  • Convergent education based on cognitive technologies

    In the process of convergence of the NBICS technologies cognitive technologies perform system role. One of the important aspects of system convergence is convergent education based on cognitive technologies. It is noted that the basic concept of the technology are cognitive models. The role and place of teaching cognitive modeling in a modern University. It is noted that, despite the widespread use of the method and of the specialized software continues to cognitive modeling is the only scientific and professional tools. His research and development performed within the discipline specialisation of the master's or postgraduate specializations. Educational technology is necessary to saturate the cognitive procedures, methods and tools. The formation and development of cognitive technologies involves the training of specialists with knowledge in the relevant field and skills of cognitive modeling. The prospects for the promotion of convergent education in the southern Federal University.

  • Socio-economic aspects of deprivation attitudes of student KChR

    The paper presents an analysis of the relationship of cognitive and affective components of deprivation installations. The research is based on empirical data from survey conducted in early 2015 in Karachay State University. As indicators of deprivation plants used cognitive and emotional evaluation of individual socio-economic security. Cognitive measured by direct survey. Emotional - technology of semantic differential. It was found that these estimates do not correlate with each other. At the statistical level of the entire set of respondents cognitive appraisal always overpriced compared to the affective. Revealed the limitations of the measurement of relative deprivation accepted by direct questioning. It is shown that the developed method for measuring the earlier emotional perception of social processes and phenomena completely solves this problem.

  • Stress analysis ballastless design of the top structure of railway track and railway tunnel lining

    Currently, there is a constant increase in train speeds and loads on the structure of railway track. In tunnels these loads are also transferred to the lining, and the stress-strain state of tunnel structures in the application of ballastless track and large axial loads requires further study. To carry out such a study developed a numerical model of a railway tunnel with a circular cross-section ballastless design path, including under-rail support, resilient layer and track concrete. As a result of the calculation model, the values main vertical stresses in the main tunnel structures. Found that with increasing loading of the wheel on the rail from 100 to 200 kN stress increases by an average of 50%. The distribution of stress affects the stiffness of the elastic layer. With its increasing vertical stress in the under-rail support non-linear decrease, and at the road concrete increases nonlinearly.

The calculations used viscoelastic model, according to which the total deformation is the sum of concrete elastic deformation and creep. We consider a rectangular cross section with symmetrical reinforcement. It is shown that because of creep stress redistribution between concrete and reinforcement arises.

  • Fibrogipsovermikulitobetonnye composites with the application of the pumice

    The development of new effective composites on the basis of technogenic raw material and local materials, which are characterized by low prime cost and improved physicomechanical characteristics, is urgent task. Deficiencies in gypsum in those binding and articles possibly as a result of the creation of composites with the use of effective fillers and dispersed reinforcement. Earlier we developed the gipsovermikulitobetonnye composites with the application of unslaked lime and withdrawals of the saw-milling of volcanic tuff. Use in the composites of pumice, basaltic fibers and portland cement will make it possible to enlarge raw-material base for obtaining the composites with the improved physicomechanical characteristics. The optimum relationship of the components of gypsum, ashes and portland cement, which would ensure obtaining composite with the improved physicomechanical properties with the smaller expenditure of binding agent is revealed. Simultaneously was investigated the influence of the grain composition of ashes on the properties of gipsotsementnoputstsolanovogo composite. Is proposed the stock mixture for preparing the gypsum concrete composite, which ensures the decrease of the specific expenditure of gypsum binding composite to 30,0% without reduction in the strength. The optimum relationship of components for preparing the gypsum concrete composite is revealed: the gypsum: ashes - 1:1, portland cement - 10 20% of the mass of gypsum. The influence of the parameters of fiber reinforcement is investigated by basaltic fibers on their properties with the application of a rotatable plan of the second order of the type of regular hexagon. It is revealed, that the maximum values of the parameters of optimization are observed in the central region of plan s i. Compression strength of the fibrogipsovermikulitobetonnogo composite increases 1,16-1,18, with the bend - 1,62-1,73 times with respect to the strength of initial matrix.
