Calibrated, robust, and physically consistent uncertainty quantification in deep-learning surface-wave shallow shear-velocity inversion

The shallow shear-wave velocity structure obtained from surface-wave dispersion inversion is essential for seismic site characterization; however, deterministic inversion provides only point estimates without uncertainty, while existing probabilistic approaches often lack coverage calibration, systematic robustness e...

Benchmarking time-domain, frequency-domain, and subspace estimators for ambient-vibration modal damping identification

The damping ratio is the modal parameter that is hardest to identify reliably and exhibits the largest scatter in structural health monitoring and operational modal analysis; a trustworthy baseline relies on multi-estimator cross-validation and uncertainty quantification. Measured damping data for high-rise reinforced-...
