BACKGROUND AND PURPOSE: Radiotherapy of the head and neck is challenged by the relatively large number of organs-at-risk close to the tumor. Biologically-oriented objective functions (OF) could optimally distribute the dose among the organs-at-risk. We aimed to explore OFs based on multivariable normal …

This report contains the results of the graduation research of Jurre Kuijper and Martin Volgers. The research goal is to find an appropriate model to calculate the heat transfer under different sets of system conditions. The system in this case is a sewer heat system, which consists of a sewage pipe …

This review aims to identify strategies to optimise radiography practice using digital technologies, for full spine studies on paediatrics focusing particularly on methods used to diagnose and measure severity of spinal curvatures. The literature search was performed on different databases (PubMed, Google …

When treating cancer by radiation therapy it is always the goal to irradiate the tumour as much as possible and to spare the healthy tissue around it.

De eisen die gesteld worden aan de dijken worden steeds strenger door vernieuwend onderzoek. Toch ging het in 1993 en 1995 met hoog water bijna mis. Na onderzoek bleek dat de dijken bijna doorbraken door piping. Bij piping stroomt water onder de dijk door en worden zandkorrels meegenomen. Hierdoor wordt …

Het voornaamste doel van het onderzoek is om het risico op piping in een tweelagensysteem te bepalen. Het onderzoek is uitgevoerd naar aanleiding van dijkverbeteringen aan de Maas in Limburg door waterschap Peel en Maasvallei en waterschap Roer en Overmaas. Deze dijkverbeteringen zijn het gevolg van …

Reflection on the role of social media in social movements, conflicts in civil society and military operations. While acknowleging the use of the digital media as a form of cyber warfare by groups such as Al Qaeda and the Taliban to good effect against ISAF in Afghanistan, the authors suggest that in …

De opdracht van Bosal Nederland was om de huidige bandenstelling volgens het 'Tube 50' systeem te herontwerpen zodat deze goedkopere werd en tegelijk meer functies kreeg. Het eindresultaat wordt in dit verslag beschreven

The studies reported on in this thesis addressed the development of sucking patterns in preterm newborns. Preterm infants often have problems learning to suckle at the breast or to drink from a bottle. It is unclear whether this is due to their preterm birth or whether it is the consequence of neurological …
