ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / This paper presents a practical implementation of a hardware design for transmission of data over aircraft power lines. The intent of such hardware is to significantly reduce the wiring in the aircraft instrumentation system. The potential usages of this technology include pulse code modulation (PCM), Ethernet and other forms data communications. Details of the fieldprogrammable gate array (FPGA) and printed circuit board (PCB) designs of the digital and analog front end will be discussed. The power line is not designed for data transmission. It contains considerable noise, multipath effects, and time varying impedance. Spectral analysis data of an aircraft is presented to indicate the difficulty of the problem at hand. A robust modulation is required to overcome the harsh environment and to provide reliable transmission. Orthogonal frequency division multiplexing (OFDM) has been used in power line communication industry with a great deal of success. OFDM has been deemed the most appropriate technology for high-speed data transmission on aircraft power lines. Additionally, forward error correction (FEC) techniques are discussed.

The numerous illustrations--or better yet demonstrations--in Viollet-le-Duc's Dictionnaire Raisonne of Gothic architecture were the most powerful means of implementing biological metaphors in order to transfer or situate the discourse of architecture within the realm of nineteenth century positivistic science. Viollet-le-Duc borrowed dissective strategies of representation from the field of anatomy to implement his alternate 'vision' for appropriating architectural knowledge. By inscribing anatomical metaphors within his architectural drawings, Viollet-le-Duc could filter the viewer's conception of architecture through his own appropriation of anatomy's critical and selective methods of representation. This scientific approach to architectural drawing was in perfect harmony with Viollet-le-Duc's textual and conceptual mission in the Dictionnaire to not only demystify architectural knowledge as practiced at the Ecole des Beaux-Arts, but also to critically reconfigure the reader's relationship to it according to his own system. Through this process, it was his intent to change the public's way of thinking and seeing architecture.

La Saline d'Arc-et-Senans, construite à partir de 1774 selon les plans de l'architecteClaude Nicolas Ledoux, est aujourd'hui un centre touristique et culturel reconnu, notamment depuisson classement comme patrimoine mondial par l'Unesco en 1982. Mais son histoire est avant toutcelle d'un lieu de production du sel, qui fonctionne pendant plus d'un siècle. Sur décision de la Fermegénérale, elle est construite pour répondre aux difficultés rencontrées dans l'exploitation des sourcessalées à la Saline de Salins, en particulier le manque de bois. Saline sans ressources en sel, son exploitationpose la question de son manque d'autonomie, qui explique son échec économique. Inscrite dansl'ensemble juridico-économique que représentent les Salines de l'Est, elle peine à trouver sa place surle marché du sel. Les Salines de l'Est, d'abord protégées par le monopole d'État sur le sel jusqu'à la loide 1840, sont ensuite livrées à la concurrence des entrepreneurs privés, qui tentent de réunir au seind'une société anonyme l'ensemble des concessions et mines de sel de l'Est. La Saline d'Arc-et-Senans,bien moins rentable que les autres, sans possibilité d'amélioration technique, doit fermer ses portes en1895. Elle échappe alors de peu au destin habituel des anciens lieux de production, celui de la friche.Inscrite sur la liste des monuments historiques en 1926 et rachetée par le département du Doubs en1927, elle pose la question de l'avenir des sites industriels dont l'activité cesse. Sans préoccupationspatrimoniales particulières, plusieurs projets de reconversion se succèdent jusque dans les années 1960,sans qu'aucun d'entre eux aboutisse. C'est l'intervention des technocrates de la culture qui apporte lasolution en 1972, avec la création du Centre du futur. L'identité de ce lieu, qui a été progressivementvidé de sa mémoire industrielle, est reconstruite autour de la notion de cité idéale et la Saline devientle patrimoine de l'utopie. Cette nouvelle lecture des lieux, si elle en permet la sauvegarde, montreaujourd'hui ses limites pour l'exploitation touristique de la Saline, qui peine à armer une identité cohérente auprès du public. Ainsi, en occultant la mémoire industrielle du lieu, la Saline d'Arc-et-Senansest un exemple unique de patrimoine inventé. / The Saltworks of Arc-et-Senans were built from 1774 according to the drawings of thearchitect Claude Nicolas Ledoux. Today they are a famous touristic and cultural centre, especially since they have been inscribed on the Unesco World Heritage List in 1982. However their history is before everything a history of a place where salt is produced during more than one century. Further to the decision of the Ferme générale, they were built to solve the difficulties about salt sources exploitation at the saltworks of Salins, particularly the lack of wood. Because they are saltworks without salt resources, their exploitation question their lack of autonomy behind their economic failure. They struggle to find a place in the salt market because of legal and economic frameworks of the Salines de l'Est. These latter were firstly protected by the state monopoly on salt until the law of 1840. Then they were left incompetiton with private entrepreneurs who tried to gather all the eastern salt mines within a public limited company. The Saltworks of Arc-et-Senans closed in 1895 because they were less profitable than the others and this could not be improved. They narrowly escaped usual destiny of former production places : become an industrial wasteland. In 1926, they were listed historical monument then bought by the department of Doubs in 1927. It was the time to approach the future of industrial sites whose activity stopped. Many projects of conversion suceeded each other until the 1960s with no results. A solution was found in 1972 by technocrats working in cultural fields, with the creation of the Centre du futur. The identity of this place was rebuilt with the concept of ideal city and the Saltworks became the heritage of utopia. However from a touristic point of view, they struggle today to show a coherentidentity to visitors. Because the industrial memory of this place has been eclipsed, the Saltworks of Arc-et-Senans is an unique example of invented heritage.

Le milieu du XVIIIe siècle marque une césure dans l'histoire du Canada. Après deux siècles de présence française, le pays passe sous domination anglaise à l’issue de la guerre de Sept Ans qui entraîne la fin de la Nouvelle-France. Ce changement de domination génère des bouleversements structurels dans le paysage social du pays, touchant particulièrement les élites, dont la plupart étaient officiers militaires chargés du maintien de l'ordre et de la domination sur le territoire et représentants du pouvoir royal gérant les structures et l'encadrement politique. Souvent nobles, elles offraient un code de conduite et un modèle culturel indéniable. La perte de la position centrale qu’elles occupaient dans la société canadienne pose la question de leur adaptation sous le régime anglais, étudiée au travers de l’exemple de la famille Salaberry. Cette famille, affiliée à la noblesse, proche du prince anglais Édouard duc de Kent, compte dans ses rangs un héros d’une bataille durant la guerre de 1812-1815 et présente un profil atypique. Cette étude, menée à partir des documents personnels dont une importante correspondance et de nombreux documents notariés, permet d'entrer dans l'intimité d'une famille de la noblesse canadienne-française du tournant du XIXe siècle, d'en dégager les comportements familiaux et sociaux ainsi que leurs évolutions, mais aussi d'étudier l'adaptation politique et professionnelle par la participation au fonctionnement du nouveau régime et l'acculturation du point de vue linguistique mais aussi religieux des élites sous les premières décennies du régime anglais au Québec. / The mid-eighteenth century marked a break in Canada's history. After two centuries of French presence, the country came under British domination at the end of the Seven Years' War after New France’s defeat. This shift in dominance brought about structural upheavals in the country's social landscape, particularly affecting the elites, most of whom were military officers in charge of maintaining order and domination on the territory, and representatives of the royal power. Often of noble origin, they embodied a code of conduct and an undeniable cultural model. The loss of the central position they hold in Canadian society raised the question of their adaptation under the British regime, which is studied in this thesis through the example of the Salaberry family. This family presents an atypical profile: it was affiliated with the French nobility but was close to the English prince Edward Duke of Kent and it counted among its ranks a hero of a battle fought during the war of 1812-1815. This study, based on personal documents, including a large correspondence as well as many notarized documents, allows to critically examine the intimacy of a family of the Canadian nobility at the turn of the 19th century. In doing so it helps to identify and trace the development of family and social behaviors. This case study also allows for an analysis of the political and professional adaptation of French elites through the participation in the workings of the new regime and their linguistic and religious acculturation during the first decades of the British regime in the Quebec Province.

L'étude du dispositif vestimentaire à la cour de Bourgogne de 1430 à 1455 s'appuie sur l'analyse systématique et informatisée de la comptabilité des ducs de Bourgogne, et s'oriente vers cinq points : décrire la terminologie du costume et son discours écrit ; rapprocher, année par année, la production vestimentaire et les activités de la cour, en regard avec les récits des chroniqueurs ; comprendre l'organisation des approvisionnements basés sur les rapports humains (organigramme,vie du vêtement, tables des fournisseurs) ; analyser les rythmes et niveaux de consommation par personnes et/ou par groupes, avec notamment un point sur le droit de robe à cette période ; comprendre la personnalité vestimentaire de la cour de Bourgogne, avec en particulier une proposition d'explication de la permanence de la couleur noire chez le duc Philippe le Bon. La conclusion s'oriente notamment vers la notion d'évolution, idée centrale de cette étude de 25 ans de costumes dans une société restreinte.

This thesis describes the specification, design and implementation of a software-defined radio system on a two-channel 14-bit digitizer/generator. The multi-stage interpolations and decimations which are required to operate two analog-to-digital converters at 800 megasamples per second (MSps) and two digital-to-analog converters at 1600 MSps from a 25 MSps software-side interface, were designed and implemented. Quadrature processing was used throughout the system, and a combination of fine-tunable low-rate mixers and coarse high-rate mixers were implemented to allow frequency translation across the entire first Nyquist band of the converters. Various reconstruction filter designs for the transmitter side were investigated and a cheap implementation was done through the use of programmable base-band filters and polynomial approximation.
