AutoCAD program of Autodesk company, CAD Kompas 3D program of Askon company are widely used for computer design in CAD system. These programs use involves not only knowledge of computer graphics basis, but also knowledge of design stuff itself, requiring vocational training. Microsoft Office Visio practical design in CAD system is considered in this article; it is updated, thus it simplifies computer design and improves its quality.

33. The language for description of problem domain model in the software packages [№1 за 2011 год]
Authors: Oparin G.A., Feoktistov A.G., Горский С.А.

Intellectual software is elaborated to support the mathematical modeling process for medical ecological economical systems. Main features, components and framework are discussed. The software considered is applied to automatize the formation process of the models discussed by using the formalization of expert experience.

35. Image retrieval using semantic features [№1 за 2011 год]
Author: Papulin S.Yu.
Visitors: 19005
This article describes image retrieval using semantic features which is based on conversion from visual features to convenient form for human perception. Particularly, on these pages considered general conception of image retrieval via textual description of image features and textual retrieval via semantic features of image.

36. Program-methodical complex for optimization of data collection systems [№1 за 2011 год]
Authors: Пацей Н.Е., Придухо В.Т.
Visitors: 14277
The article describes the tools and techniques for automation of designing data collection systems. These systems are the basis for the creation of automated control systems and electricity metering. Described program-methodical complex and methodology integrates all stages of the design: structural synthesis, synthesis and parametric analysis of the system. The article describes methods for finding solutions are used at each stage.

37. Factor analysis in problems of simulation of multidimensional systems [№1 за 2011 год]
Authors: Пащенко Ф.Ф., Дургарян И.С., Голяк И.В.
Visitors: 16221
The problems of identification of multidimensional stochastic systems and predict the output signals. To reduce the dimension of the problem is proposed to use the techniques of factor analysis and Kalman filter. Algorithms to identify and obtain equations for the parameters of the objects.

38. The concept of face detection algorithm and face analysis on digital image [№1 за 2011 год]
Authors: Перепелицын А.В., Butenko D.V.
Visitors: 17301
This paper describes a new hybrid algorithm for face detection on digital images. The main feature of the algorithm is that it uses an image processing after face detection with classic AdaBoost algorithms. This hybrid algorithm may be using for any kind of face contours test.

39. Program implementation mathematical model of heart rate variability [№1 за 2011 год]
Author: Романова Г.В.
Visitors: 18042
The mathematical model of heart rate variability has been described. Difference equations are used a mathematical apparatus. Such approach as this is more adequate to impulse character of cardiac beats. There is the flowchart of program realizing this model.

40. Networking and multithreading architectural aspects of distributed DBMS [№1 за 2011 год]
Authors: Смирнов К.К., Чернышев Г.А.

The problems of network communication between nodes and interthread communication are crucial aspects to consider designing a distributed DBMS. In this paper we concentrate on a query engine capable of processing multiple requests from a large number of connected clients. We review several possible approaches to the problem and evaluate them using our query engine.
