Hidden modalities in algebras with negation and implication [PDF]

open access: yes, 2013
Lukasiewicz 3-valued logic may be seen as a logic with hidden truthfunctional modalities de ned by A := :A ! A and A := :(A ! :A). It is known that axioms (K), (T), (B), (D), (S4), (S5) are provable for these modalities, and rule (RN) is admissible. We

Edelstein Fixed Point Theorem in Neutrosophic Metric Spaces With an Application to an SIR‐Type Epidemic Model

open access: yesInternational Journal of Differential Equations, Volume 2026, Issue 1, 2026.
In this paper, utilizing the concept of neutrosophic metric spaces proposed by Kirisci and Simsek, we establish a fixed point theorem of Edelstein type within this framework. A numerical example is provided to illustrate the validity of the main result. Furthermore, we present an application to a general SIR‐type epidemic model.

A Fourth Order Finite Difference Scheme for the Solution of Intuitionistic Fuzzy Hyperbolic Partial Differential Equation

open access: yesFuzzy Information and Engineering
This paper aims to develop a fourth order fuzzy finite difference scheme to solve an intuitionistic fuzzy hyperbolic partial differential equation. The initial and boundary conditions of the intuitionistic fuzzy hyperbolic partial differential equation ...

A Solution of an Intuitionistic Fuzzy Time‐Fractional Diffusion Equation Using a Modified Explicit Finite Difference Scheme

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
The utilization of fuzzy fractional partial differential equations has turned into a practical tool for modeling real‐life phenomena because they offer a compact framework for modeling complex phenomena with uncertainty, providing insights and reflecting on systems that classical models cannot adequately get.

Neutrality and Many-Valued Logics [PDF]

open access: yes, 2007
In this book, we consider various many-valued logics: standard, linear, hyperbolic, parabolic, non-Archimedean, p-adic, interval, neutrosophic, etc. We survey also results which show the tree different proof-theoretic frameworks for many-valued logics, e.

Decision making in reinsurance with induced OWA operators and Minkowski distances [PDF]

open access: yes, 2016
The decision to choose a reinsurance program has many complexities because it is difficult to simultaneously achieve high levels in different optimal criteria including maximum gain, minimum variance, and probability of ruin.

Location Planning for Constructing New Emergency Medical Services: A Case Study

open access: yesJournal of Engineering, Volume 2026, Issue 1, 2026.
Emergency medical services (EMSs) are an efficient and effective system created to provide pre‐hospital care so as to minimize physical harm in the event of an emergency like Corona pandemic. The system is aimed at providing a rapid response to save patients’ lives and, if necessary, to transfer them to pandemic treatment centers.

Gaussian single-valued neutrosophic numbers and its application in multi-attribute decision making [PDF]

open access: yesNeutrosophic Sets and Systems, 2018
The fuzzy set and intuitionistic fuzzy set are two useful mathematical tool for dealing with impression and uncertainty. However sometimes these theories may not suffice to model indeterminate and inconsistent information encountered in real world.
