Experiencias de lenguaje visual e interacción gráfica para soporte al aprendizaje
(Universitat Politècnica de Catalunya. Escola Tècnica Superior d'Arquitectura del Vallès, 2006-09)
Article
Accés obertEsta comunicación describe una de las líneas de trabajo que se vienen desarrollando actualmente en el centro CAIRAT de la E.T.S.A.V. (UPC). Ésta consiste en la elaboración de material docente de soporte destinado a las ... -
Extensionality based approximate reasoning
(1998-06)
Article
Accés restringit per política de l'editorialThe aim of this paper is to analyze Approximate Reasoning (AR) through extensionality with respect to the natural T-indistinguishability operator, by considering the indistinguishability level between fuzzy sets as a formal ... -
Extensionality with respect to indistinguishability operators
(2018-04-01)
Article
Accés obertExtensionality is explored form different points of view. Extensional fuzzy subsets from a fuzzy equivalence relation E are considered as observable subsets with respect to the granularity generated by E. Interestingly, ... -
Fuzzy actions
(2017-01-01)
Article
Accés obertThis paper generalizes (fuzzifies) actions of a monoid or group on a set to deal with situations where imprecision and uncertainty are present. Fuzzy actions can handle the granularity of a set or even create it by defining ... -
G-shells:flat collapsible geodesic mechanisms for gridshells
(International Centre for Numerical Methods in Engineering (CIMNE), 2019)
Comunicació de congrés
Accés obertWe present G-shells, a new strategy for deployable elastic gridshells developed from an initially flat and compact geodesic mechanism. The one-degree of freedom mechanism evolves from its initially flat state into a geodesic ... -
Generation and Characterization of Fuzzy T-preorders
(2015-05-28)
Article
Accés obertThis article studies T-preorders that can be generated in a natural way by a single fuzzy subset. These T-preorders are called one-dimensional and are of great importance, because every T-preorder can be generated by ... -
Indistinguishability operators with respect to different t-norms
(2012-04)
Article
Accés restringit per política de l'editorialAn isomorphism f between two continuous Archimedean t-norms T and T′ transforms a T-indistinguishability operator E into a T′-indistinguishability operator f ∘ E and many interesting properties of E are transfered to f ∘ ... -

On the degree of transitivity of a fuzzy relation
(2021-01-01)
Article
Accés obertConsidering a family generated from a t-norm T, the degree of T-transitivity of a fuzzy relation R is revisited and proved to coincide with the greatest c for which R is -transitive. This fact gives rise to the study of ... -
On the relationship between fuzzy subgroups and indistinguishability operators
(2018-09-06)
Article
Accés obertFuzzy subgroups are revisited considering their close relationship with indistinguishability operators (fuzzy equivalences) invariant under translations. Different ways to obtain new fuzzy subgroups from a given one are ... -
On the relationship between T-transitivity and approximate equality
(2003-01)
Article
Accés restringit per política de l'editorialThe paper discusses the suitability of T-transitivity for modelling approximate equality. It explains how T-transitivity, a property suitable for modelling vagueness, can still be used to handle the imprecision inherent ... -
On the unidimensional fuzzy equivalence relations
(Wiley InterScience, 1999-09)
Article
Accés restringit per política de l'editorialThe dimension of a fuzzy equivalence relation is the minimum number of fuzzy sets needed to generate it. A general theorem is proved that characterizes unidimensional fuzzy equivalence relations. The multidimensional case ... -
One-dimensional T-preorders
(IOS Press, 2014)
Text en actes de congrés
Accés obertThis paper studies T-preorders by using their Representation Theorem that states that every T-preorder on a set X can be generated in a natural way by a family of fuzzy subsets of X. Especial emphasis is made on the study ... -
Operadores de T-indistinguibilidad respecto a sumas ordinales
(2014)
Text en actes de congrés
Accés obertEn este trabajo se estudia la clase de operadores de T-indistinguibilidad con T una suma ordinal. Mostramos que estos operadores de T-indistinguibilidad pueden pensarse como familias de operadores de indistinguibilidad ... -
Powers with respect to t-norms and t-conorms and Aggregation Functions
(Springer, 2016)
Capítol de llibre
Accés restringit per política de l'editorialAggregation functions A stable with respect to powers of t-norms and t-conorms (i.e.: satisfying A(x^{(r)},y^{(r)})=(A(x,y))^{(r)}) where x^{(r)} is the r-th power of x \in [0,1] with respect to a t-norm or t-conorm) are ... -

Reduction of attributes in averaged similarities
(2018-02-01)
Article
Accés obertSimilarity Relations may be constructed from a set of fuzzy attributes. Each fuzzy attribute generates a simple similarity, and these simple similarities are combined into a complex similarity afterwards. The Representation ... -
