THE DIFFUSION PROCESS [PDF]

open access: yesIncreasing Understanding of Public Problems and Policies, 1956
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 ...

Interpolation process between standard diffusion and fractional diffusion [PDF]

open access: yesAnnales de l'Institut Henri Poincaré, Probabilités et Statistiques, 2018
We consider a Hamiltonian lattice field model with two conserved quantities, energy and volume, perturbed by stochastic noise preserving the two previous quantities. It is known that this model displays anomalous diffusion of energy of fractional type due to the conservation of the volume [5, 3].

Graph Regularized Hierarchical Diffusion Process With Relevance Feedback for Medical Image Retrieval

open access: yesIEEE Access, 2021
Befitting from the interpretability and the capacity in capturing the underlying manifold structure, diffusion process (DP) has attracted increasing attention in the field of image retrieval.

Echoes and glimpses of a distant drum [PDF]

open access: yesOpuscula Mathematica, 2020
To what extent does the spectrum of the Laplacian operator on a domain \(D\) with prescribed boundary conditions determine its shape? This paper first retraces the history of this problem, then Kac's approach in terms of a diffusion process with ...

A solving method for two-dimensional homogeneous system of fuzzy fractional differential equations

open access: yesAIMS Mathematics, 2023
The purpose of this study is to extend and determine the analytical solution of a two-dimensional homogeneous system of fuzzy linear fractional differential equations with the Caputo derivative of two independent fractional orders.

Indirect interactions influence contact network structure and diffusion dynamics [PDF]

open access: yesRoyal Society Open Science, 2019
Interaction patterns at the individual level influence the behaviour of diffusion over contact networks. Most of the current diffusion models only consider direct interactions, capable of transferring infectious items among individuals, to build ...

One-dimensional Wiener process with the properties of partial reflection and delay

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2021
In this paper, we construct the two-parameter semigroup of operators associated with a certain one-dimensional inhomogeneous diffusion process and study its properties.

On a symmetrization of diffusion processes [PDF]

open access: yesQuantitative Finance, 2013
The latter author, together with collaborators, proposed a numerical scheme to calculate the price of barrier options. The scheme is based on a symmetrization of diffusion process. The present paper aims to give a mathematical credit to the use of the numerical scheme for Heston or SABR type stochastic volatility models.
