It is our pleasure and honour to invite you to the IFAC ACA conference in Wuerzburg. This location offers a perfect mix of rich historical heritage and high-tech innovations, and can be easily reached by high speed trains (directly connecting Frankfurt, Munich and Nuernberg Airports). The University, founded in the year 1402, has been a proud home of 14 nobel laureates who have researched and taught here. This list includes Prof. Roentgen, discoverer of the X-rays and whose lab can still be visited. Current activities can be seen in a laboratory tour related to the conference topics. The city of Wuerzburg, founded 1300 years ago, is at the banks of the river Main entoured by vineyards. Several interesting medieval cities (Rothenburg, Dinkelsbühl) are in the near vicinity and Wuerzburg is also the starting point of the "Romantic Road" ending at King Ludwig's castles. Prominent touristic places to visit in Wuerzburg are the castle, hosting today museums for art, and the baroque residence of the bishop (an UNESCO world inheritage site). I am looking forward to meeting you in Wuerzburg in September to share with you the technical highlights of the the conference, as well as the cultural treasures of this region.
