• The Use of Light Scattering and Ion Chamber Responses for the Detection of Fires in Diesel Contaminated Atmospheres
  6/1/2002 - Peer reviewed journal articles
  Experiments were conducted to determine the optical scattering properties of diesel particulate matter (DPM) and various combustion aerosols from both flaming and smoldering combustion sources at discrete angles of 151 and 301 in the forward direction...
• In Mine Evaluation of Discriminating Mine Fire Sensors
  6/1/2002 - Conference papers
  An evaluation of multiple mine fire sensor types for nuisance alarm discrimination. The response of multiple fire sensor types to three small coal fires and three small conveyor belt fires in the presence of diesel emissions was evaluated.
