Katkam, Rohan (author)The current wireless networks can face congestion issues due to the increasing number of digital devices. One way to overcome this is to establish communica-tion at a different range of frequencies, specifically in visible light. Most studies in Visible Light Communication (VLC) systems use active light sources like LEDs for transmission, but...master thesis 2023

Jose, Nikhil (author)Surfaces that induce slip at the wall have been shown to reduce skin friction drag in the turbulent regime. While superhydrophobic and liquid-infused surfaces are capable of drag reduction in turbulent hydrodynamic flows, neither would be feasible in aerodynamic applications due to the added roughness and the minuscule slip lengths created by...master thesis 2023

Wu, Yike (author)Background: Kidney failure, also called end-stage renal disease, means the kidney has lost its function to remove waste from the blood. Patients with kidney failure usually need hemodialysis, which uses a machine to replace the function of a healthy kidney, to keep them alive and prolong their lives. In order to begin hemodialysis, it is crucial...master thesis 2023

Mulders, Elke (author)The combination of the monumental building, the Rotonde, and the panoramic painting ‘Panorama Mesdag’ is one of the few remaining exhibitions of its kind. The organization of the museum aims to preserve the building and painting while also wanting to decrease the carbon footprint of the museum. The objective of this research is to design a...master thesis 2023

Yang, G. (author), Gram, Remon (author), Procel Moya, P.A. (author), Han, C. (author), Yao, Z. (author), Singh, M. (author), Zhao, Y. (author), Mazzarella, L. (author), Zeman, M. (author), Isabella, O. (author)Passivating contacts based on poly-Si have enabled record-high c-Si solar cell efficiencies due to their excellent surface passivation quality and carrier selectivity. The eventual existence of pinholes within the ultra-thin SiOx layer is one of the key factors for carrier collection, beside the tunneling mechanism. However, pinholes are usually...journal article 2023

Michailidou, E. (author), Visser, P. (author), Mol, J.M.C. (author), Kosari, A. (author), Terryn, H.A. (author), Baert, K. (author), Gonzalez Garcia, Y. (author)The corrosion inhibiting effect of lithium carbonate has been studied over the pH range relevant for atmospheric corrosion conditions at the polymer/metal interface. It is demonstrated that lithium carbonate offers optimum corrosion protection under moderately alkaline conditions attributed to the formation of a protective layer identified as...journal article 2023

van den Engel, P.J.W. (author), Malin, Michael (author), Venkatesh, Nikhilesh Kodur (author), de Araujo Passos, L.A. (author)This research evaluates the performance of a Phase Change Material (PCM) battery integrated into the climate system of a new transparent meeting center. The main research questions are: a. “Can the performance of the battery be calculated?” and b. “Can the battery reduce the heating and cooling energy demand in a significant way?” The first...journal article 2023

Li, Chutian (author), Lai, F. (author), Shiau, Jim (author), Keawsawasvong, Suraparb (author), Huang, Hanhui (author)A narrow backfill zone is formed when retaining walls are built near existing stabilized structures (e.g., rock faces). In such circumstances, the classical passive earth pressure coefficient is no longer applicable, and a correction factor is required for the design. This paper aims to develop analytical solutions for estimating the passive...journal article 2023

de Araujo Passos, L.A. (author), Ceha, T.J. (author), Baldi, S. (author), De Schutter, B.H.K. (author)Controlling the operation of HVAC (Heating, Ventilation, and Air-Conditioning) systems is arguably the most effective way to reach desired indoor conditions in buildings. Nevertheless, such control may involve complex dynamics when dealing with passive energy technologies. In this paper, we focus on maximizing the passive operation of HVAC in...journal article 2023

Kouwenhoven, Timo (author)A novel nonlinear stiffness unit cell aided magnetic gravity compensator is proposed for the purpose of isolating low-frequency vibrations. A negative stiffness magnet setup is combined with a compliant unit cell with tailored nonlinear force-displacement characteristics. This combination offers a large range of motion featuring low stiffness, a...master thesis 2022

van der Staaij, Jasper (author)An intracranial aneurysm is a bulge in the cerebral vasculature. The rupture of an aneurysm results in a brain bleed. As a consequence, most patients become severely handicapped or may even die. Preventive treatment with endovascular coiling is controversial due to the high risk of complications. These complications are partly caused by the...master thesis 2022

Schuurbiers, Stefan (author)Of all reported cases, muscular pain in the arms is the second main cause of work-related musculoskeletal disorders (WMSDs) in European workers. The most popular prevention method for shoulder-related WMSDs are passive shoulder exoskeletons, as of their light weight and ease of use. Yet, due to their static force-angle characteristic, passive...master thesis 2022

van Vliet, Rens (author)Ethiopia is a flourishing country with a rapidly growing economy and population. This is one of the reasons why the capital Addis Ababa is increasingly urbanizing. Due to the free market only providing housing for high incomes, many households live in poor conditions. In addition, these private developments are often built as gated communities...master thesis 2022

Weulen Kranenberg, Dirk (author)The Dutch housing market has a shortage and especially a shortage in its middle-segment between, low-income, social housing, and higher-income, homeownership. Because of this, municipalities have become more active in creating middle-segment housing, but most Dutch municipalities have few land positions which has urged them to create middle...master thesis 2022

Chamarczuk, Michał (author), Draganov, D.S. (author), Quiros, Diego (author), Malinowski, Michał (author)Most of the ambient-noise studies are performed with sensor arrays located at the surface. Passive recordings containing seismic arrivals from subsurface sources could be seen as having a geometry resembling reverse vertical seismic profiling (RVSP). In such scenarios, the intersource seismic-interferometry technique can be used to redatum...journal article 2022

Pecanins Martínez, Victor (author)Several techniques have been proposed to reduce the swing at the input stage of a CTDSM. One of these is using a simple passive RC input stage. In prior works, this increased in-band quantization noise. In this paper, we use positive feedback to realize complex-conjugate poles with a passive input stage, obtaining the same noise-shaping as an...master thesis 2022

Bosscher, Leon (author)The use of passive viscoelastic damping and active piezoelectric damping in a hybrid side-by-side configuration is explored in this paper. The goal is to combine the strengths of both individual methods to achieve better damping performance when targeting a single eigenmode or multiple resonances. It is found that a hybrid configuration where a...master thesis 2022
