Abstract

Purpose

This study aims to explore the integration of machine learning (ML) in tribology to optimize lubrication interval decisions, aiming to enhance equipment lifespan and operational efficiency through wear image analysis.

Design/methodology/approach

Using a data set of scanning electron microscopy images from an internal combustion engine, the authors used AlexNet as the feature extraction algorithm and the J48 decision tree algorithm for feature selection and compared 15 ML classifiers from the lazy-, Bayes and tree-based families.

Findings

From the analyzed ML classifiers, instance-based k-nearest neighbor emerged as the optimal algorithm with a 95% classification accuracy against testing data. This surpassed individually trained convolutional neural networks’ (CNNs) and closely approached ensemble deep learning (DL) techniques’ accuracy.

Originality/value

The proposed approach simplifies the process, enhances efficiency and improves interpretability compared to more complex CNNs and ensemble DL techniques.

Abstract

Purpose

This study is a systematic review of mobile banking services. Its main objective is to provide a state-of-the-art review of this particular growing type of services. It inventories and assesses the most significant determinants of and barriers to consumers' adoption of mobile banking. Moreover, it identifies the most common consequences of this adoption.

Design/methodology/approach

By using three major academic databases (ABI/INFORM global, Web of Science and Business Source Premier), this paper selected 76 manuscripts and produced a systematic review that exposes the main theories, conceptual frameworks and models used to explain consumers' adoption of mobile banking.

Findings

The results show that the TAM (technology of acceptance model), followed by the UTAUT (unified theory of acceptance and usage of technology), are still the main conceptual frameworks and models adopted and adapted by scholars to explain consumers' use or intention of using mobile banking. Using the vote counting method, a myriad of antecedents and consequences that are frequently used in the literature of mobile banking are reported. These were categorized into five main perspectives: (1) m-banking attributes-based perspective, (2) customer-based perspective, (3) social influence-based perspective, (4) trust-based perspective and (5) barriers-based perspective.

Originality/value

An integrated model regrouping and relating the five perspectives is proposed, leading to intriguing implications for both academics and practitioners.

Abstract

Purpose

In recent years, numerous banks have introduced live chat systems to their mobile banking (m-banking) applications to help customers address problems that arise while using m-banking. However, few researchers have investigated bank customers' perceptions of live chat in the context of m-banking, known as mobile chat. The present study attempts to fill this research gap and identify potential factors affecting bank customers' intention and attitude toward using mobile chat from the perspective of functional and expected advantages.

Design/methodology/approach

A research model was developed integrating three technological characteristics of mobile chat (mobility, reachability and convenience) identified from the mobile service and self-service technology literature with user beliefs involving performance expectancy, effort expectancy and facilitating conditions specified by the unified theory of acceptance and use of technology. The proposed model was evaluated using data collected from a field survey of 268 customers with experience in Internet or m-banking at an international bank in Taiwan. The mediating effects of attitude on the relationship between intention and its predictors were also measured.

Findings

The results suggest that reachability and convenience influence performance expectancy whereas effort expectancy is affected by all the technological characteristics. Additionally, customers' intention is determined by attitude, effort expectancy and facilitating conditions whereas their attitude depends on the three constructs of user beliefs.

Research limitations/implications

The development of user behavioral research in intelligent customer engagement is lacking in the m-banking literature. This study sheds light on Internet banking and m-banking customers' viewpoints and the salient determinants of their intention and attitude toward using mobile chat. Therefore, the findings allow a broader understanding of customer engagement applications in the banking sector.

Practical implications

The research findings would help banks not only better understand how to deploy useful mobile applications for improving the effectiveness of their mobile service development but also develop adequate mobile strategies to engage with customers more intelligently.

Originality/value

This research provides valuable insight into the relationship between the adoption of intelligent customer engagement tools and the improvement of customer support performance in the context of m-banking. Moreover, this study is among the first to identify the potential mobile technological factors that might affect bank customer expectations from mobile chat applications.

Abstract

Purpose

The main purpose of this study is to analyse the thermomechanical behavior of the dry contact between the brake disc and pads during the braking phase.

Design/methodology/approach

The simulation strategy is based on computer code ANSYS11. The modeling of transient temperature in the disc is actually used to identify the factor of geometric design of the disc to install the ventilation system in vehicles. The thermal‐structural analysis is then used coupling to determine the deformation and the Von Mises stress established in the disc, the contact pressure distribution in pads.

Findings

The analysis results showed that temperature field and stress field in the process of braking phase were fully coupled.

Originality/value

The results are satisfactory when compared with those of the specialized literature.

Abstract

Purpose

This article aims to question the role of attitude towards behavior and bank reputation in the relationship between consumer compatibility and behavioral intention.

Design/methodology/approach

Using survey data from 640 mobile bank users in a developing country setting, the authors explored the conditional effects of users' compatibility on their future intention to use mobile banking services through attitude towards use as a function of perceived corporate reputation.

Findings

The results indicated that the attitude towards using mobile banking services has a partial mediating role in the relationship between compatibility and future intention to use. This indirect path depends on the reputation of the bank.

Originality/value

The original contribution of this study is to detail the mechanism between compatibility and usage intention that emerges within the scope of the model the authors propose and to realize this through the Johnson-Neyman approach.

Abstract

Purpose

Bearings are critical components used to support loads and facilitate motion for rotating and sliding parts of the machinery. Bearing malfunctions can cause catastrophic failures. Hence, failure analysis and endeavors to improve bearing performance are essential discussions for worldwide designers, manufacturers and end users of vital machinery. This study aims to investigate a type of roller bearing from the railway industry with premature failures. The task arises because locomotives’ maintenance and service life quality are vital to railway operations while providing transportation services for the nation. To assist in maintaining the designated locomotives, the present study scrutinizes the causes of failure of heavy-duty roller bearings from locomotive bogie axleboxes.

Design/methodology/approach

It is intended to inspect this bearing service life and statistically scrutinize its design parameters to reveal the failures’ shortcomings and origins. The significant measures include examinations of their failures’ primary and vital factors by comparing them with a real-life service history of 16 roller bearings of the same type. The bearings come from the axleboxes of a locomotive bogie with an axle load of 20 tons. The bearing loads are estimated using the EN13104 standard document and confirmed by the finite element method using ABAQUS engineering software. To validate the finite element modeling results, the bearings’ stress analysis is performed using the Hertzian contact theory that demonstrated perfect conformity. The said methods are also used to search for the areas susceptible to failures in these bearings. With the inclusion and exploitation of the bearing maintenance conditions and the logbook recordings of the locomotives for the past seven years, the critical cause for this type of bearing’s failures is surveyed and discussed.

Findings

With the inclusion and exploitation of the bearing maintenance conditions and the logbook recordings of the locomotives for the past seven years, the critical cause for this type of bearing’s failures is surveyed and discussed. As a crucial result, it is found that deprived maintenance and inadequate lubrication are the root causes of the loss of the selected bearings.

Originality/value

For the designated locomotives, the origins of the heavy-duty roller bearing failures and its design shortcomings are revealed by examining and comparing them with a real-life service history of many of the same types of bearings. The novelty of the research is in using the combination of the methods mentioned above and its decent outcome.

Abstract

Purpose

The purpose of this paper is to investigate the multidimensional concept of mobile banking service quality (security/privacy, practicity, design/aesthetics, enjoyment and sociality) and the impact of the latter on the quality of the relationship (commitment, trust and satisfaction) between consumers and their primary financial institution.

Design/methodology/approach

An online survey was conducted using a sample of 375 respondents, all owners of a mobile device and all accustomed to conducting banking activities on mobile platforms. Results were analyzed using structural modeling techniques (EQS 6.1).

Findings

Findings confirm that trust significantly and positively impacts commitment/satisfaction. Mobile banking service quality dimensions also influence trust and commitment/satisfaction. Trust is associated with security/privacy and practicity (regarded as utilitarian factors), while commitment/satisfaction is driven by enjoyment and sociality (dimensions more hedonic by nature). No link is found between interface design and either trust or commitment/satisfaction.

Originality/value

This study contributes to bank marketing theory since it is the first to demonstrate how key mobile banking service quality dimensions drive customer perceptions of relationship quality. In doing so, this research extends beyond mobile adoption (short term) by addressing customer engagement with financial institutions and issues relating to relationship quality (long term). Regarding managerial implications, findings signal to marketers in the financial services industry the importance of not underestimating the power of hedonic factors (sociality and enjoyment) when developing mobile platforms. These dimensions are often overlooked in the banking industry, a sector in which consumers are believed to be mostly driven by utilitarian motives.

Abstract

Purpose

The purpose of this study is to examine the components of the utilitarian and hedonistic dimensions of the quality of mobile banking services, their impact on customer satisfaction, as well as the effects of satisfaction on word of mouth (WOM) and intention to use.

Design/methodology/approach

The analysis includes 307 mobile banking users in the Republic of Serbia. Reliability analysis, confirmatory factor analysis, structural equation modelling and multigroup analysis are applied in the paper.

Findings

The results show that security/privacy, perceived usefulness, perceived ease of use, design and enjoyment are important drivers of customer satisfaction, and that satisfaction has very strong effects on WOM and intention to use. In addition, there are apparent differences in the relationships between the two groups of respondents observed: innovators and followers.

Originality/value

The originality of the paper lies in the innovative model that includes a combination of the TAM model and the utilitarian/hedonistic dimension of the quality of mobile banking services. An element of the study which is of particular value is its segmentation of customers into innovators and followers – dividing respondents into two groups depending on whether they are among the first people in their environment to start using mobile banking services.

Abstract

Purpose

The purpose of this paper is to classify live chat service users in the banking industry and provide relevant descriptive information on each group to be able to suggest appropriate strategies to managers.

Design/methodology/approach

A total of 682 panelists from a large Canadian polling firm self-administer a web-based questionnaire. Respondents are users of financial sector live chat services. Two-step cluster analysis was performed.

Findings

Four groups emerge from the analysis. Young frequent users (Group 1) attach dominant importance to speed of service, whereas computer users (Group 3) and conservative users (Group 4) who avail themselves of live chat services via computer focus on ease of use.

Practical implications

This study, which details four groups of live chat service users in the banking industry, enables managers to better adapt their strategies to the different market segments with a view to providing customers with better quality service and enhancing their experience.

Originality/value

The study presents the first live chat service classification to detail user profiles and examine differences at the before, during and after phases of the user experience. Findings enrich the body of academic literature in the service sector, in particular literature focusing on customer service in the banking industry. The paper also provides an interesting managerial framework for the implementation of successful, segment-specific strategies.

Abstract

Purpose

This paper aims to investigate the effect of misalignment on wear of spur gears and on oil degradation using online sensors.

Design/methodology/approach

The misalignment effect on gears is created through a self-alignment bearing, and is measured using laser alignment system. Several online sensors such as Fe-concentration sensor, moisture sensor, oil condition sensor, oil temperature sensor and metallic particle sensor are installed in the gear test rig to monitor lubricant quality and wear debris in real time to assess gearbox failure.

Findings

Offset and angular misalignments are detected in both vertical and horizontal planes. The failure of misaligned gear is observed at both the ends and on both the surfaces of the gear teeth. Larger-size ferrous and non-ferrous particles are traced by metallic particle sensor due to gear and seal wear caused by misalignment. Scanning electron microscope (SEM) images examine chuck, spherical and flat platelet particles, and confirm the presence of fatigue (pitting) and adhesion (scuffing) wear mechanism. Energy-dispersive X-ray spectroscopy analysis of SEM particles traces carbon (C) and iron (Fe) elements due to gear failure.

Originality/value

Gear misalignment is one of the major causes of gearbox failure and the lubricant analysis is as important as wear debris analysis. A reliable online gearbox condition monitoring system is developed by integrating wear and oil analyses for misaligned spur gear pair in contact.
