Abstract:
Currently, power system operation and control with AGC are undergoing fundamental changes due to rapidly increasing amount of renewable sources, energy storage system, restructuring and emerging of new types of power generation, consumption and power electronics technologies. Continuous growth in size and complexity, stochastically changing power demands, system modeling errors, alterations in electric power system structures and variations in the system parameters over the time has turned AGC task into a challenging one.

Abstract:
Since the early days of software testing, automatic test generation has been suggested as a way of allowing tests to be created at a lower cost. However, industrially useful and applicable tools for automatic test generation are still scarce. As a consequence, the evidence regarding the applicability or feasibility of automatic test generation in industrial practice is limited. This is especially problematic if we consider the use of automatic test generation for industrial safety-critical control systems, such as are found in power plants, airplanes, or trains.

Ce travail est développé dans le contexte des projets SESAR et Next-Gen, où de nouvelles applications de la gestion du trafic aérien (ATM) comme le concept de gestion d'opérations en 4D, se sont focalisées sur les opérations basées sur la trajectoire (TBO - Trajectory Based Operations). Ces opérations sont en relation avec l'extension de la flexibilité de la séparation entre avions, et par conséquence, avec l'augmentation de la capacité du trafic aérien. En sachant qu'une évolution des routes fixes et autorisations émises par le contrôle du trafic aérien (ATC - Air Traffic Control) vers des tr

Abstract:
The main topic of this thesis is the trajectory generation for the autonomous layout entering of an automated guided vehicle in an indoor environment. I specifically studied a control model for a quadricycle vehicle. The thesis is structured in four chapters. The first chapter illustrates the Shark vehicles produced by System Logistics S.p.a.. In particular, the chapter is centred on the explanation of kinematic model of quadricycle vehicle, introducing also a brief explanation of what is a layout and an introduction of what is the operating system that control the process (QNX).

Abstract:
Le développement des logiciels avioniques les plus critiques, comme les commandes de vol électriques, présentent plusieurs contraintes qui peuvent être quasiment contradictoires – par exemple, performance et sûreté – et toutes ces contraintes doivent être respectées simultanément. L'objective de cette thèse est d'étudier et de proposer des évolutions dans le cycle de développement des logiciels de commande de vol chez Airbus afin d'améliorer leur performance, tout en respectant les contraintes industrielles existantes et en conservant des processus de vérification au moins aussi sûrs que ceux

Abstract:
L'optimisation multi-objectif concerne la résolution de problèmes pour lesquels plusieurs objectifs (ou critères) contradictoires sont pris en compte. Contrairement aux problèmes d'optimisation ayant un seul objectif, un problème multi-objectif ne possède pas une valeur optimale unique mais plutôt un ensemble de points appelés "ensemble non dominé". Les bornes inférieures et supérieures d'un problème multi-objectif peuvent être également décrites par des ensembles. Dans la pratique, les variables utilisées en optimisation multiobjectif représentent souvent des objets non fractionnables et on p

Abstract:
<p>Sectra Communications AB has developed a terminal for encrypted communication called the Tiger platform. During voice communication delays have sometimes been experienced resulting in conversational complications.</p><p>A solution to this problem, as was proposed by Sectra, would be to introduce voice activity detection, which means a separation of speech parts and non-speech parts of the input signal, to the Tiger platform. By only transferring the speech parts to the receiver, the bandwidth needed should be dramatically decreased. A lower bandwidth needed implies that the delays slowly sh

Abstract:
The thesis is focused on the information and communication technologies used in the energetic. Problematic areas in energetic which are regulation, metering, control of waste minimalizations, expense and maximalization of earnings. These aspects lead to implementing expert systems, which have to process this bulk of information necessary for increasing efficiency and economization of single processes. Systems used in practice have their own hierarchical structure, where every application requires specific access of selection of used components that suit to the application. First of all it is a

Aujourd'hui, les réseaux de communications sont largement utilisés pour relier les points de ressources, qui permettent la transmission de données à distance, de réduire la complexité dans le cadre de câblage et les coûts de support et de fournir l'aise dans la maintenance. En raison de ces avantages, les réseaux ont été introduits dans les systèmes automatiques au cours de ces dernières décennies et de nouveaux protocoles de réseau industriel ont été également développés pour assurer le contrôle à distance.

Dans les années 90, la commission européenne a sollicité la mise au point d'un système de contrôle commande et de signalisation ferroviaire commun à tous les réseaux des états membres : le système ERTMS " European Railway Traffic Management System ". Il s'agit d'un système réparti complexe dont le déploiement complet est long et coûteux. L'objectif global consiste à diminuer les coûts de validation et de certification liés à la mise en œuvre de ce nouveau système en Europe.
