Full textAdapting cities to extreme heat is a major challenge in urban planning. One of the key strategies involves increasing urban greening by developping cool islands or green corridors. These developments necessitate a reimagining of urban spaces and planning practices. Studying the impact on air temperature and thermal comfort of urban greening at the metropolitan scale is a research challenge in both urban climate modeling and territorial planning. At the intersection of climatology and geography, this thesis utilizes tools and methods from these disciplines to formulate a method for constructing greening scenarios. This research, aimed at developing decision-support tools, uses Dijon Métropole as a case study. The theoretical framework proposed for co-constructing and modeling territorial planning scenarios is that of geospective. The methodological approach is structured into two phases: (1) the validation of a reference simulation and (2) the creation of vegetation scenarios and the associated climate simulation.To simulate the impact of the scenarios at the metropolitan scale, Méso-NH coupled with TEB/SURFEX is ideal as it integrates the modeling of both upper and lower layers of urban vegetation. Constructing a realistic reference simulation requires an accurate description of land use. Upon identifying that urban vegetation is poorly represented in freely accessible databases, the thesis constructs a high-resolution urban vegetation database using very high-resolution satellite imagery. The validation of a reference simulation within the framework of a research-action project involves verifying whether the results are close to the measured air temperatures in the territory. Dijon Métropole is equipped with an air temperature observation network that covers the entire metropolitan area. Validating a reference simulation within the framework of a research-action project involves assessing whether the results closely align with the measured air temperatures in the territory. The data needed to obtain this reference tends to be accessible in most territories, making this method generalizable, provided that observation data is available for the studied period.The co-construction of urban greening scenarios is part of a research-action project carried out in the Dijon area from 2020 to 2024. Geospective tools guide this process toward the formulation of two scenarios: one “normative” and the other “exploratory”. These scenarios differ in terms of the types of vegetation added (tall, low), the locations of greening (city center, suburbs, commercial and industrial areas), and the density of the vegetation introduced. The normative scenario increases green areas to cover half of the city with low vegetation and one-quarter with trees. The exploratory scenario is closer to a realistic scenario, built from local urban planning documents (PLUi-HD) and the knowledge of metropolitan agents. It increases Dijon's low vegetation by 80%, proposing green neighborhoods up to 90%. It is characterized by the addition of large areas of low vegetation, while the normative scenario is characterized by an equivalent addition of smaller areas of both tall and low vegetation. The simulation results from Méso-NH coupled with TEB/SURFEX, when compared to the reference, show that the exploratory scenario cools air temperatures by up to -1°C, while the normative scenario leads to a reduction in UTCI (Universal Thermal Climate Index) by up to -2.5°C during the day. The methodology developed thus lays the foundation for a geospective approach to decision-support, generalizable to other territories

Full textThe major purpose of this study is a better understanding of mechanisms involved in thermal degradation of porous medium (wood for instance). Numerical and experimental investigations have been carried out. A non linear coupled differential set of equations had to be solved to describe heat and mass transfer, pyrolysis reaction and the induced solid matrix transformation. Inclusion of anisotropy has been performed using 2D-simulation. Two experimental set up have been used to investigate pyrolysis under inert and ambient atmosphere. The reactive zone has been found to be very thin compared to slab length and to propagate into the sample as time proceeds. A pyrolysis front velocity has been defined experimentally and numerically. A detailed analysis of heat and mass transfer in the sample provided an improved understanding of the front propagation mechanism. Heat conduction has been found to play a major role in the heat balance whereas chemical reactions contribution has been shown to be negligible. Under oxidative atmosphere, smoldering combustion occurs at the irradiated surface and has been shown to supply three times more heat than incident heat flux so that pyrolysis starts at lower incident heat fluxes. Inclusion of structure anisotropy leads to a paradox: pyrolysis front propagates more rapidly across than along the fibres (although heat conductivity is lower across than along fibres)

Full textThe purpose of this thesis is to develop a new methodology for the calibration and the optimization of multi-physics systems. Given the context in which the work was done, we mainly focused on hydro-electromechanic circuits of heavy goods vehicles, specifically excavators. A new approach is presented in this thesis to calibrate a complex multi-domain system. We applied this approach on two case studies: a theoretical and a real excavator’s hydro-electromechanic circuit. Results concluded that applying this approach was an efficient solution, as it proves its accuracy and efficiency with less amount of computation time. Due to their large application quantities with extremely low efficiency, pollutant emissions, high fuel consumption and oil price, researches on the environment protection and the energy saving of construction machinery, especially hydraulic excavators, have become very necessary and urgent. An overview on the energy saving principles is discussed and then classed based on the type of the energy recovered. Finally, we proposed a new approach to design the energy recovery system. To demonstrate its relevance, we applied this approach on an energy recovery patent. Results concluded that our proposed method proved its accuracy that lead to the most accurate results and the optimal design

Full textIn this thesis we establish a gluing formula of real analytic torsion forms for flat vector bundles on a smooth fibration under certain assumptions. First, we obtain the gluing formula under assumption that a fiberwise Morse function exists. Second, we use the adiabatic method to prove the gluing formula in the case that the fiberwise twisted cohomology groupes of the fibration of cutting hypersurface vanish. In this thesis we assume that the metrics admit product structures near the cutting hypersurface. We also work on the asymptotic expansions of Bergman kernel

Full textLn this thesis, we consider a vector bundle E over a compact manifold M (with an inner product and an adapted connection) and an operator: the "generalized Laplacian" which is the rough Laplacian with a potential. Then we refer to the frame bundle (a principal bundle) P associated to the vector bundle E. The equivariant functions on P with value in the fiber space correspond to the sections of E. We construct an embedding in a Hilbert space using these equivariant functions and the heat kemel. We also discuss the properties of this embedding, more precisely, the induced metric. We conclude that the embedding is asymptotically an isometry as the time t tends to O. We illustrate the study in a concrete way by studying the case of the Dirac operator. Ln the same context, we generalizesorne heat kemel estimates which lead us to demonstrate a precompacity theorem for a new spectral distance that we define. As aconsequence, we obtain a result of convergence to a limit space, with a certain number of "good properties" related to this convergence
