  • On the issue of creating heavy energy objects: in the symbiosis of wildlife, mechanics and artificial intelligence

    This paper considers non-traditional methods for creating an optimal technological process for the manufacture of heavy energy objects using the principles of wildlife. A comparative analysis is carried out between the principle of operation of the developed version of a reloading machine for fuel cells in a nuclear reactor, various options for load-gripping and suspended manipulating devices, and analog processes borrowed from nature. The scheme of manufacturing a heavy energy object is analyzed when considering the chain "mechanics - spider, ant - hoisting-and-transport machines - engineering psychology".

  • 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.
