  1. Evaluation of stiff testing of rock
    Vogler, Ulrich Walter Otto Ludwig, 2015-05-07T08:45:39Z
    When designing structures in rock, accurate and relevant information on the mechanical properties of the materials encountered is essential. While laboratory testing of rock materials provides some of the required data, it is important that the reliability and limitations of the information gained a ...
  2. Risk assessment of overhead line hardware on the Eskom distribution business
    Mashaba, Sylvester, 2015-05-07T08:51:21Z
    This research report describes a holistic view of the impacts that ESKOM Distribution is currently facing due to poor quality overhead line fittings supplied by local and international manufacturers. Overhead line fittings are components/hardware used to connect power lines to function as a network. ...
  3. Investigation of polyethersulfone (PES) hollow fiber membrane for the treatment of acid mine drainage
    Mthethwa, Velinjani, 2015-05-07T08:55:17Z
    Efforts in treatment of acid mine drainage (AMD) have been fraught with limitations for the mining industry. Membrane filtration technology is a new alternative employed to treat AMD in this work. A commercially available polyethersulfone (PES) hollow fibre nanofiltration membrane was investigated f ...
  4. A study of flotation froth phase behaviour
    Bhondayi, Clayton, 2015-05-07T08:59:49Z
    The performance of the froth phase, usually evaluated as froth recovery determines overall flotation performance. In most flotation operations, recovery across the froth is rate controlling; consequently understanding the froth phase is very critical. Although much research effort to understand the ...
  5. Optimization of biodiesel production from waste cooking oil using a membrane reactor
    Moyo, Langa B, 2015-05-07T09:03:31Z
    In view of the growing concerns over depleting energy resources, alternative renewable fuels such as biodiesel have been identified as a possible means of addressing the short fall in energy supply. The source of feedstock for biodiesel production has been an ongoing debate and waste cooking oil is ...
  6. Performance of Wi-Fi coordination schemes for VolP in the presence of FTP data.
    Selepe, Kgaugelo Zacharia, 2015-05-07T09:45:17Z
    Evolved 3GPP cellular core networks have made co-existence of heterogeneous Wireless Access networks (HetNets) possible. The evolved core network along with the development of multimode end user devices have led to the realisation of converged Access Networks. Wireless Local Area Networks (WLANs) ...
  7. Work flow in reactive processes: systematic approach to process synthesis
    Bahunde, Teta, 2015-05-07T09:53:29Z
    The industrial sector’s large energy use presents itself as a vast potential for energy saving and technology improvements, making it an attractive target for industrial sustainability through increased energy efficiency. Process synthesis is a tool used early in the design stage of a process to ge ...
  8. Insertion/deletion error correction using path pruned convolutional codes and extended prefix codes
    Saeed, Muhammad Waqar, 2015-05-07T09:59:47Z
    Synchronization error correction has been under discussion since the early development of coding theory. In this research report a novel coding system based on the previous done work on path-pruned convolutional codes and extended prefix synchronization codes is presented. This new coding scheme is ...
  9. Heat treatment and corrosion behaviour of 2101 duplex stainless steel cathodically modified with ruthenium
    Olaseinde, Oluwatoyin Adenike, 2015-05-07T10:05:27Z
    The objective of this study was to improve the overall corrosion ressitance of 2101 by cathodic modification with ruthenium. Initially, the corrosion behaviour of 2101, 316, 2205 and 2507 was studied by potentiodynamic tests. Samples of 2101 with different amounts of ruthenium up to 10wt% were manu ...
  10. The role of NGOs in the development of technical skills among the youth in Alexandra, Johannesburg
    Nkere, George Okezie, 2015-05-07T10:10:08Z
    A research report submitted in partial fulfilment of the requirement for the degree of Master of Science in Development Planning in the Faculty of Engineering and the Built Environment, University of the Witwatersrand, Johannesburg ...
