  • Govender, Avashna; De Wet, Febe (IEEE, 2016-12)
    Building synthetic child voices is considered a difficult task due to the challenges associated with data collection. As a result, speaker adaptation in conjunction with Hidden Markov Model (HMM)-based synthesis has become ...
  • Davel, M; Barnard, E (PRASA, 2005-11)
    In this paper the authors describe a new approach to rewrite rule extraction and analysis, using Minimal Representation Graphs. This approach provides a mechanism for obtaining the smallest possible rule set – within a ...
  • Bateman, P; Tucker, KC (2006)
    The community’s “strength in diversity” was evident throughout the discussion diversity in terms of the members, their perspectives, interests, activities, offerings and contributions. The dynamic list of questions is a ...
  • Varzinczak, IJ (AI Access Foundation, 2010-02)
    As historically acknowledged in the Reasoning about Actions and Change community, intuitiveness of a logical domain description cannot be fully automated. Moreover, like any other logical theory, action theories may also ...
  • Lysko, Albert A (IEEE, 2012-11)
    A circular loop antenna is often numerically modeled using a regular polygon. This approach is simple and robust, yet it alters the circumference of the loop and may thus shift the resonance frequency in the numerical ...
  • Lysko, Albert A (IEEE, 2009-06)
    The paper introduces a method to cover several wire segments with a single basis function, describes related practical algorithms, and gives some results. The process involves three steps: identifying chains of wire segments, ...
  • Namoshe, M; Tlale, NS; Kumile, CM (2008-07)
    Open source software simulators play a major role in robotics design and research as platforms for developing, testing and improving architectures, concepts and algorithms for cooperative/multi-robot systems. Simulation ...
  • Dufois, F; Penven, P; Whittle, CP; Veitch, J (Elsevier, 2012)
    Using in situ sea surface temperature (SST) data and MODIS/TERRA SST, the monthly AVHRR Pathfinder (version 5.0 and 5.2) SST product was evaluated within the four main Eastern Boundary Upwelling Systems. A warm bias in the ...
  • Van Aardt, JAN; Wu, J; McGlinchy, J; Wessels, Konrad J; Mathieu, Renaud SA; Kennedy Bowdoin, T; Knapp, DE; Asner, GP (IGARSS 2012, 2012-07)
    The goals of the study were to (i) determine if there is a direct relationship between waveform LiDAR intensity-by-height and discrete return frequency-by-height (do the distributions match?) and (ii) assess the impact of ...
  • Sahraeian, R; Van Compernolle, D; De Wet, Febe (SLTU 2014, 2014-05)
    This paper demonstrates the application of Intrinsic Spectral Analysis (ISA) for low-resource Automatic Speech Recognition (ASR). State-of-the-art speech recognition systems that require large amounts of task specific ...
  • Arcia-Moret, A; Sathiaseelan, A; Zennaro, M; Rondón, F; Pietrosemoli, E; Johnson, David (ACM Digital Library, 2016-08)
    TV White Spaces have recently been proposed as an alternative to alleviate the spectrum crunch, characterised by the need to reallocate frequency bands to accommodate the ever-growing demand for wireless communications. ...
  • Fisher, R; Ledwaba, Lehlogonolo; Hancke, GP; Kruger, Carel P (MDPI, 2015-03)
    The concept of the Internet of Things is rapidly becoming a reality, with many applications being deployed within industrial and consumer sectors. At the ‘thing’ level—devices and inter-device network communication—the ...
  • Molefe, Onkgopotse M; Fogwill, TA (Information Society Technologies (IST), 2009-05)
    Open Source communities (OSCs), sometimes referred to as virtual or online communities play a significant role in terms of the contribution they continue to make in producing user-friendly Open Source Software (OSS) ...
  • Botha, Natasha; Inglis, H (2018-09)
    The modeling and simulation of composite materials requires the incorporation of anisotropic material models, as well as appropriate failure criteria or damage models. This was normally done by developing in-house codes ...
  • Gush, Kim L (IIMC International Information Management Corporation, 2018-05)
    Monitoring and servicing of technologically complex rural installations poses unique challenges. This paper presents some discussion and a selection of open source tools aimed at assisting help-desk personnel in the ...
  • Macleod, D (Apache Software Foundation, 2013-05)
    With the recent release of an OFED which supports SR-IOV on Infiniband HCAs it is now possible to use verbs from inside a VM. This VMM driver supports these Infiniband HCAs, and any other SR-IOV network device, in OpenNebula.
  • Ndwe, J; Barnard, E; Dlodlo, M; Mashao, D; Kuun, C; Sharma, A (Springer, 2008-09)
    The OpenPhone project aims to design an Interactive Voice Response (IVR) health information system that enables people who are caregivers for HIV/AIDS infected children to access relevant information by using a telephone ...
  • Rawoot, Ishreen; Van Heerden, Adelai; Parker, Laaiqah (AOSIS Open Journals, 2017-07)
    A career within the South African Operational Forces is physically, mentally and emotionally challenging. It is a diverse working environment with its own organisational culture and unique challenges. The aim of the study ...
  • Karsten, AE; Singh, A; Ndhundhuma, I (The authors, 2010-01)
    In this study a commercial FD-OCT (Model OCM1300SS) by Thorlabs Inc., USA was used. This system has the following performance specifications: 1300nm centre operating wavelength, a 110nm 3dB spectral bandwidth, transverse ...
  • Nkosi, SS; Kortidis, I; Motaung, DE; Keartland, J; Sideras-Haddad, E; Forbes, A; Mwakikunga, Bonex W; Kiriakidis, G; Ray, Suprakas S (Elsevier, 2013-09)
    Diluted magnetic semiconductor (DMS) Mn:ZnO thin films with “ring-like or doughnut-like” structures were grown using aerosol spray pyrolysis for 20 and 30 min. Electron paramagnetic resonance revealed the ferromagnetic ...
