Abstract

Purpose

Extensive efforts have been conducted on the improvement of torque ripple in switched reluctance motor (SRM) drive. The purpose of this paper is to estimate initial on time of pulse-width modulation (PWM) and turn-off angle using the motor speed and rotor angle by fuzzy logic.

Design/methodology/approach

A fuzzy logic control together with the PWM technique and turn-off angle are used to improve torque ripple and dynamic response.

Findings

After determining initial on time of PWM, the rise slope of phase current is increased.

Research limitations/implications

Future work will consider to increase the complex of the fuzzy control to adaptively tune parameters and achieve excellent results.

Practical implications

The experimental results of the proposed method are presented to show the effectiveness.

Originality/value

This paper achieves SRM control by one special PWM technique which is seldom studied.

Abstract

Purpose

First, this study aims to investigate the effects of quality perceptions (i.e. system quality, information quality and service quality) and perceived ubiquity on engineers’ perceived benefits and perceived user-friendly of mobile knowledge management systems (MKMS). Second, it aims to examine the influence of perceived benefits and perceived user-friendly on MKMS adoption intention.

Design/methodology/approach

Quantitative empirical research using an integrated technology acceptance model and information systems success model was used, among semiconductors engineers in Malaysia. There were only 375 usable responses collected, which are at a response rate of 59.52%. The partial least squares version 3.0 was used to analyze the valid data collected.

Findings

The results suggest that service quality plays an important role that would increase the engineers’ perception of MKMS benefits and its user-friendliness. Intention to adopt MKMS was found to be strongly predicted by perceived MKMS benefits as compared to perceived user-friendly.

Practical implications

The findings are valuable for managers, engineers, knowledge management (KM) practitioners, MKMS developers and mobile device producers to enhance MKMS adoption intention.

Originality/value

Despite KM has been well accepted and established in the management science and practice area of study, yet it is still neglected in a “mobile” context. Accordingly, this paper contributes to the research gap.

Abstract

Purpose

The purpose of this paper is to identify the antecedents of successful organizational cross-border knowledge transfer and also the relationship among the antecedents for sustainable competitive advantage.

Design/methodology/approach

First, a focus group study was conducted to identify major constructs and map out the proposed framework. This is then followed by questionnaire survey from 210 Malaysian multimedia super corridor (MSC) status corporations as recipients. Their international business affiliates refer to any organizations located outside Malaysia with which the recipient firm has a relationship. Data were analysed using SPSS.

Findings

The findings suggest that the perceived value of the knowledge, relational dimension and cognitive dimension, as well as recipient learning intent and the attractiveness of a foreign source are significant related to the effectiveness of organizational cross-border knowledge transfer.

Research limitations/implications

Because this research only covered 210 MSC status corporations, future research can try to have more coverage on other industry to have larger sample size for generalizability purposes. Other factors such as organizational and context characteristics can be added as antecedents to strengthen the framework for effective knowledge transfer.

Practical implications

The empirical findings can be used as a guideline for MSC status firms to undergo a self-check and help them rethink and reposition themselves in light of the findings. It helps MSC status corporations to frame their organizational cross-border knowledge transfer activities to enable the creation and application of knowledge which should allow them to drive the capability of creating and retaining a greater value onto their core business competencies.

Originality/value

This study provides valuable insights to help creating a successful foundation for organizational cross-border knowledge transfer. This study is also among few studies to examine the critical antecedents in successful organizational cross-border knowledge transfer from a multidimensional perspective in Malaysia.
