Evaluating investment potential tourism centers using integrated model of fuzzy Shannon’s entropy and fuzzy ARAS method [PDF]

open access: yesMuṭāli̒āt-i Mudīriyyat-i Gardishgarī, 2019
Prioritizing tourism poles can be a benchmark for centralizing as well as determining tourist attractions and moderating inequality between regions and is a step in formulating a tourism development plan.

A Note on Burg’s Modified Entropy in Statistical Mechanics

open access: yesMathematics, 2016
Burg’s entropy plays an important role in this age of information euphoria, particularly in understanding the emergent behavior of a complex system such as statistical mechanics. For discrete or continuous variable, maximization of Burg’s Entropy subject

On Computation of Degree-Based Entropy of Planar Octahedron Networks

open access: yesJournal of Function Spaces, 2022
Chemical graph theory is the combination of mathematical graph theory and chemistry. To analyze the biocompatibility of the compounds, topological indices are used in the research of QSAR/QSPR studies.

Exploring entropy measures in polymer graphs using logarithmic regression model

open access: yesScientific Reports
Graph Entropies, calculated from indices, quantify the structural information of chemical linkages and graphs using Shannon’s Entropy notion. This study investigates the chemical structures of polyester and polycarbonate polymers.

Extending the concept of entropy-negentropy for the assessment of ecological dominance and diversity at alpha, beta and gamma levels

open access: yesGeology, Ecology, and Landscapes, 2021
Several measures of ecological diversity have been defined at alpha, beta, and gamma levels and less attention has been paid to characterise their ecological dominance.

Monotonic Entropies

open access: yesScientific Annals of Computer Science
We introduce an axiomatization of entropy that generates, as special cases, novel entropy types. These entropies generalize Shannon’s entropy and allow the introduction of entropy for partitions of sets of objects located in metric spaces, and for ...

Increasing the Discriminatory Power of DEA Using Shannon’s Entropy

open access: yesEntropy, 2014
In many data envelopment analysis (DEA) applications, the analyst always confronts the difficulty that the selected data set is not suitable to apply traditional DEA models for their poor discrimination.

An Intrinsic Characterization of Shannon’s and Rényi’s Entropy

open access: yesEntropy
All characterizations of the Shannon entropy include the so-called chain rule, a formula on a hierarchically structured probability distribution, which is based on at least two elementary distributions.

The evaluation of the correlation between entropy and negentropy in the structure of a technical system

open access: yesMATEC Web of Conferences, 2017
The role of information uncertainty in the structure of a technical system is defined. The application possibility of the R. Hartley’s and C.E. Shannon’s approaches in determination of entropy and negentropy of structural content of the system are ...
