Acknowledgments
First, I acknowledge those people who were involved in my PhD thesis work during
2002–2006. This book is based on that thesis. The research for the thesis was car-
ried out at the Tampere University of Technology (TUT), Pori, Finland, and in its
tiny satellite ofce in Turku during 2002–2005. I am grateful to Professor Hannu
Vanharanta who was my supervisor. The thesis would not have been possible with-
out his expertise, ideas, enthusiasm, and exceptional 24/7 support. The time I spent
working with him on the thesis research was an educating and fun experience for
me. I am also very grateful to Professor Waldemar Karwowski ...
