Karbache, Abdelkader (author)Diamagnetism can be used for energy-less levitation, while allowing for friction-free movement of objects in vacuum conditions. A very suitable material can be found in Highly Oriented Pyrolytic Graphite(HOPG), which not only has relatively high diamagnetic properties, but also electrical properties which allow for contactless actuation through...master thesis 2024

den Daas, Michiel (author)Path generation mechanisms are those mechanisms that produce a predetermined path. Such mechanisms are prevalent in daily life, and many devices depend on path generation mechanisms or are derived from path generation mechanisms. One might think of examples such as vehicle suspension, film advance mechanisms or sewing machines. These are...master thesis 2024

Peeters, Lonit (author)Background: Abnormal patellofemoral joint loading patterns may cause patellofemoral pain and may be caused by patellar maltracking. Treatment is aimed at restoring normative patellofemoral kinematics. For this, an accurate estimation of the patellofemoral kinematics is necessary. While 4-dimensional computed tomography (4D-CT) can provide this...master thesis 2024

Geenen, Pieter (author)Coastal structures such as breakwaters can mitigate the erosive effects of sea level rise by protecting shorelines from wave impact. The Reef Enhancing Breakwater (REB) is a modular, permeable structure designed to dissipate wave energy and boost marine biodiversity by providing suitable habitats. This research investigates...master thesis 2024

Heijboer, Dick (author)The lock of Hansweert, located in the province of Zeeland in the Netherlands, serves as a crucial inland shipping node between the Western Scheldt estuary and the Rhine Delta. The outer harbour of the lock complex provides the connection to the Western Scheldt and accommodates waiting facilities for inland ships. The Western Scheldt is a vital...master thesis 2024

de Koning, Daan (author)When drag anchors are no longer suitable for anchoring floating wind turbines to the seabed because of unfavorable soil conditions, it is necessary to use drilled and grouted anchor piles instead. For the installation of such anchor piles it is necessary to drill large diameter holes, with diameters ranging between 1 and 5 meters. The drilling...master thesis 2024

Oosterholt, Torsten (author)Founded in 1910, Boskalis, a leader in offshore operations, contends with limitations in ABB's Ability Marine Advisory System 'OCTOPUS' in predicting maximum vessel motions for heavy-transport vessels (HTVs). Accurate prediction of these motions, especially roll and pitch, is vital for transporting large, heavy structures, as exceeding...master thesis 2024

Kockelkoren, Michiel (author)In recent years, the deployment of ground-based mobile robots has gained more and more interest in various domains. In contrast to other types of mobile robots, legged robots can traverse irregular terrains, climb stairs, and step over obstacles. However, these unique properties intensify the energy demand and require highly advanced perception...master thesis 2024

Koerten, K.O. (author), Abbink, D.A. (author), Zgonnikov, A. (author)Traffic jams occurring on highways cause increased travel time as well as increased fuel consumption and collisions. So-called phantom traffic jams are traffic jams that do not have a clear cause, such as a merging on-ramp or an accident. Phantom traffic jams make up 50% of all traffic jams and result from instabilities in the traffic flow...journal article 2024

Wilde, N. (author), Smith, Stephen L. (author), Alonso-Mora, J. (author)When designing a motion planner for autonomous robots there are usually multiple objectives to be considered. However, a cost function that yields the desired trade-off between objectives is not easily obtainable. A common technique across many applications is to use a weighted sum of relevant objective functions and then carefully adapt the...journal article 2024

Tacx, Paul (author), Habraken, Roel (author), Witvoet, Gert (author), Heertjes, Marcel (author), Oomen, T.A.E. (author)Next-generation deformable mirrors are envisaged to exhibit low-frequency flexible dynamics and to contain a large number of spatially distributed actuators due to increasingly stringent performance requirements. The increasingly complex system characteristics necessitate identifying the flexible dynamic behavior for design validation and...journal article 2024

Chen, Siyuan (author), Laefer, Debra F. (author), Zeng, Xiangding (author), Truong-Hong, Linh (author), Mangina, Eleni (author)Road networks are essential elements of a community's infrastructure and need regular inspection. Present practice requires traffic interruptions and safety risks for inspectors. The road detection system based on vehicle-mounted lasers is also quite mature, offering advantages such as high-precision defect detection, high automation, and...journal article 2024

Kotian, V. (author), Irmak, T. (author), Pool, D.M. (author), Happee, R. (author)Users of automated vehicles will engage in other activities and take their eyes off the road, making them prone to motion sickness. To resolve this, the current paper validates models predicting sickness in response to motion and visual conditions. We validate published models of vestibular and visual sensory integration that have been used...journal article 2024
