Curve-based monotonicity: a generalization of directional monotonicity
In this work we propose a generalization of the notion of directional monotonicity. Instead of considering increasingness or decreasingness along rays, we allow more general paths defined by curves in the n-dimensional ... -
d-Choquet integrals: Choquet integrals based on dissimilarities
(Elsevier, 2020) Artículo / ArtikuluaThe paper introduces a new class of functions from [0,1]n to [0,n] called d-Choquet integrals. These functions are a generalization of the 'standard' Choquet integral obtained by replacing the difference in the definition ... -
Decomposition and arrow-like aggregation of fuzzy preferences
We analyze the concept of a fuzzy preference on a set of alternatives, and how it can be decomposed in a triplet of new fuzzy binary relations that represent strict preference, weak preference and indifference. In this ... -
Desarrollo del razonamiento algebraico elemental mediante tareas de recuento con patrones
Las tareas de recuento con patrones son un contexto privilegiado para el desarrollo del razonamiento algebraico. La complejidad ontosemiótica de las tareas permite identificar procesos de estudio para hacer progresar el ... -
Deterministic propagation modeling for intelligent vehicle communication in smart cities
Vehicular Ad Hoc Networks (VANETs) are envisaged to be a critical building block of Smart Cities and Intelligent Transportation System (ITS) where applications for pollution, congestion reduction, vehicle mobility improvement, ... -
Dynamics in the charged restricted circular three-body problem
The existence and stability of periodic solutions for different types of perturbations associated to the Charged Restricted Circular Three Body Problem (shortly, CHRCTBP) is tackled using reduction and averaging theories ... -
Effect of thermal stress on tissue ultrastructure and metabolite profiles during initiation of Radiata pine somatic embryogenesis
Climate change will inevitably lead to environmental variations, thus plant drought tolerance will be a determinant factor in the success of plantations and natural forestry recovery. Some metabolites, such as soluble ... -
Effects of a soft-core coulomb potential on the dynamics of a hydrogen atom near a metal surface
(Elsevier, 2019) Artículo / ArtikuluaThe goal of this paper is to investigate the effects that the replacement of the Coulomb potential by a soft-core Coulomb potential produces in the classical dynamics of a perturbed Rydberg hydrogen atom. As example, we ... -
Efficient SSP low-storage Runge-Kutta methods
In this paper we study the efficiency of Strong Stability Preserving (SSP) Runge-Kutta methods that can be implemented with a low number of registers using their Shu-Osher representation. SSP methods have been studied ... -
Embeddability of ℓp and bases in Lipschitz free p-spaces for 0 < p ≤ 1
(Elsevier, 2020) Artículo / ArtikuluaOur goal in this paper is to continue the study initiated by the authors in of the geometry of the Lipschitz free p-spaces over quasimetric spaces for 0 < p ≤ 1, denoted Fp(M). Here we develop new techniques to show that, ... -
Enhancing sensorimotor BCI performance with assistive afferent activity: an online evaluation
An important goal in Brain-Computer Interfacing (BCI) is tofind and enhance procedural strategies for users for whom BCI control is not sufficiently accurate. To address this challenge, we conducted offline analyses and ... -
Epidemiology of non-steroidal anti-inflammatory drugs consumption in Spain. The MCC-Spain study
Background: Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used despite their risk of gastrointestinal bleeding or cardiovascular events. We report the profile of people taking NSAIDs in Spain, and we include ... -
An evolutionary underbagging approach to tackle the survival prediction of trauma patients: a case study at the Hospital of Navarre
Survival prediction systems are used among emergency services at hospitals in order to measure their quality objectively. In order to do so, the estimated mortality rate given by a prediction model is compared with the ... -
Experimental investigation of the particle oscillation instability in a single-axis acoustic levitator
Single-axis acoustic levitators are employed in biomedicine, chemistry and physics experiments due to their ability to trap in mid-air objects of a wide range of materials and sizes. Although this type of levitator has ... -
Filling missing data and smoothing altered data in satellite imagery with a spatial functional procedure
Outliers and missing data are commonly found in satellite imagery. These are usually caused by atmospheric or electronic failures, hampering the correct monitoring of remote-sensing data. To avoid distorted data, we propose ... -
From fuzzy sets to interval-valued and Atanassov intuitionistic fuzzy sets: a unified view of different axiomatic measures
We examine a broad collection of axiomatic definitions from various and diverse contexts, within the domain of fuzzy sets. We evaluate their respective extensions to the case of interval-valued fuzzy sets and intuitionistic ... -
Funções de agregação baseadas em integral de Choquet aplicadas em redimensionalização de imagens
The increasing data volume, coupled with the high complexity of these data, has generated the need to develop increasingly efficient knowledge extraction techniques, both in computational cost and precision. Most of the ... -
Geometric multigrid methods for Darcy–Forchheimer flow in fractured porous media
(Elsevier, 2019) Artículo / ArtikuluaIn this paper, we present a monolithic multigrid method for the efficient solution of flow problems in fractured porous media. Specifically, we consider a mixed-dimensional model which couples Darcy flow in the porous ... -
Geometrical aggregation of finite fuzzy sets
A fuzzy set on a finite universe can be interpreted as a vector in a unit cube. This gives rise to a huge variety of approaches in order to aggregate finite fuzzy sets or to modify a given one. We analyze several geometrical ... -
