  • A web-based office climate control system using wireless sensors 
    Foster, Timothy W.; Bhatt, Deep Vardhan; Hancke, Gerhard P.; Silva, Bruno (Institute of Electrical and Electronics Engineers, 2016-08)
    Conventional heating, ventilating, and air conditioning (HVAC) systems usually achieve the desired control level by means of simple ON–OFF control, which can often result in high energy wastage. A potential solution to ...
  • When is it appropriate to model transmission of tuberculosis using a dose response model? 
    Strydom, Duayne; Küsel, R.R. (Ralf); Craig, Ian Keith (Elsevier, 2017-12)
    The risk of transmission of tuberculosis (TB) in confined spaces is analyzed using the Gammaitoni and Nucci model and its variant, a dose response model. The dose response model with its additional parameters has the benefit ...
  • When “okay” is not okay : acoustic characteristics of single-word prosody conveying reluctance 
    Van Zyl, Marianne; Hanekom, Johannes Jurgens (Acoustical Society of America, 2013-01)
    The present study explored the acoustic characteristics of prosodic cues that indicate a speaker’s reluctance when giving permission or agreement using a single word (“okay”). Eight speakers (four male, four female) ...
  • Wi-Fi fine time measurement : is it a viable alternative to ultrawideband for ranging in industrial environments? 
    Elikplim, Nkrow Raphael; Silva, Bruno; Hancke, Gerhard P.; Abu-Mahfouz, Adnan; Shu, Lei (Institute of Electrical and Electronics Engineers, 2023-09)
