绘制出齿轮网格，计算出齿轮应力，并画出两齿轮三维接触图。(Drawing out the gear mesh, calculate the gear stress, and draw two-dimensional contact map gear.)

A commonly used control device called a programmable logic controller, or a PLC, is used to read a set of digital and analog inputs, apply a set of logic statements, and generate a set of analog and digital outputs. Using the example in the previous paragraph, the room temperature would be an input to the PLC. The logical statements would compare the setpoint to the input temperature and determine whether more or less heating was necessary to keep the temperature constant. A PLC output would then either open or close the hot water valve, an incremental amount, depending on whether more or less hot water was needed. Larger more complex systems can be controlled by a Distributed Control System (DCS) or SCADA system.

pca matlab 人脸识别，靠，怎么上传个文件还这么烦，我倒！我晕！(face recognition pca)

在matlab环境下面编程，最好使用2012版本及其以上，完成利用matlab软件提供的图像处理函数来完成图像匹配，3D重建的工作。最后的效果图很好，由于是利用matlab自带的图片，所以压缩文件中无图片，直接打开m文件就可以运行！(Below programming in matlab environment, it is best to use 2012 version and above, using matlab software provides complete image processing function to complete the image matching, 3D reconstruction work. The final renderings good, as is the use of matlab comes with a picture, so the compressed file without pictures, you can directly open the m-file to run!)

此程序是OFDM的循环谱计算，希望对大家有用，(this procedure is the cycle OFDM spectrum, we hope to useful,)

this is the sobel programme which can help to do the segmentation and clustering

说明：  卡尔曼滤波器的仿真模型图，非常好用，大家可以试一试(Simulation Model Chart of Kalman Filter)
