  • Development of elements for "smart clothes" based on the electrochemical charge storage system for microsystems technique

    In this paper we propose basic geometric, mass and electrical parameters of the element for collection of static electricity from the surface of the textile. This element is a reversible electrochemical charge storage system based on nanostructured nickel oxide and carbon cloth. Element has a planar structure, it is flexible, lightweight, safety and ergonomic. Proposed element can be used as a power source for the Microsystems technique in "smart clothes".

    Keywords: "smart clothes", microsystems technique, static electricity, supercapacitor, composite material NiO/C

  • A train set forming for using artificial neural networks to database errors search

    It describes a method of train set forming for using artificial neural networks to search inauthentic rows  in databases tables. An existing methods of the reliability ensure involve the use of integrity constraints and provides a truthfulness, but there is still a possibility of entering of inauthentic data, appropriate to all constraints. A more accurate assessment of reliability is possible with the use of artificial neural networks that require a training set. The main requirement for the training set - representation includes sufficiency, diversity and evenness. The approaches to each of these requirements are describes. Also calculations a sufficient number of rows for training neural networks of various types is given, as well as the results of experiments that confirm correctness of the theoretical calculations.

  • Economic interests of big business in the conditions of a single Eurasian space

    In the context of updating the formation of a common Eurasian space is particularly important to study the problem of realization of economic interests of economic entities operating within the system of relationships. Same interests of big business, in this case, play a special role , as it is large business structures , acting as actors of economic activity, are able to set new trends in the development of the economic environment , having sufficient capacity to be able to influence decision- government authorities of administrative decisions. Formation and development of a common Eurasian economic space requires the definition of " growth points" further relations between the states to set foot on the path of integration, and that the organizational form of big business can become a support for building a new system of economic relations. Integration processes in Eurasia based not only on increasing trade between the member countries of integration, but also on their complementarities , formed naturally as a result of centuries of economic cooperation and based on the economic interests of the largest multinational corporations or associations like them , specifying the vector of development of a single economic space. In turn, this single economic space opens up new possibilities for the realization of the economic interests of economic entities , especially for major actors in national economies. This article discusses the main directions of the interests of big business, represented by transnational corporations in the new economic conditions .

    Keywords: integration, a single Eurasian space, economic interests, foreign direct investment, multinational corporations.

  • Selection of the transformation method of loess soils of Rostov region with account of different factors.

     A significant part of Rostov region and North Caucasus regions of the built-over territories according to its settlement consists of I and II type loess soil.
         The author develops a method for optimal parameters determination of the stabilized loess bases under the influence of different factors (loads, emergency steeping, ground waters level alteration etc.). Selection of optimality criteria depends on the applicable method of technical melioration. Determinative limitation is the calculation upon the II group of limit states. Application of non-linear mechanical and mathematical models for calculation of structural and unstable soils upon deformations is recommended.
         Silicification stabilizing of loess soils is almost impossible at the filtration coefficient of K<0.1 m/day.
         Characteristics of the fixed massive depend on soil moisture level, injection mode, density of sodium silicate solution, time of injection and volume of solution.
         Determinative conditions for the possibility of soils injection stabilizing with cement or other solutions are the following: geometric criterion (cement particles size and soil pores size, determined by the active openness), solution viscosity in relation to density, injection pressure, water-cement ratio, filtration coefficient. The most common pores in loess soils are active pores of 20 micron diameter, quantity of which comprises 20-50% of total soil openness. Solution-conductive (active openness) are the pores of more than 0.01 mm at size.
         Selection of stabilizing method depends on the form of the stabilized area.
         The author, basing on variation principles of mechanics of constructive and non-linear systems and theory of adaptive evolution of mechanical systems, developed determination method of rational form of the stabilized basal complex. Specific feature of the developed model is increasing of bearing capacity, stability and location of stabilizing area with more specific accuracy level within soil. To detect stress-deformed state in bases of buildings and constructions there are elaborated programs in APDL languages in the ANSYS software environment.  

    Keywords: loess soil; method for optimal parameters determimation; form of the stabilized area;theory of adaptive evolution of mechanical systems; ANSYS software environment

  • Research the relationship between technological possibility forest machines with the parameters of forest environment

      To estimate the effectiveness of forest machines developed technological possibility coefficient. Coefficients reflect the ability to provide a given performance of transport vehicles in the logging, the decline in the quality of the skid road surface. Method allows determining the amount of logging residues, necessary for the skid road construction. At calculating the available volume accounted for logging residues. Resources of logging residues are calculated depending on the type of timber and the length of skid road. The method allows selecting the optimum system of machines to work in these natural production conditions or schedule performance loss due to reduced carrying capacity of skid road.
