A book such as this would not have been possible without the help and support of many people and institutions.
First of all, we would like to thank our base institutions—the Department of Informatics Engineering, and the Center for Informatics and Systems, both from the University of Coimbra—in the scope of which we carry out our teaching and research activities, for the provided facilities and research environment. With their effort and contributions, enthusiasm, discussions, and suggestions during several years of joint research activities and human-in-the-loop social interaction, our students and our colleagues were instrumental in making this book a reality.
We also thank IMDEA Networks Institute, in Madrid, for the support provided during Fernando Boavida's sabbatical in 2015/2016, and especially to its leading computer scientist, Arturo Azcorra, for his support; to Antonio Fernández Anta, Miguel Péon, Jeanet Birkkjaer; and Rosa Gómez for their encouragement; and to all its researchers and staff in general.
Some of the research that formed the basis for this book was carried out in the scope of financed research projects and initiatives and, thus, it is also right to thank the entities that made the referred research possible, namely the Portuguese Foundation for Science and Technology (FCT), FCT's POPH/FSE program, and the SOCIALITE Project (PTDC/EEI-SCR/2072/2014), supported by COMPETE 2020, Portugal 2020, Operational Program for Competitiveness and Internationalization ...
