23. Representation of graphs and undirected hypergraphs with constraints in a relational database [№4 за 2011 год]
Authors: (mokrozubv@yandex.ru) - , Ph.D; (nemtinov@mail.gaps.tstu.ru) - , Ph.D; (teotrall@mail.ru) - ;
Abstract: Describes a method of formal mathematical descriptions of graphs and hypergraphs with constraints in the form suitable for submission to the relational database, wherein the description in the graph is being restricted, represented in terms of set theory. Described the structure of a relational database, which allows to describe graphs and undirected hypergraphs with restrictions. Implementation of the restrictions provided referential and domain integrity of the database.
Keywords: adding and deletion, referential and domain integrity, relational database, contingencies, hypergraph, graph

26. Programming problems on graphs of bounded treewidth [№4 за 2011 год]
Authors: Bykova V.V. (bykvalen@mail.ru) - Siberian Federal University (Professor), Ph.D;
Abstract: We present the modern approach to development of efficient algorithms for solving optimization problems on graphs of bounded treewidth. This approach is based on dynamic programming using a tree decomposition of the graph. According to this approach we propose an exact algorithm for solving the VERTEX COVER problem. We apply the transformation of the tree decomposition which reduces the size of dynamic programming tables. In describing the algorithm, we use the language of relational algebra. Algorithm execution time depends linearly on the number of vertices and depends exponentially on the treewidth the original graph.
Keywords: relational algebra, dynamic programming, dynamic programming, tree decomposition, graph algorithms

28. Library for transcription factor binding sites search [№4 за 2011 год]
Authors: (evgeny.cheryomushkin@gmail.com) - ; Cheremushkin E.S. (evgeny.cheryomushkin@gmail.com) - A.P. Ershov Institute of Informatics Systems (IIS), Siberian Branch of the Russian Federationn Academy of Sciences, Novel Computing Systems in Biology (Research Associate), Ph.D; (evgeny.cheryomushkin@gmail.com) - ; (evgeny.cheryomushkin@gmail.com) - , Ph.D;
Abstract: 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.

Authors: Zotin A.G. (zotinkrs@gmail.com) - Academician M.F. Reshetnev Siberian State Aerospace University (Associate Professor), Ph.D; (umka.82@mail.ru) - ;
Abstract: 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.
