Entropy of Mixing and the Glass Transition of Amorphous Mixtures

open access: yesEntropy, 2008
Different equations have been proposed for estimating the glass transition temperature of amorphous mixtures. All such expressions lack a term to account for the effect of the entropy of mixing on the glass transition.

Mixing, entropy and reactive solute transport

open access: yesGeophysical Research Letters, 2012
Mixing processes significantly affect reactive solute transport in fluids. For example, contaminant degradation in environmental aquatic systems can be limited either by the availability of one or more reactants, brought into contact by physical mixing ...

Entropy Generation Rates in Two-Dimensional Rayleigh–Taylor Turbulence Mixing

open access: yesEntropy, 2018
Entropy generation rates in two-dimensional Rayleigh–Taylor (RT) turbulence mixing are investigated by numerical calculation. We mainly focus on the behavior of thermal entropy generation and viscous entropy generation of global quantities with ...

On Transmitted Complexity Based on Modified Compound States

open access: yesEntropy, 2023
Based on the classical dynamical entropy, the channel coding theorem is investigated. Attempts to extend the dynamical entropy to quantum systems have been made by several researchers In 1999, Kossakowski, Ohya and I introduced the quantum dynamical ...

Analysis of losses in the mixing section of the central air conditioner using the entropy-statistical method [PDF]

open access: yesMATEC Web of Conferences, 2020
The article presents an entropy-statistical analysis of losses in the mixing section of a central air conditioner. The temperature and humidity of the outdoor and recirculating air were measured.

Geometric Entropies of Mixing (EOM) [PDF]

open access: yesOpen Systems & Information Dynamics, 2006
Trigonometric and trigonometric-algebraic entropies are introduced and are given an axiomatic characterization. Regularity increases the entropy and the maximal entropy is shown to result when a regular n-gon is inscribed in a circle. A regular n-gon circumscribing a circle gives the largest entropy reduction, or the smallest change in entropy from ...

Symbolic dynamics on amenable groups: the entropy of generic shifts [PDF]

open access: yes, 2015
Let $G$ be a finitely generated amenable group. We study the space of shifts on $G$ over a given finite alphabet $A$. We show that the zero entropy shifts are generic in this space, and that more generally the shifts of entropy $c$ are generic in the ...

The lattice distortion, mechanical and thermodynamic properties of A(Zr0.2Sn0.2Ti0.2Hf0.2Nb0.2)O3 (A = Sr, Ba) high-entropy perovskite with B-site disorder: First principles prediction

open access: yesMaterials & Design, 2022
High-entropy perovskite oxides are novel high-entropy ceramics developing recently. In this work, the local lattice distortion, mechanical and thermodynamic properties of perovskites A(Zr0.2Sn0.2Ti0.2Hf0.2Nb0.2)O3 (A = Sr, Ba) are explored using the ...
