Influential members in community lifecycle within social network
P. 78-81.
Sazontyev V. V.
This research aims to extend my previous work that analyzed community lifecycle within social network Vkontakte. One of serious problems of that work was inability to analyze whole graph, since Vkontakte’s API do not allow to download all network in a reasonable time, thus you are restricted with number of requests per second. This paper discuss main achievements of that work and propose one method that should be included in that kind of researches and should help to make more precise conclusions.

Резкий рост объема получаемых в эксперименте данных напрямую связан с модернизацией и развитием экспериментальной базы фундаментальных исследований. Прежде всего это относится к физическим, астрономическим и космическим исследованиям. В работе прослеживается история решения проблемы хранения и обработки экспериментальных данных, получаемых на радиоастрономических комплексах Пущинской радиоастрономической обсерватории, от РС и локальных файловых серверов к специализированным и распределенным ...

High-energy physics experiments rely on reconstruction of the trajectories of particles produced at the interaction point. This is a challenging task, especially in the high track multiplicity environment generated by p-p collisions at the LHC energies. A typical event includes hundreds of signal examples (interesting decays) and a significant amount of noise (uninteresting examples). This ...

The new technology used for data processing of population census results is described. The system was recently launched by Rosstat for 2002 and 2010 censuses. It gives the user an opportunity of on-line tabulation any demographic table from micro data with no need to download the data themselves and to set up any software. The ...

Long-term measurements of bottom pressure variations obtained in 4 experimental campaigns near Sakhalin Island (Cape Svobodny) are analyzed. The statistical characteristics of 20-minute records of sea surface displacements reconstructed in the hydrostatic approximation, as well as individual wave parameters, such as wave height, period, and wave asymmetry, are studied. Records with similar meteorological conditions are sorted according to ...

In this paper, we present a new Python library called mPyPl, which is intended to simplify complex data processing tasks using functional approach. This library defines operations on lazy data streams of named dictionaries represented as generators (so-called multi-field datastreams), and allows enriching those data streams with more 'fields' in the process of data preparation ...

Зачастую именно человеческий фактор ведет к распространению угроз на предприятиях. Если техническое устройство представляет собой четко работающий и слаженный механизм с возможностью при помощи диагностического оборудования проводить замеры параметров неисправностей и устранять их, то для исследования скрытых атак необходим новый компонент системы. Предприятия и промышленность в целом нуждаются в интеллектуальной системе защиты и обнаружения скрытых ...

Recent statistics report that more than 3.7 million new cases of cancer occur in Europe yearly, and the disease accounts for approximately 20% of all deaths. High-throughput screening of cancer cell cultures has dominated the search for novel, effective anticancer therapies in the past decades. Recently, functional assays with patient-derived ex vivo 3D cell culture ...
