  [Submission page] for speakers (oral and poster)  Closed.

  [Registration page] for speakers and audiences: Open

  • Speakers (oral and poster) must also complete the registration.
  • Registration fees must be paid via payvent on the registration page.

For Authors

• PDF Manuscript Submission
• Information for oral presentation
  • Each regular talk is 20 minutes (15 min. presentation + 5 min. discussion), except for invited talks.
  • Please test the connection to the projector during the break before your talk.
• Information for poster presentation
  • The poster session will be held on Thursday, November 5, from 13:10 to 14:40.
  • Each poster panel has a display area of approximately 130 cm (W) × 180 cm (H), which can accommodate an A0 poster (84.1 cm W × 118.9 cm H).
  • Some panels require tape and others use pushpins. Both will be provided at the venue.
  • The poster session will take place in the Event Hall, located in the same building. Please put up your poster in your assigned location at any time from 15:00 (tentative) on Wednesday, November 4, until the start of the poster session. The poster area is adjacent to the reception and coffee break areas, so posters can also be viewed during those times.

For Participants

• Photos (including screenshots) and video recordings of oral presentations and posters are prohibited unless specific permission is granted.

For those wishing to attend the conference for reporting or consultation purposes

• In order to find out about the rules and regulations for the recording of information at QIT meetings, please contact the QIT organizers, if possible two weeks before the deadline of pre-registration.
  If this deadline has already passed, you should still contact the organizers, even if it is only on the day of the meeting.
