Management model to optimise the use of reverse osmosis brine to backwash ultra–filtration systems at Medupi power station
(2014)
According to the Department of Water Affairs (DWAF, 2004 p.15), South Africa’s water resources are scarce and extremely limited and much of this precious resource is utilised and consumed in our industries. Treatment and ...
Benefits of improved performance monitoring of mine cooling systems
(2014)
Mine cooling system components are an integral part of a mine's ventilation system. A mine's reliance on these capital intensive components are set to increase as mines deepen. Mine cooling systems consume up to a quarter ...
A testbed implementation of energy efficient wireless sensor network routing protocols
(2014)
Wireless Sensor Networks (WSNs) consist of Sensor Nodes (SNs) spatially removed
from one another, that can monitor a variety of environmental conditions. SNs then
collaboratively communicate the collected information to ...
An investigation into engineering knowledge management : a petrochemical organisation as a case study
(2014)
Modern organisations are increasingly seen as knowledge-based business ventures in which proactive knowledge management is important for competitiveness. The interest in knowledge management seems to have surged across ...
Thermal-fluid simulation of air-to-CO2 finned coil evaporator
(2013)
The increasing global pressure to phase out CFC‘s and HFC‘s has resulted in research focusing again on the use of natural refrigerants. CO2 is one alternative that has very good thermal-fluid characteristics. However, a ...
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 ...
System identification and optimal control of a small-scale unmanned helicopter
(2014)
The use of rotary winged unmanned aerial vehicles in military and civilian applications is rapidly
increasing. The primary objective of this study is to develop an automatic flight control system for a
radio controlled ...
Implementing DSM interventions on water reticulation systems of marginal deep level mines
(2014)
Because of a continuous increase in the demand for electricity in South Africa the country’s largest electricity utility (Eskom) has been under strain to provide electricity. An expansion programme to generate more electricity ...
Engineering change management in a large steel manufacturing company
(2014)
Engineering is inherently a process of constant change. The process of managing engineering changes is however, not a new topic and it is well defined and implemented in various other engineering management philosophies. ...
The integration of two stand-alone codes to simulate fluid-structure interaction in breakwaters
(2013)
Harbours play a vital role in the economies of most countries since a significant amount of international trade is conducted through them. Ships rely on harbours for the safe loading and unloading of cargo and the harbour ...
