    I am deeply grateful to my promoter, Prof. Sandra Dulla, for her support and guidance in my master’s program. Her contribution, in the form of comments and feedback was precious to the realization of this thesis.\\
    
    I am grateful to SCK CEN for giving me the opportunity to conduct my research and for all of the resources and support they provided. I would like to especially thank my mentor, Dr. Ing. Luca Fiorito, who gave my the chance to work on this topic under his guidance and he helped me in any stage of the project with his understanding of the physical phenomena and his expertise with the tools employed. I would also like to thank Dr. Ing. Matteo Zanetti for being my co-mentor and providing valuable feedback and suggestions. Their insights and guidance were instrumental in helping me to shape my research and write this thesis.\\
    
    I am deeply thankful to my friends and family for their love and support during this process. Without their encouragement and motivation, I would not have been able to complete this journey. In particular, I would like to thank the friends that shared with me five years of adventures in Turin and who helped me to overcome the difficult moments. Similarly, I would also like to thank the colleagues and primarily the friends met during my staying in Belgium, for their collaboration during my research and especially for the environment we created together.\\
    
    Finally, I would like to extend my sincere gratitude to all of the participants in my study. Their willingness to share their experiences and insights has been invaluable to my research and has helped to make this thesis a success. Thank you for your time and contribution.I am grateful to everyone who has supported me throughout this process. Without your help and guidance, this thesis would not have been possible.
