3D printing of aluminum alloys under different extrusion techniques
(English) This doctoral research evaluated the feasibility of using various aluminum-based feedstocks in additive manufacturing (AM) to develop cost-effective and environmentally friendly alternatives to traditional metal ...
Reduced order models and machine learning techniques for digital twin applications
(English) This thesis advances intrusive projection-based reduced order modeling (PROM) as a scalable, physics-consistent foundation for real-time digital twins in industrial applications. By integrating high-fidelity ...
Polyhydroxyalkanoates (PHAs): processing, property modulation, and biomedical applications
(English) This doctoral thesis presents a comprehensive study on the structure-property relationships, processing behavior, and functional performance of polyhydroxyalkanoates (PHAs), with the aim of enhancing their ...
The DCT as the basis for nonlinear signal processing and task-oriented communications
(English) This dissertation addresses two fundamental and increasingly connected challenges in modern information processing: nonlinear learning and task-oriented communications. Both fields require compact, interpretable ...
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, ...
