A method of ultrasonic sensors calculation is considered. The mathematical modeling of ultrasonic sensor for high-temperature products scanning is offered. The additional recommendations for microprocessor system formation for high-temperature products scanning are given.

The value of software for the designing processes of space technique units, its improving problems at the present moment level are considered. The recommendations how to solve these problems are given.

The methodical approach to lifetime estimation of machines details at percussive-cyclic loading is offered. The realization is based on sharing the corrected linear hypothesis of tireless damages accumulation and schematization the irregular transitional loading processes methods, calculated by the finite elements method

The effectiveness estimation method of zero-current switching quasi-resonant converter in comparison with classic PWM converter is proposed

The highly effective numerical algorithm is developed and tested. It allows to solve a wide class of bidimentional non-stationary problems. Mathematical modeling of the non-stationary processes proceeding in the channel linear MHD - the accelerator is lead. In full statement the bidimentional problem of magnetic hydrodynamics in view of effect of the Hall is solved. In the result of modeling the deviation current effect of a layer from a direction, perpendicular to electrodes of the accelerator is found out. The results are will qualitatively coordinated with experimental data.

The opportunity of the diacoptics method application for the algorithms reliability of the various software and managing systems research is considered. The value of this method is extremely actual now in connection with a sharp increase in complexity of algorithms structures and considerable financial expenses for the software development

The technique of the reliability research of N-version software is offered. It allows using algorithms and methods of network analysis for the reliability research of software, developed by N-version approach using.

The tensor method for probability-time characteristics analysis in content delivery network is considered. The comparative analysis of results of the tensor method and simulation in GPSS is carried.

A modified mathematic model of GERT-network is presented, where the condition of setting constant numeric value to the probability of arc changed to the condition of computability of the probability after arc initial node activation. Also the constraints for availability of computer evaluation of network are considered

The properties of quasi crystal material structure are described. The term «quasi crystal» is defined. The application area and synthesis method of quasi crystal structure is given. The plasma spaying synthesis method is the most perspective one.

The synthesis of water-soluble polyhydroxylated fullerenes using mixtures containing fullerenes and iron particles as precursors in considered. The iron nanoparticles are shown to catalyze fullerene hydroxylation process. It allows to realized hydrolysis in water and thus to avoid undesirable application of sodium hydroxide as the source of the hydroxyl groups, which causes the fullerenol agglomeration

A research method for thermal-oxidative stability of motor oils under testing temperature cycling, evaluation criteria for the testing temperature effects on the oxidation processes and the oxidation product on the oil viscosity are represented

Based on foreign experience the complex of organizational and methodological offers for the improvement of managing and crediting system of innovation industries is presented

Motivation and management personnel with system management quality are examined

The possibility of application of the polarized development and innovations diffusion theories in their interrelation in the region with the rarefied economic space is investigated.

The realization of a national priorial project in the sphere area of public health service demands a serious approach. All the activities must increase the functioning efficiency of the system itself. The investigation of public health service development factors and conditions allows to reveal working balances of the efficiency growth both tendencies and regularities occuring this system and influence of these tendencies and regularities on the social-economical development of regions.

The institutional environment and its factors for small-scale business are analyzed. The author made practical approaches to the mechanism of municipal and regional policy of the small-scale business maintenance and development, taking into consideration both foreign and domestic experience. The author also elaborates tools for business maintenance and development

The fundamental and applied problems connected with formation and realization of steady innovative policy are considered. Thus the choice of the innovation efficiency estimation and successful realization of innovation development of the enterprises of power engineering are defined according to specific goals and problems of innovation policy.

The necessity to develop silicon industry in the Russian Federation is well found. The features oft of the silicon industry in the Russian Federation development are examined and systematized: the main enterprises working in this field and the projects supposed to be implemented, the home market features. Each project existed in the RF silicon industry is estimated with the relation to the future trends, weak and strong aspects are released, much promising and viable projects are determined. Possible ways to develop silicon industry in the Russian Federation are indicated

The basic tasks of logistic management at a management freight motor-car transportation control using information technologies are examined. The comparison of the existed satellite navigation systems is brought

The necessity of resource-saving technologies penetration with the purpose of economic efficiency of grain manufacturing increase in Krasnoyarsk region is proved.

Conceptual model of investment priorities estimation is offered. It provides the analysis carrying out either at regional and branch focus or micro level. The model combines some methods of economical and mathematical modeling including cluster analysis and many-dimensional regression analysis. Estimating priorities or micro level it is recommended to use fundamentals and methodical tools of real options conception
