F-homogeneous functions and a generalization of directional monotonicity
A function that takes (Formula presented.) numbers as input and outputs one number is said to be homogeneous whenever the result of multiplying each input by a certain factor (Formula presented.) yields the original output ... -
Factores de gestión del conocimiento en entidad pública del sector de tránsito y transporte
Desde una visión sistémica, la gestión del conocimiento afecta al proceso de toma de decisiones en las organizaciones que, en un entorno globalizado, deben plantear estrategias que posibiliten el incremento de la competitividad ... -
A fast SSVEP-based brain-computer interface
Literature of brain-computer interfacing (BCI) for steady-state visual evoked potentials (SSVEP) shows that canonical correlation analysis (CCA) is the most used method to extract features. However, it is known that CCA ... -
Fiber-optic brillouin distributed sensors: from dynamic to long-range measurements
This chapter focuses on Brillouin optical time-domain analysis (BOTDA) sensors because they are the most successful Brillouin distributed sensors (BDS) type in terms of performance and practical applications. Distributed ... -
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 ... -
Fireballs recorded between May and July 2021 by the Southwestern Europe Meteor Network
This work focuses on the analysis of the most remarkable bolides recorded over the Iberian Peninsula and neighboring areas in the framework of the Southwestern Europe Meteor Network (SWEMN) and the SMART project. These ... -
Flexible Bayesian P-splines for smoothing age-specific spatio-temporal mortality patterns
In this paper age-space-time models based on one and two-dimensional P-splines with B-spline bases are proposed for smoothing mortality rates, where both xed relative scale and scale invariant two-dimensional penalties ... -
A framework for active contour initialization with application to liver segmentation in MRI
Object segmentation is a prominent low-level task in image processing and computer vision. A technique of special relevance within segmentation algorithms is active contour modeling. An active contour is a closed contour ... -
A framework for general fusion processes under uncertainty modeling control, with an application in interval-valued fuzzy rule-based classification systems
La fusión de información es el proceso de combinar varios valores numéricos en uno solo que los represente. En problemas con algún tipo de modelado difuso, este proceso generalmente se realiza mediante funciones de fusión ... -
A framework for generalized monotonicity of fusion functions
The relaxation of the property of monotonicity is a trend in the theory of aggregation and fusion functions and several generalized forms of monotonicity have been introduced, most of which are based on the notion of ... -
FRIPON: a worldwide network to track incoming meteoroids
Context. Until recently, camera networks designed for monitoring fireballs worldwide were not fully automated, implying that in case of a meteorite fall, the recovery campaign was rarely immediate. This was an important ... -
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 ... -
From restricted equivalence functions on Ln to similarity measures between fuzzy multisets
Restricted equivalence functions are well-known functions to compare two numbers in the interval between 0 and 1. Despite the numerous works studying the properties of restricted equivalence functions and their multiple ... -
Las funciones docentes: su enseñanza y aprendizaje en los grados en maestro
La experiencia docente universitaria en los Grados en Maestro demuestra que existen obstáculos didácticos para la enseñanza y aprendizaje de las competencias asociadas a las funciones y prácticas docentes requeridas en la ... -
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 ... -
A fusion method for multi-valued data
In this paper we propose an extension of the notion of deviation-based aggregation function tailored to aggregate multidimensional data. Our objective is both to improve the results obtained by other methods that try to ... -
FUZZ-EQ: a data equalizer for boosting the discrimination power of fuzzy classifiers
The definition of linguistic terms is a critical part of the construction of any fuzzy classifier. Fuzzy partitioning methods (FPMs) range from simple uniform partitioning to sophisticated optimization algorithms. In this ... -
Fuzzy Arrovian theorems when preferences are strongly-connected
In this paper we study the aggregation of fuzzy preferences on non-necessarily finite societies. We characterize in terms of possibility and impossibility a family of models of strongly-connected preferences in which the ... -
A fuzzy association rule-based classifier for imbalanced classification problems
Imbalanced classification problems are attracting the attention of the research community because they are prevalent in real-world problems and they impose extra difficulties for learning methods. Fuzzy rule-based ... -
Fuzzy clustering to encode contextual information in artistic image classification
Automatic art analysis comprises of utilizing diverse processing methods to classify and categorize works of art. When working with this kind of pictures, we have to take under consideration different considerations compared ...
