(author), Huisman, Dennis (author), Panja, Debabrata (author), Schaafsma, Alfons A.M. (author), van den Akker, Marjan (author)Railway systems occasionally get into a state of being out-of-control, meaning that barely any train is running, even though the required resources (infrastructure, rolling stock and crew) are available. Because of the large number of affected resources and the absence of detailed, timely and accurate information, currently existing...journal article 2021

Dijkstra, Y.M. (author), Schuttelaars, H.M. (author)The salinity structure in estuaries is classically described in terms of the salinity structure as well mixed, partially mixed, or salt wedge. The existing knowledge about the processes that result in such salinity structures comes from highly idealized models that are restricted to either well-mixed and partially mixed cases or subtidal salt...journal article 2021

Goeman, Katie (author), Dijkstra, W.P. (author), Poelmans, Stephan (author), Vemuri, Pavani (author), van Valkenburg, W.F. (author)In order to embed blended learning environments in a strategic and sustainable manner, a multi-actor, multidimensional approach is necessary. This paper reports the results of a 3-round Delphi study involving 28 experts which focuses on the refinement and validation of a layered maturity model that assesses key aspects of blended practices in...journal article 2021

Horemans, Dante M.L. (author), Dijkstra, Y.M. (author), Schuttelaars, H.M. (author), Sabbe, Koen (author), Vyverman, Wim (author), Meire, Patrick (author), Cox, Tom J.S. (author)Many estuaries exhibit seasonality in the estuary-scale distribution of suspended particulate matter (SPM). This SPM distribution depends on various factors, including freshwater discharge, salinity intrusion, erodibility, and the ability of cohesive SPM to flocculate into larger aggregates. Various authors indicate that biotic factors, such...journal article 2021

Dijkstra, Jasper (author)Very high energy electron (VHEE) radiotherapy is being investigated as a potential replacement of photon therapy. VHEE pencil beams have a small penumbra and strong depth dependence for radiotherapy when compared to photons. This allows a lower dose to healthy tissue. Generating these high electron energy beams could be...master thesis 2020

van Heteren, Mauries (author), Dijkstra, Jonathan (author)In this thesis, the design of a frequency analysis system for conveyor belt weighing systems is designed. The objective of the thesis is to detect a change in resonance frequency, caused by a change of pressure applied to a sensor. The design features a resolution of 10 000 discrete frequency levels in a bandwidth of 0.5 MHz. Noise division of a...bachelor thesis 2020

Dijkstra, Fokke (author)A variety of statistical methods are available to detect sudden changes, or breakpoints, in time series when used as multi-temporal change detection technique. However, these methods are unreliable in the presence of noise. Neural nets might detect breakpoints better. These deep learning models are able to generalize and optimize well, even in...master thesis 2020

(author)Shallow tropical bays in the Caribbean, like Orient Bay and Galion Bay in Saint Martin, are often sheltered by coral reefs. In the relatively calm environment behind the reefs, seagrass meadows grow. Together, these ecosystems provide valuable ecosystem services like coastal protection, biodiversity hotspots, nursery grounds for animals and...journal article 2020

(author)Removal of organic and inorganic sulfur compounds from sour gases is required because of their toxicity and atmospheric pollution. The most common are hydrogen sulfide (H<sub>2</sub>S) and methanethiol (MT). Under oxygen-limiting conditions about 92 mol% of sulfide is oxidized to sulfur by haloalkaliphilic sulfur-oxidizing bacteria (SOB),...journal article 2020

Fiorucci, Giulia (author), Coli, Gabriele M. (author), Padding, J.T. (author), Dijkstra, Marjolein (author)We investigate the effect of hydrodynamic interactions (HIs) on the crystal nucleation of hard-sphere colloids for varying supersaturations. We use molecular dynamics and stochastic rotation dynamics techniques to account for the HIs. For high supersaturation values, we perform brute force simulations and compute the nucleation rate,...journal article 2020

(author)Sediment transport in estuaries and the formation of estuarine turbidity maxima (ETM) highly depend on the ability of suspended particulate matter (SPM) to flocculate into larger aggregates. While most literature focuses on the small-scale impact of biological flocculants on the formation of larger aggregates, the influence of the...journal article 2020

Dijkstra, Kevin (author)E8 is a famous root system in mathematics. Lisi claims in his paper “An Exceptionally Simple Theory of Everything” that there is a connection between the standard model of the elementary particles and this root system. He claims that standard model has the same structure as the root system E8. If this is true, there must be a mapping from the...bachelor thesis 2019

Dijkstra, Sjoerd (author)In this work we set out to determine the impact, if any, of the analysis of news on stock price prediction, that is, are we able to predict stock movements more accurately on a consistent basis than a proposed baseline or random guessing on the basis of news’ text analysis. We considered a methodology to be more accurate if its success rate is...bachelor thesis 2019

Dijkstra, Y.M. (author)Within estuaries one can often observe areas where the concentration of fine suspended sediments is higher than in the surrounding waters, called estuarine turbidity maxima (ETM). ETM play an important role in the natural and socio-economic value of estuaries. The suspended sediments can for example greatly diminish the value of the estuarine...doctoral thesis 2019

(author)The mesoscale variability in the Caribbean Sea is dominated by anticyclonic eddies that are formed in the eastern part of the basin. These anticyclones intensify on their path westward while they pass the coastal upwelling region along the Venezuelan and Colombian coast. In this study, we used a regional model to show that this westward...journal article 2019
