Gaussian derivative wavelet propagation in a single scattering bubbly water beyond resonance frequency
Autor: Le Gonidec, Yves
Acoustic pulses transmitted across air bubbles in water are usually analyzed in the ν frequency domain to determine attenuation and phase velocity for comparison with effective models. In the present work, acoustic experiments performed beyond the b

Robust experimental study of avalanche precursory events based on reproducible cycles of grain packing destabilizations
Autor: Oger Luc, Delannay Renaud, Le Gonidec Yves
Publikováno v: EPJ Web of Conferences, Vol 249, p 03023 (2021)
Quasi-periodic collective displacements of grains at the free surface of a tilted grain packing constitute precursors of granular avalanches. Laboratory experiments are commonly performed by slowly tilting the packing from 0° to the maximal stabilit

International audience; A varying Q factor with depth induces modifications of seismic wave features due to anelastic propagation but also reflections at the discontinuities. Standard signal analysis methods often neglect the reflection contribution
