From the diffusion coefficient to the diffusion tensor [PDF]

open access: yesNMR in Biomedicine, 2002
AbstractWith diffusion tensor MRI one has access to the organization in space of tissue microstructural components. This outstanding potential adds, however, another layer of complexity to the diffusion MRI data acquisition and analysis processes. Over the last few years many articles have been published dealing with those matters.

Controlled Laboratory Experiments on Radon Diffusion Coefficient

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019
Radon which occurs inuranium decay series is a noble gas and it moves from the deeper layers of theearth crust to the atmosphere. Formation of the radon gas in the Earth's crustand its migration to atmosphere are quite complex process because of too ...

Moisture Diffusion Coefficient of Concrete under Different Conditions

open access: yesBuildings, 2023
Humidity change in concrete is the leading cause of concrete shrinkage. Moreover, the moisture diffusion coefficient of concrete is an essential parameter for assessing and predicting the internal moisture content of concrete. However, there is a lack of

Diffusive Transport in Periodic Potentials: Underdamped Dynamics [PDF]

open access: yes, 2008
In this paper we present a systematic and rigorous method for calculating the diffusion tensor for a Brownian particle moving in a periodic potential which is valid in arbitrary dimensions and for all values of the dissipation.

Surface diffusion coefficients for room acoustics : free-field measures [PDF]

open access: yes, 2000
A surface diffusion coefficient is needed in room acoustics to enable the quality of diffusing surfaces to be evaluated. It may also facilitate more accurate geometric room acoustic models.

Generalized Exclusion Processes: Transport Coefficients [PDF]

open access: yes, 2014
A class of generalized exclusion processes parametrized by the maximal occupancy, $k\geq 1$, is investigated. For these processes with symmetric nearest-neighbor hopping, we compute the diffusion coefficient and show that it is independent on the spatial
