Quasi-equilibrium nonadditivity [PDF]

open access: yes, 2014
The possibility that a short-range interacting system exhibits nonadditivity is investigated. After the discussion on the precise definition of additivity and its consequence, we show that it is possible when the system is in a quasi-equilibrium state by

TCAD Modeling of Resistive-Switching of HfO2 Memristors: Efficient Device-Circuit Co-Design for Neuromorphic Systems

open access: yesFrontiers in Nanotechnology, 2021
In neuromorphic computing, memristors (or “memory resistors”) have been primarily studied as key elements in artificial synapse implementations, where the memristor provides a variable weight with intrinsic long-term memory capabilities, based on its ...

Cluster Statistical Thermodynamics (CST) — To Efficiently Calculate Quasi-Static Deformation at Finite Temperature Based on Molecular Potential [PDF]

open access: yes, 2007
For quasi-static deformations in engineering practice, molecular dynamics (MD) simulation requires computation resources that are not affordable even with ever-increasing computing power. In order to overcome this weakness, we developed a new method called cluster statistical thermodynamics (CST).

Galaxy clustering and thermodynamics - Quasi-static evolution of b(t)

open access: yesThe Astrophysical Journal, 1986
A simple evolution equation is derived for b(t), the ratio of gravitational correlation energy to kinetic energy in the expanding universe, which gives the observed asymptotic value of 0.7 and also predicts the behavior of the ratio at earlier times. The equation is obtained by combining the cosmic energy equation with the BBGKY clustering hierarchy ...

Green's function theory of quasi-two-dimensional spin-half Heisenberg ferromagnets: stacked square versus stacked kagom\'e lattice

open access: yes, 2006
We consider the thermodynamic properties of the quasi-two-dimensional spin-half Heisenberg ferromagnet on the stacked square and the stacked kagom\'e lattices by using the spin-rotation-invariant Green's function method.

Mechanical Proof of the Second Law of Thermodynamics Based on Volume Entropy [PDF]

open access: yes, 2007
In a previous work (M. Campisi. Stud. Hist. Phil. M. P. 36 (2005) 275-290) we have addressed the mechanical foundations of equilibrium thermodynamics on the basis of the Generalized Helmholtz Theorem.

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

open access: yesAdvanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

An analytic effective model for hairy black holes

open access: yesPhysics Letters B, 2018
Hairy black holes (BHs) have macroscopic degrees of freedom which are not associated with a Gauss law. As such, these degrees of freedom are not manifest as quasi-local quantities computed at the horizon.

Diagnosing Cracks in the Injector Nozzles of Marine Internal Combustion Engines during Operation Using Vibration Symptoms

open access: yesApplied Sciences, 2023
In the operation of internal combustion engines, despite technical state monitoring, some cracks that develop in metal components go undetected, leading to secondary, critical, or degradation damage. The diagnostic systems used in floating objects mainly

Relation between positional specific heat and static relaxation length: Application to supercooled liquids [PDF]

open access: yes, 2005
A general identification of the {\em positional specific heat} as the thermodynamic response function associated with the {\em static relaxation length} is proposed, and a phenomenological description for the thermal dependence of the static relaxation ...
