  • Dunn, Dwain I; Snedden, Glen C; Roos, T; Hildebrandt, T (American Institute of Aeronautics and Astronautics, 2011-09)
    The design of internally-cooled gas turbine blades requires accurate predictions of distributions of blade temperature values and temperature gradients. This requires accurate predictions of heat transfer distributions ...
  • Hamadou Ibrahim, A; Roux, FS; McLaren, M; Forbes, A; Konrad, T (2013-06)
    This is a power point presentation questioning the feasablility of free space quantum communication with the OAM state of light. Presented June 2013
  • Trichili, A; Mhlanga, T; Naidoo, Darryl; Dudely, A; Zghal, M; Forbes, A (SPIE, 2014-08-17)
    We analyze the effect of atmospheric turbulence on the propagation of multiplexed Laguerre Gaussian modes. We present a method to multiplex Laguerre Gaussian modes using digital holograms and decompose the resulting field ...
  • Gerber, G; Diedericks, G; Basson, GR (American Society of Civil Engineers, 2011-03)
    Particle 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 ...
  • Chaibi, A; Mafusire, C; Forbes, A (IOP Publishing, 2013-09)
    The orbital angular momentum of light has been suggested as a means of information transfer over free-space, yet the detected optical vortex is known to be sensitive to perturbation. Such effects have been studied ...
  • Mafusire, C; Forbes, A; Michaelis, MM; Snedden, Glen C (2009-06)
    The graded index (GRIN-like) medium generated by a gas inside a heated pipe when it is rotated about its longitudinal axis has the ability to focus a laser beam. However, recent research has shown that the medium generated ...
