Satellite early identification through LED observations: First in-orbit results from WildTrackCube-SIMBA
(Science Direct, 2022-04)Autonomous illumination payloads on-board small satellites, i.e. LED (LightEmitting Diode) boards on CubeSats, can be tracked by ground-based telescopes for optical identification, orbit determination and attitude determination. ... -
Short Term Load Forecasting Using Artificial Neural Networks
(Proceedings of 2013 Mechanical Engineering Conference on Sustainable Research and Innovation, 2013)Load forecasting refers to the prediction of future load conditions based on present or historical data. This is important especially for transmission planning and economic dispatch. In this paper, an Artificial Neural ... -
Signal monitoring and performance stability evaluation tool in a high speed optical communication network
(2016-10)The diverse communication systems in South Africa have changed drastically over the last few years and are envisioned to continue to improve as evidenced by the deployment of high speed optical fibre networks, in both ... -
Simulation model for solar energy harnessing by the solar tunnel dryer
(2010)Models were developed to predict global solar radiation and the energy harnessed by a solar tunnel dryer, and simulated in Visual Basic 6. In addition, the simulated data were compared with actual data. Using a 10% absolute ... -
Societal Implications of IT in Religion for Developing Countries
(2017)Information Technology has penetrated nearly all aspects of our daily lives such that relationships associated with individuals and organizations are digitally enabled and mediated. Advances in IT have led to changes in ... -
Solving The Active Distribution Network Reconfiguration (ADNR) Problem Taking Into Consideration A Stochastic Wind Scenario and Load Uncertainty By Using HBFDE Method
(International Journal of Emerging Technology and Advanced Engineering, 2017)-Past literature has attempted to solve the problem of network reconfiguration with Distributed Generators (DGs) without taking into consideration the intermittent renewable at a close proximity. Distribution ... -
SWAT model parameter calibration and uncertainty analysis using the HydroPSO R package in Nzoia Basin, Kenya
(Journal of Sustainable Research in Engineering, 2014)The parameter uncertainty in hydrological modelling has been accorded much attention in the recent past.Parameter uncertainty is a major source of overall model unreliability. In this study, the HydroPSO R package was used ... -
THIN LAYER DRYING KINETICS OF AMARANTH (Amaranthus cruentus) GRAINS IN A NATURAL CONVECTION SOLAR TENT DRYER
(2010-03)An experimental solar tent dryer under natural convection was used to study thin layer drying kinetics of amaranth (Amaranthus cruentus) grains. Drying of grains in the dryer was carried out on a drying rack having two ... -
TRANSIENT PRESSURE WAVES IN HILLSLOPES
(2013-05)Previous studies found that during a rainfall event, pre-event water, which exists in the catchment before the event, may appear in significant amounts in the stream stormflow hydrograph. Pre-event water is predominantly ... -
