Miklós F. Hatwágner Gergely Mikulai Mehran Amini Laszlo T. Koczy

Publication Name: Infocommunications Journal

Publication Date: 2021-01-01

Volume: 13

Issue: 3

Page Range: 14-23

Description:

Fuzzy cognitive maps (FCM) have been broadly employed to analyze complex and decidedly uncertain systems in modeling, forecasting, decision making, etc. Road traffic flow is also notoriously known as a highly uncertain nonlinear and complex system. Even though applications of FCM in risk analysis have been presented in various engineering fields, this research aims at modeling road traffic flow based on macroscopic characteristics through FCM. Therefore, a simulation of variables involved with road traffic flow carried out through FCM reasoning on historical data collected from the e-toll dataset of Hungarian networks of freeways. The proposed FCM model is developed based on 58 selected freeway segments as the “concepts” of the FCM; moreover, a new inference rule for employing in FCM reasoning process along with its algorithms have been presented. The results illustrate FCM representation and computation of the real segments with their main road traffic-related characteristics that have reached an equilibrium point. Furthermore, a simulation of the road traffic flow by performing the analysis of customized scenarios is presented, through which macroscopic modeling objectives such as predicting future road traffic flow state, route guidance in various scenarios, freeway geometric characteristics indication, and effectual mobility can be evaluated.

Does the demographic dividend with human capital development yield an economic dividend? Evidence from Central Asia

Muyassar Kurbanova Eva Berde

Publication Name: Post Communist Economies

Publication Date: 2023-01-01

Volume: 35

Issue: 2

Page Range: 154-178

Description:

Both fertility and mortality rates are declining in the five Central Asian countries, so far resulting in an increasingly working-age population. The main question is whether these countries can benefit from this demographic transition while having different economic structures and diverse ethnicities. Our article shows the importance of demographic, economic, and human capital indicators and the influential role of governance indicators such as the Political Corruption Index and Egalitarian Democracy Index for economic growth. Based on the data from 1991 to 2018, the analysis has been conducted by employing fixed effect estimation with Driscoll-Kraay standard errors. The findings indicate that human capital with proper education and an appropriately absorbed labour force does have a more powerful effect on the demographic benefit. In addition, improving the quality of governance has a significant impact on economic growth.

EXAMINING THE VISIBILITY OF SOCIAL RESPONSIBILITY ON THE WEBSITES OF HUNGARIAN STATE UNIVERSITIES

Adrienn Reisinger Zsolt Dános

Publication Name: Deturope

Publication Date: 2021-01-01

Volume: 13

Issue: 3

Page Range: 58-72

Description:

The paper investigates university social responsibility at Hungarian universities by examining their websites. Although the concept of university social responsibility has existed for nearly 20 years, the scope of its research and theoretical literature still falls far short of that of corporate social responsibility. There is extant literature on the topic including case studies from around the world showing the importance of university social responsibility. Nevertheless, the scope of thematic analysis of the topic is very narrow with only a few pieces of comprehensive systematic research published so far, and the theoretical literature only highlights the work of some major researchers. Due to the complexity of the topic, the amount of previous literature attempting to explore the effects of university social responsibility is also limited. The aim of this paper is to investigate how terms relating to social responsibility appear on the websites of Hungarian universities. In autumn 2019 research was carried out involving twenty-one universities. The paper analyses how social responsibility is visible on university websites based on given keywords. The research employed quantitative content analysis. The hypothesis was that based on visibility the same university categories can be formed according to the size and profile of the institutions. According to the authors’ present knowledge no such research has been carried out in Hungary so far. There are some university website researches in different countries but with different purposes with the special focus on sustainability. So the method of the present research is an attempt to find out how to measure the social responsibility visibility of universities and how to make categorizations based on the analyses. The limitation of the research is, among others, that universities have different search engines on their websites, which can lead to the misinterpretation of results. The main findings are that the visibility of social responsibility based on website analyses depends not only on the size and profile of the institutions; therefore, the investigation of visibility can contribute to the creation of new categories proving that social responsibility is far beyond the size or profile of the universities. The findings can help institutions develop the conscious communication of their social responsibility activity, and provide assistance to the research community.

Steady-Speed Traffic Capacity Analysis for Autonomous and Human-Driven Vehicles

Balázs Horváth Dilshad Mohammed

Publication Name: Applied Sciences Switzerland

Publication Date: 2024-01-01

Volume: 14

Issue: 1

Page Range: Unknown

Description:

As the automotive industry transitions towards the era of autonomous vehicles, it is imperative to assess and compare the following distances maintained by vehicles equipped with adaptive cruise control (ACC) systems against those of traditional human-driven vehicles. This study aims to provide insights into the future use of autonomous vehicles by empirically examining the following distances achieved under different driving conditions. Controlled experiments were conducted using three vehicles equipped with various types of ACC sensors, and comparable scenarios were replicated with human drivers. The experiments involved driving at multiple constant speeds to evaluate the efficacy of ACC in maintaining safe following distances. Our findings indicate that ACC systems consistently converge on optimal following distances, demonstrating their ability to regulate spacing between vehicles effectively. However, a notable downside emerged in terms of their adverse impact on road capacities, where the results indicate a mitigation in capacity percentages of 7.6%, 9.3%, and 15.6% for the three types of ACC-equipped vehicles compared to human drivers. This study sheds light on the intricate interplay between ACC systems and human driving behaviors, emphasizing the need to consider both factors when envisioning the future of autonomous vehicles. While ACC systems provide a standardized and reliable approach to following distances, the shorter distances observed in human-driven scenarios suggest a potential trade-off between safety and traffic capacity. These insights contribute to a comprehensive understanding of the dynamics involved in autonomous driving, facilitating informed decision making for the integration of autonomous vehicles into future transportation systems.

Categorisation of SDG targets into ESG pillars based on ESRS taxonomy

Árpád Tóth Péter Molnár Bence Lukács

Publication Name: Discover Sustainability

Publication Date: 2026-12-01

Volume: 7

Issue: 1

Page Range: Unknown

Description:

This study examines the alignment between the Sustainable Development Goals (SDGs) and the Environmental, Social, and Governance (ESG) pillars through the lens of the European Sustainability Reporting Standards (ESRS) taxonomy, complemented by the Global Reporting Initiative (GRI). The research introduces a policy-relevant framework that categorizes SDG targets within ESG pillars, offering structured guidance for policymakers and regulatory bodies to harmonize global sustainability goals with corporate reporting practices. By mapping 199 GRI and 201 ESRS accounting entries to the 17 SDGs, the study identifies significant opportunities to address thematic and procedural gaps in existing reporting systems. The findings demonstrate that SDG 8 (“Decent Work and Economic Growth”) exhibits the highest linkage rate to ESRS accounting items, reinforcing its relevance for policy-driven frameworks that integrate economic resilience with social equity. This harmonized approach underscores the role of policy in fostering alignment between corporate ESG strategies and broader sustainability objectives, mitigating greenwashing risks, and advancing standardization across regions and sectors. The study advocates for policy interventions that leverage this framework to enhance transparency, accountability, and long-term decision-making for sustainable development.

A Canonical Set of Operations for Editing Dashboard Layouts in Virtual Reality

Adam B. Csapo Tarek Setti

Publication Name: Frontiers in Computer Science

Description:

Virtual reality (VR) is a powerful technological framework that can be considered as comprising any kind of device that allows for 3D environments to be simulated and interacted with via a digital interface. Depending on the specific technologies used, VR can allow users to experience a virtual world through their different senses, i.e., most often sight, but also through touch, hearing, and smell. In this paper, it is argued that a key impediment to the widespread adoption of VR technology today is the lack of interoperability between users’’ existing digital life (including 2D documents, videos, the Web, and even mobile applications) and the 3D spaces. Without such interoperability, 3D spaces offered by current VR platforms seem empty and lacking in functionality. In order to improve this situation, it is suggested that users could benefit from being able to create dashboard layouts (comprising 2D displays) for themselves in the 3D spaces, allowing them to arrange, view and interact with their existing 2D content alongside the 3D objects. Therefore, the objective of this research is to help users organize and arrange 2D content in 3D spaces depending on their needs. To this end, following a discussion on why this is a challenging problem—both from a scientific and from a practical perspective—a set of operations are proposed that are meant to be minimal and canonical and enable the creation of dashboard layouts in 3D. Based on a reference implementation on the MaxWhere VR platform, a set of experiments were carried out to measure how much time users needed to recreate existing layouts inside an empty version of the corresponding 3D spaces, and the precision with which they could do so. Results showed that users were able to carry out this task, on average, at a rate of less than 45 s per 2D display at an acceptably high precision.
