This paper is devoted to demonstrate by the example the adaptability of the Unified Modeling Language (UML) for formal description of structures of models, offered by cognitive psychologists. This approach is applied to the model of focused attention according to Broadbent’s hypothesis of attention. The paper illustrates that UML model of cognitive phenomenon can then be translated into working software simulator. Resulted data prove the adequacy of synthesized simulator of focused attention to known experimental data.

2. Automation of operational planning of work of a port warehouse of bulk cargoes [№3 за 2009 год]
Authors: А.V. Flegontov , Летуновский А.В.

The idea of perfection of processes of automation of management by an arrangement of cargoes in a longitudinal warehouse of bulk cargoes is described. Production a problem of minimization of the occupied area of a warehouse of bulk cargoes, which is considered on the certain time interval is given. The longitudinal type of storage is considered only.

3. Smooth interface of surfaces construction algorithm [№3 за 2009 год]
Authors: D.V. Kurennov, Partin A.S.

In article the description smooth interface of surfaces construction algorithm which is used at system development of geometrical modelling of machine-building details is offered. As the base the method of Beze for representation of curves and surfaces in parametrical sort is used. Feature of algorithm is reception of a portion of interface in analytically exact sort.

4. Stars selection algorithm for celestial orientation [№3 за 2009 год]
Authors: Кружилов И.С., O.Yu. Shamayeva

In the following article it is adduced math formulation of stars selection problem in astronavigation. It is given general description of stars selection method, which uses as basis criterion the constancy of mutual digression between the particles. It is substantiated the use of line model for analysis of changing the distance between 2 focuses.

5. Analysis of problems in design and implementation of information systems in high schools [№3 за 2009 год]
Author: Актаева А.У.

In the publication the urgency of designing of information-technological systems and features of their introduction in educational process contains. Functions and structure of information-technological system in educational process are described. The information maintenance of administrative activity of the chief of school constructed on creation of information systems enables to lower difficulties and to expand sphere of information use.

6. Analysis of the systems of treatment of information and control by means group fuzzy numbers [№3 за 2009 год]
Authors: Uskov A.A., Сургучева И.В., Горбунов А.М.

Group algebraic operations over fuzzy numbers – operations at which application indistinct numbers derivate abelian groups on addition and multiplication operations are offered. It is shown that application of group algebraic operations at fuzzy modeling, in some cases, allows receiving results better in good agreement with practice, than those which are received with application of traditional fuzzy numbers.

7. The generic algorithm for choosing the dominant signs for a neural network [№3 за 2009 год]
Author: Нигматуллина А.Н.

The problem of choosing the dominant signs for a neural network training selection forming is solved. For simplification the current problem the generic algorithm based approach is offered.

8. Boundary conditions of local problem in subgrid method [№3 за 2009 год]
Author: Мельниченко Н.С.
Visitors: 8297
The filtration problem for a viscous compressible multiphase fluid mixture in a porous medium is considered. A correct spatial discretization using subgrid method is discussed. Algorithm of method parameters choice is described. A flow approximation error for homogeneous isotropic case is estimated.

9. Dynamic change of processes based on Windows Workflow Foundation platform [№3 за 2009 год]
Authors: Маслаков М.А., V.N. Yakimov
Visitors: 9546
An approach to the creation of adaptive processes on the basis of a commercial platform for workflow-management Windows Workflow Foundation is proposed. The approach is based on the one of existing methods of workflow modeling, adapted in accordance with the features of the architecture and limitations of the platform. The description of the software components library developed for the creation of adaptable processes is presented.

10. Applying models of cooperative decision making in intellectual systems [№3 за 2009 год]
Authors: Сикулер Д.В., Fomin V.V.
Visitors: 15140
The article is devoted to questions of usage of models of cooperative decision making in automated intellectual systems. Applying of such models to pattern recognition is being considered. Recognition software based on models of cooperative decision making is being described.
