    • G2P variant prediction techniques for ASR and STD 

      Davel, Marelie H.; van Heerden, Charl; Barnard, Etienne (Interspeech 2013, 2013)
      Introducing pronunciation variants into a lexicon is a balancing act: incorporating necessary variants can improve automatic speech recognition (ASR) and spoken term detection (STD) performance by capturing some of the ...
    • Galactic cosmic rays in the outer heliosphere: theory and models 

      Florinski, V.; Ferreira, S.E.S.; Pogorelov, N.V. (Springer, 2011)
      We review recent advances in the field of galactic cosmic ray transport in the distant heliosphere. The advent of globalMHD models brought about a better understanding of the three-dimensional structure of the interface ...
    • Galactic propagation of cosmic rays 

      Bisschoff, Driaan (North-West University, 2011)
      The widely used steady-state, rotational symmetric models (2D models) of cosmic ray (CR) propagation, assume smeared-out sources, which do not necessarily result in the same local CR ux as the real local point sources. ...
    • Galactosemia : the South African study 

      Lebea, Phiyani Justice (North-West University, 2006)
      Classic galactosemia and congenital hypothyroidism are both inborn errors of metabolism. The biochemical and molecular detection of both disorders is already defined in scientific literature. Their management is also well ...
    • Galen and his treatise on grief 

      Fitzgerald, John T. (AOSIS, 2016)
      Throughout his career, Fika Janse van Rensburg has rightly insisted on the importance of the socio-historical context in interpreting early Christian literature. Although New Testament scholars have given careful attention ...
    • Game farms as sustainable ecotourism attractions 

      Van der Merwe, Petrus (North-West University, 2004)
      It is clear that tourism, especially ecotourism, in South Africa is growing at a rapid pace. Each year more and more tourists travel to South Africa with their main aim to visit places that are based on the natural ...
    • The Game Object Model and expansive learning: creation, instantiation, expansion, and re-representation 

      Blignaut, Anita Seugnet; Molomo, Bolepo; Amory, Alan (Universiteit van die Vrystaat/ Sabinet, 2011)
      In this paper, the collaborative development, instantiation, expansion and re-representation as research instrument of the Game Object Model (GOM) are explored from a Cultural Historical Activity Theory perspective. The ...
    • Game ranching inter-sectoral linkages: a structural path analysis for South Africa 

      Rossouw, Riaan; Cloete, Philippus C. (Taylor & Francis, 2014)
      Unfamiliarity with the economic structure of the game ranching sector is regarded as one of the reasons why questions are raised with regard to the potential economic impact of continued growth in the sector. This study ...
    • A game theoretic approach to improve energy efficiency of wireless sensor nodes 

      Petzer, Willem Christoffel (2015)
      Wireless sensor networks (WSNs) are becoming increasingly pervasive in a number of applications. Due to the nature of WSNs, one of their biggest constraints is limited node energy. As WSNs grow in popularity, the prevalent ...
    • Games for learning in accountancy education: a systematic literature review 

      Pelser-Carstens, Veruschka; Preston, Margaretha Johanna; Blignaut, A. Seugnet (The Social Sciences Research Society, 2017)
      Background: Games for learning (educational games) are viewed as instructional strategies requiring students to engage in competitive activities with predetermined rules and conditions. Various studies propose beneficial ...
    • Gamifying the industrial engineering profession 

      Darwish, Hasan (IEOM, 2017)
      An age-old problem facing higher education institutes is the verification that the knowledge taught in class was actually learnt and internalized. Many consider that the quality of education is to be measured on this basis. ...
    • Gaming is related to enhanced working memory performance and task-related cortical activity 

      Moisala, M.; Salmela, V.; Lonka, K. (Elsevier, 2017)
      Gaming experience has been suggested to lead to performance enhancements in a wide variety of working memory tasks. Previous studies have, however, mostly focused on adult expert gamers and have not included measurements ...
    • Gamma-gamma absorption in gamma-ray burst environments 

      Dreyer, Lenté; Böttcher, Markus (HEASA, 2016)
      Gamma-ray bursts (GRBs) are the most violent explosions in the universe, seen primarily as bright, short flashes of g-rays. Long GRBs are most likely associated with the violent death of a very massive star. They are ...
    • Gamma-gamma absorption in the broad line region radiation fields of gamma-ray blazars 

      Böttcher, Markus; Els, Paul (IOP Publishing, 2016)
      The expected level of γγ absorption in the Broad Line Region (BLR) radiation field of γ-ray loud Flat Spectrum Radio Quasars (FSRQs) is evaluated as a function of the location of the γ-ray emission region. This is done ...
    • Gamma-gamma absorption in the broad line region radiation fields of gamma-ray blazars. ERRATUM. (2016, ApJ, 821, 102) 

      Böttcher, Markus; Els, Paul (IOP Publishing, 2018)
      In the published article, our code to evaluate the γγ opacity due to the BLR radiation field contained a numerical error, due to which all opacities are a factor of 2π too low. The corrected Figures 2-4 are shown below. ...
    • Gamma-gamma absorption in the γ-ray binary system PSR B1259-63/LS 2883 

      Sushch, Iurii; Van Soelen, Brian (IOP, 2017)
      The observed TeV light curve from the γ-ray binary PSR B1259-63/LS 2883 shows a decrease in the flux at periastron that has not been fully explained by emission mechanisms alone. This observed decrease can, however, be ...
    • Gamma-ray and radio properties of six pulsars detected by the Fermi Large Area Telescope 

      Weltevrede, P.; Venter, C.; Abdo, A.A.; Ackermann, M.; Ajello, M.; Fermi LAT (IOP, 2010)

      Context. The addition of a 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiment’s sensitivityto lower energies. The lowest energy threshold is obtained using monoscopic analysis of data taken with ...
    • Gamma-Ray emission from the shell of supernova remnant W44 revealed by the Fermi LAT 

      Abdo, A.A.; Venter, C.; Ackermann, M.; Ajello, M.; Baldini, L.; Fermi LAT (AAAS, 2010)
      Recent observations of supernova remnants (SNRs) hint that they accelerate cosmic rays to energies close to ~1015 electron volts. However, the nature of the particles that produce the emission remains ambiguous. We report ...
    • Gamma-ray observational properties of TeV-detected blazars 

      Senturk, G.D.; Böttcher, M.; Errando, M.; Mukherjee, R. (IOP Science, 2013)
