Abstract
Purpose
This paper aims to study the lubrication and sealing performance on the textured piston pair under the cross action of the shape and structure parameters. This paper further carries out the optimization design of low energy consumption hydraulic impact piston pair.
Design/methodology/approach
Based on the characteristics of the ring gap seal piston pair, the flow field analysis model of the whole film gap is established for its periodic treatment. The friction power loss of the piston pair is defined as the evaluation index of the lubrication performance and the leakage power loss as the evaluation index of the sealing performance. The orthogonal test design and CFD software were used to analyze the lubrication and sealing performance of the textured piston pair.
Findings
The cross action of shape and structure factors has a great influence of the lubrication and sealing performance on the textured piston pair. Clearance and shape parameters have great influence on it, while seal length and depth diameter ratio have little influence. The sealing performance of conical textured piston pair is good, while the lubrication performance of square textured piston pair is good. The primary and secondary order of influence of shape and structure on energy consumption on piston pair is B (seal clearance) > C (texture shape) > D (area ratio) > A (seal length) > E (depth diameter ratio).
Originality/value
Breaking the defect of local optimization design on traditional piston pair structure, then find the matching relationship of structural parameters on textured piston pair. Further improve the lubrication and sealing performance of the piston pair, and provide reference for the global optimization design of the low energy consumption hydraulic impact piston pair.

Abstract
Purpose
To solve problems of low intelligence and poor robustness of traditional navigation systems, the purpose of this paper is to propose a brain-inspired localization method of the unmanned aerial vehicle (UAV).
Design/methodology/approach
First, the yaw angle of the UAV is obtained by modeling head direction cells with one-dimension continuous attractor neural network (1 D-CANN) and then inputs into 3D grid cells. After that, the motion information of the UAV is encoded as the firing of 3 D grid cells using 3 D-CANN. Finally, the current position of the UAV can be decoded from the neuron firing through the period-adic method.
Findings
Simulation results suggest that continuous yaw and position information can be generated from the conjunctive model of head direction cells and grid cells.
Originality/value
The proposed period-adic cell decoding method can provide a UAV with the 3 D position, which is more intelligent and robust than traditional navigation methods.

Abstract
Purpose
Due to white rice’s association with diabetes and other chronic diseases in many Asian countries, many industries are working to develop high-fiber rice substitutes with similar organoleptic characteristics. Konjac rice (KR) is a promising option, but maintaining its optimal fiber content for health benefits while preserving its ideal sensory profile remains a challenge. This study aims to investigate whether a KR formula, combining tapioca flour and glucomannan gel, possesses similar organoleptic attributes to white rice while preventing glycemic response elevation.
Design/methodology/approach
In a six-week randomized single-blind clinical trial, 13 normoweight nondiabetic subjects received varying konjac-based rice and white rice ratios. Blood glucose levels were measured at intervals, and glycemic response was assessed using incremental area under the curve (iAUC). Visual analog scale gauged satiety, and organoleptic properties were evaluated.
Findings
Substituting white rice with pure and partial konjac-based rice significantly lowered postprandial blood sugar levels and glycemic response (p = 0.002). iAUC for pure KR and KR 1:1 was notably lower than white rice (p = 0.002). Subjects reported a sense of fullness comparable to white rice, with no significant organoleptic score differences (p = 0.260).
Research limitations/implications
The study’s generalizability is compromised due to the limited number of participants, impacting external validity. The examined parameters offer a rough understanding of konjac grain’s impact on postprandial glycemic responses but do not elucidate underlying mechanisms or the duration of its inhibitory effect on glucose absorption. Long-term effects on metabolic, hormonal parameters and the colon’s microbial flora composition and function remain unexplored, constraining comprehensive insights into konjac grain’s extended implications.
Practical implications
This study introduces a novel KR formula to address the escalating diabetes risks associated with white rice consumption. Substituting white rice with KR significantly reduces postprandial blood sugar levels, highlighting its potential in preventing type 2 diabetes (T2D). Tapioca flour enhances palatability, making KR a viable option. While promising, long-term effectiveness and safety require further research, emphasizing comprehensive lifestyle interventions. The study contributes valuable insights to innovative dietary strategies for prevalent health conditions, emphasizing the need for ongoing efforts in public health.
Social implications
White rice, a staple in Asian societies, is linked to a heightened risk of T2D due to increased production and inadequate dietary fiber. This connection contributes to the economic burden on governments through health insurance and lost productivity. Encouraging alternatives rich in fiber can mitigate this burden, offering a socioeconomically beneficial solution to preventable chronic diseases.
Originality/value
This trial demonstrates konjac-based rice’s potential in curbing glycemic responses, hinting at its role in preventing T2D. Glucomannan’s viscosity, satiety induction and potential gut health impact are highlighted. Further research is warranted for long-term effectiveness and safety. These findings contribute to the growing evidence supporting glucomannan as a valuable tool in addressing prevalent health conditions.

Abstract
Purpose
The purpose of this study is to investigate the impact of Halal traceability technology usage on Halal logistics performance with a Halal logistics brand as a mediator.
Design/methodology/approach
An online survey was conducted to gather responses from logistics service providers (LSPs), including strategic logistics units (manufacturing/brand owners) in Malaysia, which offer Halal logistics services.
Findings
Halal traceability technology system and Halal traceability training are two critical domains to strengthen market recognition of Halal logistics brand for LSPs. The study found that the Halal logistics brand played a mediating role in connecting the usage of Halal traceability technology and logistics performance.
Practical implications
The logistics industry needs to focus on Halal logistics services as a unique proposition. The ability of LSPs to build a Halal logistics brand thru traceability technology had created positive impressions for clients. LSPs must consistently engage in Halal training and remain technologically alert to build Halal brand value. Halal-based strategic branding will assist an LSP to stand out among its competitors.
Originality/value
Even though Halal branding has been studied widely, little attention has been given to how the usage of Halal traceability technology can improve Halal logistics branding and logistics operational performance. The result suggests that LSPs need to build a Halal logistics brand and design a proper logistics business strategy to target Sharia compliance-oriented consumers.

Abstract
Purpose
This paper aims to investigate how manufacturing firms behave to mitigate business risk during and post-COVID-19 coronavirus disease (COVID-19) on the global supply chain.
Design/methodology/approach
A systematic literature review for data mining was used to address the research objective. Multiple scientometric techniques (e.g. bibliometric, machine learning and social network analysis) were used to analyse the Lens.org, Web of Science and Scopus databases’ global supply chain risk mitigation data.
Findings
The findings show that the firms’ manufacturing supply chains used digitalisation technologies such as Blockchain, artificial intelligence (AI), 3D printing and machine learning to mitigate COVID-19. On the other hand, food security, government incentives and policies, health-care systems, energy and the circular economy require more research in the global supply chain.
Practical implications
Global supply chain managers were advised to use digitalisation technology to mitigate current and upcoming disruptions. The manufacturing supply chain has high uncertainty and unpredictable global pandemics. Manufacturing firms should consider adopting Blockchain technology, AI and machine learning to mitigate the epidemic risk and disruption.
Originality/value
This study found the publication trend of how manufacturing firms behave to mitigate the global supply chain disruptions during the global pandemic and business uncertainty. The findings have contributed to the supply chain risk mitigation literature and the solution framework.

Abstract
Purpose
The purpose of this paper is to analyze the effect of internal control on tax avoidance analyzing internal (family ownership) and external (environmental uncertainty) factors on the effectiveness of internal control in preventing tax avoidance.
Design/methodology/approach
First, the authors examine the direct effect of the effectiveness of internal control on tax avoidance. Second, the authors examine the effect of moderation of family ownership and environmental uncertainty on the relationship of the effectiveness of internal control on tax avoidance. Third, the authors divide the full sample into two groups, high and less effectiveness of internal control to examine the direct effect of internal control effectiveness on tax avoidance and when considering moderating variables. Fourth, the authors use two different measures of the effectiveness of internal control.
Findings
This research found that effective internal control can reduce tax avoidance. Family ownership affects the relationship between internal control and tax avoidance, but environmental uncertainty does not influence the relationship between internal control and tax avoidance.
Practical implications
Internal control increases compliance with rules and policies, so companies must design and implement effective internal control to prevent tax avoidance activities in violation of tax regulations.
Originality/value
In contrast to previous studies, this study measures the effectiveness of internal control using the index of internal control practice disclosure and considers internal and external factors that can affect the effectiveness of internal control to prevent tax avoidance.

Abstract
Purpose
This paper aims to review how the metaverse influences and contributes to the halal industry, particularly focusing on halal logistics (HL), halal supply chain management (HSCM) and consumer behavior.
Design/methodology/approach
This paper analyzed scholarly studies to investigate existing literature and current as well as future trends in the adoption of the metaverse in HL, supply chains and consumer behavior. The study explores the thematic structure of the current knowledge landscape, identifies research gaps and highlights potential directions for future research at the intersection of the metaverse, supply chain and halal behavior. The authors identified 286 papers that examined the integration of the metaverse with HL practices, supply chain management strategies and consumer behavior in alignment with Islamic principles and standards.
Findings
The results indicate a limited number of studies on the successful adoption of the metaverse in HL, HSCM and behavioral research. This paper has proposed a framework for the metaverse-supply chain and halal behavior. The framework can serve as a reference for scholars and practitioners on how to incorporate advanced technology to engage with and predict market demand. Additionally, the metaverse-supply chain framework can be used to align with halal supply chain practices based on customer needs and preferences. The metaverse integrates the virtual world, enabling halal supply chain networks to enhance virtual reality, digital experiences and business performance.
Practical implications
The halal industry can showcase products and services through virtual scenarios, avatars and shops. By developing a halal-compliant metaverse, the halal industry can facilitate activities such as online sales, online payments and virtual marketing, thereby enabling a digital business transformation. Embracing the metaverse can improve business efficiency and influence consumer behavior, decisions and compliance with Shariah principles.
Originality/value
The authors argue that this paper is at the forefront and will serve as a reference for future research. This paper is distinct from existing literature, as it focuses on metaverse adoption and its correlation with a Shariah compliance framework in logistics, supply chain and behavioral aspects. Through its findings, this framework aims to inspire further empirical research and provide guidance and solutions to foster sustainable development in the halal industry.

Abstract
Purpose
This paper aims to model Muslim consumers' purchase behaviour that predicts the impacts of behavioural factors of spirituality, emotional value, image, trust and satisfaction on Halal-labelled food products. The model was used among Muslim consumers in Indonesia and France.
Design/methodology/approach
A survey was conducted among Indonesian and French Muslim consumers who had bought Halal-labelled food products. The model was examined using Partial Least Squares Structural Equation Modeling (PLS-SEM) with multi-group analysis (PLS-MGA) to test specific differences between sample groups.
Findings
All proposed hypotheses were accepted, except for the trust in purchasing behaviour. It was not significantly different in the two sample groups. The linkage from image to purchasing behaviour was not significantly related to the French sample group, and emotional value did not influence Halal-labelled food product purchase behaviour in the Indonesian sample group. The MGA results found a significant difference in spirituality, emotional value image and trust among Indonesian and French Muslim consumers.
Practical implications
The guarantee of Halal food through a Halal label can fulfil the spirituality of Muslim consumers in carrying out Allah’s (SWT) command to consume Halal food, creating a product image, trust, satisfaction and emotional value that encourages positive buying behaviour. The finding shows that Muslim spirituality has extended the Islamic marketing literature to predict Muslim consumer behaviour. The company can emphasise in advertisements that the Halal-certified logo reflects the quality of products.
Originality/value
To the best of the authors’ knowledge, this research is among the early study empirically confirming that spirituality and emotional value are critical domains to predict purchase behaviour between two different groups of Indonesian and French Muslim consumers.
