Social dimensions of public large-scale wi-fi networks : the cases of a municipal and a community wireless network

Picco-Schwendener, Anna ; Cantoni, Lorenzo (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018COM011.

Wireless networks play an increasingly important role in today’s mobile and interconnected society. People use mobile devices such as smartphones, tablets or portable game consoles on a regular basis to interact, retrieve and share information, and to orient and entertain themselves. However, in order to be fully performant these devices need to be connected to the Internet. Thanks to very...

Derivative securities in risk management and asset pricing

Legnazzi, Chiara ; Barone-Adesi, Giovanni (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO009.

The high informational content and the ease of accessibility are among the most attractive features which make derivative securities particularly useful in financial applications. With a special focus on risk management and asset pricing, I present several methodologies which involve the use of option and futures data in the estimation process. This doctoral thesis consists of three chapters....

ASQ : active learning with interactive web presentations and classroom analytics

Triglianos, Vasileios ; Pautasso, Cesare (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO013.

Today it is commonly accepted that the effectiveness of instructional technology, measured as improvement over the learning outcomes of students, is highly correlated with the learning environment, the applied pedagogies and the goals of the participants of the learning process. The often applied passive lecture model and the undirected use of modern technology such as student laptops and...

Time aware location recommendations in location based social networks

Mudda, Steven ; Giordano, Silvia (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO012.

Smartphones have fundamentally changed how people make choices about the products and services they consume and the way they interact with each other. The spread and extensive usage of mobile applications has led to the rise of Location-based Social Network (LBSN) services like Foursquare, Yelp etc, that aim to aim to provide new and novel places of interest to people based on their interests...

Path planning for mobile robots in the real world : handling multiple objectives, hierarchical structures and partial information

Guzzi, Jérôme ; Gambardella, Luca Maria (Dir.) ; Giusti, Alessandro (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO010.

Autonomous robots in real-world environments face a number of challenges even to accomplish apparently simple tasks like moving to a given location. We present four realistic scenarios in which robot navigation takes into account partial information, hierarchical structures, and multiple objectives. We start by discussing navigation in indoor environments shared with people, where routes are...

Efficient combinatorial optimization algorithms for logistic problems

Papapanagiotou, Vasileios ; Gambardella, Luca Maria (Dir.) ; Montemanni, Roberto (Codir.) ; Schmidhuber, Jürgen (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO011.

The field of logistics and combinatorial optimization features a wealth of NP-hard problems that are of great practical importance. For this reason it is important that we have efficient algorithms to provide optimal or near-optimal solutions. In this work, we study, compare and develop Sampling-Based Metaheuristics and Exact Methods for logistic problems that are important for their...

The importance of geographical proximity : Evidence on the concentration of firms, culture and political ideologies

Mantegazzi, Daniele ; Maggi, Rico (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO008.

This dissertation proposes three empirical essays focusing on the importance of geographical concentrations along various dimensions in regional economics, dealing with topics regarding agglomeration spillovers, firm performance, culture and soft institutions as well as the geographical concentration of political ideologies. The first chapter aims at empirically verifying whether agglomeration...

Efficient tree-based content-based routing schemes

Khazaei, Koorosh ; Carzaniga, Antonio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO009.

This thesis is about routing and forwarding for inherently multicast communication such as the communication typical of information-centric networks. The notion of Information-Centric Networking (ICN) is an evolution of the Internet from the current host-centric architecture to a new architecture in which communication is based on “named information”. The ambitious goal of ICN is to...

Analysis and optimization of task granularity on the Java virtual machine

Rosà, Andrea ; Binder, Walter (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO008.

Task granularity, i.e., the amount of work performed by parallel tasks, is a key performance attribute of parallel applications. On the one hand, fine-grained tasks (i.e., small tasks carrying out few computations) may introduce considerable parallelization overheads. On the other hand, coarse-grained tasks (i.e., large tasks performing substantial computations) may not fully utilize the...

Move people or move the plant? : Business travel and relocation choices of firms

Rossi, Federica ; Maggi, Rico (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO007.

This dissertation proposes three empirical essays on firms’ location-related behaviour, focusing on two strategic issues: business travel plans and relocation choices. The first chapter studies the potential impact on business travel of the future high-speed railway line project, called AlpTransit, which in the meantime links Lugano, the small economic hub of the southern part of...
