产生北斗b1频点信号

说明：  可以用其计算信噪比，只需要输入原信号和带噪声信号即可。还有一段EMD分解程序(It can be used to calculate the signal-to-noise ratio, only need to input the original signal and the signal with noise.)

Java写的RPG游戏开源源码实例，通过这个PRG游戏，你可学习到NPC的碰撞检测、人脸表情动画、人物移动坐标、线程进入阻塞状态、游戏装载、地图坐标设计、地图边界算法等技巧，本PRG游戏中E2字体放置14个,手机模拟器用18个为满。

拥有倾角环和位置环的PID控制倒立摆，每个倒立摆不同，所以参数未测定，需自行测定(PID control inverted pendulum with inclination ring and position ring, each inverted pendulum is different, so the parameters are not determined, and need to be determined by oneself.)

基于互功率谱的时延估计，包括广义互相关函数GCC时延估计，已调制信号计算其普相关密度。( Based on the time delay estimation of power spectrum, Including the generalized cross-correlation function GCC time delay estimation, Modulated signals to calculate its density Pu-related.)

基于vue+element的电商后台管理系统，完整实现了整个流程。 该项目为前后端分离项目，搭建步骤具体参考后端项目传送门。(Based on Vue element, the whole process is realized. This project is a front-end and back-end separation project. It builds a portal with specific reference to the back-end project.)

说明：  天牛须优化算法及其对BP神经网络的优化。(The optimization algorithm and its application to BP neural network)

说明：  tugkqwrqfe deaf xgvx dfhr aff

n后问题，也适合八皇后问题，环境Vc6.0-n After the issue, is also suitable for the eight queens problem

说明：  data mining algorithm implementation

说明：  实现萤火虫算法，主要是优化算法，用于寻找多目标时的最优值，效果比,基于matlab平台搭建，在多个科研和工作方向使，供大家学习参考。(Firefly algorithm, mainly optimization algorithm, is used to find the optimal value of multi-objective, the effect ratio, based on MATLAB platform, in a number of scientific research and work directions, for everyone to learn reference.)
