A large scale screening study with a SMR-based BCI: Categorization of BCI users and differences in their SMR activity
Brain-Computer Interfaces (BCIs) are inefficient for a non-negligible part of the population, estimated around 25%. To understand this phenomenon in Sensorimotor Rhythm (SMR) based BCIs, data from a large-scale screening ... -
Motor abnormalities and cognitive impairment in first-episode psychosis patients, their unaffected siblings and healthy controls
Motor abnormalities (MAs) may be already evidenced long before the beginning of illness and are highly prevalent in psychosis. However, the extent to which the whole range of MAs are related to cognitive impairment ... -
Weightable quasi-metrics related to fuzzy sets
We show that the definition of a fuzzy set is directly related to the existence of a weightable quasi-metric on a universe. This relationship is also explored in terms of functional equations coming either from the membership ... -
Desarrollo de la competencia de análisis ontosemiótico de futuros profesores de matemáticas
Una enseñanza adecuada de las matemáticas requiere el conocimiento y la competencia de los profesores para identificar la variedad de objetos y significados involucrados en la resolución de tareas escolares. En este ... -
On the structure of acyclic binary relations
We investigate the structure of acyclic binary relations from different points of view. On the one hand, given a nonempty set we study real-valued bivariate maps that satisfy suitable functional equations, in a way that ... -
Binary relations coming from solutions of functional equations: orderings and fuzzy subsets
We analyze the main properties of binary relations, defined on a nonempty set, that arise in a natural way when dealing with real-valued functions that satisfy certain classical functional equations on two variables. We ... -
Normas epistémicas en la formación musical del maestro de educación primaria
En España, la actual reforma educativa está forzando a las universidades a ajustar la formación inicial docente porque el nuevo sistema escolar orienta el currículo hacia la formación por competencias. Esta investigación ... -
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 ... -
An algorithm for group decision making using n -dimensional fuzzy sets, admissible orders and OWA operators
In this paper we propose an algorithm to solve group decision making problems using n -dimensional fuzzy sets, namely, sets in which the membership degree of each element to the set is given by an in- creasing tuple of n ... -
Orness for idempotent aggregation functions
Aggregation functions are mathematical operators that merge given data in order to obtain a global value that preserves the information given by the data as much as possible. In most practical applications, this value is ... -
Some characterizations of lattice OWA operators
Ordered Weighted Averaging (OWA) operators are a family of aggregation which fusion data. If the data are real numbers, then OWA operators can be characterized either as an special kind of Choquet integral or simply as an ... -
La educación musical en la formación básica en España. El problema de la dispersión curricular
En España la Educación Artística pierde su carácter obligatorio en Educación Primaria con la entrada en vigencia de la Ley Orgánica para la Mejora de la Calidad Educativa [LOMCE], relegando la decisión curricular a ... -
Interval-valued Atanassov intuitionistic OWA aggregations using admissible linear orders and their application to decision making
Based on the definition of admissible order for interval-valued Atanassov intuitionistic fuzzy sets, we study OWA operators in these sets distinguishing between the weights associated to the membership and those associated ... -
Ensembles of adaptive spatial filters increase BCI performance: an online evaluation
Objective: In electroencephalographic (EEG) data, signals from distinct sources within the brain are widely spread by volume conduction and superimposed such that sensors receive mixtures of a multitude of signals. This ... -
Niveles de algebrización de las prácticas matemáticas escolares. Articulación de las perspectivas ontosemiótica y antropológica
En el marco del enfoque ontosemiótico del conocimiento y la instrucción matemáticos se ha propuesto una caracterización del razonamiento algebraico en Educación Primaria basada en la distinción de tres niveles de ... -
Frailty assessment based on trunk kinematic parameters during walking
Background: Physical frailty has become the center of attention of basic, clinical and demographic research due to its incidence level and gravity of adverse outcomes with age. Frailty syndrome is estimated to affect 20 % ... -
Comparison meaningful operators and ordinal invariant preferences
The existence of a continuous and order-preserving real-valued function, for the class of continuous and ordinal invariant total preorders, defined on the Banach space of all bounded real-valued functions, which are in ... -
Construction of admissible linear orders for interval-valued Atanassov intuitionistic fuzzy sets with an application to decision making
In this work we introduce a method for constructing linear orders between pairs of intervals by using aggregation functions. We adapt this method to the case of interval-valued Atanassov intuitionistic fuzzy sets and we ... -
Evaluación de conocimientos didáctico-matemáticos sobre razonamiento algebraico elemental de futuros maestros
Diferentes estudios sugieren la necesidad de incorporar desde edades tempranas el razonamiento algebraico elemental, que en las propuestas curriculares clásicas se inicia en la Educación Secundaria Obligatoria. En este ... -
Diseño de un cuestionario para evaluar conocimientos didáctico-matemáticos sobre razonamiento algebraico elemental
La promoción del pensamiento algebraico en alumnos de primaria requiere implementar acciones formativas específicas para los profesores, lo que a su vez implica elaborar instrumentos de evaluación del estado de sus ...
