van Vliet, Sjoerd (author)Different paradigms can be used to evoke brainwaves. These brainwaves can be interpreted as commands that can be used to control different applications. These frameworks that interpret the brainwaves are called brain-computer interfaces. Steady-state visually evoked potentials is one of these paradigms that uses external stimuli flickering at...master thesis 2023

Rong, Richard (author)In recent years, there has been renewed interest in propeller research due to environmental concerns. Propellers are known for their low-speed efficiency and compatibility with electric motors. The utilization of regenerative energy during deceleration has been demonstrated to be beneficial for automobiles and has the potential to be applied to...master thesis 2023

WEI, LAI (author)3-D ultrasound imaging using a 2-D array provides much more information about our body than conventional 2-D imaging. However, due to the large number of elements in a 2-D array, channel count reduction is required and the power and area budget for each element is limited. It is quite challenging to design an ultrasound interface circuit with...master thesis 2023

Liu, X. (author), Xiao, Yuchun (author), Jiang, Huihuang (author), Guo, Y. (author), Yu, Mengwen (author), Tan, Wanzhong (author)This study presents the analogical assessment of the train-induced vibration and radiated noise in a proposed theater. The theater is to be constructed in a region with crowded metro lines, and the assessment is implemented in an analogical building with comparable structural type and metro condition. Prior to the assessment, the comparability...journal article 2023

Zamponi, R. (author), Satcunanathan, S. (author), Moreau, S. (author), Meinke, M. (author), Schröder, W. (author), Schram, C. (author)Integrating a porous material into the structure of an aerofoil constitutes a promising passive strategy for mitigating the noise from turbulence–body interactions that has been extensively explored in the past few decades. When a compact permeable body is considered in the aeroacoustic analogy derived by Curle to predict this noise source, a...journal article 2023

Meloni, S. (author), de Paola, E. (author), Grande, E. (author), Ragni, D. (author), Stoica, L. G. (author), Di Marco, A. (author), Camussi, R. (author)Propeller noise generally exhibits a rich mixture of tonal and broadband components related to different physical mechanisms. Specifically, the tones are characterized by having deterministic and persistent characteristics, while the broadband counterpart has random behaviour. The separation is essential for the experimenters as they provide...journal article 2023

de Jong, M.H.J. (author)This thesis comprises several experiments involving silicon nitride trampoline membranes. These membranes are excellent mechanical resonators and can be fabricated with desirable optical properties. Their dynamical behavior, particularly the interaction of their mechanical motion with light, is of interest for optomechanics and sensing...doctoral thesis 2022

Luesutthiviboon, S. (author)Nowadays, large wind turbines are installed and operated close to densely populated areas due to the growing need for renewable energy. Noise constraints are hampering this development. The most relevant wind turbine noise source is the so-called Turbulent Boundary Layer Trailing-Edge (TBL–TE) noise. Many passive TBL–TE noise reduction...doctoral thesis 2022

Aeroacoustics of Jet-Surface Interaction and Passive Solutions for Mitigating Jet-Installation NoiseRego, Leandro (author)Aircraft noise levels have been significantly reducedwith the introduction of high-bypass ratio turbofan engines, particularly jet noise due to turbulence mixing. This, however, has led to engines with larger diameters and a closer coupling between them and the airframe. As a result, interactions between the exhaust jet flow and the wing give...doctoral thesis 2022

Verkleij, Simon (author)Receivers for millimeter-wave (mm-wave) 5G, with the ability to detect a low-power desired signal, in the vicinity of large power blockers, require highly linear circuitry with a large power consumption. Suppressing the out-of-band blockers reduces this power consumption. N-path filters (NPFs) have recently been used to reject interferers in...master thesis 2022

Vergés i Plaza, Guillem (author)Trailing-edge noise can be the dominant noise source of diverse industrial applications, including wind turbines. Noise regulations may limit the power production and installation of new wind farms. There is a need to reduce it. In order to achieve so, we first need to predict it, and to do so we need experimental data to support and validate...master thesis 2022

Aalberse, Max (author)During the COVID-19 pandemic people living close to the airport got accustomed to less flights, and therefore less noise disturbance. Now the amount of traffic is increasing again and so is the noise disturbance.

van Mourik, Floris (author), Onstein, Teije (author)As electromagnetic waves cannot propagate sufficiently far in water, underwater communication is mainly performed using either acoustics or optics. However, none of these technologies have been proven to be completely effective in every situation. Therefore, research in new underwater communication systems can still bring large benefits to a...bachelor thesis 2022
