Diffusion Tests for Chloride in Concrete Using Wind Tunnel Test
MATEC Web of Conferences, 2017 Diffusion coefficient of chloride in concrete is a predominant factor in chloride penetration into concrete. Two types of diffusion coefficient models are examined here: mean diffusion coefficient D, time-dependent diffusion coefficient D(t).

Double crystal x-ray diffraction simulations of diffusion in semiconductor microstructures [PDF]
, 1998 Diffusion in group IV, III-V and II-VI semiconductors is an interesting problem not only from a fundamental physics viewpoint but also in practical terms, since it could determine the useful lifetime of a device.

Self-diffusion in granular gases: Green-Kubo versus Chapman-Enskog
, 2005 We study the diffusion of tracers (self-diffusion) in a homogeneously cooling gas of dissipative particles, using the Green-Kubo relation and the Chapman-Enskog approach. The dissipative particle collisions are described by the coefficient of restitution

Dependence of chaotic diffusion on the size and position of holes
, 2012 A particle driven by deterministic chaos and moving in a spatially extended environment can exhibit normal diffusion, with its mean square displacement growing proportional to the time.

Time-varying diffusion characteristics of different gases in coal particles
International Journal of Mining Science and Technology, 2017 Based on the analytical solution of gas diffusion in spherical coal particles with a constant diffusion coefficient, a calculation method of time-varying diffusion coefficient is proposed by constructing objective function.

Testing the Diffusion Coefficient [PDF]
, 2002 In mathematical finance diffusion models are widely used and a variety of different parametric models for the drift and diffusion coefficient coexist in the literature. Since derivative prices depend on the particular parametric model of the diffusion coefficient function of the underlying, a misspecification of this function leads to misspecified ...

Total variation regularization of multi-material topology optimization [PDF]
, 2018 This work is concerned with the determination of the diffusion coefficient from distributed data of the state. This problem is related to homogenization theory on the one hand and to regularization theory on the other hand.
