多天线的角辐射功率演示,包括2种天线阵,1为线性真,一为任意布置.(A MATLAB GUI platform for displaying the radiation pattern of a narrowband beamformer with user-defined array geometry. User can specify the array geometry, directions of incoming signals, noise level, and the types of beamformer by mouse clicks. Useful for gaining insight about collaborative beamforming in sensor networks and random arrays. )

这是图论里面的一个定理，即Havel定理，它是用来判断一系列的度的序列能否组成一个简单图，在这儿我实现了它。(This is the inside of a theorem of graph theory, that Havel theorem, which is used to determine whether a series of sequences degrees to form a simple graph, here I realized it.)

Encryption algorithms are becoming more necessary to ensure data is securely transmitted over insecure communication channels. FOX is a recently developed algorithm and its structure is based on the already proven IDEA (International Data Encryption Algorithm) cipher. FOX is a symmetric (private key) block cipher. Its top-level structure uses the Lai-Massey scheme and the round functions used in the scheme are substitution permutation networks (SPN). Its flexibility lies in the fact that it can be efficiently implemented in hardware and software. We report some of the first results of implementing the cipher on an FPGA
