Zeng, Q. (author)The traditional approach of extrapolating the experimentally measured model resistance of a ship to full scale is based on the Froude assumption or the form factor assumption, where the viscous part and wave-making part of the resistance are dealt with in deep water. In shallow water, however, the water-depth dependency of flat-plate/ship...doctoral thesis 2019

Peters, O.A.J. (author)Dry transporting large heavy floating structures has been an important development in the innovative history of Heavy Marine Transport. This is done by carrying these type of cargoes on the deck of Heavy Transport Vessels. Loading and discharge is preformed by submerging the transport vessel, and positioning the cargo above the deck using tugger...doctoral thesis 2019

Bos, R.A. (author)Orthoses have evolved from simply maintaining bone fractures and correcting spinal deformities to full mechatronic systems that can read a person’s intention and translate that into a desired motion or force path. A vast variety in pathologies (e.g., stroke, muscular dystrophies), applications (e.g., daily assistance, research) and environments ...doctoral thesis 2019

Visser, T. (author)The decay of satellite orbits has been used extensively to obtain thermospheric density measurements. With the introduction of accelerometers in spacecraft, the spatial resolution of these data could be increased. At the same time, the direction of the measured acceleration provides a measure for the direction of the incoming flow, and therefore...doctoral thesis 2019

Li, Y. (author)Context is interpreted as a body of information dynamically created by a pattern of entities and relationships over a history of situations. Computational handling of dynamically changing contexts and the consideration of rapidly changing situations in awareness building, situated reasoning, and proactive adaptation of smart cyberphysical...doctoral thesis 2019

Baldacchino, D. (author)Vortex generators have become a ubiquitous sight on the modern wind turbine blade. These small, passive devices can increase the energy extraction potential of a rotor, but their subtle footprint disguises the technical difficulties associated with designing and integrating them onto wind turbine blades. The complexity of rotor inflow and the...doctoral thesis 2019

Khajeh Salehani, M. (author)The main objective of this thesis is to obtain a better understanding of adhesive contacts and their frictional behaviour. Both natural and man-made surfaces are rough over a wide range of length scales. Tribological studies of rough surfaces need to account for the interactions between these asperities. In this work a sim- ple atomistically...doctoral thesis 2019

Shakerifard, B. (author)Global warming, continuous demand on energy from fossil fuels as a limited natural resource, and costumers’ high expectations regarding product quality are three global challenges that the automotive industry is facing. Fuel consumption reduction has a significant impact on preserving fossil fuels, lowering fossil fuel dependency and the CO2...doctoral thesis 2019

Sun, Junzi (author)A large number of stakeholders exist in the modern air traffic management ecosystem. Air transportation studies benefit from collaboration and the sharing of knowledge and findings between these different players. However, not all parties have equal access to information. Due to the lack of open-source tools and models, it is not always possible...doctoral thesis 2019

Wu, P. (author)The European Union and the United States are proposing to bring in more strict flight vehicle emission criteria in their reports of the high‐level groups on aviation research, i.e. EU Flightpath 2050 and US Destination 2025. More fuel‐efficient aircraft must be developed to achieve this target. Moreover, the increasingly competitive aviation...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

Huang, Y. (author)In advanced robotic applications such as robotic locomotion, vehicle and flight simulators, and material test devices, there are higher requirements on stiffness, robustness and power ability for the mechanical structure and the actuator. Hence, it is common for such applications to use parallel manipulators and hydraulic actuators, due to their...doctoral thesis 2019

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...doctoral thesis 2019

Smeur, E.J.J. (author)Micro Air Vehicles (MAVs) can perform many useful tasks, such as mapping and delivery. For these tasks either rotorcraft are used, which can hover but are not very efficient, or fixed wing vehicles, which are efficient but can not hover. Hybrid MAVs combine the hovering of a rotorcraft with the efficiency of a fixed wing. The reason that these...doctoral thesis 2018
