利用Duhamel求解elcentro地震波作用下的地震加速度反应谱

说明：  用卡尔曼滤波方法预测目标轨迹，能够估计目标下一时刻的位置信息(Prediction of Target Trajectory by Kalman Filter)

集中质量串联模型，在El-centro地震波作用下的时程分析，并分析了隔震与非隔震支座下的顶层位移、速度、加速度的对比情况(The time series analysis of the concentrated mass series model under the action of El-centro seismic wave is carried out, and the comparison of the top displacement, velocity and acceleration under the condition of isolation and non isolation is analyzed.)

说明：  三相并网逆变器，有电压环和电流环双环控制，电流环参考值有功率控制(Three-phase grid-connected inverter with voltage control loop and current loop double loop, current loop power control reference values)

多传感器多目标数据融合的ＩＭＭ＿ＭＳＰＤＡ关联算法(IMMMSPDA association algorithm for multi sensor multi target data fusion)

说明：  关于小波包分解和小波包能量熵的算例，可直接运行。(Examples of wavelet packet decomposition and wavelet packet energy entropy.)

Package consists of 3 codes. First,to Print huffman decoding tree given.Second, to find top level view of a tree. Third, A reviewer rates the two challenges, awarding pointsfor three categories.We define the rating for two person s challenge to be the triplets .Your task is to find their comparison scores by comparing the triplets. If first digit of triplets is greater for person A, then the person A is awarded 1 point, else person B, and if equal, no one gets points.Given the triplets, compare the two challenges and print their respective comparison points.
