Simoes dos Santos, D. (author), Baldini, L.B. (author), Vos, H.J. (author), Verweij, M.D. (author), de Jong, N. (author), van Neer, P.L.M.J. (author)The accurate determination of the transfer function of ultrasound transducers is important for their design and operational performance. However, conventional methods for quantifying the transfer function, such as hydrophone measurements, radiation force balance, and pulse-echo measurements, are costly and complex due to specialized equipment...journal article 2024

Hernandez Quintanilla, Tomás (author)Similarity joins are operations which involve identifying similar pairs of records within one or multiple datasets. These operations are typically time-sensitive, as timely identification of relations can lead to increased profitability. Therefore, it is advantageous to analyze them using a stream processing system, which offers real-time...master thesis 2023

van Ruiten, Joséphine (author)Globally, drinking water sources are polluted with poly- and perfluoroalkyl substances (PFAS). The toxicity and persistent properties of these industrial chemicals raised concerns about environmental and public health. As a result, drinking water companies are removing PFAS from drinking water using separation technologies. Anion exchange and...master thesis 2023

Găleşanu, Matei (author)Neural Radiance Fields (NeRF) and their adaptations are known to be computationally intensive during both the training and the evaluating stages. Despite being the end goal, directly rendering a full-resolution representation of the scene is not necessary and not very practical for scenarios like streamed applications. Our goal is to design a...bachelor thesis 2023

Kanis, Job (author)The introduction of cloud hosting has made it possible to elastically provision distributed stream processing systems (SPEs). By dynamically scaling the different operators of the system, resource consumption can be minimised while meeting the system service-level objectives. In the literature, many different auto-scaling techniques are proposed...master thesis 2023

Jongbloed, Sanne (author), Lebbink, Pepijn (author), Pap, David (author), Dingeldein, Quintus (author)There exists no general method for analysing the efficiency of a shipyard layout through the mapping of building processes and employee movements. Therefore an Integrated Method for mapping shipyard layouts is developed. This is done by implementing multiple ways of analysing and optimising industrial processes, as found in the literature. Usage...bachelor thesis 2023

Kanniainen, Konsta (author)Various techniques have been studied to handle unexpected changes in data streams, a phenomenon called concept drift. When the incoming data is not labeled and the labels are also not obtainable with a reasonable effort, detecting these drifts becomes less trivial. This study evaluates how well two data distribution based label-independent drift...bachelor thesis 2023
