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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Design and optimisation of a solar thermal powered Aqua-Ammonia diffusion-absorption heat pump cycle under seasonal variance for residential use
(North-West University (South Africa)., 2021)
The diffusion-absorption refrigerator was patented by Von Platen and Munters (1926). The
conventionally low coefficient of performance and the high driving temperature have been the
focus of most research since its ...
Solving large scale office scheduling problems as combinatorial auctioning problems
(North-West University (South Africa)., 2022)
Within specific
exible work models, employees must reserve an office to gain access to
one. However, over-bookings and double-bookings arise with such approaches. This can
result in the inefficient utilisation of the ...
Water minimisation at the power station using process integration
(North-West University, 2019)
The primary objective of this study is to determine the reduction of the raw water intake of an existing power station by applying process integration techniques to optimise the use of water available in the system. The ...
