Sentence examples for by a diffusion coefficient from inspiring English sources
In contrast, there is no theoretical reason to include this time constraint in the BB method, as it a priori assumes purely diffusive movements characterised by a diffusion coefficient that remains constant for the whole tracking period.
This motion results from the thermal energy carried by diffusing molecules and it is characterized by a diffusion coefficient D that provides information about the behavior of the molecular motion which in turn depends on the characteristics of the medium in which the diffusion occurs.
The magnitude of the diffusive flux is proportional to concentration gradient multiplied by a diffusion coefficient.
This is characterized by a diffusion coefficient which increases with increasing active electron concentration.
Focusing the general approach for the description of the diffusion by a diffusion coefficient (see Eq. 2), it is obvious that an increased temperature leads to a higher diffusion coefficient, thus resulting into a thicker contamination layer on the CFRP-parts.
The diffusion process is governed by a diffusion coefficient and the geometric characteristics of the receptor such as the encounter radius.
At larger Nafion content, the agglomerate model can describe the curves only by assuming a diffusion coefficient 3 4 decades smaller than that of gases.
By calculating a diffusion coefficient from trajectories over a sliding window of 20 frames, we tracked changes in receptor mobility with ∼1 s time resolution.
We also found that the migration slowed down as it expanded, where the migration distance was well fitted by a certain curve proportional to the square root of the duration, suggesting that the propagation was limited by diffusion with a diffusion coefficient of about 104 m2 s−104
The measured properties have been used to determine a diffusion coefficient by classification standard of gas flow regime.
We conclude this section by presenting one particular choice of a diffusion coefficient and a Wiener process.
