Near-Earth Space as an Object of Global Monitoring
Near-Earth space is analyzed as a specific object for global monitoring. The structure and specific features of nearEarth space are considered. It is shown that this zone includes almost all the terrestrial fields and the regions where space is actively explored by man
This article presents data on the current state of Russian space industry and describes its short- and medium-term development prospects. The analysis is based on statistical, research and government policy documents which allow to identify key trends and development directions of space-related science and technology in Russia in the year 2012-2013. Significant attention is paid to analysing strategic and projected data and programmes approved by public authorities. These allow to identify the steps taken to regulate space industry, major government policy tools and, goals and objectives set for the immediate future. Of particular interest are projects implemented during the period in question, and those planned for the near future. These projects cover all key areas of space exploration and space-based Earth observation. Development prospects for space-related services are analysed for the following segments: manned spacecraft launches, space navigation satellites, and remote sensing of the Earth. An important topic in this article is international cooperation and its prospects for the near future.
The article analyzes the near-Earth space as a future habitat for humankind. This article investigates the factors affecting the location in this environment. We estimate the boundaries of space and related space. The article highlights the main features of the near-Earth space as a human-friendly environment.
The article describes thefeatures of comparstive planetary science as academic discipline. The article shows the components of the Comparative Planetology. The article reveals the integration aspect of the discipline. The article compares the Geo-Informatics and Comparative Planetology.
In the paper the problem of space debris. Describes the causes of debris in near-Earth space. Describes the distribution of debris in near-Earth space. Shown that the accumulation of debris consists of two rings. Analyzes the statistics of debris. We analyze the spatial distribution of debris. Conjectured form rings debris in near-Earth space.
The article explores the specificity of relationship between the USSR/RF and DRV/SRV during and after the Cold War, as well as of cooperation between the EAEU and SRV in 2015—2019. The distinctive features of each of the stages in the Soviet/Russian policy is revealed, the success and failure factors in various periods are addressed, promising directions of the current Russia-Vietnam dialogue are identified. In the authors’ view, the EAEU factor is unlikely to play an important role in increasing cooperation between the Russian Federation and the Socialist Republic of Vietnam. Instead, for Russia it is expedient to offer Vietnam cooperation in technologically advanced spheres, among which digital security, space exploration and medicine can be distinguished, linking them with the Vietnamese, as well as with the Russian, prospective planning. The authors argue that this approach will be behind the Russia-Vietnam cooperation which will be strategic, i.e. futureoriented, and comprehensi ve, i.e. embracing many directions, living up to its formal status — the Comprehensive Strategic Partnership.
The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
Radiation conditions are described for various space regions, radiation-induced effects in spacecraft materials and equipment components are considered and information on theoretical, computational, and experimental methods for studying radiation effects are presented. The peculiarities of radiation effects on nanostructures and some problems related to modeling and radiation testing of such structures are considered.
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
