利用有限差分软件Flac3d生成人工地震波，并用于岩土工程动力分析(Using finite difference software Flac3d generate artificial seismic waves, and for dynamic analysis of geotechnical engineering)

自动驾驶车辆轨迹跟踪程序，可以运行，可以出图(Gravitational search algorithm program that can run)

说明：  根据随机给出的二进制信号进行统2ASK调制,画出各个阶段的波形.(According to random binary signals given 2ASK modulation system, draw the various stages of waveform.)

this is the code for DCT color image compression. You can check the compression quality by checking your output image which will be stored in current folder.

determines the intersection points of curves

this coding is related on image processing and this code is very effectively used in detect the faces,iris and finger print for differentiate the fake and real image.the gradient ,mean square algorithm is used.

This calculation shows the evolution of the numerical solution of a simple one-dimensional Laplace s equation in a vacuum. The calculation is repeated 100 times and the values are determined from the previous calculation.

调制识别是非协作通信中的关键技术之一，在电子对抗、软件无线电等领域 应用十分广泛。该过程介于信号检测与解调之间，由于对传输信号没有过多的先 验信息以及在接收端有很多未知的参数，例如：信号功率，载波频率和相位偏移， 时间信息等，导致对调制方式的盲识别是一项很困难的任务。此外，实际中存在 多径衰落、频率选择性和时变信道等问题，使得这项任务变得更具有挑战性。 (The modulation recognition is one of the key technologies of the non-cooperative communication, such as electronic countermeasures and software defination radio, therefore it is such a significant discipline and orientation in the research of communication field. Obviously, without enough knowledge in transmitter and verified parameters about receivers, for example signal power, carrier frequency and phase offsets and so force, it is hard to get the modulation of blind identification. What is more, for the sake of the multipath fading, frequency-selective and time-varying channels in the real scenarios the task is even harder. )
