The objective of this study is to examine the Radar Cross Section (RCS) of instruments designed for Autonomous Driving Systems (ADAS) testing, with the intention of comparing the results to those of actual human subjects. The RCS values of both dummy and platform objects were documented at varying distances and positions, with the objective of ascertaining the extent to which dummies can serve as substitutes for human values in vehicle radar sensing tests. The findings, substantiated by graphical representations and statistical analyses (e.g., Pearson and Spearman correlation), reveal a moderately strong positive correlation between the RCS and human values, which is statistically significant. The outcomes of the tests demonstrate that the developed instruments can substitute for real human radar cross-section values within the range of 5-15 m. However, as the distance increases, larger deviations are observed. These discrepancies underscore the necessity for a refinement of the dummy design in future ADAS tests, ensuring that distance-sensitive tests accurately reflect real human measurements.

In order to reduce the emissions caused by internal combustion engine vehicles, the industry is introducing more and more electric or hybrid vehicles to the market nowadays. The battery cells and modules of these vehicles require a lot of care, as improper or improperly maintained battery units can cause serious problems inside vehicles and can be extremely dangerous. The safest solution is to keep this unit of a vehicle under constant supervision so that it can be repaired immediately in case of an issue. Since all necessary data can be extracted from a vehicle’s communication network(s) through standard communication protocols, it is advisable to use them for continuous monitoring and diagnostics of units, while also considering cost-effectiveness and simplicity. The data received from here can also be used for measurement of electric powertrains and other parameters. However, since these data go through many conversions and computers (ECUs) before reaching us, their accuracy is questionable. In this study, we present our own custom battery diagnostic tool based on data extracted from a communication network. With the help of commercially available diagnostic tools, we also compare several measurements of the extent of the error limits of the data arriving at the communication network, how far they differ from the real values, and with the help of these, we analyze the accuracy of the device we have made. We present the commonly used Controller Area Network (CAN) communication protocol for passenger vehicles and briefly describe the construction of the high-voltage battery unit of the test vehicle.

A mai dinamikusan változó környezetben a vállalatok számára létfontosságú a technológiai fejlődéshez való alkalmazkodás, hogy versenyképességüket megőrizzék és növekedési lehetőségeiket kiaknázzák. A technológiai előrejelzési módszerek és a diszruptív technológiák egyre inkább középpontba kerülnek a vállalati stratégia kialakítása során, hozzájárulnak a hosszú távú sikerességhez és a piaci alkalmazkodóképesség javításához. A technológiai menedzsment módszerességének vizsgálata segíthet megérteni, hogyan befolyásolják ezek a tényezők a vállalatok pénzügyi teljesítményét, beleértve az árbevétel növekedését és a profitabilitást. A tanulmány a magyar-országi high-tech vállalatok esetében elemzi, hogy a technológiai előrejelzések és a diszruptív technológiák alkalmazása milyen hatással van a vállalati eredményességre. Az empirikus kutatás célja, hogy feltárja a techno-lógiai menedzsment módszereinek hatékonyságát és azok kapcsolatát a pénzügyi teljesítménnyel. A kutatás eredményei alapján kapcsolat mutatható ki a technológiai menedzsment módszeressége és a vállalati profitabilitás között: a fejlettebb technológiai menedzsmenttel rendelkező vállalatok kiszámíthatóbb, stabilabb pénzügyi teljesítményt érnek el. Emellett a diszruptív technológiák alkalmazása is növelheti a vállalatok árbevételét. JEL-kódok: O32, O33, L25

The research examines technological competencies from the perspectives of both human and technical components, emphasizing their significance in responding to corporate management challenges. Recent global changes have triggered significant technological transformations, presenting new challenges for corporate management. In this context, technological competence – encompassing both qualified human resources and technical innovations – plays a crucial role in the success of the responses provided by companies. The objective of the study is to demonstrate how technological competencies affect a company's economic performance and strategic adaptation capabilities. Data collected within the research framework included economic information provided by companies, such as revenue and staff numbers, as well as specific data related to technological forecasting methods. The analytical methods employed enabled the creation of a comprehensive understanding of the role technological competencies play in the economic context. The research underscores how the development of technological competencies can assist companies in successfully navigating through the challenges posed by technological changes. The findings indicate that the development of human resources and the integration of technological innovations are indispensable for strengthening corporate success and market position. Expert-type companies, which facilitate knowledge-based development and the introduction or marketing of new technologies, particularly benefit. In these companies, not just the technical equipment, but also human capabilities are decisive in successfully responding to technological challenges. This supports the importance of combining human resource development and technological innovations. The application of technological forecasting methods enables companies to better anticipate and manage market and technological trends, further strengthening their adaptive and innovative capacity. In summary, the research concludes that the harmony between technological competencies, knowledge, and corporate strategy enhances organizational competitiveness, highlighting the importance of knowledge-based development and the expansion of qualified human resources.

Purpose: In line with global changes, technology transition is apparent in many fields of operation. Companies facing with more and more challenges related to the new technologies, not only from technical but also management and competence point of view. The purpose of the paper is to show the survey results related to technology maturity of companies. The current paper approaches the challenge of technology competence from side of the new technologies. In the first part of the paper, the terminology of technology competence is overviewed, then interpretation of the relevant management challenges is presented. Methodology: The addressed problem is, how to approach identification of the technology competence level of a company, considering the current technology changes. Additionally, to the classic technical features, using relevant methods for forecasting the technology trends and systematic application of technology management might be relevant drivers for establishing a comprehensive technology attitude. This is the addressed research gap as hypothesis of the work. The key objectives of the consequent research of the authors are based on supposition that resources of a company are key influencing factors for the technology competence level which has a clear relation to the consequent company indicators. Findings: The current concept of the authors deals with both the soft, human aspect of the technology competence and the hard, technical aspect of it. During the correspondent research, a mirror-survey has been made: on one hand, aiming to understand the overall technology attitude of the selected companies, and on the other hand, attempting to evaluate the resource and asset figures of the involved companies for this purpose. Limitations: The paper shows the actual status of a longer-period research program. The limitations of the paper are given by the sample size involved so far. Nevertheless, the methodology presented here is expected to use in the next stage of the research when the sample size is extended. Practical Implications: Not only the actual values but also the trends of technical assets and human resource costs were analysed in order to make conclusions in relation to the technology competence features. The presented survey and analysis methodology themselves are also evaluated, to get conclusions for relevant future research from this perspective. Social Implications: The final outcomes of the paper include findings and conclusions to support the technology management approaches of the technology-intensive companies for sake of being able to better handle the relevant technology challenges. Originality: A method was given to approach the soft and hard aspects of the technology competence based on analysis of public available, technology-relevant business report data and assessment of personal interview answers. Finally, three types of organizations have been identified in view of the relevant technology competence pattern.
