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...

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...

Under the high requirement of ballast materials and the frequent maintenance of high-speed and heavy-haul railway, the maintenance cost and material consumption become an important problem. Several methods are used to increase the stability and service life of railway structure, also using recycled materials in ballast bed construction can be a...

Our routines play an important role in a wide range of social challenges such as climate change, disease outbreaks and coordinating staff and patients in a hospital. Studying these systems via agent-based simulations (ABS) enables researchers to gain insight into complex aspects of these challenges such as human interaction, learning,...

The field of epidemiology encompasses a broad class of spreading phenomena, ranging from the seasonal influenza and the dissemination of fake news on online social media to the spread of neural activity over a synaptic network. The propagation of viruses, fake news and neural activity relies on the contact between individuals, social media...

Particle Image Velocimetry (PIV) relies upon the introduction of particle tracers that scatter sufficient light and follow the flow accurately. The use of submillimetre helium-filled soap bubbles (HFSB) as flow tracers for PIV is investigated for the purpose of enabling velocity measurements in large-scale industrial wind tunnels. That soap...

Bird strike prevention in civil aviation has traditionally focused on the airport perimeter. Since the risk of especially damaging bird strikes outside the airport boundaries is rising, this PhD thesis researches the safety potential of operational bird strike prevention involving pilots and controllers. In such a concept, controllers would be...

Cities never function in isolation but as nodes in overarching systems characterised by flows of goods, people, and information. To fully understand the evolution of cities, a relational approach is needed, which investigates cities in relation to other cities and urban regions. While a significant part of urban system research has focused on...

Multi-fidelity optimization methods promise a high-fidelity optimum at a cost only slightly greater than a low-fidelity optimization. This promise is seldom achieved in practice, due to the requirement that low- and high-fidelity models correlate well. In this article, we propose an efficient bi-fidelity shape optimization method for...

This paper investigates the linkage between the acute impacts on apex marine mammals with polar cod responses to an oil spill. It proposes a Bayesian network-based model to link these direct and indirect effects on the apex marine mammals. The model predicts a recruitment collapse (for the scenarios considered), causing a higher risk of...

Mesh based methods such as the finite element method (FEM) are the most usually used techniques for analysing soil-structure interaction problems in geotechnical engineering. Nevertheless, standard FEM is unable to simulate large deformations and contact, hindering the realistic simulation of rotational, sliding, pull-out and overturning...

Innovations in biotechnology increasingly shape our societies and our planet. The stream of innovations that could be witnessed in the past few decades opens up new ways to do agriculture, to provide healthcare and to produce compounds and materials, amongst many other things. Many of these innovations rely on biological data. The ability to...

The energy-saving renovation of an existing building is a critical strategy in achieving a longterm energy goal in the Chinese context. However, in China, building energy renovation projects are subjected to quality failures resulting in energy wastage, a decrease in the energy efficiency of the project, an increase in project cost, and thus...

Presently, biomass pellets play a significant role in energy transition scenarios worldwide. Due to the lack of local supplies, many countries import their pellets from countries with enormous resources. For instance, in Europe, a big share of pellets is imported from the USA, Canada, and Asian countries. Pellets are normally transferred in bulk...

Breast cancer is the most common type of cancer for women and in developed countries it forms one of their largest threats. Many studies have shown that early detection by screening is important for achieving a successful treatment and reducing the mortality rate. Nowadaysmammography is the gold standard for breast cancer screening. However,...

Agriculture and horticulture depend heavily on human labor to perform tasks that are often dirty, hazardous, and highly repetitive. One reason for the lack of automation of these tasks is the absence of suitable robotic handling equipment. Rigid robotic manipulators are typically incapable of performing dexterous manipulation tasks such as...

The interaction of an airfoil with incident turbulence is an important source of aerodynamic noise in numerous applications, such as turbofan engines, cooling systems for automotive and construction industries, high-lift devices on aircraft wings, and landing gear systems. In these instances, turbulence is generally produced by elements that are...

Thiamine diphosphate dependent enzymes are excellent catalysts for the asymmetric synthesis of the α-hydroxyketone (acyloin) structural motif, which is found in many pharmaceuticals and fine chemicals. In chapter 2, variants of transketolase from Saccharomyces cerevisiae were screened for the conversion of aliphatic aldehydes with...
