Acidizing is a widely used technique for intensification of geothermal wells. At certain conditions, acid injection results in a formation of highly conductive channels, e.g. wormholes. The associated rock matrix dissolution is highly nonlinear and may influence the fluid flow as well as rock properties. Wormhole patterns and breakthrough time...

When containers are transported on synchromodal bookings from their origin to their destination, the transport supplier can decide which combination of trucks, trains, and ships to use. This gives transport suppliers many options to route the container through the synchromodal network. Current literature on the individual routing of containers...

Some propellants currently used in space propulsion have the disadvantage of being dangerous to humans and the environment. A wellknown example of this are hydrazine and its derivatives which are toxic, corrosive, and carcinogenic. These disadvantages have led to a search for less hazardous storable liquid propellants, often referred to as green...

Integrated circuits (ICs) are susceptible to damage by Electrostatic Discharge (ESD), which necessitates protection diodes. However, these diodes can cause leakage currents in the range of picoamperes, dominating the input current of CMOS ICs. This thesis presents the implementation of a low leakage bootstrapped ESD protection circuit for...

Applications for thermoelastic metamaterials, in which extremely positive, zero or negative thermal expansion is desired, are plentiful. Nevertheless they are rarely applied, due to their poor manufacturability. To enhance their applicability, a topology optimization framework is proposed and verified, able to generate finite thermoelastic...

Micro air vehicles (MAVs) are increasingly being considered for aerial tasks such as delivery of goods and surveillance due to their lightweight, compact design and manoeuvrability. To safely and reliably carry out these tasks and navigate to its objective, especially in complex and cluttered environments, the MAV is also required to sense and...

The concept of Urban Air Mobility (UAM) services was created mainly in response to traffic congestions. In this research we focus on UAM services such as those provided by Uber Elevate. We therefore present a framework to solve the Urban Air Mobility Problem with Time Windows (UAMP-TW) under dynamic demand, using an Adaptive Large Neighborhood...

The Dutch heating transition involves changing the heating systems of eight million buildings to a sustainable alternative by 2050. Many heating system technologies are available, but deciding which systems are cheapest for all these buildings is a difficult question to answer. Local policymakers are increasingly making use of heating transition...

Robots that use legged locomotion have the ability to overcome obstacles and can negotiate a wide range of difficult terrains, such as encountered in outer-space missions. In many practical scenarios however, their applicability is still limited, mainly due to insufficient speed and efficiency. On the other hand, robots that use wheeled...

This research aims to identify the underlying mechanisms of the cost of rework related to constructability in Dutch marine infrastructure projects. Despite extensive previous research on the cost of rework, and constructability, the underlying mechanisms within executed projects in the Netherlands have not yet been observed from research....

Railway sleepers form an important part of a classic track structure. Sleepers exists in their current form for a long time. The transition from wood to concrete sleeper has been made, but wood is still used and present in many track sections. As creosoted wooden sleepers are not allowed to be installed on the tracks anymore the search for...

Learning human motion prediction models online is key for autonomous navigation in unknown dynamic scenarios. Previous works focus solely on improving prediction network architectures, whilst training them offline. This paper introduces a self-supervised continual learning framework that continuously improves data-driven pedestrian trajectory...

Climate change and greenhouse gas emissions have been at the forefront of both public and academic debate for some years. Although the shipping industry has managed to remain relatively free of climate regulation this is changing with the IMO goals for 2050. The military sector has also escaped scrutiny on sustainability issues. But this is also...

MRI is an non-invasive imaging technique used by many physicians to diagnose and treat diseases. The technique however is still very expensive and thus out of reach for developing countries. This has led to the goal to design a low-cost MRI system. The challenges that arise from this system make it necessary to design coils in a different way...

Contemporary optical communication terminals are capable of higher data rates, over longer distances for less power compared to traditional radio communication terminals. As of writing, these terminals are almost exclusively single beam compatible. This thesis describes dedicated multi-beam terminal with COTS components. The design study used a...

Climate change and global warming are some of the greatest challenges the world is currently facing. This challenge has structural impacts on the natural environment as well as on human well-being. As a response to the concerns regarding climate change, the Netherlands started a renewable energy transition. Nevertheless, the realisation of the...

Stand capacity assessment is an essential factor in airport planning and design due to the large investments associated with airport development. Fulfilling anticipated demand while still considering future growth is key in airport master planning. In this paper, a mixed-integer linear programming optimisation model is proposed, which determines...

The lower Ems river suffers from hyper-turbid conditions. These conditions are caused by channel deepening over the last 50 years, resulting in an asymmetrical tidal wave. This asymmetry has resulted in an increased<br/>import of sediment into the Ems river. Recently some effort has gone into determining whether or not the local tidal barrier ...

In this thesis, we introduce the quantum groups Uq(SL(2,C)) and Aq(SL(2,C)) as Hopf algebras. We study their representations, including their similarities and differences with the classical theory. We show that the eigenvectors of Koorwinder's twisted primitive elements of Uq(SU(2)) are dual q-Krawtchouk polynomials. We use this explicit...

This research aims to identify gain-and-pain-sharing methods to foster a collaborative environment to create win-win situations and create mutual objectives. To do so, gain-and-pain-sharing methods that can positively influence a collaborative environment are explored. This study is restricted to the Dutch construction sector because it is for...
