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 ... -
Assessment of asymmetric leg loading before and after total hip arthroplasty using instrumented shoes
Background: Total hip arthroplasty is a successful surgical treatment in patients with osteoarthritis of the hip. Different questionnaires are used by the clinicians to assess functional capacity and the patient's pain, ... -
Atando cabos, contando circunferencias
Se presenta el análisis de los comportamientos en una cuestión de combinatoria en la Olimpiada Matemática de 2º ESO. El Enfoque ontosemiótico y la Teoría de situaciones didácticas en matemáticas constituyen el marco ... -
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 ... -
Chaos in the libration motion of an asymmetric non-rigid spacecraft
We study the libration motion dynamics of an asymmetric spacecraft in circular orbit under the influence of a gravity gradient torque -
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 ... -
Computation of greatest common divisor for the blind deconvolution of transient impulsive signals
We propose a new blind deconvolution method for transient impulsive signals in a single input – multiple output (SIMO) system. The method exploits the data redundancy inherent to SIMO multichannel systems to obtain an ... -
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 ... -
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 ... -
Desarrollo del pensamiento combinatorio: evaluación y materiales
Profesores en formación analizan en una tarea de recuento la pertinencia de distintos esquemas de corrección (Wilhelmi, Belletich, Lasa y Reina, 2013). En criterio general en todos ellos es: de ejecución máxima en una ... -
Design of low-cost smart accelerometers
The goal of this project is to design a low-cost smart accelerometer, making use of a piezoelectric element as basic sensing material, and adding a mixed-mode conditioning circuit. -
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 ... -
Distribution patterns of infection with multiple types of human papillomaviruses and their association with risk factors
Background: Infection with multiple types of human papillomavirus (HPV) is one of the main risk factors associated with the development of cervical lesions. In this study, cervical samples collected from 1, 810 women with ... -
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 ... -
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 ... -
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 ... -
Evaluación de respuestas a una tarea de recuento
La transposición didáctica explica los procesos adaptativos del saber en la escuela. Los desarrollos didácticos han puesto el énfasis en el modo en que estos procesos condicionan las intervenciones razonadas del docente ... -
An evaluation of the 30-s chair stand test in older adults: frailty detection based on kinematic parameters from a single inertial unit
Background: A growing interest in frailty syndrome exists because it is regarded as a major predictor of co-morbidities and mortality in older populations. Nevertheless, frailty assessment has been controversial, particularly ... -
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 % ...
