High frequency wave packets for the Schr\"odinger equation and its numerical approximations [PDF]

open access: yes, 2010
We build Gaussian wave packets for the linear Schr\"odinger equation and its finite difference space semi-discretization and illustrate the lack of uniform dispersive properties of the numerical solutions as established in Ignat, Zuazua, Numerical ...

Asymptotic Preserving numerical schemes for multiscale parabolic problems [PDF]

open access: yes, 2015
We consider a class of multiscale parabolic problems with diffusion coefficients oscillating in space at a possibly small scale $\varepsilon$. Numerical homogenization methods are popular for such problems, because they capture efficiently the asymptotic

Zn sorption on Ca-illite and Ca-smectite: experiment and modelling [PDF]

open access: yesE3S Web of Conferences, 2019
To predict Zn behaviour in soil, the retention properties of clay minerals plays a relevant role. In a continental environment, Ca is the main cation in solution.

Experimental data about mechanical behaviour during compression tests for various matted fibres [PDF]

open access: yes, 2005
A specific experimental device has been set up to test compressive mechanical behaviour of an assembly of fibres. Simple compression, as well as cyclic loading experiments and relaxation tests were performed. The experimental set up also allows to record
