Sihlovec, Oliver (author)Scientific problems are often concerned with optimization of control variables of complex systems, for instance hyperparameters of machine learning models. A popular solution for such intractable environments is Bayesian optimization. However, many implementations disregard dynamic evaluation costs associated with the optimization procedure....bachelor thesis 2023

Webbers, Jesse (author)Since the commercialisation of air travel, demand for air transport is increasing. Optimal system capacity utilisation at airports has therefore become crucial. As available resources such as land, buildings and human are scarce and airline tickets need to be financially affordable, airports optimise their system while maximising capacity within...master thesis 2023

Sigurðsson, Snorri Þór (author)Regular maintenance of civil engineering structures is essential for their safety. Current maintenance regimes involve periodic inspections at regular time intervals. In the time between inspections, there can be a critical development in the structural integrity of a structure, which can be expensive to repair or could even lead to structural...master thesis 2023

Vos, Kelly (author)This research is conducted in collaboration with the Sophia Children's Hospital (SCH). The hospital wants to provide their patients with more detailed information about when a patient is approximately scheduled to have a surgery. The first step is to create a model which optimises the operation room (OR) schedule and indicates when different...master thesis 2023

Kluwer, Thomas (author)Global warming has caused an increasing demand for renewable energy. Currently, 50% of the renewable energy is provided by wind and solar combined. However, these renewable energy sources are highly volatile. Wave energy converters can provide a stable renewable energy source. Previous research has contributed to understanding various combined...master thesis 2023

van Luijk, Nikki (author)The Flying V is a flying wing aircraft consisting of two pressurised passenger cabins placed in a V shape. Its longitudinal and lateral control is ensured via elevons and split flaps on the outboard wing, and rudders on the tip-mounted winglets. The goal of this study is to devise a design for the outboard wing of the Flying V through a...master 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

Bunnik, Floris (author)Automation in tomato greenhouses is lacking compared with some other crops. The efficiency and consistency of greenhouse operations can be boosted by implementing automation. Therefore, a new concept that facilitates the robotisation of crop-handling tasks is investigated. This concept combines the existing technology of a movable-gutter system...master thesis 2023

van Beekum, Karlijn (author)The operating rooms (OR) in hospitals is a complex system, with a high number of innovations every year. Therefore the healthcare professionals (HCPs) are required to choose between the several aspects and innovations for the OR. Decision-making requires a mutual vision (Littlejohn et al., 2017) and should be based on evidence (Turner et al.,...master thesis 2023
