The mechanism of fire risk management at the place for assemblage of people was developed. It is established that individual fire risk human deaths from fire exceeds the permissible value, therefore the additional fire prevention measures at improving the safe operation of the facility have been developed. It is shown that risks of people death on facilities of for assemblage of people largely depend...
Forecasting of weakly correlated time series of conversion rate by methods of exponential smoothing, neural network and decision tree on the example of conversion percent series for an electronic store is considered in the paper. The advantages and disadvantages of each method are considered.
The current state of the development of education in Ukraine in the field of information technology is analyzed. The ways of improving the efficiency of the educational training in the field of information technology are suggested.
The issue of the speed of information dissemination in the environment of social networks is considered. A conceptual model is proposed based on Monod equation, where biomass growth rate depends on the concentration of the substrate. A parallel between the main data of microbiological processes and processes in social networks is drawn. The major factors influencing information dissemination speed...
In this paper authors present the results of the effectiveness comparison between the variants of the Radix-2 Deci-mation in Time (DIT) Fast Fourier Transform (FFT) algorithm's implementations on graphics processing units (GPUs) which differ in the way the calculations are distributed among GPUs computational resources. The conducted experiments show that the partitioning of the FFT computational...

This article discusses the method of web-site content comparison with tourism documentation objects that is required to develop an information system of automated filling of tourism documentation. The feature...
Methods, algorithms and structures of neural networks were analyzed. Basic components of neural networks were defined and the principles of their development were chosen. It was shown that use of vertical-parallel method for implementation of work algorithms of neural networks basic components provides increased performance, reduce hardware costs and efficient VLSI implementation. Parallel-consequent...
In this paper a novel method for constructing a class of involutory parametric orthogonal transforms which can be calculated by the means of fast computational lattice structure of cosine-Walsh type transform is proposed. For this purpose all the necessary conditions that must be imposed on the values of transform parameters are formulated. Further on, the practical effectiveness of the proposed class...
This article is devoted to the developed method of development Smart-House-Systems Models, based on Petri-Markov Nets, and extended by functional components (sensors and actuators).
Today, the IT-infrastructures are widely used in various spheres of life. The advent of large Data Center(DC) has caused a problem of there resources management. One of this problem aspect is to allocate the DCs virtual machines(VMs) and load. Migration opportunity have added to the complexity of this problem. In this paper, the most used forecasting models are estimated with the aim of instrument...
This paper presents a scheme which aims to track patients in hospitals and to generate the suggestion information to the patients. In this scheme, hardware like location tracking devices such as GPS, WiFi positioning system, Bluetooth Low Energy (BLE), and RFID is not required. Instead, the proposed system entirely relies on the existing data in the Hospital Information System (HIS). The data analytics...
The complex analysis and systematization of mathematical and computer-oriented methods of processing historical information have been realized. The main directions of development of national science and summarized historical experience of information technology in the Ukrainian historiography of science is defined.
The method for extraction of face distributed features from pixel intensity columns and rows is considered. The features were applied to original and segmented faces. The greatest difference for faces was observed for segmented images. The proposed statistical features were tested for a face searching.
The basic features of some of the most versatile and popular open source frameworks for machine learning (TensorFlow, Deep Learning4j, and H2O) are considered and compared. Their comparative analysis was performed and conclusions were made as to the advantages and disadvantages of these platforms. The performance tests for the de facto standard MNIST data set were carried out on H2O framework for...
This document describes general information about web personalization and using third party services for cookie matching.
The problem of measuring the contrast of image elements (objects and background) for complex monochrome images is considered in this paper. A new method for measuring the contrast of image elements is proposed on the basis of analytical assessments of the contrast of the corresponding elements of the initial and inverted images. The new definitions for weighted and relative contrast of image elements...
The paper describes a simulation application for the process of evacuating people from a building in the event of a fire. This simulation was developed as an agent system using the DEVS formalism. The following sections show the design and implementation of such a system using the Adevs library. A series of simulation tests were then performed for different simulation scenarios.
