The journal may consider the following types of scholarly manuscripts:

• Original research articles
• Review articles
• Short communications
• Technical notes
• Case studies
• Methodological articles
• Editorials and invited scholarly contributions

All submissions must be original, relevant to the journal's scope, and not under consideration by another journal at the time of submission.

Manuscripts submitted to JTSES are initially assessed by the editorial team for relevance to the journal's scope, basic scholarly quality, originality, completeness, and compliance with the journal's submission requirements.

Manuscripts that pass the initial editorial assessment are normally sent to independent subject specialists for peer review. Reviewers are requested to assess the manuscript's originality, methodology, technical accuracy, clarity, relevance, use of evidence, presentation of results, and contribution to the field.

Editorial decisions may include acceptance, minor revision, major revision, resubmission for further consideration, or rejection. Authors may be required to provide a detailed response explaining how the reviewers' comments have been addressed.

The final publication decision is made by the Editor-in-Chief or an authorized editor based on the reviewers' reports, the authors' responses, editorial assessment, and compliance with the journal's policies.

JTSES provides immediate open access to its published scholarly content. Readers may access and read published articles through the journal website without a subscription or access fee.

The journal supports the wider dissemination of scientific and engineering knowledge by making research accessible to researchers, students, professionals, institutions, and the public.

Authors retain copyright in their published work, subject to any publication agreement and license accepted during the submission and publication process. Authors grant the journal the right to publish, distribute, archive, and identify itself as the original publisher of the article.

Authors are responsible for obtaining permission to reproduce copyrighted figures, photographs, tables, datasets, or other third-party content included in their manuscripts.

The applicable user license should be displayed on each published article. Authors and readers should consult the license statement accompanying the individual article to understand the permitted uses of the published work.

JTSES is committed to maintaining integrity, transparency, fairness, and accountability in scholarly publishing. Authors, editors, and reviewers are expected to act responsibly and disclose information that may affect the evaluation or publication of a manuscript.
