Monitoring gearbox oil viscosity by means of motor current signal analysis
(Univ of Huddersfield, 2017)
A number of gearbox failures can be attributed to lubricant related problems. One
measure of the condition of gearbox oil is its viscosity. In electrically powered systems,
motor current signal analysis allows online ...
Simulation of washability and liberation information from photographs
(Springer, 2016)
Imagine that a sample of coal could be crushed unlimited times to the same or different top size; a
different washability would be obtained for each crushing experiment. Depending on the size and
distribution of the raw ...
The South African perspective on the lean manufacturing Respect for People principles
(AOSIS, 2019)
Orientation: Many industries have adopted the popular continuous improvement (CI) approach, lean manufacturing, to facilitate CI initiatives. However, several studies have confirmed that the low success rate of lean ...
Evaluation of cottonseed oil as co-feedstock for the hydroprocessing of petroleum middle distillates for diesel fuel production
(ETA, 2016)
Mandatory blending of biodiesel into petroleum diesel came to effect in 2015 in South Africa. The availability of biodiesel to implement this mandate however poses a challenge for local biodiesel producers and petroleum ...
Dc-bus voltage balancing controllers for split dc-link four-wire inverters and their impact on the quality of the injected currents
(IET, 2017)
The increasing share of single-phase distributed generation units in low-voltage grids causes voltage unbalance problems and overvoltages. Therefore, the need for power quality improving control strategies of grid-connected ...
Decongestion of the distribution grid via optimised location of PV-battery systems
(IET, 2017)
In order to achieve the energy targets for 2020, further integration of renewable energy sources is required.
Hence, there was a need to investigate possible solutions to achieve a reliable network without loss of production. ...
Speech recognition for under-resourced languages: Data sharing in hidden Markov model systems
(South African Journal of Science, 2017)
For purposes of automated speech recognition in under-resourced environments, techniques used to
share acoustic data between closely related or similar languages become important. Donor languages
with abundant resources ...
Comparison of physical properties of oxidative sintered pellets produced with UG2 or metallurgicalgrade South African chromite: a case study
(SAIMM, 2015)
The physical properties of oxidative sintered pellets produced from typical
South African UG2 ore are compared with the physical properties of pellets
produced with conventional South African metallurgical-grade chromite
ore ...
Bilateral G2P accuracy: measuring the effect of variants
(Pattern Recognition Association of South Africa and Mechatronics International Conference, 2017)
Incorporating pronunciation variants in a dictionary
is controversial, as this can be either advantageous or
detrimental for a speech recognition system. Grapheme-tophoneme
(G2P) accuracy can help guide this decision, ...
Spoken language identification system adaptation in under-resourced environments
(Pattern recognition association of South Africa (PRASA), 2013)
Speech technologies have matured over the past few decades and have made significant impacts in a variety of fields, from assistive technologies to personal assistants. However, speech system development is a resource ...
