    This presentation provides aerosol measurement over Southern Africa, using LIDAR, satellite and sun-photometer. Aerosol formation and processes are also given.
  • Elkaseh, A; Buttner, U; Srinivasu, VV; Perold, WJ (South African Conference on Semi and Superconductor Technology (SACSST) 2009, 2009-04)
    AFM nanolithography was used as a novel cutting technique to define micro-size YBCO superconducting constrictions. Researchers studied the substrate effects on MgO and STO substrates and showed that the observed Shapiro ...
  • Shatalov, MY; Fedotov, I; Wallis, JR; Nicolaides, KE (SACAM 2006, 2006-01)
    A novel unidimensional model of 1-3 piezocomposite ultrasonic transducers is presented. A new electromechanical model is the generalization of the Smith-Auld unidimentional model, which is formulated in terms of a variational ...
  • Ntshabele, K; Isong, B; Dladlu, N; Abu-Mahfouz, Adnan MI (IEEE, 2018-10)
    One of the challenges faced by Wireless sensor networks (WSNs) is the issue of uncontrollable interference as the spectrum becomes congested due to the current proliferation of wireless devices. Cognitive radio (CR) emerged ...
  • Mdukaza, S; Isong, B; Dladlu, N; Abu-Mahfouz, Adnan MI (IEEE, 2018-10)
    Internet of Things (IoT) has attracted widespread applicability not only limited to smart cities and communities but also in water, waste management and so on. It strength lies in the high impacts it created in the daily ...
  • Manuel, M; Isong, B; Esiefarienrhe, M; Abu-Mahfouz, Adnan MI (IEEE, 2018-10)
    Wireless Sensor Networks (WSNs) are network paradigm that are constrained by several challenges such as management of the network, energy consumption, data processing, quality of services (QoS) provisioning, and security. ...
  • Mathebula, M; Isong, B; Gasela, N; Abu-Mahfouz, Adnan MI (2019-06)
    In recent years, wireless sensor networks (WSNs) and software defined networks (SDN) have witnessed overwhelming research interests in both industry and the academia. Most of these researches have been devoted to address ...
  • Smith, S; Naidoo, T; Nxumalo, Z; Land, K; Davies, E; Fourie, L; Marais, P; Roux, P (SPIE Digital Library, 2014-03)
    There is an inherent trade-off between cost and operational integrity of microfluidic components, especially when intended for use in point-of-care devices. We present an analysis system developed to characterise microfluidic ...
  • Teleka, R; Green, J; Brink, S; Sheer, J (2011-11)
    The use of automation in deep level hard rock mines has over the years been overshadowed by mechanized mining. However, more and more readily, the industry is starting to recognize the validity of considering automation ...
  • Teleka, SR; Green, JJ; Brink, S (2011-07)
    In South African hard-rock mines, best practice dictates that the hanging-walls be inspected after blasting. This process is known as ‘making safe’ and although intended to save lives, it is laborious and subjective. ...
  • Stewart, R; Donovan, SJ; Haarhoff, J; Vogt, DR (2008-08)
    AziSA is an architecture for measurement and control networks that can be used to collect, store and facilitate the analysis of data from challenging underground environments. AziSA defines four node classes, two (Classes ...
  • Vogt, D; Brink, AVZ; Stewart, R; Donovan, SJ; Haarhoff, J (3rd International Platinum conference: platinum in Transformation, 2008-10)
    South African underground hard rock mines are typically managed using measurements made daily, weekly or even monthly of key parameters face advance, readiness to blast, blast success, temperature or dust levels. Health, ...
  • Claessens, R; De Waal, A; De Villiers, Pieter; Penders, A; Pavlin, G; Tuyls, K (SCITEPRESS, 2016-04)
    The range of applications that require processing of temporally and spatially distributed sensory data is expanding. Common challenges in domains with these characteristics are sound reasoning about uncertain phenomena and ...
  • Kruger, Carel P; Hancke, GP (IEEE, 2014-07)
    The use of commercial off-the-shelf components for implementing Internet of Things devices has become a common practice amongst researchers and solution providers. IOT solutions, based on the Raspberry Pi, BeagleBone and ...
  • Page, Philip R (2018-11)
    The additional benefit of a recent highly optimal technique which keeps the pressure low and constant at a remote location, above the conventional technique, is discussed. The former technique is called remote real-time ...
