提出了一种求解电磁场有限元 边界元混合法所生成的线性方程组的有效方法 ———内观 法结合多波前法.由于该线性方程组的系数是一个部分稀疏部分满填充的矩阵,为了加速求解,应用内观法将系数矩阵分为 2块,一块是有限元法形成的稀疏矩阵,另一块是边界元法生成的满阵,然后用多波前法求解稀疏矩阵方程,用高斯 约当消去法解满阵方程. 采用该方法,计算了二维多层介质柱体的雷达散射截面.计算结果表明,该方法的计算效率远远高于传统的高斯法.(Proposed for solving mixed finite element boundary element linear equations generated by an effective method of Vipassana--- a combination of multi wave front method. Since the coefficients of linear equations is a part of the sparsely populated part of the full matrix, in order to speed up the solution, application of Vipassana coefficient matrix is ​ ​ divided into two, one is the finite element method for the formation of the sparse matrix, the other is the boundary element method generates the full array, and then use the multifrontal method for solving sparse matrix equation Gauss Jordan elimination method with full matrix equation solution. use this method to calculate the two-dimensional multi-layer dielectric cylinder of the radar cross section. The results show the computational efficiency of this method is much higher than the traditional Gaussian law.)

这是我本科毕业设计论文《基于混沌序列的加密图像隐藏技术的设计与实现》，就是把一张图片加密后隐藏在载体图像中，可以抵御各种攻击，用到了Matlab，里面包括开题报告，论文，可执行程序。本文系统介绍了混沌加密、信息隐藏技术。归纳了混沌加密、信息隐藏的分类、特性与应用，给出了混沌加密、信息隐藏的原理和基本框架以及其性能的评价方法，介绍了几种图像的攻击方法。实现了一种混沌加密和图像隐藏的方法。使用混沌加密对待隐藏图像进行加密后嵌入载体图像中，并对嵌入待隐藏图像的载体图像进行了几种攻击以验证其鲁棒性。本系统运用MATLAB编程实现对图像的混沌加密，运用LSB算法将加密后图像嵌入载体图像中，并能承受图像剪切，图像增亮，图像变暗，增加对比度，减低对比度，添加积性噪声，添加高斯噪声，旋转45度，直方图均衡化等一定程度的毁损和各种攻击检测，仍然能解密得到原图像，原图像清晰可辨，鲁棒性非常好。总之本文较好的实现了基于混沌序列的加密图像隐藏技术。(This is my graduation design thesis Design and implementation of chaotic sequence image hiding technique based encryption is encrypted to hide the picture in the carrier image, can withstand a variety of attacks, uses Matlab, which includes opening report, thesis, an executable program. This article describes the chaos encryption system, information hiding technology. Summed up the chaos encryption, information hiding classification, characteristics and application, given the chaotic encryption, information hiding principle and basic framework and its performance uation methods, and introduces the method of attack several images. It implements a chaotic encryption and hidden image method. After using Chaotic Encryption treat hidden image encryption embedded vector images, vector images and embedded image to be concealed several attacks carried out in order to verify its robustness. This system using MATLAB programming chaotic image encryption, use LSB algorithm encrypted image is em)
