这个程序再matlab2012b版本上调试成功，以前在毕业设计的时候在网上找到的资料，希望对大家有用，数字水印算法实现（matlab程序包），包含有DCT水印嵌入算法，DWT水印嵌入算法，以及水印攻击和性能测试程序。参考价值极大(This program debug version then matlab2012b success in graduate design information previously found on the Internet when we want to be useful, a digital watermarking algorithm (matlab package), including a watermark embedded DCT algorithm, DWT algorithm embedded watermark, watermark attack and performance testing procedures. Great value)

The plane stress analysis refers to the problems where the thickness of the structure is very small compared to other dimensions of the structure in the XY plane. The plane stress problem is a 2D problem. The stresses in the z direction are considered to be negligible,
 
0, the stress-strain compliance relationship for an isotropic material becomes,

ofdm的通信系统的平台，希望对大家有所帮助(ofdm communication system platform, we want to help)

本文先用灰色GM(1,1)模型对陕西省GDP 做预测, 经过检验, 再用此模型确定另外一些未知指标, 最后通过确定的这些指标用 灰色GM(1,N)模型作预测, 通过比较总结两种模型各自的特点, 从而科学的指导陕西省经济发展,国内生产总值预测模型具有重要的现实意 义。 (This article first gray GM (1,1) models do forecast GDP of Shaanxi province, on examination, then this model to determine other unknown targets, and finally through the identification of these indicators of gray GM (1, N) model for prediction, by Comparison of two models summarize the characteristics of their own, so the guidance of scientific economic development in Shaanxi Province, China' s GDP forecast model has important practical significance.)
