Item Information-Measuring Test System of Diesel Locomotive Hydraulic Transmissions(Дніпропетровський національний університет залізничного транспорту імені академіка В. Лазаряна, Дніпропетровськ, 2015) Zhukovytskyy, Igor V.; Kliushnyk, Ihor A.; Ochkasov, Oleksandr B.; Korenyuk, Roman O.ENG: The article describes the process of developing the information-measuring test system of diesel locomotives hydraulic transmission, which gives the possibility to obtain baseline data to conduct further studies for the determination of the technical condition of diesel locomotives hydraulic transmission. The improvement of factorytechnology of post-repair tests of hydraulic transmissions by automating the existing hydraulic transmission test stands according to the specifications of the diesel locomotive repair enterprises was analyzed. It is achieved based on a detailed review of existing foreign information-measuring test systems for hydraulic transmission of diesel locomotives, BelAZ earthmover, aircraft tug, slag car, truck, BelAZ wheel dozer, some brands of tractors, etc. The problem for creation the information-measuring test systems for diesel locomotive hydraulic transmission is being solved, starting in the first place from the possibility of automation of the existing test stand of diesel locomotives hydraulic transmission at Dnipropetrovsk Diesel Locomotive Repair Plant «Promteplovoz». Methodology. In the work the researchers proposed the method to create a microprocessor automated system of diesel locomotives hydraulic transmission stand testing in the locomotive plant conditions. It acts by justifying the selection of the necessary sensors, as well as the application of the necessary hardware and software for information-measuring systems. Findings. Based on the conducted analysis there was grounded the necessity of improvement the plant hydraulic transmission stand testing by creating a microprocessor testing system, supported by the experience of developing such systems abroad. Further research should be aimed to improve the accuracy and frequency of data collection by adopting the more modern and reliable sensors in tandem with the use of filtering software for electromagnetic and other interference. Originality. The authors developed the information-measuring system that improves the hydraulic transmission test process by automating and increasing the accuracy of measurements of control parameters. The measurement results are initial data for carrying out further studies to determine the technical condition of the hydraulic transmission UGP750-1200 during the plant post-repair tests. Practical value. The paper proposed the alternate design of microprocessor hydraulic transmission test system for diesel locomotives, which has no analogues in Ukraine. Automated data collection during the tests will allow capturing the fast processes to determine the technical condition of hydraulic transmission.Item Unified Digital Infrastructure of the Modern Scientific Library on the Basis of Web Technologies(Дніпровський національний університет залізничного транспорту імені академіка В. Лазаряна, Дніпро, 2019) Kliushnyk, Ihor A.; Kolesnykova, Tetiana O.; Shapoval, Olexander S.ENG: Purpose. Digitization, expansion of the scientific library infomedia and its integration into the global digital space require the creation of a full-fledged, multifunctional Web-oriented ecosystem. The work is aimed at researching rational ways and implementation of separate tools within the framework of an interactive library information system on the basis of Web-technologies, which includes a single API gateway (library site) and combines separate library management systems (LMS). Methodology. The research was conducted on the basis of the Scientific and Technical Library of the Dnipro National University of Railway Transport named after Academician V. Lazaryan (DNURT). We analysed the structure and condition of the existing out-of-dated library information system, based on the technologies of breaking up separate subsystems into separate services. We considered the possibilities and peculiarities of the transition to a single interactive system with the help of a central Web-application, which combines scattered services. This system is integrated into the system of «IRBIS-64» LMS (although any LMS can be used). Attention is focused on the reliability and protection of user data from unauthorized access. Findings. The ways, means and peculiarities of the transition to a full-fledged, multifunctional Web-oriented ecosystem of the DNURT library are explored. The system has its own API-based interface, which allows it to be easily scalable, thanks to the use of the current framework on the basis of Laravel – OctoberCMS. The system has an administrator and user panel. A subsystem – the DB «Publication Profile of University Science» –has been developed to provide the necessary functionality for plugins and applications: 1) for synchronization withScopus, Web of Science, Google Scholar – in Pyhton language; 2) for automated reporting – in C# language for Windows. Originality. The researchers analysed the possibilities and suggested optimal and effective solutions for creating an interactive information system of the library based on Web-technologies, which includes a single API gateway (library site) and combines separate library automation systems. It is proved that the application of the increased level of abstraction using specialized PHP-frameworks and ORM instead of pure SQL allows the developer to focus on the development of a rather complex and at the same time a simple system from the point of view of development, which is sufficiently effective in the absence of time and material resources in the scientific libraries of Ukraine. The performed researches allow to assert about the partial implementation of the «Library 2.0» paradigm requirements in the library of DNURT. Practical value. The offered interactive information system of the scientific library allows to practically abandon the cumbersome and morally outdated IRBIS 64 system in the issues of service for readers (there is an opportunity even to execute orders of printed literature in a personal account, like in user accounts of modern courier services). The developed software that synchronizes with IRBIS in the C# language allows to upload data from the IRBIS LMS to any modern open-source LMS in the future. Realization of possibilities of the subsystem «Publication Profile of University Science» will allow receiving a statistically reliable picture of the publication activity and influence of scientists, departments, university as a whole.
