Uniqueness estimation technique of the electronic geographical chart's fragments is considered. The technique uses uniqueness of the mean square deviation of mapping contours of objects on a chart as а description of thechart's fragment uniqueness. The mean square deviation is calculated on the basis of the classical linear regression. Feasibility of using additional characteristics for the estimation of uniqueness of electronic chart's fragments is shown. It is offered an approach to the uniqueness estimation of the electronic chart's fragments based on an application of a fuzzy linear regression with an asymmetrical triangular accessory function, which provides an execution of more exact differentiation of electronic chart's fragments by means of introduction of additional characteristics of uniqueness. The mapping technique of unique electronic chart's fragments is offered. The mapping technique uses fuzzy measures of similarity of objects contours on the chart.

A methodology for automating the production of wired communication cables using advanced process control (APC-systems) based on predictive models to ensure the required quality of the cable as a communication channel based on its bandwidth is proposed.

The synthesis of a control system for a third-order unstable object is discussed. A method for structural construction of an unstable-object control system is offered. Regulator transfer functions to ensure high speed are found.

The results of analyzing the error of realization of a measuring method for harmonious signals integrated characteristics which is caused by the quantization of signals instant values are discussed.

On the basis of practical experience and analysis of the publications the ways to improve the plating quality are given.

The paper compares the methods of direct and reverse impact testing of internal anti-corrosion coatings of oil and gas pipes and makes a conclusion on the applicability of the reverse-impact method for the quality evaluation of pipes with internal anti-corrosion coatings.

The efficiency problem засева extensive territories of the Russian Federation and zones with any is superficial-geological specificity large forests and other kinds of plants is investigated. The purpose of the developed method - fast economic restoration of green weight. The aviation method of disembarkation of woods and other plants by capsules of a seed material by dump from an aviation board manually or with application of pyrotechnic cartridges without presence of the person and technics on the earth is developed. The method organisation is developed. The design of the pyrotechnic cartridge from non-polluting materials is offered. Aerodynamic forms of seed capsules are developed.

The problem of cylindrical specimen surface layer stress-strain state evaluation after surface plastic hardening and following heating is investigated. It is shown, that due to Young’s modulus change during the temperature stressing essential residual stress fields change happens. Results for cylindrical specimens, strengthened under different technologies, are introduced.

The vertical scheme of assembly of cylindrical details, during which one of them is fixed, and the other one moves, leaned on the edge of the other one, was analyzed. The fundamental laws of their matching were established. The trajectories and the velocities of the points located on the moving detail surface were determined. The equations of the centrodes rigidly connected to the details were obtained. The method of the calculation of the minimal assembling forces was proposed. The method of calculations of the range of minimal values of the forces both assembling and preventing from the assembling the details was proposed.

This paper was supported by the Ministry of Education of the Russian Federation (state contract 14.516.11.0111 from 14.10.2013 y.).It describes the foreign operating experience and design features of amorphous magnetic circuit transformers. The feasibility of their use in the distribution networks of the Russian Federation is stated. The results of the simulations to replace traditional transformers with amorphous-steel cor transformers are presented. The necessity to improve overvoltage protection by means of surge arresters is pointed out.

Thepaper is devoted to comparison of mass and heat exchange properties of different convective surfaces. Flue pipes and spiked surfaces are considered. Convective heat transfer of these surfaces is shown.

Coefficients of gas rate for burners type AGG-2, AGG-3 and AGG-4 are determined by experimental data. It allows to calculate dynamic parameters for these burners during designing of fuel burning systems.

We discuss a simple algorithm for evaluating the characteristics of a stationary stochastic process with exponential correlation function which does not require solving a system of nonlinear equations.

The paper deals with the detonation of fill-up and water-filled industrial cyclonite. The critical diameter and pressure for the initiation of industrial cyclonite detonation have been determined. It is shown that these parameters are almost identical to those of crystallized RDX, a slight change in sensibility being due to air inclusions in the RDX grains .

The solution describes the methods of synthesis the communicating mobile robot capable to memorize and restore configuration on the plane. Configuration sets the coordinates of the robots. Population of robots dynamics sets nonlinear differential equations in complex numbers. Achieved design and physical parameter modeling system of mobile robots with ultrasonic navigation system that implements the connection between the individual robots and obtained preliminary estimates using such a navigation system for the synthesis of mobile robots with multiple memory configurations.

This paper presents a systematic approach to syntesis of starting pressure shifts, based on experimental data.
