TRIBOTECHNICAL CHARACTERISTICS OF TUGSTEN DICHALCOGENIDES REINFORCED POLYHETEROARYLENE PM-DADPHE MATRIX COMPOSITE COATINGS UNDER SLIDING FRICTION IN LIQUID LUBRICANTS

Abstract

The paper presents the method of parametric synthesis of aerial-feeder radio receiving and demodulating facilities based on new backbone factor - equivalent energy losses for parametric devices which provides the balanced synthesis of major system parameters that are consistent with upper limit of invested assets and development trends in telecommunications networks. The relevance of the article is due to the fact that at present time there is a close and fairly complex relationship between electrical, mechanical, technological, technical and economic indicators for the synthesis of aerial-feeder (AF), radio receiving (RR) and demodulating (DM) facilities, which involves the application of a systematic approach and modern methods for solving multivariate optimization problems. As a rule, the objectives of this class are resolved by methods of linear and nonlinear programming. In this case the partial equivalent energy losses of the nodes constituting the AF, RR and DM facilities are related to their costs. The lower demands for partial equivalent energy losses, the higher the price of achieving them. The ammount of partial partial equivalent energy losses for AF facilities forms a vector of partial equivalent energy losses. The vector of price cost corresponds to the vector of AF facilities parameters. In this case, the problem of aerial-feeder devices is to solve the problem of mathematical programming, i.e. the task of finding the conditional optimum.
