The current stage of development of the sphere of telecommunications services is accompanied by a side effect - electromagnetic pollution. Until recently, the effects of hygienically significant levels of electromagnetic radiation (EMR) were subjected to only a certain number of people associated with professional activities. At the present time due to the powerful development of the telecommunications market in Russia is necessary to speak about the impact of EMR on the entire population. It should be noted that the growth of telecommunications services in Russia are far ahead of all forecasts. In this regard, there is an urgent need for monitoring the electromagnetic environment in the locations of radio transmission of technical objects.

One of the problems when storing large amounts of data is a rational choice of media. In this paper we evaluated the possibility of using magnetic tape, CD, DVD, Blu-ray discs, hard disk drives, drives to flash memory (SSD) for storage of large volumes of data with respect to reliability, performance,.cost and high-speed storage. The analysis showed that solid state drives can be used in case of the need for ultra-fast access to live data. The hard disk drive can be used as primary storage devices for storing operational data. DVD and Blu-ray library can be used for archival storage medium volumes (tens of terabytes). Tape libraries can be used to store very large volumes of data (terabytes or more). The lowest cost of storing 1 GB of data is $ 0.03 when you use tape libraries. The most expensive storage 1 GB solid state drive ($ 0.85).

Keywords: storage devices, data storage, storage drive

The article is about generators of random numbers (GPN) constructed on points of an elliptic curve and algorithms of development irreducible polynomials over prime fields. It describes their advantages and main features. The authors analyzes the algorithm of development GPN constructed on points of an elliptic curve with using irreducible polynomials of degree three over finite fields. In this approach, calculations were made in the system of residual classes. According to the results of computer simulation shows the advantages of algorithm in speed and security of a cryptosystem.

Keywords: the generator of pseudo-random numbers, elliptic curve, system of residual classes, cryptographic security, irreducible polynomials

The state of the atmospheric air in such industrial cities of the Rostov region, as Belaya Kalitva, Donetsk, Kamensk-Shakhtinsky over the last 10 years (2003-2012). Identified main pollution sources and priority pollutants. Analysis of the concentrations of pollutants in areas of concentration of industrial enterprises, on highways and in dwelling zones. It is established that industrial cities are specific «geochemical provinces», in which abnormally elevated concentrations of many chemical elements. On the background of the decrease of the role of industrial enterprises in the air pollution increases the role of motor transport

Considered original interpolation method of the working tool path using confluent two-unit manipulator. This method is based on the separation of the links on the master and slave and the use of polar coordinates to determine the incremental rotation of angle units. It is adapted for use calculating hardware with floating point.
