Implementation of a rule using a Groovy script.

mathematica code for gaussian horn design. It can give the exact shape of gaussian for specific material, especially helpful for ultrasonic horn design.

利用tukey和barlett方法对随机信号的功率谱进行估计。迭代方法来判断性能(Tukey and the use of random signal barlett method to estimate the power spectrum. Iterative method to determine the performance of)

时频分析工具箱,需要的人可以试试,还不错(time-frequency analysis toolkit, the people can try out, quite good)

：自准直仪是比较常用的测角仪器，其原理是检测激光形成的图像光斑的中心之间的距离，通过 ) 个中 心的横纵坐标差来计算物体偏离的角度 ’ 利用迭代阈值和图像分割等方法将光斑图像进行预处理，然后将得到 的图像分别用重心法、圆拟合法和匹配法进行中心定位，并最终进行偏离角度的测定 ’ 文中介绍了所使用的几 种方法，并进行了仿真比较，结果表明，圆拟合法更有优势 ’ (: Is more commonly used since the collimator angle measuring instrument, the principle is to detect the distance between the center of the laser spot image formed by a) a horizontal and vertical coordinates of the center differential to calculate the deviation angle of the object ' iterative threshold and image method of segmentation, such as the spot image preprocessing, and then the resulting image with the center of gravity method, respectively, round contemplated legitimate and matching method center position, and eventually for the Determination of the deviation angle of ' paper describes the use of several methods, and simulation comparison, the results show that the circle fitting more advantageous' )

：主要介绍m序列、Gold序列、Kasami序列和JPL序列的生成原理及其MATLAB的实现，并介绍如何用MATLAB中 Simullnk对其进行硬件仿真，给出了相应自相关和互相关结果。(: The main introduction m sequence, Gold sequences, Kasami sequences and sequences generated JPL principle and the realization of MATLAB, and introduce how to use MATLAB in their Simullnk hardware simulation, the corresponding auto-correlation and cross-correlation results.)

K-mean均值算法是给定类的个数K，将N个对象分到K个类中去， 使得类内对象之间的相似性最大，而类 之间的相似性最小。 Kmean处理图像的matlab文件 (K-mean algorithm is given class means the number of K, K to N objects assigned to a class, making class similarity between objects within the maximum, while the similarity between class minimum. Image processing matlab file Kmean)

说明：  这是个关于图像遗传算法分割的源程序，在matlab上实现(This is a genetic algorithm on the image segmentation of the source, to achieve in matlab)
