Driving Examiners’ Perceptions and Awareness of Advanced Driver Assistance Systems: A Survey-Based Analysis †

Boglárka Eisingerné Balassa Réka Koteczki

Publication Name: Engineering Proceedings

Publication Date: 2024-01-01

Volume: 79

Issue: 1

Page Range: Unknown

Description:

Advanced Driver Assistance Systems (ADASs) can have a significant role in contributing to road safety. However, technological innovations are gaining user acceptance at different rates, which is a key factor for their widespread deployment. In Hungary, learning about ADASs is not part of the curriculum in driving schools. In the present research, a questionnaire survey was conducted among driving examiners to assess their level of ADAS awareness. The results show that, in general, examining officers have a positive attitude towards the technology and are quite knowledgeable about it, compared to drivers. However, education and information are also essential for them, as there are few places to obtain credible information.

Brant von Goble

Publication Name: Engineering Proceedings

Publication Date: 2024-01-01

Volume: 79

Issue: 1

Page Range: Unknown

Description:

Due to their high fatality rate, motorcycles, often referred to as “donorcycles” in the U.S., present unique safety challenges. In Hungary, motorcycle safety remains a critical issue despite a relatively low per capita rate of motor vehicle deaths, largely due to limited ownership and recognition. This study examines historical trends in motorcycle use in Hungary and the economic factors influencing their current prevalence. By emphasizing the crucial role of helmets and safety gear, road conditions, and environmental factors, this paper provides actionable recommendations to improve motorcycle safety in Győr and the surrounding regions. Implementing these recommendations stands to significantly reduce accidents and save lives, ensuring safer roads for all.

Fuzzy search space for correction of cognitive biases in constructing mathematical models

Peter Foldesi Zs Dányádi Laszlo T. Koczy

Publication Name: 3rd IEEE International Conference on Cognitive Infocommunications Coginfocom 2012 Proceedings

Publication Date: 2012-12-01

Volume: Unknown

Issue: Unknown

Page Range: 585-589

Description:

In optimization the constructed mathematical models are very often idealized mappings of the actual problem. Considering human decision-making processes there is always a chance that cognitive biases occur when constructing the objective function and the constrains. Misrepresented human desires in the objective function or in the constrains result non-acceptable outcome for the decision-maker. To solve the problem of uncertainty concerning the search space we propose the use of fuzzy search space. Bacterial evolutionary algorithm is applied to demonstrate the difference between solutions with altering degree of satisfaction of the original constrains. By presenting the whole set of solutions to the human decision-maker the cognitive biases encoded into the mathematical model can be corrected. © 2012 IEEE.

Fuzzy signature based description of complex overtaking and engagement conflicts in railway traffic control

Gabor Rozsa Áron Ballagi Laszlo T. Koczy

Publication Name: IEEE AFRICON Conference

Publication Date: 2015-11-18

Volume: 2015-November

Issue: Unknown

Page Range: Unknown

Description:

The railway traffic system and its respective subsystems, especially station and timetable management are extremely large and complex systems comprising a multitude of complex structured data. The theoretical and pre-planned traffic control is calculating with idealized traffic situations, but the real life scenes often suffer from conflicts and deviations. The complex traffic conflict states include uncertain conditions and vagueness of information. Classical methods cannot work properly under these uncertain conditions. In this paper we propose a new approach to describe these complex conflict situations using fuzzy signatures for recognizing and describing traffic conflicts in a hierarchically structured manner.

EXAMINING THE CRITICAL SUCCESS FACTORS FOR THE EFFICIENCY OF GREEN ENERGY PROJECTS

Aknur Zhidebekkyzy Dalia Streimikiene Assel Kozhakhmetova Aizhan K. Anarkhan

Publication Name: Polish Journal of Management Studies

Publication Date: 2024-06-24

Volume: 29

Issue: 2

Page Range: 328-345

Description:

In recent times, there has been a remarkable exponential interest in green energy projects, driven by their potential to significantly decrease greenhouse gas (GHG) emissions and reduce reliance on fossil fuels. However, such high-tech projects' complexity, expensiveness, and high uncertainty level necessitate new ways of increasing efficiency. Therefore, this study, with its clear aim to evaluate the efficiency of green energy projects and identify the critical success factors that can enhance efficiency, remains a compelling and relevant research endeavour. The study employed a rigorous methodology, using multilinear regression analysis to survey 123 project managers from Kazakhstan. This allowed for a comprehensive comparison of the efficiency level of green energy projects and low-tech projects. Research results show that green energy projects exhibit the highest percentage of schedule overrun at 23.9% and cost overrun at 32.7%, indicating substantial delays in project completion and extra expenses in budget compared with low-tech projects. Moreover, green energy projects show the least favourable results (7.3) regarding technological performance. The study reveals the following critical success processes enhancing project efficiency: project planning, scope and cost management, communication, and team management. Based on the processes of the Project Management Body of Knowledge (PMBoK) Guide, an algorithm for managing green energy projects was developed. This tool equips project managers with a process-based map, enabling them to run their projects effectively and enhance their efficiency.

A common periodic table of codons and amino acids

Balázs Benyó G. Fordos J. C. Biro Ákos Szlávecz T. Micsik Z. Benyó C. Sansom

Publication Name: Biochemical and Biophysical Research Communications

Publication Date: 2003-06-27

Volume: 306

Issue: 2

Page Range: 408-415

Description:

A periodic table of codons has been designed where the codons are in regular locations. The table has four fields (16 places in each) one with each of the four nucleotides (A, U, G, C) in the central codon position. Thus, AAA (lysine), UUU (phenylalanine), GGG (glycine), and CCC (proline) were placed into the corners of the fields as the main codons (and amino acids) of the fields. They were connected to each other by six axes. The resulting nucleic acid periodic table showed perfect axial symmetry for codons. The corresponding amino acid table also displaced periodicity regarding the biochemical properties (charge and hydropathy) of the 20 amino acids and the position of the stop signals. The table emphasizes the importance of the central nucleotide in the codons and predicts that purines control the charge while pyrimidines determine the polarity of the amino acids. This prediction was experimentally tested. © 2003 Elsevier Science (USA). All rights reserved.

Application of chlorogenic acid in dairy product enrichment/fortification – a review

U. R. Chandimala Zsolt Ajtony

Publication Name: Lwt

Publication Date: 2025-09-15

Volume: 232

Issue: Unknown

Page Range: Unknown

Description:

Chlorogenic acid (CGA), also known as 5-O-caffeoylquinic acid, is one of the most abundant phenolic compounds in nature. CGA exhibits antioxidant, anti-inflammatory, anti-tumor, neuroprotective, cardiovascular, hepatoprotective, and metabolic regulatory properties. Due to the high usage of milk and fermented milk products, dairy becomes an excellent food source for CGA fortification, focusing on exploiting health benefits for consumers. An increasing trend exists in utilizing plant materials rich in CGA in dairy formulations to enhance dairy products' antioxidant profile and health-promoting potential. This review examines 58 recent studies on CGA incorporation into dairy products, focusing on their chemistry, biological activities, processing methods, and potential challenges for fortification. Extraction techniques such as microwave-assisted extraction and ultrasonic-assisted methods are preferred over conventional methods due to their efficiency and the quality of the extracts. In dairy formulations, thermal processing, high-pressure homogenization, controlled fermentation, and encapsulation techniques are critical for maintaining the stability and efficacy of CGA. Encapsulation with materials like β-cyclodextrin and chitosan nanoparticles enhances CGA stability during processing, storage, and digestion. This review emphasizes the significance of understanding CGA-protein interactions in dairy matrices, as these can either protect CGA from degradation or influence its bioavailability. The findings of this study underscore, in heat-treated and fermented dairy systems, that processing-induced CGA-milk protein interactions safeguard CGA from oxidative damage and improve CGA's bioaccessibility. Further research is needed to optimize CGA fortification strategies in dairy products to maximize their functional benefits.

Some areas where digital forensics can support the addressing of legal challenges linked to forensic genetic genealogy

Mónika Nogel

Publication Name: Forensic Science International Digital Investigation

Publication Date: 2024-06-01

Volume: 49

Issue: Unknown

Page Range: Unknown

Description:

Forensic genetic genealogy (FGG), also known as investigative genetic genealogy (IGG), produces investigative leads in criminal cases where unidentified DNA is discovered at the crime scene and does not match any profiles in criminal databases. It works by comparing crime scene DNA samples to public or private genealogical databases to identify potential familial relationships and narrow down suspects or identify unknown individuals. Although the fields of FGG and digital forensics (DF) work with different types of evidence and techniques, and consequently develop independently, they share several common characteristics. This study aims to demonstrate that despite their independent development and differences, the experiences of progress in DF field can be utilized in some respects, especially concerning the protection of the rights of the individuals concerned. The aim of this article is to outline some areas where DF can provide assistance in dealing with ethical and social challenges that FGG must address.
