Nowadays the wide integration of automation resources is occurred in many domains of industry. One of the key aspects of this process is control automation for breaking up process on railways. Due to the fact that main element of railway yard is hump the Intellectualization of decision making processes becomes the key task in area of fault prediction during breaking up. The experience of fault effects elimination shows this task decision allows to reduce the financial and time costs for breaking up process. This paper proposes new algorithm for creation of theoretical base of the system for fault prediction. This algorithm is realized by hybrid methods, which combine different temporal models characterizing technological process of sorting of following cuts.

The results of theoretical analysis of literary data about the media-centrism and the socio-centrism as approaches to consideration of opportunities of mass media as the instrument of public opinion management are presented in the first part of this article . The substantiality of the media centrists approach is explained. The insufficiently proved aspects of the socio-centrism are revealed. Conclusions of the theoretical analysis are given as argument of relevance of empirical research. Studying of efficiency of the Russian mass media as a factor of public opinion formation became the purpose of empirical research. Its results are considered in the second part of this publication. The collecting of the source data was carried out by the method of sociological poll. The respondents were interrogated about the rather preferred mass media, news telecasts, and also their representations about the more discussable events. The comparative analysis revealed the considerable similarity between positions of public opinion and character of the information patterns broadcast by the preferred TV channels.

The work contains the approximation of the third boundary value problem of schemes of high order. The approximation of the operator of the convective and diffusive transport difference schem were obtained, which has the fourth-order approximation error. The discrete operator diffusive transport in the absence of the influence of the boundary was considered.The construction of schemes of higher order accuracy approximates the operator diffusive transport in the border nodes in the case of boundary conditions of the third kind with the second order of accuracy was found.

The manuscript traced the impact of changes in the content of alkaline-earth elements on the dielectric spectra of solid solutions based on lead titanate. Two concentration areas with sharply differing nature of the manifestations of dispersion phenomena were identified. First (0.02≤α1≤0.24) is characterized by strong dispersion ε/ε0 in all temperature range and not allow to generate maximum of ε/ε0 for Curie temperature at low frequencies, the second (0.24≤α1≤0.36) - a sharp decrease of Δε in the ferroelectric phase and complete disappearance of it in the solid solutions, SS, with α1 = 0.36, indicating stabilization of the structure with the introduction of alkaline SS elements. It was found that as increased the concentration of modifiers in the compositions there is a stabilization of their structure with a gradual decrease in the phase transition temperature. Formation of two concentration areas where changes macro properties SS is undoubtedly a consequence of their correlation with the phase diagram of the studied SS, which is experiencing a transformation in the neighborhood of α1 ~ 0.24, due to the transition from two-phase to single-phase state. The results obtained by the authors can be used in the development of high-temperature (α1 0.24 ) anisotropic ferroelectric materials.

In this paper, the concept of chromatic set of fuzzy temporal graph is introduced. Chromatic set of fuzzy temporal graph is a generalization of one side of a fuzzy, but on the other hand - temporal graphs. The degree of connectivity vertices changes in discrete time in a fuzzy temporal graph. Most of isomorphic transformations of fuzzy temporal graph change their external representation without changing its signature. In this regard, matters relating to the consideration of temporal invariants of fuzzy graphs. Example of finding chromatic sets of fuzzy temporal graph is considered here.
