Is thermal conductivity time‐dependent? [PDF]
physica status solidi (b), 2008 AbstractThe question whether thermal conductivity may be time dependent on short time scales is investigated and answered in the affirmative. For this purpose, we make use of a classical relation between the Brownian mean displacement and the thermal conductivity.

Time-periodic thermal rectification in heterojunction thermal diodes
International Journal of Heat and Mass Transfer, 2022 Abstract Thermal diodes that rectify time-periodic temperature ( T ) fields have been proposed for applications in waste heat scavenging and thermal control. Although these applications involve transient temperatures, prior analytical solutions for heat conduction in thermal diodes have focused on the steady-state response.

Travel-time-based thermal tracer tomography [PDF]
Hydrology and Earth System Sciences, 2016 Abstract. Active thermal tracer testing is a technique to get information about the flow and transport properties of an aquifer. In this paper we propose an innovative methodology using active thermal tracers in a tomographic setup to reconstruct cross-well hydraulic conductivity profiles.

Physical Time and Thermal Clocks [PDF]
Foundations of Physics, 2016 In this paper I discuss the concept of time in physics. I consider the thermal time hypothesis and I claim that thermal clocks and atomic clocks measure different physical times, whereby thermal time and relativistic time are not compatible with each other.

Determination of cardinal temperatures and thermal time requirement during germination and emergence of chickpea genotypes (Cicer arietinum L.) [PDF]
پژوهشهای حبوبات ایران, 2012 Determination of cardinal temperatures during seed germination and emergence as well as the thermal time requirement for each stage is essential in crop management and modeling of plant growth and development.

Thermal contact: mischief and time scales [PDF]
Journal of Physics A: Mathematical and Theoretical, 2019 We discuss what kind of quantum channels can enable thermalization processes. We show that in order to determine a system's temperature, a thermometer needs to dynamically gain information about the system's local Hamiltonian and not just its state. We illustrate this showing that any temperature measurement protocol that does not resolve the system's ...
