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

No movimento entre as imagens de ?ros na tradi??o e a retomada desse discurso do passado na s?rie de elogios ao amor deste di?logo, pretendemos fixar um aspecto inconteste para Plat?o, o pensar o amor como uma pot?ncia que se sobrep?e e at? mesmo se confunde com a no??o de desejo, a julgar pelo Fedro, no qual o amor ? definido como desejo. No Banquete, esse desejo ? direcionado para apreens?o do belo, como observamos na ascese er?tico-dial?tica de Diotima, contudo isto n?o significa o rompimento com o desejo inato, como defendem alguns de seus int?rpretes. No redirecionamento do desejo da dimens?o apetitiva para a dimens?o puramente intelectiva da alma, Plat?o concilia a ambiguidade do fil?sofo como um ser intermedi?rio entre duas ordens distintas e afins de desejos, o do corpo e o da alma, na representa??o de ?ros como um da?mon. Nessa circularidade entre esferas aparentemente inconcili?veis entre si, as imagens de ?ros transparecem na escrita po?tico-filos?fica de Plat?o, sob a forma de um discurso de natureza acentuadamente er?tica. / La lecture du Le Banquet nous a incit?s ? penser ? l?image d??ros identifi? de mani?re propre et g?nuine ? Platon de concevoir la repr?sentation du philosophe. Dans le mouvement entre les images d??ros dans la tradition et la reprise de ce discours du pass? dans la s?rie d??loges ? l?amour de ce dialogue, nous voulons fixer un aspect absolu pour Platon, penser l?amour comme un pouvoir qui se superpose et m?me se confond avec la notion de d?sir, ? en juger par Ph?dre, dans lequel l?amour est d?fini comme un d?sir. Dans Le Banquet, ce d?sir est dirig? vers l?appr?hension du beau, comme nous pouvons remarquer dans l?asc?se ?rotico-dialectique de Diotime. Par contre cela ne signifie pas la rupture avec le d?sir inn?, comme celui que d?fendent quelques interpr?tes. Dans la redirection du d?sir de la dimension app?titive ? la dimension purement intellective de l??me, Platon concilie l?ambig?it? du philosophe comme un ?tre interm?diaire entre deux ordres li?s et distincts du d?sir, du corps et de l??me, dans la repr?sentation d??ros comme un da?mon. Entre ces deux sph?res en mouvement apparemment inconciliables entre elles, les images d??ros apparaissent sur l??crit po?tico-philosophique de Platon, sous la forme d?un discours de nature fortement ?rotique.

The relationship between performer and spectator is a constant topic in theatre since audiences are essential to any performance. Some contemporary performances strive to blur the line between the two by allowing audiences to participate during the show. Often, audience participation is despised and therefore avoided by spectators and theatre practitioners. However, Blue Man Group thrives on it due to their authentic character, adaptable narrative, and accessible space. Through my examination of the show as an audience member, I theorize that these three elements control the audience's willingness to participate in the production and in turn make the entire experience more rewarding and memorable as performer and spectator share roles in order to create this performance. Chris Wink, Matt Goldman, and Phil Stanton co-founded Blue Man Group in 1987, and received their first official venue in 1991. Blue Man Group is a ninety-minute variety show that utilizes rock music, theatrical vignettes, and experiments with science, art, and modern technology to explore the ways in which humans express and communicate. This unprecedented show performs in multiple locations daily throughout the United States, Germany, and has also captivated audiences of all ages around the world. The most popular and recognizable element to the show is the humanoid Blue Man character. He does not speak or make large facial expressions. Instead, he mainly observes intently and follows commands, much like a spectator. His original physical attributes, honest behavior and communication, and authoritative presence through three performers grant him authenticity. His unique personality draws in an audience's interest and investment in the character and the entire production. The co-founders identify the Blue Man Group adaptable narrative as “Neo-Vaudeville”, mixing many forms of science and art together. The cast, crew, and audience take part in the show through tribal training, developing communitas as they watch and learn, call and respond, to the show's commands. The pieces that contain audience participation utilize various types of invitation, coaxing audiences into participation in effective ways. Through an exploration of visual and aural perception, spatial fluidity, and technology, Blue Man Group's use of space connects its audiences to the performance and helps them consider more deeply their connections with others. Thus people often participate during the show and enjoy doing so. This level of investment and excitement is necessary for successful audience participation. Thus Blue Man Group is a blue print for how live theatre can form a powerful relationship with audiences.

In this thesis a Power-Hardware-in-the-Loop (PHiL) test rig is developed forhydro-pneumatic suspension by utilizing the physical suspension unit together with asimulated vehicle model in MATLAB Simulink. Power-Hardware-in-the-Loop is the termfor combining simulation models with power-transmitting hardware components inreal-time. This is useful when a system contains some parts that are complex and somethat are simpler to model. The simple parts of the system can be modelled andsimulated in conjunction with more complex parts consisting of physical objects. Thereason for keeping the items to be tested as physical components is their complexity andunknown characteristics that can be difficult to estimate. By utilizing PHiL, vehiclecomponents can be tested and developed without the need for the actual vehicle, whilekeeping the characteristics that the physical vehicle would bring. The process included development of a real-time enabled vehicle model, evaluation ofcontrol strategies as well as selection of hardware used for a small scale test rig. The project resulted in a functional small scale single wheel test rig. Validationexperiments confirmed that the rig produced results close to expectations. Thecommunication between the the test rig and the simulated model was accurate andshowed the potential for a full scale test rig. It can be concluded that a PHiL test rigcan be a suitable option to full vehicle testing. The vehicle model is fully customisable,so that the suspension units can be tested in various configurations of vehicles.

This work demonstrates the capability of a power electronic based power hardware-inthe- loop (PHIL) platform to emulate electric machines for the purpose of a motor drive testbench with a particular focus on induction machine emulation. PHIL presents advantages over full-hardware testing of motor drives as the PHIL platform can save space and cost that comes from the physical construction of multiple electric machine test configurations. This thesis presents real-time models that were developed for the purpose of PHIL emulation. Additionally, real-time modeling considerations are presented as well as the modeling considerations that stem from implementing the model in a PHIL testbench. Next, the design and implementation of the PHIL testbench is detailed. This thesis describes the design of the interface inductor between the motor drive and the emulation platform. Additionally, practical implementation challenges such as common mode and ground loop noise are discussed and solutions are presented. Finally, experimental validation of the modeling and emulation of the induction machine is presented and the performance of the machine emulation testbench is discussed. / Master of Science / According to the International Energy Agency (IEA), electric power usage is increasing across all sectors, and particularly in the transportation sector [1]. This increase is apparent in one's daily life through the increase of electric vehicles on the road. Power electronics convert electricity in one form to electricity in another form. This conversion of power is playing an increasingly important role in society because examples of this conversion include converting the dc voltage of a battery to ac voltage in an electric car or the conversion of the ac power grid to dc to power a laptop. Additionally, even within an electric car, power converters transform the battery's electric power from a higher dc voltage into lower voltage dc power to supply the entertainment system and into ac power to drive the car's motor. The electrification of the transportation sector is leading to an increase in the amount of electric energy that is being consumed and processed through power electronics. As was illustrated in the previous examples of electric cars, the application of power electronics is very wide and thus requires different testbenches for the many different applications. While some industries are used to power electronics and testing converters, transportation electrification is increasing the number of companies and industries that are using power electronics and electric machines. As industry is shifting towards these new technologies, it is a prime opportunity to change the way that high power testing is done for electric machines and power converters. Traditional testing methods are potentially dangerous and lack the flexibility that is required to test a wide variety of machines and drives. Power hardware-in-the-loop (PHIL) testing presents a safe and adaptable solution to high power testing of electric machines. Traditionally, electric machines were primarily used in heavy industry such as milling, processing, and pumping applications. These applications, and other applications such as an electric motor in a car or plane are called motor drive systems. Regardless of the particular application of the motor drive system, there are generally three parts: a dc source, an inverter, and the electric machine. In most applications, other than cars which have a dc battery, the dc source is a power electronic converter called a rectifier which converts ac electricity from the grid to dc for the motor drive. Next, the motor drive converts the dc electricity from the first stage to a controlled ac output to drive the electric machine. Finally, the electric machine itself is the final piece of the electrical system and converts the electrical energy to mechanical energy which can drive a fan, belt, or axle. The fact that this motor drive system can be generalized and applied to a wide range of applications makes its study particularly interesting. PHIL simplifies testing of these motor drive systems by allowing the inverter to connect directly to a machine emulator which is able to replicate a variety of loads. Furthermore, this work demonstrates the capability of PHIL to emulate both the induction machine load as well as the dc source by considering several rectifier topologies without any significant adjustments from the machine emulation platform. This thesis demonstrates the capabilities of the EGSTON Power Electronics GmbH COMPISO System Unit to emulate motor drive systems to allow for safer, more flexible motor drive system testing. The main goal of this thesis is to demonstrate an accurate PHIL emulation of a induction machine and to provide validation of the emulation results through comparison with an induction machine.

This thesis covers the development of complex HIL simulator for the fifth car door. The beginning of the thesis is dedicated to theoretical research in the area of In-the-Loop testing. Practical part describes development of HIL simulator complemented by power electronics part. A simulation environment Matlab/Simulink was used for control design and analysis. Before the beginning of the work was measured signal part of control unit and specific signal sequences were identified. The control was applied on sbRIO device from National Instruments company with the implementation of a model on FPGA. Specific requirements for sensing speed and generation of communication signals lead to creation of unique hardware for application needs. The result of the thesis is complex HIL simulator with intuitive GUI and possibility of simulations a wide range of DC motors.

This dissertation primarily concerns performance aspects in compositions for piano and tape, using three specific works as the basis for discussion: Larry Austin's Sonata Concertante, Thomas Clark's Peninsula, and Phil Winsor's Passages. These compositions are representative of the medium as a whole, yet each offers its own unique set of performance problems.

Geologic mapping in the Phil Pico Mountain quadrangle and analysis of the Carter Oil Company Carson Peak Unit 1 well have provided additional constraints on the erosional and uplift history of this section of the north flank of the Uinta Mountains. Phil Pico Mountain is largely composed of the conglomeratic facies of the early Eocene Wasatch and middle to late Eocene Bridger Formations. These formations are separated by the Henrys Fork fault which has thrust Wasatch Formation next to Bridger Formation. The Wasatch Formation is clearly synorogenic and contains an unroofing succession from the adjacent Uinta Mountains. On Phil Pico Mountain, the Wasatch Formation contains clasts eroded sequentially from the Permian Park City Formation, Permian Pennsylvanian Weber Sandstone, Pennsylvanian Morgan Formation, and the Pennsylvanian Round Valley and Mississippian Madison Limestones. Renewed uplift in the middle and late Eocene led to the erosion of Wasatch Formation and its redeposition as Bridger Formation on the down-thrown footwall of the Henrys Fork fault. Field observations and analysis of the cuttings and lithology log from Carson Peak Unit 1 well suggest that initial uplift along the Henrys Fork Fault occurred in the late early or early middle Eocene with the most active periods of uplift in the middle and late Eocene (Figure 8, Figure 24, Appendix 1). The approximate post-Paleocene throw of the Henrys Fork fault at Phil Pico Mountain is 2070 m (6800 ft). The Carson Peak Unit 1 well also reveals that just north of the Henrys Fork fault at Phil Pico Mountain the Bridger Formation (middle to late Eocene) is 520 m (1710 ft) thick; an additional 460 m (1500 ft) of Bridger Formation lies above the well on Phil Pico Mountain. Beneath the Bridger Formation are 400 m (1180 ft) of Green River Formation (early to middle Eocene), 1520 m (5010 ft) of Wasatch Formation (early Eocene), and 850 m (2800 ft) of the Fort Union Formation (Paleocene). Stratigraphic data from three sections located east to west across the Phil Pico Mountain quadrangle show that the Protero-zoic Red Pine Shale has substantially more sandstone and less shale in the eastern section of the quadrangle. Field observations suggest that the Red Pine Shale undergoes a facies change across the quadrangle. However, due to the lack of continuous stratigraphic exposures, the cause of this change is not known.
