Virtual Teamwork in Gamified 3D Environment
Publication Name: Infocommunications Journal
Publication Date: 2023-01-01
Volume: 2023
Issue: Unknown
Page Range: 15-20
Description:
Virtual teamwork has spread strongly in various fields in recent times. COVID lockdown measures radically boosted the use of distance-independent remote collaboration methods. Although there are many modern virtual 3D spaces available for teamwork today, they lack additional motivational factors other than the visual 3d experience. Based on this, we tried to research the possible benefits of using gamification technics in 3D virtual collaboration environments to increase virtual team members' motivation. This article attempts to explore and highlight the possibilities of this area, and propose a model framework for implementation of gamified elements in 3D virtual teamwork environments.

Futuristic advancements in phytoremediation of endocrine disruptor Bisphenol A: A step towards sustainable pollutant degradation for rehabilitated environment
Publication Name: Waste Management
Publication Date: 2024-04-30
Volume: 179
Issue: Unknown
Page Range: 216-233
Description:
Bisphenol A (BPA) accumulates in the environment at lethal concentrations because of its high production rate and utilization. BPA, originating from industrial effluent, plastic production, and consumer products, poses serious risks to both the environment and human health. The widespread aggregation of BPA leads to endocrine disruption, reactive oxygen species-mediated DNA damage, epigenetic modifications and carcinogenicity, which can disturb the normal homeostasis of the body. The living being in a population is subjected to BPA exposure via air, water and food. Globally, urinary analysis reports have shown higher BPA concentrations in all age groups, with children being particularly susceptible due to its occurrence in items such as milk bottles. The conventional methods are costly with a low removal rate. Since there is no proper eco-friendly and cost-effective degradation of BPA reported so far. The phytoremediation, green-biotechnology based method which is a cost-effective and renewable resource can be used to sequestrate BPA. Phytoremediation is observed in numerous plant species with different mechanisms to remove harmful contaminants. Plants normally undergo several improvements in genetic and molecular levels to withstand stress and lower levels of toxicants. But such natural adaptation requires more time and also higher concentration of contaminants may disrupt the normal growth, survival and yield of the plants. Therefore, natural or synthetic amendments and genetic modifications can improve the xenobiotics removal rate by the plants. Also, constructed wetlands technique utilizes the plant's phytoremediation mechanisms to remove industrial effluents and medical residues. In this review, we have discussed the limitations and futuristic advancement strategies for degrading BPA using phytoremediation-associated mechanisms.

A novel hybrid neutrosophic-fuzzy-uncertain data envelopment analysis model for assessment of wind farm locations
Publication Name: Energy Nexus
Publication Date: 2026-06-01
Volume: 22
Issue: Unknown
Page Range: Unknown
Description:
Renewable energy resources have got much attention in recent years. Because of climate change in the world, the countries try to develop renewable energy resources. Wind farms are renewable energy resources that can produce electricity with no negative effect on climate change. In this study, as an important topic, the location selection problem of wind farms is considered as a real case study. For the first time, a multi-criteria wind farm location selection problem with neutrosophic fuzzy and uncertain criteria at the same time is developed. As the set of criteria consists of both input and output criteria, we develop a novel hybrid neutrosophic-fuzzy-uncertain scheme of BCC DEA model for the first time to solve the problem. As solution approach, a chance-constrained programming approach based on possibility measure of the neutrosophic fuzzy constraints of the model also for the first time is proposed in this study. An extensive computational study on the case study by the proposed approach is performed. The candidate locations of the case study are prioritized where the location of Birjand city with score of 1.1656 is selected as the best location. A sensitivity analysis on the confidence levels of the chance-constrained programming approach is performed and also the obtained results are compared to the approaches of the literature.

The effect of mint addition on the physicochemical and organoleptic properties of strawberry sorbets
Publication Name: Food Chemistry X
Publication Date: 2025-02-01
Volume: 26
Issue: Unknown
Page Range: Unknown
Description:
The study aimed to produce, analyse, and evaluate the consumer acceptance of a functional peppermint-, and spearmint-enriched (0.5,1,2 %) sorbet, which contains only natural substances in its composition, to meet today's popular health-conscious consumer trends. Regarding acid composition, the sorbets contained malic acid, succinic acid, and citric acid. Sorbets regarded of water-soluble sugars, contained sucrose in the lowest concentration, followed by glucose, and the amount of fructose, which is typical for fruits, was the highest. The sorbets' TPC and TAC contents were determined to be between 510.72 and 743.77 mg GAE/kg, and 906.64 and 1137.67 mg AAE/kg respectively. The average melting rate of the desserts was 0.16–0.22 g/min, and based on consumer acceptance, the control and the samples added with 0.5 % spearmint and peppermint mint were the most favorable. The sorbets containing 1 % and 2 % mint had too intense menthol flavor, thus the enjoyment value of the products was reduced based on consumer feedback.

Performance analysis of a robust design optimization of a solenoid with different sensitivity metrics
Publication Name: Journal of Computational and Applied Mathematics
Publication Date: 2023-05-01
Volume: 424
Issue: Unknown
Page Range: Unknown
Description:
Optimization is an essential part of designing electrical machines and devices. Considering the uncertainties and tolerances from the beginning of the design process can lead to a more robust design and significantly reduce the number of waste products during the manufacturing process. However, the computational demand for these robust design optimization problems is amazingly high. This paper examines how the computational demand and the robustness of the results depend on the applied sensitivity metric. The multi-objective TEAM 35 benchmark problem has been used as the basis of the comparison. This optimization task aims to create a homogeneous magnetic field in a predefined coil region, which is insensitive to the positioning errors of the coil turns. The original definition of the problem uses a simple worst-case sensitivity metric calculated from the extreme values of the optimized turn parameters in the given tolerance range. This sensitivity metric has been replaced by Plackett–Burman, Box–Behnken, and Central Composite Design-based metrics. It was shown in this simple geometry that there is a significant difference between the resulting sensitivities. Nevertheless, Plackett–Burman and Central Composite Design provided the more accurate and consistent estimate of the sensitivity of the examined layouts, with a higher but still reasonable computation demand than the worst-case metric.

Exploring Internal Factors Of Capacity Expansion Decision-Making In Hungarian Family Businesses In Food Industry: Introducing A Novel Model
Publication Name: Journal of Cultural Analysis and Social Change
Publication Date: 2025-11-25
Volume: 10
Issue: 2
Page Range: 3325-3342
Description:
The purpose of the research on which this paper is based was to test and validate the decision-making model previously set up by the authors. The model presents the internal factors influencing the decisions of family businesses regarding capacity expansion and the possible decision outcomes. The distinctiveness of the model is that it presents the internal factors affecting decisions related to capacity expansion, thereby helping family businesses to make decisions. For collecting data, both qualitative and quantitative techniques were used. As qualitative data collection techniques, in-depth interviews and focus group interviews were conducted. As quantitative method, an online questionnaire was used, whose questions were compiled based on previous research of the authors. The questions indirectly assess the internal factors influencing capacity expansion decisions of family businesses and the possible outcome of the decisions. The questionnaire was sent to the VOSZ (National Association of Entrepreneurs), MAPI (Hungarians on the Market Club) and the Association of Family Entrepreneurs, which means approximately 500 addresses. After data cleaning, 135 completed questionnaire were analyzed with SPSS software. In-depth interview was conducted with the heads of five family businesses, whose results were analyzed using tagging and artificial intelligence. The model previously set up by the authors was validated by both qualitative and quantitative research. It can be concluded that the following three internal factors influence the decision of family businesses regarding capacity expansion: socio-emotional wealth, cooperation between generations, and heterogeneous top management team. The family businesses themselves are not necessarily aware of this, so the model enriches the scientific literature and helps in the conscious operation of family businesses.

Robustness of a flux-intensifying permanent magnet-assisted synchronous reluctance machine focusing on shifted surface-inset ferrite magnets
Publication Name: Computers and Structures
Publication Date: 2025-09-01
Volume: 316
Issue: Unknown
Page Range: Unknown
Description:
Flux-intensifying permanent magnet-assisted synchronous reluctance machines use relatively small amounts of non-rare earth permanent magnets, making them viable alternatives for remanufacturing older machines, aligning with EU directives and circular economy principles. The asymmetric rotor topology is particularly suited for micromobility applications, which benefit from shifting inset magnets, as reverse motoring is rarely required. However, this design could be more sensitive to manufacturing and positioning errors of the magnets. To investigate the effects of the uncertainties of the shifted surface inset magnets, first, an optimal topology is selected based on average torque, torque ripple, and cogging torque using the NSGA-II optimisation method. The effects of the magnet shifting and its robustness are analysed using the Taguchi and ANOVA methods, validated by Full Factorial calculations. Results indicate a 31.25 % reduction in permanent magnet volume without compromising torque output with magnet shifting. The machine's average and cogging torque remain within a 5 % robustness threshold for a ±0.06 mm discrete manufacturing tolerance. Torque ripple may exceed this limit up to 14.77 %. However, the likelihood of exceeding the threshold is only 12.10 %. The reduced magnet volume and maintained performance make this topology a promising option for remanufactured machines in micromobility applications, supporting circular economy goals.

Mapping IT and Management Challenges in Small and Micro-Businesses: A Path to Digital Maturity in Manufacturing †
Publication Name: Engineering Proceedings
Publication Date: 2024-01-01
Volume: 79
Issue: 1
Page Range: Unknown
Description:
Small and micro-businesses often struggle with poor data accuracy due to a lack of dedicated labor force for non-core business functions. The required efforts and costs associated with improving data accuracy, such as setting up and operating an adequate inventory management system, are unpredictable for these businesses. Despite the data-intensive nature of operating specialized software like MES and WMS, the decision to invest in excessive data manipulation can be challenging for micro-entities, even with the potential benefits. This study aims to empirically determine the challenges, risks, and other non-financial decision factors micro-enterprises face when establishing effective data management and utilization practices. A data model was developed based on interviews with 17 small business manufacturers and service companies to support the essential data entry requirements of micro-businesses. The findings support the concept of a SAAS (Software as a Service) product tailored to the needs of these businesses. Furthermore, this research highlights the under-researched areas of logistics processes and data management in small businesses.
