根据对所输入的png格式的真彩图像、小波类型（db9或haar）和相应的阈值进行了三级非标准小波harr或db9的分解和重构，从而达到了对原图像的压缩处理的 (Entered based on the true color of the png format images, wavelet type (db9 or haar) and the corresponding threshold for the three non-standard or harr wavelet decomposition and reconstruction of the db9 to achieve a compression of the original image processing)

计算光子晶体能带结构 使用matlab，程序非常容易理解。还配有说明文档。(Calculation of the photonic crystal band structure using the Matlab program is very easy to understand. Document comes with instructions.)

随机共振模型是检测微弱信号，近期流行的算法，效果不错，从事微弱信号检测和提取的可看下(Stochastic resonance model is to detect weak signals, the recent popular algorithms, good effect, engage in weak signal detection and extraction can look)

請設計一個8位元移位暫存器，規格如下： 當控制線S1，S2輸入為00時，平行載入； 當控制線S1，S2輸入為01時，在一時脈內向右shift 1位元； 當控制線S1，S2輸入為10時，在一時脈內向右shift 2位元； 當控制線S1，S2輸入為11時，在一時脈內向右shift 3位元 (Serial Adder)
