Ítem Elaboración de un portafolio electrónico para el desarrollo docente a través de una Unidad Didáctica Virtual(Universidad de Zaragoza, Servicio de Publicaciones, 2021) Romero Yesa, Susana; Aláez, Marian; García Olalla, Ana María; Segú Odriozola, MabelLa docencia de calidad es una preocupación fundamental en las universidades. La evaluación acreditativa del profesorado a través de las agencias de calidad responde a esa inquietud. En la Universidad de Deusto, esta acreditación se estructura en tres niveles: la acreditación de la planificación de la docencia, la acreditación de su puesta en práctica y la revisión y mejora desde un enfoque de colegialidad. En esta comunicación nos centramos en la segunda. El profesorado se debe presentar a una evaluación acreditativa mediante la preparación de un portafolio docente. La Unidad de Innovación Docente ofrece talleres en los que los coordinadores de los centros acompañan a los profesores en su elaboración. Además de esta formación presencial, el profesorado necesita contar con documentación de apoyo accesible y actualizada. Para dar respuesta a esta necesidad, se ha elaborado en la plataforma institucional tipo Moodle, mediante un proyecto de innovación docente, una Unidad Didáctica Virtual (UDV) de apoyo a la formación presencial. En ella se ha elaborado una plantilla y se han incluido recursos como presentaciones, vídeos, foros y ejemplos de las evidencias a presentar. Los resultados han sido muy satisfactorios en relación con el cumplimiento de los objetivos establecidos e indicadores de impacto.Ítem Actividades transversales entre materias de primer curso de grado y trabajo en equipo para aumentar la motivación del alumno(Universidad de Zaragoza, Servicio de Publicaciones, 2021) Fonseca Escudero, David ; Necchi, Silvia; Aláez, Marian ; Romero Yesa, Susana; Centeno Hernández, EfraimMotivar al alumno de primer curso de grado, no solo mejora su grado de satisfacción y su rendimiento, sino que puede prevenir el riesgo de abandono temprano de los estudios. En este sentido, para potenciar la motivación se antoja como estrategia importante trabajar las competencias específicas desde un abordaje transversal, menos específico y que permita al alumno vislumbrar las potencialidades de sus estudios y de sus relaciones entre iguales. El presente artículo muestra el resultado de dos actividades transversales realizadas en el primer curso del grado de Estudios en Arquitectura, donde el trabajo en equipo es esencial para su entrega. Los resultados han permitido identificar tanto fortalezas como debilidades de cada práctica gracias a su enfoque mixto (cuantitativo / cualitativo), lo que permitirá un rediseño de las actividades para el siguiente curso.Ítem Ocio y aprendizaje a lo largo de la vida: un binomio en positivo(REDINE (Red de Investigación e Innovación Educativa), 2020) Lázaro Fernández, Yolanda; Doistua Nebreda, JosebaÍtem Model-based outlier detection in district heating systems(Elsevier B.V., 2024) Garay Martínez, Roberto; Siddique, Muhammad Talha; López Garde, Juan ManuelData-driven methods are increasingly popular for building energy performance assessment. For these to be useful, it is required that good quality data is created through the filtering of outliers and imputation of missing information. In the field of energy use in buildings, there is a clear sensitivity of heat load to outdoor climate, which needs to be considered when identifying outliers and developing imputation methods. We propose to use a well-known changepoint model to define the sensitivity of the data to climate, further segmented by time of the week. Then we use the residuals of the model to identify outliers, where those observation with residuals substantially out of the normality expectations are identified as outliers. Then missing data is repaired by means of linear imputation techniques, considering the patterns for same times of the week in the dataset. As a result of the full process, we were able to identify 5% of outliers, which resulted in the improvement of model metrics in the range of 20% mean absolute error (MAE) and slightly better R2 values.Ítem Design of monitoring tool for decision making in buildings with solar energy generation(Elsevier B.V., 2024) García Quintanilla, José Ignacio; Macarulla, Ana María; Sainz Bedoya, Nekane Ione; Canivell Castillo, VerónicaThe work presented in this article is part of a project that focuses on the field of energy and sustainability and is aligned with the objectives of sustainable development, specifically goal seven, affordable and clean energy, and goal eleven, sustainable cities and communities. The photovoltaic solar installation for self-consumption at the Deusto University's residence hall been modelled using generation data, consumption data, meteorological data, and installation components. Although the actual installation features an anti-feeding system, the model allows to evaluate potential energy surpluses. To achieve this objective, it has been necessary to collect, transform, and thoroughly clean the data from the solar inverters, as well as store them for later representation. To process, visualize, and analyse data, the web application developed allows users to understand quickly and easily the patterns and trends related to energy consumption through various graphics, providing a clear and accessible visual presentation of the data that helps them make decisions to optimize energy consumption. In addition, an application has been developed that allows to assess whether or not removing the anti-feeding system and modifying the contract with the distribution company may be favourable.Ítem Optical and thermal modeling of a transparent BIPV system for dynamic performance in buildings(Elsevier B.V., 2024) Garay Martínez, Roberto; Siddique, Muhammad TalhaIn developed countries, the building sector accounts for up to 40% of the consumed energy. During the past centuries, fossil fuels have been the main energy source to heat, cool, or provide electric power to buildings, but with the increasing energy prices in the beginning of the 21st century, an increasing number of products and systems have been developed for the integration of renewable energy systems in the building sector. One of the most commonly used technologies involves the integration of photo-voltaic (PV) systems in the building fabric. Several technical solutions are available for this integration, although most common ones are related to PV integration in roofs. However, an increasing interest has been shown in semi-transparent PV systems for integration in windows and curtain-wall systems.Ítem Adaptability and efficiency in population management: a multi-population CMA-ES strategy for high-dimensional optimization(Elsevier B.V., 2024) Morales Castañeda, Bernardo; Rodríguez Esparza, Erick; Oliva, Diego; Navarro, Mario A.; Aranguren, Itzel; Casas Ordaz, Ángel; Beltran, Luis A.; Zapotecas Martínez, SaúlIn the context of evolutionary algorithms, having the ability to adapt to any search space within an optimization problem is an essential task. Appropriately adapting the population can lead to better solutions and more efficient use of function call resources. This article presents a renewed approach to population management inspired by modifying the well-known Covariance Matrix Adaptation Evolution Strategy (CMA-ES) algorithm. The proposed strategy aims to improve the algorithm's population adaptability to the search space and optimize function evaluations. Statistically evaluated experimental test outcomes demonstrate significantly better performance on high-dimensional problems in comparison to the original CMA-ES and seven other known evolutionary algorithms in the literature.Ítem On the improvement of generalization and stability of forward-only learning via neural polarization(IOS Press BV, 2024-10-16) Terres Escudero, Erik B.; Ser Lorente, Javier del; García Bringas, PabloForward-only learning algorithms have recently gained attention as alternatives to gradient backpropagation, replacing the backward step of this latter solver with an additional contrastive forward pass. Among these approaches, the so-called Forward-Forward Algorithm (FFA) has been shown to achieve competitive levels of performance in terms of generalization and complexity. Networks trained using FFA learn to contrastively maximize a layer-wise defined goodness score when presented with real data (denoted as positive samples) and to minimize it when processing synthetic data (corr. negative samples). However, this algorithm still faces weaknesses that negatively affect the model accuracy and training stability, primarily due to a gradient imbalance between positive and negative samples. To overcome this issue, in this work we propose a novel implementation of the FFA algorithm, denoted as Polar-FFA, which extends the original formulation by introducing a neural division (polarization) between positive and negative instances. Neurons in each of these groups aim to maximize their goodness when presented with their respective data type, thereby creating a symmetric gradient behavior. To empirically gauge the improved learning capabilities of our proposed Polar-FFA, we perform several systematic experiments using different activation and goodness functions over image classification datasets. Our results demonstrate that Polar-FFA outperforms FFA in terms of accuracy and convergence speed. Furthermore, its lower reliance on hyperparameters reduces the need for hyperparameter tuning to guarantee optimal generalization capabilities, thereby allowing for a broader range of neural network configurations.Ítem Reinterpretando una obra del Museo del Prado a través de la óptica del diseño y la fabricación digital(MusicoGuia, 2024) Fernández Gago, Paula; Martínez Rodríguez, RodrigoEste trabajo fusiona el pensamiento de diseño, el arte y el uso de la tecnología en la educación superior. El reto se centra en reinterpretar la obra “La extracción de la piedra de la locura” de El Bosco, actualizando su lenguaje al siglo XXI. Para ello se llevó a cabo un proyecto guiado por el pensamiento de diseño, que abarcó desde la investigación del catálogo del Museo hasta el fomento de la creatividad a través de la conceptualización de la propuesta, finalizando con la materialización de la misma haciendo uso de tecnologías de fabricación digital. Todo ello con el objetivo último de transmitir un mensaje crítico sobre las adicciones y las contradicciones de la sociedad actual.Ítem Análisis crítico de la protección del nómada digital: entre precariedad y privilegio digital(Laborum, 2024-10-20) Martínez Martínez, IreneÍtem Ajustes y desajustes en las prestaciones de seguridad social para con las personas trabajadoras a tiempo parcial(Laborum, 2024-10-20) Arrieta Idiakez, Francisco JavierÍtem Energy consumption monitoring in DED-LB for enhancing the process sustainability(Elsevier B.V., 2024) Urresti, Aizpea; Arrizubieta, Jon Iñaki; Loroño, Agathe; Ukar Arrien, OlatzEnergy efficiency is a highly relevant aspect in modern manufacturing processes, not only for economic reasons, but also because of the environmental impact it generates. With the aim of contributing to a more efficient and environmentally friendly manufacturing process, this research analyses the energy consumption of the Laser Directed Energy Deposition (DED-LB). First, the energy efficiency of the laser generator is characterized. In a second step, the deposition process is evaluated, which enables to categorize the process according to the amount of energy required per gram of material deposited, and the mass-deposition efficiency. For this purpose, a 3-level design of experiment (DOE) is performed in order to study the effect of the laser power, mass rate, and machine feed rate on the process efficiency. Besides, a metallographic study is also performed to ensure the metallurgical quality. Energy and material saving of 35% are obtained without influencing the clad quality.Ítem Analytical fractional reduced-order model identification method for processes with overdamped and underdamped response(Elsevier B.V., 2024) Gude, Juan José; Baraldi, Flavia B.; Oleagordia Ruiz, Ibon; García Bringas, PabloIn this paper, an analytical procedure to identify a fractional-first order plus dead time (FFOPDT) model is presented. This procedure is applied to processes with overdamped or underdamped step response, i.e., fractional order values in the range 0.5 ≤ α ≤ 2.0 can be estimated. The required process information is obtained through a simple open-loop step experiment and is based on fitting three arbitrary points (x1-x2-x3%) on the process reaction curve. Some numerical examples are proposed to show the effectiveness and applicability of this procedure for the identification of fractional-order models. The main feature of this approach is that it estimates the FFOPDT model of overdamped and underdamped processes.Ítem Participatory strategies to integrate gender+ into teaching and research(Academic Conferences and Publishing International Limited, 2024-04-18) Campanini Vilhena, Fernanda; Bencivenga, Rita; López Belloso, María; Taramasso, Angela Celeste; Leone, CinziaThis article explores the use of participatory approaches to promote gender equality in academia, focusing on initiatives implemented in two universities. First, we look at the experience of the University of Deusto (Spain) in developing a handbook to integrate a gender perspective into teaching and research practises through an equality, diversity and inclusion lens (EDI). This initiative, carried out as part of the university’s Gender Equality Plan, featured active involvement from scholars representing the faculties of Law, Psychology, Social Sciences and Humanities, Engineering, Business, and Theology, as well as the university’s Social Responsibility Unit. It serves as a valuable example of how participatory strategies can effectively engage a wide array of institutional stakeholders in change-oriented actions. Promoting increased participation fosters a sense of ownership of the process and outcomes among stakeholders and strengthens institutional recognition. Second, we analyse the introduction of a "gender+-responsive curriculum" developed at the University of Genoa (Italy), as part of the university’s Gender Equality Plan. This initiative seeks to promote inclusion across all disciplinary subjects by incorporating current research that examines subject matters through the lens EDI, where relevant. The pilot implementation was undertaken in an undergraduate course focused on hydraulic engineering and hydrology, drawing guidance from various resources, including academic publications and EU-funded project reports. This initiative highlights the practical implications and challenges associated with interventions aiming to challenge conventional teaching and research norms from an EDI perspective, particularly in STEM fields. By exploring the experiences, obstacles and solutions associated with a gender+-responsive curriculum, we broaden our understanding of academia’s potential to advance gender equality, diversity, and inclusion. In examining the two experiences, we emphasise the theoretical underpinnings that underscore the importance of participatory approaches for promoting meaningful and enduring changes in academic institutions. Additionally, we highlight the ongoing challenges associated with implementing such changes and offer initial insights into potential strategies for overcoming these obstacles. Our goal is to ensure that gender and other intersecting diversity factors are not relegated to the edges of institutional priorities, but are instead mainstreamed into wider institutional practices.Ítem Connections between a tourist destination, the digital ecosystem, and ICT actors(Springer Nature, 2024) Alzua Sorzabal, Aurkene; Herasimovich, Volha; Guereño-Omil, Basagaitz; Thiel-Ellul, DanielaThe tourism sector and tourist destinations are undergoing a digital transition in order to improve their resilience and competitiveness. The way in which tourist destinations address this digital transition differs, as some incorporate more technology in their ecosystem than others, giving rise to the emergence of different types of digital tourism networks. This study seeks to determine the different ways in which a tourist destination connects with a digital ecosystem, specifically focusing on the connections with ICT actors. It is based on the theoretical framework of tourism as an ecosystem. Using web crawling, network data have been compiled on 670 tourism actors and more than 36,000 websites to which they are connected through hyperlinks. The most frequently linked entities of the discovered digital ecosystem have been identified and classified (n = 447), distinguishing between 13 types of ICT actors. The results show how the online destination network has been incorporated into the digital ecosystem. The study reveals that the configuration of the digital ecosystem surrounding a tourist destination is characterised by the different levels of importance for the network of destination actors in which the ICT actors play a central role.Ítem A data-driven model for the analysis of energy consumption in buildings(EDP Sciences, 2024-05-07) Borgato, Nicola; Prataviera, Enrico; Bordignon, Sara; Garay Martínez, Roberto; Zarrella, AngeloData-driven models are gaining traction in Building Energy Simulation, driven by the increasing role of smart metering and control in buildings. This paper aims to enhance the knowledge in this sector by introducing a practical method to analyse heating consumption. The methodology involves the analysis of hourly total heating demand and outdoor temperature measurements to create and calibrate Energy Signature Curves. Importantly, the building Energy Signature Curve is calibrated independently for each daily hour, resulting in a subset of 24 data-driven models. After calibration, a disaggregation algorithm is proposed to distinguish space heating from domestic hot water usage. The method also evaluates the building's thermal inertia, examining the correlation between the hourly global energy consumption and the outdoor air temperature moving average. It also presents a methodology for improving the DHW heat consumption model. The methodology is applied to a case study of 51 buildings in Tartu, Estonia, with complete yearly demand measurements from the district heating operator. Thanks to the hourly calibration approach, R2 is 0.05 higher on average than the yearly Energy Signature Curve approach. The difference between estimated and measured annual energy consumption is 8% on average, demonstrating the practicality and effectiveness of the proposed method.Ítem Cross-generational perceptions on climate change: resolutive insights from youth and elder(Universidad del País Vasco = Euskal Herriko Unibertsitatea, 2024) Divasson Jaureguibarria, Asier; Quesada Granja, Carlos; Casado Mansilla, Diego; Cubillo Eguizabal, Iker; Aguayo Mendoza, Armando; Borges Hernández, Cruz E.In a world increasingly dominated by conversations about climate change, this research delves deeper, exploring the disconnect between widespread awareness and the implementation of concrete actions to mitigate global warming and adapt to the energy transition. The study investigates this gap by focusing on the concerns of two distinct demographic groups: teenagers and adults. Conceived during the Zientzia Azoka event and developed through other events and sessions, the project actively engaged over 131 participants in a series of workshops. These participants spanned various age groups: 16 individuals under the age of 18, 110 adults between 18 and 65 years old, and 5 adults over 65 years old. The workshops employed qualitative methods, presenting participants with a range of potential climate crisis scenarios encompassing environmental challenges, energy shortages, and mobility restrictions. These scenarios explored situations such as insufficient renewable energy development leading to electricity shortages, extreme weather events causing food scarcity, and disruptions to travel due to fuel shortages. Participants’ responses to these scenarios were then subjected to a process of semi-quantification, enabling a more nuanced analysis of their concerns. The analysis revealed not only a clear awareness of these impending challenges among both teenagers and adults, but also a recognition of the substantial barriers hindering proactive solutions. These barriers encompassed economic constraints, a perceived lack of general awareness about the gravity of the situation, and the ever-evolving social landscape shaped by recent global events like the COVID-19 pandemic and the war in Ukraine. However, amidst these anxieties, a glimmer of hope emerged. Participants identified a potential shift in societal behavior, possibly driven by these very crises. Thematic analysis of their responses revealed a strong emphasis on the crucial role of sufficiency in mitigating climate change. This highlights the importance of reducing consumption and waste rather than solely relying on technological advancements as the solution. Additionally, peer influence was recognized as a significant force in shaping attitudes and behaviors, suggesting a powerful avenue for promoting positive change. The political dimension of climate action also came into sharp focus. Participants demonstrated a sophisticated understanding of the complexities surrounding political processes and the challenges they present. They emphasized the need for clear and effective communication from political leaders, while acknowledging concerns about political motivations and the influence of special interest groups. This underscores the intricate relationship between politics, media, and public perception, highlighting the need for a multi-faceted approach to climate communication.Ítem V2G-QUESTS integrating vehicle-to-grid technologies for equitable and sustainable transitions in positive energy districts(Universidad del País Vasco = Euskal Herriko Unibertsitatea, 2024) Divasson Jaureguibarria, Asier; Macarulla, Ana María; García Quintanilla, José Ignacio; Borges Hernández, Cruz E.The Vehicle to Grid for Equitable Zero-Emission Transitions in positive energy districts (V2G-QUESTS) project is presented as a pioneering and crucial initiative in the context of a fair and equitable digital transition. In a world where technological development faces the challenge of mitigating environmental degradation caused by climate change, V2G-QUESTS stands out in preventing the unequal or harmful development of technologies such as Vehicle-to-Grid (V2G) in urban environments, particularly in socially disadvantaged communities, betting on social equity in the adoption of advanced technologies. The essence of V2G-QUESTS lies in its holistic approach that integrates social sciences to understand how technological innovations impact and are shaped by social, economic, and cultural structures. The project commits to ensuring that the transition to sustainable energy systems and mobility technologies is not only environmentally sustainable but also socially just and accessible to all strata of society. To discern the impact of the urban transition to this new technological model, an urban simulation environment based on Multi-Agent Systems will be developed, which will replicate social behavior at different degrees and case studies across the European territory. This approach allows an interdisciplinary analysis of the interactions and the impact of V2G technology in different social and technical spheres, enabling regional organizations and institutions to adapt to the future needs of their inhabitants. This task involves integrating into a multi-agent system a detailed model of the electrical energy system, as well as a model of daily transportation needs, a model of transportation mode selection that includes driving behavior and the interaction of drivers with V2G technologies, and a model of social impact on the various agents involved. Orchestrating all these models will allow capturing the complexity of the interactions between different agents, such as energy providers, electric vehicle users, and network operators to ensure that the simulations reflect realistic scenarios and provide valuable insights into how users can interact with the V2G system. To achieve these objectives, it is necessary to specify the main characteristics to be embodied in each scenario to be specified, considering the three urban dimensions; society, economy and technical infrastructure. The present study focuses its efforts on specifying these vital characteristics for the specification of the scenarios.Ítem El discurso del vencido por la vida: la percepción del envejecimiento y de la muerte en los Diarios de Rafael Chirbes(Fundación 26 de Diciembre, 2024) Soguero García, Francisco MiguelÍtem Trabajando conjuntamente: proyecto colaborativo entre asignaturas de inglés(Grupo de Comunicación Loyola, 2018) Gutiérrez Fernández, Nerea; Korres, Oihane
