Energy absorption modelling technique for car body deformation

Istvan A. Harmati András Rövid Peter Varlaki

Publication Name: Saci 2007 4th International Symposium on Applied Computational Intelligence and Informatics Proceedings

Publication Date: 2007-10-01

Volume: Unknown

Issue: Unknown

Page Range: 269-272

Description:

The main object of this paper is to introduce a model for describing how the enrgy distribution changes during deformational processes, esp. in car crashes. This an important and difficult task in accident analysis and in safety car-body design. Exact estimation or measuring of the absorbed energy by the deformation is almost impossible. The classical tool for this task is usually a differental equation based finite element method, which requires exact knowledge about the parameters and takes a lot of computational time with high complexity. In the following we introduce a simple numerical model for the changing of the energy distribution during the whole deformational process. © 2007 IEEE.

Vaporization Dynamics of a Dissipative Quantum Liquid

Ádám Bácsi Balázs Dóra Balázs Dóra Cǎtǎlin Paşcu Moca Gergely Zarand

Publication Name: Physical Review Letters

Publication Date: 2020-12-30

Volume: 125

Issue: 26

Page Range: Unknown

Description:

We investigate the stability of a Luttinger liquid, upon suddenly coupling it to a dissipative environment. Within the Lindblad equation, the environment couples to local currents and heats the quantum liquid up to infinite temperatures. The single particle density matrix reveals the fractionalization of fermionic excitations in the spatial correlations by retaining the initial noninteger power law exponents, accompanied by an exponential decay in time with an interaction dependent rate. The spectrum of the time evolved density matrix is gapped, which collapses gradually as -ln(t). The von Neumann entropy crosses over from the early time -tln(t) behavior to ln(t) growth for late times. The early time dynamics is captured numerically by performing simulations on spinless interacting fermions, using several numerically exact methods. Our results could be tested experimentally in bosonic Luttinger liquids.

Description:

This study assesses the effectiveness of seismic base isolation using triple friction pendulum isolators (TFPIs) as a retrofitting strategy for a five-story steel building. This building is characterized by vulnerable Satchel connections, which suffered extensive brittle failures during the 1990 Manjil and 2003 Bam earthquakes in Iran. Four different experimentally calibrated Satchel connection configurations (S1 to S4) were modeled within a typical five-story building. These configurations varied in parameters such as rotational stiffness (780t.m/rad to 1380t.m/rad), angle lengths (15 cm to 20 cm), and beam sections (IPE180 and IPE220). For each of the four building models, all connections were uniformly assigned one of the four specimen types. The structural and non-structural performance of these models was evaluated using nonlinear endurance time (ET) analysis. The assessment covered seismic hazard levels corresponding to 475-year, 2475-year, and return periods beyond 2475 years. The results showed that implementing a base isolation system avoids the need for extensive strengthening of the existing connections. Moreover, by adding the isolators to the current connections, the structure’s performance can significantly surpass that of a brand-new, code-compliant design.

Safeguarding natural environment in tourism—And the phenomenon of greenwashing

Ildikó Ernszt Viktória Kundi

Publication Name: Journal of Infrastructure Policy and Development

Publication Date: 2024-01-01

Volume: 8

Issue: 8

Page Range: Unknown

Description:

One of the important elements of corporate communication nowadays is to draw attention to the environmentally friendly and sustainable aspects of products and services. However, companies are profit-oriented, their goal is to win consumers and they are not afraid to get more passengers and more income by using green, often completely empty phrases. Despite the topicality of the subject, the need to examine the legal environment is indisputable. From a methodological point of view, this document presents a non-exhaustive list of the most relevant legislation and recommendations. This is also a novelty of the study, as the topic has not been examined from the legislative framework before. The purpose of our article is to present the phenomenon in the field of tourism, to shed light on the difficulties of the regulatory background of greenwashing. Many legal rules have been adopted to protect and safeguard the natural environment. In this article, we will look at some of the legal solutions and documents that attempt to serve this noble cause. All the international, EU and national standards that protect the environment are also relevant in the field of tourism. However, we will not go into these in this article. We will highlight a few standards which we believe may be of particular relevance in the context of tourism. Our selection is rather subjective, as there is no need for it to be exhaustive given the volume and complexity of the legislation, especially as all environmental elements are essential for tourism. As a result of the research, it can be concluded that despite the increasingly sophisticated regulation of the legal environment, there is evidence that companies are taking advantage of the opportunities offered by communication and consumer confidence, often through ignorance, to commit greenwashing.

Regional Patterns in Weed Composition of Maize Fields in Eastern Hungary: The Balance of Environmental and Agricultural Factors

Zita Dorner Mihály Zalai János György NAGY Erzsébet Tóth

Publication Name: Agronomy

Publication Date: 2025-08-01

Volume: 15

Issue: 8

Page Range: Unknown

Description:

The primary aim of this study was to explore the influence of abiotic factors on weed development in maize fields, with the goal of informing more effective weed management practices. We focused on identifying key environmental, edaphic, and agricultural variables that contribute to weed infestations, particularly before the application of spring herbicide treatments. Field investigations were conducted from 2018 to 2021 across selected maize-growing regions in Hungary. Over the four-year period, a total of 51 weed species were recorded, with Echinochloa crus-galli, Chenopodium album, Portulaca oleracea, and Hibiscus trionum emerging as the most prevalent taxa. Collectively, these four species accounted for more than half (52%) of the total weed cover. Altogether, the 20 most dominant species contributed 95% of the overall weed coverage. The analysis revealed that weed cover, species richness, and weed diversity were significantly affected by soil properties, nutrient levels, geographic location, and tillage systems. The results confirm that the composition of weed species was influenced by several environmental and management-related factors, including soil parameters, geographical location, annual precipitation, tillage method, and fertilizer application. Environmental factors collectively explained a slightly higher proportion of the variance (13.37%) than farming factors (12.66%) at a 90% significance level. Seasonal dynamics and crop rotation history also played a notable role in species distribution. Nutrient inputs, particularly nitrogen, phosphorus, and potassium, influenced both species diversity and floristic composition. Deep tillage practices favored the proliferation of perennial species, whereas shallow cultivation tended to promote annual weeds. Overall, the composition of weed vegetation proved to be a valuable indicator of site-specific soil conditions and agricultural practices. These findings underscore the need to tailor weed management strategies to local environmental and soil contexts for sustainable crop production.

Szilárd Rácz Ildikó Egyed Ádám Páthy Judit Berkes

Publication Name: Journal of Urban and Regional Analysis

Publication Date: 2025-01-01

Volume: 17

Issue: 1

Page Range: 5-35

Description:

Over the past three decades, significant socio-economic transformations have reshaped the post-socialist states of Central and Eastern Europe. This study examines the geography of firms with over 10 employees across 15 countries: Albania, Austria, Bosnia and Herzegovina, Bulgaria, Croatia, Czechia, Hungary, Kosovo, Montenegro, North Macedonia, Poland, Romania, Serbia, Slova-kia, and Slovenia. Using data from over 300,000 firms, the analysis focused on firm size categories, turnover, and activity distribution. The research highlighted disparities between post-socialist and other countries, and it employed descriptive statistics and the framework of agglomeration economies to uncover nuanced spatial patterns. The findings revealed significant differences in business concentration and the functions of small and medium-sized cities, particularly in the regions without a European-scale metropolis, emphasising their role in regional economic and demographic sustainability.

The impact of marketing strategy on logistics decisions and the implementation of JIT

Peter Foldesi Eszter Sós

Publication Name: Acta Technica Jaurinensis

Publication Date: 2021-11-24

Volume: 14

Issue: 4

Page Range: 364-376

Description:

Marketing has a significant impact on logistics systems and corporate performance, so it is nowadays necessary to define a marketing logistics strategy in the lives of larger companies so that logistics decisions are not distorted by the marketing strategy. According to the current direction of development, smaller and smaller quantities of goods are constantly being moved, with ever shorter deadlines. Therefore, companies prefer to use the Just In Time (JIT) system, which results in a gradual reduction in inventory costs, but increases the burden on the environment. In this article, we analyze the interaction between marketing and logistics and the logistics environment required to implement a JIT system. For research we have used the matrix of Quality Function Deployment (QFD) technique to evaluate the needs of the customer with respect to the JIT system, thus clarifying the logistics strategy applicable to the introduction of the specific product.

Description:

Introduction: Non-communicable diseases (NCDs) accounted for 74% of global deaths in 2024, with over 41 million people dying. The WHO has identified reducing behavioral and metabolic risk factors as a priority intervention. In modern healthcare, patient-centered care plays a key role by addressing individual needs, lifestyles, and motivations, thereby enhancing the effectiveness of prevention and behavior change. Food-based dietary guidelines (FBDG), such as Hungary’s OKOSTÁNYÉR®, are vital in prevention and medical nutrition therapy. However, the effectiveness of such dietary interventions largely depends on individuals’ health literacy. Objectives: This study aimed to explore the relationship between health literacy, dieting habits, dietary counseling, and awareness of the local FBDG recommendations. Methods: This cross-sectional study was conducted in February 2023 on a representative sample (N = 500) of the adult Hungarian population, using the CAWI method. Data were collected with the validated HLS-EU 47-item questionnaire and additional custom items on health status, dieting, and awareness of the local FBDG. Health literacy indexes were calculated using validated thresholds. Descriptive statistics, chi-square tests, ANOVA, and multivariate regression analyses were applied (p < 0.05). Results: A total of 77.4% of respondents had low (insufficient or problematic) health literacy. Higher education levels and younger age were significantly associated with better health literacy. Chronic diseases were more prevalent in low health literacy groups. About 32.4% of respondents followed a medically indicated diet, and 36.8% had received dietary counseling. Awareness of the local FBDG was relatively low (20.8%), particularly among men and those with lower education. Conclusion: Patient-centered care necessitates a high level of health literacy, enabling patients to actively participate in their therapy. Findings of the study highlight that low health literacy in the Hungarian population poses a major challenge to the success of dietary interventions. Targeted health communication strategies and tailored dietetic support are essential to improve the effectiveness of personalized nutrition care, particularly among vulnerable groups with limited health literacy.
