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

10.00.00 Philological sciences
DescriptionThe article discusses the results of the pragmalinguistic experiment. Since language game is a result of speech creative work, which manifests the individuality of a linguistic personality, the politician can intentionally use language game and thereby consciously form his attractive image. The politician, who uses different kinds of language game, makes some personal characteristics building up the portrait aspect of effective political image more distinguished and thus affects the election decision of the voter. It has been studied whether language game influences such characteristics as determination, insistence, persuasiveness, emotionality, confidence, energy, sense of responsibility, dedication, trustworthiness, honesty, a certain hardness, decisiveness, autonomy, adherence to principles and assertiveness. It has been concluded that language game influences 11 of the 15 characteristics, this fact confirms the hypothesis

THE ROLE OF GAP JUNCTIONS IN THE DEVELOPMENT OF ASTROCYTIC HUMAN BRAIN TUMOR
DescriptionRecently, much attention is paid to research the role of cell-cell interactions by gap junctions in the process of malignant transformation and mechanisms of antitumor resistance. Meanwhile, the greatest interest is astrocytic tumors. Depending on the degree of malignancy, astrocytomas are divided into: pilocytic astrocytoma (Grade I), subependymal giant cell astrocytoma (Grade I), pleomorphic xanthoastrocytoma (Grade II), diffuse astrocytoma (Grade II), anaplastic astrocytoma (Grade III), glioblastoma (Grade IV ) gliomatosis cerebri (Grade IV). Information of literature devoted to astrocytic tumors (gliomas) - the most common brain tumor in large part obtained in studies in cell cultures and different contradictions. Along with data on the reduction of glial tumors cells communicability through GJ, there is evidence of an opposite character - a functionally active GJ in gliomas and inhibition of tumor growth by reducing intercellular communicability by GJ. However, up to now there have been no studies of the effect and function of hemichannels in cancer cells, which would provide detailed information on: 1) the characteristic of presence and relative abundance of hemichannels in cancer cells; 2) evaluation of absorption / release of hemichannels mediated molecules in tumor cells than in non-tumor cells; 3) functional consequences of activation and blocking of hemichannels in tumor cells and 4) the prognostic value of the expression / activation of hemichannels in human malignancies

THE ROLE OF QUANTUM ENTANGLEMENT IN TASKS OF THE GAMES THEORY
01.00.00 Physical-mathematical sciences
DescriptionThis article discusses an economic game called "The struggle for markets". We have generated a mathematical model of quantum realization of this game. For clarity, the algorithms are derived for soft and hard quantum games for assessing the impact of the degree of entanglement to work and the result of the algorithm. There are step-by-step instructions for the sequence of actions and operations to create a quantum model of the game. The aim is to assess the influence of the degree of entanglement on work algorithms. Also, we investigate the influence of quantum entanglement on the win for two or more players. The article gives a comparison with classical results

SOLUTION OF THE OPTIMIZATION PROBLEM FOR ELASTIC-DAMPING MECHANISM PARAMETERS IN PLOWING MODE
DescriptionThe article is devoted to finding of the optimum parameters for elastically damping mechanism (EDM) which is located in transmission of machine-tractor unit (MTU). The investigated MTU is based on the tractor of 1.4 class in plowing mode. EDM is designed for MTU in order to make its’ start smoothly, to reduce the dynamic load in transmission, to protect engine from the external load vibration. The “transmittance level” (index T) is used as evaluation of the protective mechanism quality. The study was carried out by means of the experiment planning method, viz. the central composition plan of second order with five factors. A regression model for response function (“transmittance level”) is given. This model takes into account the chosen EDM characteristics. The statistical analysis methods (Student’s t-test, Fisher’s test) were used to study the regression model. The dependence of response function on each factor apart, their cross impact on the process are described. The system of partial differential equations is obtained to find the optimal values of parameters and response function. The optimal value of a “transmittance level” can be obtained by varying different EDM parameter values. Optimal values of parameters and as result - response function - allow improving of MTU functioning in plowing mode
