Samenvatting Dit proefschrift gaat over de uitdaging voor leerkrachten in het basisonderwijs om leervragen van leerlingen een plaats te geven in hun onderwijs. Leervragen betreffen vragen die leerlingen zelf stellen, voortkomend uit persoonlijke belangstelling of verwondering en gericht op het willen …

Dit onderzoek is tot stand gekomen als onderdeel van het afstudeertraject van Carlijn Gouwentak, dramatherapeut in opleiding aan de Vaktherapie opleiding van de Hogeschool van Arnhem en Nijmegen. Het doel van dit onderzoek is om vanuit de praktijk en via literatuur inzicht te krijgen of en hoe maskertheater …

This research is an explorative study to look for the potential to predict traffic density from driver behavior using signals collected from the Controller Area Network (CAN) bus. The hypothesis is that driver behavior is influenced by traffic density in such a way that an approximation of the traffic …

The natural gas/diesel dual-fuel engine is an interesting technique to reduce greenhouse gas emission. A limitation of this concept is the emission of un-combusted methane. In this study we analyzed the influence of PFI gas-injection timing on cylinder to cylinder gas-distribution, and the resulting …

The adaptation of high capacity vehicles (HCVs) into existing commercial vehicle fleets have been considered a potential solution for reducing emissions, operational costs and infrastructure damages. However, due to increased length and number of articulations, there are challenges associated with HCVs …

In the search for low greenhouse gas propulsion, the dual fuel engine provides a solution to use low carbon fuel at diesel-like high efficiency. Also a lower emission of NOx and particles can be achieved by replacing a substantial part of the diesel fuel by for example natural gas. Limitations can be …
