Description:

In vehicles there are 3 main noise sources: powertrain noise (e.g. engine, gear engagement or exhaust noise), aerodynamic noise (or wind noise), and the noise from the tire-road contact. The first two are traditionally in the primary focus of vehicle manufacturers, however, due to both the already made powerful developments and the spreading of electric vehicles, the rolling noise is gaining more and more attention during the vehicle development process. There are two major influencing factors of this noise source: tire (geometrical and material) characteristics and road (surface) characteristics. The separation of their contribution is not straightforward, investigated rarely, and the requirements of homologation standards do not expect it neither. However, if one would like to meet the new vehicle pass-by noise regulations, it is more and more inevitable to have a sophisticated break-down of rolling noise. A straightforward solution is the usage of a one-wheel testbench developed directly for acoustical measurements. Such design process is presented in this paper, where the most important requirements are: enabling the users to compare tires from acoustical aspect under totally objective conditions, modelling the typical conditions of vehicles and ensuring data for rolling noise simulations. One further functionality of the testbench is to reproduce the real rolling noise by mounting realistic road surface sections onto the superficies.

Publication Name: Industria Textila

Publication Date: 2024-01-01

Volume: 75

Issue: 4

Page Range: 396-404

Description:

This study aims to determine the impact of supply chain integration on supply chain performance and the Internet of Things (IoT) mediating role in Sindh Pakistan's textile industry. Primary data was gathered with the help of questionnaires from previous studies. The employees were requested to complete the questionnaire online, and the concerned HR department was officially contacted. To achieve the research objectives of this study, SmartPLS version 3 is applied. The findings of this study confirmed the direct effect of internal integration, supplier integration, and the Internet of Things on supply chain performance. In addition to this, the present study also confirmed the partial mediation effect of IoT between internal integration, supplier integration, and supply chain performance in the textile industry of Sindh, Pakistan, a developing country. This research uses RBV theory to examine the textile industry's supply chain and effectiveness. Internal integration, partner integration, IoT, and supply chain performance are discussed in the research. This clarifies how these technologies operate together to give organizations a competitive advantage. The study shows how the Internet of Things (IoT) is a go-between for integration and supply chain success. Textile business managers should consider investing money into IoT devices and using their benefits. Companies can get real-time information about their supply chain by using IoT devices and monitors.

Consumption patterns in urban sophisticate branding. A qualitative perspective on its psychological foundations

Ebtesam Abdullah Alzeiby Dhruv Galgotia Eszter Szabó-Szentgróti Nidhi Sahore

Publication Name: Acta Psychologica

Publication Date: 2026-02-01

Volume: 262

Issue: Unknown

Page Range: Unknown

Description:

The emergence of the urban sophisticate consumer has led to changing consumption patterns in the global retail landscape. While there has been a surge in academic literature examining various aspects of urban sophistication, empirical studies examining the attributes of the urban sophisticated consumer in the context of fashion apparel, fashion accessories, and grooming products still need to be included. This study investigates the concept of ‘urban sophisticate’ consumers in the context of marketing, branding, and retailing for the first time. It has proposed a conceptual framework for retailing to urban sophisticates through a qualitative inductive method based on the empirical analysis of the open essay-based responses collected from working men in the UK. The factors making this consumer segment lucrative for retailers include high spending power, focus on appearance, desire for quality, and the availability of unique products as per their preferences. Urban sophisticate consumers prefer modern, high-end fashion items and have shown displeasure towards unsustainable fast fashion. The study's findings will benefit grooming product companies, fashion apparel and accessories marketers, and retailers by providing insights into the behaviour of urban sophisticate consumers. Furthermore, this study could be a turning point to elicit marketers' experimentation in designing new products and expanding their product base to include additional product offerings that could interest urban sophisticates.

Assessing and evaluating potential systems resilience

Péter Földesi Eszter Sós Borbála Tamás

Description:

The hierarchy of semantic networks can also be observed in the functioning of economic systems. There are uncertainties in semantic networks, meaning that the classification of different attributes is not always clear. The same uncertainty is also present, for example, in the design of logistics strategies as a sub-strategy of the economy, which can lead to inconsistencies between the parameters of the system. It is important for a system to be resilient to both internal and external influences, and it is, therefore, necessary to develop a hierarchy of system parameters based on the semantic network's method and to examine the relationship between parameters in order to achieve resilience and long-term sustainability.

Description:

During car services, it is sometimes necessary to measure the effective performance of the engines. After repairs it is very useful to check the change of the performance. In this case you don't have possibility of dismantling. You can measure the vehicle on roll benches. In this case you have so-called wheel performance as result. The new method discussed and described in this article provides a solution to this problem. The paper contains the theoretical and practical introduction of the measurement of engine performance with diagnostic measurement processes.

Analysis Of The Dynamics Of Cashless Payments In Kazakhstan In The Context Of The Covid-19 Pandemic

Laszlo Vasa Anna Kredina Aigul Akparova

Publication Name: Economy Strategy and Practice

Publication Date: 2021-01-01

Volume: 16

Issue: 2

Page Range: 54-61

Description:

The COVID-19 pandemic has accelerated the development of FinTech and the transition to cashless payments of the population of various countries, including Kazakhstan. For provision of cashless payments there are created platforms which work in NFC & MFS systems, they protected by security protocols (Secure Element (SE)) and allow to store confidential user data. Changes in the business model of banks have led to the emergence of a new format of banking products and services that can be used through smartphones (the main operating systems Android and iOS). The goal of the study is to analyze the dynamics of the impact of the COVID-19 pandemic on the use of cashless payments through national payment systems in Kazakhstan. Based on the goal, a null and an alternative hypothesis were set, of which the second was confirmed in the result. Research methods used to write this article are economic and statistical analysis and synthesis, graphical method, analysis of the series of dynamics. The data for the study was taken from the NBK Statistical Bulletin: data on cashless payments through the Interbank System of Money Transfer (ISMT) and the Interbank Clearing System (ICS) for the period from 2002 to 2020. The impact of the COVID-19 pandemic on the dynamics of the transformation of cashless payments made by using financial technologies has been proved. Recommendations for further improvement of the financial system are given. The development of national payment systems makes it possible to reduce the level of fraud in the financial sector, to increase the speed of cashless transfers and level out transaction errors. Study limitation: only national payment systems ISMT and ICS were used.

Fuzzy logic-supported student task generation - The future of AI-based testing in school practice

Eniko Nagy Karl Eva Gyorgy Molnar

Publication Name: Cando EPE 2026 IEEE 8th International Conference and Workshop in Obuda on Electrical and Power Engineering Proceedings

Publication Date: 2026-01-01

Volume: Unknown

Issue: Unknown

Page Range: 137-142

Description:

In school practice, one obstacle to the spread of computer-based, AI-supported testing is that most tasks still originate with teachers, making task bank maintenance time-consuming. In our previous work, we showed that student-generated questions can be incorporated into the assessment process when teacher experience and student performance data are handled through a fuzzy-based method integrated into the WTCAI (When The Child Asks with AI) school decision support system. This study extends that framework by addressing a specific problem: the difficulty label assigned by the teacher at the time of task creation may become inaccurate as successive cohorts with different profiles solve the same item. We present a fuzzy rule-based dynamic update mechanism that recalibrates task difficulty based on observed class-level performance, without overriding teacher judgment. Drawing on a previously established school dataset and school-based observational data [18], we explore this problem and present a practical, teacher-interpretable algorithmic solution. The paper, therefore, presents a practical and interpretable recalibration framework, with empirical validation currently underway.

Description:

The objective of this paper is to provide a thorough examination of the developmental trajectory of female entrepreneurship research in order to address the lacuna in the literature. The study employs a combination of co-word analysis and main path analysis (MPA) to conduct a systematic review of the citation network of female entrepreneurship research. This methodology facilitates the identification of dominant themes and foundational works, thereby mapping the gradual diffusion of knowledge throughout the field. The results indicate that critical themes, including the role of social networks in empowering female entrepreneurs, gender biases, access to finance, and entrepreneurial motivation, are present. The MPA delineates the manner in which early works concentrated on gendered challenges, while more recent research has explored topics such as innovation, work-life balance, and microfinance in developing economies. Furthermore, the study underscores emerging trends, including the influence of digitalization and institutional barriers on entrepreneurship. This study is the first to integrate co-word analysis with MPA in the context of female entrepreneurship, thereby offering a comprehensive and innovative perspective on the field’s evolution. In doing so, it provides valuable insights into the evolving research landscape, emphasizing critical gaps and suggesting promising areas for future investigation. This method establishes a precedent for the implementation of more data-driven reviews in the field of entrepreneurship research.
