Towards seamless integration of data and physics: machine learning workflows for subsurface flow and induced seismicity forecasting in geo-energy applications
(English) Geo-energy applications, such as geothermal energy, geologic carbon capture and storage, and underground hydrogen storage, have the potential to address anthropogenic climate change by contributing to the ...
The role of resonances in Arnold diffusion
(English) This thesis presents contributions to the areas of exponentially small splitting of separatrices and Arnold diffusion in the context of theory of perturbation in Hamiltonian systems In the first chapter que study ...
Drivers of public participation in ecological restoration: evidence from Tunisia
(English) The challenges facing the lagoon and aquifer ecosystems in North Africa highlight the critical need for sustainable restoration and management solutions. This thesis examines both the socio-economic and environmental ...
Vulnerabilidad + regeneración = población en peligro de expulsión. Aprendizajes para una regeneración urbana inclusiva
(English) This proposal is within the framework of a research project ‘Socio-spatial indicators for the improvement of building stock in vulnerable areas. Action criteria for the cases of the Metropolitan Areas of Barcelona ...
Respiratory viruses in childhood: surveillance, analysis, and modelling of their epidemiological dynamics. The case of Catalonia.
(English) This PhD thesis focused on the characterisation and understanding of the dynamics of SARS-CoV-2, influenza, and respiratory syncytial virus (RSV) in children in Catalonia over the last decade. Through a combination ...
Conceptualization, design and optimal operation of hybrid AC-DC power router grids

Talent management in Spanish SME hotel sector
(English) Hospitality has a great role in economy of Spain as the second most visited country in the world. Human resources (HRs) are the most important resources in this industry. Talented employees can be competitive ...
Exciton engineering for quantum confinement in an electrostatically defined PN-junction
(English) We investigate the physics of quantum-confined excitons in an electrostatically defined PN junction. Such a PN junction can be generated in an encapsulated monolayer MoSe2 along the patterned edge of a top-gate ...
Derivatives and risks
(English) This thesis aims to provide solutions to real world problems by the use and development of state-of-the-art quantitative finance techniques. The first part of this work tackles the challenge of digital options ...
Lessons learned from the survey of damage to school buildings by the Mw = 8.4 Illapel earthquake (Chile, September 2015)
(English) The high seismic hazard present in the Chilean territory demands that essential buildings, such as educational facilities, be designed under rigorous structural performance criteria. However, recent events such ...
Efectos barocalóricos en cristales plásticos orgánicos y ferroeléctricos
(English) Artificial refrigeration is one of the greatest technological achievements, essential in both industrial and domestic sectors for the preservation of food, medicines, and space cooling. It is expected that the ...
Development of hyperreduced order models for multiphysics numerical simulations: a noninvasive approach
(English) Reduced Order Models (ROMs) are powerful tools for accelerating numerical simulations by identifying and exploiting underlying structures in complex systems. By approximating high-dimensional problems using ...
Contextual speech recognition
(English) Although Automatic Speech Recognition (ASR) technology has achieved remarkable improvements in transcription accuracy in recent years, it still struggles to correctly transcribe certain words. In particular, ...
Instance-level recognition for image understanding
(English) Image understanding is a fundamental task in computer vision as it aims to enable machines to visually comprehend the real world. In this thesis, the task of image understanding is addressed through the combination ...
Understanding human intention for human-robot interaction
(English) This doctoral thesis delves into the concept of intention in robotics, aiming to establish a comprehensive and practical definition while exploring its technical and social implications. The research begins by ...
Finite element computational modeling of flexoelectricity and flexo-photovoltaics
(English) This PhD focuses on the numerical modeling of flexoelectricity and flexo-photovoltaics, both at infinitesimal and finite deformations, using standard C0 Finite Element (FE) approximations. On one side, an ...
Oscillatory motions, parabolic orbits and collision orbits in the planar circular restricted three-body problem
(English) The planar circular restricted three body problem (PCRTBP) models the motion of a massless body under the attraction of other two bodies, the primaries, which describe circular orbits around their common center ...
Contributions to the assessment of indoor air quality, thermal comfort and ventilation in educational buildings
(English) Indoor air quality and thermal comfort in educational buildings have significant impacts on students’ health, well-being, productivity, and learning performance. Schools, where students spend most of their day, ...
Probing structural coherence across a light-induced double phase transition
(English) Strongly-correlated materials have emerged as one of the most active areas of research in Condensed Matter Physics. Interests in these materials arise mainly from the pliability of their properties, offering the ...
