Questions are critical for information-seeking and learning. Automatic Question Generation (AQG) involves the subjects of Information Retrieval (IR) and Natural Language Processing (NLP), and focuses on automatically creating questions for various applications, subjects which have been studied for decades. In this thesis, we study how to create...

Shape memory alloys (SMAs), such as nickel-titanium (NiTi) alloys or Nitinol, possess remarkable properties, including superelasticity and shape memory effects, which are attributed to the reversible martensitic transformation. However, traditional manufacturing of NiTi SMAs is challenging due to its high ductility and reactivity, which limits...

Copulas are important models that allow to capture the dependence among variables. There are many types of bivariate parametric copula families, which allow to model data sets with different properties: symmetric and asymmetric dependence, upper (lower) tail dependence. In higher dimensions popular families of copulas, e.g., Gaussian, Student-t...

Planning safe motions for multi-robot systems is crucial for deploying them in real-world applications such as target tracking, environmental monitoring, and multi-view cinematography. Traditional approaches mainly solve the multi-robot motion planning problem in a deterministic manner, where the robot states and system models are perfectly...

Estuarine sediment dynamics involves estuarine hydrodynamics, sediment transport, and morphology, and strongly influence ecosystem dynamics and sustainability. In the current geological epoch, referred to as the Anthropocene, human activities are exerting increasing impacts on the environment on all scales, changing hydrodynamics, sediment...

In past decades, small spacecraft have raised worldwide interest for their low cost and short development time. In general, three reaction wheels are needed for three-axis attitude control of general satellites. However, for small spacecraft where both volume and power budgets are limited, employing three wheels is a challenge. Therefore,...

In recent years, the accuracy of Deep Neural Networks (DNNs) has improved significantly because of three main factors: the availability of massive amounts training data, the introduction of powerful low-cost computational resources, and the development of complex deep learning models. The cloud can provide powerful computational resources to...

The main goal of this thesis is to investigate, improve and extend the applicability of mutation testing. To seek the potential directions of how to improve and extend the applicability of mutation testing, we have started with a systematic literature review on the current state of how mutation testing is applied. The results from the systematic...

Railway systems are vulnerable to unexpected disruptions, which usually result in track blockages for a few hours. In practice, disruptions are handled manually and the resulting impact to passengers is rarely considered. To enable disruption management more efficiently, operator-friendly and passenger-friendly, this thesis develops mathematical...

Experience prediction is one key component in today’s multimedia delivery. Knowing user’s viewing experience allows online video service providers (e.g., Netflix, YouTube) to create value for their customers by providing personalized content and service. However, individual experience prediction is a challenging problem since viewing experience ...

Tidal flats provide essential ecosystem services (e.g. coastal protection and function as habitats sustaining coastal food webs). They are also under pressure due to climate change and human interventions. To investigate the sediment dynamic processes on tidal flats for a better understanding of the morphological development, in situ...

Harness 3D routing is one of the most challenging steps in the design of aircraft Electrical Wiring Interconnection System (EWIS), due to the intrinsic complexity of the EWIS, the increasing number of applying design constraints, and its dependency on the design changes of the airframe and installed systems. The current routing process employed...

In this thesis, I have shown that the quality of synthetic graphene can be as high as mechanically exfoliated graphene if we can get rid of the wrinkles. Any defects, impurities and grain boundaries will induce scattering, preventing ballistic transport. The experiment described in chapter 4 was the first to demonstrate ballistic transport in...

Aerospace aluminium alloys (7xxx and 2xxx series Al alloy) is one of the important Al alloys in our life. The recycling of aerospace Al alloy plays a significant role in sustainable development of Al industry. The fibre reinforced metal laminates GLARE including 67 wt.% 2024 Al alloy was used as upper fuselage in Airbus A380, but the solution...

Numerous flood disasters occur every year worldwide, mostly resulting from failure of dikes, some with catastrophic outcomes. Examples are the dike failures along the Yangtze River in China in 1931 due to heavy rainstorms and those in the Netherlands in 1953 due to a storm surge at the North Sea. Both floods induced many deaths and enormous...

In this dissertation we study the surface temperature excess in heterogeneous catalysis. For heterogeneous reactions, such as gas-solid catalytic reactions, the reactions take place at the interfaces between the two phases: the gas and the solid catalyst. Large amount of reaction heats are released at the interface for strong exothermic...
