Fractional-calculus diffusion equation [PDF]

open access: yesNonlinear Biomedical Physics, 2010
Sequel to the work on the quantization of nonconservative systems using fractional calculus and quantization of a system with Brownian motion, which aims to consider the dissipation effects in quantum-mechanical description of microscale systems.The canonical quantization of a system represented classically by one-dimensional Fick's law, and the ...

Influence of Various Irradiance Models and Their Combination on Simulation Results of Photovoltaic Systems

open access: yesEnergies, 2017
We analyze the output of various state-of-the-art irradiance models for photovoltaic systems. The models include two sun position algorithms, three types of input data time series, nine diffuse fraction models and five transposition models (for tilted ...

Fractional reaction-diffusion equation [PDF]

open access: yesThe Journal of Chemical Physics, 2003
A fractional reaction-diffusion equation is derived from a continuous time random walk model when the transport is dispersive. The exit from the encounter distance, which is described by the algebraic waiting time distribution of jump motion, interferes with the reaction at the encounter distance. Therefore, the reaction term has a memory effect.

A fractional diffusion random laser [PDF]

open access: yesScientific Reports, 2019
AbstractThe goal of this letter is to introduce the concept of a non-resonant fractional random laser. This is achieved by extending the classical Letokhov model of photon diffusion through disordered gain media to fractional differential operators in space and time.

The relationship between diffuse and total radiation at the Solar and Ozone Observatory in Hradec Králové

open access: yesMeteorologische Zeitschrift, 1996
The daily and monthly data of the total radiation are used for estimation of the relationship between diffuse and total radiation in Hradec Králové. Analyses were expressed in parameters with the use of the method of least squares and a "Robust Locally ...

Erdélyi-Kober fractional diffusion [PDF]

open access: yesFractional Calculus and Applied Analysis, 2011
The aim of this Short Note is to highlight that the {\it generalized grey Brownian motion} (ggBm) is an anomalous diffusion process driven by a fractional integral equation in the sense of Erdélyi-Kober, and for this reason here it is proposed to call such family of diffusive processes as {\it Erdélyi-Kober fractional diffusion}.
