The author studies the elliptic system of first-order strongly nonlinear differential equations of one complex variable \[ u_{\bar z} = \mu^1u_z + \mu^2\bar u_{\bar z} + f \equiv A(z,u,v),\quad v = u_{z} \] which is commonly used to describe diffusion and convective processes of heat and mass transfer in a fluid.

Fluctuations in Diffusion Processes in Microgravity
Annals of the New York Academy of Sciences, 2006Abstract: It has been shown recently that diffusion processes exhibit giant nonequilibrium fluctuations (NEFs). That is, the diffusing fronts display corrugations whose length scale ranges from the molecular to the macroscopic one. The amplitude of the NEF diverges following a power law behavior ∝ q−4 (where q is the wave vector).

Ergodicity of Diffusion Processes [PDF]
, 2017 In this talk, I will discuss ergodic properties of diffusion processes focusing on the rate of convergence of the marginals of the process to the invariant measure with respect to the total variation distance and Wasserstein distance. In particular, I will present sharp conditions in terms of the coefficients of the process (generator) ensuring sub ...

Image processing using diffusion processes
Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010We propose a new algorithm inspired by the properties of diffusion processes for image filtering. We show that purely nonlinear diffusion process ruled by Fisher equation allows contrast enhancement and noise filtering, but involves a blurry image. By contrast, anisotropic diffusion, described by Perona and Malik algorithm, allows noise filtering and ...

A Note on Diffusion Processes with Jumps
2018We focus on stochastic diffusion processes with jumps occurring at random times. After each jump the process is reset to a fixed state from which it restarts with a different dynamics. We analyze the transition probability density function, its moments and the first passage time density.

This paper is a summary of the flannel board presentation on how farm people accept new ideas. It is based on the findings of 35 research studies conducted during the past twenty years in various parts of the United States, including Illinois, Iowa, Missouri, Wisconsin, New Hampshire, New York, West Virginia, Kentucky, and Tennessee.1 The findings of ...
