Abstract

Purpose

This paper seeks to present a fully digital, real‐time (RT) hardware‐in‐the‐loop (HIL) simulator on PC‐cluster, of electric systems and drives for research and education purposes; to use the developed system to conduct several motor drives implementation and to evaluate the motor and the control algorithm performance in RT.

Design/methodology/approach

This simulator was developed with the aim of meeting the simulation needs of electromechanical drives and power electronics systems while solving the limitations of traditional RT simulators. This simulator has two main subsystems, software and hardware. The two subsystems were coordinated together to achieve the RT simulation. The software subsystem includes MATLAB/Simulink environment, a C++ compiler and RT shell. The hardware subsystem includes FPGA data acquisition card, the control board, the sensors, and the controlled motor.

Findings

The complexity of RT implementation of motor drives is greatly reduced by utilizing this simulator. The detailed operation and implementation of this simulator are presented, together with test results and comparisons with simulated virtual environment for a permanent magnet dc and induction motors (IM). The simulator performance is adequate for both open and closed loops motor drives. The simulation time step is limited by the system Master/Target CPU's speed, the communication network type, and the complexity of the control algorithm.

Practical implications

A typical application for this system is to select and evaluate the performance of electric motors for a hybrid electric vehicle in a real vehicle environment without actually installing that component in the real vehicle.

Originality/value

The use of the developed RT simulator to achieve HIL simulation allows rapid prototyping, converter‐inverter topologies testing, motors testing, and control strategies evaluation. The transition from simulated virtual environment to the HIL mode can be performed by replacing the model of the physical system (e.g. motor) with the DAQ blocks to represent the channels connected to the physical system sensors. The use of a single environment for both simulation and HIL control provides a quick experimentation and performance comparison between the real and simulated systems.

This study aims to measure the effect of customers’ technology readiness and the quality of electronic services on customer satisfaction.

Abstract

Purpose

This study aims to measure the effect of customers’ technology readiness and the quality of electronic services on customer satisfaction.

Design/methodology/approach

The statistical sample included 410 respondents from 24 branches of a private bank. The sampling method was questionnaire. Because of the structural and organizational similarity of private banks and the elimination of nuisance variables, a bank with the most branches and customers has been selected. To test the model, equation modeling was performed to test the hypotheses. Data were collected through a self-developed structured questionnaire, which served as the measurement tool as well.

Findings

The results of the study showed that technology readiness has a significant and positive effect on customer satisfaction through the quality of self-service. Moreover, the intermediate role of perceived value in this regard was confirmed; however, the role of trust was not confirmed.

Originality/value

Previous studies have considered technology readiness as an effective factor in the quality of self-service and customer satisfaction. In this study, apart from quality of service in self-service banking and customer satisfaction, two variables of trust and perceived value have been investigated. An attempt has also been made to address some questions, including “what the effect of customer technology readiness on perceived value of self-services as well as customer satisfaction is?” and “how it is possible to improve self-service quality in modern banking based on customer expectations?” or “what effects variables such as trust and perceived value have on customer satisfaction?” Having a glance at the studies done before, it can be understood that so far, there has been no study done using a mixture of these variables, yet societies’ demands for self-service operations grow day by day. It is, therefore, mandatory to study the prerequisites associated with any actions before one is taken. The paper contributes in the following way: trust and perceived value are added to the the study because of their role in customer satisfaction. In addition, for the first time, variables have been studied, which had never been under focus in any studies in developing countries before.

Abstract

Purpose

The purpose of this paper is to problematise the concept of corruption as it is used in the African context by exposing the weaknesses in the business model used to define corruption and resource the massive yet incompetent anti‐corruption effort. The paper then aims to follow this critique by considering an alternative way of dealing with the awesome dimensions of African corruption.

Design/methodology/approach

The paper utilises in‐depth secondary source analysis, applying critical theory.

Findings

Corruption's main interpretive framework, neo‐liberalism, is exposed as dominating, business‐centric and non‐utilitarian. A new paradigm with a strong ethnographic texture is presented.

Originality/value

The paper for the first time co‐analyses two contending paradigms for the construction of African corruption in the context of the global economic crisis.

Abstract

Purpose

This paper reviews 105 Scopus-indexed articles to identify the degree, scope and purposes of machine learning (ML) adoption in the core functions of human resource management (HRM).

Design/methodology/approach

A semi-systematic approach has been used in this review. It allows for a more detailed analysis of the literature which emerges from multiple disciplines and uses different methods and theoretical frameworks. Since ML research comes from multiple disciplines and consists of several methods, a semi-systematic approach to literature review was considered appropriate.

Findings

The review suggests that HRM has embraced ML, albeit it is at a nascent stage and is receiving attention largely from technology-oriented researchers. ML applications are strongest in the areas of recruitment and performance management and the use of decision trees and text-mining algorithms for classification dominate all functions of HRM. For complex processes, ML applications are still at an early stage; requiring HR experts and ML specialists to work together.

Originality/value

Given the current focus of organizations on digitalization, this review contributes significantly to the understanding of the current state of ML integration in HRM. Along with increasing efficiency and effectiveness of HRM functions, ML applications improve employees' experience and facilitate performance in the organizations.

Abstract

Purpose

The aim of this paper is to experimentally evaluate the effectiveness of the state-of-the-art printed Arabic text recognition systems to determine open areas for future improvements. In addition, this paper proposes a standard protocol with a set of metrics for measuring the effectiveness of Arabic optical character recognition (OCR) systems to assist researchers in comparing different Arabic OCR approaches.

Design/methodology/approach

This paper describes an experiment to automatically evaluate four well-known Arabic OCR systems using a set of performance metrics. The evaluation experiment is conducted on a publicly available printed Arabic dataset comprising 240 text images with a variety of resolution levels, font types, font styles and font sizes.

Findings

The experimental results show that the field of character recognition for printed Arabic still requires further research to reach an efficient text recognition method for Arabic script.

Originality/value

To the best of the authors’ knowledge, this is the first work that provides a comprehensive automated evaluation of Arabic OCR systems with respect to the characteristics of Arabic script and, in addition, proposes an evaluation methodology that can be used as a benchmark by researchers and therefore will contribute significantly to the enhancement of the field of Arabic script recognition.

Abstract

Purpose

The main purpose of this study is to investigate the impact of various service quality dimensions, namely reliability, responsiveness, visibility, employee commitment and access to service on customer satisfaction in the private banking sector of Bangladesh. The research also investigates the relationship between customer satisfaction and loyalty and effect of demographic variables on customer satisfaction.

Design/methodology/approach

The researchers distributed 320 self-administered survey questionnaires among private banks' customers in Bangladesh and obtained 200 useable responses with a 62.5% valid response rate. The research data were analysed using confirmatory factor analysis (CFA) and structural equation modelling (SEM) approaches. Analysis of variance and logistic regression have also been used to obtain the supplementary findings.

Findings

The research findings indicate that visibility, responsiveness and employee commitment have positive and significant effect on customer satisfaction, whereas reliability and access to service are found to have insignificant influence on customer satisfaction of private banking services. The findings of this study also revealed that customer satisfaction has positive and significant relationship with customer loyalty. But except respondents' occupation type, all other demographic variables have no statistically significant relation with customer satisfaction.

Research limitations/implications

The research focused solely on the private banking sector of Bangladesh, and thus the results may not be applicable to other service sectors.

Originality/value

This study conducted on customers' perception of private banking services is based on extended service quality dimensions and its relationship with customer satisfaction towards loyalty. The present research findings are anticipated to offer the guidelines for improving the customer satisfaction and loyalty of private banking services in Bangladesh as well as other countries.
