Blockchains in the real world: an interdisciplinary perspective on enchancing security and adoption 

Ramos, Simona (Date of defense: 2024-03-18)

This thesis investigates the complex nature of the blockchain ecosystem, where technology, law, and economics intersect across layers and applications. By offering an interdisciplinary perspective on blockchains, we seek ...

Characterization of left atrial hemodynamics with 4D flow magnetic resonance imaging, in-silico models and deep learning 

Morales Ferez, Xabier (Date of defense: 2024-04-26)

Although the left ventricle has traditionally held the spotlight as the primary determinant of cardiovascular disease prognosis, the characterization of left atrial hemodynamics is increasingly being recognized as a ...

Large scale off-policy and offline learning 

Gabbianelli, Germano (Date of defense: 2024-03-07)

Reinforcement Learning (RL), a subfield of machine learning and artifical intelligence, is a learning paradigm where an artificial agent learns to reach a predefined goal by trying to maximize a reward signal while ...

Prediction of mental health crises based on electronic health records: probabilistic and machine learning models for clinical applications 

Garriga Calleja, Roger (Date of defense: 2024-02-29)

Toward a new model of borderline personality disorder: a psychophysiological approach on the link between emotional and behavioural dysregulation 

Galli, Marco (Date of defense: 2022-05-20)

Borderline personality disorder (BPD) is one of the most studied personality disorders, given its prevalence and the severity of its symptoms. In the last years, several models of the disorder were presented, however, no ...

The role of conflict in perception: case studies in binocular rivalry, cinema and flavour 

Drew, Alice (Date of defense: 2024-02-01)

Our everyday perception of the world is remarkably unambiguous, considering that it stems from a multitude of ambiguous sensory signals. This feat is believed to be achieved by a set of perceptual and cognitive mechanisms ...
