In this work, we present the results of a preliminary uncertainty quantification and sensitivity analysis study of the Molten Salt Fast Reactor (MSFR) behavior at steady-state performed by applying a non-intrusive Polynomial Chaos Expansion (PCE) approach. An in-house high-fidelity multi-physics simulation tool is used as reactor reference...

This study proposes a framework to analyze accelerated degradation testing (ADT) data in the presence of inspection effects. Motivated by a real dataset from the electric industry, we study two types of effects induced by inspections. After each inspection, the system degradation level instantaneously reduces by a random value. Meanwhile, the...

In the past decade the role of wooden fences, containing brushwood and branches, in efforts to restoring mangroves has been recognized since a vast reduction of mangroves occurred along the Mekong deltaic coast. This study aims to better understand the hydrodynamic performance related to the possible mechanism of wave reduction and the influence...

Residue amplification plays a key role in determining the energy efficiency, area and performance of high-speed pipelined ADCs. At its core, a residue amplifier simply consists of four transistors that transfer a differential input voltage to a capacitive load with the desired gain. However, in order to ensure gain accuracy over PVT, the core...

MAX phases are a family of ternary carbide or nitride ceramics possessing a layered crystal structure and, due to their chemical bonds having a mixed covalent-ionic-metallic nature, have unique properties combining those of metals and ceramics. In this review, the formation mechanisms of MAX phases from elemental and compound powders are...

Modern aircraft have thousands of parts, systems, and components that need to be recurrently inspected or replaced. To keep the fleet airworthy, maintenance planners have to schedule the maintenance checks for each aircraft and the associated tasks. In practice, these two complex problems are solved following the experience of planners,...

The ability to model irregular data and the interactions between them have<br/>extended the traditional signal processing tools to the graph domain. Under<br/>these circumstances, the emergence of graph signal processing has offered a<br/>brand new framework for dealing with complex data. In particular, the graph<br/>Fourier transform (GFT) lets...

The Kirkwood–Buff (KB) theory is one of the most rigorous solution theories that<br/>connects molecular structure to macroscopic behaviour. The key quantity, the so–called KB Kirkwood–Buff Integrals (KBIs), are defined either in terms of fluctuations in the number of molecules or integrals over radial distribution functions over open subvolumes....

The prospect of stricter national and international emission standards for the shipping industry are a driving force in the search for alternative shipping fuels, such as liquefied natural gas (LNG). However, new challenges arise with the widespread use of LNG. For example, there is a desire to use LNG cargo containment...

The ongoing energy transition results on the one hand in a proliferation of power electronics interfaced devices and on the other hand in a decreasing availability of conventional synchronous generation. These developments pose important challenges for transmission system operators to operate a low inertia power system. As part of my research I...

People are engaged in a variety of activities through space every day. The choice of type and location of activities is known as human spatial behavior. Urban decision makers need to understand how land use and transportation systems can shape human spatial behavior in order to design better systems. In the past, they have collected mobility...

Molecular imaging aims for the visualisation, characterisation, and quantification of biological processes in humans and other living systems at the molecular and cellular level. For today’s patient care, molecular imaging allows for (early) detection and characterisation of disease, efficient planning and assessment of treatments, and...

This thesis describes a series of experiments, algorithms, and methodology development for implementing Prognostics and Health Management (PHM) in the field of automotive electronics. Furthermore, a new PHM framework is proposed explicitly tailored for the harsh environment electronics. In addition, the entire apparatus is built, such as the...

According to Person-Centred Care, as far as possible, people with dementia should be cared for in a way that takes into account their personality, life experiences and preferences. Personalisation is hence the core of Person-Centred Care, yet the approaches, recommendations and tools are lacking for this purpose. Therefore, the author...

An urban plan contains a set of agreements from all stakeholders that may directly impact livelihood. However, many cities show a ‘plan and forget’ behavior by not monitoring and evaluating their urban plans. While local citizens are often excluded after the urban plan is enacted. Gibbs (2016) warned of the risk of this behavior by saying, ...

This dissertation's ultimate goal is to provide solutions to two problems that the promising data assimilation method, called the Particle Filter, has when applied to high dimensional non-linear models, such as those often used in hydrological research and forecasting. Two local particle filters have been proposed to overcome three major issues....

Open recirculating cooling systems have been vital elements in industry since the early 20th century. Their purpose is to release excess heat from processes through water evaporation so that production can be carried out at optimal temperature. With the global development of industrial activities such as manufacturing, electricity and chemical...

Climate change, combined with the rapid and often unplanned urbanisation trends, is associated with a rising trend in the frequency and severity of disasters triggered by natural hazards. Among the weather-related disasters, floods and storms (i.e. hurricanes) account for the costliest and deadliest in the last decades. The situation is of...
