用基本的粒子滤波算法，即SIR运行UNGM模型。通过UNGM模型显示SIR对于非线性系统的性能。(With the basic particle filter algorithm, that is, to run UNGM model of SIR. By UNGM model shows SIR for the non-linear system performance.)

图像隐藏和数字水印。采用在空域隐藏，在每个象素的bit位的低位藏入图片。采用在DCT系数上附加信息的方法进行。(image hiding and digital watermarking. Hidden in the airspace used in each pixel of the low bit-into the possession of photographs. Using the DCT coefficient Additional information on the methods.)

一堆沙子的横截面，可以使用 Margolus 型邻居仿真，但运动规则不同。 规则： 元胞有 2 个状态。状态= 0 是空的，状态= 1 代表沙子。 在任何时间步长，一个粒子，可以在2x2 块中向着底部运动。可能运动如下 所示。墙壁和底部将阻止粒子继续运动。 为了让该运动略有随机性，我亦补充说一项规则，有时处于下落状态的两个元胞还旋转，直到所有的动作都完成。(Cross-section of a pile of sand, you can type using the Margolus neighborhood simulation, but the movement rules are different. Rules: There are two cellular states. State = 0 is empty, state = 1 for sand. At any time step, a particle can be in the 2x2 block toward the bottom of the movement. May exercise the following. Walls and bottom to prevent the particles continue to campaign. To make the campaign a little random, I also added a rule, sometimes in the falling state of the two cell also rotate until all actions are completed.)
