  • Zbonak, A; Bush, T (2006-09)
    An investigation was conducted to test the feasibility of near infrared spectroscopy (NIR) as a tool for predicting the microfibril angle (MFA) of solid wood samples of Pinus patula. Thirty 14 year-old trees were selected ...
  • Marais, EL (2006)
    The importance of traceability for every measurement that is made cannot be over-emphasised. For calibration and testing laboratories, traceability is normally imported through calibration of the standards and equipment ...
  • Paige-Green, P (The Geological Society, 2007)
    Performance-related specifications for the selection of gravel materials for use in unsealed roads were developed in South Africa in the late 1980's along with associated deterioration models. The implementation of these ...
  • Vhengani, L; Lubbe, M; Griffith, D; Lysko, M (South African Institute of Physics, 2010-10)
    The success or failure of any earth observation mission depends on the quality of its data. Data quality is assessed by determining the radiometric, spatial, spectral and geometric fidelity of the satellite sensor. The ...
  • Griffith, D; Lysko, M; Bezuidenhout, D (2009-07)
    Internationally, the remote observation of Earth is rapidly maturing alongside the need for higher accuracy in radiance measurements. Accuracy of, and confidence in Earth radiance measurements is vital for applications ...
  • Monem, S; Singh, A; Karsten, AE; Amin, R; Harith, MA (Springer-Verlag Berlin Heidelberg, 2015-12)
    Tissue simulators, the so-called tissue phantoms, have been used to mimic human tissue for spectroscopic applications. Phantoms’ design depends on patterning the optical properties, namely absorption and scattering ...
  • Leigh, L; Helder, D; Behnert, I; Deadman, A; Fox, N; Leloglu, UM; Özen, H; Griffith, D (IEEE IGARSS 2011, 2011-07)
    The Tuz Gölü site does demonstrate some challenges for being used as an absolute calibration site. These include: spatial and temporal variability on the order of +/- 0.02, atmospheric transmittance variability on the order ...
