2011 IZOD IndyCar World Championship
The 2011 IZOD IndyCar World Championship was the final race of the 2011 IZOD IndyCar series schedule. The event took place at Las Vegas Motor Speedway in Clark County, Nevada on October 16, 2011. The race was stopped following a major accident triggered by drivers trying to avoid light contact between Wade Cunningham and James Hinchcliffe. 15 cars were involved in the wreck, which resulted in the death of two-time Indianapolis 500 winner and 2005 series champion Dan Wheldon. After a delay of over two hours, IndyCar decided to abandon the remaining 188 laps after word of Wheldon's death was relayed to the drivers, though the drivers did complete a five-lap salute in honor of Wheldon.
International Conference on Database Theory
The International Conference on Database Theory (ICDT) is an international research conference on foundations of database theory, and has been held since 1982. It is frequently also called as the PODS of Europe. Since 2009, ICDT has been held jointly with the EDBT, a research conference on systems aspects of data management. Until 2009, the conference used to happen biennially. The conference now happens annually at a location typically within Europe. ICDT has been instrumental in developing a flourishing research community within Europe, working on problems in database theory.
