  • Ajoodha, R; Rosman, Benjamin (AAAI, 2018-02)
    The recent widespread of availability of sensors, as part of the IoT, presents the opportunity to learn the properties of compound distributions in practical applications. Understanding temporal distributions by observations ...
  • Jansen van Vuuren, Johannes C; Leenen, Louise (Academic Conferences and Publishing International Ltd, 2018-03)
    Cyber Defence is a core driver in the attainment of national security for any country. Perceived Cyberpower can be determined by the analysis of the elements of cyberspace as part of national security. In this paper the ...
  • Leenen, Louise; Aschman, MJ; Grobler, MM; Van Heerden, Adelai (Academic Conferences and Publishing International Ltd, 2018-03)
    Cyber as an operational domain is widely recognised by military forces, but the process to operationalise cyber poses a number of challenges. One of the difficulties is that traditional military culture is far removed from ...
  • Botha, Johannes G; Von Solms, S (Academic Conferences and Publishing International, also Curran, 2018-06)
    Multifunctional devices are employed in office networks for functionality and comfort, most often considered only as peripheral devices enabling the printing, copying and scanning of documents. Based on a study performed ...
  • Van Eden, Beatrice; Rosman, Benjamin S (2018-05)
    The past years have seen many deadly natural disasters including hurricanes, earthquakes, flooding and landslides. Search and rescue efforts have saved numerous lives but numerous others were lost. At the same time, robotic ...
  • Roberts, David P (Southern African Institute of Mining and Metallurgy (SAIMM), 2017-07)
    Bore-and-fill mining was implemented at a pilot site in Tau Tona mine’s shaft pillar on 97 level. Observations, scan data and measurements from this site were used to calibrate an inelastic numerical model of bore-and-fill ...
  • Makondo, Ndivhuwo; Rosman, Benjamin S; Hasegawa, O (2018-05)
    Online learning of a robot’s inverse dynamics model for trajectory tracking necessitates an interaction between the robot and its environment to collect training data. This is challenging for physical robots in the real ...
  • De Saxe, Christopher C; Cebon, D (Taylor & Francis, 2018-06)
    High-capacity vehicles have been shown to be highly effective in reducing emissions associated with road freight transport. However, the reduced manoeuvrability of long vehicles often necessitates the use of active trailer ...
  • Van Heerden, Renier; Von Solms, S; Vorster, J (IIMC International Information Management Corporation, 2018-05)
    The integration of technology in the modern society provides many benefits, but with increased connectivity comes increased risk where governments, businesses and individuals are vulnerable to a variety of cyber-attacks. ...
  • Oyesola, M; Mathe, Ntombizodwa R; Mpofu, K; Fatoba, S (Elsevier, 2018-05)
    Ever changing products, technology and competition make manufacturing a challenging task with respect to responding to market opportunities. A key technology exploited for revolutionary change in the phase of manufacturing ...
  • Maúre, GA; Pinto, I; Ndebele-Murisa, MR; Muthige, Mavhungu S; Lennard, C; Nikulin, G; Dosio, A; Meque, AO (IOP Publishing Ltd, 2018-02)
    Results from an 25 regional climate model simulations from the Coordinated Regional Downscaling Experiment (CORDEX) Africa initiative are used to assess the projected changes in temperature and precipitation over southern ...
  • Mathabathe, Maria N; Bolokang, Amogelang S; Govender, Gonasagren; Mostert, RJ; Siyasiya, CW (Pergamon-Elsevier, 2018-08)
    The y-TiAl intermetallic alloy doped with Nb, Cr, and Si metals has been developed. It has emerged that the ternary Ti-48Al-2Nb and quinary Ti-48Al-2Nb-0.7Cr-0.3Si alloys yielded the best mechanical and cyclic oxidation ...
  • Modiba, Rosinah; Chauke, H; Ngoepe, P (2017-09)
    The study on the Ti-based materials and its application has been the interest of many research industries. These alloys are known to have an ordered B2 phase at high temperatures and transform to a stable low B19 martensitic ...
  • Can Görür, O; Sivrikaya, F; Rosman, Benjamin S; Albayrak, S (ACM, 2018-03)
    We propose an architecture as a robot’s decision-making mechanism to anticipate a human’s state of mind, and so plan accordingly during a human-robot collaboration task. At the core of the architecture lies a novel stochastic ...
  • Marom, O; Rosman, Benjamin S (AAAI, 2018-02)
    A key challenge in many reinforcement learning problems is delayed rewards, which can significantly slow down learning. Although reward shaping has previously been introduced to accelerate learning by bootstrapping an agent ...
  • Page, Philip R (Hindawi, 2018-05)
    The sensitivity of a pressurised water distribution system (WDS) to state parameter variations is studied. A novel local regional sensitivity analysis (LRSA) approach is introduced which applies the same change to a ...
  • Mthethwa, Sthembile; Dlamini, Nelisiwe P (2018-03)
    Hardcopy document forgery is still a challenge and occurs frequently nowadays. Many countries have reported a lot of cases, including South Africa where government issues documents are forged. Protecting these documents ...
  • Ntlangu, Mbulelo Brenwen; Baghai-Wadji, A (Association for Computing Machinery (ACM), 2017-12)
    With the advent of Internet of Things (IoT) technology, the need for tools which facilitate the development and management of network based services has become increasingly important. Issues such as network security and ...
  • Letting, LK; Hamam, Y; Abu-Mahfouz, Adnan MI (MDPI, 2017-08)
    Demand estimation in a water distribution network provides crucial data for monitoring and controlling systems. Because of budgetary and physical constraints, there is a need to estimate water demand from a limited number ...
  • Makondo, Ndivhuwo; Hiratsuka, M; Rosman, Benjamin S; Hasegawa, O (Fuji Technology Press, 2018-04)
    The number and variety of robots active in real-world environments are growing, as well as the skills they are expected to acquire, and to this end we present an approach for non-robotics-expert users to be able to easily ...
