this paper presents the application of the matching pursuit method to model synchronous generator. this method is useful for online analysis. in the proposed method, the field voltage is considered as input signal, while the terminal voltage and active power of the generator are output signals. usually, the difference equation with a second degree polynomial structure is used to estimate the co...

This paper presents a new characterization of musical signals which may lead to better understanding about how such signals are perceived. We first consider some signal analysis methods which facilitate measures of perceived qualities of music. More precisely, we consider a particular representation of signal energy on which to base a quantitative measure of sensory dissonance. After defining s...

most geologic changes have a seismic response but sometimes this is expressed only in certain spectral ranges hidden within the broadband data. spectral decomposition is one of the methods which can be utilized to help interpreting such cases. there are several time-frequency methods including: short-time fourier transform (stft), continuous wavelet transform (cwt), wigner-ville distribution (w...
