	The Emerging Science of Complex Networks + - Abstract Click to collapse Information is an increasingly important entity in the information society. Networks are the vehicles over which information is transported. We discuss the tools for characterizing the emerging complex networks and discuss their characteristics, especially in view of the fact that common user networks are being required to carry mission-critical information in an increasingly heterogeneous environment. We also posit that networks can be equipped to address the sometimes conflicting needs of privacy and security of its clients, in an equitable manner. Pramode Verma, University of Oklahoma-Tulsa, USA. + - Bio Click to collapse Pramode Verma is Director of the Telecommunications Engineering Program in the School of Electrical and Computer Engineering of the University of Oklahoma-Tulsa. He also holds the Williams Chair in Telecommunications Networking. Prior to joining the University of Oklahoma in 1999, Dr. Verma held a variety of professional and leadership positions in the telecommunications industry at AT&T Bell Laboratories and Lucent technologies. His last position with Lucent Technologies was as Managing Director, Business Development-Global Service Providers Business. Dr. Verma obtained his doctorate in Electrical Engineering from Concordia University in Montreal, Canada in 1970 and an MBA from the Wharton School of the University of Pennsylvania in 1984. He is the author/co-author of over 100 publications and several books in telecommunications, computer communications, and related fields. He is a past president of the International Council for Computer Communication, a Washington D.C.-based global organization; a senior member of the Institute of Electrical and Electronics Engineers, New York, and is registered as a Professional Engineer, Province of Ontario, Canada.
	Green Wireless Networking: Sustainability Through Cooperation and Adaptation + - Abstract Click to collapse One third of the Internet population accesses online resources using wireless technologies, and forecasts predict that in a few years the mobile Internet will be bigger than the wired Internet. Unfortunately, the Internet is accounted for around 2% of carbon emissions in the atmosphere, where most energy consumption is associated with the core and access networks as well as data centers. As a consequence, a clear need emerges towards design of green solutions for wireless access and networking, to optimize power usage. The seminar will introduce the challenges related to energy efficiency in wireless networks and describe how cooperation and adaptation could represent viable approaches to address the main issues. Concrete examples will be presented, taken from the current activities within the EU GREENET research project. Fabrizio Granelli, University of Trento, Italy. + - Bio Click to collapse
	Leveraging the Information Society: accrual and exploitation of Big Data + - Abstract Click to collapse The talk addresses the growing importance of Big Data for really making the Information Society a reality. Data are now being created every minutes of our life and they are progressively aggregated. Most of them are either not accessible or when they are they may lead to problems (privacy, ownership, authenticity, ...). It is now the time to address these issues in a systematic way to control problems and to leverage the wealth hidden in data. Many countries, and local institutions, have started Open Data Initiatives, aiming at guaranteeing the appropriate management of data and at the same time their availability. Telecom Operators are both data generators and data managers, Indeed, they can be major players in the Big Data sectors by providing the trust and technical innovation required for developing a sound marketplace for data. The talk will outline both the technical approaches for managing Big Data and the regulatory issues. It will bring as a concrete example the activities being carried out in the EIT ICT LABS Italy in the Trentino Open Data framework and the results obtained so far. It will also provide an overview of the studies being made by TIM Brasil and Telecom Argentina in this area. Roberto Saracco, Telecom Italia, Italy. + - Bio Click to collapse
	3D Video Analysis for Immersive Interactive Virtual Services + - Abstract Click to collapse Continuous scientific and technological advances in a variety of different research fields mean that it is now possible to integrate research outputs towards technologies that support real-time realistic interaction between humans in 3D online virtual and immersive environments. This paradigm envisages an ambient, content-centric, highly flexible and secure Internet-based environment, where people can work, meet, participate in live events, socialise and share experiences, as they do in real life, but without time, space and affordability limitations. To achieve this goal, current research focuses on the integration of cutting-edge technologies related to 3D data acquisition, coding, autonomous avatars, networking, real-time rendering, physical interaction and emotional engagement in virtual worlds [1], [2]. The ability to bring a new range of 3D virtual experiences to many different everyday aspects of life via internet connectivity is indeed one of the most important challenges in the multimedia and broadcasting community over the next few years. In addition to the appealing functionalities brought by the very successful internet mediated social sites as Facebook, Flikr, LinkedIn, Foursquare and their like, real-time realistic interaction between humans in online virtual and immersive environments appears to be the next logical step in computer mediated online communication. Currently social networking support text, 2D images and video, with interaction being confined to voice and conventional video. Inevitably, the nuances and subtleties of expression and experience that we take for granted in 3D face-to-face human encounters are lost. In this talk the evolution of computer mediated 3D communication and the vision of immersive collaborative environments that support realistic inter-personal communication is presented. It is argued that recent scientific advances in a variety of different research fields is leading to emergent multimedia systems and services that support real-time 3D interaction between humans in online virtual and immersive environments. 3D technology including immersive audio-visual display systems and streaming of 3D visual information will be outlined. Such technology has been developed to such an extent in recent times that it is now considered de rigueur for ensuring the most attractive user experience. As such, advances in 3D visualisation, construction of immersive environments and rendering are all important aspects of related developments to be presented in this talk. Furthermore, new dimensions to such 3D experiences such as autonomy into avatar behaviour, security and ethical aspects, as well as, handling and representation of user emotional states, represent additional richer levels of 3D interaction that may be achievable soon. These aspects are part of ongoing research in the large integrating and cooperative Reverie [2] project and will be discussed in this talk too.
