Skoolhoofleierskapstyl deur die lens van die kultuurhistoriese aktiwiteitsteorie (KHAT)
(Suid-Afrikaanse Akademie vir Wetenskap en Kuns, 2017)Followers' perceptions are the best evaluation of leadership styles. How followers observe a leadership style may differ from how the leader sees it. In order to understand the entire reality, one should accept and respect ... -
SMALLHOLDER MAIZE FARMER’S WILLINGNESS TO JOIN INDEX INSURANCE IN VHEMBE DISTRICT: LIMPOPO PROVINCE
(IBC, 2021)Only a negligible proportion of smallholder farmers in South Africa have crop insurance to mitigate production risks. This article analyses the demand for index-based crop insurance by smallholder farmers in ... -
Smart whiteboard for interactive learning
(IEEE, 2018)The need for educators conveying information more interactively has increased as we are moving into a more technological era. A need for increasing the efficiency of lectures has become very important. This project addresses ... -
SmartRoad: a new approach to law enforcement in dense traffic environments
(IEEE, 2015)Road transport law enforcement is facing new challenges against the background of increasingly congested traffic conditions. An ideal law enforcement system must enable authorities to detect, identify and act against illegal ... -
SO2-drought interaction on crop yield, photosynthesis and symbiotic nitrogen fixation in soybean (Glycine max)
(Springer, 2013)South Africa has an energy-intensive economy, resulting in substantial SO2 pollution. Well watered and drought stressed soybean (Glycine max) were exposed to SO2 in open-top chambers to study the physiology of SO2 injury ... -
Soil quality in the basin of mine effluents and the potential of alleviation of metal dispersion
(CUMTP, 2014)The soils along the basin ofmine effluent were investigated for their role in the mitigation of the pollution of river water in the residential areas around Potchefstroom in South Africa.The results showed that the soils ... -
Sol-gel preparations of ZnO/SnO2 composite photocatalysts applied for the degradation of PAH’s under visible light
(EARET, 2018)Wastewater treatment challenges faced by conventional methods have necessitated the need for alternative/complementary methods that are environmentally benign and efficient especially toward recalcitrant organic pollutants. ... -
Solar modulation of cosmic ray positrons in a very quiet heliosphere
(PoS, 2017)Since the beginning of the space exploration era, solar activity was observed at its lowest level during 2006 to 2009. During this period, the PAMELA space experiment observed spectra for galactic cosmic rays, specifically ... -
The solar modulation of protons and anti-protons
(Sissa Medialab, 2019)A comprehensive, three-dimensional drift model is used to study the solar modulation of cosmic-ray protons and particularly of anti-protons. Spectra for protons and anti-protons from 10 MeV to 70 GeV are computed based on ... -
Solar power pumping system for domestic appliances
(IEEE, 2014)With the world encountering huge pollution problems, use of renewable energy is being encouraged in place of fossils fuels for electricity generation. On such renewable energies is solar power. Solar powered systems are ... -
Solar powered DC refrigerator with a monitoring and control system
(IEEE, 2018)Food, medicine and vaccine in developing countries are often difficult to preserve due to epileptic power supply from the utility companies. In other to reduce the over dependence on the utility company and harness the ... -
The South African salt story: where are we and where are we heading?
(Karger, 2017)Background and objectives: The mortality and morbidity burden caused by hypertension are preventable and therefore, efforts need to be taken to address this burden. Excess dietary sodium ... -
Spam email classifcation with generalized additive neural networks using ensemble methods
(SATNAC, 2014)Solutions to minimize the amount of junk mail we receive are not yet optimal and thus research towards an improved spam email classifier is ongoing. Traditional content and listbased filters are less effective than ... -
Spatial and temporal assessment of atmospheric OC and BC concentrations at South African debits sites
(SASAS, 2014)The baseline of uncertainty in aerosol radiative forcing is large and depends on aerosol characteristics (e.g. size and composition), which can vary significantly on a regional scale. Sources (natural, anthropogenic and ... -
Spectral modelling of a H.E.S.S.-detected pulsar wind nebula
(SAIP, 2015)In the last decade ground-based Imaging Atmospheric Cherenkov Telescopes have discovered roughly 30 pulsar wind nebulae at energies above 100 GeV. We present first results from a leptonic emission code that models the ... -
Spectral variability signatures of relativistic shocks in blazars
(Sissa Medialab, 2018)Mildly relativistic, oblique shocks are frequently invoked as possible sites of relativistic particle acceleration and production of strongly variable, polarized multi-wavelength emission from relativistic jet sources ... -
State estimation for a hexapod robot
(IEEE, 2015)This paper introduces a state estimation methodology for a hexapod robot that makes use of proprioceptive sensors and a kinematic model of the robot. The methodology focuses on providing reliable full pose state estimation ... -
Statistical modelling of an ammonium nitrate fluidised bed granulator for inference measurement
(Elsevier, 2019)Fluidised bed granulation is a widely used wet granulation technique. The operation of a fluidised bed granulator (FBG) as well as the quality of the product is strongly influenced by multiple process variables and ...
