Different kinds of fractal cluster were simulated by using the diffusion limited aggregation (DLA) model in this paper. The interaction multiple electromagnetic scattering liner equation of fractal aggregate soot was present in shaped Gaussiam beam incident case. The localized approximation method was used to calculate the beam coefficients. And the mean-field approximation method was used to simplify...
Combining the aperture coupling theory and transmission line theory, this paper discusses the issue of the electromagnetic field penetration through apertures to a cavity and coupling to a two-wire transmission line in the cavity. On the apertures, based on the equivalence principle, equivalence sources are obtained by using the Galerkin's method. Then, by employing the so-called Agrawal coupling...
To solve the problem of query-by-example in multimedia audio data, we analyze the characteristics of wavelet multiresolution, wavelet packet transform and it’s best base, and propose a method for searching audio data using wavelet packet best base and wavelet multiresolution pyramidal algorithm. First, we preprocess 100 audio data files by transforming them into best base coefficient and wavelet coefficient...
