关于多选择背包的很好的文章，提供了各种设计思路(Multiple Choice Knapsack Problem Example of planning choice in transportation )

comments and thoughts

说明：  matlab代码，轴承特征提取，包括rms、最大幅值、峰值因子、绝对平均值、平均值、峭度、脉冲因子、裕度因子、能量，小波包、经典模态分解等特征(Matlab code, bearing feature extraction, including rms, maximum amplitude, crest factor, absolute mean, mean, kurtosis, pulse factor, margin factor, energy, etc.)

这是一个低通抽样定理，例题中包括了低通信号的波形，抽样速率为4Hz的抽样信号，抽样序列恢复出原始信号(This is a low-pass sampling theorem, examples included in the lowpass signal waveform, the sampling rate is 4Hz sampling signal to recover the original signal sample sequence)

卡尔曼滤波的国外论文，详细讲述了卡尔曼滤波的提出背景，以及应用场合，是卡尔曼那滤波的经典论文(kalman filter )

分数阶傅里叶变换的二维峰值搜索，针对线性调频信号的峰值能进行很好估计(D peak search Fractional Fourier transform for the peak chirp signal can be well estimated)

说明：  脉内线性调频、脉间频率步进信号的模糊函数(Linear FM pulse, pulse frequency step signal ambiguity function)

给出了关于卡尔曼滤波器的详细说明，是新人学习必备(Given on a detailed description of Kalman filter is a new learning required)
