The passive structural health monitoring system is built based on the theory of acoustic emission in this paper. According to dispersion properties of the Lamb wave propagated in the thin materials, Morlet wavelet transform and energy wave crest are used to calculate the time delay among different sensors. Structural damage locations of glass fiber reinforced composites (GFRP) H60 and P60 are researched...
Based on the analysis of real-time data function of power plant and some current data compression methods, an integrated data compression scheme using process monitoring and lifting wavelet transform is proposed. In this method, the signal is first examined in order to find out the samples from abnormal states via process monitoring method. Then, the lifting wavelet transform is performed. As to signal...
