Cardiovascular disease is currently one of the biggest threats to health. Specific types of cardiovascular disease include, but are not limited to, coronary artery disease, cardiac valve disorders, or peripheral arterial disease. The current gold standard for managing these conditions incorporates the use of catheters and guidewires for...

Catalysts are often used in challenging chemical reactions to accelerate the reaction rate, increase reaction efficiency, reduce energy consumption, and minimise waste production. In biocatalysis, enzymes or whole cells are used as catalysts with the advantage of reactivity, selectivity and mild reaction condition over chemocatalysis. Nowadays,...

Supplementary cementitious materials (SCMs), like fly ash (FA) and blast furnace slag (BFS), are widely used in concrete to partially replace the cement clinker in the production of blended cement or directly replace part of Ordinary Portland cement (OPC) in the concrete. No matter how the SCMs are introduced, they can reduce the cost of...

For almost three decades, side-channel analysis has represented a realistic and severe threat to embedded devices' security. As a well-known and influential class of implementation attacks, side-channel analysis has been applied against cryptographic implementations, processors, communication systems, and, more recently, machine learning models....

Recently, the implementation of prefabricated housing (PH) has become prevalent in China to achieve sustainability while ensuring green construction, innovative products, and higher quality. However, numerous challenges arise, such as the overrun costs, inexperienced workers, and the inefficient management process. High transaction costs (TCs)...

As STT-MRAM mass production and deployment in industry is around the corner, high-quality yet cost-efficient manufacturing test solutions are crucial to ensure the required quality of products being shipped to end customers. This dissertation focuses on STT-MRAM testing, covering three abstraction levels: manufacturing defects, fault models, and...

Seismic data acquisition is a trade-off between cost and data quality subject to operational constraints. Due to budget limitations, 3D seismic acquisition usually does not have a dense spatial sampling in all dimensions. This causes artefacts in the processed images, velocity models, or other physical properties. However, we rely on, for...

Occasionally sporadic defects in high voltage cable insulation may escape from detection by commissioning or maintenance tests. Usually these tiny defects will not initiate significant partial discharges or cause breakdown in the cable insulation system under normal AC operating condition and normal transient situations. However, nowadays more...

The European Union and the United States are proposing to bring in more strict flight vehicle emission criteria in their reports of the high‐level groups on aviation research, i.e. EU Flightpath 2050 and US Destination 2025. More fuel‐efficient aircraft must be developed to achieve this target. Moreover, the increasingly competitive aviation...

The microstructural aspects of rolling contact fatigue in rails were studied. The rail track is a critical component of the railway system and its long-term performance contributes crucially to the sustainable development of the railway system. The increasing demands of trains with a higher speed/capacity impose more severe load conditions on...

Dynamic analysis of large-size finite element models has been commonly applied by mechanical engineers to simulate the dynamic behavior of complex structures. The ever-increasing demand for both detailed and accurate simulation of complex structures forces mechanical engineers to pursue a balance between two conflicting goals during the...

The Aerosol Optical Depth (AOD), a measure of the scattering and absorption of light by aerosols, has been extensively used for scientific research such as monitoring air quality near the surface due to fine particles aggregated, aerosol radiative forcing (cooling effect against the warming effect by carbon dioxide CO2 ), aerosol long-term trend...

One of the most basic features that pervade biology is the existence of boundaries that separate living cells from their outer environments. Molecules responsible for the internal organization of a living cell must adapt to its boundaries, as the cell grows, divides, and changes in shape and size. In this thesis, we aim to understand how...

This research explores the possibility of a large-scale bulk terminal in West Europe dedicated to handle solid and liquid biomass materials. Various issues regarding the conceptual design of such a terminal have been investigated and demonstrated in this research: the potential biomass materials that will be the major international trade flows...

Conventional TiO2 based photocatalysts oxidize NOx to nitrates which do not automatically desorb and have to be washed away from the catalyst surface. To avoid this, the research described in this thesis aims to design new photocatalysts that can photo-reduce NO into N2 and O2. Previous efforts in the literature have shown that catalysts...

In this thesis, a referenced based scaling approach and its parameter extraction for the bipolar transistor model Mextram is proposed. It is mainly based on the physical properties of the Mextram parameters, which scale with the junction temperature and geometry of the bipolar transistor. The scalable electrical parameter in the scaling rules is...
