Identification of Types of Pollution That Mostly Affect the Environment by Using Picture Fuzzy Soft Aggregation Operators

IEEE Access
The release of harmful materials into the environment is called pollution and the harmful materials are called pollutants. There are four basic categories of pollution: land, water, noise, and air pollution.

Fuzzy algebraic hyperstructures: an introduction

, 2015
This book is intended as an introduction to fuzzy algebraic hyperstructures. As the first in its genre, it includes a number of topics, most of which reflect the authors’ past research and thus provides a starting point for future research directions ...

Matrix formulation of fuzzy rule-based systems [PDF]

, 1996
In this paper, a matrix formulation of fuzzy rule based systems is introduced. A gradient descent training algorithm for the determination of the unknown parameters can also be expressed in a matrix form for various adaptive fuzzy networks.

On Algebraic Structures of Bipolar Valued Fuzzy Sets

, 2019
The aim of this study is to observe the some algebraic structures of a bipolar valued fuzzy set. We introduce the notion of bipolar fuzzy submodule of a given classical module and study fundamental properties and characterizations.

Algebraic structures generalizing fuzzy implications

Liberal Arts Innovation Center
Fuzzy logic is a many-valued logical system with truth values within the subset[0, 1] of real numbers. The set[0, 1] is a totally ordered set, and thus it has limitations in application to various real-life examples. Therefore, generalized many-valued logical systems that can be applied to more various examples of real life need to be studied and their

Quantales for Fuzzy Sets and Relations of Higher Types

Mathematics
In this paper, we open up more possibilities to define higher types of fuzzy sets in a mixed way. In doing so, we show that there are essentially two alternative definitions for fuzzy sets of higher types, one of which is widely adopted in the literature,

LEVEL SOFT SEMIRING FROM FUZZY SUBSEMIRING

Barekeng
This paper introduces the concept of a level soft set and a level soft semiring over a semiring derived from a fuzzy subsemiring. By employing the level subset approach of fuzzy sets, we construct soft structures whose images form subsemirings of the ...

Algebraic structures from quantum and fuzzy logics.

, 2016
This thesis concerns the wide research area of logic. In particular, the first part is devoted to analyze different kinds of relational systems (orthogonal and residuated), by investigating the properties of the algebras associated to them. The second part is focused on algebras of logic, in particular, the relationship between prominent quantum and ...

A new approach to adaptive fuzzy control: the controller output error method [PDF]

, 1997
The controller output error method (COEM) is introduced and applied to the design of adaptive fuzzy control systems. The method employs a gradient descent algorithm to minimize a cost function which is based on the error at the controller output.
