Cumaru Silva Alves, F.A. (author), Castiel Reis de Souza, A. (author), Lyra, Paulo Roberto Maciel (author), de Carvalho, Darlan Karlo Elisiário (author)The level of detail on modern geological models requires higher resolution grids that may render the simulation of multiphase flow in porous media intractable. Moreover, these models may comprise highly heterogeneous media with phenomena taking place in different scales. Scale transferring techniques allow for the solution of such problems in...journal article 2024

Bron Jacobs, Joachim (author)A Tomographic Background-Oriented Schlieren (TBOS) technique is developed to aid in the visualization of compressible flows. An experimental setup was devised around a sub-scale rocket nozzle, in which four cameras were set up in a circular configuration with 30° angular spacing in azimuth. Measurements were taken of the overexpanded supersonic...student report 2023

Xun, H. (author), Fieback, M. (author), Yuan, S. (author), Zhang, Ziwei (author), Taouil, M. (author), Hamdioui, S. (author)Resistive Random Access Memory (RRAM) is a potential technology to replace conventional memories by providing low power consumption and high-density storage. As various manufacturing vendors make significant efforts to push it to high-volume production and commercialization, high-quality and efficient test solutions are of great importance. This...conference paper 2023

Miranda Xicotencatl, Brenda (author), Kleijn, René (author), van Nielen, Sander (author), Donati, Franco (author), Sprecher, Benjamin (author), Tukker, Arnold (author)Life cycle assessment (LCA) databases and software evolve. We analyzed to which extent software and evolving life cycle inventory databases affect the comparison of technology alternatives, using a comparative LCA on permanent magnets as a case study, with two selected software tools: CMLCA and Brightway LCA. We migrated the system models...journal article 2023

Chandran, Godwin Rayan (author)Video Object Detectors (VID) are used in various applications such as surveillance, inspection, etc. Often in these applications there exists a spatial area of interest and a static background. The static backgrounds remain constant throughout the video sequence in the training data establishing an undesirable correlation with the moving object...master thesis 2022

Gurbaxani, Rishabh (author)Phase-locked loops (PLLs) are ubiquitous in many RF applications such as frequency synthesizers in wireline and wireless transceivers. In this project, a charge-sampling PLL has been designed, which employs a charge-domain sub-sampling phase detector. The high gain of the phase detector helps suppress the in-band phase noise, while the lowered...master thesis 2022

van der Boog, C.G. (author), Dijkstra, Henk A. (author), Pietrzak, J.D. (author), Katsman, C.A. (author)Because of its pronounced fresh signature, the properties of the northward-flowing Antarctic Intermediate Water (AAIW) affect the Atlantic Meridional Overturning Circulation. Hence, understanding modifications of AAIW along its path is important. Here, we analyze AAIW changes along its path in the Caribbean Sea and assess whether vertical...journal article 2022

Strauß, Antje (author), Wu, Tongyu (author), McQueen, James M. (author), Scharenborg, O.E. (author), Hintz, Florian (author)Successful spoken-word recognition relies on interplay between lexical and sublexical processing. Previous research demonstrated that listeners readily shift between more lexically-biased and more sublexically-biased modes of processing in response to the situational context in which language comprehension takes place. Recognizing words in...journal article 2022

van der Meide, Marc (author), Harpprecht, Carina (author), Northey, Stephen (author), Yang, Y. (author), Steubing, Bernhard (author)Cobalt is considered a key metal in the energy transition, and demand is expected to increase substantially by 2050. This demand is for an important part because of cobalt use in (electric vehicle) batteries. This study investigated the environmental impacts of the production of cobalt and how these could change in the future. We modeled...journal article 2022

Miedema, Mark (author)This master thesis investigates the aerodynamic response of the Hyperloop breach failure scenario. Using a scaled physical test setup, the air pressure inside a Hyperloop tube is lowered to 10 mbar, emulating Hyperloop conditions. By opening a breach hole inside the tube, air will flow into the tube due to the pressure difference with the...master thesis 2021

Louwerens, Cornee (author)This graduation thesis was executed within the studio New Heritage in which the question was raised whether postmodern architecture can be valued as heritage. Multiple postmodern neighbourhoods suffer from a stigma. Outsiders have a negative image where insiders are much more positive about their neighbourhood. This master thesis focusses on the...master thesis 2021

Harpprecht, Carina (author), van Oers, Lauran (author), Northey, Stephen A. (author), Yang, Y. (author), Steubing, Bernhard (author)The environmental benefits of low-carbon technologies, such as photovoltaic modules, have been under debate because their large-scale deployment will require a drastic increase in metal production. This is of concern because higher metal demand may induce ore grade decline and can thereby further intensify the environmental footprint of metal...journal article 2021

Drozdova, Polina (author), van Hout, Roeland (author), Mattys, Sven (author), Scharenborg, O.E. (author)There is ample evidence that both native and non-native listeners deal with speech variation by quickly tuning into a speaker and adjusting their phonetic categories according to the speaker's ambiguous pronunciation. This process is called lexically-guided perceptual learning. Moreover, the presence of noise in the speech signal has...journal article 2021

Our filter implementation combines information brought by an ensemble of model realizations, and that based on our prior knowledge about the dynamical system of interest. We perform the combination of...journal article 2021

Macarulla Rodriguez, M. (author)Low-field Magnetic Resonance Imaging (LF MRI) is a cheap and safe technique to visualise the internal structure of the human body. Unlike other imaging techniques, Magnetic Resonance Imaging does not use ionising radiation to generate the images. Instead, it uses magnetic fields and radio waves which are nonthreatening to the health. The LF MRI...master thesis 2020
