The rollercoaster Baron 1898 in the Efteling is a unique and thrilling experience. However, the Safety Department observes an unwanted phenomenon: Occasionally, guests do not safely store their small personal belongings, such as phones, which then fall out during the ride. The result is a lost or broken phone or other personal valuable. Not...

This thesis reports on the research and design of a real-time Time-Varying Model Predictive Control (TVMPC) scheme to stabilize a tilt-rotor aircraft with four independently tilting rotors. The aircraft design stems from a prototype system constructed by the drone technology start-up Avy.
First, a motivation is presented for implementation...

A high drop-out rate is present during current-day air traffic controller (ATCo) training, because the required expertise level is not reached. The determination of the expertise level of ATCo students is currently performed using subjective assessments at a late stage in the training by means of high-fidelity simulator sessions. It is desired...

Enabling mobile robots to autonomously navigate complex environments is essential for real-world deployment in commercial, industrial, military, health care, and domestic settings. Prior methods approach this problem by having the robot maintain an internal map of the world and then use a localization and planning method to navigate through the...

Persistent surveillance is an urgent proficiency. For security, surveillance cameras are a strong asset as they support the automatic tracking of people and are directly interpretable by a human operator. Radar on the other hand can be used under a broad range of circumstances: radar can penetrate mediums such as clouds, fogs, mist and snow, and...

An analytical low-thrust design tool for orbits around Earth has been developed which takes perturbations into account. The Simplified General Perturbations 4 model (SGP4) is combined with Edelbaum’s analytical low-thrust trajectory model. This resulted in the SGP4-LT tool which required an iterative version of SGP4. To obtain this iterative...

This thesis explores the use of InSAR data for building monitoring. The area of main interest is the city centre of Amsterdam, where quay wall replacements are necessary on a large scale. In Amsterdam, the foundation quality needs to be checked before construction activities nearby are performed, such as a quay wall replacement. Levelling...

Many movable bridges, built in the 1950’s and 1960’s, reach their end of service life or do not meet future traffic demands. Renovation of those bridge, if possible, is preferred over newly built from an economical point of view. Fibre-reinforced polymer (FRP) decks prove to be excellent for retrofitting bridge decks compared to traditional...

The International Maritime Organization (IMO) has been working on the reduction of emissions in sea shipping. This has been done by stricter regulations over the past years in the form of emission limits. An important element which determines the success of this reduction, is the enforcement of the emission limits. A drawback of the current...

Constructing a dam across a tidal basin has alway been a long-term integral solution to many water related problems of the surrounding area such as flooding, river control and fresh water storage. However, immense challenges are accompanied with the closure works of large basins. This research treats the closure strategy to close the Gulf of...

In this thesis, a we have designed and fabricated a Josephson Parametric Amplifier (JPA) using a new double-angle evaporation method without a Dolan bridge. We have found and resolved several issues in the fabrication procedure, but it requires further tuning before being fully functional. We have also simulated the behaviour of a general...

Hydrogen technology offers a promising opportunity to mitigate problems that arise due to the energy transition. It can enable storage and balancing for surplus in electricity production from intermittent resources as solar energy and wind power. Electrolysis converts green electricity into hydrogen. Hydrogen is suggested to be introduced into...

Waterborn transport currently runs on diesel driven Internal Combustion Engines
(ICE). To reduce Green House Gas (GHG) emissions an option is to shift towards
alternative fuels, like alcohols. This thesis focusses on methanol in ICEs. The
combustion of methanol in ICEs can be done in numerous manners, where fuel
altering,...

The construction of infrastructure in the Netherlands is initiated by the Dutch government and performed in the form of projects. Yearly about €8 billion is spent on infrastructure and in the construction sector 50% of the projects are initiated by public clients. Project management methodologies are the working methods of these public clients....

In Nala Sopara, In the Mumbai metropolitan region, we can find many one-story dwelling blocks called ‘baithi chawls’. Due to the increasing demand for housing in this area, the developers have shifted their focus to the build of four to five-story chawls. We can distinguish two forms of chawl development; the redevelopment and the new...

A conventional dynamic positioning system is used to control vessel motions in the horizontal plane, i.e. surge, sway and yaw. However, the safety and operability of several offshore operations can be increased when also the roll motion is actively controlled, especially in beam seas. A control system model is proposed for combined thruster...

The development of swarm robotics strives for resilience, a key factor in this is energy supply. Without energy a robot swarm cannot operate, so a self sustaining power management system is of great importance. In this thesis, the design of the power management system control hardware and firmware for the new DeciZebro is discussed. The power...

Normal linear springs have spring characteristics that are often too simplistic for complex applications. For instance in balancing applications, constant force or negative stiffness mechanisms are required. A tape loop, which consists of a two-fold tape spring, is a compliant shell mechanism which can act as a force generator with theoretically...

This thesis describes the process of the development of the MuseumMakers application: a tool for providing constructive feedback by children to museums. The tool only focuses on regular visits, because it is more difficult to collect feedback from younger visitors. This is due to the fact there is no interaction between museum employees and...

Water scarcity and unequal distribution of water to different social groups is a problem around the world - mostly in arid and dry climatological conditions. In Israel and the Palestinian Territories water is used as a territorial tool in what I call 'spaces of conflict and opposition'. What could the role of e.g. an architect be in spaces of...
