<p>The Summer Olympics occur every four years, capturing the hearts of the world for a nite period of time. During this time, the eyes of the world are set on the host city of whom provide a facility and an infrastructure to accommodate not only the athletes, but the millions of spectators that attend the events and the memorable moments that ensue.  While the Summer Olympics and it’s park are focused heavily upon during the games, integration of the site into the host city has become largely forgotten post-Olympics. Ultimately, these once vast locations have now become deserted and dystopia environments within the host city. This thesis addresses the problem of integrating Olympic parks back into the context of the host city by enabling new and diverse spaces. The work of Charles Waldheim, Rem Koolhaas, Alex Wall, Tricia Cusack and Dennis Saunders are employed over five main ideas: wetland urbanism, urban grid, edge extension, fragmented distribution and landscape occupation.  Strategic integration of post-Olympic Sites into the existing host city can arguably be done so by creating a multi-programmatic system that adapts and transforms to respond to the dynamic needs of both the Olympic Site and the local urban context of the surrounding city.  This thesis considers the task of integrating the Sydney Olympic Park back into Sydney’s context, transforming its current form into a state of integration with the host city that is successful. The thesis produces a design, based on five key design principles which have been created through conclusions of research: wetlands, extension, grid, distribution and occupation.</p>

AbstractFlow visualization experiments were conducted in a water channel and a low-speed wind tunnel at Reynolds number of 1.54 $$\times$$ × 104 to 1.2 $$\times$$ × 105 for a leading-edge extension model, which is referred to as a NASA TP-1803 model in this study. In addition, particle image velocimetry velocity measurements were taken in the water channel to obtain the quantitative information about the three-dimensional velocity field over the strake and wing surfaces. The results obtained at low, medium and high angles of attacks represent three distinct cases of interaction between the strake and wing vortices. Namely, at α = 5o and 10° the strake and wing vortices were developed over the wing surface without significant interaction noticed; at α = 20°, the strake vortex strongly interacted with the wing vortex in an intertwining manner, which was sensitive to Reynolds number; at α = 30°, the breakdown of the strake vortex took place close to the junction of the strake and the wing; thus, the interaction of the strake and the wing vortices appeared to be less significant than the case of α = 20°.

In this article, a blockwise regression-based image inpainting framework is proposed. The core idea is to fill the unknown region in two stages: Extrapolate the edges to the unknown region and then fill the unknown pixels values in each sub-region demarcated by the extended edges. Canny edge detection and linear edge extension are used to respectively identify and extend edges to the unknown region followed by regression within each sub-region to predict the unknown pixel values. Two different regression models based on K-nearest neighbours and support vectors machine are used to predict the unknown pixel values. The proposed framework has the advantage of inpainting without requiring prior training on any image dataset. The extensive experiments on different images with contrasting distortions demonstrate the robustness of the proposed framework and a detailed comparative analysis shows that the proposed technique outperforms existing state-of-the-art image inpainting methods. Finally, the proposed techniques are applied to MRI images suffering from susceptibility artifacts to illustrate the practical usage of the proposed work.

Intramolecular methyl–methyl coupling on Au (111) is explored as a new on-surface protocol for edge extension in graphene nanoribbons (GNRs). Characterized by high-resolution scanning tunneling microscopy, noncontact atomic force microscopy, and Raman spectroscopy, the methyl–methyl coupling is proven to indeed proceed at the armchair edges of the GNRs, forming six-membered rings with sp3- or sp2-hybridized carbons.

We present an image processing algorithm based on edge extension to correct the influence of atmospheric dispersion. The Elden model is used to estimate the image dispersion index caused by atmospheric dispersion and the image affected by the atmospheric dispersion is regarded as the results of the original image convolution operation. When the direct convolution is used to compensate the blur of star, border effect and ill-posed problem make the result unacceptable. To solve these problems, we use image preprocessing and perform an edge extension method for images before the convolution. The simulated analysis and experimental results from a 300 mm telescope system show that the proposed method can effectively correct the influence of atmospheric dispersion even under relatively low signal to noise ratio (SNR<2). Compared with the traditional prism correction and fiber correction methods, this technique can greatly reduce the complexity of the optical system.
