Schelbergen, M. (author)The potential of utility-scale airborne wind energy (AWE) systems to contribute significantly to the energy transition hinges on their large-scale deployment, which depends on the cost-competitiveness and complementarity with conventional wind turbines. Central to the assessment of these metrics is understanding long-term energy production,...doctoral thesis 2024

Brandetti, L. (author)In urban areas, vertical-axis wind turbines (VAWTs) show promise due to their omnidirectional design, addressing challenges faced by traditional horizontal-axis turbines (HAWTs). Despite significant progress in urban VAWTs, extensive multidisciplinary research is needed to optimise their efficiency and use in such environments. <br/><br/>This...doctoral thesis 2024

van den Broek, M.J. (author)In the current state of model-based wind farm flow control, the implementation of yaw-based wake steering based on steady-state models has demonstrated potential for improving wind farm power production. However, for realistic, time-varying wind directions, the dynamics of wake propagation may impact the effectiveness of wake redirection. This...doctoral thesis 2024

Shi, W. (author)As a more convenient alternative to conductive charging technology, wireless charging is seen as a key technology drive for transportation electrification. In electric vehicle (EV) battery charging applications, wireless power is transferred through a magnetic link, so it is referred to as inductive power transfer (IPT). One advantage of IPT...doctoral thesis 2023

Mishra, V. (author)The world has seen industrial revolutions with advancements in manufacturing technologies. The advancements in Additive Manufacturing (AM) technologies will bring another revolution sooner rather than later. Nowadays, the Wire and Arc Additive Manufacturing (WAAM) process is already used to manufacture large-scale structures such as ship...doctoral thesis 2023

Bouter, P.A. (author)In recent years, the use of Artificial Intelligence (AI) has become prevalent in a large number of societally relevant, real-world problems, e.g., in the domains of engineering and health care. The field of Evolutionary Computation (EC) can be considered to be a sub-field of AI, concerning optimization using Evolutionary Algorithms (EAs), which...doctoral thesis 2023

Ekici, B. (author)Population growth and urbanisation trends bring many consequences related to the increase in global energy consumption, CO2 emissions and a decrease in arable land per person. High‑rises have been one of the inevitable buildings of metropoles to provide extra floor space since the early examples in the 19th century. Therefore, optimisation of...doctoral thesis 2022

Ebrahimi, Amin (author)The growing demand for manufactured products with complex geometries requiring advanced fusion-based manufacturing techniques emphasises the importance of process development and optimisation to reduce the risk of adverse outcomes, which is currently impeded with traditional approaches (trial and error experiments). Development, optimisation and...doctoral thesis 2022

van den Boomen, M. (author)Ageing infrastructures and shortage of financing induce the need for optimising public infrastructure replacements. From an economic perspective, classical net present value comparison is traditionally the method of choice to decide on investments and replacements. The current research observes that typical infrastructure related features make...doctoral thesis 2020

Wu, S. (author)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...doctoral thesis 2020

Marquez Calvo, O.O. (author)The exercise of solving engineering problems that require optimisation procedures can be seriously affected by uncertain variables, resulting in potential underperforming solutions. Although this is a well-known problem, important knowledge gaps are still to be addressed. For example, concepts of robustness largely differ from study to study,...doctoral thesis 2020

Dupuits, E.J.C. (author)Historically, people in flood-prone areas world-wide have (to a certain degree) accepted the risk of being flooded because of the benefits that flood-prone areas can provide; examples of such benefits are rich agricultural lands or trade advantages. Acceptance and benefits notwithstanding, people living in flood-prone areas have tried, and will...doctoral thesis 2019

Rotteveel, E. (author)This research focuses on identifying the most important stern shape aspects, with regard to resistance and propulsion power, of inland ships. Such information should help designers to determine which hull form aspect to adjust in case design requirements need them to do so. The information is obtained by firstly conducting a large series of CFD...doctoral thesis 2019

Hegberg, T. (author)In this dissertation, structural wind turbine blade layouts are presented that are suitable for 10MW and 20MW wind turbine blades. This has been accomplished by using a medium fidelity static aeroelastic model embedded in an optimisation framework. The structural solutions are the result of a stiffness optimisation where the blade mass is...doctoral thesis 2019

Duchateau, E.A.E. (author)Preliminary ship design (or early stage design in US terminology) is the very first step in designing a new ship. In this stage ship designers attempt to find an affordable balance of the future owner's (customer or operator) ambitions and operational needs. This balance is then translated into more tangible design requirements. However, the...doctoral thesis 2016
