    • Assessment of the national DSM potential in mine underground services 

      Den Boef, Martinus (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 

      Bloem, Johann (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 ...
    • An energy efficient mass transportation model for Gauteng 

      Nassiep, Kadri Middlekoop (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 ...
    • Evaluation of sub- and supercritical Rankine cycle optimisation criteria 

      Pieters, Petrus Johannes (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 ...
    • Evaluation of upstream and downstream process parameters on electrostatic precipitator performance 

      Peens, Gert Petrus (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 ...
    • Improving energy cost performance of steel production mills 

      Van Niekerk, S.G.J. (North-West University, 2018)
      The global steel supply capacity is more than the demand. This has caused an increase in competition and imports to some countries. South Africa is one of the affected countries and the effects have been seen in the closing ...
    • Incremental FTTH deployment planning 

      Laureles, Jonabelle (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 ...
    • Mine ventilation characterisation through simulations 

      Nel, A.J.H. (North-West University, 2018)
      The profitability of the mining industry is contingent on the industry’s ability to improve upon the status quo of operational efficiency. If the archaic operating methods of mines are altered to embrace and incorporate ...
    • An optimisation approach to improve the throughput in wireless mesh networks through network coding 

      Van der Merwe, Corna (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 ...
    • Optimisation criteria of a Rankine steam cycle powered by thorium HTR 

      Van Niekerk, Steven Cronier (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 ...
