Full textThis thesis presents a study of the sensitivity of nanoelectronic devices based on Silicon On Insulator technology to ionizing rticles of terrestrial and space environments. The overall context of the study is described as weil as the main radiation¬luced effects in electronic devices. It is shown that total ionizing dose and transient radiation effects have to be restigated. Concerning the total ionizing dose effects, the physical mechanisms explaining the degradation of transistors ~ctrical characteristics are discussed as a function of device architecture and design. After that, the transient radiation response of single- and multiple-gate devices is investigated. Furthermore, mixed-mode simulations are used to show trends as a function of the integration level on the sensitivity to single-event effects. From our study, we propose some ways to optimize devices and to mitigate the radiation induced effects in future technologies

Full textThe growth of the transport by land network in europe raises many questions about the protection of the environment. European law provides some answers, including the provision of legal instruments to include the environment in decision process. In 1985, the community institutions adopted the council directive 85 337 on the environmental assessment of some private and public projects. This was the first step tpwards the integration of environmental concerns into the approval procedure of road and railway projects. This directive is, however, limited to the project level; the environment is therefore not taken into consideration during the decision stage. The european community has already intervened in community financing procedures of roads and railways regarding environmental matters. They now have to intervene during the initial stage of the decision-making process, that is, at the level of plans, politics and programmes which concern national and european transport networks

Full textAlthough dissolved organic matter (DOM) represents a small fraction of soil organic matter (OM), it is involved in many biogeochemical processes in the environment. Its composition reflects its sources of production, and the processes it has been exposed to. However, the processes taking place immediately after DOM production are still poorly understood, due to its high reactivity. In terrestrial environments, fresh leaf litter is one of the major initial sources of DOM, before it is degraded. This PhD focused on the characterisation of DOM produced by different vegetation species, and the evolution of their properties during biodegradation. The relationship between the composition of vegetation cover and the molecular signature of DOM has been assessed, in order to determine the influence of vegetation on DOM properties in the environment. The water extractable OM (WEOM) produced by 6 vegetation species (C. stellaris, F. nivalis, E. vaginatum, B. nana, B. pubescens, and Salix sp.) were characterised through complementary analytical technics. The results showed that the quantity and composition of WEOM produced by vegetation were different between plant functional types (PFT). It was also pointed out that some proxies commonly used to characterise DOM were not relevant to the study of unprocessed WEOM. However, the comparison of relevant proxies indicated that graminoids were potentially less biodegradable than lichens, but more than shrubs. WEOM biodegradation experiments were carried out under controlled conditions. For this purpose, 4 species belonging to different PFT were selected, and their WEOM extracted. These species were C. stellaris (lichen), E. vaginatum (sedge), A. polifolia (dwarf evergreen shrub), and B. nana (deciduous dwarf shrub). The results showed a significantly higher consumption of WEOM produced by C. stellaris and E. vaginatum, than A. polifolia and B. nana, at the end of the experiment. In the meantime, the accumulation of recalcitrant compounds in WEOM was observed, especially for B. nana. These results put into light a more important biodegradability of lichens and graminoids compared to shrubs. Furthermore, the molecular diversity of WEOM significantly decreased for C. stellaris and E. vaginatum, whereas it increased for B. nana. Species-specific biodegradation processes have been brought to light. Finally, samples of DOM were collected from Arctic ecosystems with contrasted vegetation cover compositions. DOM samples were analysed by high resolution mass spectrometry (HRMS). Their molecular signatures were compared to each other, and to WEOM produced by vegetation. A great amount of compounds were common to all DOM samples. Despite these ubiquitous compounds, it was possible to discriminate ecosystems, based on the molecular compositions of their DOM. The contributions of each species to the vegetation cover were compared to the contributions of their WEOM to the molecular signature of DOM. These comparisons showed a significant positive correlation for B. nana, but not for other studied species. The results of this thesis show that the quantity and composition of produced WEOM are vegetation-specific. Consequently, WEOM biodegradability is also vegetation-specific. Therefore, the DOM produced by different vegetation species won’t have the same dynamic in the environment. Furthermore, the WEOM produced by vegetation are homogenised during their biodegradation

Full textThis thesis is a contribution to the structural health analysis of the body of ground military vehicles. Belonging to the 20 - 30 tons range, such vehicles are deployed in a variety of operational contexts where driving conditions are severe and difficult to characterize. In addition, due to a growing industrial competition, the mobility function of vehicles is acquired from suppliers and is no longer developed by Nexter Systems. As a result, the complete definition of this function is unknown. Based on this context, the main objective of this thesis is to analyze the health of the vehicle body using a probabilistic approach in order to control the calculation techniques allowing to take into account the random nature of loads related to the use of ground military vehicles. In particular, the most relevant strategies for propagating uncertainties due to the terrain within a vehicle dynamics model are defined. This work describes how it is possible to manage an observation data measured in the vehicle for the purpose of assessing the reliability with respect to a given damage criterion. An application on a demonstrator entirely designed by Nexter Systems illustrates the proposed approach

Full textThe present research project involves the partial development of a two-phase fluid loop for spatial applications. The state-of-the-art of the two-phase flow research for spatial applications is reviewed. This review in turn allows for a general understanding of two-phase flow phenomena in microgravity situations and of the evaporator, condenser, pressure-regulating reservoir and pumping system design. Next, the setting up of a 600 W loop for ground level testing with ammonia as the working fluid is described. The experimental results for the two-phase flow configurations and pressure drops in the adiabatic region between the evaporator and the condenser are presented and analyzed, as well as the heat transfer coefficient in the evaporator and in the condenser. The proper system operation is so verified as well as the influence of two-phase parameters on its thermal performance. The development of a semi-empirical model of the transport phenomena in the condenser is then presented. In this regard, a preliminary literature survey of existing flow maps for ground level and microgravity applications allowed for the selection of the one most suit able for the present study. The condensation heat transfer inside smooth tubes is modeled for the case of stratified and annular flow using different methods for the calculation of the pressure drops and the void fraction. A comparison between experimental and analytical results then made it possible to choose the method most appropriate for the range of flow parameter tested. Finally, the influence of quality, mass flow rate and tube diameter on the condensation heat transfer and the length of the condensation region is presented
