Liquids like gasoline comprise a mixture of hundreds of hydrocarbon components. Gas chromatography of these complex mixtures produces highly detailed chromatograms that are characteristic of a particular sample. Although many of the volatile components will be lost during the fire, sufficient less-volatile components may have been left in partially burned wood or other materials to enable the d...

Integrate-and-Fire-type models are usually criticized because of their simplicity. On the other hand, the Integrate-and-Fire model is the basis of most of the theoretical studies on spiking neuron models. Here, we develop a sequential procedure to quantitatively evaluate an equivalent Integrate-and-Fire-type model based on intracellular recordings of cortical pyramidal neurons. We find that the...

temporal and spatial variations of fire behavior can be predicted using one of the semi-physical or empirical models developed over recent years. this article investigates the effect of different fuel moisture conditions on fire spread and behavior in national golestan park in july 2011 using farsite, flammap simulation systems, and previous ignition history. landscape data contains the topogra...

fire consider as a factor and basic management in rangeland in order to reform of composition and biological diversity that use in rangeland ecosystems. this project was established to deal with the effect of fire in the research center for rangeland. zagheh locale where is in 35 km of north eastern of khoramabad with 1960 meters above sea level. the average comparison and analysis show that he...

awareness of the effects of fire on various aspects of an ecosystem after the fire,is important for range management. changes in soil physical and chemical propertiescaused by fire can be the cause of changes in the vegetation. in this study, effects of fire onphysical and chemical characteristics of soil were investigated. this research was carriedout in a randomized block design method in the...

An image-based fire detection method using neural networks is proposed in this paper. First, flame color features, based on the HSI color model, are trained by a backpropagation neural network for flame recognition. Then, based on the learned flame color features, regions with fire-like colors are roughly separated from an image. Besides segmenting flame regions, background objects with similar...

(The post-fire effects on the outcrossing rate of a Brazilian savannah shrub, Helicteres sacarolha A.St.-Hil.). The effect of post-fire, plant density and number of flowers per plant on outcrossing rates was examined in a Brazilian savannah shrub, Helicteres sacarolha. Data on number of flowering plants and flowers per plant were collected during the flowering season in January and February of ...
