修复惠普笔记本升级bios导致的product information not valid(hp to fix product information not valid_hp notebook)

说明：  用于计算多普勒频移的函数，MATLAB语言，挺好用。(The function for calculating Doppler frequency shift, MATLAB language, is very useful.)

说明：  基于自适应滤波算法的通信系统中微弱信号检测程序(Weak Signal Detection Program in Communication System Based on Adaptive Filtering Algorithms)

说明：  对网上现有的产生m序列的线性反馈移位寄存器代码进行了修改，可以通过输入本原多项式向量，生成相应m序列(The existing linear feedback shift register code for m-sequence generation on the Internet is modified. The corresponding m-sequence can be generated by inputting the primitive polynomial vector)

主要用于振动信号的频谱分析，用于判断信号中的故障频率(the fft analysis of the vibration signal)

说明：  思科为IEC61850行业标准实现的源码库，其中提供MMS、GOOSE/SV完整的服务和例程。(Sisco provides a source library for IEC61850 industry standard implementation, which provides complete services and routines for MMS, GOOSE/SV.)

叠前时间偏移代码，fortran格式，可以用于三维地震数据处理，可以在此基础上进一步完善其应用范伟。(Kirchhoff time migration code fortran version)

在本文中，我们设计，实施和实验性地评估可扩展定向多播（SDM）技术，以1）通过部分遍历码本树以每波束每客户端RSSI测量来训练接入点。培训平衡了收集足够数据以形成有效波束组的限制开销的目标。 2）利用可用的训练信息，设计了一种近似最小组播组数据传输时间的可扩展波束分组算法。(In this paper, we design, implement and experimentally evaluate scalable directional multicast (SDM) technology to train access points by partially traversing the codebook tree with RSSI measurements per beam per client. The training balanced the goal of collecting enough data to form the limiting cost for effective beam formation. 2) Using available training information, a scalable beam grouping algorithm with approximate minimum multicast group data transmission time is designed.)

说明：  实现激光打标机二次开发，能够成功实现初始化的过程，但是需要将本程序放置到原EZCAD软件的文件夹内。(To realize the secondary development of laser marking machine, the initialization process can be realized successfully, but this program needs to be placed in the folder of the original ezcad software.)

说明：  The power electronic drive controls the rate of induction motor by V/F method.
