  • Ngcobo, S; Litvin, I; Burger, L; Forbes, A (SPIE Proceedings, 2014-02)
    In this paper we outline a simple laser cavity which produces customised on-demand digitally controlled laser modes by replacing the end-mirror of the cavity with an electrically addressed reflective phase-only spatial ...
  • Chipangura, B; Van Biljon, J; Botha, Adèle (IDIA Proceedings 2012, 2012-09)
    Developing countries and South Africa in specific have shown phenomenal growth in the mobile sector. This has resulted in some challenges and opportunities for alleviating digital poverty through distance education. One ...
  • Phahlamohlaka, J; Modise, M; Nengovhela, N (CSIR. Defence Peace Safety and Security, 2010-10)
    Since it was coined in the early eighties following the Maitland commission for worldwide telecommunications development, much has been written about the concept of digital divide. Everything to date in the literature about ...
  • Smith, R; Cambridge, G; Gush, K (2006-02)
    The Digital Doorway is a joint project between the Department of Science and Technology (DST) and the Meraka Institute, with a vision of making a fundamental difference to computer literacy and associated skills in Africa. ...
  • Cambridge, G (CSIR, 2008-11)
    The Digital Doorway is a joint project between the South African Department of Science and Technology (DST) and the Meraka Institute of the CSIR. The project aims at promoting computer literacy and associated skills in ...
  • Stillman, L; Herselman, M; Marais, Mario A; Pitse Boshomane, M; Plantinga, P; Walton, S (2012)
    The application of the Living Lab (LL) approach to social-technical innovation to the Digital Doorway Initiative in the informal settlement of informal settlement Zandspruit near Johannesburg is outlined in the context ...
  • Stillman, L; Herselman, M; Marais, Mario A; Pitse-Boshomane, M; Plantinga, P; Walton, S (2010-11)
    The application of the Living Lab (LL) approach to social-technical innovation to the Digital Doorway Initiative in Zandspruit near Johannesburg is outlined in the context of the initiative’s evolution from an educational ...
  • Sibiya, G; Venter, HS; Fogwill, T (International Information Management Corporation (IIMC), 2012-05)
    The advent of cloud computing provides good opportunities for both good and malicious use. Cloud computing is at its infancy stage and its security is still an open research issue. Malicious users take advantage of the ...
  • Sibiya, G; Fogwill, T; Venter, HS; Ngobeni, S (IEEE Xplore, 2013-09)
    Although cloud computing is maturing, security issues are still prevalent. Most of the security issues that are in the cloud have existed since the advent of the Internet. These issues are escalated in a cloud environment ...
  • Grobler, MM (2010-05)
    With the explosion of digital crime, digital forensics is more often applied. The digital forensic discipline developed rather rapidly, but up to date very little international standardization with regard to processes, ...
  • Sibiya, G; Venter, HS; Fogwill, T (IEEE, 2015-05)
    The advent of cloud computing has brought new challenges to digital forensics. To address these challenges, new approaches in conducting digital forensic are required. In this paper, challenges that are faced by digital ...
  • Herselman, Marlien; Botha, Adele; Toivanen, H; Myllyoja, J; Fogwill, Thomas; Alberts, Ronell (IEEE, 2016-05)
    The purpose of this paper is to provide an overview of how a digital health innovation ecosystem was conceptualised and validated for South Africa. Largely, we focus on defining strategies to build Digital Health Innovation ...
  • Iyawa, GE; Herselman, Marlien; Botha, Adele (Elsevier, 2016-10)
    This paper reviews existing literature on digital health innovation ecosystems. It aims to explore the terms digital health, innovation and digital ecosystems to identify components towards presenting a conceptual framework ...
  • Mhlanga, T; Trichili, A; Dudley, Angela L; Naidoo, Darryl; Zghal, M; Forbes, A (SPIE, 2014-10-02)
    High-capacity data transmission has been implemented using single channel optical systems. This technique is limited and soon it will be unable to ful ll the growing needs for higher bit rate data transmission. Hence multi-mode ...
  • Phelp, D (CSIR, 2008-11)
    This paper describes a low cost video system ‘Harbour Watch’, which can be used to support safe port operations, especially in developing countries. Preset digital images are geo-referenced and then archived for later ...
  • Herselman, PLR; Cilliers, Jacques E (2007-09)
    In modern information and sensor systems, the timely estimation of the carrier frequency of received signals is of critical importance. This paper presents a digital instantaneous frequency measurement (DIFM) technique, ...
  • Herselman, PL; Cilliers, Jacques E (2006-02-27)
    This paper presents the Digital Instantaneous Frequency Measurement (DIFM) technique, which can measure the carrier frequency of a received waveform within a fraction of a microsecond. The resulting frequency range, ...
  • Ngcobo, S; Litvin, I; Burger, L; Forbes, A (Nature Publishing Group, 2013-08)
    Customizing the output beam shape from a laser invariably involves specialized optical elements in the form of apertures, diffractive optics and free-form mirrors. Such optics require considerable design and fabrication ...
  • Forbes, A; Ngcobo, S; Burger, L; Litvin, IA (SPIE, 2014-02)
    In this paper we will outline our recent advances in all-digital control of light. Importantly, we will outline how to create a so-called “digital laser”, where a conventional laser mirror is replaced with a phase-only ...
  • Botha, Adèle; Ford, M (2008-10)
    Technology has changed the world we live in and has come to be both villified and acclaimed, often for the same reasons. Whilst mobile phones in particular, have tremendous potential as knowledge exchange devices in the ...
