Author:Louw, Johannes A; Moodley, AvashlinDate:Dec 2017In this paper an automatic method to implicitly model intonation for statistical parametric speech synthesis (SPSS) is presented. The approach is ideally suited to single speaker speech databases as used in text-to-speech (TTS), due to the ...Read more
Author:Badenhorst, JAC; Van Niekerk, DR; Barnard, EDate:Nov 2006Improving the pronunciations of non-native language learners is an important task in a multilingual society. We focus on segmental aspects of pronunciation, and investigate the design of automated assistants that can be used to improve (1) ...Read more
Author:Dawood, Zubeida C; Keet, CMDate:Sep 2017Modularity has been proposed as a solution to deal with large ontologies. This requires, various module management tasks, such as swapping an outdated module for a new one or a computationally costly one for a leaner fragment. No mechanism ...Read more
Author:Burke, Ivan D; Van Heerden, Renier PDate:Mar 2016Cyber awareness training has become a growing industry, with more and more organisations starting to focus on training personnel on how to behave in a secure manner when engaging in cyber operations.

Author:Marais, ELDate:2006At the end of 2005 it was decided that a number of measurements performed in the dc Low Frequency (dclf) Laboratory of the CSIR National Metrology Laboratory (CSIR NML) could benefit from automation. The measurements identified were typically ...Read more
Author:Teleka, Ruth; Green, JJ; Brink, SDate:Jul 2011In South African hard-rock mines, best practice dictates that the hanging-walls be inspected after blasting. This process is known as ‘making safe’ and although intended to save lives, it is laborious and subjective. Pressure is placed on the ...Read more
Author:Heyes, AMDate:Jun 1998The failure of vehicle components is an area which is likely to affect all of us at one stage or another. In this paper the distribution of component failures is discussed, as well as the causes thereof. Four case studies are presented to ...Read more
Author:Berman, R; Benade, R; Rosman, Benjamin SDate:Nov 2015In most countries throughout the world, heavy vehicle use on public roads are governed by prescriptive rules, typically by imposing stringent mass and dimension limits in an attempt to control vehicle safety. A recent alternative framework ...Read more
Author:Olwal, TO; Van Wyk, BJ; Djouani, K; Hamam, Y; Siarry, P; Ntlatlapa, Ntsibane SDate:Sep 2008Multi-Radio Multi-Channel (MRMC) systems are key to power control problems in WMNs. Previous studies have emphasized throughput maximization in such systems as the main design challenge and transmission power control treated as a secondary ...Read more

Author:Maina, JW; Ozawa, Y; Matsui, KDate:Jun 2009The importance of accounting for material nonlinearity and anisotropic behaviour in order to improve the resilient models for pavement materials and numerical analysis is presented in this paper. Effects of material inhomogeneity on the ...Read more
Author:Long, Craig S; Loveday, Philip W; Groenwold, AADate:Jan 2009Two new solid-of-revolution axisymmetric finite elements, which account for hoop fibre rotations, are introduced. The first is based on an irreducible formulation, with only displacement and rotation fields assumed independently. The second ...Read more
Author:Dudley, Angela L; Litvin, I; Roux, FS; Forbes, ADate:Jul 2012This presentation analyses the azimuthal decomposition of optical modes. Decomposition of azimuthal modes need two steps, namely generation and decomposition. An azimuthally-varying phase (bounded by a ring-slit) placed in the spatial frequency ...Read more
