Numerical modeling of 1-D transient poroelastic waves in the low-frequency range
Guillaume Chiavassa, Bruno Lombard, Joël Piraux
Propagation of transient mechanical waves in porous media is numerically investigated in 1D. The framework is the linear Biot's model with frequency-independant coefficients. The c…
Control of test particle transport in a turbulent electrostatic model of the Scrape Off Layer
Guido Ciraolo, Philippe Ghendrih, Yanick Sarazin +4
The drift motion of charged test particle dynamics in the Scrape Off Layer (SOL)is analyzed to investigate a transport control strategy based on Hamiltonian…
Adaptive Importance Sampling in General Mixture Classes
Olivier Cappé, Randal Douc, Arnaud Guillin +2
In this paper, we propose an adaptive algorithm that iteratively updates both the weights and component parameters of a mixture importance sampling density so as to optimise the im…
Transportation-information inequalities for Markov processes
Arnaud Guillin, Christian Leonard, Liming Wu +1
In this paper, one investigates the following type of transportation-information inequalities: for all probability measures on some metric space…
On the role of step-flow advection during electromigration-induced step bunching
Matthieu Dufay, Thomas Frisch, Jean-Marc Debierre
We propose a one-dimensional model based on the Burton-Cabrera-Frank equations to describe the electromigration-induced step bunching instability on vicinal surfaces. The step drif…
