There is, currently, a surge of activity surrounding Arabic corpus linguistics. As the number of available Arabic corpora continues to grow, there is an increasing need for robust tools that can process this data, whether for research or teaching. One such tool that is useful for both of these purposes is the concordancer – a simple tool for displaying a(More)
– Abstract Dans ce papier nous présentons une vue d'ensemble critique d'outils disponibles pour l'analyse de corpus arabes, en nous concentrant sur la concordance (Monoconc : Barlow 2003), l'analyse morphologique et le marquage des catégories grammaticales In this paper we present a critical overview of available Arabic corpus analysis tools, focusing on(More)
Plastic-water phantom materials are not exactly water equivalent since they have a different elemental composition and different interaction cross sections for protons than water. Several studies of the water equivalence of plastic-water phantom materials have been reported for photon and electron beams, but none for clinical proton beams. In proton beams,(More)
The conversion of absorbed dose-to-graphite in a graphite phantom to absorbed dose-to-water in a water phantom is performed by water to graphite stopping power ratios. If, however, the charged particle fluence is not equal at equivalent depths in graphite and water, a fluence correction factor, kfl, is required as well. This is particularly relevant to the(More)
Inspired by the Oxford Children's Corpus, we have developed a prototype corpus of Arabic texts written and/or selected for children. Our Arabic Children's Corpus of 2950 documents and nearly 2 million words has been collected manually from the web during a 3month project. It is of high quality, and contains a range of different children's genres based on(More)
PURPOSE The IAEA TRS-398 code of practice can be applied for the measurement of absorbed dose to water under reference conditions with an ionization chamber. For protons, the combined relative standard uncertainty on those measurements is less than 2% while for light-ion beams, it is considerably larger, i.e. 3.2%, mainly due to the higher uncertainty(More)
