Gas giant satellites are generally believed to form in circumplanetary disks (CPDs): a gas disk containing solid particles that accumulate to form moons over time. The discoveries by the Cassini­ Huygens mission have led to a revision of the birth environment of the Saturnian system. The aim of this thesis is to constrain the formation...

On the railway line between Zutphen and Hengelo in the Netherlands, rolling contact fatigue (RCF) defects are found at the surface of the rail. RCF is a known hazard to the safe operation of railways, the cracks can cause transverse rail fracture, which may result in derailment. Contrary to convention, the traffic on this particular railway is...

Within a Protoplanetary disk (PPD), planets form from micron sized particles, but what are the processes taken for planet formation? How does the evolution of micron sized particles via settlement and coagulation lead to the gigantic planets as the ones in our Solar System? This thesis explores the planet formation process of pebble accretion...

Trivalent chromium (Cr(III)) is one of the most promising non-toxic replacements for hexavalent chromium (Cr(VI)) coatings in the steel packaging industry. The application of a chromium layer to packaging steel is essential for providing a protective layer on the steel packaging’s external surface area, which prevents corrosion during its use....

In the last decades, more and more complex societal and environmental challenges are rising. Social Innovation is an emerging and promising framework to tackle complex global challenges at the local level of urban contexts. These projects are socially, culturally and contextually embedded and highly dependent on the local ecosystem of resources....

As a result of the high failure costs and many project delays in the construction industry, collaborative contracts emerged in an attempt to improve project performance. The project alliance was one of them. This integrative way of working requires a focus on the human aspects, because people from different organisational cultures are brought...

The application of autonomous robotic vehicles to explore unknown environments is a growing field of interest in the research community. This thesis report studies the practical implementation of employing three autonomous vehicles to navigate towards a signal emitting source in an unknown environment. The group of autonomous vehicles is...

Certain Formation Flying missions rely on their orbital control thrusters to maintain the formation, making a Fault Detection and Isolation (FDI) system that is capable of detecting thruster faults very valuable. In addition, communication between satellites in a formation can be expensive. In this thesis, a distributed FDI approach was...

The mission control of a fixed-wings UAV is slightly more complex compared to other models like quad-rotors or unicycles since the dynamic of a fixed-wing aircraft does not allow rapid direction changes or stop-rotate-go type of movements. Those restriction needs to be taken into consideration when building a mission control system, moreover,...

The current production of geothermal heat is not yet considered completely sustainable, since CO2 is emitted. The majority of the emissions from geothermal energy are related to formation gas, for the majority consisting of CO2 and methane (CH4). The amount of (resulting) CO2 emissions due to formation gas is determined by the composition and...

The use of distributed multi-agent formation control for non-holonomic mobile robots shows great promise in practical environments. In this thesis, a Robot Operating System (ROS) package is developed in which various formation control algorithms are implemented for use on a group of skid-steer drive mobile robots. These formation control...

The energy grid is transitioning from a centrally controlled demand response system to a decentralized supply response system. There are multiple reasons for this, but the main one is the need to transition to a low carbon energy system to tackle climate change and decrease our dependency on non-renewable energy sources. Next to this consumers...

This thesis aims to improve our understanding of the role of ices in planet forming discs, known as protoplanetary discs. Computer models of such discs have been used extensively by the community to understand and predict the observational data. It has always been a challenge to observe ices in the discs and their optical appearance is largely...

This study proposes a novel coordination approach for the purpose of formation flying in civil aviation. Inspired by the natural phenomenon of bird flight, formation flying has proven to reduce the aerodynamic drag of trailing aircraft that follow the wake of a leader. We investigate the network scale fuel-savings potential of this operational...

Formation control of autonomous surface vessels (ASVs) is researched extensively in the last years, since it has promising applications. However very few designed strategies have been validated during real experiments. In this research, two<br/>control methods for distributed leader-follower formation control are proposed: A Nonlinear Model...

Internal erosion is a frequent cause of dike failure, also known as piping or backward erosion. Uplift is considered a submechanism of internal erosion, together with heave and piping, where all three submechanisms must occur for the dike to reach a failure condition. The principle of the uplift phenomenon is straightforward: it occurs when high...

Water injection is widely used in the petroleum industry for the increase of hydrocarbon recovery or disposal of wastewater. Water production and injection are the primary mechanisms in Geothermal Energy. Both include injecting water into a porous formation under matrix injection conditions. While maintaining water injection is vital in these...

In this paper we introduce a setup to investigate aeolian saltation and surface dynamics on a centimetre spatial resolution and a sub second temporal resolution. We develop a Lagrangian saltation model and a high-resolution surface model, which we couple to each other and to a turbulence resolving large eddy simulation model. The simulated...

OKademy is a start-up that wants to improve the healthcare in the Netherlands by improving the process by which graduated medical students are being matched to a hospital team. This is needed since there is a lack of surgery<br/>assistants, while graduate students need to wait on average six months to start their work in a hospital. To match...
