用K均值算法和C模糊算法对sonar数据和iris数据进行分类。 K均值算法是一种很常用的聚类算法，其基本思想是，通过迭代寻找K个聚类的一种划分方法，使得用这K个聚类的均值来代表各类样本是所得到的的总体误差最小。 模糊C均值（FCM）算法在K均值算法的基础上，用模糊子集代替确定子集，从而得到模糊的分类结果，即分类结果的模糊化。(Sonar data and iris data are classified by means of K mean algorithm and C fuzzy algorithm. The K mean algorithm is a very common clustering algorithm. Its basic idea is to find a partition method of K clustering by iteration, so that the average error of the mean of the K clustering is minimized. The fuzzy C mean (FCM) algorithm is based on the K mean algorithm. The fuzzy subset is replaced by the fuzzy subset, thus the fuzzy classification result is obtained, that is, the classification result is fuzzed.)

OFDM系统仿真，采用1024子载波，内含卷积编码，交织，QPSK调制，上、下采样滤波，信道估计等(OFDM system simulation, using 1024 subcarriers, including convolutional coding, interleaving, QPSK modulation, the upper and lower sampling filtering, channel estimation, etc.)

Earthquake Engineering and Structural Dynamics(You can input any number of stores by giving the mass, stiffness and damping values. Input the gamma and beta values which are related to Newmark Integration Mtd. Press Newmarks Integration button to input the values. Input the any number of storey that you expected to see the deflection for particular Earthquake. Press “Storey No” button to get that number. If you like only, you will input the period and press “Period” button. Finally press calculate button to see final results. Also you can see the both graphs in log scales also.(Please right click on the graph as shown above). You may see what type of analysis method is used. (Average acceleration relation ship or Linear variation of acceleration).)
