On the Holographic Bound in Newtonian Cosmology

Entropy, 2018
The holographic principle sets an upper bound on the total (Boltzmann) entropy content of the Universe at around 10 123 k B ( k B being Boltzmann’s constant).

Wave focusing by submerged islands and gravitational analogues

Physical Review Research, 2022
We study water waves propagating over a smooth obstacle in a fluid of varying depth, motivated by the observation that submerged islands in the ocean act as effective lenses that increase the amplitude and destructive power of tsunami waves near focal ...

Fluid flow approximation of PEPA models [PDF]

Second International Conference on the Quantitative Evaluation of Systems (QEST'05), 2005
In this paper we present a novel performance analysis technique for large scale systems modelled in the stochastic process algebra PEPA. In contrast to the well-known approach of analysing via continuous time Markov chains, our underlying mathematical representation is a set of coupled ordinary differential equations (ODEs).

Blade coating analysis of a Williamson fluid

Results in Physics, 2017
In this article, a mathematical model of a blade coating analysis of the thin film of a Williamson fluid is developed when it passes through the small gap between a blade and a moving substrate.

Bottom Multi-Parameter Bayesian Inversion Based on an Acoustic Backscattering Model

Journal of Marine Science and Engineering
The geoacoustic and physical properties of the bottom, as well as spatial distribution, are crucial factors in analyzing the underwater acoustic field structure and establishing a geoacoustic model.

Numerical approximation of fluid-structure interaction problems [PDF]

Applied and Computational Mechanics, 2008
This paper is devoted to numerical approximations of fluid-structure interaction problems. Namely the problem of interaction of turbulent flow over flexibly supported airfoil is addressed. In order to model the turbulence effects the flow is described by

Entropy approximations for simple fluids

Physical Review E
Liquid state entropy formulas based on configurational probability distributions are examined for Lennard-Jones fluids across a range temperatures and densities. These formulas are based on expansions of the entropy in series of $n$-body distribution functions. We focus on two special cases.

High-order fluid solver based on a combined compact integrated RBF approximation and its fluid structure interaction applications

, 2016
In this study, we present a high-order numerical method based on a combined compact integrated RBF (IRBF) approximation for viscous flow and fluid structure interaction (FSI) problems.
