The article considers a new methodology for specialist training in the field of microprocessor control systems based on filling an educational process with jobs of real practical content which’re performed by project team in the conditions of the access absence to a laboratory equipment. The matter is that during the study of theoretical disciplines of technical trend, practical classes, fulfilled in the form of laboratory works, are aimed at fundamental knowledge confirmation in a subject area by the way of experiment conduction, at that, experiments themselves can be organized not only on a laboratory equipment but also in modeling programs. The stated goals for theoretical information backing are achieved by fulfillment laboratory work and subsequent defense. Together, in training programs for specialists in applied technical spheres, for example, in the program of specialist preparation on "Control in technical systems" course, it’s provided the study of disciplines in which practical content prevails over theoretical one. Thus, for example, in the course "Electronics and fundamentals of microprocessor technology", it’s taught a necessary theoretical basis for the discipline "Microprocessor devices of control systems", and in the program itself of the pointed discipline, it’s provided the study of device construction approaches with the use of universal microprocessors and microcontrollers as well as of programming basics of them. Namely that is why in the curriculum of "Microprocessor devices of control systems" discipline, there’re provided not laboratory but practical works which in the course, students, performing tasks, program microcontrollers which interact with external devices in simple but functionally complete control devices. However, a laboratory equipment turns out to be unavailable during distance learning that predetermined the search for alternative forms of organization of practical works out-of-door of a university. The search for a suitable solution, besides the solution of laboratory equipment unavailability problem, led to the possibility to organize practical works with the use of a management project method.
The problem of specific filtering is relevant due to the increased threats of information security in educational organizations. To date, there is a problem in studying the basic functionality of filtering systems from unwanted content in network traffic. To solve this problem, it is necessary, firstly, to analyze the main methods of traffic filtering and the requirements of content filtering in educational institutions when using the Internet, and secondly, to create, implement and configure software for filtering the content of educational sites.
The article discusses the issues of implementation and organization of high-speed transport. The objective of the article is to consider possible options for implementing highspeed (HS) motion systems using the principle of magnetic levitation, which will ensure high speeds for delivery of goods and carrying people over long distances. To achieve this objective, it is necessary to develop an engine and technical solutions for design of HS rolling stock, make decisions on energy supply infrastructure and the HS track, address safety issues and new control systems considering the state of the infrastructure and its design elements. The article discusses several options for implementation of high-speed transport systems, differing in the power supply system, current collection and track based on the magnetic levitation approach. An original approach is proposed in implementation of magnetic levitation transport using the technology of electromagnetic guns designed to implement traction forces of a magnetic levitation vehicle. The advantage of this approach is that it opens the possibility of maneuvering for the vehicle while driving. This allows to abandon switch turnouts, now significantly limiting the use of magnetic levitation transport. A mathematical model describing interaction of an electromagnetic gun and supermagnets located on the track is considered. In constructing the model, methods of the theory of electromagnetic field and interaction of magnetic bodies were used, and when constructing a model of interaction of rolling stock with a magnetic track, methods of mathematical algebra and the Cauchy theorem were used. The article discusses various principles of organization of movement using the magnetic levitation for urban, suburban, and intercity transport.
