  • Van der Ham, Gert A. (Stellenbosch : Stellenbosch University, 2001-12)
    ENGLISH ABSTRACT: The trends in worldwide fuel consumption and availability were studied, these indicated a bigger growth in gaseous fuel use than that of crude oil over the last decade. The economics (cost of converting ...
  • De Villiers, Eugene (Stellenbosch : Stellenbosch University, 1998-12)
    ENGLISH ABSTRACT: The flow resistances in the inlet sections of counterflow wet-cooling towers are investigated and correlations are derived for inclusion in a one-dimensional tower performance model. The rain zone loss ...
  • Schoevers, Jacobus Engelbertus (Stellenbosch : Stellenbosch University, 2008-03)
    ENGLISH ABSTRACT: Conventional pulse oximetry has limited accuracy in measuring blood oxygen saturation in low saturation and perfusion scenarios. This limits the application of pulse oximetry in patients su ering from ...
  • Sobiyi, Kehinde Kolawole (Stellenbosch : University of Stellenbosch, 2011-03)
    ENGLISH ABSTRACT: The purpose of this study is to investigate the machinability of commercially pure (CP) titanium, manufactured using the press-and-sinter PM process. To this end, CP titanium powder (-200 mesh) was ...
  • Heunis, Johannes Jacobus (Stellenbosch : University of Stellenbosch, 2011-03)
    ENGLISH ABSTRACT: The vibrations and noise “pollution” that rail vehicles produce have become of particular concern in recent years. More pressure is being placed on operators of trains and trams (especially those operating ...
  • Van der Merwe, Schalk Willem (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: The valveless micropump holds great potential for the biomedical community in applications such as drug delivery systems, blood glucose monitoring and many others. It is also a critical component in ...
  • Husselman, M. (Stellenbosch : University of Stellenbosch, 2005-12)
    This study involved the modeling and verification of the finger follower valve train arrangement with the focus on the non-linear behaviour of high speed valve springs. The project was divided into three phases namely; ...
  • Williams, Paul Ngcebo Tudor (Stellenbosch : Stellenbosch University, 2002-12)
    ENGLISH ABSTRACT: In the design or modification of internal combustion (IC) engine components, the South African Automotive industry has always relied on either design by mother companies or quasi-empirical design ...
  • Northcote, Nicholas M.  (Stellenbosch : University of Stellenbosch, 2006-03)
    Shunt and shuffle in a vehicle drivetrain are two driveability related phenomena responsible for driver discomfort. They are experienced as a sharp jerk (shunt) followed by a series of longitudinal oscillations (shuffle) ...
  • Holtz, Marco Wilfried (Stellenbosch : University of Stellenbosch, 2008-03)
    Suspension seats are commonly used for earth moving machinery to isolate vehicle operators from vibrations transmitted to the vehicle body. To provide the required stiffness and damping for these seats, air-springs are ...
  • Verwey, Aldo (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: A reactor cavity cooling system (RCCS) is used in the PBMR to protect the concrete citadel surrounding the reactor from direct nuclear radiation impingement and heat. The speci ed maximum operating ...
  • Crous, Pieter Gobregts (Stellenbosch : Stellenbosch University, 2000-03)
    ENGLISH ABSTRACT: The utilisation ofDraglines to remove overburden in surface mining operations is often the process that determines the output of these operations. The bucket and its rigging have been identified as ...
  • Van Vuuren, Christiaan Michael (Stellenbosch : Stellenbosch University, 2001-04)
    ENGLISH ABSTRACT: This thesis is concerned with unsteady, one-dimensional flow, which closely mimics those found in the manifolds of internal combustion engines. The physical equations describing problems of this nature ...
  • Dreyer, Antonie Christoffel (Stellenbosch : University of Stellenbosch, 2008-03)
    This thesis aims to contribute to the modelling and analysis of MEMS gyroscope technologies. Various gyroscope types are studied, and the phase-based vibratory gyroscope is then selected for further investigation. In ...
