THE STEFAN PROBLEM WITH KINETIC FUNCTIONS AT THE FREE BOUNDARY [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 1999
This paper considers a class of one-dimensional solidification problem in which kinetic undercooling is incorporated into the temperature condition at the interface. A model problem with nonlinear kinetic law is considered.

From dusk till dawn: ecoacoustic monitoring reveals wind energy impacts on roding Eurasian woodcock Scolopax rusticola

open access: yesWildlife Biology, EarlyView.
Renewable energy is vital for reducing carbon emissions and yet its infrastructure poses challenges to biodiversity. While the impacts of wind power on bats and raptors are well‐studied, the effects on elusive species remain largely unknown. The Eurasian woodcock Scolopax rusticola, a nocturnal forest bird, performs characteristic courtship flights at ...

Numerical Study of One-Dimensional Stefan Problem … THERMAL SCIENCE [PDF]

open access: yes, 2013
A finite difference approach to a one-dimensional Stefan problem with periodic boundary conditions is studied. The evolution of the moving boundary and the temperature field are simulated numerically, and the effects of the Stefan number and the ...

Abundance, trends, and challenges facing mountain goats throughout their North American distribution

open access: yesWildlife Society Bulletin, EarlyView.
Our survey of states and provinces revealed that 13% of native mountain goat populations increased during the past 10 years, whereas 38% declined. For introduced populations, increases were roughly equal to declines. Rates of change were positively associated with being introduced or pioneering, and negatively associated with heavy snow, and, to a ...

Mechanism of heating of massive bodies by beaming in theoretical counterflow

open access: yesЛитьë и металлургия, 2000
The article presents numerical solution of the problem heating of plate form blanks by beaming at Stefan-Boltsman’s law while heat interchange with the flow of heating gases in conditions of theoretical counter flow. The results of the numerical solution

Building Blocks as Experiences in Dynamic Capacitated Arc Routing Problems

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT The dynamic capacitated arc routing problem (DCARP) aims to update the service paths of vehicles in the capacitated arc routing problem when uncertain factors deteriorate the current schedule of vehicles' services. A DCARP scenario comprises a series of DCARP instances that share similarities with each other. Therefore, optimisation experience

Anisotropy in Dry‐Type Valve‐Side Bushings of Converter Transformer: Phenomena and Effects

open access: yesHigh Voltage, EarlyView.
ABSTRACT The safe and stable working of dry‐type valve‐side bushings, important components of converter transformers, is essential. In recent years, poor design has led to several core breakdown, flashover and cracking failures. The bushing cores, composed of crepe paper and aluminium foil, exhibit significant anisotropic physical properties due to its

An influence of the false bottom on the nonlinear dynamics of the water freezing process

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
The current paper casts the light on the processes of structural-phase transitions during the freezing salt water, including the false bottom effects. A nonlinear mathematical model of heat and mass transfer was obtained.
