For the final registration of accepted papers (including issuance of paper certificates and publication in conference proceedings), it is mandatory for the presenting author to register for the conference. The registration fee is 700,000 Toman per person. If a presenting author has more than one paper, a fee equivalent to half the registration cost is required for each additional paper. By paying the registration fee, attendees will receive a conference souvenir and can participate in all conference programs, including keynote speeches, specialized panels, workshops, and paper presentation sessions. However, obtaining meal vouchers for lunch on the first and second days of the conference requires separate registration and payment (400,000 Toman per lunch).
