The objective of this thesis is to enhance understanding of the behaviour of a flexible dolphin and its interaction with the surrounding soil in order to determine the optimal embedded depth. A comprehensive field test is conducted to gain deeper insights into the behaviour of the flexible dolphin and the soil surrounding the pile. The test...

Distributed databases often struggle to fulfill their transactional isolation guarantees due to sharding and replication. As a result, the problem of checking isolation levels is consistently receiving attention from academia and industries. Transactional dependency graphs form a useful abstraction to analyze the transactions’ dependencies and...

The reliability of power semiconductor devices is an important feature when designing converter, since the semiconductors are prone to failure and a weak link in the system. Power semiconductor devices are susceptible to thermo-mechanical stresses, and should be investigated to make reliable semiconductors. The power losses inside the device...

Writing unit tests is a crucial task in the software development lifecycle, ensuring the correctness of the software developed. Due to its time-consuming and laborious nature, it is, however, often neglected by software engineers. Numerous automatic test generation tools have been devised to ease unit testing efforts, but these test generation...

Fault injection has been a long-standing technique for testing software. Injecting faults into a system, either in production or development environments, offers unique opportunities to discover bugs that are difficult to reproduce using conventional testing methods. However, it is widely considered to have a high implementation threshold. Due...

Every time one counts the number of occurrences of a pair of values for two categorical variables, one obtains a contingency table. These tables are one of the simplest representations of data in order to statistically test for the presence of some association between the two variables under consideration. Although naturally occurring in so many...

The energy market is growing and noise regulations for offshore foundation pile installation grow stricter. New initiatives arise to comply with the ongoing developments in the field, such as the BLUE Piling Technology under development by IQIP. Its features are presented as reduced underwater noise levels during installation, which is attibuted...

The wind turbine wake is a downstream region of kinetic energy and velocity deficit, higher turbulence and has a complex helical vortex structure. The wind turbine wake’s stability depends mainly on the ambient turbulence and the wind turbine tip- speed ratio. Researchers have developed several wake control techniques to mitigate this issue,...

Delamination is a significant failure mode that has been the subject of extensive research in laminated structures. The interface in assembly structures often represents the susceptibly weak link and necessitates careful consideration to guarantee structural stability. It is of utmost significance to understand the behaviour of the delamination...

Previous research into floating offshore wind turbines consistently shows some manner of discrepancy between numerical and experimental simulations when it comes to low frequency forces and motions. A part of solving this issue is the generation of accurate data for the calibration and validation of the numerical models, needed because of the...

Aluminium alloy AA2024-T3 is a lightweight and damage tolerant material, and is therefore often used in aerospace applications. However, this alloy is difficult to weld using conventional fusion welding techniques due to defects caused by the meld pool.<br/> <br/>Friction stir welding (FSW) was developed by The Welding Institute (TWI) in 1991 in...

Coral reefs are considered to be a crucial ecosystem and form of natural coastal protection. They owe their effectiveness to their high structural complexity. This complexity, which positively influences aspects like species richness, coral recovery, live coral cover, and coastal protection, is often quantified using parameters such as porosity...

Background: For rigorous software testing, integration and end-to-end tests are essential to ensure the expected behavior of multiple interacting components of the system. When software is subjected to integration or end-to-end tests, it is often unfeasible to test every code change individually, as the runtime of these tests is usually...

Interest in driving simulators has risen due to new technologies that better resemble real-world driving and the cost reduction of driving simulator development. In recent years, safety researchers commonly use driving simulators to examine complex driving behaviors in a controlled and safe environment. However, the question remains whether or...

Stability assessment for dikes and dike reinforcement requires insight in soil strength behaviour. The required parameters for this assessment are typically obtained from conventional laboratory tests. These conventional tests are not performed under conditions found in the field. For example, a dike section resembles to plane strain conditions....

One of the biggest challenges of the century is the fight against global warming. In all sectors people are doing their best to reduce their carbon footprints and their impact on the environment. In the energy sector this is done by making use of renewable energy sources (RES), such as wind turbines, instead of fossil fuels. This transition to...

Ceramic matrix composites (CMCs) are advanced materials that consist of a ceramic matrix reinforced with a high-strength, high-stiffness material, such as carbon fibers. They offer excellent thermal and chemical stability while exhibiting low weight and exceptional mechanical properties. A novel CMC material is the C/C-SiC produced with 2/2...

Given the desire to construct more structures using sustainable building materials, demand for wood and other bio-based building materials has risen dramatically over the decade. While timber itself is a carbon-neutral material and can sometimes even be carbon-negative, reusing wooden structural members made that have been in service for several...

Strain hardening cementitious composites (SHCC) can be used to reduce the amount of reinforcement needed to control crack widths. SHCC has a strain hardening behaviour with dense micro-cracking, which makes it more ductile compared to conventional concrete. Conventional concrete can be used in the non-critical locations. An interface is formed...

The integration of large-scale battery storage systems can aid the transition to renewable energy and stabilize energy systems for optimization. However, batteries can be cost-prohibitive and unprofitable, highlighting the need for a more comprehensive understanding and modelling of battery degradation. Battery degradation prediction models play...
