Pozhidaev E.D., National Research University Higher School of Economics, ul. Myasnitskaya 20, Moscow, 101000 Russia, EPozhidaev@hse.ru

Abstract: A physic-mathematical model of radiation electrization of composite polymer film materials having controlled dark conductiyity was proposed, taking into account the time-varying value of its radiative conductivity. Computer simulations have been carried out for radiation electrization of composite low-density polyethylene films having controlled electrical specific conductivity 10-7-10-16 Ω-1•m-1 in case of values of a flow of electrons 10-7 A·m-2 (corresponds to conditions of a quiet geomagnetic situation) and 10-5 A·m-2 (corresponds to conditions of atypical geomagnetic substorm). It is shown, when the radiation conductivity is commensurable with the dark conductivity, it substantially slows down the increase of the electric field strength over radiation time. It is shown on the example of films of PENP that application of the composite dielectric films having controlled specific dark conduction 10-9-10-10 Ω-1•m-1, allows to exclude completely electrostatic discharges even in the conditions of course of a geomagnetic substorm.

Organization of adaptive streaming of video using CDN and distributed load balancing using the Nginx web server

Nekrasov G.A., National Research University “Higher School of Economics”, Moscow, Russia, alax-27@mail.ru

Romanov A.Yu., National Research University “Higher School of Economics”, Moscow, Russia

Abstract: The article is devoted to the development of an automated service for the media content delivery network in the organization of adaptive online streaming on the Internet. This organization of broadcasting of video streams allows to automatically adjust the amount of transmitted data per unit of time (further bit rate), changing the quality of the requested media content accordingly. As a result, the quality will be underestimated for those users who use data channels with low bandwidth, and vice versa, for those users who are connected to high-bandwidth communication channels, the content will be provided with the highest possible quality. In this process, the user does not take any part: the client video player itself determines which bitrate will optimally display the content to a specific user in order to avoid buffering the video, but at the same time ensure that it is displayed in the highest possible quality. Switching between bitrates can occur continuously with both a decrease and an increase in bit rate, depending on changes in the quality of the currently available bandwidth. In addition to the adaptive video broadcasting service, the developed service allows you to transcode video streams on the fly. By accessing the RTSP / RTMP stream, the network converts it into RTMP / HLS-multibitre, resulting in the generation of video streams of different quality, supported by both mobile devices and personal computers.

Keywords: CDN, content delivery network, adaptive streaming, streaming online broadcasting, media content, multi-bitrate, RTSP, RTMP, HLS.

Development of a field agro robot movement control system

Egorova M.V., Moscow Aviation Institute (National Research University), 812 Chair, Lead Engineer

Abstract: This article reviews the existing solutions and methods for organizing the management of robot movement in the agricultural sector. The characteristics that the robot motion control system should have for technological processes of cultivating cultivated crops should be justified, and a specific control object should be selected. An algorithm was proposed for autonomous control over the movement of field agro robots based on fuzzy logic. The possibilities of fuzzy inference allow defining rules for movement and circumvention of arising obstacles, without having specific data on the robot motion model. The structure of the motion control system was developed, during which the basic elements of this system were determined: fuzzy controller, Vision System, rangefinders, navigation system, left and right track drives and data receiving and transmission module. To implement the algorithm, a fuzzy controller model was created and a program was developed in the C # programming language to demonstrate the operation of the algorithm in various situations. The program allows you to specify consecutive points of the trajectory of movement of the robot and have obstacles, then observe the operation of the algorithm.

Keywords: agro robot, control system, controller model.
