Full textThis research considers the "social space of habitat" as one of the main factors involved in social and professional insertion pricesses, and more generally in construction of social identities. The poulation is constituted by urban and rural youngs registered in six different "missions locales" for insertion, in west of france. If they all have a low level of qualification and below to the working classes, they have different school background and degree of insertion. The social space of habitat yields the combination of different independant variables such as socio-professional categories of the parents, school attentance, insertion, geographics moves. The analysis of social and geographic cursus of the families allows to distinguish six types of insertion linked to their global social trajectories. In that sence, we believe that the social space of habitat appears as one of the most important factor of socialization

Full textThe work addresses two space trajectories optimization problems : the flight of a launcher upper stage and the collecting of space debris. For these two problems the goal is to develop resolution methods and softwares usable in an industrial framework. Flight of a launcher upper stage. For the problem of a launcher upper stage flight, two continuation approaches are envisioned from models simplifications. The first approach consists in solving the flat Earth problem with uniform gravity, then to come back to the round Earth problem through a double continuation on the gravity and on the earth curvature. The second approach consists in solving the impulsive problem, corresponding to an infinite thrust level, then to come back to the continuous thrust problem through a continuation on the thrust level. The goal is to define a solving procedure as automatic as possible for various instances of the real problem : launcher configuration, targeted orbit. Space debris collecting. The selection of the debris and the visiting order is a shortest path problem in a time-dependent valuated graph. A generic strategy reduces the optimal control problem to a nonlinear programming problem of finite dimension, which can be coupled to the path problem. A local linearization around an initial solution allows to set up a Branch and Bound algorithm. The reference solution is then updated with the linearized solution. Iterating on the linearization-resolution process from the pre-optimized initialization allows converging to the solution of the global problem

Full textIn 1957, the space conquest by man began with the successful launch into orbit of the first artificial satellite; Sputnik 1. This was the beginning of the exploitation of the earth's orbit characterized by a hundred of rocket launches starting from several launchpad such as Kourou or Baikonur. Today, the Earth's orbit has a population composed mostly of space debris. These include upper rocket stages, satellites which have ended their mission and other small artificial objects whose origin is not necessarily recognizable. Their number has become so important that it question the sustainability of space activities. In this thesis we figure out the difficulties to handle the issue posed by the space debris. In the first part of the thesis, we develop a fragmentation model to generate clouds of space debris as a result of an explosion or collision in space. For this, we mainly used the fragmentation model of NASA, Evolve, and other distribution functions from diverse experiences of fragmentation. Thanks to this model, we know the geometric parameters and also in terms of speed which we will seek to determine their influence on the movement of the cloud. Thus, in the second part of the thesis, we study the motion of space debris evolving initially in low Earth orbit

Full textRecent advances made in the fiel of autonomous vehicles suggest that, in a near future, Unmanned Air Vehicles (UAVs) will be more and more deployed in order to achieve various missions (such as surveillance, intelligence or search and rescue). Moreover, since UAVs may be slow, the impact of current is significant and cannot be neglected. That is why we introduce in the proposed thesis two new trajectory planning algorithms in presence of currents, which are extensions of wavefront expansion techniques. The first one, called sliding wavefront expansion, allows to handle strong currents, i. E. Currents which are faster than the UAV. We show that this approach is much more reliable than the existing one, which can return, in this particular context, physically infeasible paths. The second one, called symbolic wavefront expansion, allows to handle time-varying currents. Given some weather forecast (through current charts), this approach determine both the departure time and the trajectory minimizing the UAV’s travel time

Full textRecent space missions rely more and more on the cooperation between different spacecraft in order to achieve a desired objective. Among the spacecraft proximity operations, the orbital rendezvous is a classical example that has generated a large amount of studies since the beginning of the space exploration. However, the motivations and objectives for the proximity operations have considerably changed. The need for higher autonomy, better security and lower costs prompts for the development of new guidance and control algorithms. The presence of different types of constraints and physical limitations also contributes to the increased complexity of the problem. In this challenging context, this dissertation represents a contribution to the development of new spacecraft guidance and control algorithms. The works presented in this dissertation are based on a structural analysis of the spacecraft relative dynamics. Using a simplified model, a new set of parametric expressions is developed for the relative motion. This parametrization is very well suited for the analysis of the geometric properties of periodic relative trajectories and for handling different types of state constraints. A formal connection is evidenced between the set of parameters that define constrained trajectories and the cone of positive semi-definite matrices. This result is exploited in the design of spacecraft relative trajectories for proximity operations, in the impulsive control framework. The resulting guidance algorithms enable the guaranteed continuous constraints satisfaction, while still relying on semi-definite programming tools. The problem of the robustness of the computed maneuvers with respect to navigation uncertainties is also addressed

Full textTo remain competitive, manufacturers need to reduce the costs and development times of their new products. Current products are increasingly integrated, smaller, lighter and more energyefficient. They are more difficult to design and have to be assembled, maintained and disassembled under very high geometric constraints. Traditionally, during the design phase, the CAD model of the product is established, then the physical parts of the product are manufactured, to discover all too often that some or all of the tasks associated with the product's life cycle are difficult or impossible to carry out. If these problems are detected too late, the product design has to be reconsidered. The aim of this thesis is to validate, at the design stage, all the tasks associated to the PLM using digital simulation before the physical prototypes are manufactured. This would make it possible to reduce development times and costs and to aim for more environmentally-friendly manufacturing processes by reducing the number of physical prototypes manufactured. A key step in the simulation-based validation of PLM tasks is to find a feasible collision-free trajectory in order to prove their feasibility. Since the 1980s, the robotics community has been using automatic path planning methods to solve this problem. However, these methods have limitations, mainly linked to the complexity of the environment models, which are traditionally purely geometric. In very complex environments, path planners can propose trajectories that are not very relevant, in times that can be very long, or even fail. To overcome these limitations, some works has considered collaborative human-planner approaches, but these rarely enable continuous interaction. On the other hand, VR techniques allow simulation with a human operator in the loop, immersed in the virtual environment and interacting with it. An original approach linking automatic path planning and VR has been developed at LGP, taking advantage of the computing power of computers and the cognitive abilities of a human operator. However, in this approach, the assistance offered to the operator is not oriented towards the task to be carried out. In order to be able to reason at the level of the task to be carried out, task planning and path planning must be considered together, and attention must be paid to the ability to model information relating to the task and to reason about these information; ontologies are a promising tool. The aim of this thesis is to develop a common framework for the semantic coupling of path and task planners for manipulation assistance in VR or robotics. Within this framework, we propose two main contributions: The first contribution of this work proposes two original ontologies. The first, ENVOn-2, concerns the modelling of the environment in which a manipulation task takes place. The second, TAMPO, is an ontology developed for jointly use path and task planning. The second contribution concerns the development of a methodology for the semantic coupling of task and trajectory planners. This methodology, through the joint use of the two ontologies, makes it possible to improve the path planning of a primitive action while proposing a task plan (or plans) that is (are) relevant to the manipulation being carried out. These developments were then validated using a variety of scenarios of increasing complexity. The results obtained demonstrate the relevance of the approach
