  • Physicomechanical processes of loading at a driving tunnels depending on characteristics of material

    In article the factors defining efficiency of roadheader technology application of transport tunnels construction are considered. As one of the factors containing growth of carrying out speed of tunnels is the loading part of the combine, in article the analysis of the factors influencing efficiency is made. Stochastic process of interaction with the destroyed mountain weight is considered. The analysis of the developed approaches to determination of executive body loadings productivity with loading paws with a destroyed mountain weightstack is made. Influence of a form of the immersed material particles and geometrical ratios of loading body and average fineness of material particles is analysed. It is revealed that extent of influence of a particles form doesn't exceed the statistical errors arising at research of loading process of lump mountain weight, and geometrical ratios have significant effect on loadings and productivity. When determining loadings it is offered to apply model taking into account linear proportions coefficient, and it is necessary to apply the model considering influence of active volume on formation of system output characteristics to calculation of loading part productivity. Taking into account influence of the described factors, the calculated value of productivity and loadings increases in comparison with the generalized models that confirms expediency of use of the described dependences.

  • Determination of degree of homogenization of composition mixtures based on estimation of entropy of optoleptical information obtained by mixture surface photosensitive scanning

    In this article we consider technique of determination of degree of homogeneity of heterogeneous mixtures by using tool contactless method. This method uses optoleptical information of mixture surface. This method can be used in automatic control systems. An optoleptical information may be obtained using standard devices of photosensitive scanning. The value of entropy of otptoleptical information is used to estimate the degree of mixture homogenization. Operations of component mixing are widely used in technological processes. The degree of homogenization of mixture is the one of quality indicators of mixing process. The degree of homogenization is usually determined by laboratory method, which requires additional time for analysis. The degree of homogenization can also be determined by using the senses. In this case, the results of determination depends on the experience of the expert. In this article we looked at an example for the paint industry. The method can be applied to a wide range of heterogeneous composition.

  • A multi-dimensional model of social attitudes for the politically active part of the Rostov region population

    The technique of the multidimensional analysis of socio-political attitudes is shown on a concrete example. The results of questioning which was carried out in the spring of 2014 among the Rostov region population participating in the work of election commissions of the lower level are the basis for work. In total 144 persons were surveyed. On gender and age distribution, and also on socio-economic indexes our sample was typical for the above mentioned population. About 29 characteristics were used as input parameters in model. They were levels of affective and cognitive perception of the local and central authorities, cognitive estimates by respondents of the relation to various parties of socio-political life, the characteristic of a social portrait of respondents. The affective components were determined by technology of semantic differential, with the subsequent calculation within nonlinear approach. All cognitive components were computed by results of direct poll. Entrance sizes were unwrapped a multidimensional cube on a platform of a package of the multidimensional analysis by IBM Cognos. The functions of respondent’s distribution were computed both for separate components, and for various sections of a cube at the exit of model. The analysis for social and economic, national, confessional, territorial, gender profiles is carried out. It was discovered, in particular, the essential peculiarities in the territorial plan for the main leading factors of a conflictogenity (an affective component of political attitudes). Hierarchy of factors of social tension was created It is shown that the presented technique allows to conduct comprehensive investigation of a socio-political condition of any audience.
