Despite the progress in the field of longitudinal formations of automated vehicles, only recently an interpretation of longitudinal platooning has been given in the framework of disturbance decoupling, i.e. the problem of making a controlled output independent of a disturbance. The appealing feature of this interpretation is that the...

Power availability to preserve propulsion is a vital issue in the shipping industry which relies on persistent power generation and maintaining the stability of the power and propulsion system. Since the introduction of on-board all-electric Direct Current Power and Propulsion Systems (DC-PPS) with hybrid power generation, which are more...

With standard aircraft configurations reaching their limits in efficiency, new aircraft configurations are being theorized and analyzed. One type of analysis is remotely piloted scaled flight tests. One of the aspects that can be analyzed through remotely piloted scaled flight tests is the dynamic behavior of the aircraft. This thesis shows a...

A new aircraft configuration, the Delft University Unconventional Configuration (DUUC), was recently invented by the Flight Performance and Propulsion group at TU Delft. As a solution to the concerns regarding the environmental and health impact due to increasing demand of air travel. The DUUC has a characteristic feature which consist of two...

To protect the Netherlands better from flooding, and with an eye on sea-level rise in the rest of the world, more accurate assessments are needed for dykes. The calculation for the most occurring failure mechanism in dykes, i.e. macro-instability, is limited by not being able to calculate large deformation when sliding occurs within a dyke. The...

The Dutch Water board revised their guidelines for the safety assessment of dikes in 2017. A major change for the assessment of macro-stability is the use of the SHANSEP method to estimate the strength of impermeable cohesive layers. The failure probabilities are estimated with a deterministic analysis using limit equilibrium methods. The use of...

Two types of calculations are currently used to assess dikes for macro stability. These are the semi-probabilistic calculation and the probabilistic calculation. In practice, the semi-probabilistic calculation is currently mostly used. However, the probabilistic calculation is the most accurate calculation of the two methods resulting in the...

This thesis contains two contributions to the stabilization of visually guided robotic lampreys: the head stabilization method and the head-led target tracking design. Both approach the problem that camera inputs, attached to the head segment, are disturbed due to the participation of the head in the locomotion gait of the robot. Head...

People in healthcare, warehousing, and the agriculture sector all have one thing in common. They require labour which can be demanding on the human body, this could lead to problems in the long term. A way to alleviate these problems is to use a passive exoskeleton. While passive exoskeletons can have a variety of different use cases and types...

The goal of this thesis is to look into the possibilities of making origami neutrally stable. This is wanted because the inherent stiffness of origami mechanisms introduces unwanted artifacts such as a higher actuation force, and the mechanism not following the theoretical kinematics. By making an origami mechanism neutrally stable the inherent...

This research identifies a method to evaluate the fairness and stability of existing Pareto optimal policies in the context of transboundary water resource allocations. Using the case study of the Susquehanna river basin, the fairness of efficient policies was evaluated using utilitarianism, egalitarianism and prioritarianism. Stability was...

Perovskite Solar Cells are an increasing attraction in research with great strides in performance efficiencies. But their commercialization is far from fruition, due to persistent issues. Stability under prolonged exposure to external stresses is a major concern. Furthermore, the adaption of upscaling technologies in research is presently slow....

Simulations of a spar-type floating wind turbine supporting the DTU 10 MW reference turbine under fitted atmospheric conditions are performed. Atmospheric conditions are modelled using the turbulent models recommended by the IEC: the Mann model and the IEC Kaimal and exponential coherence model. Model parameters are fitted to measurements at the...

Landslides pose a risks to the communities settled in their vicinity. They pose a threat to human lives and significant economical damage to the affected communities. As the scientific community agrees that the climate change will further increase the risks associated with landslides, it is important to develop a reliable, cost effective and...

The power production of downstream wind turbines in a wind farm is significantly impacted by wake effects of upstream turbines. Improving the layout optimization process could reduce these wake losses and therefore result in more efficient wind farms. The wakes are also affected by atmospheric stability conditions, as stable conditions lead to a...

The traffic density of small aerial vehicles operating within urban environments is expected to increase significantly in the near future. This urban environment is highly constrained due to being limited to the low-altitude airspace directly above the existing road network. To increase understanding of the factors influencing the capacity of...

This work is a bachelor thesis featuring a collection of explorations of the Kuramoto model in the presence of noise in one and two dimensions. The model was explored analytically and numerically. It contains a study of literature and new analytical derivations. An attempt to link the fraction of oscillators to the order parameter resulted in...

A new approach is proposed which uses concepts of both the limit equilibrium method (LEM) and finite element method (FEM) to analyse slope stability. The main limitation of the LEM is that it can give an incorrect display of the initial stresses. The FEM is able to overcome this limitation, however, it uses the shear strength reduction method ...

Royal IHC is known for building large dredging vessels which collect soil from the seabed. The vessel needs to remain in position, called dynamic positioning, which is done by large thrusters. These are mostly electrically powered thus the total amount of required power can range up to 50 MWs. Royal IHC wants to investigate the possibility of a...

Propellers were the first means of powered propulsion for aircraft. However the development of propellers stalled due to the growing interest in jet propulsion. Due to the growing interest in more fuel efficient and environmentally responsible aviation, propeller research is currently seeing a resurgence. <br/><br/>Wingtip-mounted propellers are...
