The Architectural Graphic Representation in the Creation of New Degrowth Utopias
No full text[EN] Climatological studies have begun to confirm that Climate Change is already a reality. The discourse related to this threat have been rapidly evolving over the last decades, and that "fight" against Climate Change has turned into an effort to make our buildings more resilient to these changes. The notion that we are running out of time is spreading as quickly as the most concerning climatic data is being confirmed. Meanwhile, the depletion of natural resources and the urgency to maintain the current pace of economic growth press society to find substitutes for fossil fuels that have underpinned our economic system. In response to this situation, a portion of our profession has understood that, since buildings consume a significant portion of the energy produced, it is essential to participate in the creation of an alternative model that focuses on the relationship between human beings and the environment and on how we manage natural resources. Within this context, concerns about the habitability of a planet facing Climate Change, with an exponential increase in population and a decrease in available resources, have led fear and dystopian predictions to absorb a significant part of societal projections about the future. Faced with these forecasts, the creation of utopian future models can become a refuge for society and, above all, a tool to initiate transitions towards more responsible models that respond to the needs and conditions of the future. Visual representation becomes crucial here as it helps society project a different future, to raise awareness and consciousness. Throughout this paper, we will analyze how architecture has represented futuristic utopias over the past decades to delve into the need to represent new utopias based on a model of degrowth that is already spreading in the scientific and academic sphere, but also in the social and cultural sphere.Rosaleny-Gamón, Marcel·Lí;Rosaleny-Gamón, Carles (2026).

Species-specific responses of fish sperm to thermal incubation and activation during short-term storage
No full text[EN] Although short-term storage of diluted sperm at 0-2 degrees C with extenders has been shown to effectively preserve sperm quality, its broad applicability across fish species with different thermal preferences-and the ability of stored sperm to respond to elevated incubation or activation temperatures-remains insufficiently understood. To investigate this further, sperm samples from six species: zebrafish, common carp, European eel, gilthead seabream, sterlet and rainbow trout, were accordingly diluted with immobilising solutions and stored at 0-2 degrees C under aerobic conditions for 1 to 28 days depending on the species. The effect of the following incubation and activation at low (4 degrees C) and relatively high temperatures (natural species-specific spawning temperature) on various spermatozoa motility parameters during the storage was estimated. During sperm storage, sperm motility and velocity declined when activated at the species-specific spawning temperature. Nevertheless, incubation and activation at higher temperatures were associated with improved motility parameters in several species. Significant variations were observed between different species in spermatozoa motility (MOT) and velocity (VCL and VSL) during storage, particularly in response to low-or high-temperature incubation and activation. PCA of stored spermatozoa revealed distinct clustering of motility parameters in zebrafish, common carp, and sterlet, indicating clear thermal response patterns. In contrast, European eel and gilthead seabream exhibited no such clustering, reflecting interspecific variability in thermal sensitivity. GLMM analysis revealed that sperm motility parameters were generally affected, albeit to varying degrees, by thermal conditions during incubation and activation. Further validation using an XGBoost model revealed that storage duration, incubation, and activation temperatures markedly impacted sperm motility in thermophilic and mesophilic fish species (zebrafish, common carp, and European eel) compared to the other species. These results underscore the broad applicability and effectiveness of chilled sperm storage at 0-2 degrees C for preserving sperm quality across diverse fish species under variable thermal incubation and activation conditions.This study was partly funded by the Ministry of Education, Youth and Sports of the Czech Republic with the support of VVI CENAKVA Research Infrastructure (ID 90238, MEYS CR, 2023-2026), by the Grant Agency of the University of South Bohemia in Ceske Budejovice (107/2022/Z) and by the Czech Science Foundation (23-06426S).

Avaluació comparativa de mètriques de localitat: anàlisi de la precisió en la representació de la localitat temporal i espacial de patrons d'accés a la memòria
Full text link[EN] Memory is a critical and high-demand resource in modern computing systems, the design and management of which are crucial to performance. The growing gap between processor and memory access speeds (and bandwidth) makes optimising data access a challenging yet increasingly important task. In this context, locality of reference the tendency of a program to access a subset of memory addresses repeatedly and within a short period has become a foundational concept in the areas of Computer Science and Computer
Architecture. It is used widely both within hardware and software design and optimisation, from operating systems and caches, to web browsers and human-computer interaction.
However, there is no clear consensus on how to quantify locality that is, how to assign a value to it and on what grounds. Despite the existence of numerous proposed metrics to quantify temporal and spatial locality in the literature, there is no universal agreement on their use or precision. This bachelor s thesis addresses that gap by providing a comparative study of three locality metrics. Said metrics are evaluated against a series of synthetic traces, designed to exhibit controlled locality properties. The study then assesses how well each score aligns with the intuitive notions of temporal and spatial locality.
The results reveal that the considered metrics can produce different scores for the same memory access patterns, reflecting their divergent definitions of locality. Stride-based metrics effectively capture not only spatial locality but also distance, while block-based metrics are more sensitive to the clustering of addresses in particular block-sized regions. These findings demonstrate that a metric s utility is context-dependent, and a universal framework is yet to be achieved.[ES] En los sistemas informáticos modernos, el diseño y la gestión de la memoria disponible son fundamentales para su rendimiento. La disparidad creciente entre la velocidad de los procesadores y la de la memoria secundaria hace cada vez más necesaria la optimización del acceso a los datos. En este contexto, la localidad de referencia la tendencia de un programa a acceder sucesivamente, y durante un periodo acotado, un conjunto reducido de direcciones de memoria se ha consolidado como un concepto clave en la informática y la arquitectura de computadores.
Aun así, no existe un consenso claro sobre cómo cuantificar dicha localidad es decir, cómo asignar un valor y con qué rigor. Pese a que existen numerosas propuestas de métricas para cuantificar la localidad temporal y espacial, no hay un acuerdo universal acerca de su precisión, ni del aspecto de localidad que representan realmente. Este trabajo final de grado propone un estudio comparativo de tres métricas de localidad, basadas en conceptos conocidos como stride y reuse distance. Evaluando estas métricas a través de patrones de acceso sintéticos, diseñados con características específicas de localidad temporal y espacial, esta tesis estudia cómo se ajustan los valores producidos a las definiciones intuitivas de localidad.
Los resultados muestran que las métricas consideradas pueden producir valores distintos incluso para los mismos patrones de acceso, reflejando la influencia de las divergentes definiciones de localidad que poseen. Métricas basadas en el stride capturan de forma eficaz tanto la localidad espacial como la distancia física, mientras que métricas basadas en el tamaño de bloque son sensibles a la proximidad de las direcciones en una región de memoria. Consecuentemente, la utilidad de cada métrica depende del contexto y aún queda trabajo para conseguir un marco universal de localidad.[CA] El disseny i la gestió de la memòria disponible són aspectes fonamentals per

específiques de localitat temporal i espacial, aquesta tesi estudia com
s’amotllen els valors produïts amb les definicions intuitives de la localitat.
Els resultats mostren que les mètriques considerades poden produïr valors
divergents per als mateixos patrons d’accés, reflectint la influència de les
diferents definicions de localitat. Mètriques basades en el stride capturen
eficaçment tant la localitat espacial com la distància física, mentres que
mètriques basades en la grandària de bloc són sensibles a la proximitat de
les adreces en una regió de memòria. Per tant, la utilitat de cada mètrica depèn
del context i encara cal assolir un marc universal de localitat.[SV] Minne är en kritisk och efterfrågad resurs i moderna datorsystem, vars
utformning och hantering är avgörande för prestandan. Den växande klyftan

Creació de zones de so mitjançant aprenentatge automàtic
Full text link[ES] Las zonas de sonido personalizadas (PSZ) representan una aplicación especializada de la síntesis de campo sonoro (SFS), la disciplina más amplia del procesamiento de señales que se ocupa de recrear los campos de presión deseados utilizando conjuntos de altavoces. La creación de PSZ amplía este problema al reto específico de generar múltiples regiones acústicas independientes dentro de un entorno determinado.
Lo más habitual es reproducir un campo sonoro deseado en una zona brillante, mientras se atenúa la energía potencial acústica en una zona oscura definida. Los métodos clásicos basados en la optimización, como la igualación de presión (PM) y el control del contraste acústico (ACC), son eficaces, pero adolecen de una escasa adaptabilidad, ya que su rendimiento se degrada incluso con pequeños cambios en el entorno acústico. Las investigaciones recientes se han orientado hacia enfoques basados en datos, en los que las redes neuronales profundas (DNN) entrenadas con respuestas impulsivas de sala (RIR) simuladas demuestran una mayor robustez y generalización. Sin embargo, la escasez de conjuntos de datos RIR del mundo real disponibles públicamente sigue siendo un obstáculo importante para validar estos modelos más allá de las simulaciones.
Esto motiva nuestro trabajo, ya que investigamos un enfoque de red neuronal de autoencoder convolucional (CAE) para abordar estos retos. Para demostrar su rendimiento, primero comparamos el rendimiento del modelo CAE entrenado con datos simulados con el método clásico de optimización de mínimos cuadrados PM. También discutimos la capacidad del enfoque para generalizar a configuraciones de zonas no vistas, junto con una comparación de las diferentes funciones de pérdida utilizadas para el entrenamiento de la red. Durante los experimentos, evaluamos principalmente la precisión de reproducción y el contraste acústico (AC) de cada modelo, y comunicamos los resultados. Los resultados muestran que, aunque el aprendizaje profundo puede competir con métodos analíticos como el PM, en condiciones controladas, la solidez del enfoque sigue siendo cuestionable y requiere más experimentación. En este estudio, establecemos un marco para la simulación de datos y una arquitectura de modelo CAE que sienta las bases para futuros trabajos.[EN] Personal sound zones (PSZ) represent a specialized application of sound field synthesis (SFS), the broader signal processing discipline concerned with recreating desired pressure fields using arrays of loudspeakers. PSZ creation extends this problem to the specific challenge of generating multiple independent acoustic regions within a certain environment.
Most commonly, it involves reproducing a desired sound field in a bright zone, while attenuating the acoustic potential energy in a defined dark zone. Classical optimization-based methods, such as Pressure Matching (PM) and Acoustic Contrast Control (ACC), are effective but suffer from poor adaptability, as their performance degrades even with small changes in the acoustic environment. Recent research has shifted to data-driven approaches, where deep neural networks (DNNs) trained on simulated room impulse responses (RIRs) demonstrate improved robustness and generalization. However, the scarcity of publicly available real-world RIR datasets remains a major obstacle for validating these models beyond simulations.
This motivates our work as we investigate a convolutional autoencoder (CAE) neural network approach to address these challenges. To demonstrate its performance, we first compare the performance of the CAE model trained on simulated data with the classical PM least-square optimization method. We also discuss the approach s ability to generalize to unseen zone configurations, alongside a comparison of different loss functions used for the training of the net. During the experiments, we most importantly assess reproduction accuracy, acoustic contrast (AC) for each model, and report the findings. The results show that although deep learning can compete with analytical methods such as PM, under controlled conditions, the robustness of the approach remains questionable and needs further experimentation. In this study, we establish a framework for data simulation and a CAE model architecture that lays the groundwork for future work.Arzumanyan, H. (2025).

Before-after study of pavement roughness impact on vehicle fuel consumption and emissions
No full text[EN] This study evaluates the impact of pavement rehabilitation on vehicle fuel consumption and CO2 emissions along the M¿50 motorway in Madrid (Spain) using a before-and-after approach based on connected vehicle data. The methodology integrates fleet composition analysis, filtering for free-flow conditions, segmentation into homogeneous sections, and the definition of a representative ¿design vehicle¿ to isolate the effect of improved surface condition. Complementary statistical tests and disaggregated analyses by vehicle type and road grade confirm that an average 27% reduction in pavement roughness led to approximately 10% decreases in both fuel consumption and CO2 emissions per vehicle, with greater savings on uphill segments. When extrapolated to actual traffic volumes, the rehabilitated sections are estimated to save over 5.5 million litres of fuel and 15,000 tonnes of CO2 annually in one travel direction. These findings highlight pavement maintenance as an effective strategy for improving transport energy efficiency and contributing to road transport decarbonisation goals.Llopis-Castelló, David;Arce-Blanco, C.;Valdecantos-Álvarez, JC.

Investigating innovative methodologies in architectural education: Bridging theory and design in housing typology
Full text link[EN] This article seeks to investigate the ways in which architectural education is responsible for shaping visionary professionals. More specifically, it interrogates the ways in which architectural education can include both the contemporary discourse on socially open, inclusive environments and at the same time the diverse - in terms of the user experience and personal experiences- ideas of “home”. Every architecture student enters their education process, carrying cognitive experience, images, feelings and atmospheres of a specific “home” environment. Located in urban or rural areas, multi-storey or one-storey, the variations can be innumerable. The transformation of the strictly cognitive-driven user, to an architect who develops their projects scoping in the creation of spaces that elevate the human experience and respect the identity of the users, on the most common typology of architectural projects – the house, is the main research question of this article. How can experiential learning techniques further promote this process? The article aims at interrogating innovating ways of architectural education where theoretical and conceptual frameworks could nourish the design thinking process and encourage an interdisciplinary approach. The research on design paradigms, spatial theories and sociocultural contexts could expand the design methodological approaches in the studio projects.Furthermore, integrating sustainable design principles and strategies within a context of social responsibility as well could promote social equity through design.Connecting theory and critical thinking skills with the design process, within a systemic approach of housing typology, could address in an innovative way contemporary challenges in architectural education.Nikoloutsou, C.;Apostolou, M.;Siapati, G.

Modelatge dinàmic i disseny del control del sistema de transferència de combustible per a l'ajust del centre de gravetat en aeronaus supersòniques
No full text[EN] This Bachelor’s Thesis addresses the automatic management of the center of gravity (CG) in supersonic aircraft through fuel redistribution. Supersonic configurations experience a pronounced aft shift of the aerodynamic center as the Mach number increases, which reduces static stability margins and increases trim drag. As a result, keeping the CG within a narrow range becomes essential to ensure longitudinal stability and preserve cruise efficiency.
To study this problem, a simplified yet dynamically representative model of the fuel system is developed, obtained by reducing the Concorde’s original tank architecture to an equivalent reduced-order system. This modelling approach preserves the key physical mechanisms that govern CG evolution and allows efficient simulations to be performed in Simulink.
An initial control strategy based on decoupling is explored, but it proves insufficient due to the strong interaction between transfer flows and the limited achievable CG range. Consequently, an optimized controller is developed using a Genetic Algorithm, which tunes its gains under operational constraints and realistic fuel-consumption disturbances. The final design is further evaluated under measurement noise and more realistic operating scenarios, demonstrating robust and accurate CG tracking and a clear performance improvement over the decoupling-based approach.
The results confirm the feasibility of automatic CG control through fuel transfer and establish a general methodology applicable to future supersonic transport concepts.[ES] Este Trabajo de Fin de Grado aborda la gestión automática del centro de gravedad (CG) en aeronaves supersónicas mediante la redistribución de combustible. Las configuraciones supersónicas experimentan un desplazamiento pronunciado hacia atrás del centro aerodinámico al aumentar el número de Mach, lo que reduce los márgenes de estabilidad estática y aumenta el arrastre de trimado. Como resultado, mantener el CG dentro de un rango estrecho se vuelve esencial para garantizar la estabilidad longitudinal y preservar la eficiencia en crucero.
Para estudiar este problema, se desarrolla un modelo simplificado, pero dinámicamente representativo del sistema de combustible, obtenido mediante la reducción de la arquitectura original de tanques del Concorde a un sistema equivalente de orden reducido. Este enfoque de modelización preserva los mecanismos físicos clave que gobiernan la evolución del CG y permite realizar simulaciones eficientes en Simulink.
Se explora una estrategia de control inicial basada en el desacoplo, pero resulta insuficiente debido a la fuerte interacción entre los caudales de transferencia y el rango de centro de gravedad alcanzable. En consecuencia, se desarrolla un controlador optimizado mediante un Algoritmo Genético, encargado de ajustar sus ganancias bajo restricciones operativas y perturbaciones realistas en el consumo de combustible. El diseño final se evalúa además bajo ruido de medida y escenarios de operación más realistas, demostrando un seguimiento del centro de gravedad robusto y preciso, así como una mejora clara del rendimiento respecto al enfoque basado en desacoplo.
Los resultados confirman la viabilidad del control automático del CG mediante transferencia de combustible y establecen una metodología general aplicable a futuros conceptos de transporte supersónico.Gil Maciá, M.
