Predictive and migration trends of Russia in the context of Covid-19 pandemic and post-coronavirus world

This work discusses the trends of the world migration processes development in the context of global COVID-19 pandemic reflected in mass-media practices, network communication and scientific analyses. The methodology of this research is based on systematic methods of evaluating messages in the media and social networks, as well as network analysis techniques, mass media practices and migrant rhetoric in public materials by highlighting, comparing, evaluating and conceptualizing the trends in transformation of migration processes under the influence of global changes caused by the pandemic.

Digital migrants and digital diaspora: new problems and trends of international migration

The “Digital migrant”, as a concept, is used to refer to a migrant who realises his information needs by information digital technologies. This give rise to new trends in international migration processes, among which the global informatisation can be highlighted. This is expressed in the mass representation of migrants in social networks, in virtual network migrant communities’ creation. The digital diaspora being an electronic platform is the basis for migrants’ access to online public content, serves as an information base for the migrants’ digital adaptation and their virtual identity’s formation, which is becoming more and more transnational.The article proposes an instrumental definition of “digital migrant” concept, reveals factors of digital ethnic national community’s functioning, features of migrants’ social adaptation in digital diaspora, new types of interpersonal communication in digital diaspora, new trends and problems of digital migration, and new types of migrants’ identity and of digital virtual identit

Constrained minimization in the C# # environment

Abstract On the basis of the ideas, proposed by one of the authors (I.N. Silin), a suitable software has been developed for constrained data "tting. Constraints may be of arbitrary type; i.e. equalities and inequalities. The simplest possible way has been used. The widely known program FUMILI was re-written in the C# # language. Constraints in the form of inequalities ( )5a were taken into account by changing them into equalities ( )"t and simple inequalities of type t5a. The equalities were taken into account by means of quadratic penalty functions. The suitable software was tested on the model data for the ANKE setup (COSY accelerator, Forschungszentrum JuK lich, Germany)
