Giordano, Fabrizio (author)In this study, plume experiments were conducted to mimic the thermodynamic conditions on Saturn's moon, Enceladus. The icy moon subsurface ocean and cracks in the surface have been simulated by using a liquid water reservoir and a narrow channel, while the low-pressure environment at Enceladus’ surface was achieved with a vacuum chamber. We...master thesis 2023

van Batenburg, Tobias (author)Groynes in the Lower Elbe estuary in Germany are subject to attack from overflowing long-period primary ship-induced waves. Damage can occur on the crest and lee side of the structure due to the high turbulent overflowing flow velocities. An actual design tool for groynes exposed to overflowing primary ship waves is not yet present. Therefore,...master thesis 2023

Aguilera Chaves, Mónica (author)Breakwaters are built in coastal zones to alter sediment transport, or protect threatened habitats and port facilities. The rising sea level is causing more water to overtop these structures. Increasing amounts of overtopping discharge can compromise the security of people, or equipment standing on the crest of breakwaters. The overtopping flow...master thesis 2023

Winters, Koen (author)The exposure of certain carbon steels to sour environments can result in severe hydrogen induced cracking (HIC) damage in the oil and gas industry. Current mitigation techniques in this field have low reliability or are not able to provide long-term protection against such damage. Recent advancements in thermal spray technology have resulted in...master thesis 2023

Alcaraz, Mathilde (author)Fibre metal laminates (FML) were initially conceived as a hybrid material, aiming to create synergy between the impact resistance of metals and excellent fatigue resistance of fibre reinforced polymers. The purpose of this approach was to overcome the limitations of single-material structures. However, despite its considerable promise, the use...master thesis 2023

Ramdin, Keane (author)There has been interesting research on the superconducting diode recently. A possible structure for this is the Superconductor/Ferroelectric/Superconductor (S/FE/S) Josephson junction. Our goal is to simulate a S/FE/S junction with a magnetic field and see if this leads to a superconducting diode effect. First this junction and its properties...bachelor thesis 2023

Gründemann, Axel (author)This paper investigates the effect of intrinsic muscle stiffness on neural control parameters in biological musculoskeletal control of stabilisation or reaching tasks. Current model implementations of intrinsic muscle properties are highly simplified, limiting their accuracy in replicating experimental short-range stiffness (SRS) behaviour,...master thesis 2023

Janssen, M.T.G. (author), Draganov, D.S. (author), Barnhoorn, A. (author), Wolf, K.H.A.A. (author)As part of a seismic monitoring project in a geothermal field, where the feasibility of re-injection and storage of produced CO<sub>2</sub> is being investigated, a P- and S-wave seismic velocity characterisation study was carried out. The effect of axial and radial (up to 42 MPa) stress, pore pressure (up to 17 MPa), pore fluid (100% brine...journal article 2023

Marinescu, M. (author), Olivares, Alberto (author), Staffetti, Ernesto (author), Sun, Junzi (author)This paper addresses the problem of spatiotemporal wind velocity field estimation for air traffic management applications. Using data obtained from aircraft, the eastward and northward components of the wind velocity field inside a specific air space are calculated as functions of time. Both short-term wind velocity field forecasting and wind...journal article 2023

Yousuf (author), Athanasiou, Thanos (author), Weinsaft, Jonathan W. (author), Xu, Xiao Yun (author), Dr Pirola, S.P. (author), Redaelli, Alberto (author)Background and Objective: Numerical simulations of blood flow are a valuable tool to investigate the pathophysiology of ascending thoratic aortic aneurysms (ATAA). To accurately reproduce in vivo hemodynamics, computational fluid dynamics (CFD) models must employ realistic inflow boundary conditions (BCs). However, the limited availability of...journal article 2023

(author)In this study non-invasive low field magnetic resonance imaging (MRI) technology was used to monitor fouling induced changes in fiber-by-fiber hydrodynamics inside a multi-fiber hollow fiber membrane module containing 401 fibers. Using structural and velocity images the fouling evolution of these membrane modules were shown to exhibit...journal article 2023

Yuan, S. (author), Zhu, S. (author), Fioranelli, F. (author), Yarovoy, Alexander (author)The problem of estimating the 3D ego-motion velocity using multi-channel FMCW radar sensors has been studied. For the first time, the problem of ego-motion estimation is treated using radar raw signals. A robust algorithm using multi-channel FMCW radar sensors to instantly determine the complete 3D motion state of the ego-vehicle (i.e.,...journal article 2023

Giagnorio, Mattia (author), Tanis, M.B. (author), Hélix-Nielsen, Claus (author), Aschmoneit, Fynn Jerome (author)In forward osmosis, defects on the selective active layer and changes in the porous structure of the support layer can be detrimental factors affecting the membrane performance. This study focuses on the impacts of (i) the possible presence of defects and (ii) the changes in pore structures on the water flux and membrane selectivity via...journal article 2023

Dash, T.K. (author), Gîrdianu, Alexandru (author), Krasnov, O.A. (author), Yarovoy, Alexander (author)At the airports, fast-scanning phased array radars are used to detect point-like targets, e.g., birds and drones. However, these radars do not possess Doppler processing and thus are not used for observation of the weather targets like precipitation events. A series of steps need to be performed, such as beamforming in elevation, target masking...conference paper 2023

Biagini, D. (author), Pascoe, J.A. (author), Alderliesten, R.C. (author)Although several studies have been performed, the compression after impact (CAI) failure of CFRP is still not entirely understood. It is still unclear what sequence of events determines the onset of failure in CAI tests and how the different damage modes are involved in this process. To experimentally investigate this matter, the present work...journal article 2023

(author)Greater landward velocities were recorded after six megathrust earthquakes in subduction zone regions adjacent to the ruptured portion. Previous explanations invoked either increased slip deficit accumulation or plate bending during postseismic relaxation, with different implications for seismic hazard. We investigate whether bending can be...journal article 2023
