Digital Technologies Research and Applications
Digital Technologies Research and Applications (DTRA) manages topical collections in order to curate papers on specific subjects. The objective is to foster a community of authors and readers who can engage in discussions about the latest research and explore new ideas and research directions. These topical collections are lead and supervised by Collection Editors who possess expertise in the respective field and oversee the editorial process for the papers. All the papers published in a topical collection are consolidated on a dedicated page of the journal's website. If you have any queries regarding a topical collection, please reach out to the Editorial Office.
