计算流体力学里常用的simple算法实现，尤其对不可压缩流体数值模拟。以库埃特流为例(Computational fluid dynamics in the simple algorithm used to achieve, especially for numerical simulation of incompressible fluid. Couette flow as an example to)

清华大学的教学书记，希望对大家 由帮助。歇谢谢(book tsinghua)

OFDM调制模型，采用16QAM方式，并介绍了一种基于这种调制方式下的OFDM载波同步方法。每一步都有英文解释。(OFDM modulation model, using 16QAM mode and introduced an approach based on this modulation method under the OFDM carrier synchronization. English to explain every step.)

强大机器人编码程序，设计移动有很大帮助这领域发展(powerful robot motion is really and powerful programming to develop this fileds)

说明：  该程序用来检验monte carlo随机数的分布是否满足随机性要求。包括独立性检验、均匀性检验和参数检验。(procedures used to test the Monte Carlo random number distribution to satisfy the requirements randomness. Including the independence test, uniform test parameters and test.)

当信噪比较大时，采用广义最小二乘法可能会出现多个局部收敛点，解决这个问题的方法可用多级最小二乘法，一般来说多级最小二乘法包含三级辨识过程。利用输入输出数据，通过多级最小二乘法，可分别求的辅助模型，过程模型和噪声模型的参数估计值。在高噪声的情况下，多级最小二乘法明显优于广义最小二乘法，其收敛点唯一。(When the signal noise ratio (SNR), and by use of the generalized least squares method may appear more local convergence point, the way of solving this problem can be used multistage least squares method, and generally multistage least squares method includes three identification process. Using input/output data, through the multistage least squares, respectively for the auxiliary model, process model and noise model parameter estimation. In the high noise, multistage least squares method is obviously superior to the generalized least squares method, and its convergence point only.)
