The process of human adaptation to the Arctic conditions is accompanied with changes in psychophysiological indicators such as strength and mobility of nervous processes. Extreme conditions have a strong impact on a human brain. This effect is different for people with different laterality. Laterality indicates functional asymmetry of two brain hemispheres. The authors propose software-based evaluation...
Literature analysis shows existence of data about weather influence on man's diseases. Selection of diseases in Arkhangelsk region from multifunctional information system was made. Analysis of people prevalence in several human settlements of Arkhangelsk region by means of statistic methods was conducted. The analysis demonstrated dependence of people prevalence on weather conditions as follows: a...
Preservation of biological diversity is one of priority tasks of the present time. Monitoring of the population during the migration from Europe and nesting on the coast of the Arctic Ocean plays an important role in the protection of European geese population. Traditionally, the main methods of geese population monitoring are those of route and area recording. The authors propose to study geese populations...
Obtained during reporting period important results are considered as new for science. Up to now there were not any publications describing species composition of fauna and ground beetles of European area of Arctic ocean during the whole season. It is ground beetles that represents bright indication of ecological situation change in circumpolar region. For the first time we compiled a close to comprehensive...
Modern students have been brought up on the literature in the style of “fantasy” and computer games, so reading scientific literature and watching science films seems boring to modern students. To solve the problem of increasing students' interest in learning we offer a MOOC in form of “Quest”-style.
Barents region has an exceedingly complex structure of the surface in terms of geography. This region contains many impassable places. Theoretically, for the construction of surface area covered by KA-SAT satellite signal measurements should be carried out in all the nodes of the 50×50 km grid. Actually, due to the lack of roads conducting such measurements is not possible. The authors made the maximum...
Providing workers with telecommunication services in the Arctic is a very important task. To supply devices with power petrol and diesel generators are traditionally used. Delivery of fuel to the Arctic is difficult, unprofitable and threatening the environment. The authors suggest use alternative energy sources for autonomous satellite communications platform power supply. The work deals with the...
The paper deals with the device for determining the critical flicker fusion frequency (CFFF). CFFF method is used in ophthalmology and physiology as an indicator of functional lability of the retina and visual pathway. Based on the analysis of available solutions, authors describe the creation of a new instrument. The main advantages of the device are the following: small size of glasses and instrument,...
This paper is dedicated to the process of creating an information system built on the basis of the synthesis of long-term field studies and available in literature data about ground beetles of North. Research issue aims to identify adaptations of ground beetles for the life in the north of the Russian Plain. These very ground beetles are striking indicator of change of the environmental situation...
For the Arctic exploration it is necessary to provide polar explorers with reliable high-quality communication equipment: satellite complex, router, wireless network. To supply with communications equipment and computer network a stable power supply is needed. A possible solution of the problem is the usage of alternative energy sources (solar panels, wind generators, batteries). In this paper we...
Obtained by the authors in 2013 data about the actual coverage by signal of 75th and 76th beams of satellite Ka-Sat in the Arkhangelsk Region, the Murmansk Region and Nenets Autonomous District, the Barents and White Seas does not match with the theoretical coverage area. In 2014 the authors organized a new expedition in order to receive new data. The data obtained were processed using algorithms...
Parents is disturbing about effect on radiation electromagnetic safety to children organism when provide wireless network in school. Author considers correspondence of russian and foreign safety standard of E-field radiation, and came to conclusion that Russian standard is more harder. Researches of E-field radiation influence to human brain come to the conclusion that blood-brain barrier, protecting...
Arctic Development is one of the strategic goals of Russia and other circumpolar countries. Solution of this problem is faced with the problem: most of the coastal seas and the Arctic Ocean is covered with ice. For large vessels and icebreakers problem is solved by applying remote sensing of ice with spacecraft and aircraft. This solution has a very high cost and low efficiency. The authors propose...
Many of current web search engines rely on inverted index-based data structures as document information store. Since and inverted index is a map from individual document words to their respective locations, such data structure destructs semantic links between the words, and thus does not support structural user queries. In other words, such systems can only find the documents that contain user-specified...
The main objective of the project - to provide new data about the signal strength and coverage of the actual signal Ka-band beams 75 and 76 satellite Ka-Sat in the Arkhangelsk region, Murmansk Oblast and Nenets Autonomous District, the Barents and the White Sea and the development of experimental design of the sample measurement equipment Ka-band for the Far North. Applications coverage maps - Arkhangelsk...
The urgency of research issue is caused by that the hepatorenal syndrome problem is actively studied more than 100 years, however remain unresolved some question on treatment of such patients, therefore the high death rate remains. Creation of the software product «Hepatorenal syndrome screening» is the important stage in hepatorenal syndrome screening. The developed application will allow without...
One of Wifi-networking problem is access points location. Networking of IEEE 802.11n standard raises the issue complicated because of standard analysis don't take into consideration electromagnetic wave reflection from surface indoor. Author suggests to use geometric theory for access points location optimization.
