The Engineered Adaptive Structures IV Conference (EAS) was
held in
EAS IV focuses on the emerging technologies based on the
concept that structures can be engineered to adapt to changing environments.
This adaptability is achieved by integrating sensing and actuating devices within
the structure together with some fun of intelligence for control purposes.
While the adaptability is common in the biological world, e.g., changes in the
skin color of a chameleon to match its environment, adaptability in engineered
structures is still very much an emerging technology. Applications similar to
this are due to advances in four major technologies that are continuing to
develop rapidly in Asia, Europe, and the
The structure of the conference permitted sessions to be
held daily along with ample time for attendees to enjoy the wonderful sights of
the Canadian Rockies. There were presentations by 22 participants Plans are underway for the next EAS to be
held in 2006 in
