WebS transform (ST) proposed by Stockwell et al. is the unique transform that provides frequency-dependent resolution while maintaining a direct relationship with the Fourier spectrum. This feature is very important for applications. However, the ST can't work well for seismic data analysis since its basic wavelet is not appropriate. WebJun 3, 2024 · According to the fact that high frequency will be abnormally attenuated when seismic signals travel across reservoirs, a new method, which is named high-precision …

WebThe enormous popularity and broad usefulness of the hypergeometric function 2 F 1 and the generalized hypergeometric functions p F q p, q ∈ N 0 of one variable have inspired and stimulated a large number of researchers to introduce and investigate hypergeometric functions of two or more variables (see, e.g., [1,5,11,16,19,20]).A serious, significant, … WebAug 31, 2014 · A generalized S transform based on energy normalized windows is presented, which avoids the weighting effect of existing S transform influenced by the time-frequency spectral energy. The transform can reflect the spectral energy distribution of different frequency components while maintaining the excellent time-frequency resolution. WebJun 19, 2024 · The generalized S transform, proposed by Stockwcllet, absorbs the advantages of short-time Fourier transform and wavelet transform (Stockwcll et al. 1996). Through the generalized S transform, the two-dimensional time–frequency spectrum with high resolution can be obtained. After the data selection, the inverse S transform is … simon shields lawyer
