This report presents a new filter wheel design for use in space-based optical systems. The design integrates a hybrid linear stepper motor into the wheel's rim to generate rotation, leading to a Rotating Hybrid Linear Stepper Motor (RHLSM). Unpowered this motor generates a holding force that can keep the wheel in position during system...

For large-scale system with tens of thousands of states and outputs the computation in the conventional Kalman filter becomes time-consuming such that Kalman filtering in large-scale real-time application is practically infeasible. A possible mathematical framework to lift the curse of dimensionality is to lift the problem in higher dimensions...

Recently, the application of machine learning and data fusion techniques on hyperspectral imagery have demonstrated potential for ground cover classification at material level. Hereby, specific locations of resources enclosed in cities (e.g. roof materials) can be identified, which is critically relevant within the field of urban mining. A...

In many engineering fields it is beneficial to obtain information about the force acting on a dynamical system. As measurement of this force is often difficult or impossible a technique that identifies this force in an alternative manner is desired. A wide variety of methods is available in literature. Obtaining this force in the frequency...

At virtually every public venue, announcements for visitors are made via a public addressing system. It is important that announcements transmitted by means of a public addressing system are not only audible, but also well understood by the general public. This thesis covers one of three subsystems required to make
a product that is capable...

Recent advances in sensor technology have lead to increased resolution of novel sensors, while tracking applications where distance between sensors and objects of interest is very small have gained research interest recently. In these cases, it is possible that multiple sensor detections are generated by each object of interest. Extended Object...

In this thesis, the design and implementation of an improved current controller for grid-tied converters is discussed. Using this improved current controller, a power factor correction test platform achieves practically zero AC and DC error in steady-state. The power factor corrector accomplishes this by utilizing the parallel combination of a...

‘Phytoremediation is the use of plants and their associated microbes for environmental clean-up’(Pilon-Smits, 2005). It is a natural, passive and efficient way of cleaning contaminated soil, water, and air. Every year, there are reports of contamination of swimmers due to the contaminated canal water round the Marineterrein in Amsterdam. The...

Pose estimation through fusion of GNSS with secondary sensors has long been an established field. With the developments surrounding autonomous navigation over the past decade this topic has gained extra importance. In the current literature GNSS based pose and localisation is often improved through fusion with either a IMU}or VS with the goal of...

To aid in the continued effort of making unmanned flight safer, this paper presents the experimenting effort towards determining aerodynamic forces on a off-the-shelf quad-rotor under compromised circumstances. For the first time an Incremented Nonlinear Dynamic Inversion controller is used for compromised flight in wind tunnel conditions. For...

Many processes rely on the availability of the Internet. The Border Gateway Protocol (BGP) is widely used for exchanging routing information between routers and is essential for the successful operation of the Internet. Because BGP has not been designed with security in mind, BGP anomalies such as origin hijacks, route leaks, and link failure...

This research is focused on the feasibility assessment of a novel technology of metasurfaces in order to design a spectropolarimeter with the thickness of a few micrometers integrated on the detector array. The motivation behind the research is miniaturization of state-of-the-art spectropolarimeters. The requirements for the instrument are...

Spreading processes are ubiquitous in nature and societies, e.g. spreading of diseases and computer virus, propagation of messages, and activation of neurons. Computer viruses cause an enormous economic loss. Moreover, many illnesses/diseases still causing a serious threat to public health. For example, the outbreaks of circulating influenza...

Over the past years, the automotive industry has seen a constantly increasing level of automation of automotive vehicles. This increasing level of automation contributes to an increasing safety in traffic and a reduction of traffic congestions due tio faster response times and higher reliability, with respect to the human driver. The automation...

Current Ballistic Missile (BM) defence systems intercept an incoming threat in its terminal phase, and to some extend during its coast phase. During the boost phase of a BM, the initial velocity of the BM is low and the hot exhaust plume is easy to spot for infrared sensors, which provides a good opportunity for interception. To do so, the...

Building Integrated Photovoltaics (BIPV) has the potential to play a major role in the ongoing transition towards nearly zero energy buildings. However, the BIPV market is still a niche market, representing only 1% of the global PV share. One of the main barriers that hinder the deployment of BIPV is the lack of aesthetic flexibility. Architects...

Signal Analysis techniques are routinely used in Neuroscience to interpret raw signals harvested from the Nervous System. From a simple Fourier analysis to more complicated methods such as multiresolution wavelet analysis, such techniques must be used for signal manipulation in order to reach informed conclusions on the measurements taking place...
