假设在一个ad hoc网络中，移动节点的发射功率PTx总是恒定的。要发送数据的移动节点总是先监听信道，测量接收到的信号功率X，其中X= I + N, I为接收到的干扰，N是噪声。移动节点只有在X＜INThre时，才可以发射。式中，INThre为背景噪声门限。 在仿真中，我们规定每个移动节点的发射功率是常数，PTx = 1W；接收节点接收机的灵敏度Smin = -80 dBm；信号质量 min = 2 dB；系统的背景噪声门限INThre = 1.2e-10。 (Assuming in an ad hoc network, mobile node s transmission power is always constant PTX. To send data to the mobile node always monitor channel, measuring the received signal power X, which X = I+ N, I was received interference, N is the noise. Mobile node only when X <INThre when it is fired. Where, INThre threshold for background noise. In the simulation, we require that each mobile node s transmission power is constant, PTx = 1W receiver node receiver sensitivity Smin =-80 dBm signal quality )

MATLAB模拟人走路姿势，各个节点的选取和函数的调用是我们学习的很好例子(MATLAB simulation of human walking, each node of the selection and function calls is a good example of learning)

说明：  灰色模型，用于只有少数数据的情况，有良好的收敛性，简单有效(GM(1,1)model,be used to pretect data)

边缘是指图像中像素灰度有阶跃变化或屋顶状变化的那些像素的集合。学会并掌握使用matlab进行图像的边缘检测，设计用户界面实现上述功能。 实际问题： 1、采用matlab Guide设计图像界面，可以读入并显示图像，设计实现以下功能的菜单，点击相应的菜单（如radio button）在图像界面上可以显示相应的功能。 2 使用sobel检测算子； 3 使用prewitt检测算子； 4 使用canny检测算子； (Edge is refers to the image pixel has a step change in the collection of those pixels or roof shape change. Learn and master using matlab for image edge detection, design the user interface to realize the function. The real problem: 1, Guide design based on matlab image interface, can be read and displayed image, design and implement the following function menu, click on the corresponding menu (such as a radio button) in the image on the interface can display the corresponding function. 2 use the sobel detection operator 3 use prewitt detection operator 4 use the canny detection operator )

resistive and inductive load. simulation also demonstrate the role of free wheeling diode. Single phase pulse generator was developed to generate the pulses at required firing angle.
