Péter Németh Ben Neila Safwen

Publication Name: Acta Technica Jaurinensis

Publication Date: 2021-11-24

Volume: 14

Issue: 4

Page Range: 577-598

Description:

In this paper, we will specify our research on the impact of the COVID19 on Supply Chain Management and show up the critical issues and how the digital solution like the Physical Internet (PI, π) could solve the disruptions of production or delivery of a Supply Chain. The Physical Internet is still an emerging phenomenon in which it is intended to replace the current logistics model by encompassing new technologies such as Artificial Intelligence, Big Data, the Internet of Things (IoT), and others. This article aims to compose conceptual research to describe Supply Chain Management problems during the COVID-19 pandemic and represent the Physical Internet as a solution for this disruption based on various journal articles, papers, websites, and managers' experiences. Further, this study helps increase the understanding of scholars and practitioners on how the novel PI paradigm can solve COVID-19-induced Supply Chain disruptions. Furthermore, the Physical Internet and other modern technologies in the business world are necessary and recommended, as these current issues now require quick decisions and up-to-date knowledge.

Parliamentary inquiries as minority rights: are legal transplants possible?

Zsolt Szabó

Publication Name: Theory and Practice of Legislation

Publication Date: 2024-01-01

Volume: 12

Issue: 1

Page Range: 55-72

Description:

Committees of inquiry, in related literature, are often called as ‘sharpest sword’ of the opposition. However, this sharpness is highly dependent on how much rights the opposition is effectively provided by the fine details of the procedural rules, and whether these rights are justiciable. According to the German model, the inquiry must be launched if a quarter of the MPs require it, and the opposition enjoys minority rights also during the inquiry. Many countries implemented the first, but not the second element in their parliamentary procedures (Hungary, Kosovo, Albania, Lithuania), which led to ineffective inquiries. The only positive example for a successful transplant of the mandatory minority initiative for launching an inquiry is the neighbouring country, Austria. In most of the other countries, the majority is more effective in conducting inquiries, and, lacking judicial remedies, the opposition cannot put its right to inquiry in practice effectively. It seems that the mandatory minority initiative hardly works properly outside its original home country, Germany, and the only successful transplant country, Austria. Another evidence that legal transplants cannot survive if the legal environment and culture is not fertile and developed enough.

RELATIONSHIP BETWEEN DYNAMIC CAPABILITY VIEW AND ORGANIZATIONAL RESILIENCE: FINDINGS FROM A SYMMETRIC APPROACH

Laszlo Vasa Ali Shojaee

Publication Name: Problems and Perspectives in Management

Publication Date: 2024-01-01

Volume: 22

Issue: 4

Page Range: 671-682

Description:

The COVID-19 outbreak has underscored the importance of strengthening an organization’s resilience and adaptive capability. In emerging and uncertain conditions, firms must adopt new capabilities to develop and survive unstable and unforeseen crises. The purpose of this study is to examine the difference between organizational resilience and the antecedents that are validated using a quantitative survey. The respondents consist of 157 top employees from 21 private service firms at the managerial level in Bangladesh. The proposed relationship is measured using the partial least squares structural equation modeling (PLS-SEM), a symmetric approach, using SmartPLS 4 software. The findings help to produce the path coefficient with organizational resilience that can lead to sustainable environments in highly turbulent conditions. The PLS-SEM analysis indicates that the antecedents of flexibility, agility, and redundancy have a strong and meaningful association with organizational resilience in response to disruptions. Therefore, this paper shows evidence that the measurement scales more effectively account for uncertainty in achieving resilience, supporting the role of the dynamic capability view.

Effect of dietary butyrate supplementation on the production performance and parasitology of growing rabbits

Zsolt Gerencsér Zsolt Matics Zoltán Német Balázs Húth Csongor Demeter Anett Demeter-Jeremiás Róbert Juráskó Máté Sándor András Mayer

Publication Name: Bio Web of Conferences

Description:

The effect of a dietary butyrate supplementation on the production of fattening rabbits was examined. The control group (n=70 rabbits) was fed with granulated diet whereas the diet of butyrate group (n=70 rabbit) was supplemented with 0.2% of butyrate. The mortality rate was examined on a larger population (n=1050 rabbits/group). Butyrate group had lower weight gain at the ages of 46-52 and 60-66 days (-20 and - 17 %, respectively; P>0.001) but higher weight gain at 53-59 days of age (+13%; P<0.05). Butyrate group consumed less feed than the control group between 38-45, 46-52 and 60-66 days (-2.4%, P<0.001; -5.7%, P<0.01; - 4.9%, P<0.05, respectively). The feed conversion ratio of the butyrate group was worse between 46-52 days of age (+19%; P<0.01) but favourable at the ages of 53-59 and 67-73 days (-15% and -9%, respectively; P<0.05). Concerning the whole fattening period the weight gain, the feed intake and the feed conversion ratio of the groups did not differ. In the larger examined population, 4.0% and 6.3 % mortality was observed in the control and butyrate groups, respectively. The parasitological tests resulted only negative samples independently of groups. It can be concluded that dietary butyrate supplementation has not improved the performance of the growing rabbits.

Effects of soil compaction on cereal yield: A review

G. Milics A. J. Kovács A. Nyéki M. Neményi

Publication Name: Cereal Research Communications

Publication Date: 2017-03-01

Volume: 45

Issue: 1

Page Range: 1-22

Description:

This paper reviews the works related to the effect of soil compaction on cereal yield and focuses on research of field experiments. The reasons for compaction formation are usually a combination of several types of interactions. Therefore one of the most researched topics all over the world is the changes in the soil's physical and chemical properties to achieve sustainable cereal production conditions. Whether we are talking about soil bulk density, physical soil properties, water conductivity or electrical conductivity, or based on the results of measurements of on-line or point of soil sampling resistance testing, the fact is more and more information is at our disposal to find answers to the challenges. Thanks to precision plant production technologies (PA) these challenges can be overcome in a much more efficient way than earlier as instruments are available (geospatial technologies such as GIS, remote sensing, GPS with integrated sensors and steering systems; plant physiological models, such Decision Support System for Agrotechnology Transfer (DSSAT), which includes models for cereals etc.). The tests were carried out first of all on alteration clay and sand content in loam, sandy loam and silt loam soils. In the study we examined especially the change in natural soil compaction conditions and its effect on cereal yields. Both the literature and our own investigations have shown that the soil moisture content changes have the opposite effect in natural compaction in clay and sand content related to cereal yield. These skills would contribute to the spreading of environmental, sustainable fertilizing devoid of nitrate leaching planning and cereal yield prediction within the framework of the PA to eliminate seasonal effects.

Extension of the Energetic Modeling of a Single-Stage Gear Unit to a Multi-Stage Constant Ratio Gear Unit †

József Polák

Publication Name: Engineering Proceedings

Publication Date: 2025-10-01

Volume: 113

Issue: 1

Page Range: Unknown

Description:

The difficulty in designing gears to be installed in electric vehicles is caused by the fact that the efficiency of gears is generally treated as a constant value in the entire operating range, while these show significant differences in different operating ranges; therefore, it is necessary to examine the energy and efficiency of the gear, and to create a mathematical model, which can be optimally fitted into the vehicle’s drivetrain in terms of energy. I have performed this modeling in previous years for a single-stage gear unit. However, this model encounters physical limitations, since a larger gear ratio modification cannot be performed in one stage; the number of stages must be increased as the gear ratio increases. As the number of stages increases, the structure of the mathematical model changes, as changes to the gear unit must be incorporated into the model. In this article, an extension of the mathematical model of the gear unit is presented.

Households’ electricity consumption in hungarian urban areas

Szigeti Cecília Judit Berkes Ferenc Bakó

Publication Name: Energies

Publication Date: 2021-05-02

Volume: 14

Issue: 10

Page Range: Unknown

Description:

The aim of this study is to examine the factors influencing the electricity consumption of urban households and to prove these with statistically significant results. The study includes 46 small and medium-sized towns in Hungary. The methodology of the study is mainly provided by a model that can be used for this purpose; however, the results obtained with the traditional regression method are compared with the results of another, more complex estimation method, the artificial neural network, which has the advantage of being able to use different types of models. The focus of our article is on methodological alignment, not necessarily the discovery of new results. Certain demographic characteristics significantly determine the energy demand of a household sector in a municipality. In this case, as the ratio of people aged 60 or over within a city rises by 1%, the urban household average energy consumption decreases by 61 kilowatt hours, and when it rises by 1%, the amount of pollutants expelled from urban households’ average energy consumption may decrease by 22.8745 kg. The research area of our paper was greatly influenced by the availability of the statistical data. The results can be used in the planning of urban developments.

Evaluating Seismic Vulnerability of Residential Buildings by Rapid Evaluation Method (REM)

Parves Sultan Orsolya Kegyes-Brassai Md Faiz Shah Anas Ahmed

Publication Name: Future of Business and Finance

Publication Date: 2021-01-01

Volume: Part F9822

Issue: Unknown

Page Range: 541-552

Description:

Increased urbanization of a city may create a higher seismic risk. This study investigates Jeddah city, rapidly expanding in the number of buildings and population, to address the rapid evaluation of residential buildings using the rapid evaluation method (REM) to assess building stock to determine hazard and evaluate vulnerability through the scoring method from FEMA 155. Two districts were selected based on a cluster analysis of population and building data. One is a developing urbanized area, and the other is a traditional area. This offers a possibility to compare the vulnerability of buildings constructed according to different seismic codes and to make assumptions about the rest of the city based on typical structures. The basic structural score was determined considering the building structure and moderate seismicity of the region using score modifiers, e.g. vertical irregularity and soil score modifier, assuming sabkhas. The result of the investigation shows different levels of vulnerability and areas where intervention is needed.

Some variants of the method of fundamental solutions: Regularization using radial and nearly radial basis functions

Csaba Gáspár

Publication Name: Central European Journal of Mathematics

Publication Date: 2013-08-01

Volume: 11

Issue: 8

Page Range: 1429-1440

Description:

The method of fundamental solutions and some versions applied to mixed boundary value problems are considered. Several strategies are outlined to avoid the problems due to the singularity of the fundamental solutions: the use of higher order fundamental solutions, and the use of nearly fundamental solutions and special fundamental solutions concentrated on lines instead of points. The errors of the approximations as well as the problem of ill-conditioned matrices are illustrated via numerical examples. © 2013 Versita Warsaw and Springer-Verlag Wien.
