Background and Objectives: Earthquake can be the source of many secondary disasters. Fire is one of the most important secondary hazards after the earthquake. In some cases, post-earthquake fires, in urban areas, may cause far more severe damages than the earthquake itself. After the earthquake, the risk of fire is greatly increased due to the existence of sources of fire, such as arteries of g...
In this investigation, detection dogs are trained and used in identifying red imported fire ants, Solenopsis invicta Buren, and their nests. The methodology could assist in reducing the frequency and scope of chemical treatments for red imported fire ant management and thus reduce labor costs and chemical use as well as improve control and quarantine efficiency. Three dogs previously trained fo...
Wildland fire managers deploy suppression resources to bases and dispatch them to fires to maximize the percentage of fires that are successfully contained before unacceptable costs and losses occur. Deployment is made with budget constraints and uncertainty about the daily number, location, and intensity of fires, all of which affect initial-attack success. To address the deployment problem, w...
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...
Forest fire is considered as the most persistent terrestrial disturbance affecting ecosystems, natural resources and threats to human life. Nepal predominantly faces forest fires during dry seasons (November-June) with increasing trend in recent years that need proper management interventions. In line this, our paper aims at assessing risk zones four districts of central representing different ...
A software system aimed at the simulation of fire spread over complex topography is presented. The software implements a semi-empirical model for fire rate of spread, which takes as input local terrain slope, parameters describing fuel properties as well as the wind speed and direction. Fire shape is described with recourse to an ellipsetype model. Two different models are implemented for the s...
This paper describes an intelligent system for the prediction of forest fire risk in Galicia, a region in north-west Spain. The system has been designed to calculate a risk fire index for each of the 360 squares of 10x10 kms into which the area map has been divided digitally. In our research, the problem was approached using a feedforward neural network. The information used to train the networ...
