High-Temperature Mechanical Behavior of Cobalt-Free FeMnCrNi(Al) High-Entropy Alloys

open access: yesMetals, 2023
The high-temperature properties of new alloys need to be investigated to guide the hot working process. The temperature sensitivity of various microstructures of Fe45Mn15Cr15Ni25 and Fe35Mn15Cr15Ni25Al10 cobalt-free high-entropy alloys was investigated ...

On the entropy of couplings

open access: yesInformation and Computation, 2015
In this paper, some general properties of Shannon information measures are investigated over sets of probability distributions with restricted marginals. Certain optimization problems associated with these functionals are shown to be NP-hard, and their special cases are found to be essentially information-theoretic restatements of well-known ...

Entropy and Sorting

open access: yesJournal of Computer and System Sciences, 1992
AbstractWe reconsider the old problem of sorting under partial information, and give polynomial time algorithms for the following tasks: (1) Given a partial order P, find (adaptively) a sequence of comparisons (questions of the form, "is x < y?") which sorts ( i.e., finds an unknown linear extension of) P using O(log(e(P))) comparisons in worst case ...

Memory and Entropy

open access: yesEntropy, 2022
I study the physical nature of traces. Surprisingly, (i) systems separation with (ii) temperature differences and (iii) long thermalization times are sufficient conditions to produce macroscopic traces. Traces of the past are ubiquitous because these conditions are largely satisfied in our universe.

BD entropy and Bernis–Friedman entropy

open access: yesComptes Rendus. Mathématique, 2018
In this note, we propose in the full generality a link between the BD entropy introduced by D. Bresch and B. Desjardins for the viscous shallow-water equations and the Bernis–Friedman (called BF) dissipative entropy introduced to study the lubrication equations.

Entropy and Uncertainty [PDF]

open access: yesEntropy, 2008
We give a survey of the basic statistical ideas underlying the definition of entropy in information theory and their connections with the entropy in the theory of dynamical systems and in statistical mechanics.

Entropy-based semi-fragile watermarking of remote sensing images in the wavelet domain

open access: yes, 2019
This article presents a semi-fragile image tampering detection method for multi-band images. In the proposed scheme, a mark is embedded into remote sensing images, which have multiple frequential values for each pixel, applying tree-structured vector ...
