Reviews problems of developing the ontological approach-based incident management system (IMS) of decision support system for resolving incidents in information systems. It supports decision-making in variety of subject domains, for example, while training the service staff and system administrators, who are responsible for operation and management of complex information systems. In this case, the incident management system is based on the ontological approach and semiotic modeling. The semiotic model of subject domain under consideration is presented in the form of a graph, where graph vertices are interpreted as objects, and graph edges are interpreted as relations between them. The classification principles used in incident recording are proposed.
A GUIDE TO THE FUNDAMENTAL THEORY AND PRACTICE OF OPTICAL COMMUNICATION Fiber Optic and Atmospheric Optical Communication offers a much needed guide to characterizing and overcoming the drawbacks associated with optical communication links that suffer from various types of fading when optical signals with information traverse these wireless (atmospheric) or wired (fiber optic) channels. The authors--noted experts on the topic--present material that aids in predicting the capacity, data rate, spectral efficiency, and bit-error-rate associated with a channel that experiences fading. They review modulation techniques and methods of coding and decoding that are useful when implementing communications systems. The book also discusses how to model the channels, including treating distortion due to the various fading phenomena. Light waves and their similarity to radio waves are explored, and the way light propagates through the atmosphere, through materials, and through the boundary between two materials is explained. This important book: Characterizes principal optical sources and detectors, including descriptions of their advantages and disadvantages, to show how to design systems from start to finish Provides a new method of predicting and dealing with the dispersive properties of fiber optic cables and other optical guiding structures in order to increase data stream capacity Highlights effects of material and multimode (multi-ray) dispersion during propagation of optical signals with data through fiber optic channels Presents modulation techniques and methods of coding and decoding that are useful when implementing communications systems Written for professionals dealing with optical and electro-optical communications, Fiber Optic and Atmospheric Optical Communication explores the theory and practice of optical communication both when the optical signal is propagating through the atmosphere and when it is propagating through an optical fiber.

The research on technical regulations and standards highlights that the EAEU is already implementing many EU standards as the basis for reforming and modernizing its former GOST regulations and standards. In addition the EAEU is adopting many standards of the international standards organizations (ISO, IEC, ITU), which work very closely in partnership with the European standards organizations (CEN, CENELEC, ETSI), such that international and European standards are to a large degree identical. This means that the legal and technical infrastructure for non-tariff barriers of the two parties is already converging. This makes non-tariff barriers a potentially fertile field for cooperation between the EU and EAEU, which in turn could mean easier access to markets and increased mutual trade. In this case, the potential format and extent of cooperation could extend to include a Mutual Recognition Agreement (MRA) on Conformity Assessment, through to the most ambitious formula (in EU practice) of the Agreement on Conformity Assessment and Acceptance of Industrial Products (ACAA). Such arrangements would in principle ideally form part of a free trade agreement. Such scenarios can be technically specified, but of course they would have to rely on demanding political conditions which today are not satisfied.
