Photoconversion efficiency of light into electrical current is limited by recombination, thermal and other losses of photon energy in the structures of solar cells, including those used in space vehicles. The equations describing the loss, adjusted the light dispersal ohmic losses in the surface layer. For the first time an assessment of the heat losses due to Peltier effect at the contacts of the circuit of solar cells. The ways to minimize recombination losses in the surface layer due to the electric field of contact charges are discussed.

An algorithm is presented for a manipulating robot (MR) control in an unknown static environment. A theorem is proved stating that following the algorithm the MR in a finite number of steps will either reach a target configuration or come to the proved conclusion that the target configuration may not be reached. Given sequences from the theorem facilitating the MR functioning in the unknown environment.

We have considered a random access communication network with conflicts of requests, which mean that the arriving request and request under service are sent to a retrial pool. For a process of system states changing the embedded Markov chain is built up. The theorem on non-ergodicity of Markov chain, which proves the instability of functioning of the computer communication network managed by a random multiple access, is formulated.

The technique of synthesis of modal regulators of coordinates of vector system the converter of frequencyasynchronous engine is resulted by a method of the standard equations. The estimation of quality of processes of regulation of coordinates by the analysis of results of simulation modeling of the system in the environment of MatLab is given.

Intelligent information technology automated design for solving complex problem of data analysis and decision support is considered in this paper. Evolutionary algorithms are applied for generating connectionist models, fuzzy systems and neuro-fuzzy systems. Genetic programming technique application for intelligent information technologies kollektives design is proposed for system effectiveness and reliability improvement.

This paper addresses the pricing of correlation-dependent credit derivatives. We first examine the one-factor Gaussian copula model that has become the market standard. Then we present a new approach to model parametrically a dependence structure. Our approach is based on using a multiplicative approximation. Eventually, we use a numerical example to compare these models.

For determining of limitary deformations for planar constructions reinforced with curvelinear trajectories the resolving equations are obtained for orthotropic non-homogeneous linear elasticity problem. A variety of orthogonal systems - oriented reinforcement structures is obtained by isogonal trajectories designing for current coordinate lines.

The article presents results of researches of the influence of modes of gas feeding to a cavity of a discharge chamber on the basis critical parameters and characteristics of electrojet engines. Increase of operating effect of electroget engines is reached at the expense of, first, additional distribution of gas on depth of the discharge chamber by placing ports of injection of gas directly to an input in an ionization zone, and, secondly, by orientation of ports of injection of gas so that submitted gas mainly moved along an input in an ionization zone. Tests were spent on models of a various standard size in a range of working capacities from 100 Vt to 2,3 kw, including modes of operation at high discharge voltage.

Based on the representations of the flow pattern of the working fluid in the channels of the disc with blades, we calculated the main parameters of the «liquid-gas», with proven experimental data.

The article presents one of the embodiments of adaptive antennas, allowing effectively suppress interference in a given direction, while maintaining the basic signal.

Original technology of sequential processing of satellite data presented with picture patterns of chlorophyll distribution in the surface layer in the global ocean and sea surface temperature is considered in the article. This technology has been developed at Institute of biophysics, SB RAS. Analysis of challenges for thematic processing software developing is discussed. A brief description of preliminary stage is given. SeaWiFS, MODIS and NOAA picture images were used as input data.

The article presents experimental and numerical analysis results of induced stress-strain state in the process of manufacturing of a piece of composite material.

Influence of impurity atoms (Al, B, C, Ge, P) on rate of diffusion of lithium in crystal silicon is investigated by DFT calculations. For that potential barrier values for lithium atom passage between potential minimum nearby impurity atom have been calculated. It is shown the presence of Al or Ge atoms near lithium atom decreases the potential barrier value at 0,02-0,07 eV, but the presence of C or B atoms increases the barrier value at 0,14-0,17 eV. And the presence of P atoms does not influence on the potential barrier value. The calculated lithium diffusion rates show that injection of Al or Ge atoms into silicon increase the lithium diffusion rate at ~4 times at 300 K.

Possibilities and prospects of technology rotational sharpen external screw surfaces of details of cars compulsorily rotated multifluted are shown by the tool.

The theoretical approachs to the determination of concept of intellectual potential of enterprise is summerised. The place and the role of intellectual potential in the system of the intellectual provision of enterprise are defined in this article.

The analysis of the definitions of the concepts of «technical upgrading», «retooling», «modernization», defined by their similarities and differences. Proposes a number of empirical criteria to characterize the substantive content and direction of implementation of the above activities when used in a process the company.

Application of state-private partnership in the Russian Federation as the tool, allowing to consider interests of all participants of economy is considered: societies, business-structures and the states. It is offered to carry out stateprivate partnership through leasing, as the most comprehensible form of economic attitudes.

This investigation is addressed to appraisal of scientific preparation commercialization prospect. As the theoretical base the branchs technological trajectory conception is used. It explains the connection between branchs peculiarity and innovation behavior. The systematization of existent innovative developments is suggested, the analysis of their basic characteristics is conducted. The derived opportunities of innovative development are correlated with regional industrial enterprises readiness to accept these developments.

In article the innovative potential as one of major factors of competitiveness of a higher educational institution is considered. Concepts «competitiveness» and «innovative potential of high school» are given. The problem urgency is proved, factors of competitiveness of high school are allocated. Groups of indicators for an estimation of level of innovative potential of high school are revealed.

The author proposes to analyze and evaluate the economic security, based on the potential economic security. This potential is considered to be a result of transformation of quantitative characteristics to qualitative performance of an enterprise, along with interdependence of external and internal transactions in this process. Transactional approach is used within the boundaries of the functional analysis of cash flows.

In the article the author proves the urgency of assistance in employment of graduates of vocational training establishments. Classification of services which carry out this process and basic elements are presented.

This paper compares the fundamental postulates of neoclassic paradigm and Keynesian model with the modern capitalism. It shows that neoclassic paradigm, which underlies economic structure of major countries, is inadequate to the essence of market economy. The research concludes that the current crisis in the countries with both advanced and developing market economy has happened because their economic structures, each on its own way, have ignored the requirement of the systematic government regulation due to basing on neoclassic paradigm. Keynes model, which in fact has never been implemented, may be a base for a revised holistic, stable, and robust economic structure - for a new capitalism.
