Join and meet operations for type-2 fuzzy sets with non-convex secondary memberships
In this paper we will present two theorems for the join and meet operations for general type-2 fuzzy sets with arbitrary secondary memberships, which can be non-convex and/or non-normal type-1 fuzzy sets. These results ... -
Linking mathematical morphology and L-fuzzy concepts
In this paper we study the relation between L-fuzzy morphology and L-fuzzy concepts over complete lattices. In particular, we show how the erosion and dilation operators of the former can be understood in terms of the ... -
Medical diagnosis of cardiovascular diseases using an interval-valued fuzzy rule-based classification system
Objective: To develop a classifier that tackles the problem of determining the risk of a patient of suffering from a cardiovascular disease within the next ten years. The system has to provide both a diagnosis and an ... -
A method for inference in approximate reasoning based on normal intuitionistic fuzzy sets
(Institute of Biophysics and Biomedical Engineering, Bulgarian Academy of Sciences, 1995) Artículo / ArtikuluaThis paper introduces a method of approximate inference which operates with nornal intuitionistic fuzzy. We give a definition of degree of compatibility between intuitionistic fuzzy sets and we present a method for the ... -
Multivalued contexts associated with criteria
We are interested in the study of L-fuzzy contexts taking into account different criteria. These contexts arise when we want to analyze the relationship between objects and attributes from different points of view. ... -
New measures for comparing matrices and their application to image processing
In this work we present the class of matrix resemblance functions, i.e., functions that measure the difference between two matrices. We present two construction methods and study the properties that matrix resemblance ... -
New trends on the numerical representability of semiordered structures
We introduce a survey, including the historical background, on di erent techniques that have recently been issued in the search for a characterization of the representability of semiordered structures, in the sense of ... -
On capacity planning for the GMPLS network control plane
This paper presents capacity planning rules for the control plane of all-optical networks featuring GMPLS and RSVP-TE as a connection setup protocol. As per RSVP standard, a refresh message mechanism is incorporated to ... -
On completeness and direction in fuzzy relational systems
The concepts of bounded subset, complete subset and directed subset, which are well known in the context of partially ordered sets (X, ≤), are extended in order to become applicable, with coherence, in fuzzy relational ... -
On contrast intensification operators and fuzzy equality relations
The class of contrast intensification operators is formally defined and its lattice structure studied. The effect of these operators in the referential classification derived from special kinds of fuzzy relations is also ... -
On the intuitionistic fuzzy relations
(Institute of Biophysics and Biomedical Engineering, Bulgarian Academy of Sciences, 1995) Artículo / ArtikuluaIntuitionistic fuzzy relations which generalize the already existing relations are introduced and their basic properties are shown. -
Online detection of pathological TCP flows with retransmissions in high-speed networks
Online Quality of Service (QoS) assessment in high speed networks is one of the key concerns for service providers, namely to detect QoS degradation on-the-fly as soon as possible and avoid customers’ complaints. In this ... -
Optical images-based edge detection in Synthetic Aperture Radar images
We address the issue of adapting optical images-based edge detection techniques for use in Polarimetric Synthetic Aperture Radar (PolSAR) imagery. We modify the gravitational edge detection technique (inspired by the Law ... -
Orderings in the referential set induced by intuitionistic fuzzy relation
(Institute of Biophysics and Biomedical Engineering, Bulgarian Academy of Sciences, 1995) Artículo / ArtikuluaIn this paper we present different orderings in the referential set induced by intuitionistic fuzzy relations of ordering. We can see how these induced orders justify the definition given of intuitionistic fuzzy antisymmetry ... -
Overtaker binary relations on complete completely distributive lattices related to the level sets of the L-fuzzy sets
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. -
Paired structures in knowledge representation
In this position paper we propose a consistent and unifying view to all those basic knowledge representation models that are based on the existence of two somehow opposite fuzzy concepts. A number of these basic models can ... -
Parametric families of fuzzy consequence operators
In a previous paper 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 of such ... -
A passive traffic algorithm for detecting unavailable periods in TCP services
This paper presents a simple passive algorithm to monitor service availability. The algorithm is based on packet counting over a passive traffic trace of a population of clients accessing servers of interest. The major ... -
Pointwise aggregation of maps: its structural functional equation and some applications to social choice theory
We study a structural functional equation that is directly related to the pointwise aggregation of a finite number of maps from a given nonempty set into another. First we establish links between pointwise aggregation and ... -
Posibles nuevas vías de investigación en teoría de la comunicación a través de modelos matemáticos: análisis topológico
Uno de los pocos puntos en los que los metodólogos de las ciencias sociales están de acuerdo es el divorcio existente entre trabajo teórico y trabajo metodológico en las prácticas sociales concretas. Por otro lado, para ...
