31. Boundary conditions of local problem in subgrid method [№3 за 2009 год]
Author: Мельниченко Н.С.
Visitors: 8303
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.

32. Cad for automated cost-effective plant layout design [№3 за 2009 год]
Authors: Meshalkin V.P, Образцов А.А., S.V. Panchenko

The chemical plant design is the complex engineering problems which includes two stages – the equipment layout and piping design. The optimal approach to this problem makes it possible to solve the resource and energy saving problems and get the cost-effective and eco-friendly project solutions. The architecture of CAD for automated optimal plant layout design and the results of equipment layout and piping design of reforming plant for ammonia synthesis are presented in the article.

33. 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.

34. Knowledge structurization of control system scheme designing process [№3 за 2009 год]
Author: O.L. Akhremchik
Visitors: 11847
Development of the structurization concept of knowledge in the field of designing of systems technological objects is offered. The program system is considered as the expert which is carrying out synthesis of a number of descriptions of designing object at different abstraction levels. The volume of formal concepts is carried out through the properties represented in quality and quantity scales. The composite relation group between abstract and real elements is allocated.

35. Method of an estimation of probability of acceptance of erroneous decisions at the discriminant analysis of transport knots [№3 за 2009 год]
Author: Пасевич В..
Visitors: 11381
Using diskriminants models in transport nodes, it is sufficiently often bring about wrong decisions. So finding to probability such mistakes exceedingly it is important, to term of the tense motion and manoeuvre of the transport units particularly. The method finding happens in work to probability such mistake and their estimations.

36. Making a knowledge model of technologies by means of discriminant algorithms [№3 за 2009 год]
Author: Пименов В.И.
Visitors: 10099
Features of representation in computer training systems of technological knowledge which describe the processes directed on manufacture of a material or information product are considered. The approach based on allocation of classes is offered.

37. Accelerated preference formalization algorithm for decision support [№3 за 2009 год]
Author: Портоне Д.С.
Visitors: 11331
In the article it is suggested to use the method of preference formalization for construction of rankings. This method is based on combination of traditional methods of vector criterion scalarization (a method of the weighed sum and a method of an ideal point) and the method of preferences, which was implemented in decision support system DSS/UTES.

38. «ASKON» software system use practice [№3 за 2009 год]
Authors: Родионов Л.Ф., Уютов А.А., Назарова И.А.
Visitors: 15506
«ASKON» company software products (KOMPAS – Autoproject, Vertikal) are widely used at machine building plants. In the process of using a set of questions arises, which you can solve through the data base update and edit.

39. Web-server information security improvement with techniques of protection from investigation [№3 за 2009 год]
Authors: Semenkin E.S., Стюгин М.А.
Visitors: 11018
The approach to information security improvement based on informational control of the violator is considered. The algorithm of the technology of systems protection from investigation is presented. The approach is illustrated with two examples of technology implementation for web-server protection from aforethought attacks.

40. Applying models of cooperative decision making in intellectual systems [№3 за 2009 год]
Authors: Сикулер Д.В., Fomin V.V.
Visitors: 15141
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.
