Approach to hydrodynamic models automatic construction is suggested. The approach is developed for hydrodynamic models construction support expert system. Aim of the approach is construction of mathematical model of arbitrary hydrodynamic system in form of differential equations system. Construction of hydrodynamic system qualitative model and qualitative model ontology are described.

The method of innovation activity planning problem solving is considered. On the base of problem features is made a conclusion, that problem should be solved as optimization problem. To consider the problem as a mathematical optimization problem, a definition of «innovative capability» term is given. An indicator for innovative capability estimation is suggested. On the basis of results obtained, verbal and formal statements of innovation activity planning problem is made. The method of problem solving based on stochastic search method modification is suggested.

34. An extensible model of edited multimedia document [№4 за 2011 год]
Authors: Большакова Е.И., Январев В.И.
Visitors: 8085
The paper reviews approaches to design multimedia document models and proposes a new model that combines the extensibility of visual object types and the possibility to conjoin objects of various types within the document page to be edited. The system Fuzzle CMS developed on the proposed model and intended for web sites management is described.

35. Research overfitting of recognizing procedures on the basis of full decision trees [№4 за 2011 год]
Author: Генрихов И.Е.

Paper continues the series of works devoted to development of classification algorithms on the basis of full decision trees. This construction decision trees allows counting all the attributes that match the criteria bifurcation. Investigate questions of reducing overfitting a full decision trees with bifurcation entropy criterion. The results of testing on real problems are adduced.

36. Intellectual systems and algorithms of objects management in simulators [№4 за 2011 год]
Authors: Yanyushkin V.V., Захаров В.Л.

In article the idea of construction and introduction in simulator structure of neural network module is resulted, allowing to operate objects on the basis of adequate decision-making system a network trained during functioning, initial formalization of a problem on an example of a tactical simulator also is resulted and the basic problems in this area are designated.

37. The acceleration of spatial trees update by shells method [№4 за 2011 год]
Authors: Коробицын В.В., Сибара С.А.
Visitors: 7257
The method of objects' shells was applied for acceleration of spatial structures update based on the KD-tree. The method was used for dynamic scene visualization by raytracing technique. The results show the significantly reduced time on scene updates compared with method based on fully reconstruction.

38. The distributed calculations at the limited number of copies of the program resource [№4 за 2011 год]
Authors: Nikolay S. Kovalenko, Pavel А. Pavlov
Visitors: 8962
Problems of a finding of time of performance of the distributed competing processes are solved at the limited number of copies of a program resource in the conditions of the unlimited and limited parallelism.

39. Method for parameter estimation of nonlinear kinetic models of multistage chemical reactions [№4 за 2011 год]
Author: Писаренко Е.В.
Visitors: 8573
The basic stages of carrying out of kinetic studies, construction of high-precision kinetic models, and identification of kinetic constants of models, planning of starting and precision experiments are considered. A set of algorithms and programs for identification of kinetic constants of complex chemical reactions, planning of precision experiments and construction of optimal plans of experiments according to the criterion of a D-optimality has been developed.

40. Automatic reconstruction of three-dimensional objects from technical drawing [№4 за 2011 год]
Author: Zakharov A.A.
Visitors: 10607
Questions of automatic reconstruction of three-dimensional objects from technical drawing are considered. The algorithm of reconstruction of three-dimensional models on the basis of boundary representation is developed. The algorithm uses masks for recognition of typical structural elements of model. Practical results of work of algorithm are shown.
