Receiving adequate mathematical model requires studying of streams of inquiries into the information system which are described as random variables. The purpose of the analysis is definition of density function of distribution of random variables - time intervals between inquiries of users. The offered method contains stages at which check of independence and similarity of distribution of random variables is carried out, stationarities of a stream and the law of distribution of intervals of time between events is defined. For check of independence and similarity of distribution of random variables the criterias based on selective coefficients of correlation and the criteria which are based on the spectral density of intervals are used. For the analysis of stationarity of a stream of inquiries the standard methods of the smallest square regression and methods based on the analysis of special mathematical models are used. For example, Poisson's stream which parameter changes under some law is supposed. Sequences of the events displaced by casual influences are presented as the events happening according to the schedule with delays in the form of the independent and equally distributed random variables. For comparison of intensity of streams of inquiries from various users of information system the criterion based on the relation of function of maximum similarity and an index of dispersion is used. The offered technique is focused on using of the modern computer programs, for example, MatLab, Statistika.

It is shown that one of the most important elements influencing the nature of development in the region is socio-ethno-cultural landscape. The study of its characteristics suggests a wide use of methods of social simulation. The purpose of modeling is to estimate the required parameters in conditions of uncertainty, both at the planning stage and during the current administration. Theoretical solutions to this challenge are based on the use of the principle of duality, when the production and analysis of missing information about a managed object, in our case about socio-ethno-cultural landscape, the system is in the process of governance. The duality of the models appears in their dual role as research (for monitoring characteristics of socio-ethno-cultural landscape and, at the same time as the reference models for the management of development in the region. Need of approbation and problem integration of methods of the system analysis, social diagnostics and social and mathematical modeling which will make new scientific methodology of research is shown. To solve the problem of this level is proposed for effective convergence of methodological knowledge in the use of total potential informational, cognitive, and socio-humanitarian technologies.

The article examines the impact of particulate reinforcement modified basalt microfiber (MBM) on the strength properties of cement mortars. Unlike conventional particulate reinforcement fibers reinforcement solutions modified microfibers based on the assumption that the introduction of such mortar mixture nanomodified dispersion-reinforcing fillers leads to an increase in the composition of the cement stone elongated structures extending for hundreds of micrometers, which leads to a corresponding hardening solutions based on these nanoadditives. Thus, there is a dynamic dispersed reinforcement cement stone. As the nano-additive authors used a modified basalt microfibre (MBM). The effect of MBM on the strength properties and mobility of mortars of various compositions with equal water-cement ratio: control (without additives and MBM) with MBM, with the addition of superplasticizer and with the addition of superplasticizer and MBM. Also, studies were conducted on a cement-sand mortar of normal consistency with the addition of MBM and superplasticizer. As a result of entering into the mass of the modified artificial stone microfiber obtained with improved strength properties (flexural strength and compressive strength), indicating the feasibility of introducing such microfibers in mortar mixes. However, significantly reduced mobility mixtures which requires the introduction of the plasticizer.

in modern conditions become widespread trenchless methods for the construction of pipelines. The positive features of their use include increased speed pipeline installation, reducing the volume of excavation, etc. Existing regulatory documents limit the bending of the pipe at low temperatures need to be tested in terms of their applicability to new grades of polyethylene. The aim of this study was to determine the minimum permissible bending radius of the track, the passage of which in the conditions of negative temperatures polyethylene pipes PE80 would maintain its strength characteristics. By using a mathematical model dependency of the elastic modulus and yield point are calculated from the temperature stresses in the walls of pipes of different diameters in bending under different temperatures. In order to establish empirical relationships voltage on the pipe diameter and the radius of its bend procedure is carried out function approximation method of least squares. Presented obtained graphic dependences. Using the values ​​of the yield strength of the material at different temperatures were calculated bending radius of all dimensions. If the production of the track plow trenchless pipe-layer will be considered given the conditions, you will be provided with the necessary conditions for installation.
