DescriptionThe experiment considered the influence of different methods of agricultural technologies on the yield of winter barley in the dependence of the investigated factors. The studies were carried out at the experimental station of Kuban State Agrarian University in the conditions of multifactorial longterm soil monitoring. The experiment was carried out in a typical 11-field grain-grass-tillage crop rotation with the following alternation of crops: alfalfa, alfalfa, winter wheat, winter barley, sugar beet, winter wheat, corn for grain, winter wheat, sunflower, winter wheat, spring barley with sowing of alfalfa. Stationary experience is represented by the following factors: the level of fertility (factor A); fertilizer system (factor B); plant protection system (factor C) and methods of basic soil cultivation (factor D). The relationship between the influence of the soil fertility level, fertilizer norms, plant protection products, the soil cultivation system and yield, and the crop structure of the perspective winter barley variety ‘Gordey’ were determined. The soil is chernozem leached superheavy light-clay with an average thickness of the humus horizon - 150 cm. It is found that fertilizer, soil treatment, seeding method; protective means increase the yield of winter barley and positively influences the elements of the yield structure. The yield increase in comparison with the control changed from 10.4 to 26.8 c / ha. The statistical processing data show that the fertilizer system (35.8%) and soil cultivation (27%) had a certain influence on the number of productive stems; the fertilizer system (44.6%) influenced the spike size, the fertilizer system (28%) and the tillage (32.8%) had influence on the amount of grain in the spike and influenced the mass of grain from the spike

SEMANTIC SEARCH ENGINE BASED ON ONTOLOGY MAPPING
DescriptionWe live in a world of rapidly developing information technologies, where many organizations are related to each other, forming complex information networks. Therefore, storage, analysis and retrieval of information is a very complex and urgent task. In connection with the advent of search engines and communications, millions of people are engaged in the search and retrieval of information. Commercial search engines, such as Google, use keyword search based on logical queries. The main disadvantage of this search is that it returns a lot of irrelevant information, which leads to low accuracy. In this article, we focus on building a semantic search system based on the mapping of the ontological model. This includes various stages of development of ontology, the phase of indexing and information retrieval

Description
Now in different branches of the industry there is a need for the new equipment and mechanisms with the seized characteristics. Special requirements are shown to energetic and mass-dimensional indices of systems of electric drives as one of the main components of such devices. Mass-dimensional and energetic indices due to constructional features and the used management system will allow improving use of special or controlled asynchronous cascade systems of an electric actuator of cylindrical construction. One of the main difficulties is simulation and design of special systems of the electric drive. In this article, a new approach to determination of magnetic model parameters of the stator of a component of the controlled asynchronous cascade electrical drive of cylindrical construction is offered

Description
The work is done in scientific and practical directions for minimization of power losses in transmission of electricity to local distribution networks between the actors of the energy (producers and consumers) of energy-saving technologies focused on technological activities such as modernization and reconstruction of networks. Quite often in various circuits of power systems, it is advisable to transfer energy and its power through intermediate (transit) nodes. Structural changes in the electricity sector, at present, are mainly associated with the introduction of market relations between the subjects of energy exchange; therefore, in this work special attention is paid to the problem of calculating the power losses, as it is nonlinearly dependent on the power at the nodes and branches of a network. It should be noted that the nodes in problems transit capacity could be both sources and consumers. The latter necessitated the need for search of possible ways to reduce transportation losses of energy due to both the improvement and optimization of distribution networks and through the use of intermediate transit nodes. It follows that the transportation problem in this formulation is more General and expands the possibilities of optimization of power losses for the local subsystems of the energy clusters. The work is composed of the transport matrix for solving problems transit capacity, where the algorithm taking into account the distinctive features of which consist in the use of continuous numbering of sources and consumers in the matrix, and any node can be a transit country. The transit capacity ii-th node Zii=0, and the dimension of the matrix in contrast to the previously considered tasks has (n+m) (n+m) and it remains square as all the transport problems of linear programming. Transit variables Xii are included in the solution of the problem with a minus sign, and all transit variables are considered basic. From the above example in the work of a number of branches of a network is minimal, which significantly reduces the cost of building and maintaining the network, and the solver minimizes the power loss between the subjects of energy exchange and, as a result to savings from the standpoint of cost of construction of the network and the management of overflows of energy in it

Description
Considering the pluralistic nature of the process of interpreting modern theorists of individual elements of economic reality, the main purpose of this article manifests the need to clarify the integrity and uniformity of approach to objective reflection of the realities of the economy. The basis for study in this work selected the category is "cost-permanent", an example of which is shown differentiation theoretical-economists views, that in the opinion of the author makes it difficult to harmonize the interpretations of the economic system, and therefore the subject of the article is of particular relevance. To prove the existence of a dichotomy of views within the scientific article analyzes the general population sources of theories about the nature of persistence fixed costs and based on exploitation mathematical and statistical apparatus disclosed each side of the existing concepts. Assuming that high-quality and reliable information on the level of management activities - the key to making competent and reasonable management decisions, according to the analysis to overcome the distortion of the generated objectification developed an integrated approach to understanding the category of fixed costs. The integral approach is argued by the admissibility of the existence of several points of view and the possibility of reducing them to one, which is the scientific novelty of the work

Description
Most of the tasks of planning and organizing transport routes are pointed to solving optimization problems on graphs in multi-criteria statements, for which the only optimal solution is missing. In conditions of multicriteria, it becomes necessary to search for a set of alternatives instead of an optimum. The quality of the admissible solutions is estimated by the vector objective function. The article proposes to investigate the problem using a special class of graphs - prefractal graphs, which allow describing in a natural way the structure of the hierarchy of territorial links, as well as enable to take into account structural dynamics in terms of system growth. A multicriteria mathematical formulation of the problem of covering a prefractal graph by simple intersecting chains is constructed, to which the investigated problem of organizing routes in large-scale transport networks reduces. The main social and economic requirements for the transport system are formulated and included in the model in the form of criteria

EFFICIENCY OF THE FERTILIZER SYSTEM IN THE TECHNOLOGY OF EMPOWERMENT OF WINTER WHEAT
06.00.00 Agricultural sciences
DescriptionWinter wheat is very demanding on the nutrient regime of the soil. Like many winter crops, it consumes the nutrients unevenly distributed during the vegetation period, which must be considered when making them. Modern varieties of winter wheat are very demanding to soil fertility. For the formation of 4,0-4,5 t/ha requires about 140 kg of nitrogen, 50 kg phosphorus and 120 kg potassium. Therefore, without the use of fertilizers, it is not possible to obtain such a crop with high grain quality. In addition, in the cultivation of winter wheat in the high and intensive technologies simply need using large amounts of fertilizer to compensate for the removal of nutrients. This is especially important when having partial or complete reduction of application of organic fertilizers. Therefore, we consider the possibility and the results of studies using different doses, combinations and types of fertilizers in technology of winter wheat cultivation. Experimental studies were carried out in the conditions of insufficient and unstable moistening of southern zone of Rostov region, on experimental fields of the federal state scientific institution «ASС «Donskoy». For research, we have chosen the most common varieties of winter wheat (Tanais, Granite, Axinite, Terra, Donskoy prostor, Motto) and various combinations and combinations of mineral and organic fertilizers. The experiments were conducted on two predecessors: couples and peas. As the controllable parameters we had the productivity and quality of winter wheat. We have found a positive impact of the in-change of fertilizer on the studied parameters with a share of the variance of 96% and a high degree of correlation of 0,98. The marked increase in the productivity of winter wheat is up to 22% when using different versions of the experiment. We have identified rational combination doses of mineral and organic nutrition for predecessors: peas N40P60K40+2N30 and vapor – manure 40t/ha+2Р60+2N30
