  • Simulation of the design activity diversification of innovative enterprise

    The main target of sales policy in a competitive environment is customer funnel and customer loyalty. Sales approach involves encouragement of customers, vendors and business partners. Advertising is a means of a sales activity. While determining the most efficient way of distributing expenses for the purpose of advertising, it makes economic sense to use mathematical methods of programming and statistic analysis of target audience. It is able during the analysis to determine the most efficient time and location for ad placement, possible target audience and its income level. A method of calculating should be selected in order to gain more profit and incur less expenses. This is Fore and Malgrange method which allows to do so. Benefit of this method is optimality test in the process of decision making.

  • Analysis methods of the Russian financial market volatility for a wide class of models

    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.

  • Stability of previously compressed reinforcement in concrete beams

    Preliminary tensile steel bars, stacked in the tension zone of reinforced concrete structures, allows significant savings. Research carried out in recent decades, many scientists in the Russian Federation and abroad, show that the reinforcement in the compressed zone, subjected to preliminary compression, and is able to give a significant economic impact. This question has not been investigated. There is no justification for such a common attachment to the transverse reinforcement, especially when you consider that they work only in the short period of hardening concrete (28 days). It may be that there are extra expenses expensive metal, time and labor. These reasons impel to consider in order to create a mathematical model of this problem from the standpoint of structural mechanics and its decision.

  • Features of qualitative and quantitative composition of emissions in the production of building materials

    The article is devoted to the peculiarities of qualitative and quantitative composition of emissions in the production of building materials. This article describes a way of reducing dust emissions of solid substances pollutions exhausted in the atmosphere in the manufacture construction materials. The article focuses on the environmental problems of building construction industry. Volume of production of building materials is growing up and amount of dust particles substances in emissions around 5-8% every year at least both. One of ways to increase the environmental safety is reduction of dust emissions. Data on the relative content of some types of dust, typical for the construction industry in the total dust emissions entering the atmosphere of the city enterprises. The results of studies show that a significant content of fine particles, for example, 10 microns or less is concern in dust emissions systems of aspiration at the building construction enterprises. The great amount mention above of solid substances fine particles dimension involves the usage of special complex integrated analysis method of variance dust. The great amount mention above of solid substances fine particles dimension involves the usage of special complex integrated analysis method of variance dust. The value of the maximum permissible concentration of fine particles content by mention above dimension (around 10 microns) is less than for ordinary powder of building materials’ dusts. There exist and work a lot of building materials enterprises treat with bulk building materials in present time. It isn’t necessary to have ecological project of limitation emissions for small construction companies. So that this reason demands the improvement norms methodology for limitation for fine particles are concern in dust emissions systems of aspiration at the building construction industry. It allows preventing growing pollutions of atmosphere by emissions with fine particles dust.
