Acknowledgments

I would like to acknowledge and deeply thank numerous selfless individuals - students, colleagues, friends, and family members - as well as various institutions - professional associations, agencies, schools, and companies - whose availability, support, collaboration, professionalism, kindness, and patience, in one way or another, influenced the creation of this book.

First and foremost, I would like to thank my spouse, Tanja, and daughter, Lana, for their endless love, encouragement, understanding, and patience, without which I could never complete this book. I would also like to acknowledge my extended family in Serbia, Croatia, North Macedonia, and Sweden and all my friends for their continuous support, comprehension, kindness, and laughter, which made right ambience for this book to happen.

My career in Structural Health Monitoring (SHM) would probably not happen, and thus, probably, neither this book, without generous support, great mentorship, and dear friendship offered by Prof. Jean Claude Badoux, former President of the Swiss Federal Institute of Technology in Lausanne (EPFL); Prof. Leopold Pflug, my PhD adviser in the Laboratory of Stress Analysis (IMAC) at the EPFL; Nicoleta Casanova and Dr. Daniele Inaudi, the founders of SMARTEC, Switzerland, my former employer; and Princeton University, my current employer. The extraordinary intellectual vigor, exceptional collegiality, and highly professional yet relaxed settings at IMAC-EPFL, SMARTEC, and Princeton University, and in particular, at Princeton's Department of Civil and Environmental Engineering, resulted in a productive ambit for this book to germinate and grow.

I would like to make a very special thanks to the former and current members of my research group, SHMlab at Princeton University, i.e., undergraduate, graduate, and visiting students, as well as visiting scholars, whose work has been related to SHM and who have been essential in performing the research and realizing several applications shown in this book:

Additional special thanks go to Prof. Daniele Zonta, University of Trento, Italy, and Prof. Jerome Lynch, Duke University, USA, for their enormous influence on my academic career and thinking and for being such great role models and dear friends.

Concepts and ideas developed in this book could not be generated without interactions, discussions, and friendship with many dear colleagues whose research, presentations, talks, workshops, and wisdom helped shaping ideas and advancing the field of SHM.
