Backup bearing modelling for turbo machines with high axial and radial loads
(s.n, 2014)
The use of active magnetic bearings (AMBs) in turbo
machines is an active research topic and the implementation in
industrial applications is becoming commonplace. This is
especially true when investigating the backup ...
Development of a controller for fuel cell and supercapacitor application
(CATSA (Catalysis Society of South Africa), 2014)
The growing demand for energy in the world causes a lot of pressure to the environment and the resources used to supply the energy.
To ensure a continuous, more reliable and environmentally friendly energy supply system ...
Study on energy losses in industrial sector caused by low actual efficiency of induction motors
(IEEE, 2014)
This paper presents a study on energy losses in the industrial sector caused by low actual efficiency of induction motors (IMs). The main reasons are discussed and an efficiency analysis of a 3-phase induction motor, ...
Improving energy consumption of an induction motor by design of a power factor correction system and estimation of it's saving on a large scale
(IEEE, 2014)
Power factor correction (PFC) is common in commercial and industrial applications. A need to extend its application increased with the dwindling natural resources used for power generation and also exceeding energy demand, ...
Ontwerp van ’n transmissielyn-monteringsoplossing vir ’n onbemande vier-rotor helikopter
(AOSIS, 2014)
A need
exists for a transmission line monitoring system for use by Eskom to inspect transmission
lines. A solution which uses a single board computer, visual and infrared cameras and a
GPS module is described. Real-time ...
A generalized additive neural network application in information security
(Tadbir Operational Research Group, 2014)
Traditionally spam has been considered as an inconvenience requiring workers to sift through and delete large numbers of e-mail messages per day. However, new developments and the Internet have dramatically transformed the ...
Ontwerp van 'n energiebestuurstelsel vir optimale energieverbruik en effektiwiteit van 'n distribusievlakmikrokragnetwerk
(2014)
South African state-owned utility company, Eskom, is under severe pressure to ensure the stability and reliability of the national electricity grid. With a shortfall in capacity of the national electricity grid, the ...
Intelligente beheer van 'n effektiewe hernubare-energie tenk vir melkboerdery
(2014)
To reduce strain on Eskom and decrease the cost for producing dairy products, an energy-efficient bulk storage tank using solar power was designed. The system uses thermoelectric cooling modules as a supporting cooling ...
Design of a transmission line monitoring solution for an unmanned quadcopter
(2014)
Eskom owns thousands of kilometres of transmission lines that need to be inspected in order to plan maintenance. Current methods of inspection are costly and ineffective and could pose safety risks. Systems already developed ...
