Shear response of dredged sand concrete elements: experimental behavior and theoretical model
(English) The Yangtze River shipping industry is becoming increasingly developed. To ensure the navigability of the Yangtze River, regular channel maintenance is required, which generates a large amount of dredged sand. ...
Development of innovative land applications for ESA's HydroGNSS mission
(English) The research presented in this paper-based dissertation focuses on the development of products for the ESA HydroGNSS mission, including the Level 2 surface inundation algorithm, the exploitation of the coherent ...
Integrating AI with multiphoton autofluorescence-based hyperspectral imaging for enhanced embryo and oocyte analysis
(English) Infertility affects one in seven couples, according to the World Health Organization, and only around 30% of the embryos from in vitro fertilization treatments successfully implant in the uterus and develop to ...
Human-on-the-loop continual learning: data, knowledge and agents for model adaptation
(English) How do we effectively adapt a Machine Learning (ML) model when real-world data changes? This seemingly straightforward question underlies one of the most persistent challenges in deploying ML systems in production ...
Evaluating the impact of corporate social responsibility on financial performance, productivity, and critical success factors in the European mining industry
(English) Responsible and ethical business practices have gained prominence, particularly through Corporate Social Responsibility (CSR). Over four decades, CSR disclosure evolved significantly, increasingly appearing in ...
Data-driven patient-specific models supporting decision making with application to atherosclerotic plaque analysis
(English) This thesis advances finite element-based tools to improve atherosclerosis analysis by addressing current computational limitations. Atherosclerosis, the leading cause of ischaemic heart attacks, imposes a ...
Radar-based techniques for continuous monitoring of soil moisture and vegetation using time series analysis
(English) Ongoing changes in climate and weather patterns have emphasized the need for improved observation and understanding of rapid land–atmosphere interactions, particularly those related to the water cycle. This thesis ...
Exploring multi-barrier approaches for impacted urban groundwater reclamation in Sant Adrià del Besòs basin
(English) This thesis aims to identify and assess the treatment of water sourced from the Sant Adrià del Besòs aquifer using various types of technologies, in accordance with the compliance of the regulations regarding its ...
Supervised and reinforcement learning for extreme adaptive optics with application to exoplanet imaging
(English) This thesis demonstrates that applying a combination of deep learning (DL) models in adaptive optics (AO), each addressing an AO error source, can significantly increase performance, providing telescopes with ...
Theoretical aspects of the interaction of free and tunneling electrons with low-dimensional photonic systems
(English) In this thesis, we provided a theoretical description of how focused electron beams interact with low-energy excitations and generate nanoscale light, which is of great interest in the field of nanophotonics. In ...
Post-earthquake functional recovery and resilience of seismically isolated hospitals and large-scale building portfolios
(English) This dissertation presents a comprehensive contribution to assessing and optimizing the functional resilience of both individual hospital buildings and urban-scale building portfolios. The research addresses ...
Coupled modelling and sustainability assessment of polymeric reinforced soil retaining structures subjected to environmental conditions
(English) The focus of this Thesis are reinforced soil structures with polymeric (or geosynthetic) reinforcement elements. These materials are known for their rate-dependent behaviour, that is, time, load, temperature, ...
Engineering zirconia surfaces with cell instructive and antibacterial properties
(English) Tetragonal zirconia polycrystals stabilized with 3 mol% yttria (3Y-TZP) has gained growing interest as an alternative to titanium for dental implants, owing to its excellent biocompatibility, high mechanical ...
Real-time data-driven safety assessment for building structures
(English) The evolution mechanism of structural performance remains a critical research topic in structural mechanics. Cracks, serving as indicators of performance deterioration, manifest physically at the meso-scale as ...
Alison & Peter Smithson, Axel Bruchhäuser and the Hexenhaus. The added value of the conglomerate ordering
(English) Between 1985 and 2002, British architects Alison and Peter Smithson transformed the Hexenhaus—a modest half-timbered building in Bad Karlshafen, Germany—into one of the late twentieth century's most remarkable ...
Consumer preferences and acceptance for sustainable food systems
(English) As consumers increasingly recognise the health, ethical, and environmental impacts of their dietary choices, a shift toward sustainable food systems is emerging. This dissertation explores consumer preferences, ...
Development of a methodology for optimizing transformers and devices with magnetic core
(English) This thesis contributes to the field of design and optimization of magnetic core devices, specifically transformers for power electronics. A calculation software has been developed for the design of transformers, ...
Cobalt-ruthenium bimetallic catalysts for dry reforming of methane
(English) The processes used nowadays for hydrogen and syngas production require more sustainable alternatives to advance in the necessary decarbonisation to fight against climate crisis. Currently, the main process is ...
Reuse of ICT devices as commons: a property rights governance model for collective access
(English) Understanding the role of property rights in managing Information and Communication Technology devices, primarily computers, is fundamental to addressing resource waste and achieving digital inclusion and ...
Novel dispersion error and grey area mitigation approaches for subsonic jet noise spectra
(English) In Computational AeroAcoustics, scientists deal with a numerical error not always considered in other disciplines: the dispersion error. This error generates that waves with different frequencies travel at different ...
