NUMERICAL SIMULATIONS OF QUIET SUN MAGNETISM: ON THE CONTRIBUTION FROM A SMALL-SCALE DYNAMO [PDF]

open access: yes, 2014
We present a series of radiative MHD simulations addressing the origin and distribution of the mixed polarity magnetic field in the solar photosphere. To this end, we consider numerical simulations that cover the uppermost 2–6 Mm of the solar convection ...

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors

open access: yesPopulation Ecology, EarlyView.
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

The Impact of a New Container Port on the Greenhouse Gas Pollution

open access: yesBusiness Systems Research
Large vessels that call at European ports will have to pay for their CO2 emissions from transporting cargo that enters or goes from a European port since January 2024. The costs will increase with increasing global trade.

Numerical models performance to predict drying liquid water in porous building materials: Comparison of experimental and simulated drying water content profiles

open access: yesCogent Engineering, 2017
A practical way to evaluate drying in porous building materials is through environmental conditioning drying curve where drying is influenced by external factors such as environmental conditions and by the material properties.

Numerical simulations of rotating sunspots [PDF]

open access: yes, 2006
A numerical model of idealized, axisymmetric, rotating sunspots is presented. The model contains a compressible plasma described by the nonlinear MHD equations, with density and temperature gradients simulating the upper layer of the sun’s convection ...

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 ...

An Adaptive Management Model for Brown Bears in Hokkaido: Based on Total Population and the Number of Nuisance Bears

open access: yesPopulation Ecology, EarlyView.
Bear management changes management actions according to the horizontal axis of the population size and the vertical axis of the number of nuisance bears. Aiming for the target population size of Ntar, Actions I and II protect the bears, and Action IV reduces the population.

An impact study of a capsule with a rigid wall using the SPH approach [PDF]

open access: yesINCAS Bulletin, 2015
Impact problems have always been of interest in the Aerospace industry because events such as “bird-strikes” occur quite often and necessary studies must be performed to observe the behavior of structures during the impact.

Reliability-Oriented Design of a Solar-PV Deployments

open access: yesEnergies, 2021
Increasing restrictions on the emission of greenhouse gases by the standards and the European Union’s policy aims at increasing the share of renewable energy sources in the energy mix of the Member States. Subsequently, we observe a rapid increase in the

Numerical simulations of time resolved quantum electronics

open access: yes, 2014
This paper discusses the technical aspects - mathematical and numerical - associated with the numerical simulations of a mesoscopic system in the time domain (i.e. beyond the single frequency AC limit).
