Sophus Lie (1842-1899) known as the founder of the theory of transformation groups, originally aimed to study solutions of differential equations via their symmetries. Over the decades this theory has evolved into the theory of Lie groups. These Lie groups are of an analytic and geometric nature, but Sophus Lie's principal discovery was that...

Ocean waves being considered to have huge potential on providing renewable energy resources. While significant research and application of wave energy converters have been conducted in many seas, exploration on low-energy seas is still an ongoing endeavour. In this study, a point absorber array is being studied in the scenario of implementing at...

Taiwanese landscape has dramatically changed since 2018, when the Energy Transition White Paper was published. Due to the land limitation, the Taiwanese government has focused on the multifunctional use of land to create renewable energy and maintain the original activities on the ground at the same time, especially on agricultural lands....

This thesis explores spatial strategies for achieving sustainable industry transition in the dispersed urbanised areas of the Greater Bay Area (GBA) in China. Since 1978, urbanisation in the GBA has accelerated, significantly expanding beyond metropolitan regions. These dispersed areas, described as the Desakota by Terry McGee, encompass a...

Machine learning can be effectively applied in control loops to robustly make optimal control decisions. There is increasing interest in using spiking neural networks (SNNs) as the apparatus for machine learning in control engineering, because SNNs can potentially offer high energy efficiency and new SNN-enabling neuromorphic hardwares are being...

Membrane technology is widely used as an effective water treatment or pretreatment technology, especially in the filtration of oil-in-water (O/W) emulsions. Ceramic membranes have shown excellent performance in this regard. However, due to the complex composition of real wastewater, laboratory studies are limited to the filtration of simulated O...

In recent years, carbon dioxide and other greenhouse gases have been emitted on a large scale, leading to global warming, rising of sea levels, and causing many ecological problems. The use of fossil fuels is the chief source of large-scale emissions of CO2, but the reliability and economy of fossil fuels make it difficult for other energy...

The livestock sector accounts for 14-15% of the global greenhouse gas emissions. Furthermore, the current meat consumption patterns are associated with multiple health risks and are unsustainable in the long term. Therefore, the shift to a more plant-based diet and reduced animal-source intake is desired from a societal perspective. One attempt...

Relative localization (RL) is essential for the successful operation of micro air vehicle (MAV) swarms. Achieving accurate 3-D RL in infrastructure-free and GPS-denied environments with only distance information is a challenging problem that has not been satisfactorily solved. In this work, based on the range-based peer-to-peer RL using the...

Fatigue is typically a governing limit state for maritime structures, and weld joints are the most critical locations. Various fatigue damage criteria have been developed involving either an intact or cracked geometry parameter, incorporating local or global information. In this thesis, the effective notch stress based total life fatigue damage...

In this 3D fracture-based topology optimization framework, the author extended the 2D framework on tailoring fracture resistance for brittle materials (Zhang et al., 2022) to 3D. In the optimization, the topology is described by radial basis functions interpolated level set function, and the problem is solved by the Interface-enriched...

Soft robots are made of compliant materials, which increase their flexibility but also presents modeling challenges. The difficulty mainly comes from material nonlinearity, infinite degrees of freedom, uncertain parameters, and complex calculations. This project uses physics-inspired neural networks to solve the last two problems. Based on the...

The performance of multiple AMoD operators under congestion pricing strategies remains unexplored. We propose two congestion pricing strategies: Link-based congestion pricing strategy and Delay-based congestion pricing strategy to regulate AMoD services. We aim to demonstrate the effectiveness of such strategies using an agent-based modeling...

Starting from a port, Marseille was born as the result of improvisation and spontaneous architectures rather than urban planning. Same things happened in the architecture scale. architects are not the only doers of architecture. Long after the building has been made the non-architects continuously do architecture. When non-architects occupy...

This article presents a novel wide operational range reconfigurable regulating rectifier for wireless power transfer. The proposed 1X/2X/3X rectifier achieves wide range voltage regulation without global loop control to minimize the area occupation. Compared with previous work, more working modes and greater magnification allow the proposed...

Reinforcement learning (RL) has grown tremendously over one and a half decades and is increasingly emerging in many real-life applications. However, the application of RL is still limited due to its low training efficiencies and surplus training cost. The sampling and computation complexity normally depends on the size of the state space and...
