The inverse medium problem for Timoshenko beams and frames : damage detection and profile reconstruction in the time-domain
… multiplicity by means of either Tikhonov or Total Variation regularization. We report on numerical experiments using synthetic data that show satisfactory reconstruction of a variety of profiles, including smoothly and sharply varying profiles, as well as profiles exhibiting localized …

Numerical modeling, suppression, and imaging of elastic wave scattering by near-surface heterogeneities
… of near-surface heterogeneities on seismic wavefield scattering for better understanding of land seismic data, develop an effective approach to filter out the scattered noise from the seismic records to enhance the signal-to-noise ratio, and to accurately image and locate the near-surface …
