  • The paper considers the comparison of power consumption of Two’s Complement System and Residue Number System for digital signal processing applications. The comparison of these two implementations allows to conclude that, for these applications, the RNS uses less power than the TCS counterpart. The aim of the present paper is to highlight the reasons of this power consumption reduction.

    Keywords: residue number system, digital signal processing

  • Renumbering effectiveness for finite element mesh applied to finite element method for solving three-dimensional problems of solid mechanics

    This paper presents a comparative analysis of the effectiveness of the method Cuthill-McKee algorithm and fill-reducing ordering of a sparse matrix, based on multi-level nested dissection paradigm, developed at the Department of "Computer Science and Engineering," University of Minnesota. For short, we shall call the algorithm Cuthill-McKee CM, and the algorithm of the University of Minnesota — NodeND (Node nested dissection). This article uses a modification of the CM algorithm — RCM (reverse Cuthill-McKee), because in practice the reverse numbering index allows you to get a greater advantage than using a direct algorithm CM. The reason for using these algorithms are high speed computational algorithm, as it is necessary to solve the system proximal to the diagonal, the great acceleration of algorithms for solving FE problems using technology such as CUDA

  • Innovative business – the progress engine

    Only innovative activity is able to unite all aspects of science, equipment, economy, business and management. The current state of the innovative sphere of Russia speaks about serious contradictions in its functioning. Considerable scientific and technical capacity of the country was lost in the period of economic reforms. Now often it is impossible to predict precisely succession of events in economic life of the country generally and each organization separately. In modern conditions scientific and technical progress represents innovative development which is defined by the state as the most important priority of economic policy. Innovative potential of any managing subject needs to be estimated as difficult social and institutional system. To encourage managers and the production personnel competently developed motivational strategy is necessary to conduct work on search of innovations. Achievement of the put indicators of innovative development of the Rostov region and the country as a whole has to become result of an offered method of interaction of science, business and authorities.
