  • Problems of interpartial merging and way of their decision when forming structure of powder steel 110G13P

    Stages of receiving samples of high-austenitic powder steel 110G13P a method of dynamic hot pressing are presented. Processes of formation of structure and properties of steklosoderzhashchy powder steel 110G13P are considered. Significant positive effect on formation of structure of powder steel 110G13P with application glass components is defined.

    Keywords: high-austenitic powder steel, method of dynamic hot pressing, agglomeration, mechanical activation of furnace charge, oxidic films

  • A systematic approach to the implementation of interactive forms of learning during lectures on technical subjects at university

    The introduction of new standards of higher education, especially the mentality of today's youth lead to the fact that the established methods of teaching classes in high school, by the way, is still widely practiced, do not allow the full interest of students and to provide high efficiency of development of the subject. In connection with the above, great interest is holding lectures with interactive forms obucheniya.Odnoy of the most effective and low-cost training in interactive forms a lecture scheduled errors (lecture-provocation). Teach people to think, quickly analyze professional situations, to act as experts, to work in a team - all this is possible if we use different kinds of interactive activities, including this kind as to the planned lecture errors.

    Keywords: systematic approach, improving the efficiency of the educational process, lecture scheduled errors, interactive activity, activation of learning and cognitive activity, technical discipline

  • The method of constructing a hierarchy of criteria on the basis of ontological analysis system

    The paper describes a method to build Jerah krietriev for solving decision making in the management of complex multivariable systems based on functional decomposition . The result of functional decomposition takes the form of an ontology -based posnroennoy deskriptinvyh logic to build a hierarchy of concepts. The advantage of this method is the ability to use it for semi-structured systems. The result of the ontological analysis of the functional structure of the system is the taxonomy, including a description of the processes , organizational structures, and indicators of quality of running processes . When referring to this ontology by using the proposed request is generated hierarchy of indicators , based on the processing of values ​​is carried out and decisions .

    Keywords: ontological analysis, systems analysis, ontology, descriptive logic
