In pre-treatment dose verification, low resolution detector systems are unable to identify shifts of individual leafs of high resolution multi leaf collimator (MLC) systems from detected changes in the dose deposition. The goal of this study was to introduce an alternative approach (the shutter technique) …

Knowledge of spatial and temporal trends in the environmental exposure to radiofrequency electromagnetic fields (RF-EMF) is a key prerequisite for RF-EMF risk assessment studies attempting to establish a link between RF-EMF and potential effects on human health as well as on fauna and flora. In this …

An improved Preventive Maintenance (PM) process has been created for Shell Pernis. The improved process has closed the loop of Maintenance Execution and Reliability Engineering. Added feedback loops and control points secured continuous improvement of PM plans. This made the process an end-to-end process. …

According to the critics of conventional sustainability models, particularly within the business context, it is questionable whether the objective of balancing the social, economic and environmental triad is feasible, and whether human equality and prosperity (as well as population growth) can be achieved …

The ‘pay gap’ is a relatively new term. However, it is a problem that was developed around the beginning of the 20th century, the moment when women were allowed to hold a paid occupation in the Netherlands and Norway. The pay gap, often confused with unequal pay for the same work, is actually a complex …

There's much discussion about being open, with topics such as open source software, open innovation, open research, and open education. Will the whole world be open, and, if so, what was all closed in the past? The authors analyze the similarities and differences between the open movements they've been …

This article describes the development of foreign fighters’ preparatory modes of operation between 2000 and 2013, based on an analysis of 17 closed police investigations and 21 semi-structured interviews with police investigators, public prosecutors, and lawyers. Through the use of grounded theory methods …

Philips strives to make the world healthier and more sustainable through innovation, in both advanced and emerging markets. There are major differences between these worlds, also in healthcare. This is mainly the result of the limited resources in the emerging countries and the lack of availability of …

The article aims to find predictors of study success from a teacher’s perspective that relate to the built environment. The research is based on a national online survey among 1752 teachers at 18 Dutch Universities of Applied Sciences. Multivariate data analyses were used to test the hypothesis that …

A multilayer scheme is here proposed to implement coordinated control of a group of mobile robots. Specifically, a trajectory tracking controller is proposed to coordinately guide a platoon of robots, with an obstacle deviation subsystem based on virtual forces and mechanical impedance implemented in …
