We introduce a nondiagonal seismic denoising method based on the continuous wavelet
transform with hybrid block thresholding (BT). Parameters for the BT step are adaptively …

The World Health Organization has declared COVID-19 a pandemic. The demand for
devices or systems to diagnose and track COVID-19 infections noninvasively not only in …

Seismograms are the vital sources of information in seismic engineering. But, these records
are always contaminated with noise which has to be removed before using them in seismic …

Obtaining reliable empirical Green's functions (EGFs) from ambient noise by seismic
interferometry requires homogeneously distributed noise sources. However, it is difficult to …

SASW method is a nondestructive in situ testing method that is used to determine the
dynamic properties of soil sites and pavement systems. Phase information and dispersion …

Wavelet based denoising of the observed non stationary time series earthquake loading has
become an important process in seismic analysis. The process of denoising ensures a noise …

One of commonest problems in electrocardiogram (ECG) signal processing is denoising. In
this paper a denoising technique based on discrete wavelet transform (DWT) has been …

A estimativa da wavelet da fonte a partir de dados sísmicos é uma tarefa importante no
esforço de imageamento da subsuperfície. Neste estudo pretendemos testar uma …

Parametric filters are widely used to determine arrival time of P wave. The disadvantage of
its method is phase shifting occurred on filtered seismic signal. Consequently, an arrival time …

In bayesian wavelet shrinkage, the already proposed priors to wavelet coefficients are
assumed to be symmetric around zero. Although this assumption is reasonable in many …
