Photographs from Petri Nets 1999

This page contains some photographs from the Petri Nets 99 conference in Williamsburg, VA, USA, June 1999. They were taken by Andrew Tokmakoff and Kjeld H. Mortensen with Andrew's digital camera.


The conference was organized by the Department of Computer Science at College of William and Mary, Williamsburg, Virginia, USA. This is close to Colonial Williamsburg, the restored capital of Colonial Virginia (see photograph).
Washington DC is only 3 hours away by car. Andrew took this photograph of United States Capitol building.

Hand-over Ceremony

In year 2000 the conference will be held by the CPN group at the University of Aarhus in Denmark. In the photograph you can see Kurt Jensen, Lars Kristensen, Søren Christensen, and Kjeld H. Mortensen. Kurt and Søren constitute the organising committee chair.

It is the tradition that the organisers of the next conference serves a cultural treat from their home country in the hand-over ceremony. The CPN group served Danish beer as the photographs below reveal.
