Der volle Inhalt der QuelleThis thesis deals with the problem of forest fire detection using image processing and machine learning tools. A forest fire is a fire that spreads over a wooded area. It can be of natural origin (due to lightning or a volcanic eruption) or human. Around the world, the impact of forest fires on many aspects of our daily lives is becoming more and more apparent on the entire ecosystem.Many methods have been shown to be effective in detecting forest fires. The originality of the present work lies in the early detection of fires through the detection of forest smoke and the classification of smoky and non-smoky regions using deep learning and image processing tools. A set of pre-processing techniques helped us to have an important database which allowed us afterwards to test the robustness of the model based on deep belief network we proposed and to evaluate the performance by calculating the following metrics (IoU, Accuracy, Recall, F1 score). Finally, the proposed algorithm is tested on several images in order to validate its efficiency. The simulations of our algorithm have been compared with those processed in the state of the art (Deep CNN, SVM...) and have provided very good results. The results of the proposed methods gave an average classification accuracy of about 96.5% for the early detection of smoke

Der volle Inhalt der QuelleDespite the large expenditure that is dedicated to forest fire suppression in Euro-Mediterranean countries, Australia and North-America, firefighters still face large and severe fire events which eventually entrap them. Investigation of Fire Services’ internal reports addresses here the weather and terrain leading to these dangerous fires. In France, strong wind is the main driver of the largest fires and of the fires that entrap firefighters. However, high temperature is also a key contributor as it influences violent fires with high rates of surface spread. In Australia, a lot of firefighters’ entrapments are due to shifts in wind direction, but others are associated to strong winds in rugged terrain. Whatever the regional specificities, more than 100 firefighters’ entrapments across the world were investigated to find the contribution of dynamic fire behaviors in these entrapments. The results return three different types of fires. During topography-influenced fires, in mountainous area, almost all the entrapments happen on slopes steeper than 20°, prone to flame attachment. During wind-driven fires, leeward slopes prone to vorticity-driven lateral fire spread are the most prominent configurations associated with entrapments. Finally, during convective fires, which are the most violent, entrapments can happen far away from any dangerous configuration. Firefighters should adjust their training courses and promote fire behavior analysts (FBAN) capabilities to benefit from the results of this work and improve their safety. FBAN may consider feedbacks from previous fires to suggest the most efficient and secure firefighting strategies and locations

Der volle Inhalt der QuelleWildfires impacting French forests are currently concentrated in the South, especially in the Mediterranean and Aquitaine regions. Climate projections for the 21st century in France question the impact of climate change on wildfire hazard. We focus on two particular issues: the evolution of the fire danger and fire regime in regions already facing frequent wildfires today, and the potential extension of the risk to new regions in the future.Climate change effect was first determined using projections of an empirical fire danger index (FWI) under future climate, computed for five contrasted climatic models under two greenhouse gases emission scenarios. These projections highlight a very strong increase in fire danger levels in the areas already facing wildfires, especially in the Mediterranean, with a very good agreement between climate models. The range of the increase in the North and the West, though existing, is more challenging to quantify, because of climate model uncertainties.This first approach was limited by the ability of FWI to represent fire activity. Therefore, we developed a probabilistic model for fire activity, aiming at projecting fire numbers and burnt areas under future climate. The approach considers that fires result from underlying random processes that determine the occurrence and the fire size based on the FWI and various spatiotemporal factors. The model was fitted following a Bayesian approach using the Promethee database, which records fire observations in the Mediterranean area. Model projections under historical and future conditions demonstrated that FWI projections underestimated projected fire activity increases, mainly due to the non-linearity of the fire-climate relation. Thus, fire danger increases projected in summer in the Mediterranean in 2080 (pessimistic scenario) are considerably lower (25 to 59%) than those for burnt areas (48 to 202%).This approach does not apply to regions where wildfires are currently sparse, and unreliably recorded, especially in Northern France. Yet we extrapolated the model, established over the Mediterranean area, to the rest of Southern France where data were sufficient. Among the difficulties encountered while extrapolating to the national scale, the variation of fuel structure is a critical issue. It was not included in the projections, but its implications are discussed

Der volle Inhalt der QuelleOne of the causes which supports large scale wildfires is the alarm precision lack. Indeed, firemen need tools able to detect fast and specify a sit of a fire. A new generation of tool is appeared : Wireless Sensor Network. In environemental monitoring, these sensors networks, having decentralized architecture and deployed in a zone, must to transmit their information, by a multi-hop communication, towards a base station. For this communication, the routing protocols attempt to carry out reliable data transmission, while testing to save the energy resources. In the problems of forest fires, the networks of sensors are able to help them firemen. However, we identify three axes for which it is necessary to provide answers : these networks, are they able to envisage, detect and follow a fire ? To answer these questions, the existing simulation tools are incomplete or unusable in our context study. In this essay, we introduce a new application, DEVS-WSN, based on a DEVS description. It allows to study performance and the deployment stratégies of the Wireless Sensor Networks. Moreover, we present a new algorithm of routing VOX, which improves the energy saving and increases lifetime of the network in the particular context of destroying phenomenons. We supplement this theoretical study by a test of Wireless Sensor Network on real fire. All these work advances the conditions of use of Wireless Sensor Network in the fire problems

Der volle Inhalt der QuelleThis work is concerned with a probabilistic study of forest-fire models. The models studied here were introduced in the context of self-organized criticality at the end of the eighties. These models are systems of particles, the trees, defined on connected graphs. Their evolution is governed by two families of Poisson processes, one for the growth of trees, the other one for the ignition of trees by lightning. The influence of lightning is characterized by a parameter lambda > 0. These models were widely studied on Z. However, only the existence and uniqueness of more general infinitevolume forest-fire processes have been proven yet. In this thesis, we studied forest-fire models on Zd for d > 2 and on binary trees, in two directions. The first one is concerned with the existence of stationary measures. The second one is concerned with the study of these processes when the parameter lambda tends to zero. In the first part, we will show the existence of at least one stationary measure for forest-fire processes on Zd, d > 2, for all parameters lambda > 0. The forest-fire processes are Markov processes but not Feller processes, so the usual arguments cannot be used here. Moreover, the geometry of Zd does not allow using the same arguments as for Z. Tools developed while studying these processes on Zd will be used here. In the second part, we will study the behavior of the forest-fire processes on binary trees when the parameter lambda tends to zero. We will begin with the study of a model without any fires, in order to understand better how the clusters of trees grow. We will show a convergence in law of the number of sites of a set construct from a ball of radius and the intersecting clusters, after a time tn > 0, for processes rescaled in space and time. Then, we will add fires and define a modified forest-fire model. In this new model, apart from the cluster of the origin, the clusters evolve under a stationary measure which we expect at the limit in lambda, and not under the dynamic of the initial forest-fire model. For this model, we will show a convergence in law of the rescaled size of the cluster of the origin when it burns for the first time

Der volle Inhalt der QuelleIn this thesis report, we present an approximate modeling approach for discrete events systems. The aim of this research is to develop tools to link modeling and simulation formalism, with fuzzy logic. This new method called iDEVS allows to model and to simulate inaccurate systems. Throughout the manuscript, we discuss various concepts such: take into account inaccuracies with fuzzy sets theory; fuzzy simulation with defuzzification methods…In the first chapter, we present the theories associated with fuzzy logic. In the second chapter, we describe the modeling and simulation concepts, including DEVS formalism. In the third chapter, we explain the method iDEVS, and the tools developed for use. Before concluding, we propose an application of the approach iDEVS to study the spread of forest fires
