Description:
In this paper we present a complex Ecological Footprint (EF) analysis of one of the largest metropolitan regions in post-socialist East Central Europe, the Budapest Metropolitan Region. Our overall goal is to use both top-down and bottom-up approaches and measure the changes of footprint at a metropolitan scale between 2003 and 2013. Our specific objective is to explore how the spatial rearrangements of wealth, density and consumption influence the spatiotemporal changes of EF. The top-down (compound) calculations indicate growing footprint values both in Hungary and in the Budapest Metropolitan Region in the investigated period. However, household-level hybrid (component-based) calculations revealed decreasing footprint values for Hungary both in absolute and relative terms, and a growth for the metropolitan region. This finding suggests growing income disparities within the country. The indirect (consumption embedded) components of EF findings show that in the core city footprint values are higher due to higher disposable income. However, there is a gradual catching up in the suburban zone as younger and more affluent households arrive. On the other hand, direct per capita footprint values decreased in Budapest and grew in the suburbs between 2003 and 2013, mainly due to a higher heating footprint.

Analysis of Embankment Supported by Rigid Inclusions Using Plaxis 3D
Publication Name: Acta Technica Jaurinensis
Publication Date: 2021-11-24
Volume: 14
Issue: 4
Page Range: 455-476
Description:
A rigid inclusion-supported embankment is used to overcome the problems of soft soils. This system is considered complex due to the various interactions between its elements, namely the embankment body, load transfer platform, geogrid layers, piles, and soft soils. The load transfer mechanism is based on the phenomenon of soil arching, the tension in the geogrid layers, support of the soft soils, and friction between piles and soft soil. In this paper, the first part highlights the behaviour of a rigid inclusion-supported embankment validated by field measurements, and the contribution of rigid inclusions technology to the reduction of settlement and creep settlement. In addition, the effect of geogrid in improving the load efficiency and reducing the settlements is presented. In the second part, a comparison is made between many analytical design methods and a three-dimensional finite element analysis method. The results show the inconsistencies between the analytical methods in calculating the load efficiency and the tension in the geogrid.

Efficacy of Advanced Robotic and Virtual Therapy in the Treatment of Acute and Subacute Stroke Patients: a Feasibility Study
Publication Name: Acta Polytechnica Hungarica
Publication Date: 2025-01-01
Volume: 22
Issue: 10
Page Range: 83-102
Description:
The aim of this study is to compare the effectiveness of advanced robotic therapy, virtual therapy and conventional physiotherapy in the rehabilitation of patients with acute and subacute stroke. In addition, we aim to further demonstrate the importance of an early mobilisation exercise program in the management of acute stroke patients. Participants (first-time ischaemic stroke patients in acute or subacute stages) were randomly divided into three equal groups (n=10 persons/group): a robot-assisted early mobilisation + virtual reality therapy (ROB+VR) group, a robot-assisted early mobilisation + conventional physiotherapy (ROB+FIZ) group, and a conventional physiotherapy (CON) group. Each group performed a 3-week-long training program (1 hour/session, 5 days/week). The results were measured before and after the exercise. The primary outcome measure used was the modified Rankin Scale (mRS) which indicates the severity of disability in daily activities and measures the degree of independence of the individual. The secondary outcomes were measured by the EuroQoL 5 dimensions questionnaire 5 levels version (EQ-5D-5L), the Berg Balance Scale (BBS), the Barthel Index (BI), and the 6-minute walking test (6mWT). All the three groups showed improvements in most outcomes. The scores for BI, EQ-5D-5L, and mRS showed significant improvements in quality of life. Comparing the groups, the ROB+VR group showed the greatest improvement in the scores in almost all of the tests. From the test scores, the 6-minute walk test had the highest improvement at the end of the therapy (94.58% improvement). Our results show that early robotic mobilization, followed by a movement program, combined with a virtual reality therapy, significantly improve both the speed and quality of rehabilitation after a stroke.

Publication Name: Fusion Engineering and Design
Publication Date: 2010-01-01
Volume: 85
Issue: 3-4
Page Range: 370-373
Description:
A new camera system event detection intelligent camera (EDICAM) is being developed by the Hungarian Association and has been installed on the COMPASS tokamak in the Institute of Plasma Physics AS CR in Prague, during February 2009. The standalone system contains a data acquisition PC and a prototype sensor module of EDICAM. Appropriate optical system have been designed and adjusted for the local requirements, and a mechanical holder keeps the camera out of the magnetic field. The fast camera contains a monochrome CMOS sensor with advanced control features and spectral sensitivity in the visible range. A special web based control interface has been implemented using Java spring framework to provide the control features in a graphical user environment. Java native interface (JNI) is used to reach the driver functions and to collect the data stored by direct memory access (DMA). Using a built in real-time streaming server one can see the live video from the camera through any web browser in the intranet. The live video is distributed in a Motion Jpeg format using real-time streaming protocol (RTSP) and a Java applet have been written to show the movie on the client side. The control system contains basic image processing features and the 3D wireframe of the tokamak can be projected to the selected frames. A MatLab interface is also presented with advanced post processing and analysis features to make the raw data available for high level computing programs. In this contribution all the concepts of EDICAM control center and the functions of the distinct software modules are described. © 2009 Elsevier B.V. All rights reserved.

Development of comparative investigation method for timing chain wear analysis using oscillating tribometer
Publication Name: Acta Technica Jaurinensis
Publication Date: 2021-11-24
Volume: 14
Issue: 4
Page Range: 406-423
Description:
This paper presents the development of a test procedure to investigate timing chain components under abrasive stress on a tribometer. Engine developers use cost and time expensive engine dynamometer tests to investigate timing chain life expectancy under different conditions. Tribometer tests are fast and cost effective, but these use standardized specimen material and geometry that greatly differ from the original tribological system of the timing chain. Manufacturing specimens from the original chain material using the original technology is complicated; surface quality and hardness properties cannot be guaranteed. The aim of research was to develop a test method for rapid and cost-effective comparison of engine lubricants, timing chain materials or coatings, as well as to assess the wear resistance of the chain to contaminants. Various uncontaminated and carbon black blended lubricants were compared using standard-based ball-on-disc tribometer tests to tribometer tests using actual timing chain components (bush-on-pin test) of a Diesel engine. Lubricants were ranked in terms of coefficient of friction and wear. Results showed that bush-on-pin tests were comparably suitable for testing lubricants when evaluated against standard ball-on-disc tribometer tests.

Focus on onboarding process: Examining mentoring and training programs from the perspective of HR and employees
Publication Name: Journal of Infrastructure Policy and Development
Publication Date: 2024-01-01
Volume: 8
Issue: 12
Page Range: Unknown
Description:
In response to the rapid and dynamic changes in the economic environment, companies must improve their processes to maintain competitiveness. This includes enhancing their intellectual capital, with particular emphasis on effective onboarding processes, which play a crucial role in integrating new employees and retaining talent. This enhances the value of the organization’s intellectual capital and emphasizes onboarding—the training and integration of new employees—whose proper functioning impacts staff retention. Drawing on both Hungarian and predominantly foreign literature, we highlight onboarding processes and examine their implementation in Hungarian companies of various sizes. The research employed a mixed-method approach, combining semi-structured interviews and questionnaires. In-depth interviews were conducted with HR leaders from 13 Hungarian organizations to explore the existence of mentoring programs. Additionally, 161 employees across Hungary completed questionnaires, which examined their perspectives on onboarding processes and the relationship between mentoring programs and company size. We analyzed the data using chi-square tests to assess the strength of these relationships. While all large companies in our sample had formal mentoring programs, smaller companies displayed more variability, with some relying on informal or ad-hoc onboarding processes. Based on these results, we identified several key areas for improvement in onboarding processes. These include enhancing the structure of feedback interviews, ensuring more comprehensive communication channels, and strengthening mentoring programs across companies of all sizes. By addressing these gaps, companies can improve employee retention, engagement, and overall integration during the onboarding process, contributing to a more stable and motivated workforce.

Attitudes towards sustainable mobility technologies: Insights from electric vehicle adoption
Publication Name: Social Sciences and Humanities Open
Publication Date: 2026-06-01
Volume: 13
Issue: Unknown
Page Range: Unknown
Description:
The uptake of electric vehicles (EVs) plays a key role in the development of environmentally friendly transport solutions. This study explores factors influencing EV adoption in Hungary, with a particular focus on infrastructural and digital elements. Building on the theoretical foundations of technology acceptance models, the research shifts attention from individual psychological variables to objectively measurable external factors. The rationale for focusing on Hungary lies in its status as a post-communist, structurally constrained country with uneven access to digital services and public charging infrastructure. A nationally representative questionnaire survey of 2000 respondents was conducted to examine the intention to purchase EVs and its predictors. Regression results show that the availability of charging stations has a significant but weak effect on purchase intention (β = 0.145, p < 0.001, R2 = 2.1–2.5 %). Mobile internet coverage showed minimal impact (β = 0.087, p < 0.001, R2 = 0.8–1.4 %). Traffic congestion was positively associated with EV purchase intention (β = 0.168, p < 0.001, R2 = 2.9–3.3 %), indicating that residents of congested urban areas show greater interest in EVs. The findings suggest that while infrastructure matters, it alone is insufficient. An integrated strategy combining public incentives, infrastructure investment, and consumer education is needed to foster EV uptake. For policymakers and automotive stakeholders, the results highlight the importance of cost reduction, supportive regulation, and long-term sustainability benefits in promoting EV adoption in transition economies.
