Entropy production in an energy balance Daisyworld model

open access: yes, 2008
Daisyworld is a simple mathematical model of a planetary system that exhibits self-regulation due to the nature of feedback between life and its environment.

The minimum local cross-entropy criterion for inferring risk-neutral price distributions from traded options prices [PDF]

open access: yes, 2004
A quantity known as the Local Cross-Entropy (LCE) for a density is proposed, defined to be the local derivative of the Cross-Entropy between a density and a ’kernel-smoothed’ version of itself, with respect to bandwidth of the smoothing.

A radiative–convective model computing precipitation with the maximum entropy production hypothesis [PDF]

open access: yesGeoscientific Model Development
All climate models use parameterizations and tuning in order to be accurate. The different parameterizations and tuning processes are the primary source of difference between models.

Analysis of Energy Loss Characteristics of Vertical Axial Flow Pump Based on Entropy Production Method under Partial Conditions

open access: yesEntropy, 2022
The energy loss of the vertical axial flow pump device increases due to the unstable internal flow, which reduces the efficiency of the pump device and increases its energy consumption of the pump device.

Thermodynamic Analysis of Bistability in Rayleigh–Bénard Convection

open access: yesEntropy, 2020
Bistability is often encountered in association with dissipative systems far from equilibrium, such as biological, physical, and chemical phenomena.

Maximum Entropy Production and Maximum Shannon Entropy as Germane Principles for the Evolution of Enzyme Kinetics

open access: yes, 2013
There have been many attempts to use optimization approaches to study the biological evolution of enzyme kinetics. Our basic assumption here is that the biological evolution of catalytic cycle fluxes between enzyme internal functional states is accompanied by increased entropy production of the fluxes and increased Shannon information entropy of the ...

Maximum Entropy Production for Optimizing Carbon Catalysis: An Active-Matter-Inspired Approach

open access: yesPhysical Sciences Forum
The static topology of surface characteristics and active sites in catalysis overlooks a crucial element: the dynamic processes of optimal pattern formation over time and the creation of intermediate structures that enhance reactions.

Spectral Entropy in a Boundary-Layer Flow

open access: yesEntropy, 2011
This article presents a comparison of the entropy production in a laminar and transitional boundary layer flow with the spectral entropy produced in a region of instability induced by an imposed periodic disturbance.

Transport of charged particles: Entropy production and Maximum Dissipation Principle [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 2015
In order to describe the dynamics of crowded ions (charged particles), we use an energetic variation approach to derive a modified Poisson-Nernst-Planck (PNP) system which includes an extra dissipation due to the effective velocity differences between ion species.
