The importance of weak social ties in professional commu- nities is well studied and widely accepted. In our paper we analyze the structure of strong ties based on the co-authorship relation and use the formal concept analysis framework to figure out weak ties. The research is motivated by fast growing need in cross-disciplinary research, which re- quires experts from different areas to understand the bigger picture and identify potential fellows for collaborative research projects in nearest future.
In this paper the assessment of the reliability of radiofrequency cords was carried out. The analysis of mathematical models of the failure rate assessment of components of the radiofrequency cords was submitted and the optimal model, combining incoming components, was deduced. It was concluded that during the calculation of the reliability of the radiofrequency cords, their models must take into account the maximum number of influencing factors in order to produce adequate results.
Сетевая активность университетов и её измерение
В статье описывается подход к созданию хранилища научных публикаций с поддержкой семантического индексирования на основе онтологического подхода, методов компьютерной лингвистики и обработки неструктурированных данных. В качестве инструментальной среды для обработки текстов используется платформа GATE. Для анализа публикаций используются специально разработанные онтологические ресурсы, описывающие структуру публикаций и их формат. Также при об- работке текстов используются словари ключевых слов и частотные характеристики текста. Реализация предлагаемого подхода позволит упростить поиск и анализ публикаций по заданной тематике, выявить связи между ними
Analytical communities for the goal of this paper can be defined as loosely united clusters of professionals doing joint or related work in policy analysis, research and development, who frequently work together on common analytical goals and clients, while not necessarily form a special organizational structure which differ them from think tank. Examples of analytical communities could be university research departments, regular authors of one analytical journal, members of certain intellectual clubs, or regularly meeting informal research groups, including individual intellectuals working together on the regular basis. The goal of this paper is to show an important connection between regional and local analytical communities and local administrations of the Russian regions to specify a unique role the analytical communities can play in strategic planning, providing local administrations both with data, ideas, solutions, and scenarios of social developments, which local authorities are interested to get the answers to.
To improve Wi-Fi performance in scenarios with high collision probability, recent amendments to the Wi- Fi standard introduce a number of channel access methods based on preliminary channel time reservations. A common feature of these methods is that channel time is reserved in a periodic manner. Unfortunately, having defined a number of channel reservation methods, the amendments say nothing on how much channel time shall be reserved to transmit a stream with required quality of service and minimal channel resource consumption. In this paper, we develop a mathematical model of streaming via periodic reservations which helps to answer this question.
The concept of “global governance” emerged as the focus of active scientific debates mainly after the studies of Willy Brandt and his colleagues from the UN Commission on global governance. This Commission was created to discuss possibilities for solution by joint efforts of such global problems as deterioration of environment, fight against poverty, infection diseases, etc. In 1995 the Commission prepared its Report “Our global neighborhood”. The Report justifies necessity of global governance by claiming that its development is an essential part of humans’ efforts towards rational organisation of life on Earth and this process will continue forever (Our Global Neighborhood...1995). The reason for creation of global governance arises from the conviction that humankind after the era of global wars and global confrontation has a unique opportunity for adoption of the “global civil ethics”, which should be founded on the package of fundamental values, uniting people of all cultural, political, religious and philosophic beliefs. Such governance should manifest democratic principles on every level and should be exercised according to the established legal norms, which should embrace everyone.
