基于newmark方法的机床主轴传动系统工具包，可以分析求解传动系统、位移、速度、加速度响应(Methods based newmark spindle drive kit can analyze solving transmission, displacement, velocity and acceleration response)

该协议是LEACH的改进，思想是：为了延长网络的生命周期，节点只需要和她们最近的邻居之间进行通信。节点与汇聚点间的通信过程是轮流进行的，当所有节点都与汇聚点通信后，节点间再进行新一回合的轮流进行的。由于这种轮流通信机制使得能量消耗能够统一的分布到每个节点上，因此降低了整个传输所需要消耗的能量。(The agreement is LEACH improvement idea is: To prolong the network lifetime, and between nodes only need to communicate with their nearest neighbors. Communication process between the node and the focal point is in turn carried out when all the nodes are associated with the convergence point communication between nodes then turns a new round of. Due to this rotation so that the energy consumption of the communication system on each node to the uniform distribution, thus reducing the energy consumption required for the transmission.)

说明：  使用恒模CMA算法盲均衡，面向的调制信号是8PSK信号(Blind equalization using CMA algorithm with constant modulus and 8PSK modulation)

IDW距离反比加权方法，权重选择为2，可根据需要自己改变(IDW inverse distance weighting, the weight chosen as 2, can be changed according to need their own)

超声仿真的代码，matlab的，对于阵元的发射接收的例子，是很好的学习资料。改代码依附于丹麦理工的fieldtwo，可以参考user guide进行仿真。里面是文本格式的，打开转成.m文件即可(Of ultrasound simulation code, matlab example for the launch of the array element receives a good learning materials. Change the code attached to Danish Polytechnic fieldtwo, can refer to the user guide Simulation)

说明：  这是用MATLAB写的一个RD算法的程序，不知道有人上传过没有，希望有用(This is used to write a MATLAB algorithm RD procedure, I do not know it was not uploaded, I hope useful)

视频监控，如果有东西经过监控区域就语音报警（something is intruding）(Video surveillance, if there is something on the voice alarm through the monitored area (something is intruding))

使用matlab编写改进的欧拉数值算法程序(the Euler numerical algorithm matlab prepared to improve)
