Triangular Dense Fuzzy Neutrosophic Sets [PDF]

open access: yesNeutrosophic Sets and Systems, 2016
. In this study, we introduce the concept of denser property in fuzzy membership function used in neutrosophic sets. We present several new definitions and study their properties.

A Unified Framework for the Upper and Lower Discretizations of Fuzzy Implications

open access: yesAxioms
In this paper, we investigate the discretization of fuzzy implications using rounding functions. Our discretization method is a unified framework of the upper and lower discretization methods of Munar-Covas et al.

Modal Type of Weak Intuitionistic Fuzzy Implications Generated by the Operation Δ

open access: yesCybernetics and Information Technologies, 2021
In 2020 L. Atanassova has been introduced the new operation Δ over intuitionistic fuzzy sets and over intuitionistic fuzzy pairs. Some of its properties have been studied in 2021 from L. Atanassova and P. Dworniczak. In 2021 L.

Learning fuzzy inference systems using an adaptive membership function scheme

open access: yes, 1996
An adaptive membership function scheme for general additive fuzzy systems is proposed in this paper. The proposed scheme can adapt a proper membership function for any nonlinear input-output mapping, based upon a minimum number of rules and an initial ...

Supplier Assessment and Selection Using Fuzzy Analytic Hierarchy Process in a Steel Manufacturing Company [PDF]

open access: yes, 2013
Every organization needs suppliers and no organization can exist without suppliers. Therefore, the organizations approach to suppliers and the selection of the appropriate supplier, its acquisition processes and policies, and its relationships with ...

An Algorithm for Producing Fuzzy Implications via Conical Sections

open access: yesAlgorithms
In the present study, a novel parametric family of fuzzy implications is introduced and its properties are examined. The parametric family of implications is produced only via a fuzzy negation.

S-Implications on Complete Lattices and the Interval Constructor

open access: yesTrends in Computational and Applied Mathematics, 2008
The aim of this work is to present an approach of interval fuzzy logic based on complete lattices. In particular, we study the extensions of the notions of t-conorms, fuzzy negations and S-implication, from the unit interval to arbitrary complete ...

Some Properties of the Extended Threshold Generated Implications

open access: yesFuzzy Information and Engineering
Fuzzy implications play an important role in both approximating reasoning and fuzzy control, and there are many generation methods for fuzzy implications for various applications. The extended threshold generation method for fuzzy implications can induce

A novel study of properties, functional equations and families of fuzzy implications through strict monotonicity [PDF]

open access: yes
summary:It is well known that monotonicity has been an important defining criterion for fuzzy logic connectives, such as fuzzy negations, t-norms, t-conorms and fuzzy implications.

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

open access: yesFEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status
