Entropy in the Tangled Nature Model of Evolution

open access: yesEntropy, 2017
Applications of entropy principles to evolution and ecology are of tantamount importance given the central role spatiotemporal structuring plays in both evolution and ecological succession.

Automated Emotion Identification Using Fourier–Bessel Domain-Based Entropies

open access: yesEntropy, 2022
Human dependence on computers is increasing day by day; thus, human interaction with computers must be more dynamic and contextual rather than static or generalized.

Application of Entropy Measures on Intrinsic Mode Functions for the Automated Identification of Focal Electroencephalogram Signals

open access: yesEntropy, 2015
The brain is a complex structure made up of interconnected neurons, and its electrical activities can be evaluated using electroencephalogram (EEG) signals. The characteristics of the brain area affected by partial epilepsy can be studied using focal and

Research of Planetary Gear Fault Diagnosis Based on Permutation Entropy of CEEMDAN and ANFIS

open access: yesSensors, 2018
For planetary gear has the characteristics of small volume, light weight and large transmission ratio, it is widely used in high speed and high power mechanical system. Poor working conditions result in frequent failures of planetary gear.

An empirical assessment of the entropy maximising family of interaction models [PDF]

open access: yesIrish Geography, 1983
The parameters, and consequently the performance level, of statistical models of spatial interaction are particularly dependent on the spatial organisation framework which is used to organise interaction data and the way in which the costs of interaction arc measured.

Using Graph and Vertex Entropy to Compare Empirical Graphs with Theoretical Graph Models

open access: yesEntropy, 2016
Over the years, several theoretical graph generation models have been proposed. Among the most prominent are: the Erdős–Renyi random graph model, Watts–Strogatz small world model, Albert–Barabási preferential attachment model, Price citation model, and ...

Thermodynamics and time-average [PDF]

open access: yes, 2004
For a dynamical system far from equilibrium, one has to deal with empirical probabilities defined through time-averages, and the main problem is then how to formulate an appropriate statistical thermodynamics.

Empirical Maximum Entropy Methods [PDF]

open access: yesAIP Conference Proceedings, 2006
A method, which we suggest to call the Empirical Maximum Entropy method, is implicitly present at Maximum Entropy Empirical Likelihood method, as its special, non‐parametric case. From this vantage point the entropy‐based empirical approach to estimation is surveyed.

Criticality in Pareto Optimal Grammars?

open access: yesEntropy, 2020
What are relevant levels of description when investigating human language? How are these levels connected to each other? Does one description yield smoothly into the next one such that different models lie naturally along a hierarchy containing each ...
