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....

The semiotics of migrants’ food : between codes and experience

Greco, Sara

In: Semiotica, 2016, no. 211, p. 59–80

This paper sets out to analyze cultural semiotics of migrants’ food and culinary practices. Moving from the perspective of the Tartu school of semiotics, which views culture both as a grammar (a set of codes) and as a set of texts, food can be characterized as a specific cultural element where grammar and text (code and experience) are woven together. International migrants live one or more...

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...
