Abstract

Purpose

This paper aims to present a state-of-the-art review in various fields of interest, leading to a new concept of bio-inspired control of small aircraft. The main goal is to improve controllability and safety in flying at low speeds.

Design/methodology/approach

The review part of the paper gives an overview of artificial and natural flow sensors and haptic feedback actuators and applications. This background leads to a discussion part where the topics are synthesized and the trend in control of small aircraft is estimated.

Findings

The gap in recent aircraft control is identified in the pilot–aircraft interaction. A pilot’s sensory load is discussed and several recommendations for improved control system architecture are laid out in the paper.

Practical implications

The paper points out an opportunity for a following research of suggested bio-inspired aircraft control. The control is based on the artificial feeling of aerodynamic forces acting on a wing by means of haptic feedback.

Originality/value

The paper merges two research fields – aircraft control and human–machine interaction. This combination reveals new possibilities of aircraft control.

Abstract

Purpose

The purpose of this study is to lead to an improvement in pilot-aircraft interaction. The goal of the performed tests is an assessment of haptic feedback, which mediates flight parameters to the pilot. Pedals indicate side-slip angle by vibrations, whereas a sliding element inside the control stick is able to continuously indicate both angles of attack and side-slip.

Design/methodology/approach

Haptic feedback applied on rudder pedals and control stick were tested on a flight simulator and flight tests in a couple of tasks. Pilot workload, readability of feedback and side-slip were then evaluated when the flight was turning.

Findings

As a useful instrument for aircraft control, haptic feedback was assessed. The feedback settings were then individually perceived, and haptic feedback slightly improved side-slip while turning in a flight test; however, the results are not statistically significant.

Practical implications

The tests provided promising results for human pilot performance. The training phase and personal settings of haptic feedback is an approach for improving the performance of human pilots.

Originality/value

The designed and tested device is a unique tool for improving pilot-aircraft interaction. This study brings valuable experiences from its flight simulator and in-flight tests.

Abstract

Purpose

This study aims to consider a five-factor model to evaluate the service quality of solar product companies in the context of rural Punjab (India) and validate the proposed model. In addition, the study considered the factors which affect the service quality of solar product companies.

Design/methodology/approach

A five-factor model of service quality has been tested for reliability and validity by confirmatory factor analysis. For determining satisfaction of the solar product users, SERVQUAL model/gap analysis has been applied. Five dimensions, namely tangibility, reliability, responsiveness, assurance and empathy have been considered to assess the overall satisfaction level. A modified scale of Parasuraman incorporated in 1985 has been used as a survey instrument for research. A sample size of 345 solar submersible pump users was selected.

Findings

The study concluded that dimensions such as reliability, responsiveness, assurance and empathy have lesser gap. The major gap has been found in the tangibility dimension which includes variables like modern design of solar energy products, facilities and attractiveness, variety of solar products and performance of solar products, etc.

Research limitations/implications

As primary data are concerned, the biasness of the respondents may affect the results of the study. The survey has been conducted in the Punjab region, and a sample size is 345 only which may not reflect the broader picture.

Practical implications

Solar energy has huge benefits in the Indian agriculture sector. The erratic state of power supply in India casts important costs on agriculture productivity. One such segment concerns systems, an important input for agriculture production. The study has implications for solar energy product manufacturers, as it makes them aware about customer perception toward services of solar product companies.

Social implications

To decrease pollution and to save the environment, solar energy technologies have a good potential energy source and to meet the global energy demand, as it is the most promising and reliable energy source.

Originality/value

The existing studies in the context of service quality of solar product companies in Punjab have been majorly confined to proposing key drivers toward adoption of renewable energy sources. By providing an insight into the satisfaction level of farmers for solar submersible pumps, the proposed study attempts to fill the gap. As the study relates to solar product users in rural Punjab, the findings will be of additional value to solar product companies which are manufacturing solar products. Therefore, it is expected that this research will fill the gap in literature by studying empirically the service quality of solar product companies.

Abstract

Purpose

The purpose of this paper is to examine the interrelationship of marketing, accounting and auditing with corporate social responsibility (CSR) to determine the benefit of CSR marketing, the responsibility of Board of Directors (BODs) with CSR accounting and the duty of external auditors with CSR that has influence on corporate sector.

Design/methodology/approach

This paper uses exploratory and qualitative data obtained from multiple research methods, to investigate benefit of CSR marketing, the responsibility of BODs with CSR accounting and the duty of external auditors with CSR and of its practices by companies’ websites, google search, annual reports and CSR reports from all listed companies in the Muscat Securities Market, Oman. The data are used to critically examine and revise a previously published explanatory framework that identifies interrelationship of CSR marketing, accounting with CSR and auditing with CSR.

Findings

Results indicate that CSR marketing, CSR accounting and CSR auditing are closely interrelated for accepting and implementing CSR requirements by corporates. This finding suggests that the benefit of CSR marketing, the responsibility of BODs with CSR accounting and the duty of external auditors with CSR has positively influence on corporate sector. The finding helps to build good image by corporates.

Practical implications

Organizations from developing countries such as Oman should be aware of CSR marketing, CSR accounting and CSR auditing that affects decisions with CSR adoption and implementation by organizations that could also lead to competitive advantage when it operates in developed countries. Though, organizations in developed countries are also equip for higher expectations by applying innovative CSR initiatives.

Originality/value

To the best of the author’s knowledge, this is the first academic literature review on interrelationship of marketing, accounting and auditing with CSR based on evidence from an Oman context. The paper contributes by exploring the benefit of CSR marketing, the responsibility of BODs with CSR accounting and the duty of external auditors with CSR which influence on corporate sector.
