Determining the magnitude of particular fault signature components (FSCs) generated by wind turbine (WT) faults from current signals has been used as an effective way to detect early abnormalities. However, the WT current signals are time varying due to the constantly varying generator speed. The WT frequently operates with the generator close...

Human interaction with a smart speaker involves often distant automatic speech recognition (ASR). However, ASR is a rather cumbersome task at significantly high levels of noise. Most of commercial smart speakers in order to achieve high ASR accuracy they tend to reduce the playback signal once the preset keyword is detected. In an effort to...

The thesis project is aimed at designing an unobtrusive method to find the obstruction location and severity for patients who are not diagnosed with Obstructive sleep apnea, during their non-sedated sleep using simple recording devices within uncontrolled environment. Similar to speech generation, which is enabled by opening and closing of the...

In research, the overall power production in a wind farm is typically increased by employing model-based wind farm control. A controller, in an open-loop setting, operates based on the velocity of the wind flow, predicted by a wind farm model. For a controller to achieve the desired level of power production, a wind farm model has to be accurate...

This thesis presents the design and implementation of a low power 3rd-order loop filter and a low power, compact, high-speed inverter-based amplifier designed in 28nm HPC for a GHz sampling Σ∆ modulator.
In the earlier design, the size of the pMOS in an inverter was found to be nine times larger than the nMOS which is not practical to obtain a...

Objective: Estimators to accurately monitor ventricular relaxation, cardiac contractility and cardiac output (CO) during support of a left ventricular assist device (LVAD), based on the left ventricular pressure (LVP) and pump-intrinsic signals, were developed. The aim was to continuously monitor these cardiac parameters, hereby tracking the...

In recent years, personalized recommender systems have been facing criticism in research due to their ability to trap users in their circle of choices, called "filter-bubble", thereby limiting their exposure to novel content. In solving the issue of filter-bubble, past research has focused on providing explanations to users about how a...

The detection of unusual behavior plays a crucial role in the prevention of illegal and harmful activities such as smuggling, piracy, arms trading, human trafficking and illegal immigration. Also for military applications, it is useful to detect anomalous behavior to provide an alert for potential threats, especially with the more recent...

In this paper we consider the problem of State Estimation (SE) in large-scale, 3-phase coupled, unbalanced distribution systems. More specifically, we address the problem of including mixed real-time measurements, synchronized and unsynchronized, from phasor measurement units and smart meters, into existing SE solutions. We propose a...

Vibration-based structural health monitoring of civil engineering structures is receiving increasing attention in recent years. This is due to the development of more robust system identification techniques as well as improvements with regard to the practicality of installing the necessary instrumentation. Health monitoring systems are more...

The formation of scour holes is a vital thread of retaining the water infrastructure of rivers. Nowadays, protective filters are used to prevent washing away of the underlying material. Rijkswaterstaat started the program 'Stroomlijn’, in which trees (logs) are cut from the floodplains and placed in a sheltered zone of the river to test whether...

When the re brigade arrives at a burning building, it is of vital importance that people who are still inside can quickly be found. In this thesis we contribute to an ultrasonic sound sensor for human presence detection in smoke-lled spaces. This type of sensor could assist the re brigade when evacuating a large building by directing them to the...

The Wien filter is an important part in the multi-beam inspection microscope that is being developed at the Imaging Physics research group at the TU Delft. The multi-beam inspection microscope uses an array of 20x20 parallel beams with a pitch of 1mmthat scan the sample simultaneously. This way the low throughput of current scanning electron...

Zoetermeer is facing two challenges currently. The first is a housing program which is defined only at a superficial level. Secondly, the municipality has expressed the ambition to also take into account the migration of households, but has no data on which dwellings facilitate migrations the best. This research thus set out to first define the...

Numerical predictions of the dynamic response of complex structures are often uncertain due to uncertainties inherited from the assumed load effects. Inverse methods can estimate the true dynamic response of a structure through system inversion, combining measured acceleration data with a system model. This article presents a case study of...

With trajectory data, a complete microscopic and macroscopic picture of traffic flow operations can be obtained. However, trajectory data are difficult to observe over large spatiotemporal regions—particularly in urban contexts—due to practical, technical and financial constraints. The next best thing is to estimate plausible trajectories...

This research is aimed at breaking online political filter bubbles. We present a system that uses artificial intelligence and human computation to automatically collect article metadata on political content and thereby enables diverse personalization on content-serving platforms. This way, exploring alternative viewpoints could become as simple...

Flooding in cities, known as Urban Pluvial Flooding (UPF), causes disruption of society, damage to cities and inconvenience for people. Cities are expected to become more vulnerable to UPF due to more frequent and more intense extreme rainfall events with high spatial variability as result of climate change. Additionally increasing urbanisation...
