The article can be divided into sections that can contain subsections.

The article structure must contain the following items.

1) The paper title should be concise, clear, informative, expressive, reflect the content of the article and to attract the reader's attention. The maximum title length is 10-12 words. Only the standard abbreviations can be used and the formula can not be used in the title.

2) The list of authors contains the surname and initials of each author in the nominative case, his (her) academic degree and academic rank, position and place of work, the city and country of residence. The names of contributors for the collective article are listed in the sequence on their choose.

4) Abstract is a brief and accessible for the nonspecialist characteristic of article in terms of its purpose, content, type and form which allows to determine the main content of the article, to determine its relevance and to decide whether to refer to its full text. The abstract should be informative, meaningful (reflect the main content of article and results of researches) and structured (reflect logic description of the results in the article), should contain a general description of the research topic and the problem being solved, the object, and the aim of scientific research, description of the method of research, the description of scientific novelty and practical significance of the work, the main results and conclusions, the importance of the study, the contribution of paper into the corresponding field of knowledge. The subject, the theme and the aim of the work are mentioned if they are not clear from the title of the article. The abstract should not repeat the text of the article, as well as its name should not be numbers, formulas, tables, intratextual footnotes, references and abbreviations. The recommended average volume of abstract is 150-200 words (1000-1500 characters).

5) Key words reflects the basic meaningful content of the article, serves as a guide for the reader and used to search for articles in electronic databases and refereed journals. They are chosen from the text of article in an amount of 4-10 words or collocations and should reflect the area of science in which the article is written, the subject, the purpose, and the object of the study.

6) Introduction briefly (no more than one page) disclose the nature and the state of scientific problem (task) in general, as well as its importance and connection with scientific and practical tasks, basis and initial data for the development of the theme, the justification of the study. The urgency (the degree of importance at the moment and in the given situation) and appropriateness of the article for the development of the relevant field of science or production briefly justified by the critical analysis and generalized comparison with known solutions of the problem. The object of study (process or phenomenon, generating a problematic situation and chosen for the study) and the subject of study (contained within the object) are described. The aim of the work and tasks that need to be addressed to achieve this aim are formulated (usually these statements starting with verbs: to develop, identify, justify, etc.).

Introduction gives introductory information about theme of the article, which will enable the reader to understand and evaluate the results of the present study without further addressing other literature sources, describes the gaps and contradictions in research on problem to be solved.

7) Problem statement (of about half a page) gives a clear formal mathematical formulation of solved problem: contains the source data (input variables) and the desired results (output variables), results quality evaluation criteria and constraints, necessary definitions. This section should not contain any analysis or interpretation of data and research.

8) Review of the literature contains theoretical core of the study. It briefly (no more than two pages), critically describes, evaluates and summarizes the work of predecessors (such as publications, which have begun to solve this problem, as well as recent publications), outlines the main stages in the development of scientific thought on problem to be solved, highlights the unsolved part of the overall problem and determines the place of the article in solving problem, justifies the choices of research areas. This section clarifies, concretizes, complements and extends the material of introduction and serves as its justification and explanation.

9) Materials and methods is a statement of basic material of research with full justification of received scientific results. General technique of research is described here in detail, so that the results can be reproduced: the sequence of the research is described, the selection of methods and models is substantiated, the essence of the proposed methods and models is presented, that which have been studied by each method is meaningfully determined. Selection of research methods should provide the accuracy of the results and conclusions, reliability and validity of the results. The theoretical information should extend rather than repeat the information contained in the introduction and in the literature review. Theoretical article describes the methods and analytical models of calculations and considered hypothesis. The experimental article describes the principles of operation and characteristics of the developed equipment, the experimentally obtained models, and the estimation of measurement errors. Previously published methods are listed with reference to the source only. The article describes in detail the proposed changes only.

10) Experiments: succinctly describes the general scheme of experiments, used equipment and the source data, so that any competent specialist could reproduce experiments in his laboratory, using only the text of the article.

11) Results is a representation of experimental or theoretical data obtained in the paper, demonstrating that the new problem solution is obtained, and that the work is a significant step forward in comparison with the previous studies. Data should be presented in the processed form (tables, graphs, diagrams, equations, photographs, drawings) with a description of that is shown in the illustrations, short summarizes comments and statistical estimates. The results should be presented clearly and concisely, with sufficient information to assess the reached conclusions. It should be obvious why the analysis of these data are selected. This section describes only the facts and analysis. The Interpretation and comparison with analogues should be described in the "Discussion" section. Theoretical papers include the results of research carried out by such methods of cognition as abstraction, synthesis, analysis, induction, deduction, formalization, idealization, modeling: the substantive provisions and ideas must be formulated, which will be further analyzed, with the subsequent conclusion. The empirical articles use a variety of theoretical methods, mainly based on practical methods of measurement, observation, experiment, etc. The articles based on computational work must specify the type of used finite element, boundary conditions and input parameters.

12) Discussion includes analysis, interpretation, and evaluation of reliability and significance of the results, but does not repeat them. Obtained results are compared with similar results of other authors. The similarities and differences with other studies are explained. The limits are specified and practical application of research results is proposed. The appropriateness of further research is justified. The discussion should be more theoretical, generalizing, abstract in comparison with the results.

13) Conclusions contain a brief (no more than one page) formulation of solved scientific problem (task), the most important received scientific and practical results that helped to solve a scientific problem, conclusions and recommendations on scientific and practical use of the results obtained, a description of the prospects (directions) for further research in this area. Scientific novelty of the results should be arranged as argued, briefly and clearly. Each scientific principle is formulated to determine the degree of novelty of the results (firstly obtained, improved, received further development), main essence of the principle, and differences of the obtained results from the previously known, indicating an effect that achieved (which allows to increase / decrease ...). Applied results (devices, techniques, schemes, and algorithms) can not be attributed to scientific novelty. Practical significance of the results describes how to use research findings or recommendations for their use. Conclusions should contain achieved qualitative and quantitative indicators of research, as well as recommendations for their use.

14) Acknowledgements express appreciation for the financial, organizational and technical support to individual people (listed by names indicating the position and organization) and organizations, and also reflect the article connection with the research projects, grants and scholarships (indicate the subject and the registration number of research work, as well as a source of funding).

15) Appendices, if necessary, provide additional material (intermediate proofs, formulas and calculations, auxiliary data tables). The title of the appendix give information that is material is appendix. If two or more appendices they must be numbered with capital letters. In this case, formulas, figures and tables in the appendices are numbered with the number of applications (for example, the formula (A.2) – the second formula in Appendix A, Table. B.1 – the first table in Appendix B). The editors have the right to use the appendices for article reviewing, but do not to publish them.

16) References contain a bibliographic description of the sources used in the preparation of the article. It is presented as numbered list of bibliography references in the original language in order of appearance of references in the text (Vancouver Numerical System). The works that have been cited in the text and published or accepted for publication (in the latter case, after describing the source lead phrase "in press") included in the list of references only.

All units and dimensions shall be given in the International System of Units (SI).

The numbers less than 11 must be written as words. Numbers greater than 11 and numbers less than 11 united with them in a single sentence must be written as digits. For numbers written with units should always be used only digits. All numbers in the mathematical sense must be written using the digits. The integer and fractional parts of numbers in Russian and in Ukrainian texts separated by the comma, and in English by the point. Decimal fraction less than one must always be preceded by a zero (for example, 0.123). It is advisable not to start sentences with numbers.

The ellipsis are used in mathematics to show the continuation of the expression, for example:
x1x2, …,xn; 2) x1 + x2 + … +xn; 3) i = 0, 1, 2, …, K.

The lists must consist of more than one item. The number with a bracket or with a point must be placed before each list item, or without numbering the hyphen is used. If the list items continue sentence they must be separated by semicolons, before the list the colon is used after generalizing word and each element begins with a small letter. If the list items are the individual sentences, each of which begins with a capital letter and ends with a period.

The footnotes should be used only when absolutely necessary in the form of brief notes that do not fit conveniently into the text. Footnotes can not define abbreviations.

References to literature should be numbered consecutively in the text and identified by numbers in square brackets (for example: [1, 3-7]) and entered manually without using the built-in automation capabilities of the text processing software.

Reference Preparation

Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Organization and citation of the bibliography are made in Vancouver style in sign [1], [2] and so on.

The heading of the References section must not be numbered.  All reference items must be in 12 pt font.  Please use Regular and Italic styles to distinguish different fields as shown in the References section.Number the reference items consecutively in square brackets (e.g. [1]).

When referring to a reference item, please simply use the reference number, as in [2].  Do not use “Ref. [3]” or “Reference [3]” except at the beginning of a sentence, e.g.  “Reference [3] shows …”.  Multiple references are each numbered with separate brackets (e.g. [2], [3], [4]–[6]).

The References to figures and tables are typed with a space (for example: fig. 1, table. 2). The numbers with letters in the notation of typed without spaces (fig. 1d).

Illustrations (figures and tables) are placed directly after the text, where they are referred for the first time, or on the next page. All illustrations should be referenced in the article. The number of figures and tables should be not more than five to seven and the total volume not more than two or three pages. If the article is accompanied by a large amount of illustrative material, it is published a fragmentary. The author puts it in full at Internet website and the link to it puts in the text of a paper. Graphic illustrations must comply with standards of "Unified system construction documentation" ( and "Unified system for program documentation" ( . shtml).

Figures  are placed in the text, sequentially numbered and signed below, for example: "Figure 1 - The name", and additionally contributed in a separate files in tif format with a resolution of 300 dpi. Each file must contain only one image and have a name like Fig_ #. tif, where "#" is replaced by figure number. The figure size must not exceed the width of the page (17 cm) or the width of the column (8 cm). The inscriptions on the figures must be performed using font Times New Roman of 10 pt size. Figure captions should include an explanation of graphic and text designations should be included in the text, not into graphical files. If a particular figure consists of fragments, they must be marked with letters (a, b, c, etc.) and presented on the same page. The references to them are given in the text with an indication of a lowercase letter next to the number of a figure without a space (for example, fig. 1a, fig. 2b).

Tables laconically represent numeric or factual information in a grid format. Tables created using the capabilities of MS Word (Table / Insert Table), placed in the text, numbered sequentially and captioned at the top (for example, "Table 1 - Name"). The references to tables in the text must be given with the number (for example, table 1). Typically, the table contains at least two rows (including the column headings), and two columns. Otherwise, the information can be better represented as a list. Units should be given in the column headers, and not repeated for each record in the table body. A table containing graphics (e.g., arrows in the flowchart) is probably better considered as drawing, although sometimes the drawings can be embedded into a table (e.g., chemical structures). Tables typed as a text (using a large number of spaces, without using cells) can not be used.

Formulas placed directly after the text in which they addressed and typed using the Microsoft Equation 3.0 editor built in Microsoft Word. Formula numbered in parentheses on the right side if they are referenced in the text. Large size formulas are written in a few lines. Variables in the text and formulas italicized if they are presented in Latin letters. Greek letters and symbols of operators and functions (min, max, sin, cos, tg, ctg, etc.) do not italicized. In formulas and mathematical notation it is prohibited to use Cyrillic letters. Explanation of symbols and values of the numerical coefficients, which are included in the formula must be given in section "Nomenclature".

The numbering of figures, formulas and tables in the article text is sequential at on one level.

Articles that do not meet these requirements will not be considered.

Submiting the article to the journal, authors hereby assume full responsibility for the copyright compliance of other individuals and organizations, the accuracy of citations, data and illustrations, nondisclosure of state and industrial secrets, express their consent to transfer for free to the publisher the right to publish, to translate into foreign languages, to store and to distribute the article materials in any form. Authors who have scientific degrees, submiting the article in the journal, thereby giving their consent to free act as reviewers of other authors articles at the request of the journal editor within the established deadlines.
