　计算机人脸识别技术( Face Reocgnition)就利用计算机分析人脸图像,从中提取出有效的识别信息,用来辨认身份的一门技术。[ 1 ]即对已知人脸进行标准化处理后,通过某种方法和数据库中的人脸样本进行匹配,寻找库中对应人脸及该人脸相关信息。人脸自动识别系统有两个主要技术环节,一是人脸定位,即从输入图像中找到人脸存在的位置,将人脸从背景中分割出来,二是对标准化后的人脸图像进行特征提取和识别。本文中介绍的PCA (特征脸)方法就是一种常用的人脸 特征提取方法。(Computer Face Recognition Technology (Face Reocgnition) on the use of computer analysis of facial image, to extract the valid identification information used to identify the status of a technology. [1] that is known to standardize treatment of face, through a method and a database of face samples for matching, search library, the corresponding face and the face-related information. Automatic face recognition system has two main technical aspects, first, face location, that is, from the input image to find the location of the face there, the faces will be split out from the background, the second is, the standard features of face images extraction and recognition. Described in this paper PCA (Eigenfaces) method is a common facial feature extraction method.)

线性系统频域理论的实现 包括多项式，多项式矩阵，系统的矩阵分式描述，多项式矩阵描述，系统实现等。 其中多项式描述尚未完善。(frequency domain linear systems theory, including the realization of polynomials, polynomial matrix, the matrix fraction description, polynomial matrix description of system implementation. Description polynomial which is not yet perfect.)

本代码是利用dwt小波分析，实现了对音频加入灰度水印的源代码，可直接运行，生成两个音乐文件，一个是嵌入声音后的，另外一个是噪声文件。(This code is the use of wavelet analysis dwt, the realization of audio into grayscale watermark source code can be run directly, generates two music files, one after the embedded voice, the other is the noise file.)

A Self-Tuning Analog Proportional-Integral-Derivative (PID) Controller

基于matlab的zoeppritz反演程序,可用于AVO反演( This function computes the particle displacement reflection and transmission coefficients (the relative displacement amplitudes) for a solid-solid interface, a liquid-solid interface, a solid-liquid interface, and a liquid-liquid interface.)

说明：  基础隔震结构简化成串联多质点系计算动力响应，隔震支座采用Bouc-wen模型模拟，用Newmark逐步积分法计算。(Base isolation structure is simplified into a series multi-particle system dynamic response, isolators using Bouc-wen model simulation, calculated using the Newmark direct integration scheme.)
