New forms of educational activity with the use of ICT tools (network interaction, multimedia lecture, online lecture, slide lecture, distance learning, electronic seminars, webinars, case technology, forum, e-mail consultation, computer testing, telecommunication project, group projects on wiki technology, joint blogging, etc.). In the article we opened didactic possibilities of application of innovative organizational forms in educational process. The peculiarity of the application of electronic lecture and its types (online-lecture, slide-lecture, video-lecture, combined lecture; laboratory works with the use of computer and appropriate software; independent work on informatics; network interaction and its resources (teleconference, chat, WWW) (World Wide Web), e-mail, FTP, blog), online communities and forms of educational activities (educational teleconference, off-line conference or virtual conference, chat, training workshop, virtual learning with the help of the pedagogical community, educational competition, joint creation of web pages, virtual survey of students, educational virtual project, virtual party, master class on a specific topic, design seminar, project festival, etc.), distance, blended learning and their software.</p> Andrii Shuliak Copyright (c) 2020 Andrii Shuliak Sat, 17 Oct 2020 00:00:00 +0200 GENERALIZATION OF THE EXPERIENCE OF USING DISTANCE LEARNING TECHNOLOGIES IN THE CONDITIONS OF REMOTE LEARNING <p>The article discusses the problems of organizing remote learning that have arisen due to the COVID-19 pandemic, provides the advantages and disadvantages of using various software tools and Learning Management Systems.</p> Bakunova O.

Data analysis, risk assessment technologies and decision support systems enable companies to adapt to modern challenges.<br>In the process of globalization, a consumer has the priority due to which quality of service and timely delivery of the required products determine the competition among the companies. All participants of the supply process, including logistics service providers, have traditionally focused on optimizing process management and minimizing supply chain costs [1]. The determining factor of supply efficiency from the perspective of procurement and logistics is the uninterrupted supply of raw materials and semi-finished goods that depends on the selection of a reliable supplier, as well as the continuous improvement of the quality of materials and the reliability of the customer-supplier relationship. The purpose of this article is to analyze use of blockchain technology to improve reliability of supply chains, whereas the rationale behind the management of business processes and the contractual obligation between the parties are verified cryptographically, using a smart contract.</p> Giorgi Doborjginidze, Lily Petriashvili, Mariam Inaishvili Copyright (c) 2020 The authors Tue, 08 Dec 2020 00:00:00 +0100 THE REFLECTION OF ELECTRONIC JOURNALS’ SUBJECT-MATTER IN A COLOR SYSTEM <p>The article examines an electronic journal as a modern type of a periodical from the standpoint of the distinguishing features of the color palette (color system). The topic of the color influence on the user in the electronic journals’ design has not been substantially studied to date. With the aim of attracting the target audience not only the content is important, but also the design.<br>The emphasis is laid on identifying the relationship between the color system applied for the journal’s design and its content (functional focus). The author sampled and analyzed a considerable amount of factual material, representing the examples of the electronic pages’ design of the journals and magazines of various types. In accordance with the division into thematic groups, characteristic color combinations and the patterns of their use on the page were identified. The thematic component is far from being crucial in choosing the electronic journal’s color scheme. The reason for this is the presence of a large number of additional factors affecting its formation. Moreover, there are general trends in graphic design that set conventional limitations for the color palette, especially the trend towards minimalism.</p> Hussain Abdulalee Falh Al Mnshdawy Ma Copyright (c) 2020 The author Tue, 15 Dec 2020 00:00:00 +0100 Achieve Efficient Distributed Scheduling with Cloud Message Queuing for Multitasking and High-Performance Computing <p>Due to the growth of data and the number of computational tasks, it is necessary to ensure the required level of system performance. Performance can be achieved by scaling the system horizontally / vertically, but even increasing the amount of computing resources does not solve all the problems. For example, a complex computational problem should be decomposed into smaller subtasks, the computation time of which is much shorter. However, the number of such tasks may be constantly increasing, due to which the processing on the services is delayed or even certain messages will not be processed. In many cases, message processing should be coordinated, for example, message A should be processed only after messages B and C. Given the problems of processing a large number of subtasks, we aim in this work - to design a mechanism for effective distributed scheduling through message queues. As services we will choose cloud services Amazon Webservices such as Amazon EC2, SQS and DynamoDB. Our FlexQueue solution can compete with state-of-the-art systems such as Sparrow and MATRIX. Distributed systems are quite complex and require complex algorithms and control units, so the solution of this problem requires detailed research.</p> Starovoitenko O. V.

Genetic algorithms are used in software development, in artificial intelligence systems, a wide range of optimization problems and in other fields of knowledge.<br>One of the important issues in the theory of genetic algorithms and their modified versions is the search for the best balance between performance and accuracy. The most difficult in this sense are problems where the fitness function in the search field has many local extremes and one global or several global extremes that coincide.<br>The effectiveness of the genetic algorithm depends on various factors, such as the successful creation of the primary population. Also in the theory of genetic algorithms, recombination methods play an important role to obtain a better population of offspring. The aim of this work is to study some types of mutations using a modified genetic algorithm to find the minimum function of one variable.<br>The article presents the results of research and analysis of the impact of some mutation procedures. Namely, the effect of mutation on the speed of achieving the solution of the problem of finding the global extremum of a function of one variable. For which a modified genetic algorithm is used, where the operators of the "generalized crossover" are stochastic matrices</p> Leonid Oliinyk, Stanislav Bazhan Copyright (c) 2020 The authors Wed, 23 Dec 2020 00:00:00 +0100
