Since 2011, an electronic registration system, called the OV chip card, has been in use in the Netherlands for the payment of all public transport. As a result, the Dutch Railways (NS) have implemented all the necessary equipment to support the sales and validation processes of this system. Another company (Thales, the agent) has been hired to...

Increasingly large sand nourishments are used for the maintenance of sandy coasts around the world. There is, however, still very limited understanding of their behaviour (i.e. redistribution) and effects on the marine environment. This PhD thesis explores the morphological reshaping of shoreface nourishments (i.e. long bunds of sand placed at...

Ballistic capture is a relatively novel concept in interplanetary mission design with the potential to make Mars and other targets in the Solar System more accessible. A complete end-to-end interplanetary mission from an Earth-bound orbit to a stable science orbit around Mars (in this case, an areostationary orbit) has been conducted using this...

It is hard to imagine a world without bridges. Bridges lie at the heart of our civilization bringing growth and prosperity to our society. It is by virtue of bridges that communities are able to physically connect to new people and to new places that were previously disconnected. However, bridges are more than mere functional assets. A well...

Concrete is a brittle composite material that easily fractures under tension. Due to the fact that the early-age deformation of the concrete member is restrained by adjoining structures, cracking can occur throughout the concrete prior to application of any load. The cracks would provide preferential access for aggressive agents penetrating in...

The beginning of the millenium has initiated the transformation of the space market to a globally private space industry, distinguished by relatively young and commercially minded aerospace businesses, which is known as NewSpace. Airbus Defence and Space Netherlands B.V. (Airbus DS NL) aspires to anticipate on this transition and has initiated...

The Dutch government has announced that 7 million houses and 1 million buildings in the service sector need to be provided by sustainable heat in 2050 (Klimaatberaad, 2018b). This is an enormous challenge considering that over 90 percent of the houses and service sector buildings in the Netherlands are currently heated by the local combustion of...

Road transport heavily relies on fossil fuels and contributes to a series of problems including pollution, greenhouse gas emissions and fuel dependence. Replacing fossil-fuel powered vehicles with electric vehicles (EV) on a large scale is regarded as a potential or even necessary solution to alleviate these problems. Therefore, many national...

Massive Open Online Courses (MOOCs), as one of the popular options for people to receive education and learn, are endowed with the mission to educate the world. Typically, there are two types of MOOC platforms: topic-agnostic and topic-specific. Topic-agnostic platforms such as edX and Coursera provide courses covering a wide range of topics,...

This thesis investigates the efficiency of wind energy conversion from three aerodynamic perspectives. The first, purely theoretical, assumes steady inviscid flow conditions to identify multi-rotor setups that can extract more power per unit area than isolated rotors. The second, more practical perspective, assesses the extent to which site...

Pilots are an important asset in the operations of airlines, as with insufficient pilots, an airline cannot operate the planned schedule. The long-term crew planning problem aims to optimally plan the supply and demand for pilots as well as methods and strategies for closing the gap between these. The demand is determined by the number of pilots...

With the rising demands from customers and users and the development of ever advanced technologies, many space missions nowadays require more than one satellite to fulfill their mission objectives. Although replacing single satellite systems (SSSs) by multiple satellite systems (MSSs) offers advantages, such as enhanced spatial and temporal...

From shallow to deep water, from the well to the ship, from the offshore field to shore or between countries, many kilometres of offshore pipelines for transportation of hydrocarbons (oil and gas) have been installed over the last decades. Allseas’ Tog Mor is a shallow water pipelay barge capable of laying pipes up to a water depth of 25 meters....

It is difficult to accurately predict the strength of masonry and concrete structures. The most widely used method for simulating their behaviour is finite element analysis with the Newton-Raphson method and arch length control. However, the Newton-Raphson method can diverge and not produce a result, for example in bifurcations or during snap...

This study aims at improving the hydrological process understanding of the semi-arid and transboundary Incomati river basin to enable better water management. Comprehensive statistical and trend analysis of rainfall and streamflow were conducted, and the Indicators of Hydrological Alteration tool was deployed to describe the streamflow regime...

In this research, known theory and methods for electric networks are translated and applied to gas transport networks.

The networks are represented by directed graphs with their corresponding incidence matrices. The theory about these is extensively discussed in addition to their relevance to Kirchoff's Circuit Laws.

During the primary oil recovery, wells are drilled into the reservoir, and due to natural driving forces, the oil flows to the surface through these production wells. Unfortunately, the production of oil in this first stage is typically between only five and ten percent of the oil in place in the reservoir. In the secondary oil recovery some...

Organisations need to go through continuous change in order to maintain a sustainable competitive advantage. This change is often expressed in a vision which should engage and involve all stakeholders. However, implementing change successfully turns out to be a challenge since two in three change processes stall. Ink Strategy is a visual...

A lot of research has been done on the behaviour of pneumatic tyres and this has led to various tyre models and a lot of measurement data. However, in the specific field of bicycle tyres, not so much measurement data is available. However, in 2013 Andrew Dressel received the Degree of Doctor of Philosophy in Engineering at the University of...
