Entropy Decoding the Fundamental Law of Phase Competition in Glass Formation [PDF]

open access: yesAdvanced Science
The quest to understand the fundamentals of optimal glass‐forming compositions in multi‐component alloys has long been challenging. To gain insights into the mechanism, a systematic study of glass compositions is conducted using a new strategy of entropy

Learning Continuous Decomposable Models Using Mutual Information and Statistical Copulas [PDF]

open access: yesEntropy
Learning dependence graphs from multivariate continuous data is challenging when marginal distributions are heterogeneous, since likelihood-based nonparametric scores can be sensitive to smoothing choices and can confound marginal irregularities ...

Analysis of entropies based on empirical mode decomposition in amnesic mild cognitive impairment of diabetes mellitus [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2015
EEG characteristics that correlate with the cognitive functions are important in detecting mild cognitive impairment (MCI) in T2DM. To investigate the complexity between aMCI group and age-matched non-aMCI control group in T2DM, six entropies combining ...

Effect of d-Dimensional Re-orderings on Lossless Compression of Radio-Astronomy and Digital Elevation Data

open access: yesIEEE Access, 2021
For multidimensional data, Space-Filling Curves (SFCs) have been used to improve the execution time of spatial data queries. However, their effect on compression, when used to reorder the uncompressed values, is known to a lesser extent.

A Fuzzy Entropy-Based Group Consensus Measure for Financial Investments

open access: yesMathematics, 2023
This study presents a novel, fuzzy entropy-based approach to the measurement of consensus in group decision making. Here, the basic assumption is that the decision inputs are the ‘yes’ or ‘no’ votes of group members on a financial investment that has a ...

Entropy Generation through Non-Equilibrium Ordered Structures in Corner Flows with Sidewall Mass Injection

open access: yesEntropy, 2016
Additional entropy generation rates through non-equilibrium ordered structures are predicted for corner flows with sidewall mass injection. Well-defined non-equilibrium ordered structures are predicted at a normalized vertical station of approximately ...

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 ...
