Factors affecting brinelling and its detection in cylindrical roller element bearings
Brinelling exists ID two fonns, namely true brinelling and false brinelling. Bearing damage due to false brinelling is a common problem and is known to occur on powerstations in Eskom.An example of false brinelling has ...
Neural networks approach to process control : the case of processes with long dead times
This study relates to applications of static artificial neural networks (ANNs) to two basic problems of process control: (a) process model identification, and (b) optimal controller tuning. The emphasis is on model ...
The construction, development and evaluation of a portable ferro- precipitator
This dissertation is concerned with the construction of the locally developed Ferro-precipitator which can be utilised outside a laboratory environment. The American developed Ferrograph machine, besides being expensive ...
Preaging techniques as a means of stabilising thermoelectric drift in nickel-chromium/nickel-aluminium thermocouples for use in an aluminium heat treating furnace
This dissertation is primarily concerned with investigating and improving the degree of accuracy and precision that may be achieved from temperat~re measurements made utilising nickel-chromium/nickel-aluminium (Type K) ...
A study to assess the energy savings potential in the ocean going trawler 'Roxana Bank'
Increasing fuel prices have forced marine engineers and diesel engine manufacturers to look at methods of. reducing fuel consumption without a loss in output power. Engineers are always Investigating the following ...
