The method of economical effectiveness analysis of broadband wireless access network construction is submitted. The analysis is based at technical effectiveness – power, frequency and information effectiveness. Influence of radiointerface parameters on capital and operational expenses of network is illustrated. Actual example of analysis of effectiveness of alternative of network construction.

13. Technicoeconomic optimization of construction and maintenance of mobile wimax networks [№4 за 2009 год]

The principle of a choice business of model of construction and operation WiMAX of a network is considered, the variant of construction wireless WiMAX is offered a network with application of wholesale model.

14. Scalar function algorithm minimization of many variables with interval limitation on variables [№4 за 2009 год]
Authors: Бояринов Ю.Г., Dli M.I.

The article deals with the search scalar function algorithm minimization of many variables with implicit function and interval limitation on variables. The main idea of algorithm, that the least value the function takes at one of the hypeparallelepiped apexes – the area of possible values argument, is in successive bypass of apexes from the initial point to the function decrease. The program algorithm realization is suggested in the MATLAB sphere.

15. Range possible value probability stay estimation in the given condition of markov’s productive and economic model [№4 за 2009 год]

The article deals with the finding of range possible value probability stay estimation in the given condition of Markov’s productive and economic model with an interval uncertainty about stream intensities events. Solution is found with the help of Kolmogorov’s equation and matrix algebra apparatus. The illustrating example is given.

16. Perturbation functions in geometric modeling [№4 за 2009 год]

Transformations of a geometric objects are described for set-theoretic operations, projections, offsetting, and metamorphosis. A binary relation such as collision detection is also described. This approach supports combinations of representational styles, including constructive geometry, sweeping, twisting, deformable and other animated objects. Interactive modification of the function model with fast visualization lets us provide both the interactivity and any required level of detail leading to photo-realistic appearance of the resulting shapes.

17. Topology and resistance of local-world networks [№4 за 2009 год]
Authors: Гаджиев Б.Р., Гибина Е.Ю., Прогулова Т.Б., Щетинина Д.П.
Visitors: 10937
The topology and the resistance of local-world networks are investigated. Different strategies of the local-world forming are analyzed. The degree distribution and the correlation type in considered networks are defined. The resistance of local-world networks to random failures and targeted attacks is considered. Keywords: complex networks, scale-free networks, local-world networks, degree distribution, correlated networks, random failures, targeted attacks, resistance of networks.

18. Automatized rating assessment system of student’s knowledge [№4 за 2009 год]
Author: Герова Н.В.
Visitors: 25141
This article deals with the issue of the application of rating assessment system in terms of modular teaching of the Boulogne system. It describes the automatized rating system of assessment of student’s knowledge. The article investigates the realization of basic functions within the information system.

19. The software of information-control system drying installation [№4 за 2009 год]
Author: A.N. Gribkov
Visitors: 11997
Questions of the software development of information-control system of drying installation with use CASE-technologies are considered.

20. Restful grid: using RESTful web-services in grid [№4 за 2009 год]
Authors: Демичев А.П., Крюков А.П., Шамардин Л.В.
Visitors: 24030
In this work we discuss the REST architecture for building grid services as an alternative implementation. Methods for creating grid resources, managing resources life cycle, error handling and information integrity are described and proposed as a standard for RESTful grid services. Advantages and weaknesses of such approach are discussed compared to traditional WSRF grid services.
