NASA plans to launch the Moderate Resolution Imaging Spectroradiometer (MODIS) on the polar orbiting Earth Observation System (EOS) for morning and evening global observations in 1998 and afternoon and night observations in 2000. These 4 MODIS daily fire observations will advance global fire monitoring with special 1 km resolution fire channels at 4 μm and 11 μm, with high saturation at 500K an...

Wildland fires are a function of properties of the fuels that sustain them. These fuels are themselves a function of vegetation, and share the complexity and dynamics of natural systems. Worldwide, the requirement for solutions to the threat of fire to human values has resulted in the development of systems for predicting fire behaviour. To date, regional differences in vegetation and independe...

Abstract Background and objectives: Fire as a frequent phenomenon in rangelands and because of its complicated and different effects on natural ecosystems, has great importance. Awareness of such fire effects on vegetation cover in point of rangeland management after fire is important and helps better Understanding and sustainable management of rangelands. Changing in plant structure and compo...

In this research, fire and radiant heat protection and thermal comfort properties of cotton/nylon-Kermel blended woven fabrics, were utilized to predict the thermal comfort and protection limit of this fabric structure based on Woo and Barker developed model. The results showed that the porosity, the air permeability and the thermal resistance increased with Kermel fiber blend ratio. Conversely...

Visual simulation of fire is used as special effects in movies, applications of fire simulation for the training in disaster prevention. In this paper, we propose techniques for simulating fire spread taking into account the various properties of materials, and for an effective visualization of combustion phenomenon. In our simulation method, the flame dynamics is obtained by combining the Navi...

While ASTM E119-07a is commonly employed to establish a fire rating for a fire resistive material (FRM)/steel assembly, the test method provides little quantitative information on either the thermophysical or adhesion properties of the FRM, beyond indicating that they are sufficient to achieve the measured rating. As part of the Building and Fire Research Laboratory (BFRL) Structural Performanc...

Real-time fire detection, alerting and suppression system detects the presence of fire in indoor scenarios by recording the video inside the room via surveillance camera installed. This system introduces an image processing technique through video surveillance to detect the fire using different experts by combining three classifiers based on color, shape and motion of the fire. This detection s...

and Applied Analysis 3 where f1, g1 T ∈H, f2, g2 T ∈H. From the standpoint of biology, we are only interested in the dynamics of model 1.5 in the region: R2 { u, v | u > 0, v > 0}. 1.8 2. Stability Analysis Firstly, we consider the location stability 14, 15 and the number of the equilibria of model 1.5 in R2 . We can also study autowave solutions 16 of the model. The interior equilibrium point ...
