Struijk, Victor (author)Life at low-Reynolds numbers regime is intriguing. Single motile bacteria are known to exhibit erratic behaviour; they swim in what is known as a random walk, alternating between periods of swimming straight and abrupt moments of re-orientation. Yet in dense populations, cells of E.coli have been reported to exhibit weak synchronization and self...master thesis 2023

Ottenheym, Joris (author)The placement of wind turbines in wind farms is economically beneficial to the industry. Consequently, the wake generated by the upstream turbines introduces interactions with downstream turbines that significantly affect power generation. However, it is common practice to control the individual turbines to operate at their optimal settings and...master thesis 2023

Rijkeboer, Mats (author)Highly accurate time sources, such as Cesium-based or GPS clocks, are the best candidates to provide a correct notion of time, but are too costly and impractical for implementation in every modern digital device. Ubiquitously, (crystal) oscillators are employed instead. To maintain a shared notion of time, the offsets and drift/jitter have to be...master thesis 2023

Waegenaere, Victor (author)Real-time (RT) systems are widespread over different industries, e.g., healthcare, robotics, manufacturing, machine vision, etc. These systems consist of a hardware and software part that execute an RT application. These systems require a bounded and predictable time response on incoming events and execute all input and output (IO) tasks...master thesis 2022

van Wageningen, Noortje (author)his thesis aims to investigate the change in frequency performance of the Nordic Power System in 2030 caused by the replacement of synchronous generation by NSG. To do this, the Nordic Power System is modeled in the simulation software DIgSILENT PowerFactory 2022 SP1 for modeling and simulation. For the Nordic Power system, periods of low demand...master thesis 2022

Kotsis, Kosta (author)Based on a research conducted by the Civil Aviation Organization, by the year 2050 the emissions of aviation are expected to be 7 to 10 times higher than the levels in the beginning of the century. This will result in the emissions of CO2 from the aviation industry alone, to be higher than what the entire transportation industry is allowed for,...master thesis 2021

Manjunath, Tanmay (author)Advanced automotive vehicles are based on the real-time fusion of an increasing number of automotive sensors. For precise fusion of different sensors, measurements need to be synchronized both temporally and spatially. This thesis aims to design a hardware temporal synchronization block as part of the PRISTINE systolic array accelerator project...master thesis 2021

Abel, Felix (author)In this thesis, we propose a new class of pairwise frequency, multi-domain time synchronization and ranging algorithms for anchorless mobile networks of asynchronous nodes. We apply these techniques and study network and mission level aspects of time synchronization to Orbiting Low Frequency Array for Radio astronomy (OLFAR), a proposed...master thesis 2021

van der Velden, Joram (author)This work proposes an energy harvesting platform that is able to convert power from both DC sources (photo-voltaic cells and TEGs) as well as piezo element sources. It does so only using a single input channel to which a single harvester can be connected. The proposed system is able to differentiate between the two source...master thesis 2021

Gutierrez Prieto, Eduardo (author)Eukaryotic cilia and flagella are some of the best conserved biological structures across species. Giventhe pressure natural selection imposes onto living beings to optimize their body plans, eukaryotic flagella have demonstrated to be an optimal organelle for propulsion at low Reynolds numbers. Therefore, understanding how cilia beat is of...master thesis 2021

Stam, Mariëlle (author)Deep brain stimulation (DBS) is used to treat a variety of movement disorders. In current DBS therapy, the stimulation parameters are manually adjusted based on a subjective assessment of patient’s symptoms. State-of-the-art DBS research focuses on recording brain activity to create a patient-specific neuronal profile that correlates with the...master thesis 2021

Schild, Maarten (author)Due to ever increasing accessibility, recent years have seen a fast growing number of launches to space, especially to Sun-synchronous orbit. The spent rocket parts, payload fairings and eventually non-functioning payloads of these launches remain in orbit. It is well-established that this accumulation of space debris over time is quickly making...master thesis 2021

Buijs, Laurens (author)This thesis is focused on Wireless Acoustic Sensor Networks (WASNs) used for beamforming in a speech enhancement task. Since each node in a WASN has its own clock, clock offsets and clock skews between the nodes are inevitable. Clock offsets and clock skew can be detrimental to the beamformer performance. In this thesis we focus on the effect of...master thesis 2020

Dimopoulos, Giorgos (author)During the last three decades, the Earth’s climate is changing rapidly, with higher average temperatures every year that leads not only to the melting of the ice sheet in the arctic and on most of the glaciers all over the world but also to extreme weather phenomena. The rise of the temperature can affect the Sea Surface Height (SSH) in more...master thesis 2019

Veera Kumar, Nidarshan (author)Until recent times, electrical power grids have been dominated by conventional power plants run by fossil or nuclear fuels in order to cater to the electrical load demand. These power plants employ large generators that operate in synchronous with each other to maintain a stable frequency and voltage across the power grid. The frequency and...master thesis 2019
