    • 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 ...

    • Calibration of large Rogowski coils 

      Combrink, Stephanus Lucas (Stellenbosch : Stellenbosch University, 2016-03)
      ENGLISH ABSTRACT: The Square Kilometre Array aims to be the world’s largest radio telescope. South Africa will host the mid to high frequency division of the SKA and the core site will be populated with 64 offset Gregorian ...

    • 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 ...
