Nonlinear surface approximation using photogammetryOsgood, Elizabeth 12 April 2006 (has links)
Many satellite applications require a model that represents a surface as it deforms
over time. Yet, space applications demand a precise, low-weight, low-volume, and easy
to implement solution. A metrology sensing system is presented in this thesis, consisting
of a series of cameras and laser dot projectors positioned along the length of the antenna.
This system accurately models the geometry of the surface to meet the demands of a
space based radar. Each laser dot projector casts a matrix of points onto the antenna
surface. The points are then imaged simultaneously by a pair of cameras, each having a
different, but overlapping, viewpoint. Given the two overlapping images, a Gaussian
nonlinear least squares algorithm solves the stereo-triangulation problem which provides
the coordinates of the projected points and thereby maps the surface.
There are three different strategies discussed in this thesis. The first strategy
assumes the positions and orientations of the cameras are absolutely known. This
produces an extremely accurate result; yet it is unrealistic to assume absolute knowledge
of cameras locations and orientations for the application. The next strategy assumes the
positions and orientations of the cameras are completely unknown in addition to the
unknown surface. This program produces a less accurate, but more realistic, result
considering the dynamic nature of rigid structures in space. To increase the accuracy and
improve the robustness of these results, the third method employs a global metrology
sensing system to reduce the uncertainty in the location and orientation of the outboard
cameras relative to the center camera. This approach estimates the surface extremely accurately and, although more complex, offers advantages and addresses the desire for a
family of designs wherein higher accuracy is achievable by further optimization.

Personality, Social Power, and AutonomyDi Domenico, Stefano 31 December 2010 (has links)
Autonomy is defined as the subjective experience of congruence between one’s basic values and behavior. Research guided by SDT has focused on the socializing conditions that either foster or undermine the individual’s autonomy at the expense of considering the individual’s capacity to function autonomously by actively and purposively shaping his or her social ecology. The present research adopted a social-ecological approach to the problem of human autonomy, wherein people are presumed to strive for autonomy by relying on their traits and abilities to extract what they need from the social environment. After completing a range of individual difference measures, first-year female undergraduates engaged in a leaderless group discussion task and provided round-robin ratings of their group-members’ social power; self-reported autonomy satisfaction was also assessed. Findings revealed that the personality trait Openness to Experience held predictive relations to social power attainment and, through this association, was positively related to autonomy satisfaction.

The determinants of audit fees : an analytical studyRamzy, Wafaa Abdel January 1988 (has links)
This study investigates the factors affecting the level of audit fees paid by companies to their auditors. Firstly, all the likely factors thought to be affecting the level of audit fees were identified through a literature survey. These factors were classified into three groups i.e., size, complexity, and others. The relative importance of these factors was determined empirically and statistically. The empirical study was undertaken by mailing two questionnaires to samples of 100 companies, and 100 audit firms. Preliminary interviews were carried out in order to identify if the most important factors collected through the literature should be considered suitable for further inclusion in the final questionnaire. The questionnaires were not used to collect data or to quantify the subjective factors. They were used to assess the degree to which the factors previously identified were important determinants of the audit fee, and whether other determinants should also be considered. The data for the statistical analysis was obtained from published data i.e., Data Stream, Companies' Annual Reports, and Who Owns Whom. In carrying out the statistical analysis, Multiple Regression arid Principal Component Techniques were used to assess the magnitude of the association between the size and complexity factors and audit fees. An audit fee regression model was developed which explains 90Y. of the variation in audit fees of the largest 65 manufacturing companies in the U.K. on the basis of their size and complexity. The results of both the empirical study, and the statistical analysis revealed that the company size (in terms of debtors, stocks work in progress, turnover, creditors, and total employment costs), and its complexity (in terms of number of subsidiaries, and number of countries in which the company operates) are the major objective determinants of audit fees. The empirical study also revealed that the quality of the company's internal control system, competition in the audit market, and the risk involved in the audit work are the major subjective determinants of audit fees. In addition, the statistical analysis revealed that the factors debtors, number of subsidiaries, and total employment costs are the most significant predictors of audit fees, and the audit fee model which involves these three factors explains 92Y. of the variation in audit fees.

A critical evaluation of age determination of ringed seals (Phoca hispida Schreber 1775) /Albright, Don January 1990 (has links)
Precision of determining age in ringed seals (Phoca hispida) was examined by repeated readings of undecalcified cross sections and decalcified stained longitudinal sections of mandibular canines. There appeared to be geographical differences in repeatability although this could not be tested statistically. There was no difference in repeatability between cross and stained sections. / The effect of precision on population parameters was examined. Smoothing procedures necessary to construct life tables and to do Leslie matrix calculations obscured any differences in ages between readings. Variance between readings was found to give inconsistent notions of sexual maturity. Imprecision caused little overall difference in growth curves. / Without known age animals, accuracy cannot be evaluated directly. High correlation between ages from canines from different sides of the same animal, between dentine and cementum of teeth from the same animal, and between readers examining the same sets of teeth gave an indirect suggestion of accuracy.
