Journal diffusion factors – a measure of diffusion? [PDF]

open access: yesAslib Proceedings, 2004
This paper shows that the measure of diffusion introduced by Ian Rowlands called the journal diffusion factor (JDF) is highly negatively correlated with the number of citations, leading highly cited journals to get a low JDF, whereas less cited journals get a high JDF.

Reaction-diffusion processes with nonlinear diffusion [PDF]

open access: yesPhysical Review E, 2012
We study reaction-diffusion processes with concentration-dependent diffusivity. First, we determine the decay of the concentration in the single-species and two-species diffusion-controlled annihilation processes. We then consider two natural inhomogeneous realizations.

Two-Dimensional Rotating Stall Analysis in a Wide Vaneless Diffuser

open access: yesInternational Journal of Rotating Machinery, 2006
We report a numerical study on the vaneless diffuser core flow instability in centrifugal compressors. The analysis is performed for the purpose of better understanding of the rotating stall flow mechanism in radial vaneless diffusers. Since the analysis

Diffusion nets

open access: yesApplied and Computational Harmonic Analysis, 2019
Non-linear manifold learning enables high-dimensional data analysis, but requires out-of-sample-extension methods to process new data points. In this paper, we propose a manifold learning algorithm based on deep learning to create an encoder, which maps a high-dimensional dataset and its low-dimensional embedding, and a decoder, which takes the ...
