元胞自动机:森林火灾模型
规则:
(1)正在燃烧的树变成空格位;
(2)如果绿树格位的最近邻居中有一个树在燃烧,则它变成正在燃烧的树;
(3)在空格位,数以概率p生长;
(4)在最近的邻居中没有正在燃烧的树的情况下树在每一时步以概率f(闪
电)变为正在燃烧的树。( Cellular Automata: Forest Fire model Rule: (1) burning of trees into a space bit (2) If the tree can notably nearest neighbor has a tree in the burning, then it turned into being burning tree (3) in the space bit, a few with probability p growth (4) In the nearest neighbor is not burning under the tree the tree in each time step with probability f (flash electricity) Variable for the burning trees.)

dct
在一个图像块中调整两个(或多个) DCT系数的相对大小。将描述一个使用数字图像作为载体的系统。在编码处理中,发送者将载体图像分成8×8的像素块,每一块只精确地编码一个秘密信息位。嵌入过程开始时,首先伪随机地选择一个图像块bi,用它对第i个消息比特进行编码。令Bi=D{bi}为DCT变换后的图像块。
在通信开始前,发送者和接收者必须对嵌入过程中使用的两个DCT系数的位置达成一致,让我们用(u1,v1)和(u2,v2)来表示这两个索引。这两个系数应该相应于余弦变换的中频,确保信息保存在信号的重要部位(从而使嵌入信息不容易因JPEG压缩而完全丢失

cthd39-40
MATLAB实现对该系统的潮流计算。需要MATLAB语言编制程序形成节点导纳矩阵、形成雅克比矩阵、用高斯消去法解修正方程式,并编写输出程序用以输出节点导纳矩阵、节点电压(包括电压的相角和幅值)、以及各支路的首端功率、末端功率和功率损耗(MATLAB implementation of the system flow calculation. MATLAB programming language requires the formation of the node admittance matrix, Jacobian matrix formed by modified Gaussian elimination method for solving equations, and write out procedures for the admittance matrix of the output node, the node voltage (including the voltage phase angle and amplitude), and the first end of each branch of power, end power and power loss)
