Understanding how ignitions occur is critical for effectively mitigating home fire losses during wildland fires. The threat of life and property losses during wildland fires is a significant issue for Federal, State, and local agencies that have responsibilities involving homes within and adjacent to wildlands. Agencies have shifted attention to communities adjacent to wildlands through pre-sup...

In the emergency of a fire or in the aftermath of a disaster, the struck area is rather difficult to access and may have become hazardous, hostile or toxic. Establishing whether the ground can be entered safely by human beings is time consuming. A major challenge is to quickly acquire and gather in situ data and forward information about the actual situation throughout the entire system. The Vi...

We assume that m facility units (hospital, bank, post office, fire department, police station, bus station, etc.) are requested to be established for n cities which are on the same line. We have to choose m cities where the facility units will be established such that total distance from all cities to nearest facility units is minimum. Here, it is supposed that the person who is in the city whi...

Soaring expenditures for fire management in the USDA Forest Service have caused substantial concern over fire management costs, especially in light of questions about the role of fire in ecosystems. This report contains analysis of most Forest Service fire management expenditures between fiscal years 1970-98. Expenditure information was obtained from a variety of sources, including electronic f...

Sand pine (I-‘inu.r c/trrr.srr) scrub is adapted to, and regenerated by, periodic stantl-rcplnccment wildfire, which consumch the understory and kills the overstay. The heat of the fire opens the serotinous cones of’ Ocala sand pine (P. c~/nu.srr var. c/tr~c.sc/), releasing quantities of seed that reestablish the overstory, while the understory regenerates by sproutin, (1 or from soil-stored se...

Fire is a valuable tool for maintaining biodiversity in many ecosystems throughout the world, particularly tropical savannas. An understanding of the impact of different fire management regimes is essential if desired outcomes are to be achieved. Numerous studies have shown patchy and inconsistent responses of insects to fire. This may be because detection of responses to fire was contingent up...

In order to explore the basic events and risk occurrence probability of fire explosion accidents in CNG (Compressed Natural Gas) filling station, a corresponding Bayesian network model was established based on fault tree station. The prior modified by introducing fuzzy mathematics process transforming into network, posterior station analyzed calculated GeNIe software. Finally, through case anal...
