31. The system of operative monitoring of supercomputer’s «URAN» temperature and power consumption [№4 за 2011 год]
Authors: (avs@imm.uran.ru) - , Ph.D; Goldshtein M.L (mlg@imm.uran.ru) - Institute of Mathematics and Mechanics Ural Branch of the Russian Federationn Academy of Sciences, Ph.D; (mach@imm.uran.ru) - ;
Abstract: The system of operative monitoring of supercomputer’s «URAN» temperature and power consumption is considered. The main advantage of the system is the compact monitoring data representation, which helps the administrator quickly diagnose the supercomputer using a couple of screens. The system based on the open source Zabbix software.

34. The method of innovation activity planning [№4 за 2011 год]
Authors: (geida@iias.spb.su) - , Ph.D; (ilys@iias.spb.su) - ; (ilys@iias.spb.su) - , Ph.D; (russell9@yandex.ru) - ;
Abstract: 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.

36. Research overfitting of recognizing procedures on the basis of full decision trees [№4 за 2011 год]
Author: (ingvar1485@rambler.ru) - ;
Abstract: 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.

38. The acceleration of spatial trees update by shells method [№4 за 2011 год]
Authors: (korobits@rambler.ru) - , Ph.D; (Sib.Sergey@gmail.com) - ;
Abstract: 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.
