    Louw, Willem J. (Stellenbosch : Stellenbosch University, 2005-12)
    ENGLISH ABSTRACT: Both coaxial probe and waveguide (WG) measurement systems for electric and magnetic material property extraction were investigated. These measurement techniques were used to determine electrical properties ...

  • Middleware for the SUNSAT field station 

    Cardoza, Andrew Robert (Stellenbosch : Stellenbosch University, 2001-12)
    ENGLISH ABSTRACT: SRMA currently used on the SUNSAT field station is an effective MAC layer protocol but lacks several features. Sufficient support for flexible communication, acknowledgement of individual data packets, ...

  • Minimum congestion routing for a 17 GHz wireless ad hoc network 

    Kotze, Daniel Johannes Van Wyk (Stellenbosch : University of Stellenbosch, 2011-03)
    ENGLISH ABSTRACT: An investigation is made to find a suitable routing protocol for a millimeter wave ad hoc wireless network. It is discovered that a hierarchical routing protocol is ideal for a high node density. Due to ...
