摘要：

This paper reports the application of wavelet signal processing of Acoustic Emission data. The study is based on orthogonal Daubechies wavelets. The focus of the analysis is on feature/dimension reduction and cluster analysis. The parameters based on orthogonal wavelet coefficients are used to cluster the data. This approach is presented using the Acoustic Emission data generated from the box girder of a bridge.
