The article shows the results of applying the submodeling technology to the analysis of sheet metal structures, modeled by shell or solid elements. Criteria for the appearance of a singularity in the model and methods for finding the actual stresses in the concentration zone are shown by using the corrected geometry for solution performing.

In the article the concept is considered and the basic method of evolutionary modeling is described for their use in optimization problems

Summary: this article deals with different methods connected with the aim posi-tioning at the lessons of mathematics at secondary school. It gives some concrete examples of their usage.

On the basis of the ontological analysis of risk factors the budgeting system implementation technique in the organization of arbitrary nature differing in an opportunity to create optimum (in this or that sense) the institutional environment of implementation is offered.

TRIZ-pedagogy focused on the formation of the factor of safety theoretical and practical knowledge in materials science from the College students who have, in the future, systemic thinking and creative individuality when solving complex problems in various fields of activity.

When improving the raw and technological preparation of logging sites, mathematical modeling, software, and voluntary forest certification take an important place.

This monographic research describes the mathematical models for heat treatment of rubber products by steam heating in the autoclave. Also the calculation methods of energy losses by steam heating in the autoclave are described. The technique of calculating the energy loss during heating with steam in an autoclave is explored.

According to the authors, the major factor influencing the product yield in obtaining the mathematical model of the recycling process optimization of the mixture of bentonite clay and silted slurry of alumina production is x1 and x 2. The obtained models provide the opportunity to use the data in studying the recycling process of the mixture of bentonite clay and silted slurry.

The article presents the definition of dynamic linear neighborhood models. An algorithm for finding optimal solutions using genetic algorithm has been describes. Solution of system of linear equations is reduced to the problem of optimization. It shows the example parametric identification of neighborhood model, consisting of three parcels, as a solution to the system of linear equations with the use of a genetic algorithm and the pseudo-inversion. The authors calculated RMS and average absolute errors for model identification using genetic algorithm and the pseudo-inversion. On the basis of the developed system the researchers verified the modeling results and determined the optimal method of identifying neighborhood model.

This study is intended to unveil a correlation between metaphorical images of the US Armed Forces and ethnic stereotypes of the army subculture within the Anglophone military-political discourse. The US Army is Family metaphorical model serves as a foundation for analyzing ethnic stereotypes of mass perception of the socio-professional environment of service members. According to the authors, metaphorical modeling is perceived as a linguistic means of explication of ethnic stereotypes attributed to the US Army subculture.

The work is devoted to creation of mathematical model of the solution of problems on use of raw materials and drawing up a diet. These problems have been solved by the authors of this article by means of a graphic method in number.

The article is devoted to the capability of various financial indicators, namely domestic credit to private sector, foreign investment, government gross debt and others, influence on economic growth that is indicated as GDP level. The calculation was presented according to the scope of data for 1995–2014. The results of the investigation were compared with the overall economic situation in UAE and future growth perspectives.

The article details the use of such modern method of training as computer simulation applied to modelling of various kinds of mechanical motion of a material point in the free spreadsheet OpenOffice.org Calc while designing physics and computer science lessons in primary and secondary schools. Particular attention is paid to the application of computer modeling integrated with other modern teaching methods.

The article covers an approach to modelling of the cyclic macroeconomic dynamics, which allows to increase the accuracy of approximation of the real data in order to further forecasting of the medium-term changes in volume of gross domestic product. This approach allows to determine more accurately the turning points of cycles and to fix the changes in the amplitude and duration of the separate cycle waves. The article also covers the comparative analysis of the constructed model and the «simple-sine» model generally used at practical researches.

The scientific approaches to the integration of educational institutions in the social potential of the region are analyzed in the article. The functional model of cooperation of educational institutions and socially oriented non-profit organizations is proposed. This model taking into account the mission of the educational institution, algorithms and implementation of the logistics functions of institutional «players» third sector. As a mandatory construct of the model, the League providers of social services, the Department of social and political communications of the Government, Resource Center for Social Development, and the regional Ministry of Education and Ministry of Social Development are considered.

Mathematical simulation to determine the optimal shift points to initiate movement at the maximum permissible speed in low gear and get the highest possible intensity of acceleration and minimize the time in the area of movement.

A brief analysis of patents on the design of jaw crushers. A new decision on the design of jaw crusher for the disintegration of the solid rock.

This article presents mass media activities as a possible source of professional socialization, adequateness of social process informative display in the sphere of young people professional identity. It describes pattern distortion of occupational structure, presents the problem of mass media inadequate influence on students’ understanding about the choice and perspectives of their profession. The main factors which help to create student’s understanding about their professional future are examined.

In this research the authors tried to investigate and generalize theoretic and applied studies of aesthetic taste, as well as, opportunities of its productivity distribution in terms of socio-cultural, person-professional and psychological levels. The article deals with traditional outlooks upon the origin of taste and its relationship with art and its current situation of taste functioning in terms of increasing globalization, virtualization and informatization of modern society.

The article is devoted to the development of a fishpond ecosystem’s conceptual model and its quality stability verification. The choice of variables in the model is made according to the selection of fish species, goals and objectives of the research.
