Entropy Generation through Deterministic Spiral Structures in a Corner Boundary-Layer Flow

open access: yesEntropy, 2015
It is shown that nonlinear interactions between boundary layers on adjacent corner surfaces produce deterministic stream wise spiral structures. The synchronization properties of nonlinear spectral velocity equations of Lorenz form yield clearly defined ...

Entropy-based analysis and bioinformatics-inspired integration of global economic information transfer. [PDF]

open access: yesPLoS ONE, 2013
The assessment of information transfer in the global economic network helps to understand the current environment and the outlook of an economy. Most approaches on global networks extract information transfer based mainly on a single variable. This paper

Sublimation Study of Six 5-Substituted-1,10-Phenanthrolines by Knudsen Effusion Mass Loss and Solution Calorimetry

open access: yesEntropy, 2022
The vapor pressures of six solid 5-X-1,10-phenanthrolines (where X = Cl, CH3, CN, OCH3, NH2, NO2) were determined in suitable temperature ranges by Knudsen Effusion Mass Loss (KEML).

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.

Entropy Generation through Deterministic Spiral Structures in Corner Flows with Sidewall Surface Mass Injection

open access: yesEntropy, 2016

A New Odd Beta Prime-Burr X Distribution with Applications to Petroleum Rock Sample Data and COVID-19 Mortality Rate

open access: yesData, 2023
In this article, we pioneer a new Burr X distribution using the odd beta prime generalized (OBP-G) family of distributions called the OBP-Burr X (OBPBX) distribution.

Large deviations for empirical entropies ofg-measures [PDF]

open access: yesNonlinearity, 2005
Summary: The entropy of an ergodic finite-alphabet process can be computed from a single typical sample path \(x^n_1\) using the entropy of the \(k\)-block empirical probability and letting k grow with \(n\) roughly like \(\log n\). We further assume that the distribution of the process is a g-measure.

Transitional Intermittency Exponents Through Deterministic Boundary-Layer Structures and Empirical Entropic Indices

open access: yesEntropy, 2014
A computational procedure is developed to determine initial instabilities within a three-dimensional laminar boundary layer and to follow these instabilities in the streamwise direction through to the resulting intermittency exponents within a fully ...

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.

Entropy conditions for L r -convergence of empirical processes [PDF]

open access: yesAdvances in Computational Mathematics, 2008
Let \(P_n\) be the empirical measure for a sample of \(n\) independent random elements with joint distribution \(P\). Furthermore, let \({\mathcal F}\) be a class of real-valued (bounded) functions defined on the sample space. Then it is known that \(\sup_{f\in {\mathcal F}}|P_nf - Pf| \to 0\) almost surely provided that \({\mathcal F}\) admits a ...
