This paper presents new interpretations of two normal-slip, low-angle faults near Smithfield and Richmond, Utah. The faults have previously been interpreted as landslides, gravity slides, slide blocks, and depositional contacts. Recent work in the Basin and Range province allows new interpretations concerning the origins of the low­-angle faults. Working hypotheses used to interpret origins of the faults are classified as folded thrust fault, rotated high-angle normal fault, gravity slide, listric normal fault, and low-­angle normal fault Among these general categories are several subhypotheses. The evaluation of each hypothesis includes a description of the geologic requirements of the hypothesis, a comparison of field data to the requirements, and a conclusion regarding the hypothesis. Field maps, computer analyses of fault orientations, geophysical surveys, well logs, and published discussions of low-angle-fault origins provide the data base from which to derive conclusions. The data best fit a low-angle-normal-fault hypothesis which states that low-angle normal faults in the study area represent a pre-Basin and Range style of extensional tectonism in which principal stress axes were in a transitional state between compressional tectonism and modern Basin and Range extensional tectonism. The northern low-angle normal fault formed as early as the late Eocene, followed by the southern low-angle normal fault in the early to middle Miocene(?). Episodes of high­-angle normal faulting followed formation of the southern low-angle normal fault. The faulting history indicates that two distinct stress states existed resulting in two different styles of normal faults. Schematic cross-sectional reconstructions based on two other low-angle-normal­fault subhypotheses and the gravity-slide subhypothesis 2 indicated that these subhypotheses could be valid However, the two low-angle-normal-fault subhypotheses cannot account for transitional stress states, and the gravity-slide subhypothesis explains only the southern low-angle normal fault. On the basis of geologic simplicity, the best hypothesis should explain both low-angle faults because of their similarities in deformation, orientation, and age. The applicability of the low-angle-normal-fault model to the rest of the Basin and Range province is somewhat limited. Too many local variables are involved to allow one model to be regionally applied. (112 pages)

<p>This study was planned as a combination of detailed field mapping, thin section petrography, whole rock geochemistry and amphibole chemistry of the rocks of the Port Coldwell intrusion. It was hoped that the results of the detailed field mapping would give a clearer picture of the stratigraphy and structure of the intrusion. It was hoped to define the mineralogy and textures of the various phases of the Port Coldwell intrusion enabling a postulation of possible physical conditions under which crystallization occurred. Through whole rock chemical analysis it was hoped to correlate the petrochemistry with the stratigraphy, and so to provide a chemical explanation of the differentiation process. Furthermore, it was hoped to classify the gabbros and through differentiation trends provided by the plots of the analyses, to determine whether the gabbro could be a feasible parent of the other phases of the intrusionThe amphibole found in each phase of the intrusion was to be determined in order to discover elemental trends and to provide corroborating evidence of a differentiation sequence suggested by other sources. </P> / Thesis / Master of Science (MSc)

Augmented reality (AR) systems are often used to superimpose virtual objects or information on a scene to improve situational awareness. Delays in the display system or inaccurate registration of objects destroy the sense of immersion a user experiences when using AR systems. AC electromagnetic trackers are ideally for these applications when combined with head orientation prediction to compensate for display system delays. Unfortunately, these trackers do not perform well in environments that contain conductive or ferrous materials due to magnetic field distortion without expensive calibration techniques. In our work we focus on both the prediction and distortion compensation aspects of this application, developing a “small footprint” predictive filter for display lag compensation and a simplified calibration system for AC magnetic trackers. In the first phase of our study we presented a novel method of tracking angular head velocity from quaternion orientation using an Extended Kalman Filter in both single model (DQEKF) and multiple model (MMDQ) implementations. In the second phase of our work we have developed a new method of mapping the magnetic field generated by the tracker without high precision measurement equipment. This method uses simple fixtures with multiple sensors in a rigid geometry to collect magnetic field data in the tracking volume. We have developed a new algorithm to process the collected data and generate a map of the magnetic field distortion that can be used to compensation distorted measurement data.

Le développement de nouveaux matériaux supraconducteurs et la mise au point de processus de fabrication de câbles comme les films YBaCuO, permettent d'envisager de nouvelles application ou d'en améliorer les performances. Pour l'étude des applications industrielles, il est nécessaire de connaitre les caractéristiques électromagnétiques de ces nouveaux matériaux. Pour tous les supraconducteurs, la difficulté réside dans la reconstitution de la loi électrique locale E(J), à partir des mesures. Cette thèse consiste donc à la mise au point d'outils théoriques et expérimentaux permettant la caractérisation des matériaux supraconducteurs à haute température critique. Les travaux ont principalement été menés sur deux méthodes : - la méthode MB, qui consiste à effectuer des mesures sur une bobine puis d'extraire les propriétés du ruban supraconducteur. - le field mapping, qui repose sur la mesure d'une cartographie de l'induction magnétique. Ces méthodes ont été testée et validée tant au niveau expérimental que théorique / The development of new superconducting materials and of new cables manufacturing processes such as YBaCuO films, allow to consider new application or to improve their performances. For the study of industrial applications, it is necessary to know the electromagnetic characteristics of these new materials. For superconductors, the difficulty lies in the reconstruction of the local electric law E(J), from measurements. This thesis therefore consists in the developing theoretical and experimental tools for characterization of high temperature superconductors. The work has mainly been carried out on two methods: - the MB method, which consists in making measurements on a coil and then extracting the properties of the superconducting tape. - the field mapping, based on the measurement of a map of the magnetic flux density. These methods have been tested and validated both experimentally and theoretically

Cette thèse s'inscrit dans le projet FUI-2011 BELOCOPA (Bouée Éjectable pour la LOcalisation et la COllecte des Paramètres de vol d'un Aéronef abîmé en mer). Il s'agissait de concevoir et de développer un équipement embarqué, extractible et autonome pour localiser rapidement et avec précision un aéronef abîmé en mer et récupérer par liaisons radio les principales données de vol à partir d'un patrouilleur maritime. Le but de cette thèse, au sein de l'Institut Fresnel, concernait l'étude et la réalisation de l'antenne principale de la balise. Cette antenne devait être très flexible et de petites dimensions pour être pliée et insérée dans un espace réduit de la balise et résistante lors son déploiement après son éjection de l'avion. La première partie du travail a eu pour objectif de caractériser en terme de permittivité les différents matériaux diélectriques entrant dans la constitution de la balise, à savoir les substrats sur lesquels sont fixées les antennes et le radôme. La deuxième partie de la thèse porte sur la conception d'antennes multi-bandes fonctionnant en modes dipolaires sur le plan de fréquences du cahier des charges du projet. Ces antennes ont la particularité d'être extrêmement souples. Cette souplesse a été obtenue en réalisant des motifs métalliques rayonnants sur une toile polyamide. Plusieurs motifs ont été étudiés et testés pour converger vers une antenne méandre fonctionnant à trois fréquences distinctes. A l'issue de cette étude, un prototype de l'antenne finale positionnée dans son radôme constitue le dernier maillon du prototype de la balise de détresse du projet BELOCOPA. / This thesis is part of the BELOCOPA project FUI-2011 (BELOCOPA means Ejected Buoy to LOcalize and COllect the data of a crashed plane in sea). It was about designing and developing an on-board, removable and autonomous, equipment to localize quickly and precisely an aircraft crashed in the sea, and to collect by telecommunication the main flight data from a patrol boat. The aim of this thesis, in the Fresnel Institute, was the study and the realization of the main antenna of the beacon. This antenna had to be very flexible with small dimensions to be folded and integrated in a reduced space of the beacon, and had to be strong during its deployment after the ejection of the plane. The aim of the first part of the work was to characterize in term of permittivity the different dielectric materials included in the composition of the beacon, namely the substrates of the antennas and the radome. The second part of the thesis was on the design of multi-band antennas working in dipolar modes on the frequency plan of the specification of the project. The characteristic of these antennas is to be very flexible. This flexibility was obtained realizing metal radiating pattern on a polyamide material. Several patterns have been studied and tested to get the final antenna with meander working at three different resonance frequencies. Following this study, a prototype of the final antenna integrated in the radome is the last link of the prototype of the distress beacon BELOCOPA.

The purpose of this work is the design of a gaussmeter with a three-axis probe for magnetic field mapping and subsequent reconstruction of the image using magnetic impedance tomography. Commercially available gaussmeters have low bandwidth for these purposes, and signals cannot be measured in synchronous detection mode. The aim of the thesis is select the most suitable magnetic field sensors for the MIT purposes and to design the entire measuring device to meet the measurement requirements in the wider frequency band and synchronous detection. Attention will also be paid to designing a suitable mechanical design of the probe and the location of the sensors. The proposed device will be tested and evaluated for MIT purposes.

The aim of this master´s thesis is to work out a comparison and evaluation of selected methods used for sound field mapping. Thesis will include software tools and results of sample measurement on test object for each mapping method.

This study examines landscape change in the Province of Jämtland during c. 1000–1750 AD. Settlement and arable cultivation are two of the most important sources in this study. They are therefore treated in depth, particularly farmsteads that were deserted during the late medieval agrarian crisis, so-called ödesbölen, and their fossil field-traces. The dissertation contains four major investigations. In the first investigation 610 possible ödesbölen were identified. The desertion was estimated at 50 per cent. The second investigation had its focus on the geographic location, and the conclusion was that the ödesbölen may have been deserted when the climate turned colder in the 14th century. The third investigation concerned medieval agriculture. Using historical maps and detailed mapping of fossil field traces it was established that the annually cultivated acreage decreased from the High Middle Ages until early modern times. This probably means that the agrarian crisis caused a change in the agrarian regime, from predominant arable farming to predominant stock-raising. The fourth investigation was whether the ownership or the use of the ödesbölen created obstacles to recolonization when the crisis subsided. This turned out not to be so in the case of ownership, but may have been so with regard to communal forest grazing. According to historical maps the ödesbölen in Jämtland were finally recolonized about 200 years later than for example in southern Sweden. The reasons probably were wars and a worse climate. The dissertation is capped off with both a model and a description of landscape change in Jämtland. Characteristic for the development of the landscape has been fluctuations in settlement. The ödesbölen are part of a pattern in which they are colonized, deserted, recolonized and again deserted in a cyclical course of events. The openness of the landscape is not part of this course of events.

Manipulating light by controlling surface plasmons on metals is being discussed as a means for bridging the size gap between micrometer-sized photonic circuits and nanometer-sized integrated electronics. Plasmonic waveguides based on metal nanoparticles are of particular interest for circumventing the diffraction limit, thereby enabling high-speed communication over short-range distances in miniaturized micro-components. However, scalable, inexpensive fine-tuning of particle assemblies remains a challenge and near-field probing is required to reveal plasmonic interactions. In this thesis, self-assembled waveguides should be produced on DNA scaffolds. DNA origami is an extremely versatile and robust self-assembly method which allows scalable production of nanostructures with a fine control of assemblies at the nanoscale. To form the plasmonic waveguides, six-helix bundle DNA origami nanotubes are used as templates for attachment of highly monodisperse and monocrystalline gold nanoparticles with an inter-particle distance of 1-2 nm. In the first part of this thesis, the effects of parameters which are involved in assembly reactions are systematically investigated. The assembly yield and binding occupancy of the gold nanoparticles are determined by an automated, high-throughput image analysis of electron micrographs of the formed complexes. As a result, unprecedented binding site occupancy and assembly yield are achieved with the optimized synthesis protocol. In addition, waveguides with different sizes of gold nanoparticles and different inter-particle distances, quantum dots attachments to the waveguides and multimerization of the waveguides are successfully realized. In the second part of this thesis, direct observation of energy transport through a self-assembled waveguide towards a fluorescent nanodiamond is demonstrated. High-resolution, near-field mapping of the waveguides are studied by electron energy loss spectroscopy and cathodoluminescence imaging spectroscopy. The experimental and simulation results reveal that energy propagation through the waveguides is enabled by coupled surface plasmon modes. These surface plasmon modes are probed at high spatial and spectral resolutions. The scalable self-assembly approach presented here will enable the construction of complex, sub diffraction plasmonic devices for applications in high-speed optical data transmission, quantum information technology, and sensing. / Die Manipulation des Lichts durch die Kontrolle von Oberflächenplasmonen auf metallischen Oberflächen und Nanopartikeln gilt als vielversprechende Methode zur Überbrückung der Größen-Lücke zwischen Mikrometer-großen photonischen und nanometer-großen elektronischen Schaltkreisen.

Im ersten Abschnitt dieser Arbeit werden die beeinflussenden Faktoren dieser Assemblierungsreaktion systematisch untersucht. Die Ausbeute der assemblierten Strukturen und die Besetzung der Bindungsstellen werden durch eine automatisierte und effiziente Bildanalyse von Elektronenmikroskopieaufnahmen ausgewertet. Durch die Entwicklung eines optimierten Syntheseprotokolls werden bisher unerreichte Assemblierungsausbeuten ermöglicht. Zusätzlich erfolgen die experimentelle Realisierung von Strukturen mit verschieden großen Goldnanopartikeln und unterschiedlichen interpartikulären Abständen, sowie die Anbindung von Quantenpunkten an die Wellenleiter und eine Verknüpfung der assemblierten Strukturen. Der zweite Abschnitt dieser Dissertation befasst sich mit der Untersuchung des Energietransports in selbstassemblierten Wellenleitern über einen fluoreszierenden Nanodiamanten. Dazu erfolgen hochaufgelöste Nahfeldmessungen der Wellenleiter mittels Elektronenenergieverlustspektroskopie und Kathodolumineszenz-mikroskopie. Die experimentellen Ergebnisse und zusätzlich durchgeführte Simulationen bestätigen eine durch gekoppelte Oberflächenplasmonenmoden induzierte Weitergabe der Energie innerhalb des Wellenleiters. Diese Oberflächenplasmonenmoden werden bei hoher räumlicher und spektraler Auflösung untersucht. Das hier umgesetzte Konzept der Selbstassemblierung wird den Aufbau komplexer plasmonischer Geräte für Anwendungen im Bereich der optischen Hochgeschwindigkeitsdatenübertragung, der Quanteninformations-technolgie und der Sensorik ermöglichen.
