The editors publish original contributions that will be a basis of elegant, effective and economic engineering designs. The Journal is interdisciplinary and includes papers from scientists and engineers in the fields of mechanical engineering, materials science, mechanics, electrical engineering, electronics, and automation. Authors are encouraged to visit https://mc04.manuscriptcentral.com/jtug for further information on the preparation and submission of manuscripts as well as information concerning the procedure after a manuscript has been accepted for publication.
2. Ethical guidelines
Authorship : Authors submitting a paper do so on the understanding that the manuscript has been read and approved by all authors and that all authors agree to the submission of the manuscript to the Journal. ALL named authors must have made an active contribution to the paper and ALL must have approved the final version submitted for publication. Participation solely in the acquisition of funding or the collection of data does not justify authorship. It is a requirement that all authors have been accredited as appropriate upon submission of the manuscript. Contributors who do not qualify as authors should be mentioned under Acknowledgements.
Acknowledgements: Under Acknowledgements, please specify contributors to the article other than the authors accredited. Please also include specifications of the source of funding for the study and any potential conflict of interest if appropriate.
Manuscript Authors: At the time of manuscript submission, the definitive list and order of authors should be provided. Any changes including addition, deletion or rearrangement of author names should be made only before the manuscript has been accepted and only if approved by the Editor-in-Chief. To request such a change, the corresponding author should provide: (a) the reason for the change in author list and (b) written confirmation (e-mail) from all authors that they agree with the change(s).
Conflict of Interest: Authors are required to disclose any possible conflict of interest. These include financial (for example patent ownership, stock ownership, consultancies, speaker's fee). Author's conflict of interest (or information specifying the absence of conflict of interest) will be published under a separate heading at the end of your manuscript.
Source of Funding: Authors are required to specify the source of funding for their research when submitting a paper. The information will be disclosed in the published article.
Copyright Assignment: Authors submitting a paper do so on the understanding that the work and its essential substance have not been published before and is not being considered for publication elsewhere. The submission of the manuscript by the authors means that the authors automatically agree to assign exclusive license to Technical University of Gabrovo Publishing if and when the manuscript is accepted for publication. The work shall not be published elsewhere in any language without the written consent of the publisher. The articles published in this Journal are protected by copyright, which covers translation rights and the exclusive right to reproduce and distribute all of the articles printed in the Journal.
3. Peer review
This journal operates a single anonymized review process. All contributions will be initially assessed by the editor for suitability for the journal. Papers deemed suitable are then typically sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor is responsible for the final decision regarding acceptance or rejection of articles. The Editor's decision is final. Editors are not involved in decisions about papers which they have written themselves or have been written by family members or colleagues or which relate to products or services in which the editor has an interest. Any such submission is subject to all of the journal's usual procedures, with peer review handled independently of the relevant editor.
4. Publication charges
There are no submission fees, publication fees or page charges for this journal. Color figures will be reproduced in color in your online article free of charge. In the print version, all articles are printed in color at no extra charge.
5. Submission of manuscript
Manuscripts should be submitted online at https://mc04.manuscriptcentral.com/jtug . The use of an online submission and peer review site enables immediate distribution of manuscripts and consequentially speeds up the review process. It also allows authors to track the status of their own manuscripts. Complete instructions for submitting a paper are available online and below.
Manuscripts should be uploaded as Word (.doc or .docx) files, not write-protected. Figure files should also be uploaded as high-resolution TIF, EPS or JPEG files for printing. The text file will be automatically converted to PDF on upload and will be used for the review process. The text file must contain the entire manuscript including title page, authors’ information, abstract, text, references, tables and figures. Manuscripts should be formatted as described in the Author Guidelines below.
All manuscripts will be initially assessed by the Editor-in-Chief, which may be with the assistance of an experienced referee. Manuscripts passed editors' assessment will be referred to two experts (reviewers) in the subject, who will make recommendations to the editors relative to the quality of the manuscript. Only those receiving favourable recommendations from the referees will be accepted for publication. The Editor-in-Chief’ decision based on the reviewers’ comments is final.
In the manuscript submission, the authors are required to provide 3 suggested potential referees with their names, affiliations and email addresses. Colleagues from the authors’ institutions or those with whom the authors have recently collaborated should not be the suggested referees. The Editor-in-Chief may consider whether to select the potential referees at their disposal.
You can access ScholarOne Manuscripts at any time to check the status of your manuscript. The Journal will inform you by e-mail once a decision has been made.
When a manuscript is returned for revision prior to final acceptance, the revised version must be
submitted as soon as possible after the author's receipt of the referees' reports. Revised manuscripts
returned after six months will be considered as new submissions subject to full re-review.
6. Plagiarism check
We take plagiarism seriously. The journal use plagiarism detection software to screen the submissions. Technical review will not proceed unless your similarity report is less than 5%.
Please check your paper first and bring your similarity score down to less than 5%.
For example, you can use the following site to check: http://www.grammarly.com/?q=plagiarism&gclid=CKnXxZypzLQCFUqoPAodVz4ARw.
7. Manuscript types accepted
The Journal accepts for possible publication “Research Papers”: full-length, original research papers. The maximum length of such a manuscript is 30 pages (12 pt font size, 1.5 lines spaced, including all figures, tables and references). Papers longer than this may be returned to the author for editing before being reviewed. The contained display items (figures and tables) should not exceed 16 in number and the PDF proof generated should not exceed 10 MB in size.
Cover Letter is mandatory, which should be brief and contains the necessary message to the Editors.
8. Manuscript format and structure
Language: The language of publication is English. Articles are also allowed in Bulgarian. In this case, the article should include an extensive abstract (250 - 300 words) in English.
Structure: All manuscripts of Research Paper submitted to JTUG should include:
Title Page: The title should be brief. The author's name should be typed on the line below the title. The affiliation and address should follow on the next line. In the case of co-authors, respective addresses should be clearly indicated, as well as which author is to receive correspondence and proofs for correction. The corresponding author should, in a covering letter, state that all other authors have approved the submission.
Abstract: An abstract (about 150 - 200 words) should immediately precede the Keywords and body of the work. Abstracts should be most informative, giving a clear indication of the nature and range of the results contained in the paper.
Keywords: A few keywords or short (three-word) keyphrases, six maximum, should be provided after the Abstract.
Introduction: An introduction (normally 700~900 words must be included for the benefit of non-specialist readers.
Main text: A main text which should be divided into several parts describes the detail contents of the research/investigation, including substantial results and in-depth discussion/analysis.
The main text (and the introduction) should be in one column, using 1.5 lines spaced and 12 font size:
Use a normal, plain font (e.g., 12-point Times Roman) for text;
Use italics for emphasis;
Use the automatic page numbering function to number the pages;
Do not use field functions;
Use tab stops or other commands for indents, not the space bar;
Use the table function, not spreadsheets, to make tables;
Use the equation editor for equations;
Save your file in docx format (Word 2007 or higher) or doc format (older Word versions).
Conclusions: A succinct conclusion must be included for the benefit of non-specialist readers.
References : Indicate references by number(s) in square brackets in line with the text. The actual authors can be referred to, but the reference number(s) must always be given. Number the references (numbers in square brackets) in the list in the order in which they appear in the text. Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Citation of a reference as 'in press' implies that the item has been accepted for publication. References should be given in the following form. Examples:
Reference to a book:
 Bejan A. Advanced Engineering Thermodynamics. New York: Jonh Wiley and Sons Inc., 1997.
Reference to a chapter in an edited book:
 Korzynski M. Slide diamond burnishing. In: Nonconventional Finishing Techologies. Edited by Korzynski M. Warsaw: Polish Scientific Publishers PWN, 2013.
Reference to a journal publication:
 Maximov JT. Thermodynamic optimization of mechanical systems with dissipative processes. International Journal of Mechanical Sciences 48 (2006) 62-74.
Reference to a conference:

 Sartkulvanich P. Determination of material properties for use in FEM simulations of machining and roller burnishing: dissertation The Ohio State University, 2007
9. Tables, Figures and Figure Captions
Tables and Figures can be inserted (not necessarily) in the main text for reviewing. For the purpose of production, each complete figure and table should be on a separate page attached to the text. All photographs, charts and diagrams should be referred to as "'Fig.'" and numbered consecutively in the text. Tables and Figures should be submitted in a form suitable for direct reproduction with the lettering large enough to be legible after the diagram has been reduced in size for printing. The maximum size for submission is A4.
Preparation of Electronic Figures for Publication: Although low quality images are adequate for review purpose, print publication requires high quality images to prevent the final product being blurred or fuzzy. Submit EPS, TIFF or JPEG files only. MS PowerPoint and Word Graphics are unsuitable for printed pictures. Do not use pixel-orientated programmes. Scans (TIFF only) should have a resolution of at least 300 dpi (halftone) or 600 to 1200 dpi (line drawings) in relation to the reproduction size.
Number tables consecutively in accordance with their appearance in the text. Avoid vertical rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the article.
Ensure that each illustration (and table) has a caption. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.
