Author:Shikwambana, L; Sivakumar, VDate:Sep 2013This study shows the estimates of aerosol optical depth measured over Pretoria, South Africa, using the CSIR-NLC mobile LIDAR. The measurements are also compared with observations from the Level-3 MODIS aerosol optical depth (AOD) data. The ...Read more
Author:Smakhtin, VUDate:Apr 2001The paper describes a simple technique for baseflow separation from continuous monthly streamflow records which are widely available in South Africa. The technique employs a digital filter algorithm, which has been previously used only with ...Read more
Author:Smakhtin, VUDate:Jan 2000The paper describes two techniques by which to establish 1-day (1d) flow duration curves at an ungauged site where only a simulated or calculated monthly flow time series is available. Both methods employ the straightforward relationships ...Read more
Author:García, CL; Jovanovic, Nebojsa; Teich, I; Fink, M; Dzikiti, Sebinasi; Bugan, Richard DHDate:Apr 2020Reliable spatial data of evapotranspiration (ET) in support of water resources management are limited. ET is a major component of the water balance, in many regions, and therefore it is critical that it be accurately quantified. To identify ...Read more
Author:Ramoelo, Abel; Cho, Moses A; Mathieu, Renaud SA; Skidmore, AK; Schlerf, M; Heitkönig, IMADate:Oct 2012Grass quality and quantity information plays a crucial role in understanding the distribution, densities and population dynamics of herbivores (i.e. livestock and wildlife). Leaf nitrogen (N) and biomass (g/ m2) are indicators of grass quality ...Read more
Author:Gama, MJ; Cho, Moses A; Chirwa, P; Masemola, CeciliaDate:Mar 2019Trees provide low-cost organic inputs, with the potential to improve livelihoods for rural communities. Understanding foliar nutrients of tree species is crucial for integration of trees into agroecosystems. The study explored nitrogen (N), ...Read more
Author:Naidoo, Laven; Main, Russell S; Cho, Moses A; Madonsela, Sabelo; Majozi, Nobuhle, PDate:Jul 2021Sentinel-1 and Sentinel-2 have provided consistent hyper-temporal information (5–7 days or earlier) at high spatial resolutions (10m) on biophysical composition, structural and physiological conditions of crops in a variety of environments. ...Read more
Author:Burke, Michael G; Brink, WDate:Nov 2010This paper presents a monocular vision-based technique for extracting orientation information from a human torso for use in a robotic human-follower. Typical approaches to human-following use an estimate of only human position for navigation, ...Read more
Author:Pieterse, N; Focke, WW; Vuorinen, E; Racz, IDate:Aug 2006Volatile corrosion inhibitors (VCIs) are incorporated into packaging paper or film to protect metals against atmospheric corrosion. The vapour pressure determines the equilibrium concentration of a volatile corrosion inhibitor (VCI) in the ...Read more
Author:Oelofse, Suzanna HH; Nahman, AntonDate:Aug 2012Throughout the developed world, food is treated as a disposable commodity. Between one third and half of all food produced for human consumption globally is estimated to be wasted. However, attempts to quantify the actual magnitude of food ...Read more
