Abstract

This paper is devoted to the determination of the origin point in forest fires propagation using a control algorithm. The forest fires propagation are mathematically modelled starting from a reaction diffusion model. A volume of fluid (V.O.F.) formulation is also used to determine the fraction of the area which is burnt. After having developed the objective functional and its derivative, results from an optimization process based on the simplex method is presented. It is shown that the ignition point and the final time of the fire propagation are precisely recovered, even for a realistic, non‐horizontal, terrain. Copyright © 2007 John Wiley & Sons, Ltd.

## A BSTRA CT The transmission paths of vibration from the factoryfloor of the board mill to the floating' flloor of the control room were identified using vibration intensity measurements. The method proved to be useful although the bending stiffness of the floor was not known exactly. The usual
