Study of spatial-time inhomogeneity of serrated plastic flow Al-Mg alloy: using DIC-technique

The aim of the present paper is the investigation of temporal instabilities and spatial localizationdue to the Lüders behavior, the Portevin–Le Chatelier effect and the shoulder or necking effect during uniaxialtension tests of aluminum-magnesium alloy. This paper presents the brief description of the test procedure andexperimental results of carrying out research by the combined use of a servo-hydraulic biaxial test systemInstron 8850 and a non-contact 3-D digital image correlation measurement system Vic-3D. The digital imagecorrelation is a highly effective computer-vision-based technique, which provides estimation of thedisplacement and strain fields on specimen surface by matching the reference subsets in the undeformed image(before loading) with the target subsets in the deformed images (captured during test). The evolution ofinhomogeneous axial strain and axial strain rate fields has been illustrated for each stage of material’sdeformation. To estimate the kinematics of serrated or jerky flow due to the strain bands propagation, the strainversus time curves and strain diagrams are given here. The experimental results show the recurrence in thestrain distribution leveling along the specimen gauge. The changing between the macroscopic localization of theplastic flow, namely the running of the Lüders and PLC bands and the recovery of strain field homogeneity, hasbeen observed

Migration safety in education: Adaptation of migrant students to conditions at higher educational establishments

The topicality of the problem under study stems from the changed geopolitical and socioeconomic conditions in Russia, which resulted in uncontrollable international and migration processes, changes in the ethnic composition of territories, worsening of ethnic and social relations of migrants and members of the society receiving them, search for educational paradigms complying with new conditions of the country's development. The aim of the research is to determine specific features relating to adaptation of migrant students to conditions at higher educational establishments and to draw up a programme of social, psychological and pedagogical activities to adapt migrant students to conditions at higher educational establishments. The leading research method is an experimental one, which enables us to fully consider the problem of adapting migrant students to conditions at higher educational establishments. The article outlines a system of social, psychological and pedagogical help to migrant students needed to optimise a process of their adaptation to an educational environment. The programme is aimed at creating social, psychological and pedagogical conditions for the efficient interaction of all members of an educational process, as well as full fulfillment of a person in conditions of a poly-cultural educational process. Teachers, curators, heads of subdivision and administrations of higher educational establishments may find the materials of the article useful. © Authors

Vocational training in sport and recreation micro-enterprises as an education project

This study appears urgent due to the need to create new jobs in the sport and recreation sector and to update the existing approach to vocational training in a micro-enterprise. This paper proposes an education project as a form of vocational training in such conditions. The authors aim to comprehend the current issues of pedagogical design for the transfer of experience within a micro-enterprise of the sport and recreation sector and to determine the conditions for effective educational interaction of micro-enterprise employees. This problem is addressed with a combination of the systematic approach and activity-based learning. This makes it possible to present the process of pedagogical design of vocational training in the conditions of a micro-enterprise as systematic activity of individuals in developing the professional competencies of a sport and recreation worker. The authors used theoretical and empirical methods. The theoretical methods were analysis of the psychological, pedagogical, sociological, scientific-methodological and specialized literature on the studied problem; the systematic approach to the definition of the problem and the formation of the research terminology; and analysis of the legal acts. The empirical methods were pedagogical observation; study and generalization of pedagogical experience; pedagogical design; questioning; conversation; interview; performance analysis; and expert evaluation method and integration of expert opinions. © 2018 Authors

Production function and production cycle: specific features of municipal entities of the Perm territory

Objective: to identify the upward and downward waves of production cycle in the Perm region municipalities and to characterize fluctuations using the production function model.Methods: economic and mathematical modeling, correlation and regression analysis, time series analysis.Results: statistically significant models are constructed characterizing the dynamics of the volume of shipped goods of own production, works and services performed, for each municipality and the Perm region as a whole; the trend and cyclic component of each time series are identified; the production cycle duration is determined. Statistically significant production functions are constructed; the main indicators of labor and capital resources efficiency are defined; their values’ dynamics is analyzed in the context of the revealed cyclic fluctuations. The resources efficiency indicators, calculated by means of production function, showed that the amount of the produced goods in the Perm region municipalities is most influenced by labor resources consumption. It is found that the fluctuations of average and marginal efficiency of resource use, as well as the replacement rate, include a cyclic component, which is synchronized with a one-year lag with the cyclic fluctuations in the volume of shipped goods of own production, works and services performed.Scientific novelty: the combination of cyclicity analysis and production function modeling to identify the factors that have the greatest impact on the economic development of the Perm region municipalities. This aspect forms the novelty of the work, which consists in substantiated disclosure of trends in the economic development of the Perm region municipalities, based on economic and mathematical modeling.Practical significance: the main provisions and conclusions can be used by regional authorities in the development of the state regional anticyclical policy to ensure the coherence of regulatory measures and the formation of the necessary conditions for sustainable economic development of the Kama region
