Moliner Brotons, A. (author)In high-precision complex mechatronic devices, specifications are mostly affected by the contribution of several disciplines. Thus, in order to facilitate the fulfilment of the specifications, it is crucial to have a well-defined requirement for each sub-system during the entire design process. Model based system engineering (MBSE) is a...master thesis 2021

Weppelman, I.G.C. (author)This thesis is dedicated to the development of a beam blanker for Ultrafast Electron Microscopy. Ultrafast electron microscopy aims to resolve structural dynamics at the nanometer and (sub) picosecond time scale. In these temporal and spatial scales many important processes in physics, chemistry and biology do occur. Examples of these are the...doctoral thesis 2021

Kolekar, S.B. (author)The National Highway Transportation Safety Administration (NHTSA) reports that 94-96% of the road accidents involve human error. These statistics make it seem as if humans are terrible drivers. However, a different set of numbers paint a completely different picture. According to the United States Bureau of Transportation Statistics, the failure...doctoral thesis 2021

Jia, L. (author)To speed up residential energy retrofitting in the Hot Summer and Cold Winter(HSCW) zone, the barriers to retrofitting projects need elimination. Energy retrofitting contributes to improving building quality and living comfort, but has not been accepted by the public. It stems from poor project performance in quality, time, costs, etc. The risk...doctoral thesis 2021

Langeveld, Jilles (author)The current industrial application of carbon capture utilization and storage (CCUS) is limited due to technological drawbacks such as high energy demand and environmental pollution. Ionic liquids (ILs) and deep eutectic solvents (DESs) are considered promising alternative solvents for the capture of carbon dioxide (CO2). DESs are often...master thesis 2021

Hemamalini, S.S. (author)Water electrolysis is a popular energy storage technique used in tandem with many renewable sources to convert the generated energy into storeable hydrogen. The efficiency of water electrolyzers is greatly affected by overpotential losses. Bubble evolution is a unique characteristic of flows in water electrolysis. The evolution of bubbles alter...master thesis 2021

Wesseling, Hendrik (author)The ongoing transition towards sustainable energy has resulted in a large interest in alternative sources. Proton exchange membrane fuel cells (PEMFC) use hydrogen to produce energy without harmful emissions, and they can be used in a range of applications, from mobility to industrial power generation.<br/><br/>One hurdle that still stands...master thesis 2021

Goudswaard, Reinier (author)The growing demand for efficient propulsion systems that operate primarily in hover, has led the ducted rotor configuration to emerge as an increasingly popular design solution. One of the major design parameters for the ducted-rotor assembly is the radial distance between the blade tip and the circumferential wall of the duct, referred to as...master thesis 2021

van den Ende, B. (author)Steel wheels are often essential parts for heavy construction equipment, such as constructed by Huisman. These steel wheels must endure heavy loads. In order to prevent downtime, costs and to guarantee safety, it is important that the steel wheels do not fail. One important failure mode is failure resulting from subsurface initiated cracks. This...master thesis 2021

van Haren, Mick (author)Because of the fortunate absence of great flood events in The Netherlands during the second half of the twentieth century, no physical data was added to the structural understanding of flood fragility on walls. Considering that during the same period the cavity wall became standard in the construction of houses, a certain inconsistency can be...master thesis 2021

Gil Andres, Álvaro (author)Human-robot interaction is a growing field that aims to research and develop communication channels between humans and robots to enhance comfort, safety, and productivity in healthcare, the household, and the industry. Researchers have considered ergonomy-related metrics to compose these channels for physical human-robot collaborative scenarios....master thesis 2021

Caesar, Philipp (author)Completely regenerative life support systems are essential to the long-term exploration of far-off locations in space. The shift from physico-chemical to bio-regenerative life support systems has the potential to be a major step towards that goal. The cultivation of plants as part of such a system not only provides life support functions and...master thesis 2021

van der Wal, Wouter (author)The planning of air cargo across an airlines' network is proven to be a complex problem consisting of multiple subproblems. Currently, all these subproblems are solved sequentially and by hand, resulting in partial solutions instead of an integrated solution. Two of these subproblems are the palletization of items onto ULDs and the scheduling of...master thesis 2021

Alkemade, C. (author)The human body is composed of about 3−4×1013 (30-40 trillion) cells [1]. These cells are all functioning consistently, and working elegantly together, to sustain the organism. Not only humans, but all other living things on earth (from plants to parrots) are composed of cells. Cells are the smallest living building blocks of plants and animals,...doctoral thesis 2021

Armijos Moya, T.E. (author)Several studies have demonstrated the potential of botanical biofiltration and phytoremediation to remove indoor pollutants and improve overall comfort. However, there is a lack of evidence on how indoor greenery affects the Indoor Environmental Quality (IEQ), particularly on Indoor Air Quality (IAQ). The main goal of this research project was...doctoral thesis 2021

van Alderwegen, Earvin (author)Large-scale measures within the river programmes such as Room for the River, Natura2000 and Water Framework Directive have increased the biodiversity in Dutch rivers and have achieved a more natural landscape. However, recent river programmes have shown conflicts between safety against flooding and riverine nature rehabilitation with maintaining...master thesis 2021

Brand, Casper (author)The Kampereiland is an island located at the south eastern part of the IJsselmeer in the middle of the Netherlands. This island serves a purpose to lower water levels in the IJssel- and Vechtdelta during high water, by being inundated. This inundation is meant to result in lower water levels in the IJssel near Kampen. However, the flooding of...master thesis 2021

Dimanidis, Ioannis (author)We propose a novel method combining elements of supervised- and Q-learning for the control of dynamical systems subject to unknown disturbances. By using the Inverse Optimization framework and in-hindsight information we can derive a causal parametric optimization policy that approximates a non-causal MPC expert. Furthermore, we propose a new...master thesis 2021

Champilomatis, Vasilis (author)Heat transfer deterioration has been observed by researchers in turbulent upward flows under the effect of buoyancy. This is a problem for industrial applications since deteriorated heat transfer requires heat exchangers of increased volume and cost. Passive heat transfer enhancement in turbulent mixed convection upward flows through a uniformly...master thesis 2021
