The current state of data transmission channels from Pushchino to Moscow and perspectives
Since the work of a unique space radio telescope in the international VLBI project
"Radioastron" extended to 2017 the transmission and storage of large volumes
of scientific and telemetry data obtained during the experiments is still remains actual.
This project is carried out by the Astro Space Center of Lebedev Physical Institute in Moscow, Russia.
It requires us to maintain in operating state the high-speed link to merge into a single LAN
buffer data center in Puschino and scientific information center in Moscow.
Still relevant the chanal equipment monitoring system, and storage systems, as well as
the timely replacement of hardware and software upgrades, backups, and documentation
of the network infrastructure.
The publication contains materials of the conference dedicated scientific-technical problems in the field of Radioelectronics, telecommunications and computer engineering.
The publication is intended for researchers, engineers and graduate students.
The article suggests and describes a laboratory stand, allowing analysis printed board assembly electronic equipment (low-frequency amplifier) with the aim of monitoring the technical condition and diagnosis. This method has been implemented stand "Troubleshooting Handbook." The stand is designed for laboratory work by students in the course "means and methods of technical diagnostics."
Issues of ex post evaluation of mergers and antitrust bodies prescriptions are discussed. Among them: interrelation of enactment and enforcement from the perspectives of errors of I and II types in antitrust mergers control; probable consequences of mergers for competition; Аннотации к статьям 206 тьям № 1, 2012 comparative advantages and failures of decision variants available for antitrust bodies; ways of decision-making in expected merger. Also there are issues on efficacy of antimonopoly body decisions taking into account cost of monitoring, sanctioning of mergers participants, including influence on competition condition on relevant markets.
ICUMT is an annual international congress providing an open forum for researchers, engineers, network planners and service providers targeted on newly emerging algorithms, systems, standards, services, and applications, bringing together leading international players in telecommunications, control systems, automation and robotics. The event is positioned as a major international annual congress for the presentation of original and fundamental research and engineering results.
The system of statistical monitoring in the sphere of education, that was formed within previous years and met well the requirements of the centralized state planning and governance, but it appeared to be outdated in the post-perestroika years and could not adjust to innovative and rapid changes corresponded. For many years HSE Institute for Statistical Studies and Economics of Knowledge has been actively developing scientific and methodology base for information support to education policy-making. One of the most important areas of its activity is modernization of educational statistics. This article covers the evolution of educational statistics methodology in the post-soviet period, as well as recent novelties and key challenges that researchers and statisticians - past, present and future are facing.
The article suggests the integration of a neural network as a parallel element base in a telecommunication system. In this case, the ability to learn or adapt to external conditions is applied as the main advantage. For telecommunication systems in conditions when it is possible, this ability will improve noise immunity, reliability, operability, etc. The article considers an example of the integration of a neural network into a discrete matched signal filter. It is noted that the use of parallel mathematical methods in signal processing leads to the maximum effect of increasing the quality parameters of such telecommunication elements
In this paper the authors analyze the optimization of public service delivery in Russia. The role of the optimization of administrative processes in the modernization of public administration is also considered; major activities aimed at the optimization of the public services delivery in 2010-2011 are described; some background information for decision making process is revealed; major methods of improving quality and accessibility of public services are analyzed; the key methodological approaches for the reengineering of public services and spheres of government regulations are presented. Basing on the researches conducted, the authors propose the ways of making the activities aimed at the optimization of public services effi cient.
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traﬃc is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the ﬁnal node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a ﬁnite-dimensional system of diﬀerential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of diﬀerential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
Existing approaches suggest that IT strategy should be a reflection of business strategy. However, actually organisations do not often follow business strategy even if it is formally declared. In these conditions, IT strategy can be viewed not as a plan, but as an organisational shared view on the role of information systems. This approach generally reflects only a top-down perspective of IT strategy. So, it can be supplemented by a strategic behaviour pattern (i.e., more or less standard response to a changes that is formed as result of previous experience) to implement bottom-up approach. Two components that can help to establish effective reaction regarding new initiatives in IT are proposed here: model of IT-related decision making, and efficiency measurement metric to estimate maturity of business processes and appropriate IT. Usage of proposed tools is demonstrated in practical cases.
