Researches of electric processes in a single-wire line and in the flat condenser

In TV systems carry out digitization of initial signals of images in all directions of a multidimensional video information field: horizontal and vertical within separate shots, colour and time directions within sequence of shots. Thus it is necessary to provide effective interface of anisotropy spectr signals of images and digitization structures.
Principal causes of occurrence of the nonlinear distortions accompanying realisation of digitization video information signals are considered. Variants of structures of digitization with uniform distribution of pixels within intrapersonnel space are presented. The technique of realisation of the comparative analysis of characteristics of their two dimensional spectrum is developed. The settlement parities providing a basis for comparison purposes and a choice of parametres of structures of intrapersonnel digitization at designing of systems of digital TV of different function are received.

yearly growth amounted 53%. In 2007 Internet penetration
level was 8%, by the end of 2008, it increased by
1% up to 9%.
By the end of 2008, the subscriber base of Residential
and Corporate Broadband in the Central Asian countries

with the other three countries have 18% of the total
Broadband subscribers in the region.
In 2007 the revenues in the region reached $148 mln.,
with a 140% growth. By the end of 2008 the Broadband
revenue reached $175 mln., while the revenue growth
rate was 18%. This tendency emerged due to the world
financial crisis.

Their total share in general household energy consumption has exceeded fifteen percent and keeps going up. Forecasts of the International energy agency (IEA) and the review of technology of energy consumption reduction “Least Life-cycle Cost” (LLCC) are presented. Possible ways of the answering machines terminal equipment energy consumption reduction are shown as an example. Power efficiency of the methods and the estimation of a speech transmission quality in answering machines were investigated. Ways of energy consumption reduction are divided into two groups one of which does not cause listening difficulty of the information by subscribers and another does.

The world wide clear trend from traditional toll collection towards open road tolling systems

Abstract

As announced Vice-Premier Sergei Ivanov, Russia wants to make its highways to tollable. For trucks above twelve tons of a road user fee will be required. The Economics Ministry expects some 1.5 billion euro revenue. It stated that the Transport Ministry has already prepared a tender for the establishment of a toll collection system. The system is to monitor the movements of the truck, to ensure later an accurate collection and billing of the toll.

Tasks of image recognition of subsurface radar device based on mobile road laboratory

Zamotaiylov O.V.

Abstract

In this paper algorithms for subsurface radar data processing based on the GPR OKO2. In an analysis of the standard software GeoScan32 revealed a number of disadvantages. In this regard, developed a process chain, which allows with required frequency simultaneously obtain a digital image of a fragment of the pavement, GPS-coordinates and GPR signal OKO2 from the antenna. The developed software includes a set of programs GeoControl, allowing to correctly bind GPS-coordinates to the profile measurements, to recover the layers of pavement on the basis of these measurements, and in automatic regime to identify areas of non-uniform profile. Thus, in real time according to the established regime running the laptop generates information about pavement canvas of different nature, which continue to be used for statistical analysis and automatic recognition.

Keywords: subsurface radar, ground penetrating radar, pattern recognition, software.

Mathematical model for performance evaluation of physical security system

Lyeus A.V.

Abstract

The current state of high-security objects safeguarding problem is governed by variety of factors, including application of technical safety systems. On the other hand efficiency of such systems is often determined based on expert opinions rather than precise analysis. In this paper we present a mathematical model of physical security system, which can be used to estimate intruder detection probability and possibility of suppressing his actions. This model enables one to perform an objective analysis of the system’s efficiency of solving problems that it is designed to face.

Keywords: performance, mathematical model, security system, intruder movement model, penetration time, detection probability, detection area.

Wireless local networks IEEE 802.11: distribution of speeds mechanism

Low quality of communication on any direction of wireless local area network communication under control of IEEE 802.11 protocol with the distributed mechanism of access to a transmission medium influences all remaining corresponding pairs of nodes and on the whole network. The reason of it is in time reduction of channel occupation by stations using high speed of transmission at the expense of increasing time of channel occupation by stations transferring packets at low speed.

Characteristics of the data flows generated by a Web-server

Web servers generate the major part of the Internet traffic. Knowledge of the Web traffic structure is necessary in order to support the quality of service effectively. Containing data of various types and volumes file servers constitute a significant part of resources in a network. This paper describes the traffic of Web server providing access to the musical content. Analysis of data traces shows that generated by Web server traffic can be separated onto several data flows, based on a distribution of file sizes, requested by user. The main characteristics of these flows such as a number of arrived requests and a volume of transferred data from server considerably differ for various data flows.

Keywords: Web server, distribution of file sizes, TCP session, data flows, network traffic analysis.

In article results of research of noise stability in a communication channel in the presence of a casual interfering signal and several spread-spectrum signals are resulted. Various ratios on power between transferred signals are considered. In communication channel model quantization and discretization are considered. Calculation of an error ratio is made on the basis of model which is set in the form of mathematical expressions in program MathCAD. The considered way of transfer is intended for protection of the transferred information.
