RESEARCH OF ABUSE ABILITIES IN DECENTRALIZED NETWORKS WITH REWARD DISTRIBUTION

The problem of abuse by community of free-ride users in decentralized networks with reward distribution is considered. Various structures for organizing nodes of a decentralized network belonging to the community of free-ride users, which can be used to obtain the greatest benefit in reward distributing in the network, are proposed. To compare the proposed structures, simulation of reward distribution was used. After analyzing the results of experiments, it was concluded that combining the nodes belonging to community of free-ride users into a structure of the “Generalized Ring” type with a sufficiently large number of nodes gives the best results from all the proposed structures.Key words: decentralized networks, P2P, abuse, free-ride users, reward distribution, author, subscriber.Анищенко К.М.; кандидат технических наук, доцент, Жданова Е.Г.; Скорик В.А., кандидат технических наук, доцент, Сперкач М.О., Исследование возможностей злоупотреблений в децентрализованных сетях с распределением награды/ Национальный технический университет Украины «Киевский политехнический институт имени Игоря Сикорского», Украина, г. КиевРассмотрена проблема злоупотреблений со стороны сообщества free-ride пользователей в децентрализованных сетях с распределением награды. Предложены разные структуры организации узлов децентрализованной сети, принадлежащих сообществу free-ride пользователей, которые могут быть использованы с целью получения наибольшей выгоды при распределении наград в сети. Для сравнения предложенных структур было проведено моделирование распределения наград. В результате анализа результатов экспериментов сделано выводы о том, что объединение узлов, принадлежащих сообществу free-ride пользователей в структуру типа «Обобщенное кольцо» при достаточно большом количестве узлов дает наилучшие результаты из всех предложенных структур.Ключевые слова: децентрализованные сети, P2P, злоупотребления, free-ride пользователи, распределение наград, автор, подписчик

Influence of air Gap Between the Transformer of Resistance and Object of Monitoring on Temperature Measurement Error

In operation the description of the developed heattransfer model in thermotransformers of resistance (RTD) in the conditions of air gap between surfaces of the sensor and object of measurement is provided. Research of influence of thickness of air gap on the relative error of temperature measurement by platinum, copper and nickel thermotransformers of resistance in the ranges of temperatures corresponding to each type is executed. Dependences of minimum necessary duration of heating up of sensors on the taken temperatures are received

Mobile Health Intervention for Outpatient Treatment of Tuberculosis and HIV Infection

Aim of the study. To describe the results of using mobile health intervention for improving the compliance of patients with tuberculosis and HIV (TB/HIV). Materials and methods. Piloted clinic-affiliated mobile intervention was carried out in 54 patients with TB/HIV and with a history of psychoactive substances abuse in Irkutsk Regional Clinical Tuberculosis Hospital. The mobile intervention included a smartphone application that connected the participants to the staff of Irkutsk Regional TB Hospital and provided daily queries on stress, mood and medication adherence; appointment reminders; virtual support group and consultation resources; weekly quizzes. We assessed longitudinal impact on retention in medical care, visit constancy, viral loads and CD4 counts, TB outcomes. Results. In 6 months, we registered the increase (in comparison with baseline) in mean CD4 counts (F = 6.61; р = 0.04) and in the number of cases of suppressed viral loads – from 20.5 % (9/44) to 55.3 % (21/38) (p < 0.01) in TB/HIV users of e-health app. We found a lower level of TB treatment interruption in patients who used the application in comparison with the patients who refused to use it (4/44 vs 5/10; χ2 = 7.09; р = 0.008). App users completed the course of TB treatment in 63.6 % of cases (28/44), and 61.4 % of patients (27/44) were cured which was higher than the level in the control group (20 % (2/10)) (χ2 = 7.54; p = 0.03). Conclusion. This study has demonstrated that a mobile health intervention can have a positive impact on improving the medical and social care and clinical outcomes for TB/HIV patients with history of psychoactive substances abuse

Student youth participation in the development of a comfortable urban environment

Currently, the problem of youth participation in the development of urban space is extremely relevant both from the perspective of transforming the living environment with the resources of local communities, and the socialization of urban youth itself, expanding opportunities for personal growth through involvement in socially useful activities. The purpose of the article is to identify the conditions and readiness to participate in the development of a comfortable urban environment for students. The study was conducted in Vologda, Russian Federation, through a quantitative methodological strategy (questionnaire survey among university students, n = 207). The paper presents theoretical and methodological approaches to understanding the urban environment and a comfortable urban environment. It is indicated that a comfortable urban environment is a socio-economic category, reflecting the interactions within the urban space, which is most comfortable for the life of citizens. It is concluded that the student youth expresses their willingness to actively participate in decision-making on the development and improvement of the urban environment. In conclusion, the directions of enhancing the civic participation of young people in the formation of a comfortable urban space on the basis of dialogue platforms are considered

ИССЛЕДОВАНИЕ ЗАВИСИМОСТИ КРИСТАЛЛОГЕННОЙ АКТИВНОСТИ БИОСРЕДЫ ОТ ИНТЕНСИВНОСТИ ЭКСПЕРИМЕНТАЛЬНОЙ ИНВАЗИИ Trichinella spiralis

Urine dehydration structurization at experimental trichinellosis of rats is studied. In 4 weeks after exposure rats urine was analyzed with biocrystallomics methods. It was stated, that urine crystallogenic properties changes according to intensity of infection.Изучена дегидратационная структуризация мочи крыс при экспериментальном заражении их Trichinella spiralis. Кристаллогенную и инициирующую активность мочи животных исследовали методом тезиокристаллоскопии через 4 недели после заражения. Исследование кристаллогенных свойств и инициаторного потенциала биологических жидкостей организма может стать индикатором наличия и глубины метаболических сдвигов, вызванных гельминтами

Optimization criteria for entry into the consolidated group of taxpayers in order to create an effective tax mechanism and improve the social, economic development of regions in the Russian Federation

This article discusses the existing socio-economic development of regions. The social and economic development of the regions is directly affected by the tax ratio and mechanisms of their functioning, which are the subject of study for both foreign and Russian economists, as the state regulation of any economy is possible through tax relations between parties. In 2012, there was established the taxation of consolidated groups of taxpayers, which exists in many countries and provides payment of income taxes based on the total financial and business performance of the group. However, in our opinion, the requirements for entry into the group are much too high. The article presents a method that allows analyzing the changes in the number of potential participants of a consolidated group of taxpayers depending on the changes in the threshold of entry using indicators. These indicators can be based on the aggregate value of assets, or represented in terms of total revenue or the amount of taxes paid. The reduction in the existing criteria will optimize tax administration of the major taxpayers and more evenly redistribute financial flows between regions of Russia
