• #### Editorial [8th. Spanish Congress on Fuzzy Logic and Technology: selection of extended new versions of papers] ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Review
Open Access
• #### Fuzzy morphological operators in image processing ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2003)
Article
Open Access
First of all, in this paper we propose a family of fuzzy implication operators, which the generalised Luckasiewicz's one, and to analyse the impacts of Smets and Magrez properties on these operators. The result of this ...
• #### Generation of fuzzy mathematical morphologies ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2001)
Article
Open Access
Fuzzy Mathematical Morphology aims to extend the binary morphological operators to grey-level images. In order to define the basic morphological operations fuzzy erosion, dilation, opening and closing, we introduce a ...
• #### Intuitionistic fuzzy relations (Part II) Effect of Atanassov's operators on the properties of the intuitionistic fuzzy relations ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1995)
Article
Open Access
In this paper we study the effect of Atanassov's operator on the properties of properties reflexive, symmetric, antisymmetric, perfect antisymmetric and transitive intuitionistic fuzzy relations. We finish the paper analysing ...
• #### Intuitionistic fuzzy relations: (Part I) ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1995)
Article
Open Access
This paper introduces the concept of intuitionistic fuzzy relation. We also study the choice of t-norms and t-conorms which must be done in order that the composition of intuitionistic fuzzy relations fulfils the largest ...
• #### On Completeness and Direction in Fuzzy Relational Systems ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1998)
Article
Open Access
The concepts of bounded subset, complete subset and directed subset, wich are well known in the context of partialy ordered sets $(X,\leq )$, are extended in order to become appliable, with coherence, in fuzzy relational ...
• #### On contrast intensification operators and fuzzy equality relations ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2000)
Article
Open Access
The class of contrast intensification operators is formally defined and it's lattice structure studied. The effect of these operators in the referential classifications derived from special kinds of fuzzy relations is ...
• #### Overtaker binary relations on complete completely distributive lattices related to the level sets of the L-fuzzy Sets ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1994)
Article
Open Access
The class of overtaker binary relations associated with the order in a lattice is defined and used to generalize the representations of L-fuzzy sets by means of level sets or fuzzy points.
• #### Parametric families of fuzzy consequence operators ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2004)
Article
Open Access
In a previous paper ([6]) we explored the notion of coherent fuzzy consequence operator. Since we did not know of any example in the literature of non-coherent fuzzy consequence operator, we also showed several families ...
