11. Parallel adaptive preconditioner CPR concerning to the flow problem [№3 за 2009 год]
Author: Горелов И.Г.
Visitors: 6544
The adaptive modification of Constrained Pressure Residual method of preconditioning are considered concerning to the systems that appears from discretization of systems of partial differential equations which describes multicomponent fluid flow in porous media. The numerical experiments using real parallel hydrodynamic simulator on the real oil fields in Western Siberia demonstrated efficiency of the method.

The article considers forecasting problems of the regional information network characteristics subject to socioeconomic factors of user environment dynamic. The medium-term forecasting method for network elements traffic characteristics is proposed. The method is based on system-dynamic modeling of network technical parameters and user environment socioeconomic factors.

In article methodological bases of the decision of a problem of a rational choice of electronic components of foreign manufacture for creation of highly reliable domestic radio-electronic equipment are stated.

17. Program of disease diagnostics [№3 за 2009 год]
Authors: Жмудяк Л.М., Жмудяк А.Л.
Visitors: 17279
There was developed a methodic of diagnostics based on computation of diseases probabilities. This methodic is using multivariate distribution, repeatedly defined symptoms, analyses and other data, markers of viral hepatitis, etc – are considered. There was written a program that makes differential diagnostics between obstructive and hepatocellular jaundice with effectiveness 97 %.

18. Parallelization of cfd computations using block-structured grids [№3 за 2009 год]
Authors: Смирнов Е.М., Зайцев Д.К., Якубов С.А.
Visitors: 14811
We discuss some features of effective usage of the MPI technology to solve resource-demanding CFD problems on cluster systems using block-structured computational grids. Recommendations are given for arrangement of the inter-process data exchange to increase the parallelization efficiency.

19. System for models of the material reconstruction from images [№3 за 2009 год]
Authors: Ильин А.А., Игнатенко А.В.

Polygonal models of the objects from the real world often are used in virtual reality scenes. A lot of methods for creation and reconstruction of polygonal models are available nowadays. The acquisition of complex realistic models of the reflectance properties of materials and their photorealistic interactive rendering are still important problems in the computer graphics. In this work we focus on the process of the acquisition of the complex realistic models of reflectance properties of the material of the real world objects from their photographs.

20. Estimation of results of clusterization at usage of various criteria of quality [№3 за 2009 год]
Author: Киреев В.С.
Visitors: 15963
In given article quality of cluster solutions of a method of k-averages in sense of various criteria on a practical example is researched; the received results are compared to results of a method of the «pocket» clusterization offered earlier by the author, the superiority of this method is shown. On an example of one of clusters the practical difference as clusterization on structure of objects of clusters is estimated.
