COPYRIGHT AND LICENSING POLICY

The International Journal on Technical and Physical Problems of Engineering (IJTPE) is committed to maintaining transparency in copyright, licensing, reuse, open access, author rights, repository posting, and self-archiving. This policy clarifies the copyright ownership model and the single open access license applied to published articles.

For clarity and consistency, IJTPE Journal applies one licensing policy to its published articles: the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0). The journal does not apply CC BY or any other Creative Commons license unless this policy is formally updated on the journal website. No separate publisher’s own license is applied in addition to the stated Creative Commons license.

1. Copyright Ownership

For all papers accepted and published in IJTPE Journal, the copyright is transferred to the IOTPE Organization, in accordance with the signed IJTPE Copyright and Consent Form.

The copyright holder for published articles is therefore the IOTPE Organization (International Organization of IOTPE). This transfer enables the journal to manage publication, distribution, archiving, protection of the scholarly record, and permitted reuse of the published work in a consistent and lawful manner.

2. Open Access and Licensing Model

All articles published in IJTPE Journal are made freely available online immediately after publication without subscription, access fees, pay-per-view charges, embargo period, or user registration.

Published articles are distributed under the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).

Under this license, published articles may be read, downloaded, copied, printed, searched, linked to, shared, and distributed for non-commercial academic, research, and educational purposes, provided that proper attribution and full bibliographic citation to the original publication in IJTPE Journal are given.

- No additional license: IJTPE Journal does not use a separate publisher’s own license in addition to CC BY-NC-ND 4.0.

4. Author Responsibility

Although copyright is transferred to the IOTPE Organization, authors remain fully responsible for the scientific content of their work, including originality, accuracy of data, results and interpretations, proper citation of third-party materials, ethical compliance, and obtaining permission for any copyrighted material reused in the manuscript.

The opinions, findings, and conclusions expressed in published papers belong to the authors and do not necessarily reflect the views of the journal or the publisher.

5. Rights Retained by Authors

Authors retain normal scholarly rights to use their published work for personal, academic, research, teaching, and institutional purposes, provided that the official IJTPE Journal publication is properly acknowledged and the use remains consistent with the CC BY-NC-ND 4.0 license and the signed copyright form.

- Authors may use their published work in lectures, theses, dissertations, academic presentations, teaching materials, CVs, academic profiles, and future scholarly work with proper citation.

- Authors may archive the final published version in personal, institutional, or non-commercial repositories with full citation to the original IJTPE Journal publication.

- Authors may not independently authorize commercial reuse, republication for profit, or derivative redistribution of the published article, because the copyright is transferred to the IOTPE Organization.

6. Permissions for Reuse

Any reuse beyond the permissions granted by CC BY-NC-ND 4.0, including commercial reuse, republication for commercial purposes, translation, adaptation, modification, derivative redistribution, or substantial reuse of figures, tables, images, algorithms, datasets, or text, requires prior written permission from the copyright holder.

Permission requests should be directed to IJTPE Journal / IOTPE Organization.

7. Self-Archiving and Repository Policy

IJTPE Journal permits authors to post or archive the final published version of their article in personal, institutional, or non-commercial subject repositories, provided that:

- Full bibliographic citation of the journal, issue, volume, pages, and year is included;

- The archived copy does not misrepresent the journal version;

- The deposit complies with the CC BY-NC-ND 4.0 license and the journal’s copyright and licensing policy;

8. Archiving and Preservation Policy

In the event that the journal ceases publication, IJTPE Journal will take appropriate measures to ensure that previously published content remains accessible to the academic community through its website and established archiving practices.

9. Copyright and Licensing Information on Published Articles

Copyright and licensing information should be clearly identified on the journal website, policy documents, author documents, published article records, and publication files.

Where applicable, published article pages and PDF files should state that copyright is held by the IOTPE Organization and that the article is published under the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).

10. Third-Party Materials

If a submitted manuscript includes any figure, table, algorithm, image, dataset, or substantial text taken or adapted from another source, the authors must obtain all necessary permissions before publication. Responsibility for securing such permissions rests entirely with the authors.

In particular, all journal materials should consistently state: Copyright is transferred to the IOTPE Organization and published articles are licensed under CC BY-NC-ND 4.0.

This Copyright & Licensing Policy may be updated from time to time to improve transparency, align with international publishing standards, and reflect the development of the journal’s editorial practices.
