Экспериментальная оценка возможности резервирования авиационных локальных дифференциальных подсистем СРНС с помощью импульсно-фазовой РНС
The paper considers the experimental assessment of an opportunity and effect of reservation of aviation local differential SRNS subsystem by pulse-phase RNS. Provision for a non-precise approach (NPA) is shown according to the ICAO regulations.
The article is devoted to the key problems related to the financing of innovation projects by commercial banks in Russia: the high risk of credit uncollectibility, the deficit of long-term bank resources, the specific profile of the potential company-borrower and others. To solve these problems the experience of foreign countries seems to be valuable in case of its adaptation to the Russian context.
Incorporation of blended learning into educational process is complex and challenging. The chapter aims to elucidate educators’ and students’ engagement and attitude towards the use of computer-mediated communication and social net sites in general, and for educational purposes in particular, in order to single out the issues that are controversial and slow down the use of ICT in teaching practice. It presents university teachers’ and students’ opinions collected by observation and interviewing. The results of the study, based on the fourth-generation method of assessment, reveal that both students and educators are active users of SNS and are optimistic about their integration into educational process. However, despite all the advantages of SNS disclosed in the study, still there are some issues to overcome before SNS can become an integral part of educational process. At present, its use should be supported by other means like LMS or MOOCs as well as traditional on-campus activities.
Generalized error-locating codes are discussed. An algorithm for calculation of the upper bound of the probability of erroneous decoding for known code parameters and the input error probability is given. Based on this algorithm, an algorithm for selection of the code parameters for a specified design and input and output error probabilities is constructed. The lower bound of the probability of erroneous decoding is given. Examples of the dependence of the probability of erroneous decoding on the input error probability are given and the behavior of the obtained curves is explained.
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.
