Augmented supraspinal fatigue following constant-load cycling in the heat
(Wiley, 2015)The development of central fatigue is prominent follow- ing exercise-induced hyperthermia, but the contribution of supraspinal fatigue is not well understood. Seven endurance-trained cyclists (mean ± SD peak O 2 uptake, 62.0 ... -
Automatic alignment of audiobooks in Afrikaans
(Pattern recognition association of South Africa (PRASA), 2012)This paper reports on the automatic alignment of audiobooks in Afrikaans. An existing Afrikaans pronunciation dictionary and corpus of Afrikaans speech data are used to generate baseline acoustic models. The baseline system ... -
Automatic speech recognition for under-resourced languages: A survey
(Elsevier, 2014)Speech processing for under-resourced languages is an active field of research, which has experienced significant progress during the past decade. We propose, in this paper, a survey that focuses on automatic speech ... -

Automatic vs manual assessment of programming tasks
(ACM, 2017)Lecturers are struggling to keep up with their daily responsibilities because of an ever-increasing workload. Manual programming assessment processes are time-consuming, but a possible solution is to use the assistance of ... -
Automation of generalized additive neural networks for predictive data mining
(Taylor & Francis, 2011)For a new technology to make the step from experimental technology to mainstream technology, tools need to be created to facilitate the use of the developed technology in the envisaged application area. Generalized additive ... -
Automation of membrane based solvent extraction unit for Zr and Hf separation
(Elsevier, 2017)In recent years, research into metal ion solvent extraction using hollow fibre membranes has grown. Current studies generally use an analogue controlled experimental setup. Although the analogue system is sufficient for ... -
The awakening of BL Lacertae: observations by Fermi, Swift and the GASP-WEBT
(Oxford University Press, 2013)Since the launch of the Fermi satellite, BL Lacertae has been moderately active at γ-rays and optical frequencies until 2011 May, when the source started a series of strong flares. The exceptional optical sampling achieved ... -
Bacillus pumilus strain YSPMK11 as plant growth promoter and bicontrol agent against Sclerotinia sclerotiorum
(Springer, 2017)A study was executed in a direction to attenuate Sclerotinia stalk rot (SSR) disease through biocontrol agent and also to enhance crop productivity. Culture filtrate of bacterial strain YSPMK11 inhibited growth of Sclerotinia ... -
Bacterial community composition of an urban river in the North West Province, South Africa, in relation to physico-chemical water quality
(Springer, 2016)The aim of this study was to determine the impacts of anthropogenic disturbances on bacterial community composition in an urban river (Mooi River). Physico-chemical analysis, bacterial enumeration and 454-pyrosequencing ... -
Bacterial diversity and mycotoxin reduction during maize fermentation (steeping) for ogi production
(Frontiers Research Foundation, 2015)Bacterial diversity and community structure of two maize varieties (white and yellow) during fermentation/steeping for ogi production, and the influence of spontaneous fermentation on mycotoxin reduction in the gruel were ... -
Bacterial species and mycotoxin contamination associated with locust bean, melon and their fermented products in south-western Nigeria
(Elsevier, 2017)The microbiological safety of spontaneously fermented foods is not always guaranteed due to the unde fi ned fermenting microbial consortium and processing materials. In this study, two commonly consumed traditional condiments ... -
Balance of RNA sequence requirement and NS3/NS3a expression of segment 10 of orbiviruses
(Microbiology Society, 2016)Orbiviruses are insect-transmitted, non-enveloped viruses with a ten-segmented dsRNA genome of which the bluetongue virus (BTV) is the prototype. Viral non-structural protein NS3/NS3a is encoded by genome segment 10 ... -
