Optimistic multi-granulation roughness of intuitionistic fuzzy ideals based on soft relations over dual universes

Heliyon
The major point of proposed work is to study optimistic multi-granulation roughness of intuitionistic fuzzy ideals by using soft relations that is free from all the complications that challenged by many researchers.

Notes on locally internal uninorm on bounded lattices [PDF]

, 2017
summary:In the study, we introduce the definition of a locally internal uninorm on an arbitrary bounded lattice $L$. We examine some properties of an idempotent and locally internal uninorm on an arbitrary bounded latice $L$, and investigate relationship

A note on the fuzzy Xor

Annales Mathematicae Silesianae
In this paper we will try to answer what conditions must be met by the fuzzy Xor to be used for cryptographic purposes. We will also show that defining the fuzzy Xor using other fuzzy connectives is not suitable for this purpose.

Decision support system for selection of the appropriate tool of artificial intelligence using Diophantine spherical fuzzy normal interval-valued set

Journal of Taibah University for Science
Modern society employs an increasing number of robots, notably service robots. Robots will be able to handle everyday objects with simplicity, but only if they are collaborated with a planning and decision-making (DM) strategy that allows them to very ...

Some results in the level sets of some bipolar fuzzy relations

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this paper, some properties of a BPFR were studied. Also, level sets of BPFRs were studied with their properties. Some results were given and, in some cases, examples and counter-examples were constructed. In particular, we have shown that if a BPFR Q
