Temperature Relaxation in Hot Dense Hydrogen [PDF]

open access: yesPhysical Review Letters, 2008
Temperature equilibration of hydrogen is studied for conditions relevant to inertial confinement fusion. New molecular-dynamics simulations and results from quantum many-body theory are compared with Landau-Spitzer (LS) predictions for temperatures T from 50 eV to 5000 eV, and densities with Wigner-Seitz radii r_s = 1.0 and 0.5.

Measuring the temperature of hot nuclear fragments [PDF]

open access: yesNuclear Physics A, 2010
A new thermometer based on fragment momentum fluctuations is presented. This thermometer exhibited residual contamination from the collective motion of the fragments along the beam axis. For this reason, the transverse direction has been explored. Additionally, a mass dependence was observed for this thermometer.

Automatic Control of Hot Metal Temperature

open access: yesMetals, 2022
To achieve the automation of blast furnace operation, an automatic control system for hot metal temperature (HMT) was developed. Nonlinear model predictive control (NMPC) which predicts up to ten-hour-ahead HMT and calculates appropriate control actions of pulverized coal rate (PCR) was constructed.

Body Temperature Regulation in Hot Environments [PDF]

open access: yesPLOS ONE, 2016
Organisms in hot environments will not be able to passively dissipate metabolically generated heat. Instead, they have to revert to evaporative cooling, a process that is energetically expensive and promotes excessive water loss. To alleviate these costs, birds in captivity let their body temperature increase, thereby entering a state of hyperthermia ...

Effective temperatures of hot Brownian motion [PDF]

open access: yesPhysical Review E, 2014
We derive generalized Langevin equations for the translational and rotational motion of a heated Brownian particle from the fluctuating hydrodynamics of its non-isothermal solvent. The temperature gradient around the particle couples to the hydrodynamic modes excited by the particle itself so that the resulting noise spectrum is governed by a frequency-

The effective temperatures of hot stars [PDF]

open access: yesSymposium - International Astronomical Union, 1997
We review the effective temperature scale of hot (≤ 10 kK) stars, including results from direct, continuum and ionization equilibrium techniques. We discuss the impact of recent developments in theoretical model atmospheres for OB subdwarfs, dwarfs and supergiants, white dwarfs and Wolf Rayet stars and present a revised Teff scale for OB stars.

Skin Temperature in Hot Environment

open access: yesNippon Eiseigaku Zasshi (Japanese Journal of Hygiene), 1971
It has been suggested that the immersion of subjects into a hot water bath (Bath Method) may be useful and simple method for testing human heat tolerance. It is probable that the bath method may fail to evaluate valid heat tolerance because of the forced uniformization of skin temperature.

Hot O and nighttime ionospheric temperatures [PDF]

open access: yesGeophysical Research Letters, 2000
By analysing a large set of St. Santin F region Incoherent Scatter (IS) data for low solar activity we find nighttime ion temperature (Ti) on average to be apparently slightly higher than electron temperature (Te). We show that this difference is a bias incurred by the IS spectral analysis procedure owing to the neglect of H+ ions in the 300–500 km ...

Equivalent temperature of hot electrons

open access: yesSolid-State Electronics, 1980
Abstract The two extensions of the Einstein relation qDpar = kTeμpar and qDpar = kT′eμ′and define, in the case of hot electrons, two different electron temperatures Te and T′e. It is shown here that the two interpretations are fully equivalent in that they lead to the noise expressions S I (0)=4kT( I V and S I (0) = 4kT′ e (

Infinite Temperature's Not So Hot

open access: yes, 2022
It has been argued that the entanglement spectrum of a static patch of de Sitter space must be flat, or what is equivalent, the temperature parameter in the Boltzmann distribution must be infinite. This seems absurd: quantum fields in de Sitter space have thermal behavior with a finite temperature proportional to the inverse radius of the horizon.
