Certificate Distribution

Oral presenters will receive a certificate of presentation from the session chair after their presentations or at the end of the session. Poster presenters will receive a certificate of presentation from the conference staff at the end of their poster session.

The certificate of presentation will not be issued, either at or after the conference, to authors whose papers are registered but not presented. Instead, the certificate of attendance will be provided after the conference.

If authors are not able to present their papers due to unavoidable circumstances, they shall provide the official certification document to request for the certificate of presentation. For more details, please contact the conference secretariat at acec@upi.edu
