说明：  矩阵，尤其是分块矩阵的分解，删除，调整，可以方便数值计算，减少冗余(Matrix, in particular, block matrix decomposition, delete, adjust, easy numerical calculation, to reduce redundancy)

提出了一种可抗 几何攻击的二值文本图像水印算法. 该算法基于DCT,它将二值图像的DCT、图像的视觉特征向 量和加密技术有机结合起来,在提取水印时不需要原始图像,是一种实用的盲水印算法(We propose a geometric attacks against Binary Text Watermarking Algorithm. The algorithm is based on DCT, it binary image DCT, the image of the visual feature vector and encryption technology combine in the watermark without the original image is a practical blind watermarking algorithm)

MIMO-OFDM的实现，不同点数的OFDM的实现以及SISO 和 MIMO之间的性能对比。(Implementation of MIMO-OFDM, OFDM, and the realization of the performance comparison of different points between SISO and MIMO.)

根据均匀分布陈胜的特点，产生了0-1均匀分布的随机序列(Produced a 0-1 uniformly distributed random sequence)

常规地震假设地下介质是各项同性的，但实际上，是各向异性的。各向异性介质的反射系数随入射角、方位角不同而不同。(Reflection coefficient varies with incident angle and azimuthal angle.)

根据电缆长度计算电缆短路电流。写的不是非常好(Calculation of cable short circuit current according to the length of the cable.)

本文件为基于OMNeT_的Leach协议的仿真改进与研究(This document is based on the improvement and simulation of Leach agreement OMNeT_)

数学模型中Q值法（算法及matlab程序）(Mathematical model in the Q value method matlab program)

PSPICS使用手册,详细介绍了PSPICE的使用方法，是一本很好的入门书籍。(examples for the use of pspice)

运筹学的算法，用matlab实现， matlab for OR one by one (matlab for OR)
