It is recommended to store the presentations on USB drive and copy them to the PC in the auditorium sufficiently early, latest during the break before the respective session.
If necessary, you can use your own laptop or notebook for the presentation. Be aware, however, that there may be difficulties with specific connections required for Macbooks.
For most presentations, a total time of 20 minutes duration is scheduled. Please make certain to reserve sufficient time for speaker exchange and for discussion after your presentation.
