Imaging method for interface rheological characterization
Nicolas Abi Chebel, Olivier Masbernat, Frédéric Risso +4
The present work investigates free damped oscillations of an oil drop in water after its release from a capillary tube. Both pure heptane drops and diluted crude oil drops are cons…
Local time steps for a finite volume scheme
Isabelle Faille, Frédéric Nataf, Françoise Willien +1
We present a strategy for solving time-dependent problems on grids with local refinements in time using different time steps in different regions of space. We discuss and analyze t…
Local Polynomial Estimation for Sensitivity Analysis on Models With Correlated Inputs
Sébastien Da Veiga, François Wahl, Fabrice Gamboa
Sensitivity indices when the inputs of a model are not independent are estimated by local polynomial techniques. Two original estimators based on local polynomial smoothers are pro…
Perturbations of the seismic reflectivity of a fluid-saturated depth-dependent poro-elastic medium
Louis De Barros, M. Dietrich
Analytical formulas are derived to compute the first-order effects produced by plane inhomogeneities on the point source seismic response of a fluid-filled stratified porous medium…
