Over the last decades the costs of drilling oil and gas wells have soared. One of the ways to reduce drilling costs is to drill the wells at a faster rate. This can be done by changing operational parameters, like the rotational velocity of the drill string or the weight on the bit. However, increasing these parameters can lead to violent...

This Thesis report will discuss the development of embedded control systems for process control (in this case for the calibration of a gas analyser). The main research question being: Which control algorithm will be able to achieve the most optimal calibration procedure? A calibration bench which will be used to create a specific condition (gas...

Due to the growing amount of air traveller in the coming decades, there is an increasing interest to improve the experience of the passengers. Especially travelling with hold-luggage is a big pain point and stress factor for passengers’. A new way of looking at this problem is providing a baggage pick-up and delivery service by independent...

Het IJmond- gebied omvat de haven van Amsterdam, het Noordzeekanaal en de sluizen van IJmuiden. De probleemstelling richt zich op de planningsmethodiek voor de afwikkeling van de scheepvaart in dit gebied. Het afstudeerproject (in opdracht van DGSM) betreft het ontwikkelen van een simulatiemodel waarin de gehanteerde planningsmethodiek opgenomen...

Many bridges in The Netherlands are built around 1960-1970 and currently reach their designed service life of 50 years. The traffic loads are increasing and new insights in the behaviour of constructions are obtained. Therefore there are doubts about safety of these bridges and viaducts and these must be assessed. As the current safety codes...

This report will treat the use of models to predict discoloured water events. Discoloured water events happen when sediment in drinking water pipes is resuspended. This can lead to (brown coloured) sediment coming from the consumer's tap. As this is not desirable, models have been developed to predict these occurrences.

Haptic shared control (HSC) is a method to combine the abilities of humans and machines, in which human and automation jointly exert forces on an input device. According to human-centered design, the underlying controller for HSC should closely resemble human behavior. This paper aims to continuously adapt HSC based on an online identified...

Conventional computer programs based on radiation-diffraction theory are not able to predict the motions of a semi-submersible crane vessel in case the pontoons are only slightly submerged. Cause of the erroneous results are non-linearities like breaking waves on top of the pontoons and emergence of the pontoons itself. Objective of this thesis...

Many breakwater projects start with the selection phase which consists of the consideration of alternatives. These breakwaters are required to protect ports, banks and habitat areas from significant wave action. Moreover, upcoming Design & Construct contracts drive contractors to perform the consideration of alternatives and design themselves....

Drifters equipped with GPS-trackers have been widely used to investigate surface velocities in a wide range of coastal and oceanic settings. A detailed description of a new, cell-phone based, budget drifter system is given, along with an overview of the potential error sources and the magnitude of these sources. Drag related “windage” errors...

Some consultants within KPMG advisory feel like the services that KPMG advisory generates for its clients, could be improved. They see a potential solution within the application of design activities related to design paradigms such as user experience and customer experience. However several hurdles are experienced within the introduction of...

A production process developed to produce tin-bismuth alloy shot particles directly out o f the liquid metal phase, appeared difficult to be controlled. Therefore, within this graduation project, the underlying physical principles o f droplet formation and the process parameters had to be characterised. After characterisation of the process...

In this MSc thesis it is investigated how the first version of concrete armour unit Xbloc+, Xbloc+ v1, acquires its stability. The stability mechanisms are investigated by conducting two type of physical model tests. First, 23 dry pull-out tests are done to obtain insights into the aspects and mechanisms that influence the...

This thesis presents the use of a new class of flight control actuators employing Post-Buckled Precompressed (PBP) piezoelectric elements in morphing wing Uninhabited Aerial Vehicles (UAVs). The new actuator relies on axial compression to amplify deflections and control forces simultaneously. Two designs employing morphing wing panels based on...

Spatial planning is, foremost, regarded as a political method to influence the geographic distribution of activities. The Netherlands has a strong tradition in spatial planning. The national government has put great efforts to direct the spatial developments and to control the urbanization process in the Netherlands, though the existing planning...

Attitude determination and control is the estimation of the current orientation of a satellite and controlling or changing it in order to reach a desired orientation. In the current gener- ation of nano satellites an Attitude Determination and Control Subsytem (ADCS) plays an important roll and sometimes even critical roll. An ADCS is necessary...

Er wordt uitgegaan van het aangegeven voorkeurstracé. Er wordt geen aandacht besteedt aan een eventueel alternatief tracé. Het project wordt beperkt tot het ontwerp van een alternatieve aanleg voor lange baanvakken, inclusief de bijbehorende kunstwerken. Speciale kunstwerken ter plaatse van kruisingen met rivieren en kanalen worden niet nader...

I attended a double-degree master program at the Delft University of Technology (DUT). That means that I combined two master programs, namely Science Education and Communication (SEC) and Strategic Product Design (SPD), into one program. This double-degree program required me to integrate the graduation projects of both masters into one...
