Description
Our research aims at providing new effective control methods for scientific and technical expertise to organizations and foundations that fund research projects on a competitive basis. These methods should provide analytical decision support for group decision making in a distributed environment. In this work, we consider an integral model for knowledge representation – a socio-semantic knowledge network that combines social links and a semantic description of knowledge into a mathematically formalized graph theoretic structure. In terms of actor-network theory, we consider a multimodal network with actors on one of the levels and artefacts (i.e. contexts that express network links) on the other level. In order to represent knowledge domain based on a graph and hypergraph paradigm and fuzzy sets theory, we provide a sufficiently complete set of elements and relations (either trustworthy or partially trustworthy) both between multitype elements and their heterogeneous groups. The formal representation allows applying the model to solve numerous practical tasks such as expert finding, formation of expert groups, expertise refinement, reduction of subjectivity, analysis of an expertise process, analysis of processes within expert groups. Research methodology: social network analysis (SNA), theory of graphs and hypergraphs, fuzzy calculus and fuzzy logic

LOW HEAD IRRIGATION PROJECTS OF WATERING VEGETABLE AND FRUIT GROPS
DescriptionIn this article, the analysis of the developed local irrigation system with the simultaneous nutrient application is given. On the basis of the experimental data, the author pointed out that to solve the problem, the process design ensuring sufficient application of nutrients for growing vegetable and fruit crops is required. The fertilizer and water mixing device according to the Patent #2448450 is considered

NEW CONCEPT OF FORMATION OF VEHICLES RECYCLING
DescriptionNowadays, in Russia there is a problem of utilization of vehicles. The article has studied the various works proposed in the concept of creating "horizontal" system recycling vehicles. We have offered a different, "vertical" system concept, consisting of three subsystems, which together form a single waste management system

A NEW MATHEMATICAL MODEL FOR OPTIMIZING FRACTURE LENGTH IN THE IRANIAN OIL SAND RESERVOIR
DescriptionCreation of hydraulic fracturing in the physical structure of the reservoir rock is one important way to improve the productivity of oil and gas wells. These artificial channels increase ability of the reservoir rock for conducting hydrocarbons to the wellbore. In this study a new approach has been proposed for optimization of fracture half length in hydraulic fracturing operation. Also, this new method that is a combination of various fracturing geometry models has been proposed for modeling the hydraulic fracturing geometry. We have shown that there is a reasonable agreement between the result of pseudo 3D fracture geometry model and the predicted results from the proposed approach

NEW DESIGNS OF COLUMNS, INHABITED, INDUSTRIAL AND ADMINISTRATIVE BUILDINGS
DescriptionOriginal screw designs of buildings and columns are offered. Frameworks of these buildings and columns are the bearing elements and means of external and internal decoration of buildings and constructions. Originality of such buildings and columns frameworks is ensured by the fact that their design is decorated on the outer surface with broken or smooth screw edges and screw surfaces. Versatility of the offered screw columns trunks designs, as well as the possibility of performance of their left or right screwing allows reaching certain symmetry or their repeatability in the form of harmonious alternation of the bearing trunks of screw columns and spaces between them. Giving to numerous sides of trunks of screw columns of a certain invoice, or their coloring in different colors, will contribute even more to their expressiveness and beauty. Durability and vibration resistance (including seismic) of such trunks of screw columns at the same volumes of construction materials, in comparison with round and rectangular trunks is higher

NEW SCIENTOMETRIC INDICATORS RESISTANT TO ARTIFICIAL “IMPROVEMENT”
DescriptionThe article presents the new criteria suitable for the diagnosis of the productivity of research and the importance of its results for the scientific community, are resistant to artificially "improve". It is known that generally accepted measure of the productivity of research scientists is the h-index, which is calculated based on a statistical method of scree. This indicator is applicable to research teams (organizations). However, the h-index and a number of other scientometric indicators based on citation, are easy to be artificially increased (fraudulent schemes action). New scientometric parameters adequately reflecting the importance of research results, and not amenable (or very difficult to) to be artificially "improved" are therefore needed; moreover, it is recognized around the world: the true score (not fictitious) of the significance of the results of a research scientist for the scientific community - is a complex metrological (scientometric) task. The authors argued that such indicators are primarily index latitude demand for research results, as well as a number of other parameters of copyright. Despite the fact that authors indicators, the same as the h-index are based on citation, their large values indicate that the scientific community recognizes the results of the research activities of scientific and pedagogical workers; moreover, these indicators can be considered as a criterion to identify really promising (productive) researchers. The problem of adequate assessment of the productivity of research activities and the significance of its results, the authors consider in the context of the problems (larger problems) of the effectiveness of educational environments. The practical significance of research results lies in the possibility of their use for constructing criteriondiagnostic apparatus for monitoring research activities of scientific institutions (including higher educational institutions). Research methodology: systemic, metasystemic, probabilistic-statistical and qualitative approaches. Research methods: cognitive, structural, functional, and mathematical modeling; methods of graph theory, sets and relations; system-cognitive analysis; methods of quality control (theory of latent variables); methods of probability theory and mathematical statistics (first of all – a method of scree), methods of analytical geometry; methods of the mathematical theory of limits
