The S-wave velocity of the shallow subsurface can be inferred from shallow-seismic
Rayleigh waves. Traditionally, the dispersion curves of the Rayleigh waves are inverted to …

The detection of delamination and rebar debonding is among the most frequently
encountered issues for inspecting concrete for quality control and assurance. This paper …

We have developed an application of 2D time-domain waveform tomography for detection of
embedded sinkholes and anomalies. The measured seismic surface wavefields were …

Elastic full waveform inversion (EFWI) aims to reduce the misfit between recorded and
modelled multicomponent seismic data for deducing a detailed model of elastic parameters …

Elastic full-waveform inversion (FWI) updates model parameters by minimizing the residuals
of the P-and S-wavefields, resulting in more local minima and serious nonlinearity. In …

This paper proposes an improvement on the scattering-integral (SI) approach for acoustic
frequency-domain full waveform inversion (FWI) based on the individual Born kernels. The …

In order to account for the effects of elastic wave propagation in marine seismic data, we
develop a waveform inversion algorithm for acoustic‐elastic media based on a frequency …

Site characterization for design of deep foundations is very crucial, as unanticipated site
conditions still represent significant problems and disputes occur during construction …
