La identidad de la diversidad funcional en la comunicación mediada por la tecnología
2017
El objeto de estudio de la investigación que a continuación se presenta gravita sobre el cambio ontológico que impone la tecnología en el ser humano. En concreto, el desarrollo de tecnologías de ayuda aplicadas a Sistemas Alternativos de Comunicación representa un interesante ejemplo de cómo dichos soportes actúan en la base de las interacciones sociales, la comunicación y, cómo esta mediación modifica la propia autoimagen e imagen social de la persona que la emplea. El presente estudio se centra en las personas con parálisis cerebral o enfermedad degenerativa neuronal y en la transformación identitaria que padecen al poderse comunicar con soportes autónomos de alta tecnología. La hipótesis…
A framework to identify primitives that represent usability within Model-Driven Development methods
2014
Context: Nowadays, there are sound methods and tools which implement the Model-Driven Development approach (MDD) satisfactorily. However, MDD approaches focus on representing and generating code that represents functionality, behaviour and persistence, putting the interaction, and more specifically the usability, in a second place. If we aim to include usability features in a system developed with a MDD tool, we need to extend manually the generated code. Objective: This paper tackles how to include functional usability features (usability recommendations strongly related to system functionality) in MDD through conceptual primitives. Method: The approach consists of studying usability guide…
A Proposal for Modelling Usability in a Holistic MDD Method
2014
Holistic methods for Model-Driven Development (MDD) aim to model all the system features in a conceptual model. This conceptual model is the input for a model compiler that can generate software systems by means of automatic transformations. However, in general, MDD methods focus on modelling the structure and functionality of systems, relegating the interaction and usability features to manual implementations at the last steps of the software development process. Some usability features are strongly related to the functionality of the system and their inclusion is not so easy. In order to facilitate the inclusion of functional usability features from the first steps of the development proc…
La información en prensa española sobre casos de violencia en parejas del mismo sexo
2016
Los medios de comunicación españoles se han hecho eco de diversos episodios de violencia en parejas del mismo sexo durante los últimos años. Dar cobertura a este fenómeno plantea interrogantes sobre cómo enfocar una realidad que se mantuvo oculta hasta hace muy poco. Metodología. El objetivo de este artículo es realizar un análisis de contenido de la información publicada en diversos diarios españoles entre 2010 y 2015. Resultados. Los resultados indican que, mientras que los periodistas han mejorado el tratamiento de la violencia de género, la información de las agresiones en parejas gays evidencia algunas características similares a las que dominaron las noticias sobre violencia contras l…
Monitoring multidimensional phenomena with a multicriteria composite performance interval approach
2021
[EN] In the last two decades, the construction of composite indicators to measure and compare multidimensional phenomena in a broad spectrum of domains has increased considerably. Different methodological approaches are used to summarise huge datasets of information in a single figure. This paper proposes a new approach that consists in computing a multicriteria composite performance interval based on different aggregation rules. The suggested approach provides an additional layer of information as the performance interval displays a lower bound from a non-compensability perspective, and an upper bound allowing for full-compensability. The outstanding features of this proposal are: 1) a dis…
Tamaño del distrito y voto estratégico en España
2004
En este estudio se analizan los efectos psicológicos del sistema electoral, prestándose atención a la influencia del tamaño o magnitud del distrito electoral en la utilización estratégica del voto en las elecciones del Congreso de los Diputados. Para medir la incidencia del voto estratégico en el comportamiento de los votantes españoles entre 1982 y 2000 se aplican los diversos enfoques propuestos para estudiar este fenómeno. Los resultados permiten afirmar que la variable institucional constituida por el sistema electoral ?el tamaño o la dimensión del distrito, o sea, la diferencia entre distritos grandes y pequeños? influye en el comportamiento de los electores.
Asynchronous sensor fusion of GPS, IMU and CAN-based odometry for heavy-duty vehicles
2021
[EN] In heavy-duty vehicles, multiple signals are available to estimate the vehicle's kinematics, such as Inertial Measurement Unit (IMU), Global Positioning System (GPS) and linear and angular speed readings from wheel tachometers on the internal Controller Area Network (CAN). These signals have different noise variance, bandwidth and sampling rate (being the latter, possibly, irregular). In this paper we present a non-linear sensor fusion algorithm allowing asynchronous sampling and non-causal smoothing. It is applied to achieve accuracy improvements when incorporating odometry measurements from CAN bus to standard GPS+IMU kinematic estimation, as well as the robustness against missing da…
Remote interspecies interactions: Improving humans and animals wellbeing through mobile playful spaces
2019
[EN] Play is an essential activity for both humans and animals as it provides stimulation and favors cognitive, physical and social development. This paper proposes a novel pervasive playful environment that allows hospitalized children to participate in remote interspecies play with dogs in a dog daycare facility, while it also allows the dogs to play by themselves with the pervasive system. The aim of this playful interactive space is to help improving both children¿s and animal¿s wellbeing and their relationships by means of technologically mediated play, while creating a solid knowledge base to define the future of pervasive interactive environments for animals.
A framework for modelling the biomechanical behaviour of the human liver during breathing in real time using machine learning
2017
Progress in biomechanical modelling of human soft tissue is the basis for the development of new clinical applications capable of improving the diagnosis and treatment of some diseases (e.g. cancer), as well as the surgical planning and guidance of some interventions. The finite element method (FEM) is one of the most popular techniques used to predict the deformation of the human soft tissue due to its high accuracy. However, FEM has an associated high computational cost, which makes it difficult its integration in real-time computer-aided surgery systems. An alternative for simulating the mechanical behaviour of human organs in real time comes from the use of machine learning (ML) techniq…
Probabilistic Self-Localization and Mapping - An Asynchronous Multirate Approach
2008
[EN] In this paper, we present a set of robust and efficient algorithms with O(N) cost for the solution of the Simultaneous Localization And Mapping (SLAM) problem of a mobile robot. First, we introduce a novel object detection method, which is mainly based on multiple line fitting method for landmark detection with regular constrained angles. Second, a line-based pose estimation method is proposed, based on LeastSquares (LS). This method performs the matching of lines, providing the global pose estimation under assumption of known Data-Association. Finally, we extend the FastSLAM (FActored Solution To SLAM) algorithm for mobile robot self-localisation and mapping by considering the asynchr…
