Abstract The paper presents the main ideas of the virtual test bench concept for rapid obtaining of the reliable characteristics of compressors based on a multi-level mathematical model with a two-step identification using data obtained from mathematical models with a high order of accuracy. One of the possible identification algorithms and the results of its successful testing are given on the example of a centrifugal compressor stage developed and tested at NASA.

Abstract The research studies the features of coverage of the Syrian conflict by Russian media. In scientific discourse, there are a number of works studying the information support for the civil war in Syria, which is explained by its specificity – a multilateral, multi-level protracted conflict creates an opportunity for a varied interpretation of events and causal relationships. The way events in Syria are presented in various regions of Russia is of particular interest. In the course of this study, a database of media articles, both federal and regional (Dagestan, Tatarstan, Chechnya), was collected. The articles were then analyzed from the point of view of the prevailing semantic codes, which made it possible to identify how the Syrian conflict is framed, as well as the similarities and differences of different regions’ frames.

The article is devoted to the development of software of information and analytical support for regional security management. The authors formulate the concepts of configuration of a network-centric management support system and its dynamic configuration. The conceptual scheme of the configuration in the notation of ER diagrams and its implementation in the form of a configuration file is proposed. The technology for dynamic configuration of multi-level network-centric information and control systems is described. The technology is designed for automated deployment of a network of software agents and their parametric configuration depending on the context of the application problem being solved

Introduction: to strengthen the Union State of Belarus and Russia, it is necessary to use a complex of effective and multi-level pro-integration mechanisms. An important place among them belongs to public associations focused on formation and promotion of a positive integration agenda significant not only for the political elites, but also for citizens of the both countries. Objectives: to check the hypothesis about the agency function of public associations in the process of Russian-Belarusian integration. Methods: traditional and formalized study of documents and Internet resources, as well as binary analysis. Timeline of content analysis is 2019 − first half of 2021. Results: the program documents of four public associations were analyzed: in the Russian Federation − the All-Russian Public Movement “People’s Front” for Russia”, the All- Russian public organization “Russian Union of Youth”; in the Republic of Belarus − the Republican Public Association “Belaya Rus” (“White Rus”) and the Belarusian Republican Youth Union. The level of interest of these public associations in covering integration issues was determined by analyzing the content of their Internet resources (official sites and groups on VKontakte social network), and the users’ interest in posts on this topic was studied. The authors provide practical recommendations for national and union government bodies. Conclusions: the integration component is clearly expressed in the program documents of two public associations: the All-Russian Public Movement “People’s Front” for Russia” and the Republican Public Association “Belaya Rus” (“White Rus”). An analysis of the content of the public associations’ Internet resources allows interpreting their positions as pro-integration, but with a large degree of convention. There is a steady interest of users in posts on the issues of Russian-Belarusian integration, as well as in posts related to other vectors of integration, including the European one. On the whole, the considered public associations cannot be recognized as successful integration agents. The current situation can be corrected by securing the special status of public associations under the bodies of the Union State of Belarus and Russia developing and implementing new joint projects, expanding information support for creating the Union State and promoting the advantages of Russian-Belarusian integration.

Off-axis electron holography has the well known ability to preserve the complex image wave within the final, recorded image. This final image described by I(x,y) = I(r) contains contributions from the image intensity of the elastically scattered electrons IeI (r) = |A(r) exp (iΦ(r)) |, the contributions from the inelastically scattered electrons IineI (r), and the complex image wave Ψ = A(r) exp(iΦ(r)) as:(1) I(r) = IeI (r) + Iinel (r) + μ A(r) cos(2π Δk r + Φ(r))where the constant μ describes the contrast of the interference fringes which are related to the spatial coherence of the electron beam, and Φk is the resulting vector of the difference of the wavefront vectors of the two overlaping beams. Using a software package like HoloWorks, the complex image wave Ψ can be extracted.

For the calculation of X-ray intensities emitted by elements present in multi-layer systems it is vital to have an accurate knowledge of the x-ray ionization vs. mass-depth (ϕ(ρz)) curves as a function of accelerating voltage and atomic number of films and substrate. Once this knowledge is available the way is open to the analysis of thin films in which both the thicknesses as well as the compositions can usually be determined simultaneously.Our bulk matrix correction “PROZA” with its proven excellent performance for a wide variety of applications (e.g., ultra-light element analysis, extremes in accelerating voltage) has been used as the basis for the development of the software package discussed here. The PROZA program is based on our own modifications of the surface-centred Gaussian ϕ(ρz) model, originally introduced by Packwood and Brown. For its extension towards thin film applications it is required to know how the 4 Gaussian parameters α, β, γ and ϕ(o) for each element in each of the films are affected by the film thickness and the presence of other layers and the substrate.
