On the non-monotonic behaviour of fire spread

Web1 de jun. de 2024 · We then investigated the impact of the dynamic behavior of wind on the forest fire spread. The wind flow model determines the wind direction and speed in each cell and how it spreads. Thus, using these results, we improved subsequently the forest fire spread model proposed in Jellouli et al. (2016). Web30 de out. de 2024 · Hereafter, we consider the behaviour of the overlap as a function of β m when h/β m is held constant relative to the optimal value (τ 0/τ2)/β s.The overlap shows non-monotonic behaviour which reaches its extreme at T m = T s in figure 1;this temperature corresponds to the Nishimori temperature [5]. However, it is non-trivial …
