Waters Edge began with the inspiration to be closer to water and progressed into exploring architecture within the inhabitation of the riverscape through the vehicle of an urban kayak station. A 1:1 scaled kayak was constructed to materialize the conceptual research and provide a means to understand the relationship between built form and water. The necessity of each line and material component in the kayak construction manifested itself into the making of the urban kayak station. Further research into the St. Johns rowing regatta and boat making enhanced the social aspect of revitalizing Winnipeg’s river culture. A series of architectural models and drawings were constructed to explore the conceptualizations of the research and multiple iterations of the project emerged. The research concludes with further exploration into the way we inhabit the riverscape.

This thesis presents an investigation into the phenomena of scale effects on cavitation inception and noise of marine propellers. The overall aim is to extend the understanding of these phenomena and improve predicting methods. The investigations, which are largely experimental in nature, are restricted to the tip vortex and sheet types of cavitation. Chapter 1 includes a state-of-the-art review of the scale effect studies based on published papers to form the basis for the main objectives and structure of thesis. The objectives require systematic tests in a cavitation tunnel to explore the viscous scale effects contributing to the phenomena, particularly for the effect of the free-stream turbulence, and to include this effect in extrapolation procedures. Chapter 2 is concernedw ith the background flow measurementsin the cavitation tunnel under the effect of systematically varying levels of the free-stream turbulence generated by using wire meshes. This background information is obtained using a Laser Doppler Anemometry; measurements made with the latter provide a systematic basis on which the analyses of the cavitation inception and noise experiments can be performed. In Chapter 3, a set of cavitation inception tests is described with a NACA66 rectangular foil whose cross-section represents a typical blade section of a marine propeller. The inception measurements for systematically varying levels of the free-stream turbulence and that of the leading edge roughness are presented for different angles of attack and the results are discussed. Chapter 4 includes another set of cavitation inception experiments with a 5-bladed of model propeller of the Meridian Series. The measurements are taken for varying levels of the free-stream turbulence, blade roughness and dissolved gas contents. The results are analysed and discussed with a specific emphasis on the similarities between the effects of the free-stream turbulence and blade roughness. Chapter 5 presents a set of systematic noise measurements, with the same test propeller under the similar effects of the free-stream turbulence, blade roughness and dissolved gas content, using a single external hydrophone. The analyseso f these measurements,in terms of the tunnel background noise and net propeller noise, are presented and discussed for two operating conditions representing a typical non-cavitating and cavitating noise spectrum. In Chapter 6, a semi-empirical tool is developed to predict the inception of cavitation including the effect of the free-stream turbulence based on Lighthill's Leading Edge Correction factor (Lighthill, 1951). This tool is correlated with the inception tests results of the model propeller and its potential to be used as an extrapolator for the full-scale prediction is discussed. An attempt is made to establish a correspondence between the level of the free-stream turbulence and that of the blade roughness and its impact on the current test procedures is discussed. This chapter also includes an analysis of the similarity criteria to incorporate the effect of the free-stream turbulence in the inception of cavitation using the Dimensional Analysis procedure. In Chapter 7, a general review of the study together with the main conclusions from the thesis are presented and some recommendations for future work are made.

The film script Mangrove is both an eco-warrior thriller with science fiction elements and a documentation of the quirky, multicultural milieu of 21st century Auckland. It deals with the issues surrounding experimentation with genetic engineering and human alienation and disability.The script references the tradition of New Zealand film and its development as a "cinema of unease" through the character of Nat, who lives as a "man alone" on a moored yacht, and through its setting in a desolate mangrove estuary adjacent to a suburban industrial estate. It features characters who are recent immigrants from varying cultures and offers insights to world views that contrast with the pessimistic colonial outlook on life that pits man against the environment in a struggle for domination.The title, Mangrove, is a metaphor for the rich human environment that can be found in outposts of society that are often maligned and overlooked for their perceived lack of value.Mangrove's main character, Talia, is a disabled woman whose desire is to be accepted for her difference, her insights and her humanity. She is confronted with her past and her origins that may be part of a late 20th century genetic experiment.She meets Nat, a former journalist hiding out from society who is searching for a way to express his idealism. Likewise, Shiva, an indo-Fijian living in a nearby car wreckers yard has a love of music and the environment and shares Nat's idealism and desire to work for a better world. The three uncover a potentially world-altering genetic experiment with sugar. The antagonist multinational has Russian mafia allies that have to be dealt with, while the protagonists have the assistance of some Thai monks and Pacific Island street kids as they strive to expose the experimentation, and work out their relationships with one another.

Edge-cloud brings the computation power as close to the clients as possible. This reduces latencies and overall computation time in the cloud. Thanks to the mobile nature of clients we must be able to migrate tasks among different servers. The goal of this thesis is to examine possible problems in communication and propose the architecture of framework. Our framework uses gRPC and is written as module to it. It is platform independent, uses reliable communication and focuses on easy usage. We provide implementation of this framework with some example uses. 1

An edge response characterization technique to predict the ITF of an interferometer using non- interferometric measurements has been shown to be effective. This technique eliminates the need for phase objects to be used in the characterization process. Using coherent imaging with an irradiance sensitive detector and an irradiance step as a characterization artifact to determine an interferometer's ITF was proven viable for diffraction limited, defocused, astigmatic, and spherically aberrated systems. Simulations and collected data demonstrated agreement between the interferometric edge response characterization technique results and coherent imaging edge response characterization technique results. The effect that aberrations have on ITF curves has been investigated in this thesis and an understanding of the system behavior under aberrated conditions was investigated.

This thesis discusses the two dimensional allotrope of carbon known as graphene in presence of magnetic field, with special focus on edge states. The structure of graphene is described in detail and from the structure, two models are formed. The Dirac equation is a good description of graphene for large samples, far away from edges, where the boundaries can be ignored. However, it causes problems with most types of edge and hard wall approximation has to be implemented. The Dirac equation is described in detail and used to obtain an energy spectrum, wavefunction and density of states for graphene edge in a strong magnetic field. For comparison, a Bohr-Sommerfield approximation was used to find the dispersion relation and compare it to the results obtained numerically from the Dirac equation. The second model, better fitting for nano-scale systems, is the tight binding model. This model was utilized to find Energy spectrum for graphene flakes in magnetic field, which resembles Hofstadter's butterfly spectrum. The spectrum was analyzed and periodic oscillations of magnetisation dependent on magnetic field (known as the de Haas-van Alphen effect) were described. The oscillation of magnetisation depends on the shape of the dot, even though the main properties remain the same: at low magnetic field, periodic oscillations due to Aharonov-Bohm effect, turning into more chaotic oscillations depending on the boundary conditions of the given quantum dot.

Dense stereo matching is one of the most extensively investigated topics in computer vision, since it plays an important role in many applications such as 3D scene reconstruction. In this thesis, a novel dense stereo matching method is proposed based on edge-aware truncated minimum spanning tree (T-MST). Instead of employing non-local cost aggregation on traditional MST which is only generated from color differences of neighbouring pixels, a new tree structure, "Edge-Aware T-MST", is proposed to aggregate the cost according to the image texture. Specifically, cost aggregations are strongly enforced in large planar textureless regions due to the truncated edge weights. Meanwhile, the "edge fatten" effect is suppressed by employing a novel hybrid edge-prior which combines edge-prior and superpixel-prior to locate the potential disparity edges. Then a widely used Winner-Takes-All (WTA) strategy is performed to establish initial disparity map. An adaptive non-local refinement is also performed based on the stability of initial disparity estimation. Given the stereo images from Middlebury benchmark, we estimate the disparity maps by using our proposed method and other five state-of-the-art tree-based non-local matching methods. The experimental results show that the proposed method successfully produced reliable disparity values within large planar textureless regions and around object disparity boundaries. Performance comparisons demonstrate that our proposed non-local stereo matching method based on edge-aware T-MST outperforms current non-local tree-based state-of-the-art stereo matching methods in most cases, especially in large textureless planar regions and around disparity bounaries.

This thesis explores finite-size effects on the spin-wave excitations of one-dimensional ferromagnetic and antiferromagnetic systems. Specifically, it presents a theoretical study of the scattering function, the physical observable in inelastic neutron and photon scattering experiments, under the influence of extra magnetic anisotropy energy localized at the system’s boundaries. The method for calculating spin wave scattering functions in bulk is adapted to the finite system case, enabling explicit numerical calculations with edge effects. Our results show a significant broadening of the scattering peaks of low energy spin waves in ferromagnetic and antiferromagnetic systems. We show that broadening is due to the emergence of spin excitations localized at the edge of the system, the so-called edge modes. / Graduate
