Уровень медиаграмотности населения РФ: текущее состояние и перспективы изменения (на основе всероссийского мониторинга медиаповедения)
The article presents some of the results of the project "Monitoring the Russian media literacy of the population", which is being conducted by ZIRCON Research Group since 2009. The latest whole-Russian mass survey was conducted in the autumn 2015.
In the last years native RDF stores made enormous progress in closing the performance gap compared to RDBMS. This albeit smaller gap, however, still prevents adoption of RDF stores in scenarios with high requirements on responsiveness. We try to bridge the gap and present a native RDF store “OntoQuad” and its fundamental design principles. Basing on previous researches, we develop a vector database schema for quadruples, its realization on index data structures, and ways to efficiently implement the joining of two and more data sets simultaneously. We also offer approaches to optimizing the SPARQL query execution plan which is based on its heuristic transformations. The query performance efficiency is checked and proved on BSBM tests. The study results can be taken into consideration during the development of RDF DBMS’s suitable for storing large volumes of Semantic Web data, as well as for the creation of large-scale repositories of semantic data.
The need for transmission and storage of large amounts of scientific data in the project space radio telescope ”Radioastron” required us to organize a reliable communication channel between the tracking station in Pushchino and treatment centers in Moscow. Network management data requires us to an integrated approach and covers the organization secure access to manage network devices, timely replacement of equipment and software upgrades, backups, as well as documentation of the network infrastructure. The reliability of the channel is highly dependent on continuous monitoring of network and server equipment and communication lines.
Methodology of automated forming of weak-formalized manufacturing documents for support the production processes of an enterprise on the basis of the cybernetic methods is considered. A model of elaboration of automaed documents preparation technology with use of automated lexicological synthesis is presented. The technology being proposed allows substantially reduce the man-hours at making of full-text documents.
The report discusses methods and software tools for the creation of information-analytical system (IAS) monitoring of dangerous celestial bodies and planning Asteroid-comet hazard (ACH). The article provides a description of the structure of the system and its functional components to enable rapid assessment of potential threats and forecast the effects of a collision dangerous space objects to the Earth. The result of the system is the integrated analytical information about the possible risks for the decision to reduce the possible damage and to identify effective measures for emergency management of cosmic origin.
Over the last decade aural and visual monitoring of massive people gatherings has become a critical problem of national security. Whenever possible a fixed infrastructure is used for this purpose. However, in case of spontaneous gatherings the infrastructure may not be available. In this paper, we propose the system for spontaneous “flash crowd” monitoring in areas with no fixed infrastructure. The basic concept is to engage users with their mobile devices to participate in the monitoring process. The system takes on characteristics of “big data” generators. We analyze the proposed system for coverage metrics and estimate the rate imposed on the wireless network. Our results show that given a certain level of participation the LTE network can support aural monitoring with prescribed guarantees. However, the modern LTE system cannot fully support visual monitoring as much more capacity is required. This capacity may potentially be provided by forthcoming millimeter wave and terahertz communications systems.
