One of the most important elements of the bridge, from which the service life of this structure directly depends, is the supporting part. It provides the movement and rotation of span structures, as well as the transfer of all loads from the forces acting on them to the supports. The task of the designer is to select such support parts, that could be allowed maximum reducing of the forces, acting at the ends of the beams and having a minimum resistance to their free movement. It is necessary in each case to select the support part, which will most closely meet the requirements. To solve this problem, the author structured and tabulated the kinds of support parts. And also an analysis of the main characteristics of some of them.

This article discusses some of the problems arising in the study of political processes of network modeling methods. The relation of concepts, models and their practical application in the analysis of political events is analyzed. The purpose of work is to examine the hypothesis testing problem in the practice of political analysis using empirical methods in the field of cooperation between public institutions and networks of civic engagement structures. It is shown that the use of network modeling methods to move from descriptive methods, cluster analysis to statistical models, reproducing the interaction of political subjects, which makes it possible to produce test of hypotheses by empirical methods. Statistical models combine the methods of qualitative analysis and quantitative methods of hypotheses verification and application of the results of various concepts in political practice. Revealed the limitations of the use of the research capacity of the network models, associated with incomplete empirical data obtained during the field research that requires the experiments, various forms of observation and interviews. Results of the analysis and forecasting can be used in the practice of "network management", aimed at the impact on the network structure by changing the institutional rules and regulations.

The article presents the results of approximating of ion current signal of the most appropriate parametrical models in Matlab software. It is shown that in spite of the high accuracy of approximation, parametrical model Gaussian, which chosen early in Matlab, have significant drawbacks. In order to eliminate the identified deficiencies authors was developed parametric model in which the discrete Fourier transform was used to approximate of the ion current signal.

Keywords: ion current, the internal combustion engine, a parametric model, a discrete Fourier transform, the Gaussian model, the approximation of a signal

The article considers a problem of the Russian financial market modeling and suggests wide classes of diffusion and jump models. The authors examine the adequacy of the diffusion models by means of quadratic variation analysis on the Russian financial market, which is used to construct the volatility index, the most important quantitative risk indicator in the financial market. It is shown that the existing volatility indexes RTSVX and RVI worse approximate the realized variation than the alternative index, based on the implied variation integration. Further analysis of power variation of log-returns for RTS index shows that Levy processes with unbounded variation without diffusion component better describe the dynamics of the Russian financial market. A new model-free formula for the volatility index is proposed in the class of Lévy processes. The new formula suggested is based on the variation representation via market option prices.

Keywords: mathematical modeling, numerical method, mathematical finance, volatility index, option, Levy process, diffusion model, quadratic variation, RTS index, derivatives market.

Abstract: We consider the importance of taxation instruments on sustainable forest management. The goal is the creation of geographic information systems to efficiently develop leased forest areas in the short and long term to meet the requirements of the forest legislation of the Russian Federation and the minimization of the cost of a unit of harvested timber, in order to increase profits logging companies.

Problem of the choice of software testing method as a problem of a multicriteria optimization is put and considered in this article. The method of testing of the separate program module can be automated, manual or the mixed. In this case the problem of optimization has a degenerate representation because the set of admissible decisions contains only several elements Such formal simplicity is compensated by the significant amount of criteria and a graduated algorithm of their calculation. This algorithm is based on processing of expert estimates. Estimates are given in group of programmers – creators of the software product, and in group of systemic testers. For programmers the special questionnaire is used. The algorithm of the solution of an optimization problem based on a method of group linear convolution is offered. Total value of convolution for the separate program module corresponds to one of three possible methods of testing: automated, manual or the mixed. The offered algorithm can be extended to other problems of discrete optimization with terminating quantity of elements of an admissible set.

Keywords: software testing, multicriteria optimization, admissible set, automated, manual or the mixed testing, expert estimates, program module, linear convolution, algorithm of the solution of an optimization problem
