Power Hardware In Loop (PHIL) simulation is a test method where equipment intended for field application can be debugged and tested in the factory by connecting to a virtual power system model simulated on a real-time simulator. Hence the PHIL simulation may be very effective in developing, debugging and commissioning power equipment. However, due to imperfections (e.g., time delay, noise injection, phase lag, limited bandwidth) in the power interface, simulations in this method show errors or even instable results. This thesis presents means to improve the simulation accuracy of the PHIL simulation. In order to achieve this, a simulation model is constructed for the PHIL simulation process itself. Using simulation, the sensitivity of the simulation to parameters in the interface equipment as well as interface software is thoroughly investigated. One interesting result is that the simulation is significantly affected by phase delay. Based on the analysis, an improved algorithm that uses additional interface filters (implemented in hardware and/or software) is proposed. The thesis shows that more stable and accurate results can be obtained by using the new algorithm. The validity of the proposed methods is verified through a simulation based study and hardware based studies.

This master's thesis deals with the analysis and presentation of the global company Nike, especially the perception of the brand as a symbol of basketball. The master's thesis is divided into two parts. The first part describes the theoretical and methodological starting points, particularly the international marketing environment, concepts and strategic approaches, international marketing mix, plus the event marketing and sponsorship, which are an integral part of Nike marketing. The practical part describes the Nike company both from an international perspective, and marketing activities in the domestic environment. Based on the information and the survey, conducted gives recommendations for marketing activities in the basketball category in the domestic market.

L’intégration des énergies renouvelables a conduit à introduire la notion d’utilisation locale de ces nouvelles sources de production. Nous pouvons définir le paradigme de microréseau comme une agrégation de plusieurs sources d'énergie distribuée qui peuvent alimenter leurs charges locales. Ces microréseaux peuvent être îlotables pour garantir la continuité de service et l’alimentation des charges. Pour assurer la fiabilité du réseau, une stratégie de protection des générateurs et du microréseau lui-même a été proposée. Dans ce mémoire, les points communs et les différences entre les générateurs classiques et les générateurs connectés au réseau à l’aide de convertisseur d’ d’électronique de puissance sont présentés. Ensuite, nous présentons la conception d’une source de tension à base d’une micro-turbine à gaz comme source d’énergie primaire contrôlable. Nous étudions les possibilités pour le générateur de demeurer connecté dans les conditions du creux de tension (fault-ride-through) tout en étant protégé contre les surintensités. Nous avons proposé deux solutions différentes permettant de limiter ces courants du générateur. De plus, pour assurer la continuité d’alimentation des charges en deux modes de fonctionnement, nous avons intégré un détecteur de l’ilotage basé sur le relais ROCOF dans le système de commande du générateur. Une validation expérimentale pour ces travaux a été réalisée en utilisant la simulation temps réel PHIL. Finalement, un plan de protection coordonnée valide dans les deux modes de fonctionnement et avec les différents types de source est présenté. Cette stratégie a été testée sur un exemple de microréseau simulé sur le simulateur temps réel / The integration of renewable energy has led to introduce the concept of local use of these new production sources. We can define the Microgrid paradigm as an aggregation of several distributed power sources that can supply their local charges. These microgrids may be islanded to ensure the continuity for supplying the loads in both operation modes. To provide the reliability of the network, a strategy to protect the generators and the Microgrid itself has been proposed. In this thesis, the similarities and differences between conventional generators and the generators connected to the network using the power electronics converter are firstly presented. Then, we present the design of a voltage source connected by a power electronic converter and LC filter, based on gas micro-turbine as the controllable primary energy source. We study the possibilities for the generator to remain connected in case of voltage sags (fault-ride-through) while being protected against the overcurrents. We have proposed two different solutions to limit these generator currents. In addition, to ensure continuity of supply the loads in two operation modes, we integrated an islanding detector based on the ROCOF (Rate Of Change Of Frequency) relay in the control system. An experimental validation for this work was realized using PHIL (Power Hardware in the Loop) real-time simulation. Finally, a coordinated protection plan valid in both operation modes and with different types of sources was presented. This strategy was tested on a simulated example of microgrid on real-time simulator

Notre travail vise à étudier les Max-Phil, textes inédits de Kurt Gödel, dans lesquels il développe sa pensée philosophique. Nous nous intéressons plus spécifiquement à la question du réalisme conceptuel, position déjà défendue dans ses écrits publiés selon laquelle les concepts existent indépendamment de nos définitions et constructions. L’objectif est de montrer qu’une interprétation cohérente de ces textes encore peu connus est possible. Pour ce faire, nous proposons une interprétation de certains passages, interprétation hypothétique mais susceptible d’apporter de nouveaux éléments à des questions laissées sans réponse par les textes publiés, telles celles relatives au réalisme conceptuel. Cette dernière position ne peut être comprise que par un éclairage de la notion de concept chez Gödel. Les concepts sont des entités logiques objectives, au cœur du projet d’une théorie des concepts conçue comme une logique intentionnelle et inspirée de la scientia generalis de Leibniz. L’analyse des Max-Phil souligne que la notion de concept et la primauté du réalisme conceptuel sur le réalisme mathématique ne peuvent se comprendre qu’à la lumière du cadre métaphysique que se donne Gödel, à savoir d’une monadologie d’inspiration leibnizienne. Les Max-Phil offrent ainsi des indices sur la façon dont Gödel reprend et modifie la monadologie de Leibniz, afin, notamment, d’y inscrire les concepts. L’examen de ce cadre métaphysique tend également à éclaircir les rapports entre les concepts objectifs, les concepts subjectifs (tels que nous les connaissons), et les symboles (par lesquels nous exprimons les concepts), mais aussi les rapports entre logique et mathématiques. / Our work aims at studying the unpublished texts of Kurt Gödel, known as the Max-Phil, in which the author develops his philosophical thought. This study follows the specific issue of conceptual realism which is adopted by Gödel in his published texts (during his lifetime or posthumously), and according to which concepts are independent of our definitions and constructions. We want to show that a consistent interpretation of the Max-Phil is possible. To do so, we propose an interpretation of some excerpts, which, even if it is only hypothetical, can give new elements in order to answer open questions of the published texts, e.g. questions about conceptual realism. This last position is not understandable without explaining Gödel’s notion of concept. For him, concepts are logical and objective entities, and they are at the core of a theory of concepts, which is conceived as an intensional logic, following Leibniz’s scientia generalis. The analysis of the Max-Phil underlines that we can understand the notion of concept and the primacy of conceptual realism over mathematical realism only in the light of Gödel’s metaphysical frame, i.e. of a monadology inspired by Leibniz. Thus the Max-Phil shows how Gödel reinvestigates Leibnizian monadology, and offers some clues on the modifications he makes on it in order to include concepts. The examination of this metaphysical frame tends to elucidate the relationships between objective concepts, subjective concepts (as we know them) and symbols (through which we express concepts), and also the relationship between logic and mathematics.

This thesis deals with analysis and implementation of Power-HIL system that is designed to simulate real DC motor with comutator and permanent magnets. For problem analysis were used simulations of real components in Matlab / Simulink. The electronic parts of system were simulated with using the SimElectronic library. Idividual hardware components were designed according to simulation results. The outcome of this thesis is a power electronic simulator of real DC motor, which is implemented on dSPACE platform. The system allows software to setup parameters and behavior of simulated motor. The final system can be used for testing DC motor ECU (electronic control units).
