Human-robot interaction with pointing gestures : intuitive interaction between co-located humans and robots

Gromov, Boris ; Gambardella, Luca Maria (Dir.) ; Giusti, Alessandro (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO004.

Human-robot interaction (HRI) is an active area of research and an essential component for the effective integration of mobile robots in everyday environments. In this PhD work, we studied, designed, implemented, and experimentally validated new efficient interaction modalities between humans and robots that share the same workspace. The core of the work revolves around deictic (pointing)...

Parallel space-time multilevel methods with application to electrophysiology : theory and implementation

Benedusi, Pietro ; Krause, Rolf (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO005.

The goal of this thesis is to design and study an efficient strategy to solve possibly non-linear parabolic partial differential equations on massively parallel machines. Traditionally, when solving time-dependent problems, time stepping methods are used to advance the solution in time. These techniques are inherently sequential and therefore they introduce a bottleneck in the overall...

Secrecy in the age of transparency : an investigation into legitimations, conceptions and practices of non-disclosure

Heide, Marlen ; Villeneuve, Jean-Patrick (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019COM004.

The objective of this research is to illustrate the complexity and fluidity of the relationship between secrecy and transparency by considering the multiple rationales that serve to justify secrecy. The conceptual contribution of this thesis lies at two levels: (1) the reconceptualization of national security secrecy from realism to risk management and (2) the implications of such...

Experiential learning under ambiguity

Wahle, Thorsten ; Martignoni, Dirk (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO003.

In this dissertation I study choice contexts of learning under ambiguity. Experiential learning takes place by making choices, observing the outcomes, and altering future choices accordingly. Over time, such learning is expected to improve choices and outcomes but only when decision makers can classify outcomes as either successes or failures. This dichotomous outcome has clear behavioral...

Labour market outcomes : Careers, transitions and durations

Malfitano, Paolo ; Maggi, Rico (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO004.

This thesis contributes to labour economics by considering a wide range of factors influencing career paths, transitions to self- employment and duration in entrepreneurship. In the past literature, several studies have analysed labour market outcomes, transitions and durations. Nevertheless, there is the need of knowing more about the influence of individual and background characteristics on...

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...

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...

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...

The digital birth of an African city : the case of Douala

Pucciarelli, Marta ; Cantoni, Lorenzo (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019COM003.

This dissertation focuses on the online communication and representation of a digital city in Africa: Douala, the largest city of the Republic of Cameroon. In particular, it explores the evolution of the web-based reproduction (Couclelis, 2004) of Douala, the largest city of the Republic of Cameroon, from a chronological, spatial and representational perspective, with the purpose of...
