An Original Notion to Find Maximal Solution in the Fuzzy Neutrosophic Relation Equations (FNRE) with Geometric Programming (GP) [PDF]

open access: yesNeutrosophic Sets and Systems, 2015
In this paper, finding - a maximal solution is introduced to (𝑉,𝛬) fuzzy neutrosophic relation equation. the notion of fuzzy relation equation was first investigated by Sanchez in 1976, while Florentin Smarandache put forward a fuzzy neutrosophic ...

Fire risk modeling and prediction in district three of Neka-Zalemroud forest, using Geographical Information System [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2013
The aim of the study was to predict future fires at District Three of Neka-Zalemroud Forests, using fire risk modeling. Fuzzy Analytical Hierarchy (AHP) method was used to weight the effective fire factors, then map of each factor was developed for ...

New Relation-Theoretic Fixed Point Theorems in Fuzzy Metric Spaces with an Application to Fractional Differential Equations

open access: yesAxioms, 2022
In this paper, we introduce the notion of fuzzy R−ψ−contractive mappings and prove some relevant results on the existence and uniqueness of fixed points for this type of mappings in the setting of non-Archimedean fuzzy metric spaces. Several illustrative

On Measures of Fuzziness of Solutions of Composite Fuzzy Relation Equations

open access: yesIFAC Proceedings Volumes, 1983
In this paper we study the solutions of a max-min fuzzy relation equation of Sanchez (1976) by determining ones which have the greatest energy measure and the smallest entropy measure of fuzziness.

Max-Min Fuzzy Relation Equations for a Problem of Spatial Analysis

open access: yesRatio Mathematica, 2016
We implement an algorithm that uses a system of max-min fuzzy  relation equations (SFRE) for solving a problem of spatial analysis. We integrate this algorithm in a Geographical information Systems (GIS) tool.

On the fuzziness of solutions of -fuzzy relation equations on finite spaces

open access: yesFuzzy Sets and Systems, 1983
Let be the set of solutions of a -fuzzy relation equation defined on finite spaces. In this paper we use some algorithms, already introduced in our foregoing work, in order to determine some relations of which have a minimal value of fuzziness measure.

On Solution of Min-Max Composition Fuzzy Relational Equation

open access: yesمجلة بغداد للعلوم, 2007
In this paper, Min-Max composition fuzzy relation equation are studied. This study is a generalization of the works of Ohsato and Sekigushi. The conditions for the existence of solutions are studied, then the resolution of equations is discussed.

Radial acceleration relation from ultra-light scalar dark matter

open access: yesPhysics Letters B, 2019
We show that ultra-light scalar dark matter (fuzzy dark matter) in galaxies has a quantum mechanical typical acceleration scale about 10−10ms−2, which leads to the baryonic Tully-Fisher relation.
