The paper describes a software product which enables calculation of the vacuum freeze-drying process and to select the parameters of the process. Using the developed program, the user can calculate the time of the process of changing temperature regimes. The program is based on a mathematical model describing the processes occurring in the local volume, the displacement of the interface.

22. Approach to automatic construction of hydrodynamic models [№4 за 2011 год]
Author: Доровский С.В.

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.

23. Automatic reconstruction of three-dimensional objects from technical drawing [№4 за 2011 год]
Author: Zakharov A.A.

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.

24. Application of multispectral segmentation for the green vegetation status analysis based on video [№4 за 2011 год]

In the article the question of applying a multispectral segmentation for the analysis of the plants images is discussed. We propose a method of performing a multispectral segmentation based on modified threshold segmentation, using several color models. The ways of performance improvement of the system, which uses the proposed methods and algorithms, are described. The results of the experiments are presented.

25. Algorithm for 2-d scalar fields isolines on regular grids [№4 за 2011 год]
Author: Kandalov P.I.

The technique and algorithm for creation of 2-D scalar fields isolines on the regular grid by the algorithm of Marching Squares is considered. The algorithm is implemented in program language Pascal. The technique of filling of areas by a color palette between adjacent lines of level is described too.

26. Analytic hierarchy process in system of estimation of innovational degree of educational projects [№4 за 2011 год]
Author: Киреев В.С.

Article is devoted the description of system of the indicators having key value at an estimation of innovational degree of educational projects. Indicators of innovational degree are divided on two basic categories, each of which is in details described. Data on the developed Web application realizing the given approach are resulted.

27. Optimization of placing of trajectory measurements means by genetic algorithms [№4 за 2011 год]

The approach to optimum placing of trajectory measurements means with application of genetic algorithms is described. The offered approach is illustrated by means of results of mathematical modeling.

28. The distributed calculations at the limited number of copies of the program resource [№4 за 2011 год]
Authors: Nikolay S. Kovalenko, Pavel А. Pavlov

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.

29. Vector systems of averaging on the graphs [№4 за 2011 год]
Author: Коганов А.В.

It considers the operators of function averaging which defined on vertexes of oriented graph with finite vertex number. The averaging occurred in every vertex by incident vertexes in the graph with weights determined on detected edges in graph. It researched necessary and decent condition for that operator has convertibility in form of power-mode row. If those conditions are not true then it builds the additional operators for getting convertibility vector operator, and that extension is minimal in any sing determine meaning.

30. Process semantics of distributed programming language [№4 за 2011 год]
Authors: Korablin Yu.P., Кучугуров И.В.
Visitors: 10825
In this article the semantics of distributed programming languages researched by comparing programs a set of computational sequence and analysis of the semantic values thet can be represented by systems of recursive equations. It can detect deadlocks and locks in distributed program, loops, verify accessibility, to prove the equivalence (may, must, observational) of programs and branches.
