Abstract: Analysis and modeling methods and tools for one of the modern directions in the field of aftersale manufactured product service-integrated logistic support stochastic systems are considered. Special attention is paid to the problems of analytical modeling and operating costs minimization in hydrid and hereditary systems. Keywords: software tools; stochastic systems; hereditary systems; stochastic shock impulse; analytical and statistical modeling; filtration; MATLAB AUTOMATIZATION OF PROGRAMS DEBUGGING FOR RECURRENT DATAFLOW PROCESSOR.
Abstract: The paper deals with the problems of low-level programs development and the ways of their decisions for the development environment of programs for recurrent dataflow processor. Realization of errors reduction and tools of automatic localization of errors leading to exceptions creation in hardware is described. Keywords: integrated development environment; debugging automatization; dataflow architecture; recurrence BUILT-IN DEBUGGING TOOLS OF RECURRENT DATAFLOW PROCESSOR .
Abstract: The paper deals with the issues of observability and controllability of internal states of the recurrent dataflow processor. The implementation of tools that enable the developers to maximally quickly detect, isolate, and correct the error issues is considered. The most effective decisions considering architectural novelty and specificity of the recurrent dataflow processor organization are suggested. Keywords: debugging; hardware; recurrence; dataflow architecture DATAFLOW ARCHITECTURE MODEL AND ITS USAGE WITH A WORD RECOGNIZER PROGRAMAS AN EXAMPLE.
Abstract: The imitational model of the dataflow recurrent architecture that is being imple- mented as application-specific integrated circuit at field-programmable gate array platform designed by Altera, is presented. This model lets the user to perform the debugging of the architecture's functional blocks before the hardware implemen- tation and serves as an instrument of software development and debugging. The architecture key aspects, specialized programming language, and their projection at the model are also presented. Keywords: imitational model; dataflow architecture; recurrence; programming AUTOMATION OF INFORMATION PROCESSING FOR DETECTION OF RAIL FORMS ANOMALIES.
Abstract: Based on the analysis of experimental data, the analytical models of the information processing from the meters of inertial-satellite system, fixing the anomalies of the form of the rails are suggested. The models are described by the nonstationary differential equations with unknown parameters. The obtained equations for estimation of the state vector of an integrated navigation system allowed to develop a method for identifying the parameters of the rails anomaly, free from the need to expand the dimension of the filter and the assumption of stationarity of the identifiable parameters and providing the improvement of accuracy of identification by the use of probabilistic criteria nonlinearly dependent on the a posteriori probability density of the state vector. Keywords: inertial-satellite system; rails form anomaly; a posteriori probability density of a state vector METHODOLOGICAL APPROACHES TO THE SELECTION OF SENSOR TECHNOLOGIES FOR THE SITUATION CENTERS BASED ON USERS ACTIVITIES CLASSIFICATION.
Abstract: The questions of application of modern touch technologies for the systems of the situation centers to increase the efficiency of their functioning on the basis of improvement of the interface of interaction of the person making decision with information and analytical system of decision-making support are considered. The criteria of touch technologies choice for a situation center on the basis of the carried-out classification of kinds of their users activity are suggested. Keywords: situation center; touch panel; interface of interaction; information and analytical system MATHEMATICAL TOOLS AND SOFTWARE FOR LIGHT DEVICES MODELING.
Abstract: The features of the light and light-distributing devices are described. The problems and possible solutions for their calculation and design are analyzed. Themathematical models used in the light and luminaire design with themirror reflectors are described. The principles of work with the created software for the automated modeling and design of the light devices are considered.

Abstract: The paper is devoted to science and technology fields interrelations analysis involving patent data of the Netherlands, Belgium, Chile, and other countries, as well as to the evaluation of level of significance of scientific papers cited in the patents from the corresponding fields, including the technological ones. Keywords: citing in patents; indicator of science and technology fields interrela- tions; information monitoring of science INTELLECTUAL MECHANISMS FOR SEMANTIC SEARCHING IN INTERNET.
Abstract: The methods of searching in Internet based on knowledge extraction from texts are considered. During the first stage, the significant key words are extracted from the question. They are used by the program-spider to select adequate texts from Internet. In the second stage, semantic-oriented linguistic processor is used. It analyzes the text of question and selected texts to form their knowledge structures. Semantic search consists in matching these structures and forming the answer for users. Various kinds of semantic search are considered. Keywords: semantic-oriented linguistic processor; knowledge extraction from texts; semantic search; knowledge base METHOD OF INFORMATION CLASSIFICATION BASED ON HIERARCHICAL TAGS AND ITS IMPLEMENTATION ON THE EXAMPLE OF A FAMILY ARCHIVE.
Abstract: The contemporary methods of classifying information are examined and their benefits and limitations are analyzed. Classification of heterogeneous information based on hierarchical tags is suggested, and the set of the problems for which this kind of classification is possible and suitable is analyzed. The implementation of the suggested approach in the program \Family archive" is examined. Keywords: classification; hierarchical tags; family archive SIGNAL PROCESSING METHODS FOR LOCALIZATION OF NONRENEWABLE REGIONS.
Abstract: This paper is devoted to the problem of myogram and magnetoencephalogram signal synchronizing. The evoked potentials have been used to localize the brain activity areas. The method is based on magnetoencephalogram data averaging with respect to the reference points. Voluntary movements start points were indicated as reference points. The main difficulty of magnetoencephalogram averaging was related to uncertainty in identification of voluntary movements start points. This paper presents a new accurate procedure for the reference points detection based on the stochastic characteristics of myogram and magnetoencephalogram. Two-stage procedure was suggested for voluntary movement start points localization. First, these points are identified according to myogram and/or actogram signal records and then revised according to magnetoencephalogram signal records. The obtained results can be applied in many scientific fields to solve various localization problems. Keywords: hypothesis testing; sample window variance; sample quantile; magnetoencephalography; magnetoencephalogram; actogram; myogram THE ARCHITECTURE OF HYBRID RECOMMENDER SYSTEM GEFEST
