János Szép Kitti Karolyfi G. Hajdú Kira Rodaeva

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Page Range: 13-18

Description:

Although designing a structure is an iterative process by nature, a very limited number of iterations can be done with the traditional methods to reach the near-optimal solution. However, with the development of information technologies, the usage of parametric design in the construction industry has expanded. This paper aims to show the potential benefits of implementing parametric design and optimization techniques in the early structural design process. For this purpose, a simple parametric model of a steel frame with a truss roof system was created and then optimized for minimum mass and a given floor area. The case study demonstrated that the application of parametric design can reduce the Global Warming Potential of the structure by 7.6 % by optimizing the geometry and the cross-sections, leading to a more sustainable solution.

The Assessment of Economic Performance in the Sustainability Reports of Financial Institutions

Katatlin Vargáné Kiss

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 511-516

Description:

Sustainability reporting has gained worldwide importance for corporations over the past decade. This required the development of frameworks and standards for consistent disclosure. Non-financial or triple-bottom-line reporting reveals how firms, in general, incorporate SDGs in their reports and in what way they are assessed in terms of importance. While earlier sustainability issues were an integral part of the CSR activities published in the annual reports, these days, they are issued as separate reports due to the increased attention of stakeholders. Regarding financial institutions, the focus has gradually shifted from profitability issues to responsible investment and sustainable finance. Based on the content analysis of the most recent sustainability reports of the largest commercial banks in Hungary, including also the subsidiaries of foreign parent banks, the paper aims to provide a comprehensive overview of their economic impacts. Comparing the reports based on qualitative content analysis, the paper attempts to illustrate to what extent they comply with the GRI standards, what material topics are given priority in their reporting, and which sustainable development goals (SDGs) enjoy preference. The results obtained underpin the fact that, as opposed to sectors other than finance, sustainability endeavours related to economic growth are at the forefront compared to social and environmental issues.

Description:

Evaluation is an essential part of education. In addition to helping track student progress and learning processes, evaluations play a significant critical and important role in developing the individual's personality and forming a realistic self-image. Therefore, evaluations must be accurate, reliable, encompassing of changes, and supportive of developmental paths. Assessments can take various forms and can be carried out in-person, verbally, in writing, or through practical tasks, but they can also be conducted online, in a digital format, within a suitable framework. Regardless of these, one common element, the assessing educator is the adult who plans, integrates, and conducts the periodic control and evaluation process. Thus, there is also a generational difference inherently present and this affects the entire teaching and learning process, thereby influencing the evaluation process significantly, and reducing its efficiency. In this study, we present a self-developed system that increases the efficiency of the control and evaluation process by assisting the educator's work and reducing the communication gap due to generational differences. In addition to describing the applied technologies during the system's demonstration, we also discuss the methods and operating processes, which we conclude by evaluating the test results.

Influence of green human resource management on employees’ behavior through mediation of environmental knowledge of managers

Udaya Raj Paudel Niranjan Devkota Agnieszka Lopatka Ujjwal Bhattarai Péter Németh

Publication Name: Journal of International Studies

Publication Date: 2023-01-01

Volume: 16

Issue: 3

Page Range: 56-77

Description:

Lately, there has been a rising awareness of the significance of becoming green and applying different environmental management strategies within the corporate community. This paper endeavours to explore the adoption of Green HRM practices by managers in Patan Industrial Estate. This study addresses the importance of knowledge development in relation to HRM practices and employee behavior. The goal is to see how Green HRM influences EGB in Patan Industrial Estate through mediation of managers' environmental knowledge. Exploratory research design was chosen as the primary study paradigm to determine the truth. The data was evaluated quantitatively by using both descriptive and inferential statistics. The associations between the 113 replies were analyzed using SEM. According to the findings of the study, environmental knowledge does not operate as a facilitator between Green HRM and EGB. This result is also theoretically significant in terms of the AMO theory. However, Green HRM is an emerging concept that deserves more attention. Employees and organizations must make even more changes to ensure that greening processes are implemented in all of their activities. General recommendations for successful implementation of Green HRM practices include revising the vision, mission and organization policies of an organization, ensuring its ISO certification, advancement of technologies, and enhancing GHRM practices by providing training and empowering employees, as well as participating in proactive government initiatives.

Computer-Aided Planning of Radial and Diameter Routes in Local Public Transport Networks

Agoston Winkler

Publication Name: Eurasia Proceedings of Science Technology Engineering and Mathematics

Publication Date: 2023-01-01

Volume: 23

Issue: Unknown

Page Range: 165-172

Description:

Local public transport network planning is a complex procedure affected by many aspects (e.g., city structure, travel needs, the budget for the service, vehicle types, service frequencies, timetable optimization of parallel routes etc.). Due to the high number of possible solutions, finding the optimum is usually a problem with NP computational complexity. Although an extensive toolkit is available for evaluating specific networks, the number of versions that can be realistically examined and compared is highly limited. This implies that the routine and creativity of the network planning specialists play an important role in the selection of the examined networks. However, in some special cases, the search space can be narrowed so that all network versions can be automatically generated and compared. This paper presents such a case: when applying radial and diameter routes only, the main question is which directions should be connected to each other as a diameter route, or left alone as a radial line. The algorithm is presented on the example of the city Győr.

A Novel Feedback Linearisation Control of Flyback Converter

Miklós Kuczmann Miklos CSIZMADIA

Publication Name: Power Electronics and Drives

Publication Date: 2023-01-01

Volume: 8

Issue: 1

Page Range: 74-83

Description:

This paper presents a novel approach for feedback linearisation in a continuous conduction mode (CCM) of the flyback converter. Due to the unstable zero dynamics, a flyback converter has highly non-linear behaviour. Flyback converters mostly use the indirect (current) control mechanism. In contrast, this paper shows a direct control of the output voltage of a flyback converter with feedback linearisation (a non-linear control method). In the designed controller, an error integrator is applied to improve the dynamic and steady-state behaviour of the controller. To design the feedback linearisation method, the state-space averaged model is determined. The converter and the proposed control are tested in a MatLab/Simulink environment, and the results are compared with other optimal controller methods. The results provide feedback about the efficiency and practical implementation of the proposed method.
