Learning lessons from projects is becoming increasingly critical to organizations and has peaked academics' and practitioners' interests. Although for many reasons in practice, the process of learning today to avoid making the same mistake tomorrow does not necessarily take place throughout the project's lifecycle. This paper is based on research aimed at examining the measurable impact of systematic...
The ecosystem model of surface water quality in the river basin was formalized on the basis of the theory of neural networks. The neural network is trained based on the observation data. Upon that the methods of environmental assessment and suitability of water for irrigation as well as for drinking needs can be used for the neural networking. The developed ecosystem model enables to improve significantly...
The paper substantiates the concept of building a three-phase model of the electric arc furnace in the instantaneous coordinates. The computer Simulink model of the electric mode of the electric arc furnace was developed. The results of testing the developed model are presented, the analysis of which shows that the required precision of the match between the experimental and simulated processes of...
The determining problem of several fracton mixture srtucture of materials grinding in the gas jet mill is considered. The problem is solved by comparing the standard deviation of the standart power spectral density of acoustics signals of individual fractions and of the mixture ones.
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...
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.
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.
Tourism documentation preparing is an important part of tourism activities because qualitative tourist services can not be provided without adequate information support in the present conditions. 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...
The article analyzes virtual communities as subjects of military and historical events in years 2014–2016 in Ukraine. The features and types of historical information that are created by virtual communities were analyzed.
The article presents the use of generative grammars in linguistic modeling. A description of sentence syntax modeling is used to automate the process of analysis and synthesis of natural language texts. The article reveals the features of synthesizing sentences of different languages with the use of generative grammars. The article examines influence of norms and rules of a language on the process...

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...
The article is devoted to designing of the control systems for weakly formalized objects using neural networks and fuzzy logic. An economical example is examined. The model of the predictive control system based on two neural fuzzy networks with the Sugeno interference is proposed. The first network is used for prediction of object's output, the second one for getting control signal. It's also proposed...
An improvement of the support of people with special needs' education will promote a social integration of such people. Developing mathematical and software methods and tools means to create a scientific base of information technologies, which task is to support an inclusive education. Leaned on the analysis of the nowadays support of inclusive education with information technologies, the model of...
This work presents an approximate model of spatially distributed Markov processes for the GIS-based real-time disaster Decision Support System. The proposed model uses possibility measures based on rough or fuzzy sets approach. The transition distribution of vague Markov jump-type process can be determined using the possibility values. The dynamics of the processes is represented as the motion of...
At given article implemented analysis of basic approaches to realization of automation of control by enterprise finances. According to results of analysis and consideration of new approaches to successful processing of management by funds flow, proposed development of new intellectual information system of finance management. The purpose of which is to present to user only necessary information —...
Program of efficient implementation of the discrete cosine transform of type-II using cyclic convolutions have been considered. The stages of automatic code generation of computing of DCT-II for arbitrary size N have been determined. The algorithm of DCT-II presents a better program performance for sizes of transform less than N=100, if compared with FFTW library.
Inductive learning has been employed successfully in various domains, however the inductive logic programming (ILP) systems focused on non-incremental learning tasks where independent sets of data are provided incoherently. In this paper, we propose a new genetic algorithm-based ILP system, called GAILP, for incremental learning. GAILP is a covering algorithm which extracts hypotheses/rules from a...
This paper contains analysis and extension of exploiters-based knowledge extraction methods, which allow generation of new knowledge, based on the basic ones. The main achievement of the paper is useful features of some universal exploiters proof, which allow extending set of basic classes and set of basic relations by finite set of new classes of objects and relations among them, which allow creating...
Problem of finding the optimal route for buyer at the store with additional conditions (given a shopping list) was considered. The model, based on the algorithm for finding the optimal route for buyer at the store, was described in the article. Developed model is based on the heuristic algorithm A∗ and on the nearest neighbor method. The main objective of the problem is reduced to solving the traveling...
