Manila, R.M. (author), Srinivasan, Kandadai (author), Dutta, Pradip (author)Adsorption chiller dynamics and its effect on the performance are greatly influenced by the adsorbent particle size because they govern both the micro (intra-particle) and macro (inter-particle) heat and mass transfer resistances within the adsorber bed. The net effect of adsorbent particle size and shape on the overall cooling system...journal article 2024

Teertstra, Bouke (author)The company H2 Marine Solutions has designed a zero-emission hydrogen powered boat. This boat is compared to its fossil fuel counterpart more than twice as heavy. The reason for this is that the system components that are used in the hybrid powertrain of the hydrogen powered boat are heavier. The main question of this research is: How can we...master thesis 2023

Huang, Yuwei (author)Slow sand filters (SSFs) are essential for ensuring microbial quality and biological stability of drinking water in the Netherlands. However, gaps exist in understanding of removal processes of dissolved organic carbon (DOC) and ammonium and the effects of grain size, loading rate, and backwashing on removal in SSFs.<br/>Four lab-scale SSF...master thesis 2023

Brown, Reiny (author)In cycling, the presence of drag reduction from drafting, when multiple cyclists ride in tandem, is a considerable area of performance enhancement for a cycling team and the customisation of this tandem group has the potential of maximising the drag reduction for the entire group or a specific cyclist. The flow interactions between two tandem...master thesis 2023

Li, M. (author)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...doctoral thesis 2023

Hummel, Jesse (author)Power output during flight operation of multi-megawatt airborne wind energy systems is substantially affected by the mass of the airborne subsystem, resulting in power fluctuations. In this paper, an approach to control the tether force using the airborne subsystem is presented that improves the quality of the power output. This kite tether...master thesis 2023

de Ruijter, Marije (author)At the moment there is an increasing shortage of raw materials. The approach of a circular economy can be used to reduce the need for new materials. This includes design for adaptability. During interviews and a literature review, methods that are used to increase adaptability were determined, including oversizing elements and demountable...master thesis 2023

van IJzendoorn, Christa (author)Coastal dune systems provide valuable functions that are threatened by human activity and climate change. Preserving and strengthening coastal dunes through coastal management and the implementation of interventions require accurate predictions of coastal dune development. The development of coastal dunes is driven by complex interactions...doctoral thesis 2023

Bacani, Jasmine (author)Globalized universities located in small cities are expanding at a rate beyond the spatial capacity of its host city. The resulting presence of student housing in these cities known as ‘studentification’, have cascading social, cultural, economic, and spatial impacts that lead to, in particular, a lack of co-existence and tolerance between the...master thesis 2023

WU, KANGJIE (author)The research on sustainable energy is growing, among which, wind energy catching growing attention and the potential has been supported by more and more countries. Compared with onshore wind farms, offshore wind farms have more advantages including the abundant wind resource at the offshore location and more possible construction areas. While...master thesis 2023

Frijns, Jesper (author)Laser satellite communications for ground-to-ground and ground-to space links is influenced by atmospheric turbulence. Typically, theoretical models are used to predict link performance and the influence of the atmosphere on variables such as beam wander, spot size and scintillation at the receiver. These variables are used as input for system...master thesis 2023

de Hullu, Cato (author)Along the Dutch coastline, coastal dunes act as the primary sea defence to protect the low-lying areas behind it from flooding. To ensure that these dunes are strong enough to meet national safety standards, models are used to assess their strength. Even though our modelling capabilities have significantly improved over the years, model...master thesis 2023

Kisoensingh, Arvind (author)Flexural shear failure is a brittle failure mode that can occur in reinforced concrete (RC) beams without stirrups due to the combination of flexural and shear stresses. The failure mode begins with vertical flexural cracks at the bottom of the RC beam central span area due to flexural tensile stresses, followed by diagonal cracks. During...master thesis 2023

van Vliet, Sjoerd (author)Different paradigms can be used to evoke brainwaves. These brainwaves can be interpreted as commands that can be used to control different applications. These frameworks that interpret the brainwaves are called brain-computer interfaces. Steady-state visually evoked potentials is one of these paradigms that uses external stimuli flickering at...master thesis 2023

Boeke, Daan (author)This thesis aimed to validate Beekman's patent on how collimation could virtually reduce the focal spot size of an existing small-animal cone beam Computed Tomography (CT) system to diminish the penumbra effect. The ever-remaining drive to improve the spatial resolution in CT for enhanced image quality introduces the need for small focal spot...master thesis 2023

Reda, Abel Kebede (author), Holguin-Veras, Jose (author), Tavasszy, Lorant (author), Gebresenbet, Girma (author), Ljungberg, David (author)The choice of shipment size is a vital decision in logistics and has a strong indirect influence on freight transport demand, via the choice of mode and truck type choice. Through time, shipment sizes can change as a result of new decisions in the logistics process or due to conditions external to the supply chain. This study investigates the...journal article 2023

Shi, Can (author), Fan, Zheng (author), Connolly, David P. (author), Jing, Guoqing (author), Markine, V.L. (author), Guo, Y. (author)Railway ballast performance is dictated by a complex mix of mechanical properties. These effect its performance at the particle level for example in terms of particle degradation, but also at the track system level in terms of settlement and stability. Therefore this paper seeks to develop new understandings of ballast behaviour and identify...review 2023
