Intriago Zambrano, J.C. (author), van Dijk, Ruben (author), van Beusekom, Martin (author), Diehl, J.C. (author), Ertsen, M.W. (author)Use of water pumping technologies (WPTs) to drive pressurized systems in smallholder irrigation schemes is one of the key interventions to secure water, hence to increase yields and to potentially alleviate poverty, as well as to foster local and global good security. Whichever the chosen WPT, smallholders face many decision-making variables...abstract 2020

Keuten, M.G.A. (author), Peters, M.C.F.M. (author), van Dijk, J.C. (author), van Loosdrecht, Mark C.M. (author), Rietveld, L.C. (author)Swimming pools are traditionally disinfected with a residual disinfectant such as sodium hypochlorite. Nowadays, swimming water without a residual disinfectant is increasingly popular, as can be seen by the growing number of (natural) swimming ponds (Weilandt 2015), but health risks for bathers do raise concerns for these type of pools, so some...abstract 2017

Boom, Marco (author), Groenenboom, Max (author), van Dijk, Onne (author), Wooning, Joost (author)ProRail uses multiple custom built software applications to control the train infrastructure in the Netherlands. At this moment these applications experience downtime when they are updated. This interrupts processes that are related to controlling the train services. ProRail asked us to redesign an existing application in such a way that updates...bachelor thesis 2017

van Dijk, Werner (author), van der Werff, Karen (author)There is only a very limited number of moments a skeleton athlete can train at a skeleton track. Therefore, it is important to train as efficiently as possible. To do so, an instrumented skeleton sled is designed that provides useful feedback. This instrumented sled is able to monitor the force exerted on the sled by the athlete and link this to...bachelor thesis 2019

van Dijk, Max (author)In this thesis Bayesian Networks are used to predict European football matches between the years 2008 and 2016. The goal of this research is to see how the structures learned by different Bayesian Network learning algorithms influences the predictions. First the data is explored and modified to be used for Bayesian Networks and secondly the...bachelor thesis 2019

Gianfranceschi, Giuseppe (author), van Dijk, Robbin (author)This research investigates the feasibility of a sensor patch for newborns. A sensor patch would be a device that is applied to the skin of the newborn. It can monitor the patient's temperature, heart rate, respiration rate, oxygen saturation and asses its general appearance of the skin so that it can check the newborn for jaundice. It should...bachelor thesis 2020

van Dijk, Robert (author)The appearance of an object or scene is determined by factors like the material, the lights, the geometry, the position of the observer, and the surroundings.<br/>Changes in these factors can be simulated using a projector-camera setup.<br/>Other research focuses on changing the appearance from the perspective of the projector, or on projector...bachelor thesis 2022

van Dijk, Max (author)Mind wandering is a phenomenon that is used to describe moments where a person's attention appears to shift away to something that is not related to the primary task, which can have a negative influence on the task performance. In this research, the aim is to create a viable algorithm that can automatically detect mind wandering based on eye...bachelor thesis 2022

van Dijk, Jeroen (author)Little to no research has been done on the multi-agent path finding with waypoints problem (MAPFW) even though it has many important real world applications. In this paper we extend an existing algorithm for the multi-agent path finding problem (MAPF) called M* \cite{New}. We do so by ordering the waypoints using a Travelling salesman problem...bachelor thesis 2020

van Vliet, J.I.M. (author), van Dijk, J.M.C. (author), de Tombe, L.J. (author), Marang, R.J. (author), van de Brug, W.G. (author)The aim of this project is to improve the scalability of the Opencraft server. The Opencraft server is based on an open-source implementation of the vanilla Minecraft server. This thesis focuses on improving the messaging system of the Opencraft server. The existing implementation of the messaging system is very basic. It went through all online...bachelor thesis 2020

van Dijk, Hugo (author)Logging user interactions allows researchers to study user behavior in web applications. The LogUI framework can be used to log user interactions on virtually any web application. This framework misses two vital features, a screen capture feature and a dashboard for statistical data analysis and visualization for use in web-based experiments...bachelor thesis 2021

(author), Rodriguez Aguilera, D. (author), Menninga, P.J. (author), Noorlandt, R.P. (author)Sedimentary coasts and shallow-sea beds may be dynamic. The large-scaled spatial variation in these dynamics and the smaller-scaled behaviour of individual marine bedforms are largely unknown. Sea-bed dynamics are relevant for the safety of shipping, and therefore for monitoring strategies, and for offshore engineering projects and...conference paper 2012

(author)Pumped irrigation is a way to improve water control for smallholder farming, hence to intensify its production. In this context, the Dutch company aQysta has developed the Barsha pump (BP), the first-ever commercial version of a hydro-powered pump traditionally referred to as spiral pump. BPs, however, have to deal with several constraints that...conference paper 2019

(author)In the field of robotics, a major challenge is achieving high levels of autonomy with small vehicles that have limited mass and power budgets. The main motivation for designing such small vehicles is that, compared to their larger counterparts, they have the potential to be safer, and hence be available and work together in large numbers. One of...conference paper 2019
