  • Using hardware in the loop simulation in design of data-measuring and controlling systems

    Today’s trend of electronics complicating makes developers to create more complex devices in a shorter time. Developers have to contrive different ways of designing automatization to prevent production worsening. However, automatization cannot improve the situation when an innovative device is developing because such developing involves a lot of testing and researches. In this article authors propose to use hardware in the loop simulation methods to optimize designing process. Hardware in the loop simulation is division the device in functional blocks, some of them are produced as models and other are produced as hardware. Usage of this method decrease cost of modernization hardware blocks and allow using a number of data processing algorithms at the same time.
    The article contains a using of hardware in the loop actuality description, main steps of designing enunciation and description of method exemplified by designing of data-measuring and controlling system for automatic orientation of tropospheric communications station.

  • Interactive training programs in educational process on household refrigerating appliances

    In article the material about use of interactive training programs in educational process of the students training difficult household appliances is prepared. 
    Within transition of the higher educational school to provisions of Bologna Process by a leading method of pedagogical work there is a competence-based approach to formation of steady knowledge and practical skills at students [1]. Indispensable condition thus is compliance of quality of training and the general education standard. As especially important requirement continuous control of assimilation of educational information and ability of its application serves in practical activities. The most well-tried remedy of total control of assimilation of educational information is carrying out daily testing, including remote. Use of test interactive programs becomes more actual at integration of groups and increase of an academic load on the teacher [2].
