Aknowledgements
This work represents the conclusion of my career as a student. Therefore I would like to thank my parents, my brother and my grand parents for always helping and encouraging me throughout all these years, sharing difficulties and enjoying happy moments with me. I would not have arrived here without their help.
A particular gratitude goes to my supervisor dr. ir. Gerard Janssen for his neverending support since the first day I decided to come to Delft. Thanks to his precious advise I was able to come through difficulties and carry out my job.
I would like to thank my mentor Marco Pausini for his constant help and for always behaving as a friend. Thanks to his daily effort I was able to overcome problems and realize this project.
A special thank goes to Prof. Umberto Mengali for being always present despite the big distance between Italy and The Netherlands and for allowing me to live this experience. I would like to thank also all the people from the Information Engineering Department of the University of Pisa, especially dr. ir. Antonio D’Amico, for their constant help.
Thanks to all my Italian friends for always being close to me in spirit during this six months far from Italy.
Finally I would like to thank all my friends in Delft who made me always feel at home and made this an unforgettable experience.
