  • Changes in the structure of the magnetic field MPFS TWT by external corrective action

    This article describes new method of correction of magnetic field MPFS TWT. The method allows controlling the magnetic induction instead of the current coefficient of retarding system. This approach reduces time and increases quality of correction. The key point of the method is in controlling of magnetic field on the assembly stage. The iteration algorithm of correction was developed. It is necessary to remember the coordination of the point, which need to be corrected. After measurement the researcher will know the result of influence of correction, which he or she applies to the system. In such way all magnetic system need to be controlled. This article represents the result of this approach and shows its benefits and lacks.

    Keywords: periodic magnetic focusing system, a traveling wave tube, the magnetic field, the electron beam

  • Sociographic measurement of cultural leisure young people in Rostov-on-Don

    This scientific research is directed on measurement of level of satisfaction of students with a cultural and leisure complex of Rostov-on-Don, ability of cultural infrastructure to sustain inquiries of the population, and reveals the problematic side of the existing cultural complex. Research took place from December, 2013 to May, 2014 by a questioning method. It's received low level of satisfaction with the functioning of the cultural complex among young people. Revealed a low level of interest of the population in their cultural development. It is shown that the existing cultural infrastructure is not able to fully perform their functions of the cultural development of the population and neeeds to change.

    Keywords: cultural complex, sociographic measurement, questionnaires, descriptive statistics, cultural infrastructure, cultural level of the population, leisure

  • Simulation of the converter devices transformer in Simulink

    The analysis of electromagnetic processes of thyristor controlled voltage regulator consisting of triple-wound transformer with thyristor units is possible only by means of computer modeling. The synthesis of triple-wound transformer  by means of block diagram method is concerned here. As a platform for modeling use visual simulation package Simulink. Key assumptions in the development of nonlinear mathematical model of the transformer are generally accepted.

    Keywords: three-phase transformer, thyristor voltage regulator, simulation, Simulink

  • Universal method of synthesis of optimal control of nonlinear Lagrang dynamic systems

    Universal method of optimal control synthesis offers a versatile method for the synthesis of optimal controls provides a solution to the synthesis problem for the class of piecewise constant functions for Lagrangian dynamical systems, the shape of the control law depends only on the structure of the cost functional and does not depend on the structure of the existing system of generalized forces. The effectiveness of the method is confirmed by a minimum of computational costs, as well as the maximum rate of convergence and accuracy to achieve the desired trajectory in comparison with the known solution for example has become a test for testing various control methods for the synthesis problem of a simple pendulum.

    Keywords: combined maximum principle, optimal control, mathematical pendulum

  • 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].
