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

Limits of relative entropies associated with weakly interacting particle systems [PDF]
, 2015 The limits of scaled relative entropies between probability distributions associated with N-particle weakly interacting Markov processes are considered. The convergence of such scaled relative entropies is established in various settings. The analysis is

Conditional entropy of ordinal patterns [PDF]
, 2014 In this paper we investigate a quantity called conditional entropy of ordinal patterns, akin to the permutation entropy. The conditional entropy of ordinal patterns describes the average diversity of the ordinal patterns succeeding a given ordinal ...

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

Entropy of Financial Time Series Due to the Shock of War
Entropy, 2023 The concept of entropy is not uniquely relevant to the statistical mechanics but, among others, it can play pivotal role in the analysis of a time series, particularly the stock market data.

EMPIRICAL COPULAS FOR CDO TRANCHE PRICING USING RELATIVE ENTROPY [PDF]
International Journal of Theoretical and Applied Finance, 2007 We discuss the general optimization problem of choosing a copula with minimum entropy relative to a specified copula and a computationally intensive procedure to solve its dual. These techniques are applied to constructing an empirical copula for CDO tranche pricing.

Criticality in Pareto Optimal Grammars?
Entropy, 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 ...

Bootstrap methods for the empirical study of decision-making and information flows in social systems [PDF]
, 2013 : We characterize the statistical bootstrap for the estimation of information theoretic quantities from data, with particular reference to its use in the study of large-scale social phenomena.

A prediction model of aquaculture water quality based on multiscale decomposition
Mathematical Biosciences and Engineering, 2021 In the field of intensive aquaculture, the deterioration of water quality is one of the main factors restricting the normal growth of aquatic products. Predicting water quality in real time constitutes the theoretical basis for the evaluation, planning ...

Empirical Considerations of Entropy. II. The Entropies of Inorganic Complex Ions [PDF]
The Journal of Chemical Physics, 1953 A method is proposed by which the partial molal entropies of aqueous complex ions can be correlated in a simple manner as a function of the ratio of their charge to interatomic distance. The agreement obtained between the observed values and those calculated by this method has been shown to be within the accuracy of the experimental data.
