1. Analyze of fault tolerance for parallel circular computing system [№2 за 2010 год]

It inputted the notion of circular computing system model (CCS) (which represented in form non-orienteering circular coloring graph) and set of several identical that models (SCCS). Model of task for SCCS defined haw graph which is identical model of CCS. Destruction of CCS mean a selection any own subgraph in model (DCCS), and mending DCCS is addition of any vertexes and-or edges from CCS/DCCS. Failure of SCCS is inability to find isomorphic image of task model in any DCCS on SCCS. It is researching the possible of task entering on DSSC and depending that on color number and ring long. It is reasserting the depending mean time of first failure SCCS on parameters of graph CCS and increase low of SCCS by imitation modeling method

The variant of the error positions detecting algorithm for binary BCH-codes decoding is described. Proposed procedure, based on polynomial operations, is alternative to the Chen procedure and subsequent error bits inverting.

3. Intellectual tutoring based on the development and use of tutoring integrated expert systems [№2 за 2010 год]
Authors: Рыбина Г.В., Семенов А.В., Степанов Л.С., Нистратов О.В.

Description of the experience and perspectives of using tutoring integrated expert systems developed on the basis of task oriented methodology and benchwork AT-TECHNOLOGY (web version) supporting this methodology.

4. Use of ontology in forecasting business development [№2 за 2010 год]

The proposed approach the method of analysis of hierarchies, which consists of decomposing tasks info subtask and forecasting the further processing of the sequence of judgments of experts. In this case the object names and attribute names are considered as identifiers of tasks and the factors taken info account when formulating the forecast.

5. Calibration test tasks using bootstrap method [№2 за 2010 год]

The article substantiates the possibility of using bootstrap method for calibration of the test tasks. The basis of computer experiments shows that using this method can significantly reduce the size of interval estimates difficult tasks.

6. Mathematical model of controlled execution [№2 за 2010 год]
Author: Шмырев Н.В.

Formal description of a complex information systems should be able to describe the objects of a system and their interaction and should unify approaches to the description of calculations. In this article the model of the calculations describing the main aspects of controlled execution of distributed reliable realtime applications is presented

7. A blur detection method for digital images’ edges [№2 за 2010 год]
Author: Koltsov P.P.

The paper submits image blur estimation method, which is not based on a priori information on external conditions for image taking. The method based on previously introduced edge detector operator. This operator produces local approximation of the digital image’s fragments by some more easy function. The approximation is made with a step-form function in the round-form windows.

8. Modelling robot’s interaction with external environment on the basis of spatial logics and constraints propagation [№2 за 2010 год]

The evolution of robots generations is analyzed. The necessary requirements to develop 4th generation robots as cognitive agents are formulated. It is shown that an important property of cognitive agent is situative information granulation enabling the work under uncertainty. In the context of constructing spatial granules a static spatial logic is introduced to model robot’s interaction with external environment. It is based on combining Pospelov’s pseudophysical logics with Zadeh’s generalized constraints. Some versions of fuzzy linguistic constraints propagation for the problems of spatial situation analysis are investigated.

9. Modelling of three-dimensionnal temperature fields in electronic modules [№2 за 2010 год]
Authors: Madera A.G., Kandalov P.I.
Visitors: 13535
The article is dedicated to a method of mathematical and computer modeling of three-dimensional temperature fields in complex design of the real electronic modules, containing multilayer printed circuit board, installed integrated circuits and electroradio elements. The method is made as the program for personal computer

10. Modelling an emotional condition of the person on the basis of hybrid methods [№2 за 2010 год]
Authors: Розалиев В.Л., Заболеева-зотова А.В.
Visitors: 13781
Object of this work are emotions of the person. The primary goals of clause is a definition of the basic concepts, characteristics, functions from the theory of emotions and construction the mathematical model of emotion. The offered model has not only theoretical interest, but also a practical orientation.
