    Easton, Jayson Lee, 2017-03-22T14:51:49Z, University of the Western Cape
    High spin excited stats in¹⁹²Tl were studied using gamma-ray spectroscopy. The study included taking an active part in performing the experiment, understanding the experimental procedure, electronics and data acquisition in this experiment. The high spin states in ¹⁹²Tl were produced using a ³⁷Cl be ...
  3. Chemical, physical and morphological changes in weathered coal fly ash : a case study of brine impacted wet ash dump
    Eze, Chuks Paul, 2017-03-22T15:08:50Z, University of the Western Cape
    Fly ash is the major waste material produced by power plants in the combustion of coal to generate electricity. The main constituents of fly ash are Si, Al, Fe and Ca with smaller amount of S, Mn, Na, K, and traces of many other elements such as Co, Cd, As, Se, Zn, Mo, Pb, B, Cu and Ni. Fly ash is u ...
  4. Evaluation of virtual private network impact on network performance
    Nawej, Mukatshung Claude, 2017-03-20T06:37:57Z
    The aim of the study is to investigate what impact the use of VPN has on network performance. An empirical investigation using quantitative research methods was carried out. Two sample scenarios were involved in the study: scenario without VPN and scenario with VPN. In both scenarios, three applicat ...
  5. An exploration of supply chain management practices in the West Rand District Municipalities
    Maleka, Thabisho Nehemia, 2017-03-20T06:40:51Z
    Despite reform processes in the employment of Supply Chain Management (SCM) as a strategic tool in the South African public sector, there are predicaments in SCM practices, especially in municipalities. This notwithstanding, research that demystifies the SCM implementation practices in local municip ...
  6. Modeling and real-time implementation of wireless communication on a typical industrial process
    Ndlovu, Wilson Mabalana, 2017-03-20T08:38:24Z
    Communication amongst field devices, control unit and programming unit in industrial automation networks is essential for bulk production, but largely consists of wired networks that can sometimes be bulky and substantially lack mobility as at times there can arise a need for a field device to be ...
