The research results can be used both in scientific sphere and for making investment decisions in the practice of players of the Ukrainian market.

Methods and Means of Knowledge Elicitation in Chinese Image Medicine for Achieving the Tasks of Its Ontological Modeling

Abstract: The substantiation of a complex of methods and means of knowledge elicitation in Chinese Image Medicine (CIM) for the tasks of its ontological modeling in addition to the development of intellectualized information systems is the topical issue of the article. The methods of specific knowledge elicitation from the CIM experts has been defined in the research, the templates of questionnaires for a group survey have been developed as well, the axiomatic-deductive strategy of the structural and logical organization of the acquired knowledge has been used, according to this data a fragment of the diagnostic ontology of the CIM has been implemented.

Organization of the Content of Academic Discipline in the Field of Information Technologies Using Ontological Approach

Abstract: The paper presents strategy for organizing the content of the academic discipline using an ontological approach, which enables an effective system solution of a range of important methodological, methodical and technological tasks for the development of intellectualized systems of electronic education in the field of information technologies. The mathematical structures that describe and detail the abstract logic-semantic core of the discipline in the form of a set of axiomatic systems are developed. It is shown that the ontological approach of the organization of educational content ensures the presence of a clear, compact, ordered structure of the knowledge organization about the subject area of the academic discipline and is well consistent with the theoretical formal basis for the development of modern ontologies - a family of descriptive logics. As an example of the application of the proposed approach, the elements of the glossary and taxonomies of the concepts of the discipline “Computer Logic” are developed.

Influence of Preliminary Deformation on Micromechanisms of Failure of Offshore Gas Pipeline Material

Abstract: The S and J - methods of pipe laying tend to increase the brittle fracture component in the material, however, they have practically no effect on the residual life-time of metal under low amplitude cyclic loading (260 MPa). An increase in the stress range up to 320 MPa enhances the negative effect of preloading, which is more pronounced in case of using the S - method of pipe laying as compared to the J - one. Within the high amplitude range (420 MPa) the process of preliminary deformation causes the activation of relaxation processes and longitudinal splitting in the material, giving rise to an abnormal increase in the cyclic life of the plastically deformed material.

Investigation of the structural model of adapted machine for harvesting root crops

Abstract: Place your method development of deterministic mathematical models that describe the intensification of the process of separation of impurities heap root crops combined working bodies of transport and technological systems to adapt the machine for harvesting root crops. Based on the application of the transformation equations are obtained Laplasa transfer function in the operator form, which describe the functional processes of work of adapted the machine. A method is resulted developments of the determined mathematical models, which describe intensification of process of separation of admixtures from to the lots of root crops by the combined workings organs transport technological systems of the adapted machines are for harvesting of root crops. Key word: technological process, heap of roots, material balance, flow, input weight, components of heap, combined purifier, balance of the masses, input mass.
