Abstract

Purpose

The purpose of this paper is to propose distributed learning-based three different metaheuristic algorithms for the identification of nonlinear systems. The proposed algorithms are experimented in this study to address problems for which input data are available at different geographic locations. In addition, the models are tested for nonlinear systems with different noise conditions. In a nutshell, the suggested model aims to handle voluminous data with low communication overhead compared to traditional centralized processing methodologies.

Design/methodology/approach

Population-based evolutionary algorithms such as genetic algorithm (GA), particle swarm optimization (PSO) and cat swarm optimization (CSO) are implemented in a distributed form to address the system identification problem having distributed input data. Out of different distributed approaches mentioned in the literature, the study has considered incremental and diffusion strategies.

Findings

Performances of the proposed distributed learning-based algorithms are compared for different noise conditions. The experimental results indicate that CSO performs better compared to GA and PSO at all noise strengths with respect to accuracy and error convergence rate, but incremental CSO is slightly superior to diffusion CSO.

Originality/value

This paper employs evolutionary algorithms using distributed learning strategies and applies these algorithms for the identification of unknown systems. Very few existing studies have been reported in which these distributed learning strategies are experimented for the parameter estimation task.

Abstract

Purpose

The purpose of this paper is to analyse service quality in the automobile maintenance and repair industry. A conceptual structural model is developed to investigate the impact of service quality, perceived service fairness and convenience on customer service satisfaction. The impact of service satisfaction and brand trust on word of mouth (WOM) is also explored, and the study assesses the mediating effect of customer service satisfaction on the relationship between service quality and WOM.

Design/methodology/approach

Data from a questionnaire-based survey of 259 users of automobile maintenance and repair centres were analysed using covariance-based structural equation modelling.

Findings

The findings indicate that service quality dimensions (reliability, responsiveness and empathy), perceived service fairness and convenience are positively associated with customer service satisfaction, and that service satisfaction and trust positively influence WOM. The findings support the mediating effect of service satisfaction on the relationship between reliability and responsiveness and WOM.

Research limitations/implications

The study’s main limitation is the cross-sectional design, which limits the generalisability of the findings.

Practical implications

To ensure customer satisfaction and generate trust and WOM, automobile maintenance and repair service centres should improve reliability, responsiveness and empathy, as well as perceived service fairness and convenience.

Originality/value

The study demonstrates that the reliability and responsiveness dimensions of service quality are the most significant predictors of customer service satisfaction in the automobile maintenance and repair industry.

Abstract

Purpose

This paper aims to assess the relationship between academic burnout-student engagement relationships on management students of the Delhi-NCR region of Northern India. It further attempts to study the moderating impact of internal locus of control and mediating impact of loneliness on the academic burnout-student engagement relationship.

Design/methodology/approach

The data was collected using standardized instruments from 264 respondents. Descriptive statistics, correlation and moderated-mediated regression analysis were used to test the hypotheses.

Findings

The study found a negative association between student engagement and academic burnout and loneliness. A positive association between academic burnout and loneliness and a moderating impact of internal locus of control on academic burnout and student engagement relationship. Loneliness acted as a partial mediator for the moderated relationship between the academic burnout-student engagement relationship.

Research limitations/implications

Sample size and sampling units are the limitations of the study.

Practical implications

The conclusion of the presented study offers different inferences including validating the self-determination theory (Ryan and Deci, 2000) and possible courses of actions to be taken by academic institutions and students themselves. It ranges from careful investigation of student’s behaviors, design and implements collaborative projects along with student’s involvement in social networking based groups for collaborations and help.

Social implications

With the help of the study, the society including parents, family, friends, officials and academicians at educational institutions can offer useful insights to students through recreational and social activities for behavior modifications.

Originality/value

The major contribution of the study is to understand the psyche of the budding professionals perceiving increased stress and pressure. Limited studies are found in the Indian context and no studies in the past have used the study variables together. Internal locus of control as a personality variable has not been studied with respect to student’s burnout and engagement. Furthermore, none of the studies done in the past have deliberated upon loneliness with respect to the student community.

Abstract

Purpose

In complementary metal-oxide-semiconductor (CMOS) logic circuits, there is a direct square proportion of supply voltage on dynamic power. If the supply voltage is high, then more amount of energy will be consumed. Therefore, if a low voltage supply is used, then dynamic power will also be reduced. In a mixed signal circuit, there can be a situation when lower voltage circuitry has to drive large voltage circuitry. In such a case, P-type metal-oxide-semiconductor of high-voltage circuitry may not be switched off completely by applying a low voltage as input. Therefore, there is a need for level shifter where low-voltage and high-voltage circuits are connected. In this paper the multi-scaling voltage level shifter is presented which overcomes the contention problems and suitable for low-power applications.

Design/methodology/approach

The voltage level shifter circuit is essential for digital and analog circuits in the on-chip integrated circuits. The modified voltage level shifter and reported energy-efficient voltage level shifter have been optimally designed to be functional in all process voltage and temperature corners for VDDH = 5V, VDDL = 2V and the input frequency of 5 MHz. The modified voltage level shifter and reported shifter circuits are implemented using Cadence Virtuoso at 90 nm CMOS technology and the comparison is made based on speed and power consumed by the circuit.

Findings

The voltage level shifter circuit discussed in this paper removes the contention problem that is present in conventional voltage level shifter. Moreover, it has the capability for up and down conversion and reduced power and delay as compared to conventional voltage level shifter. The efficiency of the circuit is improved in two ways, first, the current of the pull-up device is reduced and second, the strength of the pull-down device is increased.

Originality/value

The modified level shifter is faster for switching low input voltage to high output voltage and also high input voltage to low output voltage. The average power consumption for the multi-scaling voltage level shifter is 259.445 µW. The power consumption is very less in this technique and it is best suitable for low-power applications.
