In this paper we study fundamental characteristics of P2P streaming system in order to find optimal rates, which can provide stable performance for a small system. This model accounts for peer churn, heterogeneity of upload capacities and it also calculates maximum available video rate for each parameter set.

The article deals with the analysis of the various automated information systems of higher educational institutions and approaches for their construction. The structure and a complex of solved problems by means of automation of educational process management is considered. In article settled requirements for automated information system of high school according to the Bologna education system and taking into account new system of a payment of the faculty of high schools.

5. The mathematical model for calculation of volume of a curvilinear site a highway [№1 за 2010 год]

It is offered to reduce losses of speed of control system based on the system of typical condition-action rules by means of a discrete-logic regulator. The comparative analysis of discrete-logic regulators’ speed is carried out. It is shown, that the discrete-logic regulator surpasses more than 4 times a regulator based on the system of typical condition-action rules, in speed.

7. Management of educational process [№1 за 2010 год]
Authors: Анциферова В.И., Сербулов Ю.С., Зольников В.К.
Visitors: 14581
In clause the model of management of educational process at the resource centre is considered.

8. The automated training system of technical diagnostics [№1 за 2010 год]
Author: Баин А.М.

The automated training system intended for improvement of professional skill of attendants of the enterprises and training of students in the field of technical diagnostics is developed. The system assumes use of three technologies of training: inductive, deductive and abductive. Results of experimental researches have shown that intensity of delivery of control actions has increased, progress has improved.

9. Complex automation system of process planning [№1 за 2010 год]
Author: Байбаков С.В.

In this article complex automation system of process planning were reviewed. It is a CAM system, designed in Technology of Oil and Gas Machine Building department of Gubkin Russian State University. The system is open user-loyal system which gives ability of designing technological processes using different methods, analyzing designing results, creating and using databases and so on.

10. Analytical and numerical investigation of discrete structures evolution algorithms [№1 за 2010 год]
Authors: Белов А.Н., Масюков В.В.
Visitors: 8619
New algorithms for discrete structures evolution modeling are proposed and under analytical and numerical investigation in a new program EVOLDIST. Numerical tests show that this technique is appropriate for very complex non-linear natural phenomena simulation.
