me)

说明：  Gr data file for lammps including charge

驱动AD5933检测生物阻抗，判断水果的成熟度等级(Detection of bioimpedance by driving AD5933)

热扩散LBM程序,格子玻尔兹曼方法，小红书一维热扩散(program for heat diffusion D1Q3)

此代码用于设计摄像机动态视觉追踪，用户可以圈出目标物体，目标物体移动过程中会一直被跟踪(This code is used to design camera dynamic visual tracking, the user can circle the target object, the target object will be tracked in the process of moving.)

说明：  实现了平方根容积卡尔曼滤波的过程，可以用于非线性滤波(The process of square root cubature Kalman filter is realized.It can be used for nonlinear filtering.)

提出并研制了一种新型电力系统暂态故障模拟再现系统。该系统通过将系统发生故障时故障录波器录下的数据转换为符合IEEE的COMTRADE格式文件，经数据处理软件进行分析后由电脑并口送入多功能继电保护测试仪，最终由测试仪还原成故障时的ＰＴ、ＣＴ二次侧电压、电流信号。该系统对继电保护装置参数整定、事故原因查找及分析等有辅助作用。-proposed and developed a new type of power system transient fault simulation and reconstruction system.IEEECOMTRADE. The system of relay device parameter setting, the cause of the accident investigation and analysis of a supporting role.

The code is aco, ahp, ....
