Investigating the hot gas in active brightest cluster galaxies
(PoS, 2016)We investigate a crucial phase in the cooling–feedback cycle in the star forming Brightest Clus- ter Galaxies (BCGs) by looking at the optical emission line properties of the reheated gas that ultimately causes the cycle ... -
INVESTIGATING WATER DISCLOSURE PRACTISES IN THE PLATINUM MINING INDUSTRY
(2021)Increased population growth and urbanisation have led to signifi cant stress on natural resources, in particular water resources. Various mining-related operations, especially in the platinum ... -
An investigation into measurements and determinants of energy poverty: evidence from cross-section data in Malawi
(The Global Business and Technology Association, 2013)Using economics approaches of measuring energy poverty, the findings of the study suggest that over 90 percent of the households sampled were energy poor. The Logit model of energy poverty reveal that household expenditure ... -
An investigation into the accuracy of the kriging method for multiple Wi-Fi access point RSSI estimation
(SATNAC, 2014)Kriging was originally developed for geographical interpolation purposes, but has proven to be a powerful tool in many other applications as well. In this study we evaluate the accuracy of kriging for Wi-Fi signal ... -
An investigation into the bioavailability of a peroral cannabinoid-Pheroid® formulation
(Elsevier, 2019)Cannabidiol (CBD), a phytocannabinoid isolated from the Cannabis sativa plant, has been investigated for its medicinal properties including anti-psychotic, anti- emetic, anti-inflammatory, anxiolytic and anti- convulsant ... -
An investigation into the economics of fuel management in the freight logistics industry
(IEEE, 2014)The transport and logistics industry has to confront many challenges to achieve the objective of efficient distributed operations, such as vehicle and cargo traceability and security. Research has identified effective ... -
An investigation into the use of the kriging for Wi-Fi RSSI estimation in complex indoor environments
(IEEE, 2015)Kriging was originally developed for geographical interpolation purposes, but has proven to be a powerful tool in many other applications as well. In this study we evaluate kriging for Wi-Fi signal strength estimation in ... -
An investigation into the variation in porosity of a direct metal laser sintered artifact manufactured with the EOSINT M250 machine system using direct metal 20 powder
(RAPDASA, 2014)Direct Metal Laser Sintering (DMLS) is a rapid prototyping technique that allows for direct and rapid manufacturing of complex components. DMLS is however an intricate process and the quality of the final product is ... -
Investigation of 1D system CFD and 3D CFD numerical methodology applied to an experimental facility
(SAAM, 2018)The fourth generation gas-cooled nuclear reactor designs provide a promising prospect for energy and process heat generation. The designs` cycles have high thermal efficiencies, require relatively little fuel and are safe ... -
Investigation of effective chemical flocculation conditions for the treatment of reverse osmosis reject water from coal power plant: a case study
(Desalination Publications, 2020)Power generation processes generate wastewater that is rich in scale-forming agents and which, therefore, requires suitable pre-treatment prior to further treatment with an RO system. In this study, Rheofloc5023 was used ... -
An investigation of industry 4.0 skills requirements
(Univ Stellenbosch, 2019)The Industry 4.0 wave is built on technological advancement that is bringing about significant change. The impact of Industry 4.0 is being felt across all industries, including the education sector. During the 2019 State ... -
Isotope solar modulation with the PAMELA experiment 2019
(Sissa Medialab, 2019)The satellite-borne PAMELA experiment was launched on the 15th June 2006 from the Baikonur cosmodrome. Since then and until January 2016 PAMELA made high-precision measurements of the charged component of cosmic-rays ... -
Issues in software development practices : A South African software practitioners’ viewpoint
(2009)Software development is a process tasked with the development of artefacts that are used to implement organizational information systems. Depending on the social, economical and environmental setting, different ... -
