Повний текст джерелаThe continuous growth in telecommunication needs in our society translates into a series of technical challenges for the systems that provide such services, whether it is television broadcasting, telephone, or data exchange. The telecommunication satellites are particularly concerned by this need for innovation, both on the embarked technologies but also on the way the resulting resources are exploited for the end users. On the latter point, for a telecommunication mission defined precisely in terms of service zone, type, quantity and quality of service, one has to be able to size as adequately as possible the telecommunication satellite payload, under the several constraints it is subject to: mass, volume, cost, and power consumption of the embarked hardware. This thesis develops an algorithmic approach for a such a sizing in the particular case of the telecommunication systems that are said to be "multi-beam". A global optimization process of these satellite system is proposed. It relies on a decomposition into a set of mathematical problems whose respective complexities, reduced with respect to the original problem, allow to reasonably aim for efficient algorithmic solutions. This work allowed to identify two key problems in this satellite payload sizing, addressed through an operations research angle: the beam layout optimization and the frequency plan optimization. This first beam layout problem under payload constraints has been an occasion to propose novel ways to handle Euclidean norm constraints on continuous variables for non-convex non-linear mixed programs. These techniques have been then successfully applied in for the generation of solutions to this first problem that fully exploits the mixed integer linear programming formalism. Then, a novel exploitation of some of the properties of the k-means clustering has been proposed as it allows to simplify these mathematical models and therefore accelerate the beam layout optimization. These mathematical programming algorithms have been then compared to a greedy heuristic developed during this thesis work. The second central sizing problem that has been identified is the frequency plan definition. It consists in a resource allocation of on-board satellite resources to the several beams that have been defined in the preceding beam layout optimization problem. With an objective of minimizing the number of a certain type of hardware to be embarked on the payload, the satisfaction of the telecommunication mission defined by an individual demand of all the end users on the ground is aimed. This complex problem itself lead to a decomposition into two sub-problems of frequency and on-board payload hardware allocation, that are treated with constraints programming and integer linear programming, exploiting theoretical results that are useful both at the problem modeling and problem solving levels

Повний текст джерелаSpace launchers undergo a certain amount of complex excitations during their lifecycle. These excitations are transmitted to the payload in a structure-born or air-born way. To improve the dynamic behaviour and thus ensure the protection of the payload, secondary systems must be added to the launcher – indeed, the architecture of the launcher is fixed at the beginning of the project. The essential part of this thesis work is dedicated to the optimal fitting of a system capable of reducing the vibration response of the payload, using appropriate models. Therefore a double modal synthesis method is implemented, allowing to calculate the vibrational response of the structure with reduced bases and offering improved performances over conventional methods. The addition of a local damping device requires the consideration of one or more structural modifications in the model, a dedicated method is thus developped along with a specific continuation algorithm. A friction damper is retained, a prototype is designed and built. It is first characterized alone ; the identified behaviour is that of a spring in series with a dry friction element, a simple Coulomb friction law enables to reproduce the experimental curves. A scale model of the launcher’s last stage is designed and built. The friction device is then mounted inside the scale model and leads to a significant reduction of the payload vibration levels

Повний текст джерелаThe filters and the output multiplexers of payload of satellite are in the beginning of improvement of performance, time of design and time of realization. The research tasks presented here are on the development of methods of assistance to the electromagnetic design of these devices. The methods of assistance to the electromagnetic design of the filters, used and developed here, make it possible, on the one hand, to obtain final dimensions of the filters for an experimental realization (machining only one set of cavities and irises). They also make it possible to characterize quickly and efficiently the filters in an electromagnetic way. These methods were validated by the design of two filters in dual-mode cavities functionning in Ku-band and in Ka-band and were validated with experimental results. The electromagnetic characterization of the filters permits to consider the analysis of multiplexers. It was at the origin of the development of methods of assistance to the electromagnetic design of multiplexers. The methods presented contribute to the conception of multiplexers by modelling the dephasing introduced the excitation systems. The second axis presented permits to compensate for the influence of spurious modes disturbing the response of the OMUX. Then, these methods make it possible to consider a fast and rigorous electromagnetic characterization of multiplexers and thus, to answer the problems involved in the growing number of channels which constitute it

Повний текст джерелаThis thesis is a research in methodology of evaluation of the professional practices. The original approach consists in proposing a method making it possible to achieve a double goal: on the one hand to immediately use the results for the benefit of the patients included in the evaluation and on the other hand to answer the obligation of evaluation of the professional practices such as she is currently recommended by the High Authority of Health (HAS). Continuing a work initiated on the methodology of the investigations of practices applied to the evaluation of the practices of care, and within the framework of the Grouping of Public Interest "ReQua" of Franche-comté, we checked with studies on various topics (psychiatry, nutrition, geriatrics) that an evaluation of the occupational practices pursuing the double goal describes higher, feasible, acceptable by the professionals and was recognized by the HAS
