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.

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

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.
