DISCRIMINATION OF IN-ORDINAL STATE IN ROOM TEMPERATURE BASED ON STATISTICAL ANALYSIS
Takanashi,Ken-ichi,Daisuke Kozeki,Yoshiyuki Matsubara 한국화재소방학회 1997 한국화재소방학회 학술대회 논문집 Vol.1997 No.-
In this paper, an approach to determine the in-ordinal condition of a room, which is based on multi variable analysis, is proposed. According to this approach, the distance of a state from the ordinal condition is thought to be evaluated by the Mahalanobis' distance. The temperature changes of a room were measured and their statistical characteristics such as distribution type, the mean value and the standard deviation are studied. The applicability of the method for the fire detection is also investigated.
Experimental Study on Fire Hazard of Residential Fires Before and After Sprinkler Activation

Fire experiments were conducted in a real scale room which is assumed to be a residential living room under the various opening conditions and locations of wood crib fire source to study on fire hazard before and after sprinkler activation. Concentrations of oxygen and carbon monoxide, smoke density, and temperature were measured to look into environmental conditions in a room of fire origin. The response time of residential sprinklers was also examined in relation to distance between sprinkler heads and a fire source.
