Abstract

Purpose

The purpose of this paper is to investigate the circuit analysis differential equations, which play an important role in the field of electrical and electronic engineering, and it was necessary to propose a very simple and direct method to obtain approximate solutions for the linear or non-linear differential equations, which should be simple for engineers to understand.

Design/methodology/approach

This paper introduces a simple novel Maclaurin series method (MSM) to propose an approximate novel solution in the area of circuit analysis for linear and non-linear differential equations. These equations describe the alternating current circuit of the resistor–capacitor, which evaluates the effect of non-linear current resistance. Linear and non-linear differential equations are evaluated as a computational analysis to assist the research, which reveals that the MSM is incredibly simple and effective.

Findings

Simulation findings indicate that the achieved proposed solution using the novel suggested approach is identical to the exact solutions mentioned in the literature. As the Maclaurin series is available to all non-mathematicians, this paper reflects mostly on theoretical implementations of the numerous circuit problems that occur in the field of electrical engineering.

Originality/value

A very simple and efficient method has been proposed in this paper, which is very easy to understand for even non-mathematicians such as engineers. The paper introduced a method of the Maclaurin series to solve non-linear differential equations resulting from the study of the circuits. The MSM mentioned here will be a useful tool in areas of physical and engineering anywhere the problem of the circuits is studied.

Abstract

Purpose

The purpose of this paper is to present the problem of three‐dimensional flow of a fluid of constant density forced through the porous bottom of a circular porous slider moving laterally on a flat plate.

Design/methodology/approach

The transformed nonlinear ordinary differential equations are solved via the homotopy perturbation method (HPM) for small as well as moderately large Reynolds numbers. The convergence of the obtained HPM solution is carefully analyzed. Finally, the validity of results is verified by comparing with numerical methods and existing numerical results.

Findings

Close agreement of the two sets of results is observed, thus demonstrating the accuracy of the HPM approach for the particular problem considered.

Originality/value

Interesting conclusions which can be drawn from this study are that HPM is very effective and simple compared to the existing solution method, able to solve problems without using Padé approximants and can therefore be considered as a clear advantage over the N.M. Bujurke and Phan‐Thien techniques.

Abstract

Purpose

The purpose of this paper is to apply exp‐function method to construct generalized solitary and periodic solutions of Fitzhugh‐Nagumo equation, which plays a very important role in mathematical physics and engineering sciences.

Design/methodology/approach

The authors apply exp‐function method to construct generalized solitary and periodic solutions of Fitzhugh‐Nagumo equation.

Findings

Numerical results clearly indicate the reliability and efficiency of the proposed exp‐function method. The suggested algorithm is quite efficient and is practically well suited for use in these problems.

Originality/value

In this paper, the authors applied the exp‐function method to obtain solutions of the Fitzhugh‐Nagumo equation and show that the exp‐function method gives more realistic solutions without disturbing the basic physics of the physical problems.

Abstract

Purpose

The purpose of this paper is to unfold the relationship between service quality and level of performance of conventional and Islamic banks. Also, it intends to uncover what are the features of service quality which can raise the level of performance either in conventional banks or Islamic banks. There is rare literature available that focused on comparative study between above stated banking systems based on emerging parameters of SERVQUAL model.

Design/methodology/approach

To meet the objectives of this investigation, research data has been from 450 customers who have had accounts and dealings with conventional and Islamic banks in the previous five years. The customers are selected based on cluster sampling from regional offices of conventional and Islamic banks.

Findings

The collected data have been analyzed by using confirmatory factor analysis (CFA) technique followed by common method variance (CMV), multiple regression test and independent sample t-test used to examine the parameters of service quality in the context of banks performance. The purpose of CFA is to find the model validity, while multiple regression and t-test is performed in order to examine the influence of service quality parameters on banks performance.

Originality/value

The study used compliance as a one of the emerging and unique dimension of service quality. This dimension is rarely investigated in the context of measuring the level of bank performance of conventional and Islamic banking systems. Findings reveal responsiveness and assurance is the strongest predictor of conventional banking performance. Compliance and reliability has significant and positive impact on the level of performance of Islamic banks. Moreover, the study has practical implications for the top management and stakeholders of conventional and Islamic banks to increase the level of performance by using SERVQUAL model.

Abstract

Purpose

This study aims to examine the moderation role of human resource management (HRM) in the relationship between risk management and project success of electrical power transmission and distribution systems.

Design/methodology/approach

A questionnaire was used to collect data from the electrical companies of Pakistan. A 100 professionals working in power sector companies took part in it. To analyze the impact, correlation analysis and linear regression analyses have been performed using IBM SPSS V-22®.

Findings

The linear regression results obtained the significant impact of risk management on project success (p < 0.05). The moderated regression represented a change in the percentage variation (R2) that is 0.463 without moderating effect and it increased to 0.528 after including human resource (HR) moderator indicating a moderating effect of HRM.

Research limitations/implications

Because of the theoretical significance of growing awareness about the importance of HRM and development, this study has significant practical implications. This study can be implemented practically to support the business strategies of the organization and HR competency and engineering will contribute in shaping those business strategies as well.

Originality/value

This study provides evidence on the impact of HRM on project success as a moderating variable with risk management. The study shows the increment in the ratio of project success in the electrical sector of Pakistan. This research provides the importance of HRM functions in the electrical sector of Pakistan.

Abstract

Purpose

This study aims to investigate how abusive supervisor affects knowledge hiding (KH). Specifically, this study investigates employee silence as a mediating mechanism between abusive supervision and employees’ KH. Further, psychological ownership is examined as a buffer between abusive supervision and employee silence.

Design/methodology/approach

KH has become a major issue for both manufacturing and service sectors. Therefore, this study collected data from 322 employees working in manufacturing and service sectors through “Google Forms” during COVID-19. The respondents were contacted through LinkedIn platform between January and July 2021.

Findings

This study noted that when employees working in high-power distance cultures perceive their leaders/supervisors as abusive, they avoid confrontation and engage in silent behavior, which positively affects their KH behavior. However, employees with a high level of psychological ownership are less likely to respond to their abusive supervisors through silence because such employees feel a greater sense of belongingness and prefer to benefit their organization.

Research limitations/implications

This study used a cross-sectional design that restricts causality. However, the findings of this study suggest management to focus on leadership style to minimize KH at the workplace.

Originality/value

To the best of the authors’ knowledge, this study is the first to explore the underlying mechanism (employee silence) and boundary condition (psychological ownership) to explain the association between abusive supervision and KH.
