Recommendations as part of the marketing of interactive television

Natalia Yashenkova

Abstract
Interactive television service at a certain stage of its evolution requires the appearance of additional services aimed at consumers. The recommendations allow the caller to provide ample opportunities for personalization of television service, as well as help to increase the profits of the operator. The system recommendations for a long time ceased to be a set of ratings, as marked by random users. Advisory service is a modern and complex of filters and algorithms, the main task of which is to most accurately predict the possible choice of the subscriber.

Iidel of signals reflected from the earth’s surface sections in the process of its locations by radar sensor with low angular resolution

Afanaciev V.P., MTUCI

Abstract
The reflective properties of the earth’s surface sections with radar location are proposed to describe as a model in the form of the quasideterministic random field. The effectiveness of the approach is discussed on the example of the classification of the earth’s surface sections if using radar sensor with low angular resolution. The model of the observations in this case is a quasideterministic random process.

Keywords: radio locator, resolution in range, surface element, desired signal, echo signal.

Abstract
Procedures for the digital filter response with limited dimension filter considered for application to problems in the construction of medical devices such as “ECG”, “EMG”, “EEG”, etc. The emphasis is on clarity, change “spectrum, frequency response, the response of the convolution” of the underlying digital filtering. The question of the choice of sample rate unaffected. We investigate the transition process of filtration. The concept of “additional filter” is introduced that makes it easy to find the parameters of “HPF”. All that is necessary to facilitate the engineering construction of filters with priimeneniem modern computing packages of programs.

Wireless networks of new generation WiMax and LTE: the productivity analysis at application on transport

Legkov K.E., Moscow Technical University of Communications and Informatics (MTUCI)

Abstract
Now the most widespread technology of wireless access which is everywhere applied to transfer of a considerable quantity of the traffic of a various kind, the standard of wireless local networks IEEE 802.11 is. Networks of so-called standard IEEE 802.11n became one of the most perspective directions of development of technology Wi-Fi. At the expense of application of technologies MIMO possibility increase of channel speed in a network of the given standard is defined. However, the further development of wireless technologies has brought in our life some more perspective standards: the standard of wireless networks of city scale IEEE 802.16 and new standard LTE, the successor of cellular networks of standard HSPDA. Having inherited classical architecture of cellular networks, LTE has got the high throughput exceeding those even of current generation 802.16е. Modern Russian transport is in a modernization stage that is absolutely necessary for increase of safety and efficiency of transportations. For achievement of it the modern system capable automatically to operate available resources is required and operatively to make decisions at corresponding level. Working capacity of the given system will be defined by quality of operating-technical communication on transport. The important key question of a choice of the most qualitative technology with the raised productivity for application on transport also is considered by the author in article.

Keywords: Wireless systems, the standard, a range of frequencies, the terminal, the channel.

Khlopov B.V., TSNIRTI Academician AI Berg, Ph.D., corresponding member of the Academy of Natural Sciences, hlopovu@yandex.ru

Abstraсt

Methods for the analysis of deleting of the information from magnetic carriers by visualization of separate fragments of magnetic disks are considered. The most perspective method providing change of a magnetic condition of a thin-film layer of a magnetic data carrier with simultaneous visualization is defined. It is shown that magnetooptical methods of visualization of magnetic fields allow to reach the high permission. They don’t destroy magnetic structure of data carriers. Allow to observe a magnetic relief of a surface of a disk. The conducted researches have allowed to formulate requirements to sizes of magnetic fields necessary for effective magnetic reversal of thin-film layers of data carriers and deleting of the information written down on them. On the basis of these requirements the equipment is developed for change of a magnetic condition of a thin-film layer of a magnetic data carrier. The equipment registers a magnetic relief of record, and also change of a magnetic condition of a thin-film layer of a magnetic data carrier before deleting of the information and after deleting, with an external pulse magnetic field and provides visual supervision of fragments of a magnetic relief on any site of a magnetic data carrier, automatically magnetic relief of record on a thin-film magnetic plate of a magnetic data carrier transforms to the electropotential relief corresponding to spatial distribution of intensity of a magnetic field on a surface of a magnetic data carrier. The equipment small-sized also takes place directly in the system block of the personal computer. The qualitative visual analysis of a condition of magnetic disks after deleting of the information by devices of other manufacturers allows to move.

Keywords: Visual control, the magnetic field, scanning probe microscopy, a data carrier, a magnetic disk, a magnetic relief, information deleting, intensity of a magnetic field.

ON THE ADVANTEGES OF INFORMATION SYSTEMS BUILT ON VIRTUAL INSTRUMENTS WHEN MEASURING THE PARAMETERS OF MOBILE RADIO COMMUNICATION

Kubankov A.N., Lorey N.A., Moscow Technical University of Communications and Informatics (MTUCI)

Abstracts

The need for measuring the parameters of mobile radio communication (MPMRC) occurs firstly, in the final stage of production when it is necessary to check the compliance of output with the approved product specifications, secondly, in the process of radio station operation when the assurance of full operational capability is needed before the implementation, and thirdly, during the routine maintenance or preventive repair. The efficiency of mobile radio communications characterizes their ability to transmit information with the setup parameters. The work reviews approaches to MPMRC. It is shown that means of MPMRC are built on the basis of the conventional instrumental engineering solutions. The advantages and disadvantages of each approach are identified. Their common feature is that they are obsolete, since they do not provide a proper degree of automation of performed operations related to the parameter verification and control; do not allow to carry out the entire class of measuring tasks required. However, the approach to MPMRC is possible if based on modern measuring and computer technologies, in particular, using the technology of virtual instruments.

Keywords: parameters of mobile radio communication, virtual instruments, information and measuring system, measurement, functionability.
