On algebras for interval-valued fuzzy logic
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM SISTEMAS E COMPUTAÇÃO, 2019-08-30)
This work aims to introduce other approaches to the interval-valued fuzzy logic. These
new approaches were inspired by Lodwick and Chalco’s works on constraint intervals. These
constraint intervals were used in this ...
Border detection in digital images: An approach by fuzzy numbers
(2007-12-01)
The purpose of this paper is to introduce a new approach for edge detection in gray shaded images. The proposed approach is based on the fuzzy number theory. The idea is to deal with the uncertainties concerning the gray ...
Pseudomonadic BL-algebras: an algebraic approach to possibilistic BL-logic
(Springer Berlin Heidelberg, 2019-02)
Fuzzy possibilistic logic is an important formalism for approximate reasoning. It extends the well-known basic propositional logic BL, introduced by Hájek, by offering the ability to reason about possibility and necessity ...
Monadic BL-algebras: The equivalent algebraic semantics of Hájek's monadic fuzzy logic
(Elsevier Science, 2017-08)
In this article we introduce the variety of monadic BL-algebras as BL-algebras endowed with two monadic operators ∀ and ∃. After a study of the basic properties of this variety we show that this class is the equivalent ...

Incluindo uma política de construção de objetos espaciais fuzzy no pacote FSR
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilEspecialização em Ciência de DadosUTFPR, 2021-12-30)
Currently, geoscientists have shown interest in modeling spatial phenomena with types of imprecise data, thus, fuzzy set theory has been used as a framework to model these types of imprecise data, through fuzzy spatial ...

A comparative study between two relaxed LMI-based fuzzy control designs
(2005-09-01)
A comparative study, with theoretical analysis and digital simulations, of two conditions based on LMI for the quadratic stability of nonlinear continuous-time dynamic systems, described by Takagi-Sugeno fuzzy models, are ...
