  • The Optimality principles in stydying of the social and economic labor market processes

    Labour market is a complicated social and economic system, which requires the necessity to consider a number of characteristic properties (stochasticity,nonlinearity,inertance,nonstationarity) for investigation and modelling labor market processes and phenomena. In this article the problem of optimum control of a labour market is mathematically formalized. This allows for regional system of a labor market to reach desirable indicators, namely the set unemployment rate.

    Keywords: Labor market, optimum control, optimizing tasks, principle of a maximum of Pontryagin, social and economic system

  • Мobile training complex network infrastructure

Described training complex designed for loading/unloading machine operators training.  The variant of the solution that satisfies the requirements is proposed.  The work was supported by the Russian Ministry of Education (contract № 13.G25.31.0093) as part of the RF Government Regulation № 218 "On measures of state support for the development of cooperation of Russian higher education institutions and organizations implementing complex projects on high-tech production"  

    Keywords: Computer training complex, architecture, control, crane

  • Comparison of the results of a calculation of the astronomical refraction near the horizon in different ways

    Performed calculations of angles of the astronomical refraction in different ways and made a comparative analysis of the results of a calculation. Provides recommendations for the use of any means in different contexts.

    Keywords: Astronomical refraction, the Hour angle, Anti-aircraft distance, atmosphere, Pulkovo table.

  • Astronomical Refraction anomalies and their accounting

    When performing measurements anti-aircraft distances of celestial bodies must take into account not only the corners of the astronomical refraction, but also its anomalies. The method of accounting for refraction based on observations of heavenly bodies near the horizon.

    Keywords: Astronomical refraction, Anti-aircraft distance, atmosphere, Refractive errors, Azimuth

  • To a question of a choice of protection of building designs at the enterprises with excited environments

    The question on the scientifically-grounded choice of protection of building designs at the enterprises with excited environments which mechanism on materials of designs is insufficiently investigated is considered. (aggressive technological environments of the medical enterprises)

    Keywords: Corrosion destructions, building designs, excited environments, protection against corrosion

  • Features of the development and implementation of wireless terminals for crane operator training complex

    The article is devoted steps for the development technical support for crane operator training complex. An important component of technical support is a wireless terminals. Formulated a list of requirements for a wireless terminals: correct operation of the program crane simulator, reliability, compactness, wired and wireless communications to PC, flexible configuration, self-diagnostics, low price. Mobile Remote includes  terminals and host. The host is connected to PC via USB interface, as USB HID device. Terminals transmits the information to a host by Bluetooth. Selected hardware base for the terminals and host (microcontrollers, wireless modules, batteries) and designed printed circuit boards. Investigations of the different batteries and the battery life time of terminals. The description of the design decisions, especially this development.

    Keywords: Computer simulator, wireless terminals, microcontroller, battery, USB HID device

  • Construction lending covenant

    Construction lending risks define a special operations procedure for lender. The most important measure to construction lending risk minimization are the covenants (information and financial). The information covenants are used for minimization the hidden information (pre-contractual opportunism), and financial covenants (positive and negative) – for minimization the hidden action (post-contractual opportunism). Institutionalization of covenants as a relevant control and supervision procedure allow to reduce information asymmetry and make the construction lending process less risky and more predictable for concerned parties (agent and principal).

  • Simulation of the design activity diversification of innovative enterprise

    In work the scheme of regulation of a dynamic level of a liquid which can be used in systems of oil extracting with the purpose of increase of efficiency of their work is offered. The scheme of a regulator of the level consisting of proportional and integrated discrete elements that has allowed to reduce a static mistake is described and on the basis of to raise efficiency of regulation of a dynamic level. Modelling process of work of the offered scheme of regulation is lead, results are analysed and recommendations on parameters of a regulator are developed. Procedure of use of the offered scheme also for the control of a degree not fillings the pump is described.

    Keywords: The scheme of regulation of a dynamic level of a liquid, is proportional-integrated regulator of a level, regulation of a dynamic level of a liquid in a chink, not filling the pump.

  • Development of the new method for determination of 3D nano atomic and electronic structure of materials based on XAFS, XRD and Raman techniques

    Combined method which allows analyzing parameters of the nanoscale atomic and electronic structure of materials relying on three different methods (x-ray absorption spectroscopy (XAFS), x-ray diffraction (XRD) and Raman spectroscopy) was developed. The method was applied for the study of nickel oxide nanoparticles, which serve as an efficient catalyst for the artificial photosynthesis process.

  • Operando dynamics of the nanoscale atomic and electronic structure of materials for hydrogen storage

    We have carried out the analysis on the scientific and technological literature on methods of calculation and analysis of the x-ray diffraction, x-ray absorption and Raman spectra used to analyse the structure of the materials for hydrogen storage under realistic operating conditions. The simulations were carried out for the series of small palladium nanoclusters with embedded hydrogen. Multiscale computer modelling was used to simulate the dynamics of structure of the materials during charge/discharge phases.
