The purpose of this paper is to provide a knowledge-enabled digital twin for smart design (KDT-SD) of aircraft assembly line (AAL) to enhance the AAL efficiency, performance and visibility. Modern AALs usually need to have capabilities such as digital-physical interaction and self-evaluation that brings significant challenges to traditional design method for AAL. The digital twin (DT) combining with reusable knowledge, as the key technologies in this framework, is introduced to promote the design process by configuring, understanding and evaluating design scheme.

The proposed KDT-SD framework is designed with the introduction of DT and knowledge. First, dynamic design knowledge library (DDK-Lib) is established which could support the various activities of DT in the entire design process. Then, the knowledge-driven digital AAL modeling method is proposed. At last, knowledge-based smart evaluation is used to understand and identify the design flaws, which could further improvement of the design scheme.

By means of the KDT-SD framework proposed, it is possible to apply DT to reduce the complexity and discover design flaws in AAL design. Moreover, the knowledge equips DT with the capacities of rapid modeling and smart evaluation that improve design efficiency and quality.

The proposed KDT-SD framework can provide efficient design of AAL and evaluate the design performance in advance so that the feasibility of design scheme can be improved as much as possible.

The purpose is to understand the importance of brand experience in the Taiwan hotel branding process; also, this study is to investigate the moderating effect of brand experience on the relationship between brand positioning and non-financial brand performance in Taiwan upscale hotels, focusing on mainland Chinese tourists.

The structural equation modeling (SEM) analysis was used to conduct questionnaire analysis. This study examined data collected from Chinese tourists who stayed at Taiwan upscale hotels.

The brand experience of an upscale hotel brand can affect its brand image, product attributes, brand loyalty and customer satisfaction. By investigating the moderating effect of brand experience, the study revealed the brand image perceptions of hotel guests with a positive brand experience to significantly influence non-financial brand performance. The product attribute perceptions of hotel guests with a more positive brand experience were also found to have a more significant effect on nonfinancial brand performance.

In the highly competitive hotel industry, the application of brand experience to marketing practice has drawn much industry attention. There is a strong possibility that upscale hotel companies will eventually find value in adopting the measurement instruments and suggestions presented here to assess and guide their marketing practices.

This paper aims to evaluate diethylenetriamine (DETA) as an inhibitor on Q235 (Gr. D) steel in ammonia flue gas desulfurization (AFGD) system.

This research was carried out by weight loss, electrochemical measurements, scanning electron microscopy and X-ray photoelectron spectrometry. The effects of DETA on crystallization of ammonium sulfate and its co-crystallization were also investigated by X-ray diffraction and infrared spectroscopy.

The inhibition efficiency of DETA reached a maximum value of 98.96 per cent. DETA is postulated to adsorb on Q235 steel surface, resulting in the formation of a protective film by the accumulation of many flat particles, and the thickness of protective film is 8 μm. DETA had no effect on the crystallization of ammonium sulfate product.

DETA can be used in AFGD system as an inhibitor to protect the equipment well.

This study aims to address research gaps by constructing critical success factors (CSFs) in the context of green hotel investment in Taiwan. It contributes to the domain knowledge to cultivate Taiwan’s green hotel development in the future.

The authors secured 20 prominent green hotel management/owners/architects as crucial informants. The first stage used the Delphi method to collect expert opinions (i.e. CSFs) and the second stage applied the analytic hierarchy process to analyze the importance of CSFs.

The results show that the “financial investment benefits” is considered the most crucial success factor for the green hotel investment. However, to balance long-term economic development with environmental impact, green hotel investors should consider other aspects of the research to sustain future financial performance returns.

Further studies should consider regional characteristics to accommodate geographic/social differences and hotel types to explore possible CSFs for the green hotel investment. The authors suggest including panel experts from government officials and prominent scholars to represent a broader but different view on subject matters. They also offer implications for investors’ governmental policies, hotelier cognition and customer-related aspects in green hotel investment.

This study built a hierarchical framework based on the CSF concept by evaluating priority differences between hotel management and hotel owners/architects. Such findings help investors’ effective decision-making through considering factors’ relative importance for green hotel investments.

This study aims to use the polynomial approximation method based on the Pascal polynomial basis for obtaining the numerical solutions of partial differential equations. Moreover, this method does not require establishing grids in the computational domain.

In this study, the authors present a meshfree method based on Pascal polynomial expansion for the numerical solution of the Sobolev equation. In general, Sobolev-type equations have several applications in physics and mechanical engineering.

The authors use the Crank-Nicolson scheme to discrete the time variable and the Pascal polynomial-based (PPB) method for discretizing the spatial variables. But it is clear that increasing the value of the final time or number of time steps, will bear a lot of costs during numerical simulations. An important purpose of this paper is to reduce the execution time for applying the PPB method. To reach this aim, the proper orthogonal decomposition technique has been combined with the PPB method.

The developed procedure is tested on various examples of one-dimensional, two-dimensional and three-dimensional versions of the governed equation on the rectangular and irregular domains to check its accuracy and validity.

Technological innovation is crucial for businesses to achieve development and profitability through enhancing core capabilities and differentiating competitive advantages. The key to organisational survival is boosting innovation performance focused on technological innovation, as SMEs lack resources and competencies compared to large companies. Entrepreneurship is a topic of active research to overcome SMEs’ resource and size limits. This is because entrepreneurs’ capabilities are considered more important in small and medium-sized enterprises closely related to corporate success than in large enterprises that can receive organisational support. In addition, a company’s holding capacity is a direct driver of creating differentiated competitiveness because it can pursue product differentiation through high levels of market capabilities and technology capabilities. Therefore, this study attempts to demonstrate entrepreneurship and technological innovation for SMEs. Reviewing previous studies, the authors derive the organisational capabilities needed by the organisation for innovation and examine how these organisational capabilities (technological, market, and operational capabilities) relate to entrepreneurship and technological innovation.

The study examines the relationship between CEO characteristics and corporate social responsibility (CSR) in China. Previous studies showed that good CSR behaviour could enhance the firm’s financial performance. CEOs are responsible for major decision-making, including CSR policies. This chapter uses all A-share listed firms in China from 2011 to 2020. The authors find that CEO’s gender, age, educational background, and career experience have positive relationships with CSR. This chapter enriches the current literature on the effects of CEO characteristics and highlights the important roles of CEO characteristics in CSR activities.

This study evaluates the performance of green finance and investment scenarios in 15 carbon emitting countries, among which 7 are developed countries and 8 are developing countries. The principal component analysis is applied to form the global green financing (GF) and investment index, a composite indicator for assessing the multidimensional characteristics of GF and investment. The global green finance and investment index is developed to map the country’s overall GF and investing scenario. The indicator is developed on the basis of 30 variables that represent 11 quantitative factors. These factors are aggregated into four parameters: transparency, efficiency, efficacy and resilience. Transparency includes political stability and the development of the countries’ capital markets to adapt to the green transition. Efficiency consists of the performance of existing resources and regulatory conditions of the countries. Efficacy refers to the factors related to international engagement and the growth of specific financial instruments. Lastly, resilience includes factors that promote the adaptability of the countries towards a green economy and green financial system. It contains the regulatory structure of the country’s growth of macroeconomic variables. These variables represent social, economic, environmental and governance factors that influence the countries’ GF and investment scenario. The countries are ranked on the basis of the composite indicator score. The USA scored the highest rank, and India scored the least. In terms of developed countries, the USA has achieved the highest value, followed by Germany and in developing countries, China has scored the highest performance, followed by Mexico.

This chapter offers a preliminary investigation into the impact of the COVID-19 pandemic on consumer purchasing behaviour within the grocery retail industry and supports evidence that since the pandemic began at the end of 2019, there have been changes in the demands and behaviours of consumers (Donthu & Gustafsson, 2020). Previous research has reported that the pandemic resulted in retail consumers spending less and saving more (Jorda, Singh, & Taylor, 2020), as well as panic buying (Nazir, 2021), both of which initially contributed to the limited availability of goods. This preliminary study reports upon survey data collected from retail consumers and answers the question ‘What were the changes in consumer behaviour in the grocery sector as a result of the COVID-19 pandemic?’ Findings reveal that an increase in online shopping occurred more distinctly during the first of the UK’s lockdowns, which waned over time. Findings also reveal a lower shopping frequency, but higher shopping spends during lockdown, and that social distancing and discipline were key drivers of this behaviour change. Findings also reveal an intention to maintain a combination of new and old shopping behaviours and habits after lockdown, giving rise to the continuing importance of meeting consumers’ grocery needs online as well as in-store. This chapter further discusses the implications arising from the reported findings.

As cable and satellite industry undergoes transformation in the 21st century with the onslaught of innovation-driven changes, it is important to know which company is doing better and which company is falling behind. This study compares the relative performance of eight cable companies using three factors: operating expense for every dollar of operating revenue, earnings before interest, taxes, depreciation, and amortization, and return on assets. We also evaluate the performance of each firm against itself for the period 2010–2013 to see if they show improvement or deterioration in operating efficiency.
