Asset prices and demand shocks

Barbon, Andrea ; Franzoni, Francesco (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO002.

My dissertation consists of three chapters, each of which focuses on a different area of research in asset pricing. The first chapter deals with the informational role of brokerage firms during fire sales in the equity market. The second chapter exploits the ETF program by the bank of Japan as a quasi-natural experiment to measure the slope of the equity demand curve. The last chapter presents...

Distributed systems and trusted execution environments : trade-offs and challenges

Pereira Pires, Rafael ; Felber, Pascal (Dir.) ; Pasin, Marcelo (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Security and privacy concerns in computer systems have grown in importance with the ubiquity of connected devices. Additionally, cloud computing boosts such distress as private data is stored and processed in multi-tenant infrastructure providers. In recent years, trusted execution environments (TEEs) have caught the attention of scientific and industry communities as they became largely...

Physics and information : what is the role of information in physics?

Erker, Paul ; Wolf, Stefan ; Winter, Andreas ; Huber, Marcus (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO016.

More than a century ago, physicists around the world were collectively developing a theory to describe the newly discovered strange behaviours of some physical systems. This marks the birth of quantum theory. Few decades later, the groundbreaking idea to separate information from its physical carrier led to the establishment of information theory. These, initially independent theories, merged...

Vuk, Martina ; Collaud, Thierry (Dir.)

Thèse de doctorat : Université de Fribourg, 2019.

Université de Fribourg

Environnement personnel d’apprentissage et autonomie de l’apprenant

Felder, Joris ; Charlier, Bernadette (Dir.)

Thèse de doctorat : Université de Fribourg, 2019.

Pour faire face à la problématique de l’autonomie de l’individu confronté à des objets de formation en évolution et à des outils constamment nouveaux, cette thèse cumulative développe une approche par le concept d’environnement personnel d’apprentissage (EPA). Elle situe le concept d’EPA en relation avec l’autonomie de l’apprenant, puis propose une réflexion...

Compiler analysis for hardware/software co-design and optimization : an automation framework towards more efficient Heterogeneous Computing

Zacharopoulos, Georgios ; Pozzi, Laura (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO001.

Performance increase, in terms of faster execution and energy efficiency, is a never-ending research domain and does not come for free. The breakdown of Dennard scaling, along with the seemingly inevitable end of Moore’s law economic aspect, present a new challenge to computer architects striving to achieve better performance in modern computer systems. Heterogeneous computing emerges as one...

Bayesian mixtures for large scale inference

Denti, Francesco ; Mira, Antonietta (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO001.

Bayesian mixture models are ubiquitous in statistics due to their simplicity and flexibility and can be easily employed in a wide variety of contexts. In this dissertation, we aim at providing a few contributions to current Bayesian data analysis methods, often motivated by research questions from biological applications. In particular, we focus on the development of novel Bayesian mixture...
