AUTOMATING THE PROCESS OF ESTABLISHING DATABASE ACTUALIZATION SERVICES
S.S. Alikin, Moscow Technical University of Communications and Informatics, post-graduate; email@example.com
The article describes the typical structure of a contact center, a classification of services provided by given contact center and an algorithm for establishing database actualization services. As a means to accelerate the establishment of such a service in the various models of contact centers that are structurally similar to the model referred to as typical, it is proposed to use a heuristic algorithm based on the expert system. The article defines stages of the algorithm, and a list of requirements that must be satisfied in order to reduce the establishment of services while maintaining quality of the result of its work.
Key words: contact center, service creation, relational database, database actualization, heuristic algorithm, expert system, fuzzy logic.

The letter deals with the problems control of the electromagnetic fields in modern cities. On the example of Moscow, a detailed analysis of the factors that determine the electromagnetic environment in the city and beyond. Clearly identified problems of the modern state of the problem of electromagnetic monitoring and ongoing ways to address, such as the development of regional regulations and methods, the development of fragments of geo-ecological mapping of the radiation sources and the fields they created, with reference to an electronic map of the city. The analysis revealed a critical situation for the population of the mega polis from the point of view of the impact generated by the considered networks of electromagnetic fields, and also identified areas for further work.
Keywords: electromagnetic fields, electromagnetic pollution, electromagnetic monitoring, electromagnetic prediction, geo-ecological mapping.

The paper is devoted to the analysis of the current state and the trends of the NFC-based services on transport in Russia. The presented results are based upon the research study performed for the Infocommunication Union. The paper is devoted to the detailed analysis of two important components of any NFC-based transport service: a transport application (applet) and the trusted service manager (TSM). The role and structure of the mentioned components are described and the recommendations are given. Furthermore, the article stresses the importance of the certification of the developed solutions as it allows for a seamless interaction of all components regardless of the particular implementation of the service. Finally, some tendencies in the development of transport services are outlined.
Key words: contactless payments, Near Field Communication (NFC), Trusted Service Manager (TSM), transport applications.

The article is devoted to the comparison of spectrum monitoring coverage features of AOA and TDOA geolocation methods. Advantages and disadvantages of such systems in monitoring networks containing different number of fixed monitoring stations that interact with mobile monitoring stations are shown. Recommendations are formulated concerning implementation of such systems in various conditions. Results of this work can provide the essential help to communication administrations under development of their monitoring networks taking into account that still there is no experience in the world concerning practical implementation of TDOA systems for needs of the terrestrial spectrum monitoring.
Keywords: spectrum monitoring, monitoring network, monitoring station, coverage by monitoring, direction finding, geolocation, АОА, TDOA
