Smart Cars for Safe Driving

D. M. Gavrila
Daimler R&D and Univ. of Amsterdam

Abstract: One of the most significant large-scale deployment of intelligent systems in our daily life nowadays involves driver assistance in smart cars. Driver assistance systems use sensors to monitor the car surroundings or interior. They warn the driver in case of pending danger, and even exert automatic vehicle control if necessary. As such, they have major potential to reduce accidents. 
My talk starts with an overview of currently available driver assistance. I move on to our longstanding research on active pedestrian protection, presenting, among others, a prototype system for automatic vehicle braking and evasive steering. I conclude with some thoughts on future autonomous cars.

Professional outline:
Dariu M. Gavrila received the PhD degree in computer science from the University of Maryland at College Park in 1996.  Since 1997, he has been a Senior Research Scientist at Daimler R&Din Ulm, Germany. In 2003, he was further appointed professor  at the University of Amsterdam, chairing the area of Intelligent Perception Systems (part time).
Over the last decade, Prof. Gavrila has focused on visual systems for detecting humans and their activity, with application to intelligent vehicles and surveillance. His contributions are frequently cited, he received the I/O 2007 Award from the Netherlands Organisation for Scientific Research (NWO) as well as several conference paper awards.




Research Challenges and Proposed Solutions to Improve Availability and Quality-of-Service in Future IPTV Systems

Bernd E. Wolfinger
Telecommunications and Computer Networks Division
Computer Science Department
University of Hamburg

Abstract: During the last decade the offering of TV programs via the Internet by means of an IPTV service using multicast communication has become more and more common. Currently, the largest number of IPTV subscribers is located in Western Europe and in the Asia Pacific region. In particular, France is still the leading country for IPTV and about 17 % of the French population is presently already using an IPTV service. A typical way to offer IPTV to customers (by Telcos and Internet Service Providers) is to offer this service via DSL. However, also wireless access networks such as Wi-MAX or LTE become increasingly relevant. The transmission of TV programs leads to very large bandwidth requirements within the communication infrastructure if a large number of TV channels (> 100) has to be offered in parallel and possibly also in high quality (e.g., HDTV quality). Therefore, serious bottlenecks in the communication network may occur which may lead to a temporary unavailability of some of the more unpopular TV channels.

The talk summarizes the comprehensive experiences in IPTV research (both for DSL and WiMAX access) within the Telecommunications and Computer Networks Division at University of Hamburg. In particular, emphasis will be given to our recent research results related to new measures (called ‘multicast gain’), which allow one to quantitatively assess the usage of multicast versus unicast, both, for wired and for wireless links in networks; realistic models to characterize the behaviour of IPTV users; methods to calculate the overhead resulting from multicasting and unicasting TV channels in WiMAX based IPTV systems; a new access control algorithm for TV channels offered via DSL which favours more popular channels as compared to infrequently watched ones and turns out to increase channel availability quite strongly in numerous high-load situations; algorithms to reduce either the channel switching delay or the channel unavailability in IPTV systems with users zapping channels frequently.

The research results presented should be a valuable source of information mainly for Internet Service Providers (ISPs) or Telcos offering IPTV services, but also to re-searchers, developers, (post-) graduate students, etc who are interested in the anal-ysis, assessment, tuning, construction and/or installation of efficient and highly available IPTV systems with DSL- or WiMAX-based access networks.

Professional outline:
Bernd E. Wolfinger has been with the Computer Science Department of Hamburg University as a professor since 1981, where he is presently heading the Telecommunications and Computer Networks (TKRN) Subdivision. Dr. Wolfinger has degrees from Université Claude-Bernard, Lyon/F. (Maîtrise, ‘74), University of Karlsruhe/F.R.G. (Diploma, Mathematics ‘75; Ph.D., Comp. Sc. ’79). He has spent long-term sabbaticals at IBM Research / Yorktown, N.Y. (‘85), Internat. Computer Science Institute / Berkeley, Ca. (’91,’96), as well as at Université P. et M. Curie, LIP 6, Paris (’01, ‘06). Professor Wolfinger is active in Computer Networking research since 1975, he has been responsible for numerous conference organizations and has served on a large variety of TPCs (> 100 during the last decade) and he is currently member of 5 Editorial Boards of international journals. He has been editor of books and special issues of journals; he has published more than 150 papers in areas such as High-speed & Mobile Networks and Real-time Communications (e.g. IPTV) as well as in Modeling (Simulation & Queueing Networks), Measurement, Traffic Engineering and in Performance, Reliability & QoS Evaluation.
