This paper presents the current problematic of development a set of indicators user direction, informational direction and reputational direction to perform task of directions of the organization of life cycle of virtual community. The method of determination of possible variants of balancing indicators of virtual community is developed. These indicators based on the analysis of the subject area of...
In this paper, we explore the task of intellectual information system creation for content formation. We developed the general recommendations for design of the intellectual system. Our system has special modules for processing of information resources. We created the software for formation, control, and implementation of content and made experiments on “Online newspaper” and “Online magazine” systems...
This article is addicted to the analysis of the main components of informational environment in the universities. The authors provide the characteristics of the chief documents load at universities. It is proposed the informational and analytical systems to be used in order to manage the informational and documental environment at the University.
This article dials with the problems of information search in company knowledge management system by keywords and belonging to some category. The approach of weight coefficients correction based on user activity statistics is considered; also, associative analysis that allows to determine keywords bonds in measure of user request is used.
This article describes the methods and tools to verify the location of nodes in wireless sensor networks. Software product that allows to analyze the positioning based on the distance with different algorithms is proposed. As a result of simulation the next statistical output variables are defined: percentage of nodes, which have position determined; minimum, maximum and average error in assessing...
The article considers methods of processing uncertainties in solving dynamic planning problems. Various types of uncertainties are considered, such as stochastic uncertainties, uncertainties in the parameters and structure of models, the uncertainty of the amplitude type and the probabilistic type. Methods for processing data for reducing uncertainties are proposed.
A new approach to optimum processing of multi-dimensional data arrays for advanced information technologies and education informatics, using innovative mathematical principle based on the combinatorial configurations expounds in this paper. This approach relates to the optimum arrangement of structural elements in two-or multi-dimensional arrays with respect to minimizing of retrieval capacity, and...
Model matching is a fundamental operation for various model management aspects such as model retrieval, evolution, and merging. An accurate matching between the elements of the matched models results in a better model management. This paper presents a Hybridized Greedy-Genetic algorithm for matching UML class diagrams, considering their lexical, internal, and structural similarity. Additionally, using...
The technology, which is implemented using cross-platform tools, is proposed for modeling of gesture units of sign language, dynamic mapping between states of gesture units with a combination of gestures structures (words, sentences). The technology implemented simulated playback of gesture items and constructions using virtual model of spatial hand. With the cross-platform means technology achieves...

In this research study, the authors developed the algorithms for computing the minimum distances between non-convex polygons. The purpose of the study is to develop the algorithm that transforms non-convex polygons into multi-convex polygons and the algorithm that computes the minimum distances between polygons on the basis of Gromov-Hausdorff and Gromov-Fréchet metrics. The proposed algorithms have...
The problem of corporations bankruptcy risk forecasting is considered under uncertainty and unreliable information. For its solution the application of fuzzy neural networks (FNN) with inference of Mamdani and Tsukamoto is suggested. Fuzzy inference rules and forecasting algorithm are developed. The experimental investigations of FNN application for bankruptcy risk forecasting of Ukrainian enterprises...
Paper describes methods of diagnosis vibrating processes to determine the state of the system and its structures. Describes the technology of data selection and processing in the diagnosis vibration of parts.
The paper considers the technology of finding Internet sources of historical information, taking into account their potential as information fixators of historical events, surveillance and retrospective analysis of events. It touches upon the issue of reliability of the information distributed, its factual and documentary grounds in conditions of information confrontation. It provides the method of...
The problems of implementation and benefits of archival information retrieval system for processing information requests of citizens in the structural units of higher educational establishments are considered. It is proposed to automate the delivery of services in pursuance of biographical and factual queries by archival departments of universities through issuing archival information, excerpts and...
A new mathematical principle relating to the optimum placement of structural elements in spatially or temporally distributed information systems (e.g. 2D data arrays) with respect to redundancy and vector processing speed, using novel design based on combinatorial configurations expounds. The research covers various aspects of modern computer sciences and information technologies including a teacher...
There is an image filtration using an Ateb-Gabor method realized. Filtration in the frequency area requires implementation of such changes sequence: discrete two-dimensional image transformation from spatial area to the frequency area. Filtration makes it possible to realize more combinations of filtering and conduct more qualitative transformation. Proposed method allows to expend a Gabor filter...
The geoinformation technology of spatial analysis and visualization of greenhouse gas emissions has been proposed using Google Earth Engine cloud technology as a key component of interaction with spatial data. As input data we use the vector data on emissions at the level of point, line and areal emission sources, which are converted to the raster emission data. The geoinformation technology includes...
