Currently the production process of acoustic guitar factories does not result in instruments with equal dynamical behaviour, due to the varying material properties of wood from tree to tree. Experienced individual guitar builders are able to handle those material variations, but this is a labour intensive process because there is no structured...

Ice skating is (still) very popular in the Netherlands, and it is gaining popularity across the globe. Temporary ice rinks on squares and in parks is an increasing solution in order to attract visitors in the winter and holiday season. Ice-World International, the world leader in temporary ice rinks since 1992, has experienced a significant...

Multi model adaptive control is an emerging field that has proven to be successful in mitigating limitations of classical adaptive control by providing more quicker and faster adaptation. In this method instead of one single parameter varying controller, multiple fixed parameter controllers pertaining to different operation regimes are utilized....

The goal of this thesis is to present a framework which can be used to optimize the observer and controller performance by placement of sensors and actuators on a continuous domain. The framework provides choices of model structure, cost functions and optimization methods to perform the placement. Systems which would be suitable for the use of...

This thesis concerns research into the parametric modelling and optimization of steel-concrete bridge typologies typically found in the Netherlands, in order to further the automation of preliminary bridge designs. The research question posed is: "How can a parametric bridge design model be composed to fit into the <br/>overall road design...

Lyapunov's 2nd method can be formulated as a convex optimization problem by means of Sum-of-Squares (SOS) optimization. This gives a powerful tool for robust stability analysis of nonlinear systems. The use of SOS optimization is limited to small dynamical systems, because of the demanding numerical complexity underlying SOS optimization. For...

In order to reduce the climate impact induced by the aircraft industry, the variability between cost optimized and climate optimized flight trajectories was evaluated. This was done to establish how the climate impact reduction affects the operating costs and vice versa. To evaluate the climate impact of air traffic, a climate-chemistry model...

In the noiseless case, the identification of a grey-box model can be posed as a feasibility problem, i.e. determining if existent - and if so - finding a parameter vector such that the parametric model equals the actual model (or its associated input-output data). Being that in this thesis we are interested in continuous-time grey-box...

The area surveillance problem is the problem of surveying a known or an unknown area with the main purpose of detecting objects. This thesis will tackle the problem of how to employ a group of mobile-sensors for surveying an unobstructed area in an optimal manner. The mobile-sensors should make use of their onboard computers and they should...

Tensegrity is a structural form that is defined as a set of rigid elements suspended in a net of continuous tension. This structure shows potential for compliance, impact tolerance and mechanical robustness. However, its non-linear coupled dynamics and often complex geometry require advanced control strategies. An actuator reference planning...

The current situation with green gas emission requires the development of low carbon energy solutions. However, a significant part of the modern energy industry still relies on fossil fuels. To combine these two contradictory targets, we investigate a strategy based on a combination of CO2 sequestration with Enhanced Oil Recovery (EOR) in the...

Nowadays space missions rely heavily on optical payloads to carry out a wide range of tasks including earth observation, weather monitoring, astrophysics research and communications. Until recently, the design of such systems was done according to design principles such as rotational symmetry as it simplifies the theory, reduces technological...

Vessels are becoming more and more optimized towards their mission and an increasing amount of systems are considered during this optimization. Most of these considerations occur at an early design stage, where data is scarce and their impact is large. <br/>This research aims to aid designers in considering this growing forest of possible system...

The Netherlands policy on electricity steers towards a carbon neutral power generation in 2050. Among<br/>the studies that focus on long term power system research, none use the starting point of a 100%<br/>renewable power system in 2050. It is unknown if such a system is technically feasible given the<br/>variability of wind and solar. The...

Population growth, meat-focused diets and emerging industries are increasing stress on water, energy and food (hereafter: WEF) supply around the globe. As stress on the resources rises, the interdependencies between the sectors become more apparent and often lead to unforeseen chain reactions. An example of which is: a drought leads to...
