Abstract

Purpose

Leading error in line laser weld seam tracking significantly affects tracking accuracy. This paper aims to propose an accurate and reliable compensation method without increasing system complexity for weld seam tracking to improve tracking precision.

Design/methodology/approach

Based on the line laser seam tracking method, the seam image is simultaneously captured to obtain the angle offset of the seam relative to the sensor direction, which is then combined with the leading distance to calculate the leading error. The two sensing methods use different wavelengths and are captured simultaneously by a color industrial camera. The images of the two different wavelengths can be separated by extracting the RGB components, and the compensated tracking results are obtained after image processing.

Findings

The results of static positioning experiment indicate that the average absolute error in weld seam positioning is reduced to 0.099 mm after compensation. The real-time tracking experiments demonstrate that the proposed method preserves tracking accuracy even with changes in the sensor’s angle of deviation during welding, with the average absolute error being 0.248 mm. This method effectively enhances the precision of line laser weld seam tracking when the sensor exhibits a deviation relative to the welding direction.

Originality/value

By using the dual-sensing and dual-wavelength method for leading error compensation, the method effectively addresses the leading error issue while maintaining the advantages of the line laser seam tracking method.

This paper aims to investigate the differences in hot corrosion behavior of the GTD222 superalloy and TiC/GTD222 composite in a mixed salt of 75% Na2SO4 and 25% K2SO4 at 900°C.

Abstract

Purpose

This paper aims to investigate the differences in hot corrosion behavior of the GTD222 superalloy and TiC/GTD222 composite in a mixed salt of 75% Na2SO4 and 25% K2SO4 at 900°C.

Design/methodology/approach

The GTD222 superalloy and TiC/GTD222 nickel-based composite were prepared using selective laser melting (SLM). Subsequently, the hot corrosion behavior of the two alloys was systematically investigated in a salt mixture consisting of 75% Na2SO4 and 25% K2SO4 (Wt.%) at 900°C.

Findings

The TiC/GTD222 composite exhibited better hot corrosion resistance compared to the GTD222 superalloy. First, the addition of alloying elements led to the formation of a protective oxide film on the TiC/GTD222 composites 20 h before hot corrosion. Second, TiC/GTD222 composite corrosion surface has a higher Ti content, after 100 h of hot corrosion, the composite corrosion surface Ti content of 10.8% is more than two times the GTD222 alloy 4% Ti. The Ti and Cr oxides are tightly bonded, effectively resisting the erosion of corrosive elements.

Originality/value

The hot corrosion behavior of GTD222 superalloy and TiC/GTD222 composites prepared by SLM in a mixed salt of 75% Na2SO4 and 25% K2SO4 was studied for the first time. This study provides insights into the design of high-temperature alloys resistant to hot corrosion.

Abstract

Purpose

Intelligent new energy vehicles (INEVs) are becoming the competitive hotspot for the automobile industry. The major purpose of this study is to determine how to increase innovation efficiency through knowledge sharing and technology spill between new energy vehicle (NEV) enterprises and technology enterprises. This will help to improve the core competence of the automobile industry in China. Also, it serves as a guide for the growth of other strategic.

Design/methodology/approach

The authors construct a tripartite evolutionary game model to study the cross-border cooperative innovation problem. Firstly, the payment matrix of NEV enterprise, technology enterprise and government is established, and the expected revenue of each participant is determined. Then, the replication dynamic equations and evolutionary stability strategies are analyzed. Finally, the theoretical research is validated through numerical simulation.

Findings

Results showed that: (1) An optimal range of revenue distribution coefficient exists in the cross-border cooperation. (2) Factors like research and development (R&D) success rate, subsidies, resource and technology complementarity, and vehicles intelligence positively influence the evolution towards cooperative strategies. (3) Factors like technology spillover risk cost inhibit the evolution towards cooperative strategies. To be specific, when the technology spillover risk cost is greater than 2.5, two enterprises are inclined to choose independent R&D, and the government chooses to provide subsidy.

Research limitations/implications

The research perspective and theoretical analysis are helpful to further explore the cross-border cooperation of the intelligent automobile industry. The findings suggest that the government can optimize the subsidy policy according to the R&D capability and resource allocation of automobile industry. Moreover, measures are needed to reduce the risk of technology spillovers to encourage enterprise to collaborate and innovate. The results can provide reference for enterprises’ strategic choice and government’s policy making.

Originality/value

The INEV industry has become an important development direction of the global automobile industry. However, there is limited research on cross-border cooperation of INEV industry. Hence, authors construct a tripartite evolutionary game model involving NEV enterprise, technology enterprise and the government, and explore the relationship of cooperation and competition among players in the INEV industry, which provides a new perspective for the development of the INEV industry.

Abstract

Purpose: This chapter aims to evaluate the significant impact of Gandhian values on sustainable consumption behaviour (SCB) by applying the value-attitude-behaviour (VAB) framework. This chapter contributes by incorporating Gandhian values as one influencing factor for SCB.

Need for the Study: Values are considered as guiding principles in people’s lives. Studies suggest that values and other social and psychological factors can be vital in determining consumers’ behaviour towards sustainable consumption. There needs to be more empirical research on consumer behaviour facets of sustainable consumption for markets in India.

Methodology: The study uses partial least square structural equation modelling to empirically test proposed hypotheses and the research model of the relationship. The study results are based on data collected by administering a survey through a questionnaire confined to India.

Findings: The results indicated that Gandhian values, attitude, and sustainable consumption intention significantly influence SCB. Intention acts as a mediator between both outward and inward environmental attitudes and behaviour. The study provides directions for further research.

Practical Implications: This research study is helpful for researchers, marketers, and policymakers.

Abstract

Purpose

This study aims to examine the acceptance of adaptive learning (AL) amongst construction professionals in Singapore. It seeks to compare their perceptions and attitudes with those of professionals from other industries to assess the rate of AL adoption in the construction sector. Furthermore, the study aims to identify the factors influencing construction professionals’ intention to adopt AL technologies.

Design/methodology/approach

A questionnaire survey was conducted with 188 construction professionals and 153 non-construction professionals. By employing the extended unified theory of acceptance and use of technology (UTAUT2) and the general extended technology acceptance model for e-learning (GETAMEL), this study also explored factors influencing construction professionals’ behavioural intention (BI) towards AL adoption. An SEM-machine learning approach facilitated the evaluation of the factors’ influence on BI.

Findings

A comparative analysis of the data found that construction professionals’ intention to use AL surpassed 75%, which had no significant difference with professionals from other industries. The findings revealed that learning value (LV) and self-efficacy (SE) were statistically significant predictors of construction professionals’ intentions to use AL. Furthermore, a supervised machine learning analysis identified performance expectancy (PE) as a crucial factor in predicting these intentions.

Research limitations/implications

The study’s focus on self-reported intentions and a specific demographic limits its generalisability; further research should examine actual usage across diverse cultures.

Practical implications

The results offered insights into construction professionals’ perceptions and attitudes towards AL adoption, guiding the integration of AL into construction professional development.

Originality/value

This paper addresses a recognised gap by examining construction professionals’ perceptions and attitudes towards adopting AL.

This paper aims to find a suitable solution to degrade the C.I. Reactive Red 24 (RR24) dyeing wastewater by using sodium persulphate to recycle water and inorganic salts.

Abstract

Purpose

This paper aims to find a suitable solution to degrade the C.I. Reactive Red 24 (RR24) dyeing wastewater by using sodium persulphate to recycle water and inorganic salts.

Design/methodology/approach

The effects of temperature, the concentration of inorganic salts and Na2CO3 and the initial pH value on the degradation of RR24 were studied. Furthermore, the relationship between free radicals and RR24 degradation effect was investigated. Microscopic routes and mechanisms of dye degradation were further confirmed by testing the degradation karyoplasmic ratio of the product. The feasibility of the one-bath cyclic dyeing in the recycled dyeing wastewater was confirmed through the properties of dye utilization and color parameters.

Findings

The appropriate conditions were 0.3 g/L of sodium persulphate and treatment at 95°C for 30 min, which resulted in a decolorization rate of 98.4% for the dyeing wastewater. Acidic conditions are conducive to rapid degradation of dyes, while ·OH or SO4· have a destructive effect on dyes under alkaline conditions. In the early stage of degradation, ·OH played a major role in the degradation of dyes. For sustainable cyclic dyeing of RR24, inorganic salts were reused in this dyeing process and dye uptake increased with the times of cycles. After the fixation, some Na2CO3 may be converted to other salts, thereby increasing the dye uptake in subsequent cyclic staining. However, it has little impact on the dye exhaustion rate and color parameters of dyed fabrics.

Originality/value

The recommended technology not only reduces the quantity of dyeing wastewater but also enables the recycling of inorganic salts and water, which meets the requirements of sustainable development and clean production.

Abstract

Purpose

The purpose of this study is to conduct a comprehensive and precise investigation into the influence of office environments on employee performance. Office workers spend a considerable amount of time inside a building, and the office environment in which they work has a profound impact on their overall well-being and directly affects their effectiveness and productivity. Yet, the previous studies opted out the importance of hygiene factors like office environment and there is a need to uncover hidden causes and shed light on office environment areas that can be improved.

Design/methodology/approach

This research adopts a descriptive research design using a quantitative research method to study the relationships between office environment facilitations and employee performance. The technique of survey questionnaires was employed, and a total of 829 samples were analyzed. Measurement model, structural model and hypothesis testing using PLS-SEM software version 4.1.0.0 were briefly explained.

Findings

The study investigated the direct and indirect effects of the office environment on employee communication, interactions, productivity and performance. The findings revealed significant outcomes, indicating that the office environment does indeed have an impact on these employee-based factors. Both communication and interactions, as well as employee productivity as an indirect effect, were found to significantly mediate the connection between the office environment and employee performance.

Research limitations/implications

Insufficient data and analysis exist regarding the factors influencing the effect of employee performance on business. The constraints of time, cost and scope impede comprehensive surveys and thorough analysis. Regrettably, only four specific aspects of the office environment were examined in relation to employee performance, neglecting other significant factors. By acknowledging the potential problems highlighted in this study concerning different office concepts, organizations can endeavor to establish a more conducive working environment. It is imperative to acknowledge that the absence of a well-structured office environment that meets employees’ expectations may lead to unfavorable consequences.

Originality/value

To the best of the authors knowledge, this is the first study of office environment facilitations related to employee behavioral attitude and employee performance in Yangon, Myanmar and this study will help discover new insights of the importance of employee performance in least developing countries.

Abstract

Purpose

The literature on unethical pro-organizational behavior (UPOB) has experienced significant growth in the past decade. However, there is limited research on the effects of organizational, team and malleable individual factors on UPOB. It is also necessary to explore its adverse effects for theoretical advancement and to uncover unexplored opportunities. This study aims to systematically examine the existing body of literature on UPOB, providing thorough theoretical, contextual and methodological insights.

Design/methodology/approach

Using the preferred reporting items for systematic reviews and meta-analysis technique, the authors identified 43 articles on UPOB from journals included in the ABDC-2019 list. The authors conducted an analysis of the identified articles and categorized them using a modified version of Paul and Rosado-Serrano’s (2019) TCCM framework.

Findings

Existing literature primarily focuses on attitudinal and contextual antecedents of UPOB, neglecting individual differences and their consequences. The review suggests that certain desired employee attitudes may also lead to UPOB. In addition, the study highlights underutilization of established behavioral theories, emphasizing the need for a more inclusive theoretical framework. The exploration identifies research gaps, including in multidisciplinary and transdisciplinary studies, aiming to broaden the research scope in this field.

Research limitations/implications

The study highlights the need for a more comprehensive theoretical framework to understand UPOB.

Practical implications

It cautions organizations fostering positive employee attitudes, such as job satisfaction, workplace spirituality and organizational commitment, as these may inadvertently promote UPOB.

Social implications

Socially, the paper highlights how engaging in UPOB affects the lives of involved employees.

Originality/value

This paper’s originality arises from its methodical review and categorization of prior research on UPOB using a distinctive, multidisciplinary research framework.
