Description:

The goal of this article is to examine traffic education and its examination system, using a new approach based on the House of Quality method. While every country has its own legal rules and requirements regarding how traffic education and examinations are conducted, there is a direct relationship between traffic education, its examination system and road safety. Therefore the quality of such a complicated process is of great interest for both stakeholders: the authorities and the citizens. These stakeholders both have their own objectives regarding the system, consequently increasing its complexity. This article investigates, as its case study, the system in Hungary. The House of Quality method has been expanded to provide a unique approach to examine the goals and objectives of both stakeholders, revealing similarities and differences and their interrelationships. Secondary data on the effectiveness of the traffic education and examination system are also analysed. Based on the HOQ model representations of the goals and objectives of the stakeholders regarding the traffic education and exam system, it can be established that the stakeholder points of view are closer to each other in the case of the test system than that of the education system. However, there are unsolved contradictions between the stakeholders that have to be handled, as opinions regarding the quality of the service and the criteria of the stakeholders’ satisfaction are very diverse.

One-at-a-time sensitivity study of a nonlinear fire truck suspension model

F. Hajdu Rajmund Kuti G. Y. Molnarka

Publication Name: Fme Transactions

Publication Date: 2020-01-01

Volume: 48

Issue: 1

Page Range: 90-95

Description:

In this paper the detailed OAT (one-at-a-time) sensitivity analysis of a nonlinear fire truck suspension system is carried out with numerical simulation. As output to measure sensitivity the RMS of acceleration was chosen, which can be calculated with numerical simulations easily. The degree of sensitivity was measured with a sensitivity index and based on it sensitivity Fuzzy-sets were established. The membership of each parameter to the Fuzzy sets is calculated and based on it, it was determined which parameters are the most sensitive. With the presented results it is shown that the proposed method is suitable for testing mathematical models as well.

Description:

Enhancing productivity, income, and food security requires agricultural services and skill development, especially in vulnerable areas like the Gaza Strip where farmers constantly confront obstacles. With an emphasis on the mediating function of farmers' knowledge, this study investigates the connections among household food security, skill development, and agricultural services. 379 farmers in the Gaza Strip were surveyed using a quantitative methodology. In order to examine the direct and indirect effects of agricultural services and skills on food security outcomes, data were gathered using structured questionnaires and analyzed using SPSS software. The findings show that farmers' knowledge and levels of food security are greatly and favorably impacted by agricultural services. It was discovered that having access to financial support, technical help, and agricultural inputs improved farmers' ability to provide food for their families. Additionally, learning agricultural skills helped farmers become more knowledgeable, which enhanced the results of food security. These results demonstrate how knowledge acts as a mediator in converting training and services into noticeable increases in livelihoods. The study comes to the conclusion that two important ways to improve food security in the Gaza Strip are to invest in skill development and to boost agricultural services. To optimize the impact on household resilience and food security, policymakers and development practitioners are urged to create interventions that include technical assistance, input provision, and capacity-building initiatives.

Reviving an unpopular tourism destination through the placemaking approach: Case study of Ngawen temple, Indonesia

Description:

Changes in tourists’ behavior in recent times have been considered a driving force for emphasizing the importance of unpopular tourism destinations as one of the key potentials in the tourism industry in any nation. On the road to reviving unpopular tourism destinations, this study aims to identify the potential tourism aspect and development of the Ngawen Temple in Indonesia. This research applies the placemaking approach as the main strategy for resurrecting Ngawen Temple. By using visitor surveys, visitor flows, and community surveys, this research obtains a clearer assessment for determining the planning development of Ngawen Temple. The research results revealed that unpopular destinations still have the potential to be developed and bring more benefits to the local economy by conducting a comprehensive placemaking approach. Accordingly, possible strategies based on various literature and field observations can provide clues to stakeholders on how to use their tourism assets to improve local communities’ economies. Some of the most frequently proposed strategies are the following: link the unpopular destination with other popular ones through structured tourism trips; design a “tourist trap,” which is a created place to hold tourists longer in a destination using new additional facilities; improve the infrastructure; and establish more creative tourism spaces, such as tourism centers.

Counterhegemony: Radical Economics and the Appeal of State Socialism in Cold War Era Nigeria (1946–1990)

Adam Mayer

Publication Name: International Journal of African Historical Studies

Publication Date: 2021-01-01

Volume: 54

Issue: 3

Page Range: 377-397

Description:

Normative state socialist economic theory appeared in the mid-1920s with Soviet economist Preobrazhensky. In Nigeria, many economic thinkers were influenced by Soviet and other Eastern European economic theory during the Cold War years. Bala Usman and Segun Osoba focused on the destruction of feudal land law and on delinking from the capitalist world economy; Bade Onimode and Ola Oni on emulating state socialist Eastern European economic theory and practice in an effort to overcome structural underdevelopment; Claude Ake in his Marxist phase made use of the Hungarian economist Tamás Szentes’s heterodox socialist development theory that the latter developed while the two were colleagues at the University of Dar-es-Salaam in Tanzania. Nigeria’s oil incomes were to be used in all these plans to kick-start heavy industry in the country. As the USSR’s alternative globalization path disappeared and then the Nigerian compradores’ share of profits grew by the early 21st century, interest in these radical classics reappeared in Nigeria.

Description:

The purpose of a Multiphysics Analysis is the modeling of complex physical systems where different kinds of physical effects act simultaneously. We would like to predict the behavior of a machine with the least number of neglected effects. Nowadays more Finite Element Method (FEM) based simulation software are readily available to study the physics of an electrical machine. Although, there are no standardized solutions that would fit every kind of electric motor analysis. In this paper we will present a method how to go through step-by-step on the different physical phenomena of an electrical machine and therefore analyze the different design and working aspects.

Type-2 Neutrosophic Markov Chain Model for Subject-Independent Sign Language Recognition: A New Uncertainty–Aware Soft Sensor Paradigm

Áron Ballagi Oday Ali Hassen Saad M. Saad Muslem Al-Saidi

Publication Name: Sensors

Publication Date: 2024-12-01

Volume: 24

Issue: 23

Page Range: Unknown

Description:

Uncertainty-aware soft sensors in sign language recognition (SLR) integrate methods to quantify and manage the uncertainty in their predictions. This is particularly crucial in SLR due to the variability in sign language gestures and differences in individual signing styles. Managing uncertainty allows the system to handle variations in signing styles, lighting conditions, and occlusions more effectively. While current techniques for handling uncertainty in SLR systems offer significant benefits in terms of improved accuracy and robustness, they also come with notable disadvantages. High computational complexity, data dependency, scalability issues, sensor and environmental limitations, and real-time constraints all pose significant hurdles. The aim of the work is to develop and evaluate a Type-2 Neutrosophic Hidden Markov Model (HMM) for SLR that leverages the advanced uncertainty handling capabilities of Type-2 neutrosophic sets. In the suggested soft sensor model, the Foot of Uncertainty (FOU) allows Type-2 Neutrosophic HMMs to represent uncertainty as intervals, capturing the range of possible values for truth, falsity, and indeterminacy. This is especially useful in SLR, where gestures can be ambiguous or imprecise. This enhances the model’s ability to manage complex uncertainties in sign language gestures and mitigate issues related to model drift. The FOU provides a measure of confidence for each recognition result by indicating the range of uncertainty. By effectively addressing uncertainty and enhancing subject independence, the model can be integrated into real-life applications, improving interactions, learning, and accessibility for the hearing-impaired. Examples such as assistive devices, educational tools, and customer service automation highlight its transformative potential. The experimental evaluation demonstrates the superiority of the Type-2 Neutrosophic HMM over the Type-1 Neutrosophic HMM in terms of accuracy for SLR. Specifically, the Type-2 Neutrosophic HMM consistently outperforms its Type-1 counterpart across various test scenarios, achieving an average accuracy improvement of 10%.

Intelligent wavelet based pre-filtering method for ultrasonic sensor fusion inverse algorithm performance optimization

György Kovács Szilvia Nagy

Publication Name: Inventions

Publication Date: 2021-06-01

Volume: 6

Issue: 2

Page Range: Unknown

Description:

Certain obstacle mapping applications require the live evaluation of the measured data to prevent collision with obstacles. The fusion of different or similar sensors usually has a high calculation demand, which increases significantly with the area to be evaluated and the number of sensors. In the present considerations, we propose a wavelet-based adaptive optimization method, which can greatly decrease the number of grid points to be evaluated, and thus the necessary computation time. The basis of the method is to use the fact that the areas to be evaluated mostly face a rather small number of obstacles, which cover a smaller percentage of the whole environment. The first step in a pre-filtering process is the determination of the zones where no obstacles are present. This step can already result in a considerable decrease in the computation time, however with the transformation to polar coordinates, the method will not only be more fitted to the problem to be solved, but the area of the evaluation can also be increased with the same number of grid points. As a last step, we applied wavelet transformation to identify the regions of interest, where the application of a refined raster is necessary, and thus further decreasing the number of grid points where the calculation has to be carried out. We used our previously developed probability-based ultrasonic sensor fusion inverse algorithm to demonstrate the efficiency of the proposed method.
