Offshore wind farms suffer substantial energy losses due to the interference of wind turbine wakes, with estimates indicating losses of approximately 10%. This thesis aims to advance the state of the art of wind farm flow control techniques for maximizing wind farm power performance. Wind farm flow control can be divided into three categories:...

Machine learning (ML) is an artificial intelligence technology that has a great potential for being adopted in various sectors of activities. Yet, it is now also increasingly recognized as a hazardous technology. Failures in the outputs of an ML system might cause physical or social harms. Besides, the development and deployment of an ML system...

Data sharing through data marketplaces, which rely on a Trusted Third Party (TTP), can benefit businesses and society. However, many companies and consumers are increasingly reluctant to share data due to mounting concerns over data control and privacy. Emerging privacy-enhancing technologies (PETs) like Multi-Party Computation (MPC), which...

Europe’s offshore wind capacity is expected to reach 450 GW by 2050, meeting 30% of Europe’s electricity demand. With the increase of installed capacity, the costs invested in O&M will also increase significantly considering O&M cost is one of the biggest contributors to life cycle costs. The improvement of O&M management for...

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...

Although business model innovation (BMI) can create a firm's competitive advantage and enhance its performance, many small and medium-sized enterprises (SMEs) fail to obtain the expected outcomes when innovating their business model. BMI leads to irreversible fundamental changes in key components of a company's business model, which means it...

The aim of this PhD project was to explore the multi-level interplay between the inter-organizational structures and interpersonal relations in building project organizations. In the first two studies, quantitative approaches were used to validate assumptions about how inter-organizational structures are shaped by actors and how interpersonal...

Transport networks are operated under a pre-designed plan to carry out the trans- portation tasks. Perturbations can inevitably arise exogenously or endogenously, and cause disturbances to the transit of passengers or the delivery of freights. A transitional plan is needed to deal with the perturbations and accomplish the trans- port tasks. The...

Autonomous vehicles (AVs) have been heralded as the key to unlock a shared mobility future where transportation is more efficient, convenient, and cheaper. However, the AV utopia can only come to fruition if the majority of users trust that autonomous mobility-on-demand (AMoD) systems are on a par with owning a vehicle in terms of service...

Frederik, J.A. (author)
The dissertation discusses different wind turbine control strategies that use pitch actuation to decrease the Levelized Cost of Energy (LCoE) of wind farms. This is achieved by either mitigating the loads experienced by individual turbines, or by enhancing wake mixing in turbines located within a wind farm. The latter strategy exploits the fact...

Heat transfer by the motion of fluids, referred to as convective heat transfer, is ubiquitous. Convective heat transfer in enclosures packed with solid obstacles, is of great importance in various engineering and real-life applications, such as in blast furnaces, refrigeration devices, distribution transformers, nuclear waste disposal, energy...

In the chain of steel production, the blast furnace converts iron ore into liquid iron. The hearth of the blast furnace, where the liquid metal is collected and tapped off, is filled with relatively large coke particles (D ~ 20 – 100 mm). The meandering flow of hot liquid metal in the coarse-grained porous medium in the hearth causes erosion of...

Elzas, A. (author)
Multiphase alloys such as advanced high strength steels show limited ductility due to interface decohesion at internal boundaries. This interface decohesion is caused by dislocations that pile-up at interfaces in the material, where they cause a stress concentration. This stress concentration in turn can lead to interface decohesion, resulting...

Pfitzenmaier, L. (author)
Clouds are a prominent part of the Earth hydrological cycle. In the mid latitudes, the ice phase of clouds is highly involved in the formation of precipitation. The ice particles in the clouds fall to earth either as snow flakes, in the winter month, or melting crystals that become rain drops. An efficient growth process is the interaction of...

Gunyol, O. (author)
The current understanding of the transport phenomena involved in the operation of industrial fermenters is not sufficient. This is reflected by the limitations seen in their design and operation. A better insight in the local processes taking place (hydrodynamics, gas dispersion, mixing, microbial kinetics) is required to be able to make a step...

Estuaries are important ecosystems accommodating a large variety of living species. Estuaries are also important to people by their demand of freshwater for drinking, irrigation, and industry. Due to natural changes and human activities, the estuarine water quality, influenced by both salinity and turbidity (the cloudiness or haziness of water),...

Fibre-metal laminates (FMLs) have been studied intensively for the past three decades because of their enhanced fatigue properties compared to monolithic metals. Most of these studies have focused on the fatigue damage under in-axis loading. These studies led to the application of FMLs in the aircraft structure in the early 21st century. However...

The subject of this thesis is the study of maximal L<sup>p</sup>-regularity of the Cauchy problem u'(t)+A(t)u(t)=f(t), t∈ (0,T), u(0)=x. <br/>We assume (A(t))_{t∈ (0,T)} to be a family of closed operators on a Banach space X<sub>0</sub>, with constant domain D(A(t))=X<sub>1</sub> for every t∈ (0,T). Maximal L<sup>p</sup>-regularity means that...
