An energy efficient mass transportation model for Gauteng
(North-West University, 2011)
Public transportation in South Africa is characterized by little or no consideration for energy efficiency and use of cleaner fuels. In the case of transport planning in South African cities, no assessment of the economic ...
An optimisation approach to improve the throughput in wireless mesh networks through network coding
(North-West University, 2011)
In this study, the effect of implementing Network Coding on the aggregated throughput in Wireless Mesh Networks, was examined. Wireless Mesh Networks (WMNs) are multiple hop wireless networks, where routing through any ...
Assessment of the national DSM potential in mine underground services
(North-West University, 2003)
ESKOM is moving towards a price structure for electricity which reflects, as far as
possible, the real cost of generation. It is called real time pricing (RTP). ESKOM
developed this cost structure to coax customers to ...
Design optimisation and experimental evaluation of a grain vibration screen
(2016)
Mechanical screening is an important process which is used in a wide range of industries. This study focused on screens in the agricultural industry used for cleaning and classifying of grain. Mathematical models were ...
Evaluation of sub- and supercritical Rankine cycle optimisation criteria
(North-West University (South Africa) , Potchefstroom Campus, 2017)
The main purpose for this study has been to model an advanced real Rankine cycle for sub and super-critical boilers with all the components as encountered in the industry mathematically and to optimise each cycle.
First ...
Optimisation criteria of a Rankine steam cycle powered by thorium HTR
(2014)
HOLCIM has various cement production plants across India. These plants struggle to
produce the projected amount of cement due to electricity shortages. Although coal is
abundant in India, the production thereof is in ...
Optimising the operation of underground mine refrigeration plants and ventilation fans for minimum electricity cost
(North-West University, 2003)
This study describes the development and use of a mathematical model that will enable mine operators to
minimise the costs of electricity consumed by the ventilation and refrigeration systems used for
environmental control ...
Incremental FTTH deployment planning
(North-West University (South Africa) , Potchefstroom Campus, 2016)
The use of optical fibres is favoured due to its desirable physical properties and especially
for its high bandwidth transmission capability. The challenges faced in the
design of fibre-based networks, specifically FTTH ...
Evaluation of upstream and downstream process parameters on electrostatic precipitator performance
(2013)
New emission legislation regarding air pollution control, as instructed by the Department of Environmental Affairs (DEA) to Eskom Generation Power Stations, implies a particulate emission limit of 100 mg/Nm3 for all existing ...
Development of a lean optimisation plan for a wire manufacturing process
(North-West University (South Africa), 2019)
The growing demand for maximum operational efficiency has driven organisations towards implementing lean manufacturing as a management philosophy. However, a gap still exists between the available information on lean ...
