One-rank interaction kernel of the two-nucleon system for medium and high energies
A new version of the separable kernel of the nucleon-nucleon interaction in
the Bethe-Salpeter approach is presented. The phase shifts are fitted to recent
experimental data for singlet and uncoupled triplet partial waves of the
neutron-proton scattering with total angular momenta J=0,1. The results are
compared with other model calculations.Comment: 10 pages, 5 figures, 3 table
Language system contacts or intersystem factors?
The paper examines the issue of reasons and mechanism of diachronic changes in the English language. The aim of the article is not to challenge the sociolinguistic origin of changes theory, but to provide a detailed description of the intersystem process. Step-by-step reconstruction of the process shows that three levels of the language system have taken part in it: accent logical, phonological and morphologica
Marketing management of the territory in the aspect of the regional brand formation
The importance of managing branding of territory in terms of satisfying the demands of domestic consumers and attracting external economic agents is mediated by the realities of modern economic development in various regions of the country and the focus on the formation of accelerated development territories.
These realities are characterized by unevenness. High competition between the territories in managing branding raises the importance of marketing management in territorial development and brand building.
The article contains the statement that the success of the brand of the territory facilitates its sustainable development, attracting new economic agents, increasing the confidence of the population and business partners in regional business, building social and economic potential, and creating territorial advantages.peer-reviewe
Assessment of quantitative risk indicators of electric power system operation in case of failure of the loads with responsible consumers
The article presents the basic ideas of assessment of quantitative risk indicators of electric power systems operation in case of failures of load with responsible consumers. It is proposed to use an integral risk index of functioning when evaluating the operational reliability of the EPS
Complex correlation of two language systems: modern literary German of Germany and Austrian variant of German
The article presents a research of Austrian variant of German lexical variety. German language of Germany is a pluricentric language. It exists in some variants: standard variant of modern literary German of Germany and two variants of German in Austria and Switzerland. The relations between the standard form of the language in Germany and its variant in Austria are the main issue of the researc
Healthcare improvement in the admission department of secondary healthcare facilities under counteracting the COVID-19 pandemic
The COVID-19 pandemic tested the strength of the Ukrainian healthcare system. At the same time, it provided high-powered incentives to improve measures to implement the second stage of health care reform The admission department is one of the most important hospital departments, which receives consumers of medical services in need of a qualifying examination and hospitalization under the protocol
РАЗРАБОТКА НЕЧЕТКОЙ НЕЙРОННОЙ СЕТИ ДЛЯ ИНТЕРПРЕТАЦИИ РЕЗУЛЬТАТОВ АНАЛИЗА РАСТВОРЕННЫХ В МАСЛЕ ГАЗОВ
Purpose. The purpose of this paper is a diagnosis of power transformers on the basis of the results of the analysis of gases dissolved in oil. Methodology. To solve this problem a fuzzy neural network has been developed, tested and trained. Results. The analysis of neural network to recognize the possibility of developing defects at an early stage of their development, or growth of gas concentrations in the healthy transformers, made after the emergency actions on the part of electric networks is made. It has been established greatest difficulty in making a diagnosis on the criterion of the boundary gas concentrations, are the results of DGA obtained for the healthy transformers in which the concentration of gases dissolved in oil exceed their limit values, as well as defective transformers at an early stage development defects. The analysis showed that the accuracy of recognition of fuzzy neural networks has its limitations, which are determined by the peculiarities of the DGA method, used diagnostic features and the selected decision rule. Originality. Unlike similar studies in the training of the neural network, the membership functions of linguistic terms were chosen taking into account the functions gas concentrations density distribution transformers with various diagnoses, allowing to consider a particular gas content of oils that are typical of a leaky transformer, and the operating conditions of the equipment. Practical value. Developed fuzzy neural network allows to perform diagnostics of power transformers on the basis of the result of the analysis of gases dissolved in oil, with a high level of reliability.Разработана и обучена нечеткая нейронная сеть для интерпретации результатов хроматографического анализа растворенных в масле газов. Предложено определять функции принадлежности лингвистических термов с учетом функций плотностей распределения концентраций газов для трансформаторов с различным состоянием. Выполнено тестирование обученной сети на независимой выборке. Проанализированы возможности нейронных сетей распознавать развивающиеся дефекты на ранней стадии их развития, или рост концентраций газов в исправных трансформаторах, после аварийных воздействий со стороны электрических сетей
Investment instruments to stimulate depressed regions’ development
There are a number of problems of regional development, including tgose that impress most of all – the growing differentiation and polarization of the regions’ development. It caused the emergence of so called depressed territories with the level of social and economic development being the lowest among the territories of this type. In this context, it is quite urgent to stimulate the development of depressed territories, in particular, the development and efficient use of investment instruments in this process.
This research aims at stipulating investment instruments to support the development of depressed regions. The article considers theoretical grounds of the emergence and functioning of depressed regions, foreign experience on financial support for the depressed territories’ development.
Based on experts’ survey, investment instruments to support the development of depressed regions are stipulated, peculiarities of forming priorities of developing depressed regions are specified, an algorithm for selecting top priority areas for economic activity in the depressed region is offered, a generalized system of financial instruments to stimulate the development of priorities for sustainable development of the depressed region is given, and consequences of applying them in the region are characterized.peer-reviewe
