Orclever Proceedings of Research and Development (OPRD) is an open access journal dedicated to publishing findings resulting from conferences, congresses, and similar events, in all areas of engineering and natural science. OPRD has two peer review processes: for conference, congress, and similar event volumes, the peer review process is handled by the conference scientific committee, and the review method as well as reports number are decided by the conference organizers' requirements; for standalone papers, the process is handled by researchers as a single-blind assessment with at least one independent reviewer, followed by a final acceptance/rejection decision by the Advisory Board Members of OPRD.
