Embedded System Simulation Using Renode †

Istvan Szalay Ferenc Péter Speiser Denes Fodor

Publication Name: Engineering Proceedings

Publication Date: 2024-01-01

Volume: 79

Issue: 1

Page Range: Unknown

Description:

In the automotive industry, the reduction of development costs is of key importance. The development of electrical hardware is an expensive, time-consuming process with a lot of development stages (e.g., prototyping, electrical testing, mechanical testing, lifecycle testing). There is a growing need to increase the cost-effectiveness of the development and testing phases of embedded software using virtualization. Using this method, less prototype manufacturing is necessary since the simulations allow for faster and more effective discovery of a large portion of possible faults without building a hardware prototype. Renode is an open source embedded system simulation framework that facilitates software-based testing. The main goal of this paper is to explore the usability of the framework for automotive applications.

Ádám Titrik

Publication Name: Engineering Proceedings

Publication Date: 2024-01-01

Volume: 79

Issue: 1

Page Range: Unknown

Description:

Hydroflight is a watersport where the user utilizes a waterjet-propelled backpack to fly over water. These backpacks are usually powered by purpose-built equipment but can also be propelled by personal watercraft. To have full control over movement during hydroflight, the user needs to adjust the throttle of the watercraft, which is commonly performed by converting the system to remote-controlled operation. However, care should be taken during conversion to ensure safe operation and avoid harm to the user. This paper presents a failure analysis of sudden safety mode activation on a personal watercraft converted to remote control for hydroflight applications, as well as actions taken to avoid full shutdown in the case of communication loss, without compromising user safety.

Description:

Purpose: Hijacked journals are fraudulent websites that mimic legitimate journals and, by charging authors, publish manuscripts. The current editorial endeavors to provide a close view of current literature. This editorial piece analyzes 10 years of research on hijacked journals and endeavors to shed light on future trends. Methods: Current research uses a bibliometric approach to analyze data and discuss results. The OpenAlex has been used for data collection. Some of the data analysis was conducted using OpenAlex. The other study was done using Bibliometrix, and the date is limited to publication between 2014 and 2024. Results: The findings provide a close view of the published literature in terms of access type, growth, topics, most frequent words, country contribution, top publishers, and alignment of literature with sustainable development goals. Conclusion: The gap in current literature is the limitation in easily usable methods to be accessible by all researchers for hijacked journal detection and data analysis. The use of artificial intelligence can be promising.

Tax knowledge in connection with tax compliance in Hungary

Katalin Borbély Rita Anna Ambrus

Publication Name: Journal of Infrastructure Policy and Development

Publication Date: 2024-01-01

Volume: 8

Issue: 11

Page Range: Unknown

Description:

During the examination of tax education, a significant part of the professional literature defines taxpayers as a homogeneous group, however, among others, the level of educational attainment and the digital skills of taxpayers are also important. This research investigates the role of knowledge in connection with tax compliance. The article is based on the statements from the professional literature and analysis of secondary data from national and international authorities and institutions. It also includes some comparisons of the components of the COM-B model on the data of nine European countries and sets up a model of tax behaviour based on Hungarian conditions. According to the classification based on the comparison, the performance of Hungary is at the lowest level among nine examined countries. Considering the complexity of the tax system, the knowledge of taxpayers is incomplete in Hungary. A developed version of the COM-B model points out that there is a close connection between capability and opportunity as well and these components can reinforce each other. With the adequate motivation and literacy as well as the knowledge of procedures can facilitate tax compliance. It can be concluded that successful tax education recognises and targets various groups of taxpayers. The Hungarian tax authorities treat taxpayers as a homogeneous group, however, there are slight developments by using several communication channels. In the current situation, the most important is to find the forms and levels of tax education to make the taxpayer able to comply.

Control of transfer function distortion during RPM-sweep testing of e-drive systems

Balázs Vehovszky Zoltán Gazdagh D. Acs B. Fukker

Publication Name: Proceedings of ISMA 2024 International Conference on Noise and Vibration Engineering and Usd 2024 International Conference on Uncertainty in Structural Dynamics

Publication Date: 2024-01-01

Volume: Unknown

Issue: Unknown

Page Range: 3779-3787

Description:

This study is focusing on the distortion phenomenon of the vibrational resonance peak when testing an e-drive assembly via RPM-sweep excitation. As the ramp rate increases, the measured response function deviates more and more from the stationary response. This distortion leads to a reduced peak amplitude, a shift in resonant frequency, changes in response shape and consequently, results in an increased half-power bandwidth, eventuating an increased apparent modal damping. These changes in the response are dependent on the sweeping direction and other physical parameters as well, like oil pressure and -temperature. The phenomenon was investigated earlier for linear systems, but not for operational testing of rotary machines, where the characteristics of the spectrum distortion are governed by different principles and are influenced by many other physical factors. A novel way for handling amplitude distortion of e-drives during transient testing is elaborated, which can be used to optimize RPM-sweep rate and other measurement parameters.

Induction Motor Energy Efficiency Investigation †

Istvan Szenasy Dániel Csikor

Publication Name: Engineering Proceedings

Publication Date: 2024-01-01

Volume: 79

Issue: 1

Page Range: Unknown

Description:

The energy efficiency of the induction motor (IM) is extremely important in the drives of electric vehicles. The first part of the article examines the possibilities of modifying the torque and efficiency curves in order to realize high-torque work points more efficiently by modifying the motor’s impedances. Later, it analyzes the flux-dependent changes in the highly load-dependent efficiency based on the literature. The FEM-type investigations of the experimental IM development carried out at the Vehicle Industry Research Center Institute of the Széchenyi István University offer new control options for increasing the efficiency of work points with lower torque and speed as well as for modifying the examined torque curve sections.

Description:

The rise of digital culture has fundamentally changed the way people learn in higher education. Online platforms, digital learning materials and various e-Iearning tools have become commonplace, significantly changing traditional learning methods. Access to information for students has never been easier: online courses, interactive videos and webinars allow flexible and personalised learning. At the same time, learners are moving from being passive recipients to active participants, as the use of interactive content and collaborative learning tools becomes more widespread. Digital methods offer new ways of acquiring and processing knowledge. Tools such as virtual reality (VR), artificial intelligence (AI)-based tutors and gamification-enhanced learning systems increase motivation and allow for a more personalised approach to learning materials. Higher education institutions are also increasingly open to innovation, with the introduction of online learning platforms and hybrid teaching models gaining ground. Through this transformation, higher education is no longer limited to classroom learning but is becoming a global process in the digital space. Our article explores these issues using our concrete tacit knowledge and experiences from higher education courses.

Éva Bednárik Rajermani Thinakaran Ferenc Erdos László Koloszár Alexandra Takáts

Publication Name: Edelweiss Applied Science and Technology

Publication Date: 2024-01-01

Volume: 8

Issue: 5

Page Range: 1400-1412

Description:

Industry 4.0 focuses on the digitalization of production processes and technological innovation. The concept of Industry 5.0 puts the focus on human-centricity, sustainability, and resilience at the heart of research and development and innovation (R&D&I) processes to allow industry to serve humanity with a long-term vision that considers planetary boundaries. Replacing the technology-driven approach with a fundamentally human-centric approach requires a deep understanding of the working environment and workers interacting with machines to optimize worker well-being, working conditions, and job outcomes. Analyzing computer work User eXperience (UX) in industrial environments is vital. However, user perceptions are usually hidden and a challenge to detect. Therefore, measuring and monitoring perceptions, emotional reactions, subjective elements, preferences, and attitudes in the relationships between usability, work performance, and workload is crucial. This study provides conclusions of a literature review on user experience studies focusing on UX testing methods and the disciplines linked to industrial diversification. Based on literature analysis, it identifies UX testing methods and create own grouping to analyze them. It also examines the disciplinary context of user experience testing.
