A Prehistorical Approach to Optimal Fluctuations for General Langevin Dynamics with Weak Gaussian White Noises

open access: yesApplied Sciences, 2022
The dynamics of a stochastic system that exhibits large fluctuations to a given state are almost deterministic due to weak random perturbations. Such large fluctuations occur with overwhelming probability in the vicinity of the so-called optimal path ...

$T$-law of large numbers for fuzzy numbers [PDF]

open access: yes, 1997
summary:The notions of a $t$-norm and of a fuzzy number are recalled. The law of large numbers for fuzzy numbers is defined. The fuzzy numbers, for which the law of large numbers holds, are investigated. The case when the law of large numbers is violated

Implicit Subgrid-Scale Modeling of a Mach 2.5 Spatially Developing Turbulent Boundary Layer

open access: yesEntropy, 2022
We employ numerically implicit subgrid-scale modeling provided by the well-known streamlined upwind/Petrov–Galerkin stabilization for the finite element discretization of advection–diffusion problems in a Large Eddy Simulation (LES) approach. Whereas its

Strong Laws of Large Numbers for 𝔹-Valued Random Fields

open access: yesDiscrete Dynamics in Nature and Society, 2009
We extend to random fields case, the results of Woyczynski, who proved Brunk's type strong law of large numbers (SLLNs) for 𝔹-valued random vectors under geometric assumptions.

Equivalence between Step Selection Functions and Biased Correlated Random Walks for Statistical Inference on Animal Movement. [PDF]

open access: yesPLoS ONE, 2015
Animal movement has a fundamental impact on population and community structure and dynamics. Biased correlated random walks (BCRW) and step selection functions (SSF) are commonly used to study movements.

Public Policy Through the Lens of Necessity

open access: yesVoices in Bioethics, 2021
Photo by Nick Fewings on Unsplash INTRODUCTION Necessity can drive people’s behavior to extremes, and at times, can provide an excuse for otherwise criminal, illegal actions that, under normal circumstances, would be morally wrong.

Means as Improper Integrals

open access: yesMathematics, 2019
The aim of this work is to study generalizations of the notion of the mean. Kolmogorov proposed a generalization based on an improper integral with a decay rate for the tail probabilities.

A Note on the Strong Law of Large Numbers for Arrays of Rowwise ρ˜-Mixing Random Variables

open access: yesDiscrete Dynamics in Nature and Society, 2011
Let {Xni,i≥1,n≥1} be an array of rowwise ρ˜-mixing random variables. Some strong law of large numbers for arrays of rowwise ρ˜-mixing random variables is studied under some simple and weak conditions.

Strong and Weak Convergence for Asymptotically Almost Negatively Associated Random Variables

open access: yesDiscrete Dynamics in Nature and Society, 2013
The strong law of large numbers for sequences of asymptotically almost negatively associated (AANA, in short) random variables is obtained, which generalizes and improves the corresponding one of Bai and Cheng (2000) for independent and identically ...
