However, diagnostic methodologies for analog circuits are markedly less developed than those for their digital counterparts, primarily due to the inherent difficulty of detecting soft faults within analog environments. One particularly challenging category of faults involves simultaneous degradations across multiple components that do not result in a hard failure of the circuit. Indeed, there is a notable lack of studies addressing the detection of simultaneous soft faults in analog circuits. This study proposes a method for identifying this type of soft fault occurrence in analog circuits by combining Machine Learning (ML) techniques, specifically Random Forests and Artificial Neural Networks, with an Evolutionary Algorithm (EA) based on Particle Swarm Optimization (PSO). The proposed approach is validated on a second-order Sallen-Key band-pass filter, a circuit in which soft fault classification is particularly challenging. Furthermore, the study highlights the performance improvements achieved through the proposed combined method in detecting and classifying simultaneous soft faults. This study demonstrates that an iterative process combining ML and EA techniques enables accurate fault prediction in electronic circuits. Moreover, the integration of these strategies can enhance the performance of classification problems that are traditionally addressed using either ML or EA in isolation. The effectiveness of the proposed method is evaluated using several statistical metrics, including the Matthews Correlation Coefficient (MCC), F1-score, and others. 2026-03-01T00:00:00Z https://hdl.handle.net/10259/11526 Tensiones y soluciones en la relación propiedad intelectual-investigación abierta Román Pérez, Raquel de En un momento en que la Unión Europea avanza hacia una Ley del Espacio Europeo de Investigación, FESABID publica un informe que examina las tensiones entre la legislación española de propiedad intelectual y el paradigma de la ciencia abierta, y propone rutas de reforma para resolverlas. El documento, elaborado por Raquel de Román —profesora titular de Derecho civil de la Universidad de Burgos e investigadora principal del proyecto estatal “Propiedad intelectual, datos e inteligencia artificial en entornos digitales: propuestas de reforma” —, analiza las fricciones entre el marco jurídico español, los preceptos del paradigma de ciencia abierta y el compromiso, en materia de política científica nacional, para la implantación de este modelo en España. 2026-01-01T00:00:00Z https://hdl.handle.net/10259/11524 Doing Gender Online: Memetic Performances and the Digital Construction of Femininity González Calvo, Gustavo; Ospina-Betancurt, Jonathan; Hortigüela Alcalá, David This study explores how femininity and the female body are socially and culturally constructed within digital contexts, focusing on memes as sites of gendered meaning-making. Grounded in West and Zimmerman’s (Gend Soc 1(2):125–151, 1987. https://doi.org/10.1177/0891243287001002002) doing gender framework and informed by feminist theories of performativity (Butler in Gender trouble: feminism and the subversion of identity, Routledge, 1990) and digital embodiment, the research examines how women negotiate, reproduce, and resist normative ideals of beauty and bodily worth. Using a socio-narratological and visual methodology, twenty-one women enrolled in a Master’s program in Feminist Studies created or selected memes to represent their experiences with body image, media influence, and social expectations. The narrative and visual analyses revealed four interconnected themes: (1) the persistent pressure to be and to feel thin; (2) the regulatory role of mass media and social networks; (3) the transformative potential of self-acceptance and feminist consciousness; and (4) the impact of gendered social differences on bodily perception. Findings show that women continually do and undo gender through digital practices that reflect both subjection to and resistance against patriarchal norms. Memes functioned as ironic and critical spaces for re-signifying femininity, demonstrating the potential of digital humor to foster feminist awareness and collective empowerment. The study contributes to contemporary debates on gender performativity, self-objectification, and digital feminist culture by situating doing gender within the visual logic of online communication. 2026-03-01T00:00:00Z https://hdl.handle.net/10259/11523 Proposiciones de los interesados y simplificación de las cargas documentales Medina Arnáiz, Teresa La tradicional preocupación que suscita la elección del contratista por parte de una entidad del sector público ha supuesto el establecimiento, por parte de la normativa contractual, de una serie de cautelas en base a los intereses en juego. Estas cautelas se dirigen, principalmente, a la exigencia del cumplimento previo de ciertos requisitos de capacidad y solvencia a las personas naturales o jurídicas que quieren contratar con el sector público. 2024-01-01T00:00:00Z
