CAPACITY OPTIMIZATION ON THE IRRIGATION TECHNICS
Description
Mathematical modeling of process of an operational parameters choice of watering techniques, which can be used as the theoretical basis, allowing making multiple numerical experiments for the purpose of results reception for a concrete irrigated site, is considered. Article is recommended for researching and other organizations at designing new and reconstruction of existing sites, and for the operational organizations at decision-making of a choice of technology and watering techniques

AREAS OF ECONOMIC APPLICATIONS OF VECTOR DYADIC RISK MODEL
Description
The heuristic find of the dyadic vector risk model construction is checked by its practical applications in economy on a number of test examples. These are the calculations of resulting risks of optional length logistical chains of projects or local risks charged events, a case of risk insurance, calculation of a composite vector of “risky cost” by risky event result

06.00.00 Agricultural sciences
Description
The method and results of forecasting of crops of agricultural crops in the Rostov region on reclamated lands are resulted. The method is based on use of dependence of crops of agricultural crops from agro meteorological factors. Results of calculation on planning crops of winter wheat at irrigation are shown

01.00.00 Physical-mathematical sciences
Description
In the article general mathematical expression for a quantitative assessment of system (synergetic) effect, arising when integrating buleans (systems), being a generalization of sets in system generalization of the theory of varieties and independent of an expedient (algorithm) of formation of subsystems in system is offered. For this quantitative standard the name is offered: «Generalized coefficient of emergence by R.Hartli» because of likeness of its mathematical shape to the local coefficient of emergence of Hartli, reflecting a degree of difference of system from the variety of its base devices. For local coefficient of emergence of Hartli, the generalization independent of an expedient (algorithm) of formation of subsystems in system is offered. Numerical estimates of system's effect are given at integrating of two systems with ap-plication of the author's program to which the refer-ence is given

LABORATORY MODELLING OF FILLING PILE
Description
The grounds of modeling of filling pile static resistance have been offered so as the results of its realization at the laboratory models. The laboratory testing data are compared with the data of field testing of natural piles. The experimental and the model calculated values of bearing capacity shows the correlation coef-ficient 0,692. The laboratory tests confirm the exis-tence of the local maximum of the settlement “accele-ration”. The point of maximum proposed separates two stages of bearing capacity increment process: the stage of lateral surface mainly resistance and the stage of pile bottom mainly resistance

Description
An approach to the valuation technique of decorative signs Syrian Hibiscus (Hibiscus syriacus L.) is suggested. A scale consisting of 15 characters is developed. Each attribute in this scale is evaluated and indexed by the coefficient of the importance of this trait afterwards. General guidance of the evaluation of each decorative feature is given
