Power Laws in Object Oriented Systems Architectures

Acknowledgment During my PhD course I have been working as a part of a wide group, whose main research topics have been and still are located in the field of Software Engineering, with a special interest and attention to the Agile Methodolo-gies and to the software systems and processes modeling. My work, study and research activities have been always related to the work, study and research activities of other people within such group. Thus, I must and want to thank all of them. Especially, thanks to Prof. Michele Marchesi for his guidance in the course of my research and academic experience. Thanks to the great Stefano Chiodo Tuveri, who actively contributed to the design and implementation of the parsing tools and to the the analysis of data results. Thanks to the Agile Group and to the Agile Gruppo. Grazie alla mia Famiglia, sempre presente. Senza di loro non sarebbe stato possibile.
