42. An algorithm for solving optimal and hard control [№3 за 2011 год]
Authors: (alevtinak@inbox.ru) - , Ph.D;
Abstract: Article is devoted to a algorithm of numerical solution for optimal control and hard to degenerate linear differential systems. Such systems arise, for example, when creating a balance of dynamic models, in the modeling of measuring devices. The algorithm is implemented in C++, the article shows the block diagram of the program and the results of computer simulation.
Keywords: the degenerate linear differential systems, efficient and strict management, algorithm program

43. Objects detection algorithm for permanent monitoring [№3 за 2011 год]
Authors: (a.kurakin@inbox.ru) - , Ph.D;
Abstract: In conditions of permanent monitoring, the object detection is performed by Baysian (not Neuman-Pearson’s) approach to statistical hypotheses chase. Permanent character of the process makes it possible to increase precision by accounting a priory probability of the object presence. Recurrent relations for cyclical processing of sequential data are presented in the article.
Keywords: a priory probability, cyclic algorithm, statistical hypotheses choice, making decision systems, objects detection, the automated information system

44. Management of intellectual resources of projects in the field of nanotechnology [№3 за 2011 год]
Authors: Stoyanova O.V. (ovstoyanova@list.ru) - Smolensk Branch of the Moscow Power Engineering Institute, Ph.D; Dli M.I. (midli@mail.ru) - (Smolensk Branch of the Moscow Power Engineering Institute, Ph.D; (vasicina@mail.ru) - ;
Abstract: This article describes an approach to management of intellectual resources of projects in the field of nanotechnology. It covers the stages from the initial accumulation of data and obtaining of intellectual resources to creation the models needed to build the knowledge base of the project, which includes all the available intellectual resources. An example of the practical use of the developed approach for the project to obtain glass-matrix composite materials based on titanium carbide is resulted. Particular attention is paid to the phase of research characteristics of the intellectual resources, which are represented in the form of mathematical models, and allow to estimate the oxidative properties of the composites.
