Entropy Generation and Heat Transfer Performances of Al2O3-Water Nanofluid Transitional Flow in Rectangular Channels with Dimples and Protrusions

open access: yesEntropy, 2016
Nanofluid has great potentials in heat transfer enhancement and entropy generation decrease as an effective cooling medium. Effects of Al2O3-water nanofluid flow on entropy generation and heat transfer performance in a rectangular conventional channel ...

On Thermodynamic Interpretation of Transfer Entropy

open access: yesEntropy, 2013
We propose a thermodynamic interpretation of transfer entropy near equilibrium, using a specialised Boltzmann’s principle. The approach relates conditional probabilities to the probabilities of the corresponding state transitions.

Shortcomings of Transfer Entropy and Partial Transfer Entropy: Extending Them to Escape the Curse of Dimensionality [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2020
Transfer entropy (TE) captures the directed relationships between two variables. Partial transfer entropy (PTE) accounts for the presence of all confounding variables of a multivariate system and infers only about direct causality. However, the computation of partial transfer entropy involves high dimensional distributions and thus may not be robust in

Specific transfer entropy and other state-dependent transfer entropies for continuous-state input-output systems [PDF]

open access: yesPhysical Review E, 2017
Since its original formulation in 2000, transfer entropy has become an invaluable tool in the toolbox of nonlinear dynamicists working with empirical data. Transfer entropy and its generalizations provide a precise definition of uncertainty and information transfer that are central to the coupled systems studied in nonlinear science.

Fault Root Cause Tracking of the Mechanical Components of CNC Lathes Based on Information Transmission

open access: yesSensors, 2023
This study proposes a new method for the immediate fault warning and fault root tracing of CNC lathes. Here, the information acquisition scheme was formulated based on the analysis of the coupling relationship between the mechanical parts of CNC lathes ...

Informative and misinformative interactions in a school of fish [PDF]

open access: yes, 2017
It is generally accepted that, when moving in groups, animals process information to coordinate their motion. Recent studies have begun to apply rigorous methods based on Information Theory to quantify such distributed computation.

t-Entropy formulae for concrete classes of transfer operators

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
t-Entropy is a principal object of the spectral theory of operators, generated by dynamical systems, namely, weighted shift operators and transfer operators.

A controlled transfer entropy approach to detect asymmetric interactions in heterogeneous systems

open access: yesJournal of Physics: Complexity, 2023
Transfer entropy is emerging as the statistical approach of choice to support the inference of causal interactions in complex systems from time-series of their individual units.

Performance analysis of micro-fin tubes compared to smooth tubes as a heat transfer enhancement technique for flow condensation

open access: yesEnergy Nexus, 2022
Heat transfer enhancement techniques are accompanied by pressure drop amplification, detrimentally affecting their performance; entropy generation analysis is an effective approach to assess heat transfer enhancement along with resulting pressure drop ...
