平面上的超声速流(有粘性边界层和激波)
应用背景程序求解完全的二维N-S方程,考虑了粘性和导热。当来流Mach数为4时,计算结果与书上的结果一致,然而,我的程序不能计算Mach数为25的情况(即书中提供的另一种工况的比较结果),经过仔细检查,我认为自己的程序没毛病,可能是书中求解步长的公式给错了(eq.(10.16) in p.457),还望大家帮助检查一下。最后还要说明的是,该章在指导你写程序时,书上有些关键地方有印刷错误,会误导你,一定要小心。参考文献:Chapter 10, Computational Fluid Dynamics, The Basics with Applications, John D.

k-means的java实现
应用背景Implement k-means clustering on a training data set to predict classification values of a test data set.关键技术The experiment intended to classify test data values using the data
mining strategy known as k-means clustering.
The 6 variables in the training data are used to plot the data and
centroids are placed to locate clumps of the 255, classified training
data. Once located, a classification value can be assigned to the 100,
test data.

OFDM 仿真程序
OFDM仿真程序OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术,实际上OFDM是MCM Multi-CarrierModulation,多载波调制的一种。其主要思想是:将信道分成若干正交子信道,将高速数据信号转换成并行的低速子数据流,调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开,这样可以减少子信道之间的相互干扰 ICI 。实现多载波传输
