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.

A widespread technology with deep litter floor with broilers. Promising material for bedding are the straw materials. However, straw, held a simple reduction, does not meet the zootechnical requirements, in particular the recommended length of the cut should be 50 mm to 150 mm. Thus, there arises the problem of fractionation straw, obtained at harvest crops as waste. We carried out an analysis of the different types of fractional chopped straw with nodal connections without them. Studies have been conducted on the behavior of these types in an air classifier with a velocity change .

Keywords: The straw residues fractionation aerodinomicheskie performance, fly speed

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 short review of existing panoramic systems are given. The limits of such systems doesn't allow to form a panoramic video with dealing the parallax effect in real-time systems. The presented algorithm for forming a panoramic video is free of these disadvantages. An algorithm based on mathematical model of the round-view system that takes into account the location of cameras, their intrinsic parameters and model of the world. The algorithm includes following chain of coordinate transformation: from panoramic image coordinates to spherical coordinates and to Cartesian world coordinate system, from world coordinates to camera coordinate system and to input image coordinates. Geometric distortion of camera is dealt. Model of the world is represented as spherical and a hemispherical surfaces.

Keywords: panoramic image, round-view video system, camera model, camera distortion, parallax

Only innovative activity is able to unite all aspects of science, equipment, economy, business and management. The current state of the innovative sphere of Russia speaks about serious contradictions in its functioning. Considerable scientific and technical capacity of the country was lost in the period of economic reforms. Now often it is impossible to predict precisely succession of events in economic life of the country generally and each organization separately. In modern conditions scientific and technical progress represents innovative development which is defined by the state as the most important priority of economic policy. Innovative potential of any managing subject needs to be estimated as difficult social and institutional system. To encourage managers and the production personnel competently developed motivational strategy is necessary to conduct work on search of innovations. Achievement of the put indicators of innovative development of the Rostov region and the country as a whole has to become result of an offered method of interaction of science, business and authorities.
