Reports on Leading-Edge Engineering from the 2013 Symposium

This volume presents papers on the topics covered at the National Academy of Engineering’s 2013 US Frontiers of Engineering Symposium. Every year the symposium brings together 100 outstanding young leaders in engineering to share their cutting-edge research and innovations in selected areas. The 2013 symposium was held September 19-21 and was hosted by Du Pont in Wilmington, Delaware. The topics covered at the 2013 symposium were: designing and analyzing societal networks; cognitive manufacturing: energy: reducing our dependence on fossil fuels; and flexible electronics. The intent of this book is to convey the excitement of this unique meeting and to highlight innovative developments in engineering research and technical work.
