Architecture of a Socialist Industrial Giant

Gergely Hartmann

Publication Name: Epites Epiteszettudomany

Publication Date: 2026-03-01

Volume: 54

Issue: 1-2

Page Range: 199-236

Description:

My study examines the industrial buildings realized between 1963 and 1990, the political transition in Hungary, developed through the collaboration between the Rába Hungarian Wagon and Machine Factory (Rába MVG) and the Győr Design Company (Győriterv), primarily from an architectural perspective. These industrial complexes represent a level of architectural and technical quality – broadly understood – that far exceeded the domestic average of the era. The quality-oriented and visionary client found a fitting professional partner in Győriterv’s architect, József Lőrincz. The halls, unprecedented in their time in both scale, formal and functional clarity, stand as exemplary cases of the exceptionally well-coordinated application of architectural and engineering knowledge. Owing to their success, similar facilities were also built for other actors in the Hungarian machinery industry. These buildings are of significance not only because of their industrial function, but also due to the role they played during the economic restructuring at the time of the regime change, forming a built legacy that remains in active use to this day. In addition to a brief overview of the factories themselves, the study focuses on the history of their construction – and in some cases, their design – while also outlining certain institutional aspects of the two socialist-era state-owned enterprises. The rich photographic documentation serves as a kind of time capsule, depicting how this industrial giant once looked and functioned. The primary sources of the research include archival materials, company publications, articles from the daily and professional press, as well as oral history interviews and an unpublished manuscript.

Finite Element Modeling of Different Autonomous Truck Combinations, Tire Types and Lateral Wander Modes

Mohammad Fahad

Publication Name: Applied Sciences Switzerland

Publication Date: 2026-03-01

Volume: 16

Issue: 5

Page Range: Unknown

Description:

Autonomous trucks can be used in different loading combinations, including different axle configurations, tire types, and lateral wander mode scenarios. In this research, four different truck types have been selected with varying gross weights and axle configurations. The four different truck types include a 5-axle long-haul semi-truck, a 6-axle electric autonomous truck, a 6-axle autonomous truck platoon leader, and a 5-axle autonomous truck platoon follower. Furthermore, three different tire footprint scenarios, consisting of a conventional dual wheel assembly, a wide base tire, and a new generation wide base tire, have been used. In order to utilize the possibility of lateral wander programmed into the autonomous trucks, three different lateral wander models, including zero lateral wander, a human-driven probabilistic lateral wander, and an optimum uniform wander mode, have been used. Finite element analysis has been employed to incorporate the effects of various scenarios on a conventional pavement section. Results showed improved pavement life with the use of uniform wander mode, where trucks T1 and T2 improved the pavement life by 47% and 56%, respectively, when compared to truck T3. Furthermore, the use of uniform wander mode decreases rutting and fatigue damage by 36% and 28%, respectively, on average for all scenarios. The use of new generation wide-base tires is recommended, since it reduces damaging strains by 38% when compared to the dual tire configuration.

A Learning Factory Environment for Human–Robot Collaboration-Based Remanufacturing Supported by Artificial Intelligence Solutions

Imre Paniti Zsolt Kemény Mátyás Hajós János Nacsa

Publication Name: Lecture Notes in Networks and Systems

Publication Date: 2025-01-01

Volume: 1546 LNNS

Issue: Unknown

Page Range: 296-303

Description:

In contrast to one-way assembly of products, simple disassembly and more complex remanufacturing present additional challenges and unknowns on several levels, often requiring human capabilities to be combined with machines—thereby becoming a rewarding deployment field for human–robot collaboration, supported by artificial intelligence, advanced planning and extended reality for improved human–machine interrelations. While the industry has realized little benefit of these—still evolving—areas, learning factories can contribute to closing gaps in skills and mindset of future engineers likely to actively shape the aforementioned fields at the time they begin to notably penetrate industrial production. The paper proposes an approach for building up a portfolio of learning factory resources supporting students in acquiring and independently refining knowledge and practice related to collaborative remanufacturing. The paper presents an incremental approach extending manufacturing knowledge to diagnostics and disassembly in collaborative environments, with an outlook on more comprehensive remanufacturing.

Tribological Properties of Nano-Sized ZrO2 Ceramic Particles in Automotive Lubricants

Rajmund Kuti D. Tóth I. Szabó

Publication Name: Fme Transactions

Publication Date: 2021-01-01

Volume: 49

Issue: 1

Page Range: 36-43

Description:

The demand for decreasing CO2-emission and harmful material content of the exhaust gas of passenger cars requires the improvement of the entire powertrain including the applied lubricants. One of the possible future engines lubricant can be the nano-sized ceramic particles, which can provide positive tribological properties also in the presence of nonmetallic surface materials. This paper presents the experimental investigation of ZrO2 nanoceramic powder as a lubricant additive. The tribological performance of the lubricant samples was experimentally investigated on a ball-on-disc translation tribometer. An optimum concentration was found at 0.4 wt%, where the wear scar diameter on the ball specimen was reduced by more than 40% compared to the reference sample. The SEM-analysis confirmed the mending mechanism theory: nanoparticles were revealed to aggregate between the asperities resulting in a significantly smoother contact surface.

Defining daily space use patterns in Hungary: identification of functional urban centres with a multidimensional methodology

Tibor Navracsics Katalin Mezei Judit Berkes Gábor Mayer Kristóf Bertalan Orbán

Publication Name: Regional Statistics

Publication Date: 2026-01-01

Volume: 16

Issue: 3

Page Range: 521-547

Description:

Some of the literature on catchment areas offers valuable insights into spatial units defined by the various types and functions of urban centres. In addition, a range of functional urban region delineation methodologies contribute significantly to understanding citizens' commuting habits. However, while the former often lacks a complex, multifunctional perspective, the latter typically focuses on labour market areas linked to global megacities. As a result, smaller centres fulfilling a wide range of everyday functions are frequently omitted from regional maps, and they remain hidden in the catchment area of larger cities. This research aims to address these gaps by proposing a method for identifying urban centres on the basis of multidimensional selection criteria. This approach enables the general mapping of their multifunctional catchment areas and their wider functional urban zones. This analysis extends the range of statistics commonly used: in addition to labour market commuting, it includes commuting for general and vocational education, as well as accounting for the accessibility of everyday commercial centres and frequently used urban-level public services. Owing to differing spatial organizing principles, this research highlights that everyday centres take on varied structural forms – justifying a multidimensional mapping approach that is in addition to traditional labour market commuting analyses. Although this study is grounded in the Hungarian context, its multidimensional approach to mapping functional urban catchment areas offers valuable insights and a flexible framework for international research. By integrating a wide range of everyday spatial behaviour indicators, this analysis not only deepens our understanding of urban networks but also provides urban planning and regional development professionals with a robust tool for identifying gaps in public service provision. In doing so, it can help increase access to essential services, particularly for residents in rural areas far from major urban centres, which are typically the focus of the literature.

Publication Name: Food Chemistry

Publication Date: 2025-01-01

Volume: 462

Issue: Unknown

Page Range: Unknown

Description:

β-conglycinin (β-CG) is a prominent storage protein belonging to the globulin family in soybean (Glycine max) seeds. Along with other soybean proteins, it serves as an important source of essential amino acids and high-quality nutrition. However, the digestibility and nutritional value of β-CG are key factors affecting the nutritional profile of soy-based foods. The heterotrimeric, secondary, and quaternary structures of β-CG, particularly the spatial arrangement of its α, α’, and β subunits, influence its functional properties. Considering these aspects, β-CG emerges as a significant protein with diverse applications in the food and health sectors. Therefore, this review explores β-CG's composition, structure, function, health implications, and industrial uses. Salient discussions are presented on its molecular structure, nutrition, digestibility, allergenicity, and techno-functions including emulsification, solubility, gelling, and structure–function complexities. Overall, the multifaceted potential of β-CG in the healthcare sector and the food industry is evident.

The use and abuse of legal history. On the nature of the censorial regimen morum

Gergely Deli

Publication Name: Journal on European History of Law

Publication Date: 2021-01-01

Volume: 12

Issue: 1

Page Range: 138-144

Description:

The paper analyses the nature of enforcement within the censorial regimen morum (CRM) in Ancient Rome by taking into consideration various Latin legal and literary sources. It comes to the conclusion that CRM could be seen as a transitional institution in a system which evolved from a formerly domaninant collective or decentralized to a more centralized enforcement. It also enriches the debate on the concept of law through historical insights by claiming that a social order can meaningfully called a legal order only if centralized production and enforcement of norms had been already added to the consensus of some commonly shared values.

Innovative Use of Concrete Canvas for Reinforcing Railway Substructures: Enhancing Load-Bearing Capacity and Stability

Szabolcs Fischer B. Eller

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2026-01-01

Volume: 23

Issue: 1

Page Range: 71-90

Description:

This study investigates the application of Geosynthetic Cementitious Composite Mats (GCCMs), specifically Concrete Canvas (CC), to reinforce railway substructures. Combining waterproofing, durability, and ease of installation, CC addresses challenges in ballasted railway tracks, such as local failures, moisture, and dynamic forces. The research fills a gap in the literature on CC's dynamic performance and its comparison to geogrids. Experimental methods, including shear box and static plate load tests, revealed that CC increases load-bearing capacity by up to 72% and improves shear resistance through its semi-rigid interlocking mechanism. Robust under dynamic forces, CC ensures stability without deformation. Compared to geogrids, CC offers similar reinforcement, with added benefits like easier hydration and installation. The study concludes that CC is a cost-effective solution for reinforcing railway substructures and improving load distribution and stability. Future research should address environmental impact and integration with advanced materials for enhanced performance and sustainability.

Economic development and growth in central and Eastern Europe

Csilla Polster

Publication Name: Comparative Economic Research

Publication Date: 2021-01-01

Volume: 24

Issue: 4

Page Range: 69-84

Description:

The study investigates the economic growth in Central and Eastern Europe in the last 25 years. The economy can be regarded as a substantial topic in any country, but it is even more interesting in developing countries. One of the basic ideas of the European Union is the convergence between member states, namely the reduction of development disparities, which can be achieved through faster economic growth in less-developed countries. Growth theory is one of the main topics in economics. Its significant importance is because the desire for development is one of the main driving forces of mankind. The aim of the study is to reveal the crucial differences and common features between the growth paths of the eleven Central and Eastern European member states of the European Union. After presenting growth theories, the growth performance of the examined Central and Eastern European member states is pinpointed. During the research, GDP per capita, population, migration, activity rate, employment rate, unemployment rate, foreign direct investment and foreign trade openness are considered.
