1. Automatic reconstruction of three-dimensional objects from technical drawing [№4 за 2011 год]
Author: Zakharov A.A.
Visitors: 10594
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.

2. 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.

3. Algorithm for identify trends for large noisy time series [№4 за 2011 год]

In this work efficient and accurate method for identify trends, denoising and smoothing for large nonstationary time series are provided. It is shown that the trends such large series can be determined the wavelet – packet transformation in combination with singular-spectrum analysis.

We developed library for searching transcription factor binding sites (specific fragments on DNA, where regulatory proteins binds. Those proteins are called transcription factors). Library consists of three search algorithms: direct search, permutation lookahead search and suffix arrays. Library is oriented on large scale information and allows performing search on genomic scale sequences with several thousand weight matrices.

5. 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.

6. Questions equivalent schemes of parallel programs [№4 за 2011 год]
Authors: Korablin Yu.P., Кучугуров И.В., Kosakyan M.L.

In this article discusses the equivalence of schemes of parallel programs. This allows you to analyze the program for various properties: detect deadlocks and locks in distributed program, loops, verify accessibility, to prove the equivalence (may, must, observational) of programs and branches.

7. High-performance calculations in simulation’s problems of percolation clusters’ behavior [№4 за 2011 год]
Author: S.Yu. Lapshina

Possibility of use of modern supercomputers is considered as the decision problems of multi-agent simulation growth modeling percolation clusters. The improved version of multiprocessing algorithm of repeated labeling percolation’s clusters is offered Hoshen-Kopelman. Possibility of revealing of dependences of the latent periods of distribution of epidemics from probability of an infection of units of population representatives, and also formations of threshold values at which local epidemics can evolve in large-scale pandemics is shown.

8. Determining of conserved hydrophobic cores in protein domains [№4 за 2011 год]
Authors: Пеков Ю.А., Алексеевский А.В., Спирин С.А.
Visitors: 11582
An algorithm and its realization as the program Conclus for analysis of data on protein structures are described. The program selects parts of a molecule that are evolutionary conserved hydrophobic clusters. Also the article contains a minimal information necessary for understanding biochemical and biophysical aspects of the algorithm. The program Conclus was tested on a number of families of protein domains and is equipped with a web interface publicly available via Internet.

9. Incremental replicating data for interaction information systems [№4 за 2011 год]
Author: Прилипко А.Г.

The method of incremental replicating data is described in this article. It is used in such interaction of informational system, which requires fractional periodical transferring data from one system to another. Several problems are described, where the decision is based on this method. Approach of tracing the history changing user data is proposed.

10. Intellectual systems and algorithms of objects management in simulators [№4 за 2011 год]
Authors: Yanyushkin V.V., Захаров В.Л.
Visitors: 12755
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.
