9/7小波图像滤波，二维小波滤波快速分解重构(9/7 wavelet image filtering)

说明：  NFC smart card reader

说明：  本文介绍偏最小二乘回归分析的建模方法；通过例子从预测角度对所建立的回归模型进行比较(This paper introduces the modeling method of partial least squares regression analysis, and compares the regression models from the perspective of prediction through examples)

一些关于粒子群优化算法的matlab程序实现，里面有各种的PSO改进算法(Some matlab programs about particle swarm optimization algorithm are implemented. There are various PSO improved algorithms in them.)

说明：  用于在任何类型的六面体协调网格（结构化或非结构化）中模拟声学（流体）、弹性（固体）、耦合声学/弹性、多孔弹性或地震波传播。例如，它可以对地震后地震波在沉积盆地或任何其他区域地质模型中的传播进行建模。它也可用于非破坏性实验或海洋声学。(Used to simulate acoustic (fluid), elastic (solid), coupled acoustic / elastic, porous elastic or seismic wave propagation in any type of hexahedral coordination grid (structured or unstructured). For example, it can model the propagation of seismic waves in a sedimentary basin or any other regional geological model after an earthquake. It can also be used in non-destructive experiments or ocean acoustics.)

Delphi报表实例：导入导出Excel表格到指定的Delphi 数据网格中，将Excel.WorkSheets导入到Delphi中，也可导出内容到Excel中。

1. There are at least 10 nodes in the simulation and each node has at least two neighbors within its transmission area. 2. Every node periodically broadcasts a ”request” packet to its neighbors. Meantime, this node sets a timer with t time interval to wait for its neighbors ”re- sponse” packets. When receiving all responses from its neighbors during t, it prints ”success”; oth- erwise, it prints ”failure”. Assume that the broadcast periodical interval is bigger than t. 3. A neighbor that receives a ”request” packet, sends a ”response” packet after a random time τ , τ = random(0, 2t).(There are at least 10 nodes in the simulation and each node has at least two neighbors within its transmission area.
