In the article the author examines factors and reasons causing the problem of strengthening the power asymmetry as a result of market expansion of trading networks, which is identified by the author as a system empirical trend in the market determining structurization of its organizational field.
Evaluating the high potential of development of format trade in the Russian market, the author concludes that the rapid expansion of trading networks creates enormous pressure on the manufacturing business: increasing potential difference is transforming into asymmetry of market power of network retail trade and production companies that stimulates the process of their extremely non-equilibrium strategic positioning in the system of goods supply in the domestic market of the country.
The author comes to the conclusion that the potential of building mutually beneficial strategic partnership relations between manufacturers and trading networks is today relatively restricted by reason of dominant position of networks in the system of goods circulation in the consumer market. Formation of economically effective and strategically balanced partnership alliance of networks and suppliers occurs predominantly only with medium-sized and large manufacturing FMCG companies which have sufficient level of technological capacity and resources which allow them to produce quality high-tech production adequate positioning of which automatically creates in the market powerful production brand.

The simulation of two-dimensional spherical crystals consisting of a large number of particles is carried out. These shells were analyzed based on their geometric structure and energy distribution. Various types of defects formed in a state of equilibrium  is considered. Being shown the ambiguity of the existing method of their interpretation. A new way of describing such defects in the close-packed two-dimensional crystals with different topology is suggested.

The paper studies the possibility of quantitative processing of the GPR data for determining the dielectric permittivity and conductivity of a medium (soil samples). Experimental studies are made using radargrams of soil samples with specified values of moisture and conductivity. New methods of quantitative processing of radargrams are proposed in this work to determine the dielectric permittivity and conductivity of soils. The methods were successfully tested on various sections of Russian railways net.

Tendencies of technological improvement of electronic chips led to reduction of their sizes, weight, development of functionality and decrease in power consumption. It allows us to discuss questions of developing renewable micro power sources which can provide power supply of autonomous microelectronic and micro circuitry systems for charge indication, paying attention to snow transfer, etc. 
The purpose of the paper is researching a profile of electrostatic field potential in the mountain district which was estimated as a possible use as a renewable micro power source.
It is found out that on windward sides of snow relieves the potential of electrostatic field exceeds three times to a similar  indicator for lee sides and is 80 V.  The potential is 3,5kV on polymeric surfaces (Nylon, teflon).   

Keywords: snow storming electricity, electrization, potential of electrostatic field, charge, the salting, the loaded particles of snow, innovation electronics, micro circuitry, renewable micro power sources.

The results of computational experiments to determine the characteristics of the porous piezoelectric ceramics based on the methodology, including the effective modules method, simulations of representative volumes on a simple random method and the method of Witten-Sander, finite element method to solve static piezoelectric problems for heterogeneous composite media and the accounting of inhomogeneous polarization near the pores are presented. A comparison of the results of computer simulation with the known experimental data for the porous material PZT-4 and its analogs is realized. It is concluded that the accounting of inhomogeneous polarization in the vicinity of porous provide the better agreement between numerical results and large number of known experimental data. Thus, for most effective constants the smallest errors are obtained for a representative volume of the porous piezoelectric material, constructed by Witten-Sander method.

The simulation of the process of the electrically active impurities relocation in the electric field of Schottky diode space charge region has been made. The analysis of the simulation results shows the possibility of controlled alloying impurities relocation on the depth about tens of nanometers caused by electrically active atoms diffusion in the electric field of Schottky diode space charge region.

The coloration centres (CC) in crystals of rear earth gallium garnets (REGG): Gd3Ga5O12 (GGG), Gd3Sc1,6Ga3,4O12 (GSGG) и Nd3Ga5O12 (NGG) obtained by Chohraljskiy method, were investigated by methods of optical spectroscopy and spectral analysis in the wavelength range of 0,2-0,87 microns. In the case of keeping the samples under dark conditions, unstable CC were formed in the crystals of GGG and GSGG. The absorption maxima are at λmax1 = 0,243 m and λmax2 = 0,275 m at concentration of N ~ 1018 cm-3. It is suggested that the observed enlightenment is caused by the recharging of growth defects and occurring the energy levels in the band gap of garnets. It appears that these CC correspond to centres of O- holes, originated from gallium vacancies V3-Ga 3+ in tetrahedral and octahedral nots which form near clusters of [V3-Ga 3+ - V2+O2- ]

Is devoted to the actual problem of constructing classifiers objects given by a point in a multidimensional space of feature values. The principle of linear normal classification of objects in multi-dimensional space of attributes can be used to build a classifier in the case of many complex structures, in general, are inseparable one hyperplane. In such cases, proposed to use a set of hierarchically related normal separating hyperplanes, which is called the normal hierarchical classifier.

The authors identified the contradictions economic substantiation of development projects of territorial development and socio- environmental factors, the adverse effects of their realization, on the basis of which concluded the need for modernization of the basic principles of risk management for sustainable development of urban territories . The article proposes a set of principles that are required for the formation of an effective system of risk management of investment and construction projects of development of urban territories, which includes five interrelated principles : the principle of the matter of feasibility activity, the principle of optimization of protection, the principle of an integrated estimation of the danger, the principle of ecosystem sustainability, the principle of "the polluter pays". The proposed principles will gain the efficiency of the analysis and selection of projects for realization only able to provide the highest level of security and stability of the socio- economic sector of the city.
