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...

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...

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...

Approximation algorithms for two-dimensional geometric packing problems

Gálvez, Waldo ; Grandoni, Fabrizio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO013.

There are a lot of natural problems arising in real life that can be modeled as discrete optimization problems. Unfortunately many of them are believed to be hard to solve efficiently (i.e. they cannot be solved in polynomial time unless P=NP). An approximation algorithm is one of the ways to tackle these hard optimization problems. These algorithms have polynomial running time and guarantee a...

Just-in-time information retrieval and summarization for personal assistance

Bahrainian, Seyed Ali ; Crestani, Fabio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO014.

With the rapid development of means for producing user-generated data opportunities for collecting such data over a time-line and utilizing it for various human-aid applications are more than ever. Wearable and mobile data capture devices as well as many online data channels such as search engines are all examples of means of user data collection. Such user data could be utilized to model user...

Optimization of anchor nodes placement in wireless localization networks

Balac, Katarina ; Malek, Miroslaw (Dir.) ; Prevostini, Mauro (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO009.

This work focuses on optimizing node placement for time-of-flight-based wireless localization networks. Main motivation are critical safety applications. The first part of my thesis is an experimental study on in-tunnel vehicle localization. In- tunnel localization of vehicles is crucial for emergency management, especially for large trucks transporting dangerous goods such as inflammable...

A privacy-aware and secure system for human memory augmentation

Bexheti, Agon ; Langheinrich, Marc (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO011.

The ubiquity of digital sensors embedded in today's mobile and wearable devices (e.g., smartphones, wearable cameras, wristbands) has made technology more intertwined with our life. Among many other things, this allows us to seamlessly log our daily experiences in increasing numbers and quality, a process known as ``lifelogging''. This practice produces a great amount of pictures and videos...
