Abstract:
Traditional methods of performing refractions depend on a trained refractionist being present with the subject and conducting an interactive form of subjective testing. A fully automated refraction system was installed in 13 optical dispensaries and after 15 months the patient and statistical information was gathered. The data from all operators were consistent and suggested a lack of operator effect on the refraction results. The mean of the SD of subjective sphere measurements was 0.2, or slightly less than a quarter dioptre, which would be an acceptable level of accuracy for ordering corrective lenses. The present study suggests an absence of operator influence on the results of the refractions and a degree of consistency and accuracy compatible with the prescription of lenses.

Abstract:
A refraction is one of several tests performed by optometrists and ophthalmologists to issue a patient’s prescription for glasses. In Alberta, optometrists and ophthalmologists are authorized to perform refractions and prescribe based on that refraction; however, opticians are only authorized to refract. This study investigates whether there is a public need for opticians to be licensed to perform refractions and prescribe based on that refraction based on the adequacy of the geographic distribution of eye care professionals in Alberta. To answer this question, the optometrist and ophthalmologist to population ratios for each of Alberta’s five health zones were calculated and compared to international benchmarks. Our results show that all five of Alberta’s health zones have optometrist to population ratios that either meet or exceed the 1:10,000 international benchmark, and three of the five health zones have ophthalmologist to population ratios that meet or exceed the 3:100,000 international benchmark. Based on this data, there is an adequate distribution of optometrists but an inadequate distribution of ophthalmologists in the province. However, in regard to refractions, there is no overwhelming public need for opticians to refract and prescribe based on the refraction.

Abstract:
Introduction. Previous cataract surgery studies assumed that first-eye predicted and observed postoperative refractions are equally important for predicting second-eye postoperative refraction. Methods. In a retrospective analysis of 173 patients having bilateral sequential phacoemulsification, multivariable linear regression was used to predict the second-eye postoperative refraction based on refractions predicted by the SRK-T formula for both eyes, the first-eye postoperative refraction, and the difference in IOL selected between eyes. Results. The first-eye observed postoperative refraction was an independent predictor of the second eye postoperative refraction () and was weighted more heavily than the first-eye predicted refraction. Compared with the SRK-T formula, this model reduced the root-mean-squared (RMS) error of the predicted refraction by 11.3%. Conclusions. The first-eye postoperative refraction is an independent predictor of the second-eye postoperative refraction. The first-eye predicted refraction is less important. These findings may be due to interocular symmetry.

Abstract:
AbstractIn order to reassess the relative importance of genetic and environmental factors in the development of myopia in Chinese schoolchildren, 90 pairs of MZ and 36 pairs of like-sex DZ twins were enrolled for detailed ophthalmological examination about their ocular refractions. Corneal curvatures and axial lengths were also measured. With equivalent settings of the range for concordance, corneal curvatures showed higher concordance rate (84%) than ocular refractions (65%) and axial lenghts (59%) in MZ twins. F-test on the intrapair variances between MZ and DZ twins revealed a significant hereditary role in determining the ocular refraction and its optical components. The degree of genetic determination was expressed by heritability indices, which were derived from intraclass correlation coefficients. The diversity of sample ages and refractions, while making the obtained data difficult to further explore the gene-environment interaction, led to the observation of more intrapair differences with age and myopic progression in MZ twins.

Abstract:
Refraction methods are often applied to model and image near-surface velocity structures. However, near-surface imaging is very challenging, and no single method can resolve all of the land seismic problems across the world. In addition, deep interfaces are difficult to image from land reflection data due to the associated low signal-to-noise ratio. Following previous research, we have developed a refraction wavefield migration method for imaging shallow and deep interfaces via interferometry. Our method includes two steps: converting refractions into virtual reflection gathers and then applying a prestack depth migration method to produce interface images from the virtual reflection gathers. With a regular recording offset of approximately 3 km, this approach produces an image of a shallow interface within the top 1 km. If the recording offset is very long, the refractions may follow a deep path, and the result may reveal a deep interface. We determine several factors that affect the imaging results using synthetics. We also apply the novel method to one data set with regular recording offsets and another with far offsets; both cases produce sharp images, which are further verified by conventional reflection imaging. This method can be applied as a promising imaging tool when handling practical cases involving data with excessively weak or missing reflections but available refractions.

ObjectiveTo identify associations between anthropometric indicators (height, weight and body mass index (BMI)) and both refraction and ocular biometrics in Chinese schoolchildren in Tianjin, China.DesignCross-sectional study.ParticipantsA total of 482 (86.07%) students (6–15 years old) with no history of ocular or systemic pathologies were enrolled in this study.MethodologyHeight and weight were measured using standardised protocols. Ocular biometrics (axial length (AL), vitreous chamber depth (VCD) and corneal curvature (CC)) were measured by a low-coherence optical reflectometry device. Cycloplegic refraction was measured using autorefraction. The AL/CC ratio and spherical equivalent refraction (SER) were calculated. Myopia was defined as SER ≤−0.50 dioptres (D). Multiple linear regression analysis was performed to explore the associations between anthropometric indicators (height, weight and BMI) and both refraction and ocular biometrics.ResultsThe overall prevalence of myopia was 71.16%. Overall, only height was associated with ALs, VCDs, AL/CC ratios and refractions after controlling for age, gender, parental myopia, family income, reading and writing distance and time spent outdoors. Furthermore, age-specific results demonstrated that height and weight were independently associated with refraction in participants aged 6–8 years and 9–11 years participants. Higher heights in schoolchildren were associated with longer ALs (regression coefficientb=+0.25 for each 10 cm difference in height, p<0.01), deeper VCDs (b=+0.23, p<0.01), higher AL/CC ratios (b=+0.04, p<0.01) and more negative refractions (b=−0.48, p<0.01). Heavier weights were also associated with longer ALs (+0.29 mm, p<0.01), deeper VCDs (+0.29 mm, p<0.01), higher AL/CC ratios (+0.04, p<0.01) and more negative refractions (−0.48 D, p<0.01).ConclusionsHeight and weight remained independently related to refraction and various ocular biometrics during the early adolescent growth period after adequately controlling for covariates, which could support the idea that a shared mechanism may regulate the coordinated growth of body and eye size in children.

Abstract:
The classical wavefront method for interpreting seismic refraction arrival times is implemented on a digital computer. Modern finite‐difference propagation algorithms are used to downward continue recorded refraction arrival times through a near‐surface heterogeneous velocity structure. Two such subsurface traveltime fields need to be reconstructed from the arrivals observed on a forward and reverse geophone spread. The locus of a shallow refracting horizon is then defined by a simple imaging condition involving the reciprocal time (the traveltime between source positions at either end of the spread). Refractor velocity is estimated in a subsequent step by calculating the directional derivative of the reconstructed subsurface wavefronts along the imaged interface. The principle limitation of the technique arises from imprecise knowledge of the overburden velocity distribution. This velocity information must be obtained from uphole times, direct and reflected arrivals, shallow refractions, and borehole data. Analysis of synthetic data examples indicates that the technique can accurately image both synclinal and anticlinal structures. Finally, the method is tested, apparently successfully, on a shallow refraction data‐set acquired at an archeological site in western Crete.

Abstract:
My aim in the written thesis is to scrutinize a particular stage in the process of image making by means of ideas generated by psychoanalytic theory, in particular Lacan’s concept of the gaze. I propose a three stage model of image making: 1) planning, 2) absorption or ‘un-thought’, and 3) judging; they are seen together as a spiral process. My primary interest is the second stage, both in my studio practice and in the written thesis. In the studio this can be seen in the conjunction between passages emphasizing energy, for instance passages emphasizing a ‘re-invigoration’ of the figure by means of an investigation into mark making and cartoon elements, and passages emphasizing form and colour. In the written work, by using Lacan’s concept of the gaze as template, then employing ideas such as ‘figure’ and ‘dissimulation’ within the libidinal economy (Lyotard), syncretistic scanning and the ability of the primary processes to learn and develop (Ehrenzweig), and the matrixial gaze (Lichtenberg-Ettinger), I aim to illuminate the ‘un-thought’ stage of image making by means of a consideration of libidinal as well as semiotic processes. By including aspects of schizoanalysis (Deleuze and Guattari), I ‘re-contextualize’ Lacan’s concepts of ‘lack’ and the empty signifier and retain his other ideas relating to his (late) concept of the gaze. Schizoanalysis, in providing an extended concept of the unconscious, aids in re-considering Lacan’s concept of the gaze within the context of the process of image making. Working from this basis I propose a grouping of (existing) ideas that I term the libidinal gaze, brought together for the purpose of reflecting on the un-thought stage in the process of image making. In doing so, I consider both concepts of perception as influenced by the processes and energy of the unconscious, and concepts of the unconscious as reflected through post-Freudian and post-Lacanian psychoanalytic thought.

Abstract:
Throughout the reading process, a narrative text produces various sensations of immediacy or distance. One important reason for this is that a narrative will in some places present situtations from a particular perspective, with which the reader is implicitly invited to identify, while in other places it will describe situations as independent of any perspective. If a perspective (that of the narrator, or that of a character in the text) is introduced, the narrative reflects an individual's (potentially fallible) perceptions, attitudes or beliefs; and this creates the impression of perspectival immediacy. If no perspective is introduced, on the other hand, the narrative pretends to relate "objective facts" within the fiction; and this creates the impression of perspectival distance. Thus the contrast between perepectivally situated and perepectivally non-situated sentences in a narrative produces perspectival refractions. The difference between both types of sentences, however, is often felt to be recalcitrant to a full linguistic analysis. For example, it is generally assumed that the perspectival status of a sentence is determined by the presence or absence of aubject-oriented elements in the sentence. But although such elements play an important role in focusing perspective, they need not occur in a sentence for the sentence to be perspectivally situated. In Chapter 1 of this dissertation, we draw attention to an observation which has received very little attention in the existing literature on perspective: per pectivally non-situated sentences typically move narrative time forward (in the sense that the order of the sentences on the page mimics temporal progression on the imaginary time line of the narrative), while perspectivally situated sentences do not convey forward movement in time. In other words, there appears to be a relationship between temporal ordering and perspective. Our aim is to specify the precise nature of this relationship. To do so, we first of all try to establish what determines the temporal relationship between consecutive sentences in narrative. We take as the starting point for our discussion some recent theories in the field of formal semantics which define this relationship in terms of the aspectual type a sentence belongs to. In Chapter 2, we explore to what extent these theories enable us to explain the apparent correlation between temporal ordering and perspective in narrative texts. In Chapters 3-5, we propose a detailed analysis of the relationship between the aspectual properties of sentences and their perspectival characteristics. Our central claim is that sentences exhibiting a state profile always introduce a perspective into a narrative. We try to make explicit why this is the case. In Chapter 6, the conclusions of this analysis are integrated into a more general theory of perspective in narrative fiction.

Abstract:
The thesis aims to analyse the relationship that F. T. Marinetti established between innovations in science at the fin-de-siècle and his Futurist movement. Chapter 1 examines the introduction and repercussions of Comtian Positivism in Italy. Chapter 2 provides a history of the relationship between science and literature in order to argue that Marinetti’s project was in certain respects related to the genre of ‘proto-science-fiction’. Following the more general theoretical and literary historical background of the first two chapters, Marinetti’s early French work as a Symbolist is read in Chapter 3 through representations of the neurological condition of synaesthesia in his and others poetry. The experience of simultaneity is investigated in Chapter 4 as a consequence of innovations in the study of electricity and in particular to the impact of the widespread use of Guglielmo Marconi’s wireless telegraph. In Chapter 5 Marinetti’s machine idolatry is contextualised as part of the late nineteenth century popular understanding of the first two laws of thermodynamics, the conservation of energy and entropy, which revolutionise the interpretation of the lifecycle. Finally, in Chapter 6, the discussion of thermodynamics in Marinetti’s Futurism is extended to an analysis of its links to debates on evolution and degeneration, and more specifically to the impact of a national ‘hygienic’ agenda for the purification of society.

Abstract:
In computer graphics a projection describes the mapping of scene geometry to the screen. While linear projections such as perspective and orthographic projection are common, increasing applications are being found for nonlinear projections, which do not necessarily map straight lines in the scene to straight lines on the screen. Nonlinear projections occur in reflections and refractions on curved surfaces, in art, and in visualisation. This thesis presents a new nonlinear projection technique called a trilinear projection that is based on the trilinear interpolation of surface normals used in Phong shading. Trilinear projections can be combined to represent more complicated nonlinear projections. Nonlinear projections have previously been implemented with ray tracing, where rays are generated by the nonlinear projections and traced into the scene. However for performance reasons, most current graphics software uses scanline rendering, where a scene point is imaged on a screen as a function of the projection parameters. The techniques developed in this thesis are of this nature. This thesis presents several algorithms used in trilinear projection: 1. An algorithm to analytically determine which screen locations image a given scene point. 2. An algorithm that correctly connects projected vertices. Each scene point may be imaged multiple times, which means a projected scene triangle may form from one to four different shapes of from two to nine vertices. Once connected, the projected shapes may be rendered with standard scanline algorithms. 3. An algorithm to more accurately render the curved edges between projected vertices. 4. A scene-space edge-clipping algorithm that handles continuity issues for projected shapes across composite projections. The trilinear projection technique is demonstrated in two different application areas: visualisation, and reflections and refractions. Specifically, various nonlinear projections that are congruent with pre-existing visualisation techniques are implemented with trilinear projections and a method for approximating the reflections and refractions on curved surfaces with trilinear projections is presented. Finally, the performance characteristics of the trilinear projection is explored over various parameter ranges and compared with a naive ray tracing approach.
