... become parameterization was performed with the use of the spectral subband centroid energy vectors (SSCEV) algorithm, which consistent when performed with the use of intelligent compresses the frequency spectrum and presents the results of systems capable of recognizing data patterns and classifying the AE energies in several frequency bands. Thus, it was them adequately [ ...
