Wave Energy Converter for Drifter Applications (WECDA)
No full textThe document is a summary of the activities carried out by the Brno University of Technology (BUT) at the EMSO Regional Facility, OBSEA, under the EMSO ERIC Physical Access Programme. The project investigated innovative, environmentally responsible alternatives to enhance the autonomy and sustainability of oceanographic drifters. By validating a new kinetic energy harvesting technology in real marine conditions, the work contributes to the development of next-generation, low-impact observation platforms.
Access to the EMSO-OBSEA cabled observatory, operated by the UPC, enabled a full evaluation of the device—from controlled laboratory characterisation to short-duration sea deployments and a dedicated long-term test. During field trials, the wave energy converter demonstrated stable and continuous energy harvesting, providing sufficient power to support low-duty-cycle sensing and some periodic wireless data transmission.
Dataset available: https://doi.org/10.5281/zenodo.17609900The requirements of ocean monitoring have driven the continued development of sensor platforms such as Lagrangian drifters, where autonomy remains a key design consideration. Energy harvesting (EH) has proven to be a reliable approach for extending the operational lifetime of these autonomous systems [1]. While solar panels are the most common commercial EH solution for enhancing drifter autonomy (e.g., Sofar: Spotter; Fastwave: Voyager Solar), their applicability is limited. To ensure accurate surface current tracking, drifters must minimize wind influence by remaining mostly submerged, which significantly reduces the effectiveness of solar energy harvesting. Moreover, relying on a single EH source
provides only a modest improvement in system autonomy.
In this project, we investigated the feasibility of harvesting the oscillatory motion of the drifter induced by ocean waves - a concept that has not been extensively explored to date. The work focused on understanding the dynamic interaction between the drifter and the surrounding water load, which is essential for designing an efficient wave energy converter (WEC). It was found that the captured energy can be maximized by properly designing the internal WEC with a natural frequency close to that of the drifter’s movement [2]. The aim was to achieve resonance between the WEC and the drifter’s motion in order to maximize the amplitude of the former’s moving parts and increase the harvested energy.Postprint (published version
Canfranc International Station (Huesca): from railway complex to luxury hotel
No full textThe article analyses the transformation of the Canfranc railway station into a luxury hotel. It is a
highly symbolic element in the Aragonese imaginary, as its inauguration represents the
culmination of the construction of a cross-border crossing linking Zaragoza with France. From
that moment on, Canfranc station became the most representative element of the line, which
remained open until an accident occurred in 1970. This event meant the closure of the pass, but
also the beginning of a struggle for its reopening that has lasted up to the present day.
From the 1990s to the present day, a series of projects have been carried out to reactivate the
station and its surroundings in order to turn it into a centre of economic attraction while at the
same time guaranteeing its conservation. The result of the whole process has been the
transformation of the surroundings into a railway garden and the refunctionalisation of the station
to convert it into a luxury hotel, in a process in which the railway complex has lost its overall
interpretation and the station has undergone a process of comprehensive remodelling that has
led to the loss of its historical values.El articulo analiza la transformación de la estación de ferrocarril de Canfranc en hotel de gran lujo. Se trata de un elemento con una gran carga simbólica en el imaginario aragonés ya que su inauguración supone la culminación de la construcción de un paso transfronterizo que une Zaragoza con Francia. La estación de Canfranc se convierte desde ese momento en el elemento más representativo de la línea que se mantiene abierta hasta un accidente acaecido en el año 1970. Este suceso supone el cierre del paso, pero también el inicio de una lucha por su reapertura que llega hasta nuestros días.
Desde los años noventa del siglo XX hasta el momento actual se han sucedido una serie de proyectos que tienen como finalidad reactivar la estación y su entorno para convertirla en un polo de atracción económica al mismo tiempo que garantizar su conservación. El resultado de todo el proceso ha supuesto la transformación del entorno en un jardín ferroviario y la refuncionalización de la estación para convertirla en un hotel de lujo, en un proceso donde el conjunto ferroviario ha perdido su lectura de conjunto y la estación se ha sometido a un proceso de remodelación integral que ha supuesto la pérdida de sus valores históricos.Peer Reviewe

Prediction methods comparison to determine LaLiga match outcomes
No full textPredicting football match outcomes is a challenging task due to the stochastic nature of football and the limited information available prior to each match. This work analyzes and compares the predictive performance of different approaches for match outcome prediction using data from La Liga. A particular focus is placed on team rating systems, including the ELO-based method employed by FIFA, as well as alternative formulations that incorporate statistical performance indicators.
In addition to rating-based approaches, statistical and machine learning models, including Poisson regression and gradient boosting methods, are evaluated. The results show that traditional rating systems provide a strong and interpretable baseline, outperforming some simple machine learning models. An enhanced rating system based on aggregated statistical performance achieves a notable improvement in predictive
accuracy, while more advanced machine learning models offer moderate additional gains at the cost of reduced interpretability.
Across all evaluated methods, predicting draws remains a significant challenge, highlighting the inherent uncertainty of football match outcomes. Overall, the findings suggest that no single approach is universally optimal and that model selection should depend on the intended application, balancing accuracy, interpretability, and robustness
Descodificant el territori : cap a una cartografia sistèmica de la ciutat contemporània
