Bridging hydraulic diffusivity from aquifer to particle-size scale: a study on loess sediments from southwest Hungary
(Taylor &Francis Ltd, 2015-02-01)
In situ megascale hydraulic diffusivities (D) of a confined loess aquifer were estimated at various scales (10 <= L <= 1500 m) by a finite difference model, and laboratory microscale diffusivities of a loess sample ...
Approximation of the effectiveness factor in catalytic pellets
(Elsevier Science Sa, 2003-08)
The 1D model proposed by Burghardt and Kubaczka [Chem. Eng. Proc. 35 (1996) 65] to approximate the behavior of 3D catalytic pellets has been recently found able to provide accurate results for evaluating effective reaction ...
An elementary proof of the uniqueness of invariant product measures for some infinite dimensional processes
(EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2002)
Consider an infinite dimensional diffusion process with state space T-Zd, where T is the circle, and defined by an infinitesimal generator L which acts on local functions f as Lf(eta) = Sigma(iepsilonZ)(d) (a(i)(2)(etai))/2 ...
