The Conference will be held in the Auditorium Maximum of the
Christian-Albrechts-University in Kiel, located centrally on the
campus (see map below).
The programme of the Conference will include an opening session and
scientific sessions with both oral and poster presentations. The
sessions will be opened by a 45 minute talk of invited keynote
speakers. Individual lectures within each topic will last 30 minutes,
including 10 minutes discussion time. During the Conference various
round-table sessions will be held to discuss special topics.

All participants are encouraged to present original software. The
following computer hardware will be available for software
demonstrations: PC-DOS, SUN, NEXT and 386-SVR4 workstations. For any
specific requirements on the equipment from your side, please contact
Dr. A.Salski (Tel. -4080) under the above address.

Registration fees after July 1, 1992 are 460 DM for ISEM members, 520
DM for non-ISEM members and 60 DM for students (ID required). For
late registration, please use the registration form from the last
page of this circular. The fees cover Conference material incl.
