  • The calculation of fluid flow through a torque converter turbine at stall 

    Van der Merwe, Joachim Christoffel (Stellenbosch : University of Stellenbosch, 2005-12)
    The two-dimensional flow-field through the stationary blade row of a radial inflow turbine in a torque converter was analysed by means of a potential flow model and a viscous flow model. The purpose was to compare the ...

  • Calculation of the forces on a moored ship due to a passing container ship 

    Swiegers, Pierre Brink (Stellenbosch : Stellenbosch University, 2011-12)
    ENGLISH ABSTRACT: When a sailing ship passes a moored ship the moored ship experiences forces and moments. These forces and moments cause the moored ship to move. The resulting ship motions due to the passing ship can ...

  • The calibration of compound crump and sharp-crested gauging weirs in South Africa 

    Wessels, P. (Pieter) (Stellenbosch : Stellenbosch University, 1996-12)
    ENGLISH ABSTRACT: The present network of now gauging stations in South Africa has grown from isolated observations on an ad extensive is to an extensive network of stations across the country. Standardised gauging ...

  • The calibration of material properties for use in discrete element models 

    Horn, Etienne (Stellenbosch : Stellenbosch University, 2012-03)
    ENGLISH ABSTRACT: One of the main challenges in using the Discrete Element Method (DEM) is to specify the correct input parameter values. In general, the models are sensitive to the input parameter values and accurate ...

  • Calibration of UV-sensitive camera for corona detection 

    Du Toit, Nicolaas Serdyn (Stellenbosch : University of Stellenbosch, 2007-03)
    Electrical energy is continuously transported across the world by high voltage transmission lines. These transmission lines are however subject to losses beside the inherent resistive and dielectric losses. This additional ...

  • Call centre design, operation and optimisation : a structured and scientific based approach 

    Du Preez, Johan Joubert (Stellenbosch : University of Stellenbosch, 2008-03)
    Call centres form an increasingly important part of the modern day business environment and perform an important role in the strategic and operational aspects of organisations. Call centres have emerged and developed to ...

  • A CAN based distributed telemetry and telecommand network for a nanosatellite 

    Khumalo, Simphiwe (Stellenbosch : Stellenbosch University, 2008-03)
    A communications protocol is designed for real time control and data handling for a Nanosatellite application. The communication protocol is based on the Controller Area Network (CAN) technology. The protocol handles ...
