New Ways of Career Orientation for the Automotive Scope: Future Engineer Program of University of Győr Zalaegerszeg Innovation Park
Publication Name: International Journal of Automotive Science and Technology
Publication Date: 2025-12-17
Volume: 9
Issue: 1st Future of Vehicles Conf.
Page Range: 82-89
Description:
Today’s rapid developments have resulted in a change in students’ attitudes and their attitude to learning. In order to provide effective education, it is necessary for educational institutions to understand these changes in attitudes and to adapt the organisation and methodology of education accordingly. In addition, institutions need to take on new roles in an era of globalisation and rapid technological change in order to contribute to social and economic development. In this respect, teaching methods based on practicality may come to the fore; the use of inductive approaches may be an excellent response to this new challenge. The university preparatory course of the University of Győr - Zalaegerszeg Innovation Park builds on the above. The Future Engineer - ZalaZONE is a 6-week series of special, unique elements; a set of methods aimed at introducing and familiarising secondary school students with research and project-based education and practical skills, while at the same time supporting the university’s engineer career orientation. Since 2023, the course has been organised on six occasions, engaging 100 participants. A further unique and special feature of the programme is the creation of a course covering automotive topics, targeting secondary school students in the Zalaegerszeg Innovation Park environment, especially in a strong connection of R&D activities, industrial services and academic partnership. Briefly, this article brings a new look to the existing literature in the following areas: (I) alig ning inductive, practice-centred approaches (IBL/PBL) with the evolving learning attitudes of Generation Z and Alpha; (II) documenting the design of a university preparatory course embe dded in a science-park ecosystem that integrates R&D infrastructure and academic partnership; and (III) demonstrating a transition from subject-based instruction toward integrated automotive themes that stimulate complex, experience-based learning.

Regulation of Autonomous Vehicles in Public International Law from the Aspect of International Transport
Publication Name: International Journal of Automotive Science and Technology
Publication Date: 2025-12-17
Volume: 9
Issue: 1st Future of Vehicles Conf.
Page Range: 60-66
Description:
The issue of autonomous vehicles is one of the most pressing issues of our time that raises important questions regarding the territory of public international law. The development and spread of autonomous vehicles require predictable international regulation, which is extremely necessary in the field of international transport, where several steps have been taken in this direction. The aim of the study is to reveal and evaluate the actual overview of the state of regulation of autonomous vehicles within the field of international transport, paying special attention to the work of United Nations Economic Commission for Europe (UNECE) and the World Forum for Harmonisation of Vehicle Regulations (World Forum). For this purpose, the study analyzes the steps taken so far, presenting the two ways of regulation within these organs: the amendments of the existing rules of international transport and the creation of new documents for autonomous vehicles. With analytical, descriptive and comparative research methods, the study examines the question of whether these regulatory efforts are sufficient and what further steps should be taken to address the issue of autonomous vehicles in a satisfactory manner. The study comes to the conclusion that both the amendments and the new documents created so far have disadvantages, due to which they should be only regarded as starting points and the work should be continued in the direction of a new, precise and binding international treaty or treaties on autonomous vehicles. Based on the results of the study, this solution could contribute to the safety, sustainability and future of autonomous vehicles and international transport.

Robust Control of a Quadcopter BLDC Motor: Comparative Analysis of PID and H∞ Controllers
Publication Name: International Journal of Automotive Science and Technology
Publication Date: 2025-12-17
Volume: 9
Issue: 1st Future of Vehicles Conf.
Page Range: 1-6
Description:
The aim of the present study was to investigate a control strategy designed for the BLDC (Brushless Direct Current) motor of a quadcopter-type drone, with particular emphasis on the precise and stable maintenance of altitude in a disturbed environment. Two different control methods were implemented and compared during the research: the classical PID (Proportional-Integral-Derivative) controller and the H∞ (H-infinity) control technique. The investigations were carried out along two approaches. On the one hand, a transfer function—reproduced from a previous study—was used as a possible reference, and tested in the MATLAB simulation environment. On the other hand, a custom-developed physical prototype with one degree of freedom was created, capable of vertical motion along a single axis, allowing for the examination of altitude control under real-world conditions. The purpose of the system was to maintain a predetermined hovering altitude even in the presence of external disturbances, such as artificially generated wind. During the design of the control algorithms, a state-space-based modeling approach was applied, and appropriate weighting functions were defined, with special attention given to robustness against disturbances, control accuracy, and energy-efficient operation. The simulation results showed that the H∞ controller reduced average power demand by 19.43% compared to PID control, while practical measurements demonstrated a 38% decrease in average power consumption. In addition, overshoot was reduced by 96% and oscillation amplitude by 86% under wind disturbance. The objective of the research was to examine the practical applicability of an advanced control method that can provide greater stability, reliability, and energy efficiency under varying environmental conditions compared to traditional solutions.

The Effect of Heat Treatment on the Mechanical Properties of Continuously Fibre-Reinforced Standardised Specimens
Publication Name: International Journal of Automotive Science and Technology
Publication Date: 2025-12-17
Volume: 9
Issue: 1st Future of Vehicles Conf.
Page Range: 22-27
Description:
This study investigates the influence of post-printing heat treatments on the mechanical characteristics of 3D-printed specimens strengthened with continuous Kevlar filaments. After their fabrication, the specimens underwent thermal annealing at temperatures of 100 °C and 150 °C for either 1 or 3 hours. To assess the effects of these treatments on mechanical performance, tensile tests and microscopic analyses were performed. The findings indicated that the most significant enhancement was observed in specimens annealed at 150 °C for 1 hour, which resulted in an approximately 20% increase in tensile strength compared to untreated samples. Heat treatments at 100 °C for 1 hour and 3 hours led to moderate improvements of 5–8%, whereas extended treatment at 150 °C for 3 hours resulted in a reduction of about 10% in tensile strength. Microscopy revealed that brief, high-temperature treatment enhanced interlayer bonding and decreased internal stress without harming the structure, while prolonged thermal exposure led to local delamination and compromised fibre–matrix adhesion. These results suggest that controlled post-printing heat treatment can enhance the mechanical properties of continuous fibre-reinforced composites, though excessive heat exposure can lead to degradation. Therefore, careful optimisation of temperature and duration is crucial. The outcomes offer valuable insights for improving the structural performance of additively manufactured continuous fibre-reinforced components.

Incorporating climate and land use projections with spatial optimization of best management practices for soil erosion and sediment control in a semi-arid mountainous watershed
Publication Name: Science of the Total Environment
Publication Date: 2025-12-15
Volume: 1008
Issue: Unknown
Page Range: Unknown
Description:
Effective watershed management requires anticipating environmental changes and implementing strategies to reduce soil erosion and sediment yield. However, the effectiveness of structural and biological best management practices (BMPs) under combined climate and land use/land cover (LULC) changes remains poorly understood in semi-arid mountainous regions, where implementation is limited by site-specific factors such as soil depth, slope, rainfall, and LULC. This study quantified hydrological and sediment dynamics in the Taleghan Watershed, Iran (823 km2), dominated by rangeland, for baseline (1990–2010) and future (2020–2040) periods. Future climate scenarios were derived from downscaled CanESM5 projections (SSP2-4.5), and 2038 LULC was simulated using a Cellular Automata Markov model. SWAT was coupled with the Non-dominated Sorting Genetic Algorithm II (NSGA II) to optimize the selection and spatial allocation of BMPs including seeding, pile seeding, contour farming and check dams within critical source areas (CSAs) to reduce sediment yield and implementation costs under feasibility constraints. Results showed a rise in maximum (21.5 °C to 22.2 °C) and minimum (7.2 °C to 7.3 °C) temperatures, a 4–11 % increase in mean annual precipitation, and rangeland improvement, with moderate rangeland increasing from 31 % to 42 %. Soil erosion increased by 32 % under climate scenarios but decreased by 7.5 % under land use change, whereas their combined effects led to 23.8 % higher erosion and 6.5 % greater sediment yield. Among biological measures, pile seeding was most widely applicable, though feasibility constraints limited sediment control with reductions of 3.8 to 4.8 % along the Pareto front. Integrating feasibility constraints with climate and land use projections provides conservative yet practical insights for sustainable watershed management in semi-arid mountainous regions.

Investor Bias in ESG Ratings: Implications for Sustainable Portfolios
Publication Name: Ecocycles
Publication Date: 2025-12-15
Volume: 11
Issue: 2
Page Range: 67-77
Description:
ESG ratings are crucial tools that align financial strategies with the purpose of sustainability. Their reliability is often undermined because biases distort their comparability and dependability. The present study offers a novel contribution to the multidimensional analysis of biases in ESG ratings. Focusing on methodological inconsistencies, like firm size disparities, media influence, and self-disclosure practices. The unique contribution is integrating a behavioural finance perspective, considering psychological biases related to confirmation, overconfidence and herding behaviour factors that affect investor interpretation of ESG scores. This study synthesizes literature from diverse sources to identify the combined effects of these biases on capital allocation, market dynamics, and sustainable investment outcomes. It is a call for standardized ESG rating methodologies, increased transparency, and heightened awareness in practice to overcome these biases effectively. The actionable insights provided will help policymakers, rating agencies, and investors to create a more equitable and trustworthy ESG evaluation frameworks.
