An investigation in the use of satellite data to develop a geomagnetic secular variation model over Southern Africa.
(2011)Time variations of the geomagnetic field can be classified into two main categories of internal and external origin with respect to the surface of the Earth. It has been found that the variations that take place on longer ... -
Measurement and validation of waterlines and surface currents using surf-zone video imaging.
(2001)The continuous monitoring of beaches and structures near, or in the surf-zone, has become a vital task from an environmental and economic standpoint. Specifically, the Durban beaches are continually nourished with sand ... -
Measurement of soil in sugar cane using non-destructive techniques.
(2001)The soil being delivered with sugar cane consignments. from the cane fields to the factories, has been a recent cause for concern in the South African sugar industry. The soil impurities increase the wear of processing ... -
Pharos : pluri-director, high-resolution, analyser of radiometric properties of soil cores.
(2001)The core-logger has been designed for the high-resolution radiometric analysis of soil cores using multiple detectors. This device allows for the automation of the measuring process and eliminates the need to dissect the ... -
A study of plasma source ion implantation.
(1993)The work described in this thesis is an analysis of the Plasma Source Ion Implantation (PSII) process. A metal target is placed within a plasma, and pulsed to a high negative potential (10 - 50 kV). The electrons in the ... -
Two-dimensional plasma sheath observations in plasma source ion implantation.
(1996)Plasma Source Ion Implantation (PSII) is the process of implanting high energy ions [10-50 keV] into metallic targets, by pulsing them negatively whilst immersed in a background plasma. PSII achieves surface hardening, ...
