It is a widely recognised fact that the presence of Partial Discharge activity in machines
with an operating voltage exceeding 6,6 kV, enables periodic on-line monitoring of the
condition of these machines. Analysis of ...
Hydrological modelling, simulating surface runoff in a catchment, was a relatively new approach in
South Africa in the mid seventies. The advent of hydrological modelling on a practical level in
South Africa lagged that ...
In certain market situations the llJ9rkeLv_al_ue of dehydrated lu_cern can be increased
dramatically by separati~g the different levels of protein by applying a pneumatic
separation process.

The spincasting process is currently used mainly for casting of low melting point
materials for products such as costume jewellery and fashion items where dimensional
accuracy is not very important.
The shrinkage of the ...
Computer Aided Design (CAD), Rapid Prototyping (RP) and Computer Aided Tomography (CAT)
technologies were researched. The project entails a unique combination of the abovementioned
technologies, which had to be mastered ...
Due to the popularity of 3-dimensional CAD designs, the methods of manufacturing from
these designs are increasing all the time. Rapid prototyping designers and manufacturers
are now able to grow prototypes from the ...
For this research a problem was identified for the small scale pasteurizing of milk in rural areas of
the Free State. The sun was utilized as an energy source for the pasteurizing process. Several
experiments were carried ...
Most commercially available signal generators make use of a phase-locked loop
in combination with analogue frequency synthesis to generate the desired
frequency range. Advances in the development of components being used ...
This dissertation covers the development and implementation of a predictive
maintenance monitoring programme for the Water Supply Directorate of the
Department of Water Affairs, Namibia. The maintenance policy in the ...
The success of the Reconstruction and Development Programme (RDP) with
reference to the electrification of rural areas will be enhanced if cheaper technologies
1 techniques are applied than the three-phase and single-phase ...
When Thomas Edison invented his carbon filament lamp in 1879, gas shares fell
overnight. A committee of inquiry was set up to examine the future possibilities of the
new method of lighting, and had reached the conclusion ...
The Stereo lithography process is a well-known process in South Africa and around the
world. Quotations for designers and inventors are issued daily for the growing of a
prototype of his/her invention or design.
Not all ...
Growing markets leads to an increase in production. In these modern industries,
weight measurement is of high priority. Weight measurement instrumentation is
used for quality control, as well as for effective process ...
Knowing the reproductive status of an animal (sheep in the case of this project) is
of utmost importance to the modern farmer. Decisions concerning the
management of the flock are influenced by knowledge of the percentage ...
The aim of this study was to examine the possibility of more suitable and
economic alternatives to existing conventional sewerage reticulation
systems where such systems might be required.
Existing solids-free systems ...
Programmable logic offers a favourable
vari~ty of logic applications and is
importance in digital designs.

The vacuum casting process plays an important role in Rapid Prototyping. It
provides the designer/manufacturer with the ability to reproduce plastic components
from various types of prototypes.
Casting under vacuum ...
A mass of free moving trout can be determined by using a digital
camera, a computer and special digital processing software (Troutedge).
The aim of this research is to calculate the mass of a trout with the
application ...
There is a need to identify differences between three-dimentional objects
that seem identical to the naked eye. The ability to compare threedimentional
objects will enable one to determine wear that occured on
mechanical ...
Performing an elevated temperature post-cure procedure on glass reinforced plastic vessels
and components that are subjected to aggressive chemical environments enhances the
mechanical and chemical resistant properties ...
