Denoising Method Based on Spectral Subtraction in Time-Frequency Domain
Advances in Civil Engineering, 2021 In view of the key problem that a large amount of noise in seismic data can easily induce false anomalies and interpretation errors in seismic exploration, the time-frequency spectrum subtraction (TF-SS) method is adopted into data processing to reduce ...

A constrained-based optimization approach for seismic data recovery problems [PDF]
, 2014 Random and structured noise both affect seismic data, hiding the reflections of interest (primaries) that carry meaningful geophysical interpretation. When the structured noise is composed of multiple reflections, its adaptive cancellation is obtained ...

An SSI‐Informed Design for Tuned Mass Dampers With Small‐to‐Large Mass Ratios
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Tuned Mass Dampers (TMDs) are used to mitigate structural vibrations induced by seismic or wind excitation, by tuning the device to the system's dominant resonant frequencies. However, the TMD effectiveness can be undermined by soil‐structure interaction, which can lead to elongation of the vibration periods and to combined translational ...

Seismic random noise attenuation using modified wavelet thresholding
Annals of Geophysics, 2017 In seismic exploration, random noise deteriorates the quality of acquired data. This study analyzed existing denoising methods used in seismic exploration from the perspective of random noise. Wavelet thresholding offers a new approach to reducing random
