De Athayde Costa E Silva, M. (author)
In recent years, there has been an increase in the number of small multi-mission platforms such as CubeSats, in an attempt to reduce costs of space missions. CubeSats have been used for different purposes including Earth observation, research and technology demonstration.
However, a key technology that is still under development is the...

The design of aerodynamic airfoils are optimized for certain conditions. For instance, the shape of the wings of fixed-wing aircrafts are designed and optimized for a certain flight condition (in terms of altitude, speed, aircraft weight, etc.). However, these flight conditions vary significantly during the flight. Currently, aircraft are...

Since the industrial revolution, machines have taken over many tasks from humans, increasing labor productivity and prosperity. In the 20th century, the introduction of robots created a second wave of automation, increasing the labor productivity even further. In order to create a third wave of automation, it is necessary to develop a new...

Every person on the planet lives a significant portion of his or her life in a built indoor environment. Ideally, the built environment serves as protection from the extremes of the outdoor environment and is preferably comfortable. The first ‘built environment’ was a painted cave. The cave served as a shelter and the wall paintings represented...

Classical control theory requires a model to be derived for a system, before any control design can take place. This can be a hard, time-consuming process if the system is complex. Moreover, there is no way of escaping modelling errors. As an alternative approach, there is the possibility of having the system learn a controller by itself while...

Gebraad, P.M.O. (author)
Each wind turbine in a cluster of wind turbines (a wind power plant) can influence the performance of other turbines through the wake that forms downstream of its rotor. The wake has a reduced wind velocity, since the turbine extracts energy from the flow, and the obstruction by the wind turbine rotor causes increased turbulence. If another...

Kuiper, S. (author)
This research is focused on improving the mechatronic design and control strategies of Atomic Force Microscopes (AFM) in order to increase the imaging speed of these instruments, while maintaining the resolution and accuracy of AFM. Different techniques are developed which have led to a faster lateral scanning speed, higher bandwidth control of...

Wesselingh, J. (author)
In the production of integrated circuits, solar cells, flat panel displays and elec- tronics, thin plates are often used as a base for manufacturing. Examples are silicon wafers and glass panels on which several process steps build transistors, pixels and interconnects. To improve the production throughput these features are made smaller while...

Alvarez Cabrera, A.A. (author)
Design activities, including control design, are becoming increasingly difficult due to a corresponding increase in product and product development complexity. Model-based (or driven) engineering, development and design have become common concepts related to modern complex product development practices. However, it is argued here that currently...

Operational management of water resources needs predictions of future behavior of water systems, to anticipate shortage or excess of water in a timely manner. Because the natural systems that are part of the hydrological cycle are complex, the predictions inevitably are subject to considerable uncertainty. Still, definitive decisions about e.g....

Souverein, L.J. (author)
Shock wave boundary layer interactions (SWBLI) are a common phenomenon in transonic and supersonic flows. The presence of shock waves, induced by specific geometrical configurations, causes a rapid increase of the pressure, which can lead to flow separation. Examples of such interactions are found in amongst others rocket engine nozzles and on...

Van Schagen, K.M. (author)
The drinking water in the Netherlands is of high quality and the production cost is low. This is the result of extensive research in the past decades to innovate and optimise the treatment processes. The processes are monitored and operated by motivated and skilled operators and process technologists, which leads to an operator-dependent,...

Schiele, A. (author)
This thesis is the first to provide the fundamentals of ergonomic exoskeleton design. The fundamental theory as well as technology necessary to analyze and develop ergonomic wearable robots interacting with humans is established and validated by experiments and prototypes. The fundamentals are (1) a new theoretical framework for analyzing...

The modern trailing suction hopper dredgers are advanced ships that are equipped with many automation systems that can be controlled with integrated computer systems from the bridge. From the operators it is expected that they generate the right set-points for all these systems. The latest ships are designed such that one operator is responsible...

The objective of this thesis is to create a distributed, multi-agent, approach to traffic control. This PhD thesis' focus is on the control of a network instrumented by traffic signals.A thorough literature study has been performed, reviewing the current state of the art in traffic signal control. On the basis of this literature survey, a...

This thesis aims to investigate how the experience of engagement in interaction can be explained by examining the experiences of richness and control and how these experiences are influenced by the features of a product, the expertise of a person and the type of task. This research is carried out within the domain of digital products. From the...
