Schiermonnikoog is a Dutch barrier island with wide beaches and dunes which are both of importance for recreation as for safety. However, after decades of coastal accretion, in the last years, a strong coastline retreat is observed at the island head in the northwest. In tidal inlets, various forcing conditions of tides, waves, winds and...

System safety and reliability assessment relies on historical data and experts opinion for estimating the required failure probabilities. When data comes from different sources, be it different databases or subject domain experts, the estimation of accurate probabilities would be very challenging, if not impossible, and subject to high epistemic...

Natural fibre (NF) reinforced composites offer high specific mechanical properties and are an ecological alternative to synthetic fibre-reinforced composites. While having great potential, their use today is limited to non-structural applications, mostly with epoxy or polypropylene matrices. This work studies suitable high-performance...

To reduce the cycle time of structural, automotive thermoplastic composites, we investigated the potential of direct thermoplastic melt impregnation of glass fabrics using an injection moulding process. At the high pressures that occur during the process, the effect of the fabric architecture on the impregnation, compaction, volume fraction...

The Netherlands is a densely populated country with a congested road and railway network. Therefore more and more highways are widened and expanded. These wider highways create a demand for bridges which are suited for longer spans. These bridge solutions should constructed with a minimum of hindrance for other traffic. Rijkswaterstaat, also...

Residential self-selection is a well-recognized potential bias in estimating the true effects of the built environment on travel behavior. A popular method to account for residential self-selection is by including people's attitudes towards various modes as additional control variables in the regression. Yet, while attitudes may indeed...

Demand for hydrocarbon fuel is predicted to keep increasing in the coming decades in spite of easily accessible alternative fuels due to shifting geopolitical and economic situations. In order to find new hydrocarbon pockets, we need sharper images of earth’s subsurface. Also, the exploration of other sources of energy like geothermal will...

The combination of centralised automatic bridge and lock (object) control and the increase in traffic has led to a shift in object operations. In the past years, several incidents and accidents have made RWS see the value of innovation when it comes to the control of objects. This master thesis will, therefore, start with defining which problems...

Locating distribution centers is critical for humanitarians in the immediate aftermath of a sudden-onset disaster. A major challenge lies in balancing the complexity and uncertainty of the problem with time and resource constraints. To address this problem, we propose a location–allocation model that divides the topography of affected areas...

This thesis presents a transformable metamaterial, inspired by origami. Generally, metamaterials are build up following the periodicity of Bravais lattices. This study aims to design a structure not following the Bravais lattices, but rather a different type of symmetry which tiles a sphere, in order to expand on current design studies. In this...

The costs and damages that result from cyber security weaknesses are increasing year by year. The cybercrime economy has grown to acquire $600 billion in profits every year, nearly one percent of the global GDP according to a study made by The Center for Strategic and International Studies (CSIS), in collaboration with McAfee. This is likely to...

Organisations find it more and more difficult to deal with our changing times, as our world has drastically changed over the last decades. This has led us to believe that organisational theory and practice from the last decades just does not hold up anymore. They have created organisations that made sense then, but do not necessarily now....

This work proposes a new charge pump design suitable for energy harvesting on small human wearable devices. By using only one system for both cold start and high efficiency harvesting, the required silicon area is heavily reduced. The most fitting energy transducer is determined to be a photovoltaic cell, based on aspects of voltage, power and...

Radiofrequency ablation (RFA) is a localized thermalintervention technique with the purpose to destroy small tumours (< 3 cm) byheating the tumour tissue. Due to various challenges with targeting andvisualisation during RFA, the clinical need of steerable needles is present forradiologists. Helwig, B.P. developed a new...

Multiple studies indicated that the degree of muscle strain is the most relevant parameter in understanding the injury mechanism behind a hamstring strain injury. To monitor this parameter a new system is developed; the Smart Sensor Shorts. The system contains five Inertial Measurement Units (IMUs) integrated in a sports tights. The purpose of...

The global environmental issues are becoming more and more pressing. These issues ask for not only changes on a product-level but also on a system-level (Ceshin, 2013). One of the potential solutions can be to facilitate more sustainable consumption. Sustainable consumption patterns can potentially be created by product-service systems (PSSs)....

Very complex flows can be expensive to compute using current CFD techniques. In this thesis, models based on deep learning were used to replace certain parts of the flow domain, with the objective of replacing well-known regions with simplified models to increase efficiency. To keep the error produced by the deep learning model bounded, a...

In some countries, drying processes use up to 20% of the total energy consumption. Within the agriculture sector, drying of food and flowering products is a necessary step in production. A lot of companies make use of hot air dryers where the heat is gained by burning natural gas. A novel method is to use a heat pump assisted drying systems...

CO2 concentration in the atmosphere is increasing leading to global warming and thus, climate change. Moreover, current renewable technologies such as wind or solar energy only cover the electricity market. A big part of the global energy market is still based on fossil fuels and difficult to electrify. Hence, there is an urgent need to produce...

In football, a lot of hip and thigh muscle injuries occur as a result of high muscular loads due to accelerative leg movements. To prevent muscle damage and optimise performance, it is essential to continuously identify when and how frequent local hip and thigh muscular loads develop in the explosive and dynamic football environment. The...
