Представляем работы Виктора Чумачева
Виктор Чумачев – известный московский художник, который сотрудничает с «Системным администратором» уже несколько лет. Именно его забавные и воздушные, как ИТ, иллюстрации украшают многие серьезные статьи в журнале. Работы Виктора Чумачева хорошо знакомы читателям в России («Комсомольская правда», «Известия», «Московские новости», Коммерсант и др.) и за рубежом (США, Германия). Каждый раз, получая новый рисунок Виктора, мы в редакции улыбаемся. А улыбка, как известно, смягчает душу. Поэтому смотрите на его рисунки – и пусть у вас будет хорошее настроение!

Optimization of recognition technology for streaming data

Povalyaev P.P., Moscow Aviation Institute (National Research University), Master, pavel.povalyev@gmail.com

Abstract: The article presents the technology of data recognition with high speed. The system allows to significantly reduce the time spent on processing one frame, and also improves the quality of the result. To implement this technology, a low-level WebAssembly programming language was chosen, this application runs in the browser and is a portable abstract syntax tree. Scheme of work "client-server".mization were determined, its general features and application prospects were described.

Repin M.M., lecturer, Moscow Polytechnic University, direction “Information security”, bmstu.iu8@gmail.com

Przhekotskaya E.A., Ph.D., Associate Professor of the Faculty of Informatics and Management Systems, Head of the Educational Program “Security of Advanced Information Systems”, Moscow Polytechnic University

Plotkin A.S., student, Moscow Polytechnic University, direction “Information Security”, sances.98@mail.ru

Krivonogov A.A., student, Moscow Polytechnic University, direction “Information security”, boozer273@gmail.com

Abstract: To solve various problems in the our world, information technology is increasingly being used. There is an annual growth trend of cyber threats to information resources, and their protection is one of the most important tasks. The solution of this problem requires the preparation and adoption of organizational and technical measures to ensure the cybersecurity of information resources. The basis for building any system of protection from cyberthreats is a risk analysis. This article discusses some of the methods that are not currently used in the field of information security, but potentially applicable in the future.

Keywords: risk management, risk analysis, information security risk analysis methods application.

Computer simulations for radiation electrization of polymer composite materials having controlled electrical conductivity

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.
