La Porte, Jesse (author)This thesis investigates the potential of a semi-passive trailing-edge flap on a large conceptual wind turbine. The mechanism passively reacts to blade and tower accelerations by changing the airfoil camber, opposing the dynamic loads on the turbine. An active element is present, which influences the mean of the flap oscillation. First, a low...master thesis 2019

Durieux, Bram (author)The extraordinary capability of swarming ant species in route finding and foraging efficiency through trail trail development has been studied for many years. Scientists have been able to capture the behavior of individual ants in control algorithms and used the resulting artificial swarm of ants to solve difficult problems. These problems...master thesis 2019

Verlaan, Bram (author)Development of the autonomous vehicle has been a trending topic over the last few years. The automotive industry is continuously developing Advanced Driver-Assistance Systems (ADAS) that partially take over the driver’s workload. This has resulted in an increase in vehicle safety and a decrease in fatal crashes [1]. Full vehicle autonomy has not...master thesis 2019

van der Heijden, Ties (author)This thesis investigates the potential of a large pumping station in IJmuiden, the Nether-lands, for participating in Demand Response. Due to climate change, renewable energy is onthe rise. The intermittency of energy, together with its unpredictable supply, are a big hurdlefor the energy transition. Two methods are promising solutions to this...master thesis 2019

Karasek, M. (author), Perçin, M. (author), Cunis, Torbjørn (author), van Oudheusden, B.W. (author), de Wagter, C. (author), Remes, B.D.W. (author), de Croon, G.C.H.E. (author)Flow visualisations are essential to better understand the unsteady aerodynamics of flapping wing flight. The issues inherent to animal experiments, such as poor controllability and unnatural flapping when tethered, can be avoided by using robotic flyers that promise for a more systematic and repeatable methodology. Here, we present a new...journal article 2019

Horváth, K. (author), van Esch, B. (author), Vreeken, D. (author), Pothof, I.W.M. (author), Baayen, J. (author)This study presents convex modeling of drainage pumps so that real-time control systems can be implemented to minimize their energy use. A convex model is built based on pump curves and then used in mixed-integer optimization to allow pumps to be turned on or off. It is implemented as an extension to the open source software package RTC-Tools...journal article 2019

Kajak, K. M. (author), Karasek, M. (author), Chu, Q. P. (author), de Croon, G.C.H.E. (author)Recently, several insect- and hummingbird-inspired tailless flapping wing robots have been introduced. However, their flight dynamics, which are likely to be similar to that of their biological counterparts, remain yet to be fully understood. We propose a minimal dynamic model that is not only validated with experimental data, but also able...journal article 2019

Kist, Martijn (author)Pioneering Spirit, Allseas's largest pipelay vessel, will be outfitted with a novel Jacket Lift System (JLS). A jacket refers to the steel frame which supports the topside of a fixed offshore platform. The Pioneering Spirit was already capable of lifting the topsides of offshore platforms, like the former oil platform Brent Delta, but would have...master thesis 2018

Bakker, Ilse (author)Kitepower is a start up that generates energy using kites. The Kitepower system consists of airborne components, and a ground station where a drum is connected to a generator/electrical motor. For generating energy a so called pumping cycle is performed. In a pumping cycle energy is generated during the traction phase when the kite pulls the...bachelor thesis 2018
