33节点灵敏度计算

悬臂梁MATLAB有限元算例带详细注释的这个算是半原创吧。师哥写的(MATLAB finite element cantilever beam with a detailed example of this note it is semi-original. Writing the师哥)

对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印(Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). according to this embedding binary image and resume its embedded watermark from the watermark signal by the Blind detection)

说明：  ERA算法，通过MATLAB实现，进行模态分析(ERA program,realised by MATLAB for modal analysis)

电力系统暂态稳定程序，可以进行暂态稳定计算,外文资料里面的源代码，本科毕设要求参见标准测试模型。( Power System Transient Stability Program, can be transient stability, Foreign materials inside the source code, Undergraduate complete set requirements refer to the standard test models.)

发送CW编码脉冲，进行FSK编码，用自适应滤波器进行译码，经过仿真验证(CW sending coded pulses, FSK encoding and decoding using adaptive filters, through simulation)

对仿真信号进行时频分析，单峰检测，脊线提取，脊线拟合，计算脊线波动方差，从而判断信号类别。本次仿真采用的是线性调频信号，对其他信号也具有适用性。对仿真信号进行时频分析，单峰检测，脊线提取，脊线拟合，计算脊线波动方差，从而判断信号类别。(The time-frequency analysis of the simulation signal, unimodal detection, ridge line extraction, ridge line fitting, fluctuation variance calculation ridge line, to determine the signal classification.USES a linear frequency modulation signal, the simulation also has the applicability for other signals.The time-frequency analysis of the simulation signal, unimodal detection, ridge line extraction, ridge line fitting, fluctuation variance calculation ridge line, to determine the signal classification.)

说明：  我们知道，小波变换的一级分解过程是，原始信号分别进行低通、高通滤波，再分别进行二元下抽样，就得到低频、高频（也称为平均、细节）两部分系数；而多级分解则是对上一级分解得到的低频系数再进行小波分解，是一个递归过程。以下是一维小波分解的程序. (We know that a wavelet transform decomposition process is that the original signal were low-pass, high pass filter, and then carried out under the binary sample, we obtained low-frequency, high-frequency (also known as the average, details) coefficient of two parts and Multi-level decomposition is a decomposition of the previous low-frequency coefficients to be further wavelet decomposition is a recursive process. Following is a one-dimensional wavelet decomposition process.)
