A control system for the efficient operation of bulk air coolers on a mine
(2015)Eskom provides 98% of South Africa’s ever increasing electricity demand. The mining sector is a vital contributor to the economy, but also consumes vast amounts of electricity. This sector is responsible for almost 15% of ... -
The cost-effectiveness of comprehensive system control on a mine compressed air network
(2014)Compressed air leakage accounts for up to 42% of electrical energy loss on a typical mine compressed air system. By using underground control valves it is possible to reduce the amount of air leakage. Underground valve ... -
The development of a system to optimise production costs around complex electricity tariffs
(North-West University, 2012)Rising South African electricity prices and reduced sales following the 2008 economic recession have led cement manufacturers to seek ways to reduce production costs. Prior research has shown that reduced electricity costs ... -
Development of an energy management solution for mine compressor systems
(North-West University, 2010)Eskom is under increasing pressure to provide reliable and sustainable electricity. Demand Side Management (DSM), offers a short– to medium–term solution to this problem. During 2009, the mining sector consumed approximately ... -
A systems engineering approach to coronary heart disease
(North-West University (South Africa) , Potchefstroom Campus, 2015)Coronary heart disease (CHD) is the largest cause of death globally. This is worrying considering the substantial investments made in the research and prevention of CHD. It may be possible that the current reductionistic ...
