The geodesic dispersion phenomenon in random field dynamics: probing the shape of time

open access: yesJournal of Physics: Complexity
Gaussian random fields (GRFs) provide a fundamental framework for modeling stochastic spatial phenomena with broad applications in physics and related fields.

Influence of Corrosion Degradation on the Dynamic Response of Steel Plates

open access: yesPolish Maritime Research
Corrosion, particularly in marine and offshore environments, often leads to material loss and surface irregularities that compromise structural integrity. Traditional non-destructive testing methods, such as ultrasonic thickness measurements, are limited

Polar Functions for Anisotropic Gaussian Random Fields

open access: yesAbstract and Applied Analysis, 2014
Let X be an (N, d)-anisotropic Gaussian random field. Under some general conditions on X, we establish a relationship between a class of continuous functions satisfying the Lipschitz condition and a class of polar functions of X. We prove upper and lower

Itô equation model for dispersion of solutes in heterogeneous media

open access: yesJournal of Numerical Analysis and Approximation Theory, 2008
Transport processes in heterogeneous media such as ionized plasmas, natural porous media, and turbulent atmosphere are often modeled as diffusion processes in random velocity fields. Using the Itô formalism, we decompose the second spatial moments of the

Non-Parametric Estimation of the Renewal Function for Multidimensional Random Fields

open access: yesMathematics
This paper addresses the almost sure convergence and the asymptotic normality of an estimator of the multidimensional renewal function based on random fields. The estimator is based on a sequence of non-negative independent and identically distributed (i.
