Gravitation and Thermodynamics [PDF]

open access: bronzeNature, 1917
DR. TODD (NATURE, March 1) suggests that when one gravitative mass approaches another it acquires heat. This might occur when, as is usually (but not always) the case, the body moves up the gradient of potential; for then the energy of field displaced by the body would increase.

Thermoelasticity and Irreversible Thermodynamics

open access: green, 1956
A unified treatment is presented of thermoelasticity by application and further developments of the methods of irreversible thermodynamics. The concept of generalized free energy introduced in a previous publication plays the role of a ``thermoelastic ...

Hamiltonian Thermodynamics [PDF]

open access: yesNelineinaya Dinamika, 2020
It is believed that thermodynamic laws are associated with random processes occurring in the system and, therefore, deterministic mechanical systems cannot be described within the framework of the thermodynamic approach. In this paper, we show that thermodynamics (or, more precisely, a thermodynamically-like description) can be constructed even for ...

Conduction and Inertia Correction for Transient Thermocouple Measurements. Part I: Analytical and Numerical Modelling [PDF]

open access: yesE3S Web of Conferences, 2022
Two-wire thermocouples are often used for temperature measurements. Under transient conditions, measurement errors can occur due to capacitive inertia and heat conduction along the stem of the thermocouples.

Conduction and Inertia Correction for Transient Thermocouple Measurements. Part II: Experimental Validation and Application [PDF]

open access: yesE3S Web of Conferences, 2022
Thermocouples are often used for temperature measurements. Under transient conditions, measurement errors can occur due to capacitive inertia and heat conduction along the stem of the thermocouples. To correct such errors, a method is presented in Part I

Validated numerical simulation of airflow in child respiratory airways [PDF]

open access: yesEPJ Web of Conferences, 2022
Both pulmonary airway geometry and breathing pattern evolve from birth to adulthood. These gradual changes significantly influence airflow dynamics and subsequently particle transport and deposition.
