A Hybrid LOPCOW–PROMETHEE framework under linear Diophantine fuzzy sets for sustainable planning

Dragan Pamucar S. Rajareega Jeevitha Kannan Vimala Jayakumar

Publication Name: International Journal of Optimization and Control Theories and Applications

Publication Date: 2026-01-13

Volume: 16

Issue: 1

Page Range: 321-348

Description:

Imprecision, uncertainty, and conflicting criteria often complicate the process of identifying the optimal conclusions in real-world decision-making scenarios. This paper suggests a novel multi-criteria decision-making (MCDM) framework that combines a hybrid logarithmic precursor chain-driven objective weighting–preference ranking organization method for enrichment of evaluations technique with linear Diophantine fuzzy sets to address uncertain frameworks. The selection of the location of a Sustainable Emergency Service Station and the selection of an investment portfolio are two real-world and socially significant decision-making challenges where traditional MCDM approaches fail to address the uncertainties. Our suggested fuzzy-based paradigm demonstrates the adaptability of both infrastructure design and financial decision-making. The results provide the optimal solutions based on our requirements, even under unpredictable conditions. The outcomes of sensitivity analysis and comparative analysis demonstrate how well the suggested approach handles ambiguous and imprecise data, particularly when expert opinions are presented in a linguistically or incompletely articulated manner. This work provides a solid, scalable, and precise method for resolving MCDM issues in the face of ambiguity, offering improved support to decision-makers in a range of fields.

Measurement and analysis of vibration levels in stacked small package shipments in delivery vans as a function of free movement space

Péter Böröcz Bence Molnar

Publication Name: Applied Sciences Switzerland

Publication Date: 2020-11-01

Volume: 10

Issue: 21

Page Range: 1-13

Description:

In recent years there has been a very significant increase in parcel delivery shipments all over the world. Moreover, this mode of delivery, in some cases, is facing a very intensive flow of goods, such as in annual festive seasons or, for instance, in situations like COVID-19 when personal purchase of goods is strictly limited in malls. This often means that delivery vehicles operate at almost full capacity, and many same or different kinds of packages are therefore stacked in small delivery vehicles. In this study, we measured and analyzed the vibration levels that occur in smaller stacks of packages in parcel delivery shipments, paying particular attention to those circumstances such as stacking layers and free movement spaces that can affect the vibration in different layers of packages. The goal of this paper was to provide information about the vibration levels that occur in smaller stacks of packages that are not unitized and fixed, as is common in parcel transportation. The recorded vibration events were analyzed in terms of power spectral densities (PSDs) and supplied with statistical data of acceleration events to provide an understanding of the variability of intensity. Based on the results of this study, PSD spectra were developed for various free movement conditions, as well as spectra for each layer in the stacked parcel package shipment. The results showed that the vibration level increases in the stacked load upwards and with an increase of free space of possible movement. The results of this study can be used to simulate the measured vibration conditions in laboratory tests conducted on courier express parcel shipments.

At the Borderline of Public and Private Law: The Restitution of Cultural Property Held in Public Collections in Hungary

Vanda Vadász Viktória Verebélyi

Publication Name: Santander Art and Culture Law Review

Publication Date: 2024-01-01

Volume: 2024

Issue: 2

Page Range: 181-208

Description:

During the Second World War, and thereafter until the end of the communist regime in 1989, a massive amount of private-ly owned works of art came into the possession of the Hungarian state. The ownership of the property thus collected was only par-tially clarified after the war. After the fall of communism, national-ized cultural property was subject to restitution laws, but restitution typically meant partial compensation. The aim of this article is to highlight the shortcomings that still characterize the restitution of cultural property held in public collections in Hungary. After summa-rizing the historical-legal situation pertaining to restitution measures in Central and Eastern Europe, we provide a comprehensive overview of the Hungarian legal environment in terms of restitution. The focus is on the restitution rules adopted in the 2010s that were intended to settle the possession of cultural property held in public collections. The roots of constitutional issues related to the regulation arise from and are reflected in the intermingling of private law and public law characteristics and guarantees. In the presentation of civil law disputes concerning the ownership rights of property held in public collections, we outline the characteristics of the Hungarian regula-tory framework regarding protected cultural property and the issues arising from their application. Finally, we provide an overview of the European Court of Human Rights’ jurisprudence on the protection of property rights and an assessment of Hungarian regulations before the Court. We claim that the lack of predictability and certainty of the latter authority’s proceedings may lead to human rights issues.

Business Incubation as a Catalyst: Examining the Impact of Entrepreneurial Education on Entrepreneurial Intention in Emerging Contexts

Hirwan Jasbir Bin Jaafar Mohammad Fakhrul Islam Md Asaduzzaman Muhammad Asyraf Bin Mohd Kassim

Publication Name: Ianna Journal of Interdisciplinary Studies

Publication Date: 2026-01-05

Volume: 8

Issue: 1

Page Range: 202-217

Description:

Background: Entrepreneurial education (EE) and institutional support mechanisms such as Business Incubation Programmes (BIPs) play critical roles in shaping entrepreneurial intentions among university students. However, in Bangladesh, the relationship between EE, BIPs, and Entrepreneurial Intention (EI) remains underexplored, particularly from the perspective of resource-based and behavioural theories. Objective: Grounded in the Theory of Planned Behaviour (TPB) and drawing on the Resource-Based View (RBV), this study examines the role of BIPs in amplifying the impact of EE on EI among business students in Bangladeshi universities. Methodology: The study employed a quantitative research design, utilising a structured questionnaire administered to 388 business students from four leading universities in Dhaka. Data were analysed using SmartPLS 4.1.0.9 and SPSS 27 to test the proposed model and hypotheses. Results: The findings reveal that EE and BIP have a positive and significant influence on EI. Moreover, BIP substantially moderates the relationship between EE and EI, indicating that incubation programmes strengthen the effect of educational inputs on students’ entrepreneurial intentions. Conclusion: Integrating entrepreneurial education with institutional support mechanisms such as incubation programmes fosters a stronger entrepreneurial mindset and intention among students. Unique contribution: This study enriches entrepreneurship literature by integrating TPB and RBV perspectives to explain how cognitive and resource-based factors jointly shape entrepreneurial intention in an emerging South Asian economy. It also provides practical implications for educators, policymakers, and ecosystem stakeholders seeking to address graduate unemployment through entrepreneurship development. Key Recommendation: Universities should integrate business incubation Programmes with entrepreneurship education to provide practical support and enhance students’ entrepreneurial readiness.

Pavement Sustainability Implications of Different Lateral Wander Modes for Autonomous Trucks

Csaba Koren Richárd Nagy Mohammad Fahad

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 631-636

Description:

Autonomous trucks can bring changes in transport infrastructure in terms of sustainability based on the type of lateral wander mode used. In this research, two lateral wander modes, a zero wander and a uniform wander mode, are analysed based on their applicability for sustainability in terms of CO2 emissions. Life cycle analysis has been performed for the analysis period of 30 y for the pavement section of 10 km, along with fatigue predictions. Results show that zero wander mode generates more emissions as a result of premature fatigue damage under channelized loading. The uniform wander mode yields 20 % fewer emissions. Moreover, the use of full-depth reclamation during the pavement's Life Cycle improves the CO2 emissions by 15 % when compared to traditional removal and reconstruction methods. Therefore, the uniform wander mode is favourable for the improvement of pavement sustainability in terms of CO2 emissions.

An expert system for the cost-optimal refurbishment of buildings

Árpád Csík

Publication Name: Advanced Materials Research

Publication Date: 2014-01-01

Volume: 899

Issue: Unknown

Page Range: 599-604

Description:

In the present paper we propose a solid theoretical framework for the automatic parametrization of the cost-optimal refurbishment of arbitrary buildings. The parameters describe the structural parts of the building that can be modified or replaced during the refurbishment process. The methodology also provides the cost-optimal refurbishment cost and the corresponding smallest possible total life-cycle operation cost constrained by the available technological and economical limitations. The theory is implemented into the EnergOpt expert system providing fast and accurate answers to costoptimization problems appearing in common practical applications. The system is built on firm mathematical foundations that is supported by state-of-the-art optimization algorithms capable of finding good optimums in a short amount of CPU time. The modular structure of the IT implementation facilitates effortless localization in different countries. The application of the system may considerably contribute to the decrease of the heating energy consumption and the corresponding environmental load of the building stock. The practical potential of the technology is demonstrated by the energetic analysis of an existing family house. © (2014) Trans Tech Publications, Switzerland.

Embedded System Simulation Using Renode †

Istvan Szalay Ferenc Péter Speiser Denes Fodor

Publication Name: Engineering Proceedings

Publication Date: 2024-01-01

Volume: 79

Issue: 1

Page Range: Unknown

Description:

In the automotive industry, the reduction of development costs is of key importance. The development of electrical hardware is an expensive, time-consuming process with a lot of development stages (e.g., prototyping, electrical testing, mechanical testing, lifecycle testing). There is a growing need to increase the cost-effectiveness of the development and testing phases of embedded software using virtualization. Using this method, less prototype manufacturing is necessary since the simulations allow for faster and more effective discovery of a large portion of possible faults without building a hardware prototype. Renode is an open source embedded system simulation framework that facilitates software-based testing. The main goal of this paper is to explore the usability of the framework for automotive applications.
