Abstract:
Laboratory fire tests were performed in still air, for variable inclinations (10°, 15°) and fuel bed dimensions (1.28×2.50–3.0×4.6m2), with homogeneous fuel beds of pine needles and pine wood excelsior. The fire ignition was made at a point, along a closed line with no fuel inside and along a straight edge of the fuel bed. The tests were recorded with an infrared camera and various techniques were developed to implement direct and indirect empirical methods of construction of the ‘orientation function’ of the fire in the given fuel bed and ambient conditions, showing how the rate of spread of a steady straight fire front depends on its orientation on the terrain. The direct method uses a set of straight fire fronts with various orientations whereas the indirect method uses essentially a point ignited fire front. Contrary to what is assumed in BehavePlus model, the orientation function is observed to depend significantly on the properties of the fuel bed. In all tests with closed fire fronts, the full steadiness required by the indirect method was not achieved (namely, at the head of the front), although, for slope angle of 10°, the corresponding errors induced on the orientation function were small.

Abstract:
This paper describes experiments in which high purity copper single crystals of two different orientations were processed for one pass by equal-channel angular pressing (ECAP) and the deformed structures were examined using optical microscopy (OM), orientation imaging microscopy (OIM) and transmission electron microscopy (TEM). The first single crystal (0° specimen) was oriented within the entrance channel of the die so that the {111} slip plane and the <110> slip direction were parallel to the theoretical shear plane and shear direction, respectively. The second crystal (20° specimen) was oriented with the {111} slip plane and the <110> slip direction rotated by 20° in a clockwise sense from the theoretical shear plane and shear direction, respectively. For the 0° specimen, after passing through the shear plane there were two crystallographic orientations representing the initial orientation and an orientation rotated by 60° in a counter-clockwise sense from the initial orientation. For the 20° specimen, there was an orientation rotated by 20° in a counter-clockwise sense from the initial orientation after passing through the shear plane.

Abstract:
Curvilinearity is a perceptual feature that robustly predicts preference ratings for a variety of visual stimuli. The predictive effect of curved/angular shape overlaps, to a large degree, with regularities in second-order edge-orientation entropy, which captures how independent edge orientations are distributed across an image. For some complex line patterns, edge-orientation entropy is actually a better predictor for what human observers like than curved/angular shape. The present work was designed to disentangle the role of the two features in artificial patterns that consisted of either curved or angular line elements. We systematically varied these patterns across two more dimensions, edge-orientation entropy and the number of lines. Eighty-three participants rated the stimuli along three aesthetic dimensions ( pleasing, harmonious, and complex). Results showed that curved/angular shape was a stronger predictor for ratings of pleasing and harmonious if the stimuli consisted of a few lines that were clearly discernible. By contrast, edge-orientation entropy was a stronger predictor for the ratings if the stimuli showed many lines, which merged into a texture. No such differences were obtained for complexity ratings. Our findings are in line with results from neurophysiological studies that the processing of shape and texture, respectively, is mediated by different cortical mechanisms.

Abstract:
For three-component laser velocimeter systems, the change in projected area of the coincident measurement volume for different flow directions will introduce an “angular” bias in naturally sampled data. In this study, the effect of turbulence level and orientation of the measurement volumes on angular bias errors was examined. The operation of a typical three-component laser velocimeter was simulated using a Monte Carlo technique. Results for the specific configuration examined show that for turbulence levels less than 10 percent no significant bias errors in the mean velocities will occur and errors in the root-mean-square (r.m.s.) velocities will be less than 3 percent for all orientations. For turbulence levels less than 30 percent, component mean velocity bias errors less than 5 percent of the mean velocity vector magnitude can be attained with proper orientation of the measurement volume; however, the r.m.s. velocities may be in error as much as 10 percent. For turbulence levels above 50 percent, there is no orientation which will yield accurate estimates of all three mean velocities; component mean velocity errors as large as 15 percent of the mean velocity vector magnitude may be encountered.

Abstract:
A pure iron tape with cube orientation was fabricated by cold rolling and annealing. The orientation characteristics of the pure iron tape were evaluated using electron back-scattering diffraction (EBSD) analysis. The secondary recrystallized grains with cube orientation was formed on the tape surface for the pure iron tape. The coarse grains with a grain size of ca. 1mm were observed on the tape surface. The areal fraction of cube orientations with an angular deviation ≤ 20 ̊ amounts to ca. 81%.

Abstract:

A slender body theory method developed for a body moving parallel to a wall in shallow water is extended to include angular orientation of the body to the wall. The method satisfies only the zero normal velocity condition on the external boundaries but does not take into account the effect of induced flows on the body itself. A spheroid and a Series 60, block .80 hull were the bodies studied. The side force and yaw moment on each body were determined numerically for varying angular orientation with respect to either a single wall or canal bank. For both cases results for a range of depths and wall separation distances are presented. It is found that the method gives good qualitative side force predictions for a body moving parallel to a wall, but is unable to correctly predict the yaw moment or the side force due to angular orientation. This result dictates the need for a more complex mathematical model to properly represent the flow than the simple model and quasiâ steady method used here.

Full text
Abstract:
Using three linear accelerometers and three angular rate sensors arranged to measure local acceleration in the X, Y, and Z directions and angular velocity about those axes, it is possible to calculate spatial orientation and position in a global coordinate system. The intent of this thesis is to use this calculation to provide the head trajectory of an Anthropomorphic Test Device (ATD) to supplement or replace photometric analysis. This thesis examines the various parameters of the calculations of the spatial orientation and position to determine the most accurate and efficient method. Using the local angular velocity as an input, this method determines spatial orientation as a function of a unit quaternion by numerically solving a system of ordinary differential equation. The parameters of the numerical integration examined are the numerical integration methods, time step, and order of rotation. These functions are examined through simulation data generated by various MADYMO models. The MADYMO three-dimensional multi-body simulations output the linear accelerations and angular velocity of selected bodies in simulations similar to the data provided from accelerometers and angular rate sensors during dynamic impact testing. Simulation data is useful in the examination and validation of the different parameters used in the method due to the lack of noise and gravitational effects incurred during physical dynamic impact testing. The method is evaluated for dynamic impact testing through a comparison between the calculated spatial orientation and position using the algorithm and photometric analysis as well as physical limitations in the test setup, i.e. rigid bulkhead. The method is demonstrated to be successfully implemented into the NIAR Crash Dynamics Laboratory at Wichita State University.

Abstract:
Flight control of small spacecraft is one of the most time-consuming and complex components of the process of their operation. This is especially true for small spacecraft, designed to implement modern space programs. As follows from the existing experience of creation and operation of small spacecraft, the reliability and safety of their flight are determined not only by the perfection of the aircraft, but also the quality of methods, tools and flight control systems. In addition, the requirements for control systems affect the appearance and characteristics of the small spacecraft , its systems and onboard software.

Abstract:
Diffusion-weighted magnetic resonance imaging (MRI) has allowed unprecedented non-invasive mapping of brain neural connectivity in vivo by means of fiber tractography applications. Fiber tractography has emerged as a useful tool for mapping brain white matter connectivity prior to surgery or in an intraoperative setting. The advent of high angular resolution diffusion-weighted imaging (HARDI) techniques in MRI for fiber tractography has allowed mapping of fiber tracts in areas of complex white matter fiber crossings. Raw HARDI images, as a result of elevated diffusion-weighting, suffer from depressed signal-to-noise ratio (SNR) levels. The accuracy of fiber tractography is dependent on the performance of the various methods extracting dominant fiber orientations from the HARDI-measured noisy diffusivity profiles. These methods will be sensitive to and directly affected by the noise. In the first part of the thesis this issue is addressed by applying an objective and adaptive smoothing to the noisy HARDI data via generalized cross-validation (GCV) by means of the smoothing splines on the sphere method for estimating the smooth diffusivity profiles in three dimensional diffusion space. Subsequently, fiber orientation distribution functions (ODFs) that reveal dominant fiber orientations in fiber crossings are then reconstructed from the smoothed diffusivity profiles using the Funk-Radon transform. Previous ODF smoothing techniques have been subjective and non-adaptive to data SNR. The GCV-smoothed ODFs from our method are accurate and are smoothed without external intervention facilitating more precise fiber tractography. Diffusion-weighted MRI studies in amyotrophic lateral sclerosis (ALS) have revealed significant changes in diffusion parameters in ALS patient brains. With the need for early detection of possibly discrete upper motor neuron (UMN) degeneration signs in patients with early ALS, a HARDI study is applied in order to investigate diffusion-sensitive changes reflected in the diffusion tensor imaging (DTI) measures axial and radial diffusivity as well as the more commonly used measures fractional anisotropy (FA) and mean diffusivity (MD). The hypothesis is that there would be added utility in considering axial and radial diffusivities which directly reflect changes in the diffusion tensors in addition to FA and MD to aid in revealing neurodegenerative changes in ALS. In addition, applying adaptive smoothing via GCV to the HARDI data further facilitates the application of fiber tractography by automatically eliminating spurious noisy peaks in reconstructed ODFs that would mislead fiber tracking.

Introdução: O Complexo articular do ombro é propício a várias patologias e disfunções do movimento que parecem estar relacionadas às alterações na orientação da omoplata. A literatura recentemente publicada enfatiza a necessidade de desenvolvimento de ferramentas clínicas medição da orientação da omoplata que sejam precisas e de fácil utilização. Objetivo: Contribuir para o desenvolvimento de um método clínico para medir a orientação da omoplata a 0º e 90º de elevação do ombro. Metodologia: Foi feito um estudo correlacional utilizando uma amostra de 20 participantes assintomáticos, selecionados por conveniência do corpo discente da ESS-IPS. Foram coletadas cinco medições lineares (M1, M2, M3, M4 e M5) por dois avaliadores independentemente em dois momentos diferentes entre as referências ósseas da coluna vertebral e da omoplata na elevação do braço a 0º e 90º no plano sagital, coronal e escapular. Foi coletada simultaneamente a orientação 3D da omoplata utilizando um dispositivo de varrimento eletromagnético (Flock of Birds) e o movimento reconstruído de acordo com as recomendações da Sociedade Internacional de Biomecânica. Resultados e Discussão: O valor das correlações entre medidas lineares e angulares da posição e orientação da omoplata foram definitos como de aceitáveis e moderados, sempre acima de 0,4 e 0,5, respectivamente. Com a elevação do MS a 0º no plano frontal, foram encontradas correlações estatisticamente significativas entre a rotação interna da omoplata com M2 e M5, e entre a rotação inferior da omoplata com M1, M3 e M4. No plano sagital, foram observadas correlações significativas entre a rotação interna da omoplata com M4, e da rotação superior da omoplata com M1 e M4. No plano da omoplata, encontraram-se correlações estatisticamente significantes entre a rotação interna da omoplata e M2 e da rotação inferior com M1. Na posição de 90º de elevação do MS, apenas M2 correlacionou-se significativamente com a rotação interna da omoplata. Conclusão: Estes resultados preliminares revelam uma promessa de um método clínico preciso e fácil de usar para quantificar a orientação da omoplata com base em medições lineares.
Abstract: Introduction: The shoulder complex, is prone to several pathologies and movement dysfunctions that seem to be related to alterations in scapula orientation. Recent published literature emphasize the need for the development of accurate and easy to use clinical tools to measure scapula orientation. Objective: Contribute to the development of a clinical method to measure scapula orientation at 0º and 90º of shoulder elevation. Methodology: A correlational study was conducted with a sample of 20 asymptomatic subjects, selected by convenience from the student community of the ESS-IPS. Five linear measurements (M1, M2, M3, M4 and M5) were independently collected separately by 2 researchers and in 2 different moments between pre-defined bony landmarks of the vertebral column and scapula with the arm at 0º and 90º of shoulder elevation in the sagittal, coronal and scapula’s plane. Simultaneously, scapular 3D orientation was collected using an electromagnetic tracking device (Flock of Birds) and motion reconstructed according to the International Society of Biomechanics recommendations. Results and Discussion: Correlations values between linear and angular measurements of the scapular orientation, were set as acceptable and moderate whenever above a cut-point of 0.4 and 0.5, respectively. With the arm at 0º of elevation, in the coronal plane, it were found statistical significant correlations between the scapula internal rotation values and M2 and M5, and between scapula’s medial rotation and M1, M3 and M4. In the sagittal plane, it were observed statistical significant correlations between scapula’s internal rotation and M4, and the scapula’s lateral rotation, and M1 and M4. In the scapula plane, statistical significant correlations were found between the scapula’s internal rotation and M2, and scapula’s medial rotation and M1. At 90º of arm elevation, only M2 was found to be statistical significant correlated with scapula’s internal rotation. Conclusion: This preliminary results unveil a promise application of an easy to use and accurate clinical method to quantify scapula orientation based on linear measurements.

Abstract:
Cette thèse traite du contrôle et de la caractérisation de l'alignement et de l'orientation du point de vue théorique et expérimental. L'alignement d'une molécule linéaire consiste à obtenir une probabilité élevée de localisation de l'axe internucléaire symétrique autour de l'axe de polarisation du champ tandis que l'orientation privilégie un sens particulier le long du champ. L'orientation à l'aide d'impulsions bi couleur (2+1) non résonnantes est étudiée en détail et les conditions permettant d'obtenir une orientation efficace sont examinées. Un schéma bi couleur où la deuxième harmonique est en quasi-résonance avec un niveau vibrationnel de la molécule est également étudié. Cette technique présente l'avantage d'offrir un paramètre supplémentaire à savoir l'écart à la résonance qui peut être ajusté de manière à optimiser l'orientation moléculaire. Finalement une nouvelle technique expérimentale de détection de l'alignement moléculaire est présentée. Celle-ci permet une détection monocoup de l'alignement moléculaire sur une étendue temporelle jusqu'alors inégalée.

Abstract:
De nos jours, les matériaux composites sont très largement utilisés dans l’industrie aéronautique et aérospatiale car ils ont de très bonnes tenues mécaniques, mais ces matériaux comportent de fortes hétérogénéités dues aux fibres et aux liants qui les constituent. Ainsi, depuis de nombreuses années, l’équipe TIFC «Thermal Imaging Fields and Characterization » du département TREFLE de l’institut I2M développe des méthodes de mesure des propriétés thermophysiques de matériaux hétérogènes dans le plan ou dans l’épaisseur. Ces méthodes sont très variées du point de vue des méthodes inverses (transformée intégrale, double décomposition en valeurs singulières, …) ou expérimentale (Flash, diode laser, …). Le faible coût des diodes lasers et des systèmes de déplacement de miroirs galvanométriques ont permis de développer un système complet de scanner optique laser, monté sur un banc de mesure. Il permet de revisiter les différents types de sollicitations thermiques et de réaliser une infinité de combinaisons spatiotemporelles d’excitations thermiques par méthode laser. Ceci est une des principales originalités de ce travail. De nouvelles méthodes inverses basées sur la réponse thermique au point source impulsionnel et sur la séparabilité des champs de température ont été proposées. Ces méthodes ont permis d’estimer le tenseur de diffusivité thermique selon les axes principaux d’anisotropie, mais aussi hors des axes du repère de l’image, où il est possible de déterminer l’orientation des axes d’anisotropie, lorsque le transfert de chaleur s’effectue hors des axes du repère de l’image. Ces méthodes ont permis d’obtenir des résultats intéressants comptetenu de leur simplicité. De plus, elles ont permis d’obtenir des cartographies de diffusivités thermiques dans le plan car, comparées aux autres méthodes, elles permettent d’obtenir des estimations du tenseur de diffusivité thermique localement grâce à l’obtention d’une cartographie de flux thermique surfacique via le scanner optique laser
Nowadays, composite materials are widely used in the aeronautic and aerospace industries because of their high mechanical resistance. However, they have a large heterogeneity due to the fiber and matrix they are made of. In this way, for many years, the TIC team «Thermal Imaging Fields and Characterization » from TREFLE department of I2M laboratory develops methods to measure thermal in-plane properties of heterogeneous materials such as inverses (integral transforms, double singular value decomposition…) or experimental (Flash, laser diode…) methods. The recent progress made in optical control, lasers and infrared (IR) cameras enables the development of a new scanning system (based on galvanometer-mirror) which allows the easy control of a laser hot spot spatial and temporal displacements over a plane surface. The low cost of laser diodes and optical control (galvanometric mirror) systems allows to develop a laser scanning system fixed on a test bench. We can revisit the different types of thermal excitation and realize infinite spatio-temporal combinations of thermal excitations by laser method. This is one of this thesis aims. New inverse methods based on the thermal response to an instantaneous point source heating, and temperature fields separability, have been proposed. These methods allow to estimate the thermal diffusivity tensor along the main axes of anisotropy, but also out of those axes, where it is possible to estimate the anisotropy axes orientation when the heat transfer takes place out of the image axes. These methods have produced interesting results in view of their simplicity. Moreover, they made it possible to obtain in-plane thermal diffusivities maps because, compared to the other methods, they allow to obtain, locally, thermal diffusivity tensor estimations by getting a surface heat flux map using the laser optical scanner

Abstract:
The variation of the incidence angle over the year is an important parameter determined the performance of the module. The standard orientation of the module or a PV system, the perpendicular positioning of the sun to the module’s surface occurs twice a year. In outdoor exposed, angular losses of the module decrease the output of the PV or the system of PV. Although these losses are not always negligible, they are commonly not taken into account when correcting the electrical characteristics of the PV module or estimating the energy production of PV systems. This chapter is focused on the measurement of the angular response and spectral radiation (global and direct radiation) of solar cells based on two different silicon technologies, monocrystalline textured (m-Si) and non textured (mc-Si). The analysis of the source of deviation from the theoretical response, especially those due to the surface reflectance. As main contributions, the effects of glass encapsulation on the angular response of the modules are investigated by comparing the electrical parameter of the textured module to no textured and quantify electrical angular losses in this measurement area.

Abstract:
Recently, it has been discovered that RF waveguides can be used as onboard wireless sensors for the direct measurements of angular positions of a moving object and that a combination of RF waveguides may be used to measure full spatial angular orientation of the object. This paper deals with the computational issues that arise in resolving the spatial orientation from the measurement data of a set of RF waveguide sensors. The paper presents an algorithm that combines a heuristic search method with the least-squares approach for computing the full orientation of an object. The goal is to develop a general and efficient method for computing spatial orientation from the sensor data of a class of angular position sensors that have smooth sensor profiles.

Abstract:
CINEMA (CubeSat for Ions, Neutrals, Electrons and MAgneticfields) will image energetic neutral atoms (ENAs) in the magnetosphere, and make measurements of electrons, ions, and magnetic fields at high latitudes. To satisfy the mission requirements, the three unit cubesat was designed. The spin axis needs to be in the ecliptic normal and the spin rate needs to be 4 rpm. The only power source for CINEMA is the solar panels. External torques are generated by an orthogonal pair of coils acting with the earths magnetic field. This paper provides the control strategy, given the limited power and available sensors, to optimize the convergence of the spin and attitude control.
