Rayleighfadingchannelsimulation

中心逼近时的灰色预测，根据实际情况通过不断调整matlab程序中的m值，达到更高的精度。(Change the grey prediction of background value, through the continuous adjustment of the m value in the matlab program according to the actual situation, to achieve higher accuracy.)

无桥boostPFC的单周控制，参数可调，模型基本正确(No bridge boostPFC single cycle control, adjustable parameters, the model essentially correct)

3机9节点电力系统仿真,发电机数学模型，暂态稳定计算(power system simulation by 3 generators and 9 buses)

Duhem模型辨识程序，给出了迟滞环曲线(identification of Duhem model)

Classic isotropic hardening model

Algorithms for Digital Image Steganography via Statistical Restoration

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.

Fluid Flow in Micron and Submicron Size Channels

The program is for pseudocolor image processing, it can convert a grayscale image to color. The color may not be accurate but quite useful for certain applications.
