Nowadays, a lot of precision components are manufactured and have to be measured to check dimensions and geometry. Xpress PE started to develop a coordinate measuring machine with a sub-micron measuring uncertainty called TriNano. The difference between the TriNano and other machines is that the TriNano …

To quantify the dosimetric accuracy of the COMPASS correction kernel method, and to determine its ability to detect dose delivery errors caused by MLC leaf mis-positioning.

Positioning is hot. Not only in the realm of consumer goods manufacturers, but also for other companies, institutions, governments and even individual persons. An explosion of good quality products on the market and targeted media and advertising campaigns has led to an increasing interest from organizations …

The COMPASS system (IBADosimetry) is a quality assurance (QA) tool which reconstructs 3D doses inside a phantom or a patient CT. The dose is predicted according to the RT plan with a correction derived from 2D measurements of a matrix detector. This correction method is necessary since a direct reconstruction …

De Veenkoloniën heeft een relatieve zwakke economie. De Agenda voor de Veenkoloniën heeft aangegeven de toervaart als een van de middelen te willen gebruiken om deze economische positie te versterken. Dit onderzoek richt zich op de ontwikkelingskansen van het toerisme langs de hoofdvaarverbinding Zuidlaardermeer …

This article discusses the revival of the interferometric positioning experiment with GPS signals that aims at measuring the three-dimensional vector between two stations. Such an experiment was carried out in the late seventies, the early days of the GPS system, almost simultaneously by two competing …

In this contribution the current status and future development of four Global Navigation Satellite Systems (GNSS) are reviewed. They are the American Global Positioning System (GPS), the Russian Glonass, the European Galileo and the Chinese BeiDou Compass. All four systems offer, or will offer, civil …

Global Navigation Satellite Systems (GNSS) currently dominate the Positioning, Navigation and Timing (PNT) community and there are no signs that this will change in the near future. But for many years the weeknesses of GNSS have been well known and besides research into GNSS a lot of research into back …

This report was commissioned to examine the possible gap between the image and identity of TUI Nederland regarding sustainable tourism and to recommend on how to bring the image closer to the identity. TUI Nederland is market leader in the Dutch travel industry and carries the brands Arke, Holland International, …

This study explores the capability of the COMPASS system (IBA Dosimetry, Germany) to detect leaf positioning errors of a high resolution MLC with 4mm leaf width using a lower resolution (7.62mm detector spacing) 2D matrix of ionisation chambers
