Abstract

In the previous papers for the integral Fredgholm equation of the first kind with a degenerate kernel the generalized (non regularizing) version of the projection method was developed, based on the arbitrary choice of the basis combined with some a priori estimations for the error of the solution. These estimations depend on the residual which was neglected earlier. The results of the present paper admit to take the residual into account and show that, generally speaking, this accounting is essential.

MECHANICS

Abstract

The article proposes a new method of modeling the evolutional system, which interacts with the environment. The cutting process or tribo-space, which are formed in the contact area of two conjugate mechanical subsystems, are considered as an environment. The features of the environment depend not on the coordinates of the state of the system, but on the trajectories. That is why the parameters of the environment are performed not as integral operators of the equations like Volter equation.

Abstract

Three-dimensional acerbity and its determination. The notion three-dimensional acerbity element of the hydraulic system is Offered. Happen to the got analytical way of the formula for determination brought three-dimensional acerbity different element hydraulic system, as well as formula for determination brought three-dimensional acerbity of the free number hydraulic element, comprised of system parallel.

MANUFACTURING ENGINEERING

208-211 272
Abstract

The outcomes of rational design of semiproducts in process of die forging for the forging of the hemispherical shape are submitted. The approach is realized by a boundary-element solution of a sequence of inverse tasks of metal flow when filling the die cavity on algorithm reverse loading. The obtained solution allows to realize a flawless die forging process at the minimum accepted size of a burr.

INFORMATION TECHNOLOGY, COMPUTER SCIENCE AND MANAGEMENT

212-217 460
Abstract

In the article the method of accuracy increasing of manufacturing details on the technological equipment by means of additional signal formation for keeping up drives depending on movement parameters of working body is considered. The structure of the adaptive neural network focused on problems of keeping up drives control is offered.

FRICTION AND WEAR

218-223 288
Abstract

The work analyses the dependence of hard-alloyed materials contacts surfaces adhesive bond on yield limit of various steels.

Some quantative values of adhesive forces, adhesive coefficients and adhesive bond strength used for phenomena evaluation as well as for approximate calculations are reached.

224-227 329
Abstract

Wear resistant criterion suggested for choice of the fused surfacing hard alloys for hard usage. The criterion investigation is advisable for composition of hard alloys selection. The increase of wear resistance achieved by means of simultaneous enlargement of hard inclusions content and bending ultimate strength with constant of friction and defect size lessening.

ECONOMIC SCIENCES

228-235 261
Abstract

In this article, the areas of existence of the major financial parameters and the types of dependences appropriate to them are revealed. Ordering of financial parameters as dependences has allowed to reveal leading parameters wich can be used for definition of an orientation of development of the enterprise from all set.

Abstract

Organization of production is one of the directions of STP (Scientific Technological Progress). It place an important role in increase in enterprise efficiency. The application of new technologies is not always effective at the low level of organization. The increase in enterprise efficiency depends on organization of manufacturing processes.

It can be achieved by the effective application of modern equipment, rational use of materials, energy, tools and labour resources. The purpose of developing organization of production is the improvement of economical results. That is why, determining the level of organization it is necessary to appreciate its in flounce on on economic indices.

Abstract

The brief characteristic and a technique of realization of the analysis and improvement of administrative and industrial business business-processes are given in the article. The offered approach and a technique of realization of research of business-processes allow to develop information systems at the enterprises and organizations with a minimum quantity of mistakes. The information on realization of the analysis of process of service parts in Open Society SOTT “Rosneft-Krasnodarneftegaz” is presented in the article.

255-261 257
Abstract

The paper considers technological structure of the economy as a factor of the country’s absorptive capacity. The work is based upon the statistical analysis of the main developed countries. The author reveals a regularity, which connects the structure of the interindustrial linkages with its capacity to adopt foreign technologies, firstly from the foreign direct investment. The model is based upon the newest theoretical works in organizational learning theory and interindustrial linkages. The results can be applied by investigations of international technological diffusion, as well as by arranging the priority directions of attracting foreign direct investment.

PHILOSOPHICAL SCIENCES

Abstract

This article shows a main point, reasons of social conflicts and methods of controlling them for decreasing of social tension in the society and  realization of an election campaign.

CONCISE INFORMATION

270-275 251
Abstract

The analysis of Nd-Fe-B based alloy crushing products grain size distribution was used to investigate the peculiarities of alloy crushing process in the impact mill at various electromagnetic field parameters. The correlation of constant and variable magnetic field induction and variable magnetic field induction gradient, providing the effective crushing and homogeneity of crushing product sizes was obtained.

Abstract

The changes of organization have a different directions depending to company activities.

This text is about restructuring as a basic stage of business processes development. To create the flexible, ready-and-able for changes organization we should understand the transformations necessity, then develop the restructuring scheme, after that revitalize organization to create it as open system and renew working up with the spirit of organization (see figure).

279-283 233
Abstract

The production technology of the quality control, it’s strategy and planning in the process planning with the ability of aid with the computer is the important component of the improvement of the quality  stability of the production according to the set of standardsPN-EN29000. The review and the essence of works, which are carrying out in this field in the Division of Process Planning and Technological Design Systems were described.
