能够监控到本机Mysql产生最新的数据，用API接口发送到服务器。 程序采用Windows服务，开机便会自动运行，实时监控上传(It can monitor local Mysql to produce the latest data and send it to the server with API interface. The program uses Windows service, it will run automatically when it starts, and real-time monitor and upload.)

用Cplex求解一个仓库选址的问题，目标是使总成本最小。(a program using Cplex on C++ platform to solve a warehouse site selection problem to minimize total costs.)

说明：  GPS 整周模糊度求解的lambda方法，通过matlab仿真进行实现。(The lambda method of GPS ambiguity resolution is realized by MATLAB simulation.)

说明：  k均值聚类算法函数。利用k均值聚类方法对样本进行分类(K-means clustering algorithm function)

说明：  实现了一个直接扩频系统，使用BPSK作为调制解调方法。并比较白噪声AWGN及瑞利衰落(rayleigh fading)环境下，误码率的影响。(There are two files in the zip folder. bpsk_spread.m and jakesmodel.m Steps for simulation: 1] Run jakesmodel.m first 2] Then run bpsk_spread.m . 3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented 4] The resulting performance is stored in BER_awgn. 5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file. 6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable. 7] Run the simulation. To compare the perfromances of the receiver using DSSS plot the BER_awgn and BER_ray >>semilogy([1:8],BER_awgn(1:8), g* ) hold on semilogy([1:8],BER_ray(1:8), -.b* ) hold on grid on )
