  • Deprivation attitude of students by Academy of architecture and building of DSTU

    The results of the pilot survey conducted in late 2016 are presented. The purpose of the measurement was identifying deprivation of students as a characteristic indicator of political tension among the youth. The cognitive component of the perception of their relative deprivation was determined by direct survey. Using the obtained results the distribution function of these parameters according respondents was constructed. In the whole group it was received a fairly low declared level of deprivation. The sub-group with low and average level is 92% and only 8% of respondents noted the high level of this indicator. Interpretation of survey data was conducted using the early developed psychosemantic phenomenological stochastic model. In the model the relationship of level of emotional perception with the received data was determined stochastic integral-differential equation. It had a Monte Carlo in the multi-agent simulation package AnyLogic. In the end, the statistical characteristics such as the distribution function for affective perception of the relative deprivation according respondents were determined. In the whole group affective component is higher than the declared cognitive one. It is suggesting the need for assessments of deprivation using not only the cognitive measure, but also affective measure. In particular, the proportion of respondents with high deprivation according to this estimation higher than that obtained by direct survey and is 12%. This part of respondents is a subgroup of the risk opportunities for the development of the protest.

  • The method of analysis of absolute stability of nonlinear impulse-systems through a computer-based approach innors

    Abstract: The analysis of absolute stability is reduced to solving the problem of the distribution of the roots of a real polynomial with respect to the unit circle.Televisions recurrent expressions for by the computer to determine the coefficients for a system of arbitrary order. The machine is a technique for solving the problem of the distribution of the roots of the polynomial by computing determinants innorov and counting the number of sign changes in the ranks of the special values innornyh determinants whose elements are uniquely associated with the parameters of the system under study. To calculate determinants of matrices of values can be reduced to a triangular form, using the Gaussian elimination algorithm. However, a special kind of matrix (the presence of the left triangle of zeros) provides extremely effective double triangulyarizatsii algorithm that allows to determine the values innorov by computers with minimal cost.

  • Simulation modeling as a tool for integrated assessment of strategic risks logistics companies

    The possibility of improving the management efficiency of the main business processes of a logistics enterprise on the basis of an integrated assessment of strategic risks is considered. The methodology is based on the idea of sharing the technology of simulation and two concepts: the Balanced Scorecard (BSС) and the Integrated Risk Management System (IRMS). We propose formula for calculating operational risk based on port statistics collected while running the simulation model, namely the chosen values of the triangular distribution of the statistical data. Also presented a formula linguistic evaluation of integrated strategic risk, lead to the conclusion the risk that previously designated port strategy will not be achieved.

  • Option trading strategies efficiency analysis for MOEX assets with a machine learning approach.

    An inportant and challenging task for a market analyst is to predict a value or a direction of a certain indicator based on the behaviour of a given financial instrument. In this paper we use random forest algorithms to predict a value and a direction of an implied volatility of RTS index options. We collect and prepare the historical data with an algorithm which takes into account both the actual trades history and the ordlog. We then examine and use the effect of volatility clustering which can be observed on such options. Finally, we construct some simple option trading strategies based on the predictions we made and measure their performance on a subset of our historical data. The results obtained shows that such approach can of use as one of the mechanisms for making decisions in practical trading, and needs further research.

  • Affective components of attitudes of students in relation to the intrapersonal conflicts Part I

    The article discusses research methodology of intrapersonal conflict by using the affective component of appropriate social attitudes. We analyze three kinds of internal contradictions. Which are classified by K. Levin as the conflict of ""Desire-Commitment"", ""Avoidance-Avoidance"" and ""Commitment-Avoidance"". They are all connected with a choice of appropriate object or action (equal or different valences) of the two equally probable. The affective component of perception of such internal contradictions is determined by the technology of semantic differential on the basis of the survey conducted at the end of 2016 among students DSTU. For the interpretation of the results used the previously developed technique. The distribution functions of the emotional perception of those conflicts are described in article. Which were calculated as in the linear approximation and a nonlinear lookup psychosemantic model. It is obtained that the average affective perception of the studied conflicts neutral or close to that. But the researched audience is very heterogeneous in its emotional attitude to such conflicts. The distribution function is strongly smeared almost all over the range of levels of perception. While approximately half of the respondents are characterized by positive attitude to internal contradictions. This suggests that positive role of conflicts associated with the resolution of problems of an appropriate level subconsciously affects on estimates. A few unexpected results were obtained by a comparison of the perception of conflicts ""the Desire-the Desire"" and ""Avoidance-Avoidance"". Distribution function for the problem of the choice of two positive options is being shifted to the left, in the negative direction, compared with the function for a choice of two unattractive possibilities. The work has shown the promising use of such figure as the affective perception for researching of intrapersonal conflict. The obtained results possess as General methodical so purely situational, specific significances.

  • The improvement of preparative processes during the earthworks on the linear main pipeline portion

    The article proposes a special device which enables to improve the preparative processes during the main pipeline break at any technique of general maintenance or trench breaking. The device has been made to fix characteristic points on the surface of the earth. The application will enable to exclude the use of stakes or pegs driven into the ground. The device allows to continuously mark the space without stopping the machine to apply a special mix. The use of the marking on portions of pipeline bends will enable to cut the volume of the ground extracted from the trench and therefore to reduce the length of stripping. The application of the device will allow to improve the preparative processes prior to stripping works. The use of the proposed device will give the opportunity of its application in all the climatic conditions nationwide.

  • For calculation the reinforced concrete columns with mixed reinforcement

    Effective use of high-strength reinforcement in concrete structures - an important task today. Studies of Russian and foreign scientists have shown that the most expedient are combination of prestressed and untensioned reinforcement in section. When designing the compressed concrete elements with prestressed reinforcement should strive to reduce the amount of pre-tension reinforcement in columns, on the contrary, to increase the pre-compressed in short elements. In elements with pre-compressed steel, untensioned reinforcement is needed, because it provides improving crack resistance during transmission technology process tensile stresses on the concrete and untensioned reinforcement. The percentage of this reinforcement should be the minimum necessary to achieve the required cracking resistance. Minimal amount of pre-tension reinforcement adopted at the level of prestressing (usually the highest) should be taken of the conditions provide the desired crack resistance and rigidness. Later in the article describes main principles the calculation minimum number of prestressed reinforcement in reinforced concrete elements to the presentation requirements of the first, second and third categories crack resistance.
