Where there is smoke, there is fire.

An Automatic Detection of the Fire Smoke Through Multispectral Images

One of the consequences of a fire is smoke. Occasionally, monitoring and detection of this smoke can be a solution to prevent occurrence or spreading a fire. On the other hand, due to the destructive effects of the smoke spreading on human health, measures can be taken to improve the level of health services by zoning and monitoring its expansion process. In this paper, an automated method is p...

Simulation of Metro Train Fire in an Underground Station of Tehran Metro Line 7

In this research a fire scenario was simulated in one of the stations of the line 7 of Tehran's subway system. The Line 7 is under construction and the ventilation system is under design. Fire was set for a stopping metro train at the platform of the station. A 160 meter length eight-car metro train with the forth wagon on the fire was studied. The heat release rate is based on a quadratic f...

Fire detection using video sequences in urban out-door environment

Nowadays automated early warning systems are essential in human life. One of these systems is fire detection which plays an important role in surveillance and security systems because the fire can spread quickly and cause great damage to an area. Traditional fire detection methods usually are based on smoke and temperature detectors (sensors). These methods cannot work properly in large space a...

Mitochondrial DNA damage, oxidative stress, and atherosclerosis: where there is smoke there is not always fire.

Simulation of Smoke Emission from Fires in High-Rise Buildings Using the 3D Model Generated from 2-Dimensional Cadastral Data

Having a 3-Dimensional model of high-rise buildings can be used in disaster management such as fire cases to reduce casualties. The fundamental dilemma in 3D building modeling is the unavailability of suitable data sources. However, available cadastral 2D maps could be used as low-cost and attainable resources for 3D building modeling. Smoke will be a great threat to people's health during a f...

The Sense of Being Stared At: Fictional, Physical, Perceptual, or Attentional/Intentional

According to a well-known adage of folk psychology, “where there is smoke, there is fire.” In his two-part contribution to this symposium on “the sense of being stared at,” Rupert Sheldrake examines some of the smoke (fictional allusions, anecdotal observations and reports, and the persisting lore) surrounding this alleged phenomenon and attempts to determine whether such smoke might indeed be ...
