Towards lecture transcription in resource-scarce environments
(Pattern recognition association of South Africa (PRASA), 2012)
We present progress towards automated Lecture Transcription (LT) in resource scarce environments. Our development has focused on the transcription of lectures in Afrikaans from two faculties at North-West University. A ...
Context-dependent modelling of English vowels in Sepedi code-switched speech
(Pattern recognition association of South Africa (PRASA), 2012)
When modelling code-switched speech (utterances that contain a mixture of languages), the embedded language often contains phones not found in the matrix language. These are typically dealt with by either extending the ...
The characterization of the severity of rotor delevitation events: a parametric study
(s.n, 2012)
Active magnetic bearing (AMB) failure and the ensuing rotor behavior is a very important
aspect of AMB safety. A model for this rotor behavior was developed and was used to
characterize the severity of rotor delevitation ...
Experimental results of an asynchronous machine with thermoelectric cooling modules
(2012)
It is estimated that globally around 40% of the electricity supplied to the industrial sector is consumed by electric motorised systems and for South Africa around 60% of the electricity supplied is consumed by asynchronous ...
Validierung eines Gleitfanglagermodells durch Abwurfversuche
(LCM GmbH, 2012)
Der Betrieb magnetgelagerter Maschinen er-fordert grundsätzlich den Einsatz von Fangla-gern. Diese nehmen den Rotor bei Maschinen-stillstand, bei abgeschalteter Magnetlagerung oder bei Magnetlagerversagen auf. Es wird ...
Multilingual pronunciations of proper names in a Southern African corpus
(Pattern recognition association of South Africa (PRASA), 2012)
We present our process for the development and analysis of a multilingual names corpus, called Multipron-split. It is derived from Multipron, a corpus collected in previous work [1], where names and speakers were drawn ...
Glow-in-the-dark globular clusters: modelling their multiwavelength lanterns
(South African Institute of Physics, 2012)
Globular clusters (GCs) are astronomical tapestries embroidered with an
abundance of exotic stellar-type objects, including ancient metal-poor stars, planetary nebulae,
white dwarfs (WDs), low-mass X-ray binaries (LMXRBs), ...
Waste butter and margarine as feedstock for biodiesel production
(ETA-Florence Renewable Energies, 2012)
The resulting bio-waste from butter and margarine factories should be disposed of in an environmentally friendly manner. Currently the bio-waste is either flushed into the municipal sewerage system or moved to landfill ...
Linking export opportunities of products and services: the case of South Africa
(2012)
Trade in services has been playing an increasingly important role in the economic growth and development of many countries. In addition it has been found that services trade is more crisis-resilient than goods trade, leading ...
