Aion Item Templates for Aion 1.9

本代码用于模拟二维桁架结构在外载激励作用下、存在动力吸振器的情况下的响应情况，完全原创，只有一个m文件用于生成桁架振动动画的avi文件，其余三个函数用于辅助生成具体桁架结构的参数以及辅助计算。外载荷频率、动力吸振器固有频率可以通过改变代码中的变量来控制。(This code is used to simulate the two-dimensional truss structure as set out under the incentive, there are circumstances in response to the situation under dynamic vibration absorber, and completely original, only one file is used to generate m truss vibration animation avi files, the remaining three functions are used to assist generate specific parameters and supporting calculations truss structure. External load frequency, dynamic vibration absorber natural frequency can be controlled by changing the variables in the code.)

MATLAB程序，可以计算稳态噪声的响度、尖锐度等。(Calculating the loudness, sharpness of steady noise)

说明：  二维图像加噪声，通过小波变换分解，压缩，实现图像重构(Two-dimensional image plus noise, through the Wavelet decomposition, compression, Image reconstruction)

1)football.m简单地以阵列形式显示一副图； 2）pre.m是心音信号过滤归一化预处理的过程； 3）wavlet.m是用db6小波进行信号的分解和重构，且求包络能量函数； 4）path.m是利用KKT条件的路径跟踪法，用于求解二次规划问题； 5）LRmmse是MIMO通信中常用检测方法，结合了最小均方误差准则和格基规约的知识。(1) football.m simply displays a graph in an array 2) pre.m is the process of normalized preprocessing of heart sound signal filtering 3) wavlet.m is a db6 wavelet for signal decomposition and reconstruction, and to find the envelope energy function 4) path.m is the path tracking method using KKT condition, which is used to solve the quadratic programming problem. 5) LRmmse is a commonly used detection method in MIMO communication, combining the knowledge of minimum mean square error criterion and lattice protocol.)
