MANAGEMENT, COMPUTER FACILITIES AND INFORMATICS

113-119 354
Abstract
In article are presented theoretical and experimental studies of the motion grain material on sieve the system cleaning of the combine harvester with dynamic leveling. The comparison of the theoretical and experimental studies is made.
120-126 362
Abstract
This article introduces a computer program EOSupport (Experimental Optimization Support) written by the author which helps to design experiments, process experimental data, calculate regression coefficients and compute statistical criterias for testing experimental results. The article also contains results of two successfully solved with EOSupport typical optimization problems.

Abstract
The problem of finding maximal flow in networks with barrier reachability is considered. It is shown that existing algorithm for solution this problem can't find solution for all networks. New algorithm is suggested.

ENGINEERING AND AGRO-INDUSTRIAL SPECIALTIES

137-140 254
Abstract
Outcomes examinations with an estimation effect of damp on the basic indexes of process separation grain lots in the pneumocanal of the machine prestress clearing (MPS) of a grain material are reduced.
141-144 261
Abstract
The article gives the analysis of possible criteria of application when accounting vibratory parameters mobile agricultural machines optimization. The example is given.
145-156 220
Abstract
The axiomatic description of a considered problem is made. Stages of formalization of indistinct expert knowledge are considered.

MECHANICAL ENGINEERING

157-167 266
Abstract
In work results of theoretical calculation of basic elements of the closed technological package for coating composite coverings are brought.
165-169 295
Abstract
In the presented work on the basis of Reynolds's equation the method of final elements solves a problem about distribution of pressure in lubricant film. Influence of rotation on distribution of pressure and on bearing ability of the bearing is investigated. Comparisons of key parameters with theoretical and experimental data of other authors are lead

Abstract
Results of unseat moment investigations for metal-polymeric turning pairs are cited. Testing machine and testing technique are described. Fluent features of thermal and power load conditions to friction coefficient are descripted.
177-186 320
Abstract
It is given to the method calculation of wear resistance of WC, phase Laves, superstructure and composite materials on their basis. Received results are discussed.
187-191 260
Abstract
In the given work with purpose of geometry restoration and hardening of the form-building tools without removing from the machine tool considered the opportunity of protective wear resistance coatings production using discrete ELAC technology (electro-acoustic coating).
192-196 282
Abstract
Nano level technologies for wear resistance increase were considered for Different materials: cemented carbides, high speed steels and polymer composites.
197-202 253
Abstract
The study of the karbotitanosianirovanie process in multycompounds melt salts, in radio-frequency electromagnetic field was considered. At was shown the possibility of checking of "diligences" melt salts by means of acoustic emission experimental method.

Abstract

A quantum chemical study of the structure and stability of such antifreeze components as water and glycol has been undertaken using ab initio method in DZV basis. It is shown, that if ratio of water and glycol is optimal, decreasing of temperature leads to self-organization in the molecular level and structuring of water- spirit mixture and conversion to the solid state in low temperature (-75 оС).
