Boersma, Floris (author)This thesis is the third study of a research line that focuses on the interface stability of a rubble mound sand retaining structure. The type of interface considered is a geometrically open granular filter because of its economical and constructional benefits. The stability of an open filter structure in which the base layer is located on top...master thesis 2020

Pocchiari, M. (author)Recommender Systems assist the user by suggesting items to be consumed based on the user's history. The topic of diversity in recommendation gained momentum in recent years as additional criterion besides recommendation accuracy, to improve user satisfaction. Accuracy and diversity in recommender systems coexist in a delicate trade-off due to...master thesis 2020

Lucassen, Max (author)Least-squares support-vector-machines are a frequently used supervised learning method for nonlinear regression and classification. The method can be implemented by solving either its primal problem or dual problem. In the dual problem a linear system needs to be solved, yet for large-scale problems this can be impractical as current methods...master thesis 2020

Agarwal, Gayatri (author)MRI machine has evolved tremendously over the years from its inception in order to render high-quality 3D images, best among its companion imaging systems. Of the whole system, RF receiver is the most crucial for its noise performance, which is expected to provide high SNR at all operating conditions. At Philips, MRI’s RF receiver is based on...master thesis 2020

Žnidaršič, L.Y.D. (author)A fundamental task of intelligent and autonomous robots is to infer from observations the state of the world. This inference is generally achieved by employing a filter, which consists of a model and filtering law. Learning this model and filtering law from observations is another fundamental part of robotics, and is generally referred to as...master thesis 2020

van der Voort, J.C. (author)The goal of this thesis is to estimate parameters in a bidimensional Ornstein-Uhlenbeck process, namely a diffusion model which can be found in Favetto and Samson (2010), which considers plasma and interstitium concentrations. We first look at a general linear stochastic differential equation and some properties. Then we simulate possible paths...bachelor thesis 2020

Goudsmit, L. (author)In the ocean resides a large amount of plastic. This has severe environmental consequences for the oceans. To be able to clean up all this plastic the location of the plastic is needed. A lot of times plastic is cleaned up at the source, but to clean up here this location needs to be known. However, what if the start location is not known and...bachelor thesis 2020

Bakos, Máté (author)In the field of biomedical imaging, images often report a combination of biologically induced variation, usually the goal of the imaging process (e.g. outlining an anatomical region or disease pattern), and non-biological variation, such as instrument or acquisition method-induced noise patterns. <br/>Since some medical decisions are made based...master thesis 2020

Frantzi, Georgia (author)Building energy consumption is one of the highest of any sector. Building integrated Photovoltaics (BIPV) have the potential to eventually contribute to 50%-70% of the total energy demand. However, one of the main barriers that hinder the acceptance of solar energy systems as an integrated part in the buildings’ envelope is the limited...master thesis 2020

de Rooij, S.J.S. (author)In streaming video completion one aims to fill in missing pixels in streaming video data. This is a problem that naturally arises in the context of surveillance videos. Since these are streaming videos, they must be completed online and in real-time. This makes the streaming video completion problem significantly more difficult than the related...master thesis 2020

Huijten, Esmee (author)Ultra-wideband submillimeter observations are crucial to study the process of star and galaxy formation and for characterizing cosmic dust in the interstellar medium. The Deep Spectroscopic High-redshift Mapper 2.0 (DESHIMA 2.0) will use an integrated superconducting spectrometer chip with a 220-440 GHz band coverage and a spectral resolution of...bachelor thesis 2020

Huijbregts, L.C.A. (author), Jongepier, M.A. (author)Public Address systems that include a setup with at least one microphone and speaker can suffer from acoustic feedback. This results in an annoying howling effect which can damage hardware and human hearing. To solve this issue, an adaptive filter that estimates the feedback path and uses this estimate to cancel the feedback can be designed....bachelor thesis 2020

Weustink, C.A. (author), de Vries, J.W. (author)The most promising method for acoustic feedback control in public address systems is adaptive feedback cancellation (AFC). This approach is based on making an estimation of the room impulse response, which is used to subtract an estimate of the feedback from the microphone signal. A postfilter is often used to improve the performance of such an...bachelor thesis 2020

Meyer, J.W.D. (author), de Ronde, F.W.M. (author)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...bachelor thesis 2020

Bode, Danielle (author)Predictions of the morphology of coastal areas are used to make decisions on coastal defence and nature conservation. To predict this morphology, simulations made by morphological models are used. To base decisions on this morphology predictions, we want the uncertainties in these predictions to be small. The goal of this research is to get a...master thesis 2020

Vertregt, Casper (author)This research applied a Dual Extended Kalman Filter (DEKF) to time-varying human operator (HO) parameter estimation in preview tracking tasks. The preview time parameter was of particular interest, as the amount of preview can be highly variable in practical situations. The filter was centered around a linear cybernetic HO model with six...master thesis 2020
