  1. Energy and cost optimal scheduling of belt conveyor systems
    Mathaba, Tebello Ntsiki Don, 2017-07-13T13:28:53Z, University of Pretoria
    This work deals with the energy management of belt conveyor systems (BCS) under various demandside management (DSM) programmes. The primary objective of this work is to model the energy consumption and energy related cost of operating troughed belt conveyor systems under different electricity pricin ...
  2. Carbon black : enhancing phase change materials for direct solar application
    Mey, Hennie, 2017-07-13T13:28:54Z, University of Pretoria
    A solar simulator was used to test whether a carbon black additive could increase the solar absorption of a low temperature organic PCM (consisting of a eutectic mixture of palmitic acid and stearic acid). Various PCM and carbon black composites (0.01 % to 6 %) were tested, with the 0.06 % carbon bl ...
  3. Optical thermal and economic optimisation of a linear Fresnel collector
    Moghimi Ardekani, Mohammad, 2017-07-13T13:28:54Z, University of Pretoria
    Solar energy is one of a very few low-carbon energy technologies with the enormous potential to grow to a large scale. Currently, solar power is generated via the photovoltaic (PV) and concentrating solar power (CSP) technologies. The ability of CSPs to scale up renewable energy at the utility level ...
  4. Wind resource assessment and GIS-based site selection methodology for efficient wind power deployment
    Mohammed, Abdul Baseer, 2017-07-13T13:28:54Z, University of Pretoria
    An enormous and urgent energy demand is predicted due to the growing global population, increase in power intensive industries, higher living standards, electrification of remote areas, and globalisation (transportation). Moreover, the global consciousness about the harmful effects of traditional me ...
  5. An insider-outsider"s exploration of planning knowledges roles uses and construction in a post-1994 metropolitan setting : eThekwini Municipality
    Moonsammy, Subhatri Tholsie, 2017-07-13T13:28:55Z, University of Pretoria
    The 21st century calls for new approaches to urban planning theory and practice, in the context of failed but unchanging approaches to planning (UN-Habitat, 2009). What is increasingly clear is that there is an urgent need for the "worlding" of planning epistemology, theory and practice to emerge fr ...
  6. Information monitoring and current awareness services supporting the information behaviour of pregnant women
    Akanbi, Olubukola Mercy, 2017-07-13T13:28:55Z, University of Pretoria
    The future of any society lies with the unborn and young children of that generation: pregnant women are an important part of any society because the outcome of any pregnancy directly affects the hope and future of any society. Provision of reliable pregnancy-related information to pregnant women is ...
  7. Strategy for South African public libraries to bridge the digital divide
    Mphidi, Hamilton Hamilton, 2017-07-13T13:28:55Z, University of Pretoria
    This thesis reports on a study that investigated the role of public libraries in addressing the digital divide in South Africa. The study started in 2006. This study addressed the main research question: "How should a theoretical model look for South African public libraries to contribute to bridgin ...
  8. Thermal management and optimisation of heat transfer from discrete heat sources
    Mujanayi Katumba, Jean-Marc, 2017-07-13T13:28:55Z, University of Pretoria
    These days, the cooling of new generation electronic servers is a challenge due to the immense heat generated by them. In order to avoid overheating caused by the important rise in temperature appropriate cooling procedures must be used in order to meet the thermal requirement. The current study aim ...
  9. The development of a thermoplastic road marking material standard
    Naidoo, Soma, 2017-07-13T13:28:56Z, University of Pretoria
    Public roads without road markings, especially roads carrying high traffic volumes, would lead to chaos and accidents resulting in injuries and loss of life. The road authorities need to ensure that all signage is well maintained and conforms to the Southern African Development Community Road Traffi ...

    Ndala-ka Dlamini, Nathaniel, 2017-07-13T13:28:56Z, University of Pretoria
    The aim of this study was to establish whether or not conflict existed in residential sectional title schemes and if so the causes thereof. Residential sectional title properties, unlike conventional residential freehold properties, imposed co-ownership, co-management and expense sharing amongst own ...
