Permanent Magnet Synchronous Machine have found their way into more applications due to their high power and torque density and high efficiency. The PWM schemes used to generate the voltage signals for the machine consist of high frequency trapezoidal signals, when not filtered. These high frequency signals when directly applied to the machine...

Every year an unfortunate part of the population lose their larynx, often due to the consequences of cancer. The laryngectomy removes the possibility to speak. Fortunately several speech reinstatement techniques have been found. However, all current speech reinstatement techniques do not produce a lot of volume. As a result the laryngectomised...

Due to a high contribution of human error in fatal traffic accidents, efforts in research and industry for automating vehicles steadily increased the last 3 decades. To reduce accidents with other road users, automated recognition and classification of road users is crucial. The most accurate models are large convolutional neural networks,...

This study discusses the filtration of micro-pollutants and natural organic matter<br/>from water by a granular activated carbon filter. To determine the efficiency of a<br/>filter, simulations are run to predict it’s efficiency. This study will describe a demo application and it’s underlying model that are used to determine the efficiency of a...

Despite large scale application of performance- and risk management practices, project organisations struggle with responding adequately to early warning signs of project problems. This research investigates the main barriers in responding to early warning signs, and provides recommendations on how to deal with them, in order to stimulate the...

Developing parallel applications to make efficient use of current and emerging parallel architectures remains a big challenge in modern application development where performance is a first-class citizen. Optimizing conventional video filter applications to take advantage of current multi- and many-core architectures is one such application. This...

Path tracing has been successfully utilized in modern animated films to produce photorealistic images. However, with path tracing being a Monte Carlo method, a large amount of light paths must be sampled to reduce image noise to acceptable levels. Although a wide variety of acceleration and importance sampling techniques have been developed to...

Wind power as a green and low-carbon renewable energy could effectively mitigate the energy crisis and reduce environmental pollution, including the rapid developing offshore wind power with its rich reserves, wind stability, high wind speed, less interference, noise and other advantages. The trend for development of offshore wind farms is...

Current trailers and caravans use overrun brakes, which cause overheated brakes in the mountains. A solution is to design an electric brake system in which the brakes are controlled electronically instead of mechanically. The report discusses the control models associated with braking, anti-sway detection and velocity sensor fusion. The RDW...

In the world of DC railway trains nowadays, asynchronous-traction machine with traction controllers, i.e. an inverter with variable output frequency, is implemented. This controller changes the incoming DC voltage into an AC voltage of a variable frequency and RMS amplitude. The disadvantages of switching inverters, compared to a pure sine wave...

In Nicaragua, active research for arsenic started in 1996, after the first case of arsenic poisoning was reported in a rural community. Arsenic concentrations present in drinking water cause chronic poisoning, which depending on the exposure, lead to several life-threatening long term effects. It is however unknown to what extent this...

The steadily growing amount of orbital debris increases the probability and amount of collisions between two objects in orbit about the Earth. These collisions in turn create even more debris, and it is therefore important to keep track of future conjunctions. The U.S. Space Surveillance Network (SSN) uses ground- and space-based sensors to...

In this thesis, a UWB pulse generator is designed to be implemented in IBM 0.13 um technology. The pulse generator has a high spectral efficiency. Using amplitude control, any mismatch, process variation or temperature variation can be compensated for to comply with the UWB FCC mask. The pulse has an approximate duration of 2ns. The current...

Filterconstructies hebben als doel erosie te voorkomen in bepaalde delen van waterbouwkundige kunstwerken. Ze zijn opgebouwd uit een basislaag en een of meer filterlagen. Er zijn verschillende soorten filterconstructies. Ze worden over het algemeen zo gemaakt dat er geen erosie zal optreden van basismateriaal. Het is echter efficienter om een...

In de kust- en waterbouw worden regelmatig geometrisch open filterconstructies toegepast. Er bestaat onduidelijkheid over het doordringen van de hydraulische be lasting in de filterlaag en de invloed daarvan op de erosie van de basislaag. Eerder onderzoek geeft het verband aan tussen de schuifspanning op de filterlaag en schuifspanning op de...

In rivieren en kanalen worden bodembeschermingen toegepast om te voorkomen dat stromingen ontoelaatbare ontgrondingen veroorzaken. Naast natuurlijke stromingen in de rivier veroorzaken scheepsgeïnduceerde waterbewegingen deze stromingen. Een bodembescherming be staat meestal uit een toplaag met daaronder een of meer filters. De toplaag moet...
