Differential Models, Numerical Simulations and Applications

open access: yesAxioms, 2021
Differential models, numerical methods and computer simulations play a fundamental role in applied sciences. Since most of the differential models inspired by real world applications have no analytical solutions, the development of numerical methods and ...

Semiconvection: numerical simulations [PDF]

open access: yes, 2013
A grid of numerical simulations of double-diffusive convection is presented for the astrophysical case where viscosity (Prandtl number Pr) and solute diffusivity (Lewis number Le) are much smaller than the thermal diffusivity.

Numerical Simulations of Spin Glass Systems [PDF]

open access: yes, 1997
We discuss the status of Monte Carlo simulations of (mainly finite dimensional) spin glass systems. After a short historical note and a brief theoretical introduction we start by discussing the (crucial) 3D case: the warm phase, the critical point and ...

Analysis of the inadequacy of determining the spectral characteristics of optical fibre periodic structures by way of numerical modelling

open access: yesMetrology and Measurement Systems, 2020
As part of the work, the error level of simulations of uniform optical-fibre Bragg gratings was determined using the transitionmatrixmethod. The errorswere established by comparing the transmission characteristics of the structures obtained by simulation

An approach to consider the arterial residual stresses in modelling of a patient-specific artery

open access: yesAdvances in Mechanical Engineering, 2016
In this work, the residual stress state of a human common carotid artery is predicted using the so-called thermomechanical analogy approach. The purpose of the approach is to enable consistent mapping of residual stresses and the respective configuration

A random-forest-derived 35-year snow phenology record reveals climate trends in the Yukon River Basin [PDF]

open access: yesThe Cryosphere
This study presents a 35-year snow phenology record for the Yukon River Basin (YRB), developed using a random forest (RF) model at a 3.125 km resolution, capturing detailed trends in snowmelt onset and snow-off.

Numerical simulations of dwarf galaxy merger trees [PDF]

open access: yes, 2014
We investigate the evolution of dwarf galaxies using N -body/SPH simulations that incorporate their formation histories through merger trees constructed using the ex- tended Press-Schechter formalism.

Numerical Simulations of Radiatively-Driven Dusty Winds [PDF]

open access: yes, 2013
[abridged] Radiation pressure on dust grains may be an important mechanism in driving winds in a wide variety of astrophysical systems. However, the efficiency of the coupling between the radiation field and the dusty gas is poorly understood in ...

Direct numerical simulations of capillary wave turbulence [PDF]

open access: yes, 2014
This work presents Direct Numerical Simulations of capillary wave turbulence solving the full 3D Navier Stokes equations of a two-phase flow. When the interface is locally forced at large scales, a statistical stationary state appears after few forcing ...

Scaling in Numerical Simulations of Domain Walls [PDF]

open access: yes, 2002
We study the evolution of domain wall networks appearing after phase transitions in the early Universe. They exhibit interesting dynamical scaling behaviour which is not yet well understood, and are also simple models for the more phenomenologically ...
