The necessity to process signals living in non-Euclidean domains, such as signals defined on the top of a graph, has led to the extension of signal processing techniques to the graph setting. Among different approaches, graph signal processing distinguishes itself by providing a Fourier analysis of these signals. Analogously to the Fourier...

We have developed a tow test setup for the reproducible measurement of the dynamic properties of different types of tethered membrane wings. The test procedure is based on repeatable automated maneuvers with the entire kite system under realistic conditions. By measuring line forces and line angles, we determine the aerodynamic coefficients and...

This dissertation describes how to design dielectric pads that can be used to increase image quality in Magnetic Resonance Imaging, and how to accelerate image reconstruction times using a preconditioner.

Image quality is limited by the signal to noise ratio of a scan. This ratio is increased for higher static magnetic field strengths...

Solid State Lighting (SSL) develops towards small size, high lumen output, high working temperature, and multi-functional applications. These trends are more desirable in miniaturized LED applications such as retrofit G4 LED devices. Retrofit G4 LEDs were chosen in this work as a technical carrier due to the miniaturized size challenge and high...

Saltwater intrusion is a crucial issue in estuaries. The spread of salinity is described by the dispersion coefficient. A purely empirical equation which links the effective tidal average dispersion to the freshwater discharge was developed by Van der Burgh [1972]. Combining it with the salt balance equation, Savenije [1986] derived a one...

With the growth of global population, the big cities become increasingly crowded. It is not rare to see large crowds in public transportations and events with masses of visitors, such as music festivals and football matches. The question “How to deal with crowds” is receiving attention, both from academia and practical crowd management.
This...

Wheels are critical components of trains, and their conditions should be therefore monitored.Wheel defects change the wheel-rail contact and cause high impact forces thatare damaging for tracks and trains. Wheel defects can also cause unexpected failuresthat reduce the availability and reliability of the railway system. Several monitoring...

Kenya Water Services Regulatory Board (WASREB) Impact Report indicates a stagnation in water coverage at 55 percent, for the last three years, contrary to the 2015 target of 80 percent. One main reason for the stagnation is weak cross-county cooperation between hydrologically interdependent governments. WASREB has little guidance on what...

Growing importance of hydrogels in various areas of human life has led to increasing need in controlling their properties, which is generally achieved by adjusting hydrogels shape and microstructure. Even though standard microfabrication and microstructuring techniques can be currently applied in hydrogel research, the variety of properties of...

Abstract: The aerodynamic drag of a human-scale wind tunnel model is obtained from large-scale particle tracking velocimetry measurements invoking the conservation of momentum in a control volume surrounding the model. Lagrangian particle tracking is employed to obtain the velocity and static pressure statistics in a thin volume in the wake...

The realization of interfaces between different transition metal oxides has heralded a new era of materials and physics research. Notably, it enabled a uniquely diverse set of coexisting physical properties to be combined with an ever-increasing degree of experimental control. The primary focus of this thesis is the celebrated interface between...

Artificial illumination has had profound and far-reaching impacts on the development, use, and perceptions of urban nights, and has brought with it many benefits. However, in recent years its adverse costs and effects – commonly referred to as light pollution – have emerged as a topic of concern. Nighttime lighting uses enormous amounts of...

Although being a crucial step in structural design of laminated composites, prediction of their long-term mechanical performance remains a challenging task for which no comprehensive and reliable solution is currently available. Nevertheless, structures such as wind turbine blades, of which laminated composites constitute the main load bearing...

The aim of this project was the development of the scientific basis for methodologies that enable the production of renewable sustainable cement (i.e. BioCement) based on ashes derived from the conversion of biomass residues. Within this project, biomass ash and derived products were developed at the laboratory scale, and their functionality was...

Dutch citizens on welfare have to volunteer at Civil Society Organizations (CSOs) in return for their benefits. Through applying the ‘worlds of justification’ of Boltanski and Thévenot, this article aims to provide a better theoretical and empirical understanding of social justice of policies that obligate welfare clients to participate in CSOs....

The conventional development of a new automobile starts with a first proportional model. In this model, the exterior geometry of a car can be distinguished into vehicle, power train portfolio, market requests, safety requirements, and design target. The interior design results from the proportional model with specific characteristics, such as...

Nearly 200 parties signed and committed to the Paris agreement in 2017, which comprises the long-term goal to keep the average global temperature increase well below 2 degrees above pre-industrial levels. Virtually all possible scenarios drafted to reach this goal include a strongly increased use of biofuels for transport by land, sea and air....

The concept of the Global Petroleumspace is an analytical tool which engages the roles which different oil actors play in the development of new urban ideas and built forms. Coined by Hein, this concept contributes to enriching our understanding of globalization, modernity, and architectural history and their impacts on space through time....
