ABSTRACT:
In many applications nowadays there are requirements for data that aflowa continuously (data streams). Examples include fleet management systems, temperature or other measurement monitoring, even monitoring stock prices. Of particular interest due to the large increase of devices that detect location (e.g. GPS) have applications that manage large volumes of data streams with geospatial information. This talk addresses issues of management of a large number of objects in modern such monitoring applications. In such an environment, the presence of ephemeral streams and dynamically changing data, drastically change the way the processing of so-called acontinuous queriesa is done, so as to provide answers for the position and trajectory of objects.
BIO:
Prof. Timos Sellis received his diploma degree in Electrical Engineering in 1982 from the National Technical University of Athens (NTUA), Greece. In 1983 he received the M.Sc. degree from Harvard University and in 1986 the Ph.D. degree from the University of California at Berkeley, both in Computer Science. In 1986, he joined the Department of Computer Science of the University of Maryland, College Park as an Assistant Professor, and became an Associate Professor in 1992. Between 1992 and 1996 he was an Associate Professor at NTUA, where he served as a Professor till January 2013. He is currently a Professor at the School of Computer Science and Information Technology of RMIT University in Australia. Prof. Sellis was also the Director of the Institute for the Management of Information Systems (IMIS) of the aAthenaa Research Center (www.imis.athena-innovation.gr) between 2007 and 2012. His research interests include data streams, peer-to-peer database systems, personalization, the integration of Web and databases, and spatio-temporal database systems. He has published over 190 articles in refereed journals and international conferences in the above areas and has been invited speaker in major international events. Prof. Sellis is a recipient of the prestigious Presidential Young Investigator (PYI) award given by the President of USA to the most talented new researchers (1990), and of the VLDB 1997 10 Year Paper Award for his work on spatial databases. He was the president of the National Council for Research and Technology of Greece (2001-2003) and a member of the VLDB Endowment (1996-2000). In November 2009, he was awarded the status of IEEE Fellow, for his contributions to database query optimization, and spatial data management. He has also participated and co-ordinated several national and european research projects.
