Instructions for Authors

The authors can submit their manuscripts throughout the year in the template provided on the Proceedings’ website. Each manuscript contains data about the authors, abstract, keywords, clearly separated (with sub-headings) introduction, essential part with the methods used, possibly an experiment or a numerical example, concluding remarks with a description of the claims for scientific contribution, references, and acknowledgment. The manuscripts must contain original, own research by the authors, not published elsewhere at the time of submission. The manuscripts have to exclude borrowed ideas and data or texts without the permission of the authors who have previously published them.

The Guidelines on Publication Ethics, together with the Paper Template and Copyright form are approved by the Editorial Board and are announced on the website.

Тo write the paper use Microsoft Word. A detailed template can be found here.

Prepare Your Paper Before Styling
Before you begin to format your paper, first write and save the content as a separate text file. Complete all content and organizational editing before formatting. Please note sections A-H below for more information on proofreading, spelling, and grammar.
Keep your text and graphic files separate until after the text has been formatted and styled. Do not use hard tabs, and limit the use of hard returns to only one return at the end of a paragraph. Do not number text heads-the template will do that for you.

Using the Template
After the text edit has been completed, the paper is ready for the template. Duplicate the template file by using the Save As command, and use the naming convention, such as paper_First_A_Author_year.doc for the name of your paper. In this newly created file, highlight all of the contents and import your prepared text file. You are now ready to style your paper; use the scroll down window on the left of the MS Word Formatting toolbar.


Paper Format
Please follow this specification when preparing the final version of the manuscript. Papers not complying with it (especially in layout geometry and typesetting) will not be included in the proceedings. Additionally, all papers will be reviewed by a proofreader.

Page layout
The paper should be composed using the A4 paper size (210 mm x 297 mm). The left and right margins should be 18.5 mm, while the top and bottom margins should be 20 mm.
The paper should be set in two columns with a 5 mm column separation. Please, equalize the length of the columns on the last page
The full paper can be between 4 and 8 pages in length. Pages should be without page numbers.


Typesetting
All paragraphs should be indented at 3.6 mm.
Times New Roman 10 pt font should be used for normal text in the body of the paper.


Title and author name(s)
The paper title and the author's names appear on the first page and should be set centered across the full page width. The title is set in 24 pt size. The author names appear below the title in 11 pt size, normal face. Paper titles should be written in uppercase and lowercase letters, not all uppercase. Full names of authors are preferred in the author field but are not required. Put a space between authors' initials. The complete affiliations of the authors should be set in a footnote on the first page of the paper.

Abstract
The paper should start with an abstract giving a short overview of the discussed matter and the presented results. The abstract must be between 150–200 words. The abstract should be set in 9 pt font for abstract and 9 pt italic font for the word “Abstract.”


Section headings
A regular paper may be divided into a number of sections. Section titles (including references and acknowledgment) should be typed using Times New Roman 10 pt font in the Small caps option, centered. For numbering use Roman numerals.
The subsection headings appear in 10 pt italic font and they are enumerated by capital letters followed by periods (“A.”, “B.”, etc.)and are flush left above their sections. The first letter of each word is capitalized.

Equations
Equations are centered within columns. You will need to determine whether or not your equation should be typed using either the Times New Roman or the Symbol font (please no other font). The equations may have a reference number placed on the right. The reference number should be enclosed in parentheses.


Figures and tables
Figures and tables should be placed as close as possible to the text where they are first referenced. Figures should be numbered in the order of appearance in the paper. Figures should be positioned within a single column or they can span two columns. In the latter case, they should be placed at the top of a page. Place figure captions below the figures; place table titles above the tables. The captions are centered within a column. If your figure has two parts, include the labels “(a)” and “(b)” as part of the artwork. Please verify that the figures and tables you mention in the text actually exist. Use the abbreviation “Fig.” even at the beginning of a sentence. Do not abbreviate “Table.” Tables are numbered with Arabic numerals. Table caption should be written using Times New Roman 9 pt Small caps font.


References
A list of references should appear at the end of the paper as a separate unnumbered section. References should be listed in the order of appearance in the paper. Use square brackets for the reference list and when referring to references in the text. The sentence punctuation follows the brackets [1]. Multiple references [2], [3] are each numbered with separate brackets [1]–[3].
When citing a section in a book, please give the relevant page numbers [1]. In sentences, refer simply to the reference number, as in [2]. At the beginning of a sentence using “Reference [2] shows ....” References [4], [5] and [6] representing book (when available online), journal (when available online), and report and handbook (when available online), respectively.
Place the actual footnote at the bottom of the column in which it is cited. It is recommended that footnotes be avoided (except for the unnumbered footnote on the first page).
Please note that the references at the end of this document are in the preferred referencing style. Give all authors’ names. Papers that have not been published should be cited as “unpublished” [7]. Papers that have been accepted for publication, but not yet specified for an issue should be cited as “to be published” [8].
Reference [9] shows a basic format for dissertations (Ph.D.). Finally, Reference [10] and [11] shows a basic format for patents and standards.

The Simple Text Query form (STQ) allows the researchers to retrieve existing DOIs for journal articles, books, and chapters by entering a reference or reference list into a simple query box. Non-members can also use Simple Text Query to match references with DOIs.

Abbreviations and Acronyms
Define abbreviations and acronyms the first time they are used in the text, even after they have already been defined in the abstract. Abbreviations such as CMOS, FPGA, SI, ac, and dc do not have to be defined. Do not use abbreviations in the title unless they are unavoidable.

Units
Use SI units. If you must use mixed units, clearly state the units for each quantity in an equation.

File Formats for Graphics
Format and save your graphics using a suitable graphics processing program that will allow you to create the images as PostScript (PS), Encapsulated PostScript (.EPS), Tagged Image File Format (.TIFF), Portable Document Format (.PDF), or Portable Network Graphics (.PNG) sizes them, and adjusts the resolution settings. If you created your source files in one of the following programs you will be able to submit the graphics without converting to a PS, EPS, TIFF, PDF, or PNG file: Microsoft Word, Microsoft PowerPoint, or Microsoft Excel.

Sizing of Graphics
Most charts, graphs, and tables are one column wide (3.3464inches / 85 millimeters) or page wide (6.88 inches /175 millimeters). The maximum depth a graphic can be is 8 inches (203.2 millimeters). When choosing the depth of a graphic, please allow space for a caption. Figures can be sized between column and page widths if the author chooses, however it is recommended that figures are not sized less than column width unless when necessary.

Resolution
The proper resolution of your figures will depend on the type of figure it is as defined in the “Types of Figures” section. Author photographs, color, and grayscale figures should be at least 300dpi. Line art, including tables, should be a minimum of 600dpi.


Conclusion

The conclusion should contain a summary of the research done, as well as clearly emphasize the scientific novelty of the paper. A conclusion might elaborate on the importance of the work or suggest applications and extensions. Although a conclusion may review the main points of the paper, do not replicate the abstract as the conclusion.

Appendix
Appendixes, if needed, appear before to write the acknowledgment.

Acknowledgment
Acknowledgments (if any) should appear as a separate non-numbered section before the list of references. Use the singular heading even if you have many acknowledgments.
In most cases, sponsor and financial support acknowledgments are placed in the unnumbered footnote on the first page, not here.
