对美国轴承库的采集数据进行分析，通过功率谱等变换判断出是否发生故障，发生什么故障(American Bearing collected data database is analyzed by the power spectrum converting determines whether a fault occurs, a fault occurs it)

FDTD仿真，空气和玻璃界面的折射现象，可以观察到电磁波的折射现象。(A source of electric field is defined at the top edge of the spatial domain,(in glass) on the left half, which is a hard sinusoidal source, in that it does not change its value due to interference from external fields i.e in other words,the source is a perfect electric conductor. )

利用matlab针对图像进行马氏距离计算 ,小波包分析提取振动信号中的特征频率，随机调制信号下的模拟ppm。( Using matlab to calculate the Mahalanobis distance for the image, Wavelet packet analysis to extract vibration signal characteristic frequency, Random ppm modulated analog signal unde.)

Comparison of the performances of the LS and the MMSE channel estimators for a 64 sub carrier OFDM system based on the parameter of Mean square error

说明：  五点三次平滑法可用作时域和频域信号平滑处理。对时域作用是减少混入振动信号中的高频随机噪声。对频域是能使谱曲线光滑。(Three five-point smoothing method can be used as time domain and frequency domain signal smoothing. Effect on the time domain vibration signals to reduce high-frequency mixed with random noise. On the frequency domain is the spectral curve can smooth.)
