van Duijvenbode, J.R. (author)To extract raw materials responsibly and sustainably, the minerals industry has to continuously optimise the mine-to-metal process and requires an entirely different valuation model. Currently, most operational decisions (e.g., ore-waste boundaries, short-term scheduling, blending policies, dispatch decisions) are evaluated using a revenue-based...doctoral thesis 2023

Marinissen, Annemar (author)Patient motion during an MR scan is still a problem in the medical field. It results in artefacts and reduces image quality which can lead to wrong patient outcomes. A patient moves due to the long scanning times, discomfort, and restlessness. Motion correction techniques are developed to prevent or compensate for the movements. Prospective...master thesis 2023

de Boer, Lotte (author)Icebergs drifting through the Southern Ocean release fresh water and nutrients. This has local impacts on surrounding ecosystems and sea ice formation. On a global scale, salinity patterns and ocean circulation are affected. In addition, <br/> tudying icebergs as a proxy for ice shelves in a warming climate can help predict future climate...master thesis 2023

Bisschop, Femke (author)Mangrove forests are important (sub)tropical intertidal ecosystems providing coastal protection and other ecosystem services like carbon storage and biodiversity. In view of the loss of these forests many rehabilitation projects have started, but unfortunately these efforts often fail. A main cause for coastal erosion is a disrupted (fine)...master thesis 2023

Remeijsen, Pascal (author)Virtual cognitions are simulated inner thoughts, which are presented as a voice over. Previous research has shown the ability of virtual cognitions to increase the self-efficacy and knowledge of the users. When presenting such VR systems to users, having the VR system adapt to the user can improve their efficacy. For instance, by using eye-gaze...master thesis 2023

(author)Extracting the cerebral anterior vessel tree of patients with an intracranial large vessel occlusion (LVO) is relevant to investigate potential biomarkers that can contribute to treatment decision making. The purpose of our work is to develop a method that can achieve this from routinely acquired computed tomography angiography (CTA) and...journal article 2023

Zhang, P. (author), Li, S. (author), Li, Z. (author)Short pitch corrugation is a quasi-periodic rail defect that induces a high level of noise and accelerates track degradation. This paper proposes a methodology to mitigate short pitch corrugation by rail constraint design, including four steps. In Step 1, corrugation is numerically reproduced by employing a three-dimensional (3D) finite...journal article 2023

Shi, Rui (author), Wüthrich, D. (author), Chanson, Hubert (author)Transient motion, turbulence and bubble dynamics make any velocity quantification extremely difficult in unsteady gas–liquid flows. In the present study, novel Eulerian and Lagrangian techniques of velocimetry were developed, using both intrusive and non-intrusive measurements. The selected unsteady gas–liquid flow was a breaking bore,...journal article 2023

Buist, K. A. (author), Nijssen, T.M.J. (author)Magnetic Particle Tracking (MPT) is a relatively new non-invasive measurement technique which is often used to study dense granular flow. Its basic principle relies on tracking the movement of a single magnetic tracer by means of measuring the magnetic field strength at a suitable distance from the tracer. By assumption of a magnetic dipole...journal article 2023

Zhang, P. (author), Li, Z. (author)This paper presents an experimental study on the development mechanism of short pitch corrugation using an innovative downscale V-Track test rig. Rail corrugation is reproduced in the V-Track with two wavelengths of 6.4 mm and 8.9 mm. Based on the measured wheel-rail contact forces, track dynamic behaviors, and observations, the consistent...journal article 2023

Cunillera, A. (author), Bešinović, Nikola (author), Lentink, Ramon M. (author), van Oort, N. (author), Goverde, R.M.P. (author)The dynamics of a moving train are usually described by means of a motion model based on Newton&#x2019;s second law. This model uses as input track geometry data and train characteristics like mass, the parameters that model the running resistance, the maximum tractive effort and power, and the brake rates to be applied. It can reproduce...journal article 2023

Bosma, Detmer (author), Krasnov, O.A. (author), Yarovoy, Alexander (author)A dedicated signal and data processing chain is proposed for a fully polarimetric Doppler surveillance S-band radar to extract the polarimetric signatures of moving targets. To extract the target’s polarimetric features, detection, clustering, and tracking steps are realized for a multi-target environment in the range-Doppler domain. A dedicated...journal article 2023

Lv, Maolong (author), De Schutter, B.H.K. (author), Cao, Jinde (author), Baldi, S. (author)Practical tracking results have been reported in the literature for high-order odd-rational-power nonlinear dynamics (a chain of integrators whose power is the ratio of odd integers). Asymptotic tracking remains an open problem for such dynamics. This note gives a positive answer to this problem in the framework of prescribed performance...journal article 2023

Callejon Cantero, M. (author), Pastor-Rodriguez, A. (author), Siemes, C. (author)The uncertainty on Thermospheric Mass Density (TMD), as derived from atmospheric models, can reach extremely high values. This effect is noteworthy in Low Earth Orbit (LEO), where atmospheric drag is the main perturbing force, as well as the most uncertain. LEO harbours almost 18,000 space objects at the end of 2021, around 60% of the total...conference paper 2023
