The ERCOFTAC Bulletin

This is an informal communication platform where new scientific and engineering trends are published. The Bulletin is free to members in electronic and printed form.

Alternate issues of the Bulletin are devoted to a special scientific theme; these special issues provide a snapshot of the state-of-the-art of research in a particular FTAC domain.

The Bulletin contains news from the ERCOFTAC Association, reports from Pilot Centers and Special Interest Groups, and, an Agenda announcing activities such as workshops, training schools, conference and meetings.
