The article presents the results of comparative expert research to establish the importance of the applied national criteria for the quality of the educational program (CQEP) of higher education institutions (HEIs). For these studies, a group expert assessment of the importance of the CQEP for the educational program (EP) in the field of computer-integrated technologies was applied. The teaching staff of two universities is involved in conducting such an evaluation: The State University of Telecommunications (Ukraine) and the Gheorghe Asachi Technical University of Iaşi (Romania). To conduct this research, the existing CQEP and their sub-criteria and a special algorithm of group expert evaluation were used. It has been established that the most important CQEP and their sub-criteria include, first of all, CQEP regarding human resources, the educational environment, material resources, and the structure and content of the EP. The greatest spread of experts’ opinions (from the weightiest to the least weighty) can be stated for the sub-criteria of CQEP regarding access to EP and recognition of training results and transparency and publicity. With this in mind, this CQEP sub-criteria requires close attention when revising them for a better balance of the CQEP subcriteria system. Harmonization of the list of fields of knowledge and specialties for which higher education students are trained with the International Standard Classification of Education, as well as the national terminological and conceptual apparatus with the international one, should be considered extremely appropriate in Ukraine. The issue of prioritizing the preparation of higher educational institutions for the accreditation of the EP, meeting the most essential requirements of the sub-criteria of the CQEP, and taking into account their significant number, remains relevant. This also determines the relevance and necessity of conducting special expert studies on the comparison of the importance of CQEP for different fields of knowledge.
Comparative analysis of technical characteristics of charging stations of electric vehicles

The article analyzes and compares charging stations for electric vehicles and their components. The analysis of charging modes of electric vehicles showed that four internationally standardized modes are used, three of which use alternating current with single-phase and three-phase switching and only one – direct current. When charging on direct current, the fastest charging is provided. There are four standardized cases of connecting charging stations to electric vehicles. Three cases of cable connection can be used on alternating current, only the third case – on direct current, and the fourth case – when wirelessly charging an electric car. Analysis of the principles of use of charging stations showed that they classify portable, wall, and stationary stations. National standards introduce road signs for electric vehicles, and a European standard establishes harmonized identifiers for the power supply of electric vehicles. There are some standardized protocols for the interaction of the charging station and the control server, which are designed to optimize energy resources and energy production systems. A comparison of existing types of connectors for charging electric vehicles has shown that the standardized interface between the charging station and the electric vehicle remains one of the most acute problems. Recommendations on approaches to metrological support of charging stations are formulated. The issue of international and regional standardization of electricity meters of direct current for use in charging stations remains relevant. International standards are transformed into relevant European standards without changes. However, in some cases, it is necessary to develop a special European standard, in particular for meters of active electrical energy of the direct current.
Expert assessment of the competencies and results of bachelor's study according to the standard of higher education in information and measurement technologies
(Видавництво Львівської політехніки, 2023-03-01) Gordiyenko, Tetyana; Pototskyi, Ihor; Velychko, Oleh; Kuzmenko, Iurii; Salceanu, Alexandru; State Enterprise “Ukrmetrteststandard”; Gheorghe Asachi Technical University of Iaşi
The article establishes the relevance of researching the importance of applied competencies and learning results in the standard of higher education for obtaining the bachelor's degree in the specialty “Information and measurement technologies”. To achieve the goal, the description and requirements of competencies and learning results were analyzed, and an algorithm for group expert assessment of their importance was proposed and substantiated. Based on the assessment, the priority of professional competencies and learning results was established. The most important competencies and learning results that can significantly influence the quality of education in the specialty are determined. Competences and learning results with the least impact on the quality of education in the specialty have been identified, which may indicate their formal nature. To better balance the system of competencies and learning results, it is necessary to pay special attention to those that have the least influence during the next revision of the standard of higher education for the training of bachelors in the specialty “Information and measurement technologies”. The changes to the description of competencies and learning results proposed by the experts take into account the current trends in the development of the industry, provisions of current legislation, regulatory documents, and established terminology in the field of metrology and information and measurement technologies.
