$$a_{1}$$ a 1 meson-nucleon coupling constant at finite temperature from the soft-wall AdS/QCD model

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We study the temperature dependence of the $$a_1$$ a 1 meson-nucleon coupling constant in the framework of the soft-wall AdS/QCD model with thermal dilaton field.

Sliding mode analysis applied to improve the dynamical response of a spherical 3D wind sensor for Mars atmosphere [PDF]

open access: yes, 2017
The objective of this paper is to show how the structure of a thermal wind anemometer can be tuned to ensure a fast response when the sensor works in closed loop configuration (constant temperature operation).

Constant rate thermal analysis for thermal stability studies of polymers [PDF]

open access: yes, 2011
This paper explores the relationship between the shapes of temperature-time curves obtained from experimental data recorded by means of constant rate thermal analysis (CRTA) and the kinetic model followed by the thermal degradation reaction.

Approximate model for evaluation of thermal-hydraulic transients associated with rapid power increase in research nuclear reactor [PDF]

open access: yesNuclear Technology and Radiation Protection, 2020
A simple model, for the estimation of changes in the nuclear fuel element cladding temperature as well as the conditions of the formation of the onset of nucleate boiling, is proposed.

Cosmic ray moderation of the thermal instability [PDF]

open access: yes, 2004
We apply the Hermite-Bieler theorem in the analysis of the effect of cosmic rays on the thermal stability of an initially uniform, static background. The cosmic rays were treated in a fluid approximation and the diffusion coefficient was assumed to be ...

Application of Particle Swarm Optimization (PSO) Algorithm in Determining Thermodynamics of Solid Combustibles

open access: yesEnergies, 2023
The thermodynamics of a solid are crucial in predicting thermal responses and fire behaviors, and they are commonly determined by inverse modeling and optimization algorithms at constant heat flux.

Demographic characteristics of Bryobia rubrioculus (Acari: Tetranychidae) reared on sour cherry leaves at different constant temperatures

open access: yesPersian Journal of Acarology, 2015
The life history of Bryobia rubrioculus Scheuten (Acari: Tetranychidae) on sour cherry leaves was studied based on the age-stage, two-sex life table at nine constant temperatures (15, 17.5, 20, 22.5, 25, 27.5, 30, 32.5 and 33.5 ºC), 60 ± 5% RH and a ...
