Author:Botha, G; Zimu, V; Barnard, EDate:Nov 2006The authors investigate the performance of text-based language identification systems on the 11 official languages of South Africa, when n-gram statistics are used as features for classification. In particular, the authors compare support ...Read more
Author:Giwa, O; Davel, MHDate:Nov 2015Text-based language identification (T-LID) of isolated words has been shown to be useful for various speech processing tasks, including pronunciation modelling and data categorisation. When the words to be categorised are proper names, the ...Read more
Author:Louw, Johannes ADate:Dec 2020Sequence-to-sequence end-to-end models for text-to-speech have shown significant gains in naturalness of the produced synthetic speech. These models have an encoder-decoder architecture, without an explicit duration model, but rather a learned ...Read more
Author:De Wet, Febe; Marais, L; Klop, DDate:Sep 2015The purpose of this study was to measure the efficacy of an eBook to improve the vocabulary and word recognition skills in an Afrikaans speaking group of lower socio-economic status of 6- to 7-year old children with poor vocabulary. The main ...Read more
Author:Marais, LDate:Oct 2015Mobile technology and mobile development platforms provide a rich ecosystem within which language and speech related technologies can be developed. Specifically, text-to-speech (TTS) technology provides the opportunity for personalised and ...Read more
Author:Li, Yan; Sreekala, MS; Jacob, MDate:Apr 2009Textile reinforced composites based on natural fibers have been studied by many research groups in recent years due to their good mechanical performances, easy to handle, excellent integrity and reduced manufacturing cost. In this chapter, ...Read more
Author:Oboirien, BO; Engelbrecht, AD; North, Brian C; Du Cann, VM; Falcon, RDate:Nov 2012In this study, the textural properties of chars generated from a vitrinite, high ash coal in a fluidised bed gasifier under air-blown, oxygen-blown and oxygen-enriched conditions were determined by detailed petrographic analysis. The char ...Read more
Author:Pieterse, AmyDate:Oct 2014It is well known that the city regions attract migrants from across the country because of their roles as economic engines and job baskets in South Africa. To address urbanisation implications it is imperative to better understand some of the ...Read more
Author:Folorunso, O; Hamam, Y; Sadiku, R; Ray, Suprakas S; Joseph Adekoya, GJDate:Mar 2020Borophene, a 2-dimensional material with efficacious properties (electrical, thermal and mechanical), is a very promising material that is expected to contribute, significantly, in the revolutionization of electrochemical energy storage, for ...Read more
Author:Nabarro, FRNDate:Mar 1997The Peierls stress is the stress required to move a dislocation through a perfect crystal lattice. Theoretical estimates show an exponential dependence on the ratio of the spacing between gliding planes and the unit slip distance. Nabarro ...Read more
Author:Mvelase, PS; Dlodlo, N; Mathaba, SU; Krause, C; Kabanda, SKDate:Oct 2009This paper reports on a study to determine the information requirements of communities in deep rural areas on government services and how this information can be made available to them. The study then proposes an e-government theoretical ...Read more
Author:Umuhoza, D; Agbinya, JI; Vahed, AnwarDate:2010Sensory data also known as Geospatial data is collected in-situ or remotely by different types of sensors from different geographic locations, by different agencies and over a period of time. A vast amount of data is processed via web services. ...Read more
Author:Yang, Y; Mkhonto, D; Cui, Q; Sahai, NDate:May 2011Bone sialoprotein (BSP) is an acidic, non-collagenous protein specific to bone proposed previously to promote hydroxyapatite (HAP) nucleation and modulate HAP nanocrystal growth. Specifically, two phosphorylated acidic amino acid sequences ...Read more
Author:Kiarii, EM; Govender, Krishna; Govender, PPDate:Nov 2019Clean and green renewable energy is of paramount importance in the world today. Ab initio calculations using density functional theory demonstrate that superlattice structures can result into lowering lattice thermal conductivity and have ...Read more
Author:Gledhill, Irvy MA; Roohani, H; Forsberg, K; Eliasson, P; Skews, BW; Nordström, JDate:Feb 2016Most computational fluid dynamics simulations are, at present, performed in a body-fixed frame, for aeronautical purposes. With the advent of sharp manoeuvre, which may lead to transient effects originating in the acceleration of the centre ...Read morecb
Author:Meissner, Richard; Jacobs-Mata, Inga MDate:Apr 2014Various multi-dimensional governance models have been suggested by scholars and policy makers alike as suitable conceptual lenses through which to view the complexity of water governance, particularly in international river basins. While these ...Read more
Author:Shatalov, M; Fedetov, I; Tenkam, HMDDate:Mar 2008Modern theories of one-dimensional bar vibrations account for lateral effects, which are substantial in the case of relatively thick bars. For example, in the Rayleigh-Love and Rayleigh-Bishop models the lateral displacements are supposed to ...Read more
Author:Shatalov, M; Fedotov, I; Tenkam, HM; Fedotova, TDate:Sep 2010The conventional theory of the piezoelectric rod is based on an assumption that its lateral vibrations are negligible. In this case the rod, vibration could be described in terms of one-dimensional wave equation and a set of mechanical and ...Read more
Author:Greben, JMDate:28 Feb 2006In this paper the author discusses a quantitative theory of trend analysis. Often trends are based on qualitative considerations and subjective assumptions. In the current approach the author makes use of extensive data bases to optimise the ...Read more
