11. The joint description of spatial and attributive data on the basis of multivariate information objects [№3 за 2011 год]
Authors: O.I. Khristodulo (o-hristodulo@mail.ru ) - Ufa State Aviation Technical University (Professor), Ph.D;
Abstract: The method of the joint description of spatial and attributive data on the basis of the multivariate information objects has been proposed which can be used for integration of diverse databases in corporation information systems. It allows to describe each type of geographical object in the form of MIO, to reach a generality for the object’s layer description between different types, to simplify the existing database structure of data processing systems and to make model of data observable and understandable.
Keywords: operation of addition of dimensionality, geographical object, information processing systems, multidimensional information objects, attribute and spatial data

12. The influence of utility function form on multi-criteria choice results [№3 за 2011 год]
Authors: (svm@sm4265.spb.edu) - , Ph.D; (mrhe1190@gmail.com) - ;
Abstract: It is investigated the influence of utility function form on multi-criteria choice results. It is considered the concave and convex form of utility function. On example of two-criteria scalar optimization the estimation difference is demonstrated between linear and non linear utility functions. The difference is proportional to degree of the non linear utility function. To achieve the acceptable result of optimization, it is necessary more carefully design the utility functions of the aggregated attributes.
Keywords: scalar optimization, multiplicative function, additive function, generalized function, linear utility function, convex, concave, utility function

13. Organization of adaptive computing systems streaming data processing [№3 за 2011 год]
Authors: (pogrebnserg@mail.ru) - , Ph.D; S.V. Ignatev (pogrebnserg@mail.ru) - Yaroslavl Higher Military College of Air Defense (Professor), Ph.D; (pogrebnserg@mail.ru) - ; (an_ta_vi@mail.ru) - ; Dopira R.V. (rvdopira@yandex.ru) - NPO RusBITex (Professor, Head of Department), Ph.D;
Abstract: The principles of organization of parallel computing systems, oriented on processing streams of interrelated data and having the logical adaptation ability to the structure and parameters of the input dataflow. Adapting to the dataflow structure is achieved on account of certain architectural and structural solutions that provide a high degree of parallelization of an input stream.

14. Integrating CLIPS with rule-based expert system [№3 за 2011 год]
Author: (savva_dorovsky@front.ru) - ;
Abstract: Embedding CLIPS kernel within C++-written program arises a problem of interaction between program and kernel. Method of organizing program interface between C++ program and embedded CLIPS is suggested. CLIPS and C++ functions and data constructs, developed for information exchange between program and embedded CLIPS, are described.

18. SLIPH4M – a program for numerical solution Of the Sturm-Liouville problem [№3 за 2011 год]
Authors: (votrongthach@jinr.ru) - ; (puzynina@jinr.ru) - , Ph.D;
Abstract: A program written in the language of the computer algebra system MAPLE is presented to calculate the spectrum of eigenvalues and corresponding eigenfunctions of Sturm–Liouville differential equations. In the program the iteration schemes are realized on the base of a continuous analog of Newton’s method with accuracy O(h4), where h is the step size of the uniform grid.
