On Neutrosophic Vague Binary BZMZ^dM Sub-algebra of BZMZ^dM-algebra in Neutrosophic Vague Binary Sets [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
In Model theory, common algebraic structures found are Lattices and Boolean Algebras. In the broad field of research, various algebraic structures can be introduced for a set. BCK, BCI, BCH, BH etc. are some of them.

Classical and Fuzzy Two-Layered Modal Logics for Uncertainty: Translations and Proof-Theory

open access: yesInternational Journal of Computational Intelligence Systems, 2020
This paper is a contribution to the study of two distinct kinds of logics for modelling uncertainty. Both approaches use logics with a two-layered modal syntax, but while one employs classical logic on both levels and infinitely-many multimodal operators,

Comparing Circular Histograms by Using Modulo Similarity and Maximum Pair-Assignment Compatibility Measure

open access: yesInternational Journal of Computational Intelligence Systems, 2017
Histograms are an intuitively understandable tool for graphically presenting frequency data that is available for and useful in modern data-analysis, this also makes comparing histograms an interesting field of research.

The Calculus of Names—The Legacy of Jan Łukasiewicz

open access: yesAxioms
With his research on Aristotle’s syllogistic, Jan Łukasiewicz initiates the branch of logic known as the calculus of names. This field deals with axiomatic systems that analyse various fragments of the logic of names, i.e., that branch of logic that ...

A Logic for Dually Hemimorphic Semi-Heyting Algebras and its Axiomatic Extensions

open access: yesBulletin of the Section of Logic, 2022
The variety \(\mathbb{DHMSH}\) of dually hemimorphic semi-Heyting algebras was introduced in 2011 by the second author as an expansion of semi-Heyting algebras by a dual hemimorphism.

Aristotle’s Syllogistic as a Deductive System

open access: yesAxioms, 2020
Aristotle’s syllogistic is the first ever deductive system. After centuries, Aristotle’s ideas are still interesting for logicians who develop Aristotle’s work and draw inspiration from his results and even more from his methods.

Understanding Water System Manager's Motivations for and Their Perceived Benefits of Consolidation

open access: yesJAWRA Journal of the American Water Resources Association, Volume 61, Issue 6, December 2025.
ABSTRACT Across the United States, policymakers are busy developing incentive programs and mandatory policies to speed up adoption of consolidations and reduce the number of regulated water systems. Little attention, however, has been paid to why water system managers themselves, whose cooperation, if not leadership, is often required, pursue ...

Logiques dialogiques ‘multivalentes’

open access: yesPhilosophia Scientiæ, 2004
Aim of this paper is to show how so-called multi-valued logics can be formulated within the framework of Dialogical Logic. In order to formulate the particle rules for multi-valued logics the concept of different assertion modes is introduced.
