Автоматизоване розпаралелювання програми моделювання внутрішньочастинкової дифузії й абсорбції в неоднорідних нанопористих середовищах

Heterogeneous media consisting of thin layers of particles of forked porous structure with different physical-chemical properties are widely used in science-intensive technologies and priority sectors of industry, medicine, ecology, etc. Such layers are distributed systems of pores consisting of two main spaces: micro- and nanopores of particles and macropores and cavities between particles. Mass transfer in the system of heterogeneous media causes two types of mass transfer: diffusion in macropores, owing to interparticle space, and diffusion in the system of micro- and nanopores inside particles of the heterogeneous medium. Intraparticle space has a higher level of adsorptive capacity, and at the same time, has a lower velocity of diffusion intrusion in comparison with interparticle space. In modeling concentra- tion and gradient fields for various diffusible components, an important scientific problem is the identification of kinetic parameters of a transfer, predetermining mass transfer velocity on macro- and micro levels, and also equilibrium conditions. The results of designing and parallelization of a program implementing a Crank-Nicolson scheme using algebra-algorithmic specifications represented in a natural- linguistic form are given. The tools for automated design, synthesis and auto-tuning of programs were applied that provided the translation of algebra-algorithmic schemes into source code in a target programming language and its tuning for execution environment to increase the program performance. Numerical distributions of values of diffusion coefficients for intraparticle transfer along coordinate of medium thickness for various time snapshots were obtained. Based on the results of the identification, the models were checked for adequacy and numerical modeling and analysis of concentration and gradient fields of mass transfer were carried out. The experiment results of auto- tuning the software implementation demonstrated high multiprocessor speedup on test data input.

ROLE AND PLACE OF IMPLEMENTED INNOVATIONS IN THE AGRICULTURAL SECTOR OF UKRAINE

The article is devoted to the role and place of higher education institutions in the implementation of innovations in the agricultural sector of Ukraine. Traditional farming practices have been proven to be improved and modified through automation and the introduction of modern, large-scale technological solutions that reduce risk, increase resilience and provide producers with predictive solutions to make agriculture more productive. The positive side of the transfer of knowledge is the opportunity for ZVO to get an additional way to diversify sources of income, thereby turning it into a subject of entrepreneurship in the regional economy. Implementation of innovative activity requires the presence of a system of its organization. It was called the knowledge transfer system. The most important factor in the effectiveness of knowledge transfer processes is the presence of an appropriate organizational infrastructure, which acts as an “exchange buffer” between external customers and university units, its teachers and scientists. The expansion of cooperation between subjects of the Regional Innovation System is crucial for encouraging the wide use of academic knowledge as innovations in the regional economy. Based on the concept of reviewing the role of higher education institutions as a generator of knowledge development in society, we considered the possibilities of organizing the interaction of interested parties, including business representatives and government bodies. We believe that an institute that would consolidate the scientific and technical structures of large companies, research stations and laboratories, institutions of higher education, venture investment firms, investment funds and companies, insurance companies, credit cooperatives, consulting and other specialized services, i.e. about objects that carry out various stages of the investment cycle can become an agroinvestpark. We believe that its creation will contribute to the unification of efforts in the organization of educational, research, investment and innovation activities, the improvement of the educational process of training specialists for the needs of the agricultural sector of Ukraine, the development and offering of science-intensive technologies and innovative developments on the market. Therefore, in order to promote the innovative activity of agricultural enterprises, it is necessary to develop a comprehensive and systematic personnel policy as a consistent activity of state authorities and local self-government bodies for the purpose of rational use and reproduction of the personnel potential of agriculture. We believe that for this purpose it is necessary to improve the quality of training of specialists in educational institutions of agricultural education, to reform the system of retraining and advanced training of personnel at all levels of professional education, to ensure the adjustment of training programs based on shifting the emphasis to practical training for the introduction of progressive technologies and equipment.

The article examines the features of the doctrinal basis of the Norwegian policy in the Arctic, as well as the military-political strategy to ensure the security of the region. The doctrinal framework of Norwegian policy will put Arctic strategy at the forefront. It has been established that Norway owns the systemic regulation of the legal issues of the Arctic region among the Scandinavian countries, serving at the same time as a kind of model for working out mechanisms to defend interests at the regional and international levels. At the same time, it is Norway that owns an innovative approach to the development of hydrocarbons in the Arctic, to the development of a green economy, which are based on environmental protection, the introduction of science-intensive technologies, incl. alternative energy sources. The doctrinal basis of Norwegian policy towards the Arctic region is characterized by specific directions, where the priority is mainly international cooperation, business development, knowledge development, infrastructure, environmental protection and emergency preparedness. The conceptual basis of Norway's doctrines in the field of Arctic region policy consists of the integration of knowledge, science and business, with the aim of sustainable development of the Arctic. In the doctrinal basis of Norway, security issues and the military-political strategy in relation to the Arctic region play an important role. These issues are regulated by such international relations as NORDAC (Nordic Armaments Cooperation), NATO and the maintenance of bilateral relations and partnership with Russia. In Norway's security policy, the main role is played by the NATO strategy, which is based on systemic exercises of practicing military action in the Arctic and the fulfillment of certain missions by Norway due to the recent Crimean events.

Preliminary analysis of the possibility of using REMIX fuel in VVER-1200 reactors of the Belarusian NPP

The transition from conventional uranium to regenerated fuel, which uses reprocessed spent fuel and enriched natural uranium, improves fuel efficiency and reduces the amount of spent nuclear fuel (SNF). Based on the analysis of published materials concerning mainly the fuel cycles of the VVER-1000 reactor, it was concluded that the most suitable in the conditions of the Republic of Belarus is the use of REMIX fuel. To confirm this conclusion in relation to the VVER-1200 reactors of the Belarusian NPP, computational studies were carried out within the framework of the State program “Scienceintensive technologies and equipment” for 2021–2025, subprogram 3 “Scientific support for the effective and safe operation of the Belarusian nuclear power plant and promising directions for the development of nuclear energy”. The characteristics of a 12-month fuel cycle with multiple recycling (reuse of fuel) according to the REMIX technology with 19.75 % enrichment of added uranium and maintaining the design capacity and duration of the campaign have been obtained. The share of SNF that is not returned to the reactor is 12.8 % (for a cycle with uranium fuel – 100 %); the fraction of waste intended for disposal or long-term storage, respectively, decreases by 8 times, and the specific consumption of natural uranium is reduced from 202 g/(MW·day) for uranium fuel to 159 g/(MW·day) for REMIX fuel. The results obtained can be taken into account when developing a fuel use strategy at the Belarusian NPP.

Генезис проблемы формирования цифровой межкультурной компетентности в период с 1970-х до начала 2000-х гг.

The analysis of works on the problems of vocational education pedagogy made it possible to highlight the crisis points in its development, associated, first of all, with the inconsistency of the educational results content with the requirements of employers and the priorities of state policy in the field of digitalization and innovation. The system of forming employees' key competencies has become one of the priority conditions for the creation and effective functioning of the Russian state innovative economy. The active and widespread introduction of modern science-intensive technologies leads to an increase in the requirements of the state and society for the qualifications of university graduates, the level of their intercultural competence, and readiness to master new approaches to professional activity. These factors explain the close attention of scientists and specialists from different branches of knowledge and areas of pedagogy, psychology, public administration, sociology, informatics, etc., to the problems of intercultural training of future specialists in the context of globalization. The article proposes the periodization of the development of the problem of forming digital intercultural competence, the identification of characteristic trends at the second stage of the problem development, the identification of socio-cultural, historical, scientific and theoretical prerequisites for its formation and development. At the same time, the etymological complexity and diversity of the research problem led to the identification of historical trends in several directions: emergence of information society; formation of the competence nature of the higher education system; development of the problem of forming intercultural competence.

Retrospective analysis of foreign investment in the context of the evolution of economic theories

The article provides a retrospective analysis of the formation and evolution of foreign direct investment in terms of various economic theories taking into account changes in the stages of socio-economic development. The study of these historical and economic issues was carried out using systematic analysis and historical method; which allowed us to identify the genesis and analyze the evolution of economic theories on the formation and development of foreign direct investment. The author conducted a detailed study of the history of investment activities and management of foreign direct investment from the oldest origins in the ancient world to modern forms of innovation. It was found that at different times, repre- sentatives of various economic theories (open economy, market modernization, monopolistic competition, international capital movements, etc.) worked on under- standing complex investment processes, risk management and methods of obtaining economic benefits, who considered foreign direct investment as a guaranteed im- provement and development of society. The analysis of scientific literature and statistics shows positive social, po- litical, economic, technological and other effects of investment activities: job creation and training, export diversification and improvement of export perfor- mance, introduction of science-intensive technologies, activation of local firms – suppliers and subcontractors, the introduction of effective management methods, foreign exchange inflows, etc. Analyzing the genesis of economic theories, opinions and research, we conclude that humanity, feeling the need for savings, pays considerable attention to investment. The stages of the investment economy and the choice of methods of control over them indicate the urgency of this problem, and today scientists continue to discover new aspects of investment opportunities and develop innovative forms, mechanisms, tools of investment policy. Key words: economic theories, foreign direct investment, investment activity, international capital movement.
