Author:Gerber, G; Diedericks, G; Basson, GRDate:Mar 2011Particle image velocimetry scalar measurements were carried out on the body of a stably stratified density current with an inlet Reynolds number of 2,300 and bulk Richardson number of 0.1. These measurements allowed the mass and momentum ...Read more
Author:Arendse, CJ; Knoesen, D; Britton, DTDate:Apr 2006The material properties of hydrogenated amorphous silicon (a-Si:H) have been known to change when exposed to elevated temperatures. In this work the authors report on the thermal stability of the structural disorder, hydrogen content and ...Read more
