Generalized Entropies, Variance and Applications [PDF]

open access: yesEntropy, 2020
The generalized cumulative residual entropy is a recently defined dispersion measure. In this paper, we obtain some further results for such a measure, in relation to the generalized cumulative residual entropy and the variance of random lifetimes. We show that it has an intimate connection with the non-homogeneous Poisson process.

Entropy generation of nanofluid flow in hexagonal microchannel

open access: yesJournal of Taibah University for Science, 2022
A new model for entropy generation number in hexagonal microchannel is developed going from the equation proposed by Bejan. The effect of Cu, CuO, Al2O3 and TiO2 mixed with pure water inside the microchannel is evaluated via entropy generation analysis ...

The effects of transient radiant flow on pipe in contact with natural convection, for developed laminar flow of fluid with high Prandtl number, on enthalpy and entropy generation [PDF]

open access: yesChemical Review and Letters, 2019
Convection flow is passed in a pipe wall possessing radiation-convection, in order to find the best case with at least enthalpy and minimum entropy generation, through pipe wall having radiant flow.

Streaming generalized cross entropy [PDF]

open access: yesSoft Computing, 2019
We propose a new method to combine adaptive processes with a class of entropy estimators for the case of streams of data. Starting from a first estimation obtained from a batch of initial data, model parameters are estimated at each step by combining the prior knowledge with the new observation (or a block of observations).
