Author Guidelines

1. Formatting and submitting the paper manuscript
These guidelines explain how to prepare your paper using Microsoft Word 2010 (or above).
It is highly recommended to use the buttons from the ribbon “TUV AJ Paper Formatting Macros” of the current template to format all different type of content of your paper. User manual how to use the buttons from that ribbon can be found included in the archive of the template. The paper must be minimum 5 pages, including tables, figures, formulas, references and acknowledgement. There is no upper limit of the pages number. The number of co-authors in the paper, including the main author, should not exceed five persons, and they must have real contribution to the submitted work. There is no limit to the number of papers in which an author or co-author can participate. Please, submit your Microsoft Word files only using online submission system in the AJTUV Platform. To make a successful submission you must login (or register and login after that) as an Author and complete the 5-step process to submit your Microsoft Word paper file and corresponding metadata. Sending papers by mail, courier or e-mail to the Section editors or to the Publisher will not be further processed!
Remember that no error corrections will be made by the Section editors, Reviewers or Publisher. Papers that are not formatted according to requirements of this template will be returned to revision before peer reviewing. Submissions that are found not to have all the necessary metadata entered will not be submitted for peer reviewing and will not be published in the Annual Journal of TU-Varna.

2. Page layout
Use 210 x 297 mm (A4 size) paper size (W x H mm) and adjust the margins to those shown in the Table 1. Do not add any page numbers. If you use current template you do not have to make any changes in page layout of the document.

2.1. Formatting the title, authors and affiliations
2.1.1 Formatting the title
The title is set in bold 16-point Times, Times Roman or Times New Roman, centered. The first letter of the title should be capitalized with the rest in lower case. You should leave 0 mm of space above and 24 mm below the title. No commas or hyphenation is allowed in the title.

2.1.2 Formatting author names, author affiliations and corresponding author contact
The style for the names is First Names, typed in italic 11-point Times, Times Roman or Times New Roman, then Last Name, typed in 11-point Times, with a comma after all except the last author, which is separated by comma + “and”. Do not use academic or scientific titles before or after author names.
Affiliations of authors should be typed in 8-point Times, Times Roman or Times New Roman. They should be preceded by a numerical superscript corresponding to the same superscript after the name of the author concerned. Please ensure that affiliations are as full and complete as possible and include the country. Corresponding author is usually the first author, or the co-author who makes submission of the paper and his/her email should be given in the field “Corresponding author contact:”

2.2. Formatting the text
The normal text of your paper should be formatted as follows:
11-point Times, Times Roman or Times New Roman. The text should be set to single line spacing. Paragraphs should be justified.  The paragraphs should be indented by 5 mm.
The use of sections or subsections to divide the text of the paper is optional and left as a decision for the author. Where the author wishes to divide the paper into sections, the buttons H1, H2, H3, or H4 from the ribbon “TUV AJ Paper Formatting Macros” of the current template can be used.

3. Figures and tables
Figures and tables, as originals of good quality and well contrasted, are to be in their final form, ready for reproduction, inserted in the appropriate place in the text. Try to ensure that the size of the text in your figures is approximately the same size as the main text (11 point). Try to ensure that lines are no thinner than 0.25 point.

3.1. Captions/numbering
Captions should be typed in 10-point Times, Times Roman or Times New Roman. They should be centered above the tables and flush center beneath the figures (see Fig.1).

3.2. Positioning
Place the figure as close as possible after the point where it is first referenced in the text (see Fig. 1). If there is a large number of figures and tables, it might be necessary to place some before their text citation. Partial positioning of the same figure (or table) from one page to another is not allowed. Between the last paragraph of the text and the figures should be left one empty line.

3.3. Color illustrations
You are free to use color illustrations for your paper. Some color figures will degrade or suffer loss of information when converted to PDF, and this should be taken into account when preparing them.

4. Equations and mathematics
Equations should be centered and should be numbered with the number on the right-hand side.
                                 

It is highly recommended to use Equation Editor (Microsoft Equation 3.0) to build your equations and mathematics.

5. Discussion

Authors should discuss the results and how they can be interpreted from the perspective of previous studies and of the working hypotheses. The findings and their implications should be discussed in the broadest context possible. Future research directions may also be highlighted.

6. Conclusions

This section is mandatory. It must be added at the manuscript end.

This section is not mandatory but may be added if there are patents resulting from the work reported in this manuscript.

This section is not mandatory.  Here you can acknowledge any support given which is not covered by the author(s) contribution. This may include internal or external funding, administrative and technical support, or donations in kind (e.g., measurement equipment or materials used for experiments).

 The acknowledgements should be typed in 10-point Times, Times Roman or Times New Roman.

Citation must be in form of in-text based on APA 6th Edition (American Psychological Association). In the paper must be cited no less than 10 sources. Avoid or minimize self-citation. Only 20% of the cited sources is acceptable to be self-citations. Citations should be given in original language of the cited source. This also applies to the sources written on Bulgarian or Russian language. They should be cited using Cyrillic alphabet. It is forbidden to translate the references from the original language into English or phonetic replacing Cyrillic with Latin letters.
There are two major components to the APA author-date style - the in-text author-date citation at the appropriate place within the text of the document, e.g. (Smith, 2010), and the detailed reference list at the end of the document, named “References”, formatted as Heading1 style, without numbering and centered. All in-text citations must have a corresponding reference list entry, and the converse applies for reference list entries.

The in-text citation consists of:
Author surname(s)* (in the order that they appear on the actual publication), followed by the year of publication of the source that you are citing. (*Surname = Family name)
Include page or paragraph numbers for direct quotes eg. (Weston, 1988, p. 45). Page numbers are not normally included when paraphrasing but may be included if desired.

General notes of the reference list preparation:
All of the references in the reference list must also be cited in the text.
All references cited in text must also be included in the reference list.
List the references in alphabetical order by author surname/family name according to the first listed author. (Note: the order of the authors on a document is important do not rearrange them)
Where there are two papers with the same authors and date, order the references alphabetically by paper title and add a letter suffix to the year of publication (e.g. 2003a, 2003b, ...).
Provide organization names in full, unless they are obviously recognizable as abbreviations (e.g. APA for American Psychological Association).
In a paper, chapter or book title, capitalize only the first word of the title and of the subtitle, if any, and any proper nouns. (Note: book titles should be italicized).
In a periodical, journal, or serial title, give the title in full, in upper and lower case letters. The title should be italicized (e.g. Harvard Business Review).
APA requires use of an en dash between pagination numbers. An en dash is longer and thinner than a hyphen. Type in an en dash, or if an en dash is unavailable on the keyboard, use a single hyphen. In either case, there is no space before or after.
Check the reference details against the actual source - you are indicating that you have read that source when you cite it.

(NEW, Important!!!) Since the AJTUV is a member of the Crossref organization that provides digital object identifiers (DOI) to published papers, one of the mandatory membership obligations is to place a corresponding DOI on any reference that has a valid DOI identifier in the list of references. It is recommending that DOIs also be displayed or distributed anywhere users are directed to a permanent, stable, or persistent link to the content. Crossref DOIs should always be displayed as a full URL link in the form:

                                                  https://doi.org/10.xxxx/xxxxx

and should not be preceded by doi: or DOI:. Crossref recommends the following options:

Option 1 — use the Crossref DOI URL as the permanent link:

Example: Slavov, S., & Iliev, I. (2017, December 28). Research on the variability of the burnishing force during processing surfaces with 3D shape by using simultaneous 5-axis ball-burnishing process implemented on CNC milling machine. ANNUAL JOURNAL OF TECHNICAL UNIVERSITY OF VARNA, BULGARIA, 1(1), 6-12. https://doi.org/10.29114/ajtuv.vol1.iss1.20

Option 2 — display the text “Crossref” with a permanent DOI link behind the text

Example: Konsulova - Bakalova, M. (2018, June 30). Processing of data from complex objects through pattern recognition methods. ANNUAL JOURNAL OF TECHNICAL UNIVERSITY OF VARNA, BULGARIA, 2(1), 30 - 38. Crossref

To find the DOIs of the included references in your paper, you can use the following webpage: https://search.crossref.org/

Be consistent with your referencing style across the whole document.

When listing Internet sources in your work you should use “online sources” section for this purpose. The internet sources do not count to the minimum required number of 10 references. When giving Internet sources, it should be remembered that the goal is to make it easy for a reader to consult your sources. (This same goal is paramount when listing print sources.) For most sites, that means you should include the full URL for the page you cite in your paper (the web address that begins “http”). However, websites change, and the address you used will not always be active when your reader tries to view a source. For that reason, it is important to include both the date you accessed the site and a full account of the person, group, or organization that sponsors the site. Knowing more about the author helps readers to assess the source and sometimes, to find the source when the website has been moved or revised.

The general form of a citation from an Internet source is:
Author’s name. Date of Document. Title of Document. Title of Website. Sponsor of Website. Date of Access. URL or DOI.
