Dificultades para Codificar, Relacionar y Categorizar Problemas Verbales Algebraicos: dos estudios con estudiantes de secundaria y profesores en form…
2014
En resolución de problemas verbales por transferencia, la activación de problemas ya conocidos que sirvan de guía, depende de las analogías percibidas entre éstos y el problema a resolver. Se desarrollan dos estudios relacionados para analizar en qué características se basan los estudiantes para codificar problemas y detectar sus analogías, en tareas de categorización (sorting). Se utilizaron técnicas cuantitativas y cualitativas combinadas. Primero se analizó cómo los estudiantes de secundaria son influidos por diferentes variables características de problemas de ciencias. Una gran proporción de sujetos no fue capaz de percibir las analogías y diferencias adecuadas entre problemas. El segu…
Efficient Analysis of Arbitrarily Shaped Inductive Obstacles in Rectangular Waveguides Using a Surface Integral Equation Formulation
2007
In this paper we propose to use the Surface Integral Equation technique for the analysis of arbitrarily shaped Hplane obstacles in rectangular waveguides, which can contain both metallic and/or dielectric objects. The Green functions are formulated using both spectral and spatial images series, whose convergence behavior has been improved through several acceleration techniques. Proceeding in this way, the convergence of the series is not attached to the employment of any particular basis or test function, thus consequently increasing the flexibility of the implemented technique. In order to test the accuracy and numerical efficiency of the proposed method, results for practical microwave c…
Design and implementation of modelling tasks using iPad's: a dual perspective
2016
[EN] This paper presents the design of two experiences to introduce modelling of physical phe-nomena through modelling tasks using iPadR's. Each of the proposals is designed with adi erent vision about modelling. In one case modelling is used as a vehicle to introduceprecise mathematical contents. While, on the other one, we intend to develop an activitythat can help student to improve their modelling competence. Our aim is to present twoproposals to introduce modelling in a ninth or tenth grade classroom
Trandix: Herramienta Proactiva para la Búsqueda Terminológica del Traductor y su Evaluación
2014
This article is the English version of “Trandix: herramienta proactiva para la búsqueda terminológica del traductor y su evaluación” by Isabel Durán Muñoz & Alejandro Fernández Sola. It was not published on the print version of MonTI for reasons of space. The online version of MonTI does not suffer from these limitations, and this is our way of promoting plurilingualism. This paper analyses current trends in the terminological field and translators’ needs regarding terminological resources. In this context, it presents the Trandix tool, a novel software application that intends to enhance efficiency in terminological searches conducted by translators. In addition to its main features, this …
Trandix: herramienta proactiva para la búsqueda terminológica del traductor y su evaluación
2014
This paper analyses current trends in the terminography field and translators’ needs regarding terminology resources. In this context, the Trandix tool is presented as a novel software application that pursues efficiency in terminological searches conducted by translators. This tool is based on Tarp’s Function Theory of Lexicography (2008a) and Spohr’s proposal concerning electronic multifunctional dictionaries (2009). A further goal of this paper is to serve as an example for future research in terminological resources aiming to meet translators’ requirements and expectations when carrying out terminology searches
Spaces of Dirichlet series
2019
This work is dedicated to the study of multiple Dirichlet series and it focuses on three main aspects: convergence, spaces of bounded multiple Dirichlet series and the composition operators of such spaces. In the first chapter we give the necessary preliminary results on regular convergence of double and multiple series and its equivalence with the definition of convergence in a restricted sense. We also recall sequences of bounded variation and we show how they are the multipliers of convergent series in the space of sequences, extending also this characterization to double and multiple regularly conergent series. In the second chapter we recall the fundamentals on the theory of bounded or…

Differential inclusions involving normal cones of nonregular sets in Hilbert spaces
2017
This thesis is dedicated to the study of differential inclusions involving normal cones of nonregular sets in Hilbert spaces. In particular, we are interested in the sweeping process and its variants. The sweeping process is a constrained differential inclusion involving normal cones which appears naturally in several applications such as elastoplasticity, electrical circuits, hysteresis, crowd motion, etc.This work is divided conceptually in three parts: Study of positively alpha-far sets, existence results for differential inclusions involving normal cones and characterizations of Lyapunov pairs for the sweeping process. In the first part (Chapter 2), we investigate the class of positivel…
Análisis de la actividad electromiográfica superficial de la musculatura facial en niños y adolescentes según variables morfológicas, parafunciones y…
2022
Se ha analizado la actividad EMGS de los músculos faciales y suprahioideos del cuello, en niños y adolescentes con distintos patrones faciales, diferente clase esquelética y distinta clase molar de Angle, mediante pruebas estáticas y dinámicas. También se ha determinado, qué hábitos disfuncionales orales son más influyentes en la actividad muscular orofacial, así como la influencia de las variables demográficas sobre la actividad muscular orofacial. Se midió la actividad electromiográfica en los músculos temporales, maseteros, orbiculares labiales (superior e inferior) y suprahioideos, de forma bilateral, tanto en reposo como durante la realización de las siguientes tareas: máxima contracci…
Funcionamiento Neuropsicológico en el Trastorno Bipolar: Estabilizadores del Humor y Benzodiacepinas
2021
Introducción El trastorno bipolar (TB) es considerado por la Organización Mundial de la Salud como uno de los problemas de salud más urgentes a nivel mundial y una de las veinte principales causas de discapacidad. Su principal característica es la alternancia de episodios maniacos y episodios depresivos con periodos de estabilidad clínica. Por otro lado, está bien establecida la presencia de disfunciones neurocognitivas en pacientes con trastorno bipolar, asociadas a factores clínicos, tales como el número de episodios afectivos y hospitalizaciones, la duración de la enfermedad, y pobre ajuste psicosocial a largo plazo. Sin embargo, el curso longitudinal del TB es muy variable, y un subgrup…
