Description
In this article, the special classification of logging machines and technologies of carrying out cleaning cutting is considered. The mathematical model of quantity of the damaged trees, remaining after cleaning cutting in coniferous plantings is described. The decision of optimization problem of quantity of damaged trees and productivity of logging machines at cleaning cutting is submitted. Possible decrease of quantity of damaged trees is shown, due to use of the automated choice of system of logging machines

AUTOMATIC CONTROL SYSTEM OF CHARACTERISTICS OF DEVICES OF MOVING ON THE AIR PILLOW
DescriptionMethods of jet pneumoautomatics with reference to devices of moving on an air pillow are considered. The local system constructed on the basis of methods of jet pneumoautomatics, for management of thickness of an air pillow is shown. In clause the opportunity of automatic removal of dusty air from a working zone of pneumotransport system is reflected. On the basis of hydro dynamical calculation parities for engineering calculations of values of

ANALYSIS OF METHODS OF GENERATION OF TIME SERIES WITH LONG-TERM CORRELATION STRUCTURE
01.00.00 Physical-mathematical sciences
DescriptionThis article gives a comparative analysis of six modeling techniques of fractal differential noise, including: direct definition method, the method of Hosking, the method of Davis and Hart's, the circulant embedding method, Paxson method and method of spectral simulation. Furthermore, the algorithms are given for the analysis and the method of estimation of Hurst`s parameter is selected, this method is the main criterion of quality when comparing the above mentioned methods of fractal differential noise

ANALYSIS OF DEVELOPING LEVEL OF THE AGRICULTURAL SECTOR IN KRASNODAR REGION
DescriptionEconomic development occurs throughout the life of society. The economies of various countries differ from each other by different sets of parameters, but primarily by the method of creating and maintaining the infrastructure, the way the state's participation in economic relations. Agriculture has been and remains one of the most important sectors of the economy. Therefore, the question of support and development of the industry will always be relevant. Western and central Europe are paying great attention to this matter: developing programs to support agricultural producers, apply stimulating tax system, creates favorable conditions for export. In Russia, the level of agricultural support is growing, but still lags behind European standards
