ten Klooster, Fons (author)Research in passive Heating, Ventilation, and Air Conditioning (HVAC) systems has gained traction over the last few years. Although passive HVAC is not a new concept, advances in environment sensing, control methods, and hardware have made it a more viable method. Some difficulties still exist, such as optimal sensor placement and optimal...master thesis 2022

van Noppen, Thirza (author)Second-order Gaussian kernels have been utilized to develop three algorithms that could automatically extract ridge lines for hydrodynamic modelling. Isotropic second-order Gaussian kernels produce inaccurate lines at crossings and junctions. To avoid the malfunctioning of Second-order Gaussian kernels, one default and two alternative algorithms...master thesis 2022

Pascual Laguna, A. (author)The mysteries of the early Universe are largely enshrouded in dust, product of the violent process of star formation. Due to the vast distances of our Universe, infrared light emitted by the heated dust back in those early stages can still be observed today, which has been observed to contribute to about half of the total cosmic background...doctoral thesis 2022

Zhang, Chenyan (author)Modern communication systems have a strong need for low-cost and high-stability frequency references. Although low-cost crystal oscillators can easily be realized and are available to the market in large quantities, crystal oscillators with frequency stability in the ppb(10^{-9}) range over a wide temperature range are only available at high...master thesis 2022

Psychas, D.V. (author)Precise Point Positioning (PPP) is a Global Navigation Satellite Systems (GNSS) modelling and processing method that provides single-receiver users with high positioning accuracy anywhere on the globe, without the explicit dependence on reference receivers. The realization of PPP is based on undifferenced code and phase measurements, a priori...doctoral thesis 2022

den Boer, Dirk (author)Accurate vehicle localization is considered to be a key element in future automated driving systems. A network of multiple sensors is employed to deliver information for this localization process. Loosely coupled integration of global navigation satellite systems (GNSS) and inertial navigation systems (INS) data is a common sensor-fusion method...master thesis 2022

Lengkeek, Robert (author)This study investigates the use of an open filter in a land reclamation structure. The possibility of replacing the geotextile that secures the core-backfill interface with a granular filter has been investigated. This is easier to install and therefore a potential cost-saving. Experiments have been done to determine the influence of various...master thesis 2022

Cornejo Ramirez, Cesar Eduardo (author)Background and Objectives: Wearable devices (WDs) capable of recording electrocardiograms (ECGs) for prolonged periods in ambulatory settings offer the possibility of detecting non-predictable events such as epileptic seizures and atrial fibrillation. Nevertheless, these systems suffer from additional noise sources, such as movement artifacts ...master thesis 2022

Choi, Woojun (author), Angevare, J. (author), Park, Injun (author), Makinwa, K.A.A. (author), Chae, Youngcheol (author)This article presents an energy-efficient dual- RC frequency reference intended for wireless sensor nodes. It consists of a digital frequency-locked loop (FLL) in which the frequency of a digitally controlled oscillator (DCO) is locked to a temperature-independent phase shift derived from two different RC poly-phase filters (PPFs). Phase...journal article 2022

Odriozola, Magela (author), van Lier, J.B. (author), Spanjers, H. (author)Flux enhancers (FEs) have been successfully applied for fouling mitigation in membrane bioreactors. However, more research is needed to compare and optimise different dosing strategies to improve the filtration performance, while minimising the use of FEs and preventing overdosing. Therefore, the goal of this research is to develop an...journal article 2022

Zhang, H. (author), Berkhout, Marco (author), Makinwa, K.A.A. (author), Fan, Q. (author)Class-D audio amplifiers produce electromagnetic interference (EMI), which often needs to be suppressed by an external LC filter. However, due to component nonlinearity, this filter can itself cause significant distortion. This article presents a class-D amplifier that suppresses LC filter nonlinearity by 49 dB and is robust to ±30%...journal article 2022
