ABSTRACT SUBMISSION AND REGISTRATION

Each abstract accepted for inclusion in the conference program requires at least one author to be registered to make the oral/poster presentation. Abstracts without a presenting author already registered with payment of the required fee received by 31 July, 2026 will NOT be included in the conference program.

​

Registered Authors can submit a second abstract with an additional cost.

​

Authors who wish to submit a full paper for the conference will have the opportunity to be considered for publication in COMPEL. The full paper must then be submitted by the day of the conference.

POST-CONFERENCE JOURNAL PUBLICATION OPPORTUNITY

Authors who wish to have their work considered for possible post-conference publication in a scientific journal are kindly asked to select the dedicated checkbox during registration.

This will help the Organizing Committee estimate the number of contributions interested in journal publication. The Editorial Committee will select the most relevant submissions and invite the corresponding authors to prepare a full paper, to be submitted before the start of the conference.

Authors wishing to submit a full paper for journal consideration must complete their registration by 1 July, corresponding to the early registration deadline. 

Contributions by authors who register after this date will be included in the conference program, provided that registration is completed by 31 July.

Selected papers will be considered for publication in COMPEL, with which an agreement has already been signed. All selected papers will be subject to the standard peer-review process of the respective journals.

The abstracts accepted for presentation will be published on the conference website, provided that registration is completed by 31 July.
