Mathematical content on STEM activities
In this paper, a number of STEM educational proposals are systematically analyzed from the lens of mathematics education. An extensive innovation project was implemented during the 2019/2020 academic year in a pilot study ... -
MEANSP: How many channels are needed to predict the performance of a SMR-Based BCI?
Predicting whether a particular individual would reach an adequate control of a Brain-Computer Interface (BCI) has many practical advantages. On the one hand, participants with low predicted performance could be trained ... -
Measures of embedding for interval-valued fuzzy sets
Interval-valued fuzzy sets are a generalization of classical fuzzy sets where the membership values are intervals. The epistemic interpretation of interval-valued fuzzy sets assumes that there is one real-valued membership ... -
Medicago sativa and Medicago truncatula show contrasting root metabolic responses to drought
Drought is an environmental stressor that affects crop yield worldwide. Understandingplant physiological responses to stress conditions is needed to secure food in futureclimate conditions. In this study, we applied a ... -
Microfluidic platform using focused ultrasound passing through hydrophobic meshes with jump availability
Applications in chemistry, biology, medicine, and engineering require the large-scale manipulation of a wide range of chemicals, samples, and specimens. To achieve maximum efficiency, parallel control of microlitre droplets ... -
Minimal determinization algorithm for fuzzy automata
The determinization of fuzzy automata is a well-studied problem in theoretical computer science celebrated for its practical applications. Indeed, in the fields of fuzzy discrete event systems, fault diagnosis, clinical ... -
Mixed-dimensional geometric multigrid methods for single-phase flow in fractured porous media
This paper deals with the efficient numerical solution of single-phase flow problems in fractured porous media. A monolithic multigrid method is proposed for solving two-dimensional arbitrary fracture networks with vertical ... -
Mixture functions and their monotonicity
We consider mixture functions, which are a type of weighted averages for which the corresponding weights are calculated by means of appropriate continuous functions of their inputs. In general, these mixture function need ... -
MmWave channel stationarity analysis of V2X communications in an urban environment
Vehicular communication channels are subject to high nonstationarity mainly characterized by the scatterers’ and/or transceivers’ high mobility. In this sense, this letter presents a characterization of the channel ... -
Modeling of noisy acceleration signals from quasi-periodic movements for drift-free position estimation
We present a novel approach to drift-free position estimation from noisy acceleration signals which often arise from quasi-periodic small-amplitude body movements. In contrast to the existing methods, this data-driven ... -
Un modelo para predecir cuántas camas UCI harán falta durante cada oleada
La crisis financiera mundial de 2008 puso de moda en España el término económico “prima de riesgo”, hasta entonces desconocido. Del mismo modo, la pandemia ha popularizado expresiones y términos como “doblar la curva”, ... -
Modelos fantásticos: los secretos del software dinámico
El Grupo de investigación en Didáctica de las matemáticas de la UPNA trabaja desde 2009 en el diseño de modelos dinámicos y en su implementación en situaciones de enseñanza y aprendizaje de las matemáticas. En este artículo, ... -
Moderate deviation and restricted equivalence functions for measuring similarity between data
In this work we study the relation between moderate deviation functions, restricted dissimilarity functions and restricted equivalence functions. We use moderate deviation functions in order to measure the similarity or ... -
Moisture content estimation models of flour matrices in the 67-110 GHz frequency range using a nondestructive and contactless monitoring system
This work addresses the lack of moisture content estimation models for food products in the millimeter-wave frequency range and showcases the potential of this range for designing compact, cost-effective, and in-line food ... -
Momentos de exploración e ilustración en la determinación de circunferencias en futuros docentes de educación secundaria
Se analiza la actividad matemática de estudiantes del Máster Universitario en Profesorado de Educación Secundaria, especialidad en Matemáticas, en una situación didáctica destinada al estudio de circunferencias. En las ... -
Monitoring rainfed alfalfa growth in semiarid agrosystems using Sentinel-2 imagery
The aim of this study was to assess the utility of Sentinel-2 images in the monitoring of the fractional vegetation cover (FVC) of rainfed alfalfa in semiarid areas such as that of Bardenas Reales in Spain. FVC was sampled ... -
Motor-imagery-based brain-computer interface using signal derivation and aggregation functions
Brain Computer Interface (BCI) technologies are popular methods of communication between the human brain and external devices. One of the most popular approaches to BCI is Motor Imagery (MI). In BCI applications, the ... -
Multi-criteria simulation-optimization analysis of usage of automated parcel lockers: a practical approach
The rapid growth of electronic commerce is having an impact on the way urban logistics are organized. In metropolitan settings, the last-mile delivery problem, i.e., the problem regarding the final stage of delivering a ... -
A multi-splitting method to solve 2D parabolic reaction-diffusion singularly perturbed systems
(Elsevier, 2023) Artículo / ArtikuluaIn this paper we design and analyze a numerical method to solve a type of reaction-diffusion 2D parabolic singularly perturbed systems. The method combines the central finite difference scheme on an appropriate piecewise ... -
The multidimensional conception of social exclusion and the aggregation dilemma: a solution proposal based on multiple correspondence analysis
The main objective of the article is twofold. On the one hand, it aims to offer a critical analysis of the different operationalizations of the concept of social exclusion at the international level, including reflection ...
