好例子网_pareto前沿面
说明: 其中x是任何一个大于xmin的数,xmin是X最小的可能值(正数),k是为正的参数。帕累托分布曲线族是由两个数量参数化的:xmin和k。(Where x is any number greater than xmin,xmin is the smallest possible value of x (positive), and k is a positive parameter the Pareto family of distribution curves is parameterized by two quantities :xmin and K)

图片隐写术
载体文件(cover file)相对隐秘文件的大小(指数据含量,以比特计)越大,隐藏后者就越加容易。
因为这个原因,数字图像(包含有大量的数据)在因特网和其他传媒上被广泛用于隐藏消息。这种方法使用的广泛程度无从查考。例如:一个24位的位图中的每个像素的三个颜色分量(红,绿和蓝)各使用8个比特来表示。如果我们只考虑蓝色的话,就是说有2^8种不同的数值来表示深浅不同的蓝色。而像11111111和11111110这两个值所表示的蓝色,人眼几乎无法区分。因此,这个最低有效位就可以用来存储颜色之外的信息,而且在某种程度上几乎是检测不到的。如果对红色和绿色进行同样的操作,就可以在差不多三个像素中存储一个字节的信息。
更正式一点地说,使隐写的信息难以探测的,也就是保证“有效载荷”(需要被隐蔽的信号)对“载体”(即原

rtmplite-master
说明: The siprtmp module implements a SIP-RTMP gateway. Please see the google code project for details on demo instructions and support information. The project description is contained in siprtmp.py file itself. The command line of siprtmp is same as rtmp, hence just replce rtmp by siprtmp in the following example to start the gateway.

基于神经网络的滑坡预测及其控制研究
说明: 本文针对滑坡预测预报这一复杂性问题提出一种基于前向反馈传播(BP)神经网络的预测模型,描述了滑坡系统输入输出之间的非线性关系。为克服 BP 网络后期收敛速度慢、易陷入局部极小点等缺点,以遗传算法(GA)和模拟退火算法(SA)相结合的方式即遗传-模拟退火(GSA)算法对网络权值进行优化。用该方法预测滑坡位移获得了较好的效果(In this paper, a prediction model based on forward feedback propagation (BP) neural network is proposed for the complex problem of landslide prediction. The nonlinear relationship between input and output of landslide system is described. In order to overcome the shortcomings of BP network, such as slow convergence speed and easy to fall into local minima, genetic algorithm (GA) and simulated annealing algorithm (SA) are combined to optimize the network weight. The method can be used to predict the displacement of landslides)
