Currently active suspension system is more applicable than passive for improving the suspension performance, ensuring the stability and passenger safety in modern automotive suspension system. However, high energy consumption is one of the main disadvantages of implementing this system in real applications. In this paper, the energy consumption of electromagnetic actuators used for an active suspension system controlled by proportional-integral-derivative (PID), fuzzy adaptive PID, and neuron adaptive PID are investigated through simulation studies. Based on the energy consumption and the performance analysis, it has found that it is potential to develop a vibration energy recovery system to achieve the energy balance requirement in active suspension systems.

Localisation of humanitarian aid has emerged as a major issue after the World Humanitarian Summit in 2016 which emphasised the importance of locally-led response as a corrective to power imbalances in the humanitarian system. However, the practical complexities of localised humanitarian aid are yet to be fully discussed. This paper aims to examine the concept of localisation in humanitarian aid through a case study of a local non-governmental organisation, the Cambodian Children's Trust (CCT), in Cambodia. Drawing on the framework of localisation proposed by Baguios et al., (2021), we analyse the application of localisation of child protection programs run by CCT. We provide a holistic understanding of how localisation is conducted in practice, and the impacts it has on the wider humanitarian sector. Our study illustrates that power can be effectively developed to local entities and localisation with empowerment could be achieved despite highly challenging conditions.

Points out that sustainability as such does not provide a clearcut guide to policy. First one has to decide what is to be sustained. If this is agreed, it must be in an operational from. However, difficulties may still emerge since opinions may differ about how to achieve. This is illustrated by differences in the views of economists about how sustainable development is to be achieved. Orthodox economists stress the importance of the accumulation of man-made capital to achieve this end whereas neo-Malthusians stress the importance of conserving natural resource and environmental capital. Both take an anthropocentric point of view. For political reasons the neo-Malthusian has had little support but it may eventually turn out to be correct. Economics is concerned with reducing economic scarcity and economists have traditionally suggested four main ways of doing this of which economic growth is one. However, neo-Malthusian economists believe that this may not be a sustainable strategy – it may result in future poverty. It should be noted that economic systems are embedded in social and natural systems and depend on these. Economic sustainability depends on the sustainability of these other systems. So from this point of view, it is just one of several bottom lines. Values must be considered in relation to sustainability. Economics is completely anthropocentric in its approach. Therefore, economic approaches to conservation and sustainability can be at odds with the values of deep ecologists or those willing to accord rights to other sentient beings or ecosystems independent of human wishes, or those who want to make use of value judgments other than those based on the measuring rod of money. Consequently economics evaluation is sometimes ineffective in resolving social conflict, including conflict about what should be sustained. As a rule economics alone should not be the final arbiter of social decisions. It is a part (often an important part) of the social evaluation process but not the bottom line, or just one of many lines.

This doctoral thesis focuses on tourism recovery, sustainability and future development under the influence of global industry crisis. Part I provides the introduction. Part II introduces the conceptual framework of three published theoretical papers. The first paper focuses on bibliometric studies of tourism and COVID-19 topics. The current state of the art reveals interdisciplinary research interests on crisis management, tourism sustainability and stakeholder collaborations. It also identifies underexplored topics on the social, environmental, cultural and governance dimensions of sustainable tourism and stresses the function of technology and innovation in helping sustainable governance and protocols. The second paper focuses on the thematic analysis of tourism sustainability and COVID-19 and highlights new growth potentials in high technologies utilization, strategic planning and management. The third paper focuses on the thematic analysis of China’s tourism recovery and resilience strategies. Measures related to tourism industrial reemployment, digitalization, nature, cultural heritages and dark tourism became important factors in the future development of China’s tourism. Part III introduces two empirical studies, with the fourth paper – panel data analysis upon cross-sectional sustainable performances of tourism and hospitality companies, in discovering their relationships with corporate financial performances when moderated by global industrial crises. It contributes to advancing our comprehension of the determinants influencing sustainability in the hospitality sector, with a nuanced understanding of how global industrial crises moderate these dynamics. The fifth paper was an empirical study on tourism sustainability and innovation – in finding the relationships between environmental innovation and tourism sustainable performances, financial performances, and how the relationships would be influenced under the global crisis lens. It has highlighted environmental innovation as a potential worthy investment and green transition opportunity, in dealing with global climate change, innovative capabilities in environmental management, and fulfillment of stakeholder social commitment. Part IV demonstrates the conclusions, implications, limitations and future research.

Green ammonia is gaining momentum as a globally significant technology for deep decarbonisation. In this thesis, several models are developed across chemical, techno-economic, and energy system modelling disciplines to explore the future role of green ammonia. First, standalone models of production (i.e., power-to-ammonia) and re-electrification (i.e., ammonia-to-power) are developed and compared to competing technologies. Second, these models are integrated into a planning and dispatch energy system model (ESM) of India to 2050. The ESM has several novel additions including the sector coupling of hydrogen and ammonia, multiple years of granular weather data, and learning-curve-based technology cost forecasts. India is chosen as an ideal case study given its globally unmatched demand growth in all three relevant sectors: electricity, green hydrogen, and green ammonia. The projected electricity demands for green hydrogen and ammonia production account for 25% of the total Indian electricity demand in 2050, underscoring the transformational potential that green hydrogen and ammonia sector coupling can have on the Indian energy system. The results of the state-of-the-art ESM highlight synergistic effects of hydrogen and ammonia sector coupling with the power system. The least-cost system employs seasonal green ammonia production paired with up to 40 million tonnes (i.e., 200 TWh) of ammonia storage, as well as some re-electrification via gas turbines. Sector coupling reduces system curtailment, addresses challenges of long-duration storage, and improves system resilience to interannual weather variations. While India is a crucial case study from a global decarbonisation perspective, the methodology and findings are generally applicable, and it is the aim of this work to motivate and accelerate the wider research community into considering the potential impacts of green ammonia sector coupling on electricity grid design. Finally, this work highlights strategic technology development direction for ammonia producers and gas turbine manufacturers, as well as implications for policymakers.
