Bone loss may result from remodelling initiated by implant stress protection. Quantifying remodelling requires bone density distributions which can be obtained from computed tomography scans. Pre-operative scans of large animals however are rarely possible. This study aimed to determine if the contra-lateral bone is a suitable control for the purpose of quantifying bone remodelling. CT scans of 8 pairs of ovine tibia were used to determine the likeness of left and right bones. The deviation between the outer surfaces of the bone pairs was used to quantify geometric similarity. The density differences were determined by dividing the bones into discrete volumes along the shaft of the tibia. Density differences were also determined for fractured and contra-lateral bone pairs to determine the magnitude of implant related remodelling. Left and right ovine tibiae were found to have a high degree of similarity with differences of less than 1.0 mm in the outer surface deviation and density difference of less than 5% in over 90% of the shaft region. The density differences (10–40%) as a result of implant related bone remodelling were greater than left-right differences. Therefore, for the purpose of quantifying bone remodelling in sheep, the contra-lateral tibia may be considered an alternative to a pre-operative control.

Texture analysis and textural cues have been applied for image classification, segmentation and pattern recognition. Dominant texture descriptors include directionality, coarseness, line-likeness etc. In this dissertation a class of textures known as particulate textures are defined, which are predominantly coarse or blob-like. The set of features that characterise particulate textures are different from those that characterise classical textures. These features are micro-texture, macro-texture, size, shape and compaction. Classical texture analysis techniques do not adequately capture particulate texture features. This gap is identified and new methods for analysing particulate textures are proposed. The levels of complexity in particulate textures are also presented ranging from the simplest images where blob-like particles are easily isolated from their back- ground to the more complex images where the particles and the background are not easily separable or the particles are occluded. Simple particulate images can be analysed for particle shapes and sizes. Complex particulate texture images, on the other hand, often permit only the estimation of particle dimensions. Real life applications of particulate textures are reviewed, including applications to sedimentology, granulometry and road surface texture analysis. A new framework for computation of particulate shape is proposed. A granulometric approach for particle size estimation based on edge detection is developed which can be adapted to the gray level of the images by varying its parameters. This study binds visual texture analysis and road surface macrotexture in a theoretical framework, thus making it possible to apply monocular imaging techniques to road surface texture analysis. Results from the application of the developed algorithm to road surface macro-texture, are compared with results based on Fourier spectra, the auto- correlation function and wavelet decomposition, indicating the superior performance of the proposed technique. The influence of image acquisition conditions such as illumination and camera angle on the results was systematically analysed. Experimental data was collected from over 5km of road in Brisbane and the estimated coarseness along the road was compared with laser profilometer measurements. Coefficient of determination R2 exceeding 0.9 was obtained when correlating the proposed imaging technique with the state of the art Sensor Measured Texture Depth (SMTD) obtained using laser profilometers.

What is it like to be a master of the universe? The authors have researched the desires and fears of the world's most powerful men. The Murdochs, Packers, Kennedys, Agnellis and other men like them, directly determine the fates of thousands and influence the future of the world like no other people. Described as 'sacred monsters' by one of their own, they are carefully created to be what they are and to enjoy shaping the world in their own likeness. To learn about these often reclusive men, the authors extended the life-history technique to interrogate autobiographies, diaries and biographies and have created a composite picture, a collective portrait, of tycoons over three generations. The book carefully explores the childhoods, schooling, work and play, sexual activities, marriages and deaths of the wealthiest men who have ever lived. It exposes the nature of ruling-class masculinity itself.

Titled "An Essay on Antimetaphoric Resistance", the dissertation investigates what is here being called "Counter-figures": a term which has in this context a certain variety of applications. Any other-than-image or other-than-figure, anything that cannot be exhausted by figuration (and that is, more or less, anything at all, except perhaps the reproducible images and figures themselves) can be considered "counter-figurative" with regard to the formation of images and figures, ideas and schemas, "any graven image, or any likeness of any thing". Singularity and radical alterity, as well as temporality and its peculiar mode of uniqueness are key issues here, and an ethical dimension is implied by, or intertwined with, the aesthetic. In terms borrowed from Paul Celan's "Meridian" speech, poetry may "allow the most idiosyncratic quality of the Other, its time, to participate in the dialogue". This connection between singularity, alterity and temporality is one of the reasons why Celan so strongly objects to the application of the traditional concept of metaphor to poetry. As Celan says, "carrying over [übertragen]" by metaphor may imply an unwillingness to "bear with [mittragen]" and to "endure [ertragen]" the poem. The thesis is divided into two main parts. The first consists of five distinct prolegomena which all address the mentioned variety of applications of the term "counter-figures", and especially the rejection or critique of either metaphor (by Aristotle, for instance) or the concept of metaphor (defined by Aristotle, and sometimes deemed "anti-poetic" by both theorists and poets). Even if we restrict ourselves to the traditional rhetorico-poetical terms, we may see how, for instance, metonymy can be a counter-figure for metaphor, allegory for symbol, and irony for any single trope or for any piece of discourse at all. The limits of figurality may indeed be located at these points of intersection between different types of tropes or figures, and even between figures or tropes and the "non-figurative trope" or "pseudo-figure" called catachresis. The second part, following on from the open-ended prolegomena, concentrates on Paul Celan's poetry and poetics. According to Celan, true poetry is "essentially anti-metaphoric". I argue that inasmuch as we are willing to pay attention to the "will" of the poetic images themselves (the tropes and metaphors in a poem) to be "carried ad absurdum", as Celan invites us to do, we may find alternative ways of reading poetry and approaching its "secret of the encounter", precisely when the traditional rhetorical instruments, and especially the notion of metaphor, become inapplicable or suspicious — and even where they still seem to impose themselves.

Dissertation considers the birth of modernist and avant-gardist authorship as a reaction against mass society and massculture. Radical avant-gardism is studied as figurative violence done against the human form. The main argument claims avant-gardist authorship to be an act of masculine autogenesis. This act demands human form to be worked to an elementary state of disarticulateness, then to be reformed to the model of the artist's own psychophysical and idiosyncratic vision and experience. This work is connected to concrete mass, mass of pigment, charcoal, film, or flesh. This mass of the figure is worked to create a likeness in the nervous system of the spectator. The act of violence against the human figure is intended to shock the spectator. This shock is also a state of emotional and perceptional massification. I use theatrical image as heuristic tool and performance analysis, connecting figure and spectator into a larger image, which is constituted by relationships of mimesis, where figure presents the likeness of the spectator and spectator the likeness of the figure. Likeness is considered as both gestural - social mimetic - and sensuous - kinesthetically mimetic. Through this kind of construction one can describe and contextualize the process of violent autogenesis using particular images as case studies. Avant-gardist author is the author of theatrical image, not particular figure, and through act of massification the nervous system of the spectator is also part of this image. This is the most radical form and ideology of avant-gardist and modernist authorship or imagerial will to power. I construct a model of gestural-mimic performer to explicate the nature of violence done for human form in specific works, in Mann's novella Death in Venice, in Schiele's and Artaud's selfportaits, in Francis Bacon's paintings, in Beckett's shortplat NOT I, in Orlan's chirurgical performance Operation Omnipresense, in Cindy Sherman's Film/Stills, in Diamanda Galás's recording Vena Cava and in Hitchcock's Psycho. Masspsychology constructed a phobic picture of human form's plasticity and capability to be constituted by influencies coming both inside and outside - childhood, atavistic organic memories, urban field of nervous impulses, unconsciousness, capitalist (image)market and democratic masspolitics. Violence is then antimimetic and antitheatrical, a paradoxical situation, considering that massmedias and massaudiences created an enormous fascination about possibilities of theatrical and hypnotic influence in artistic elites. The problem was how to use theatrical image without coming as author under influence. In this work one possible answer is provided: by destructing the gestural-mimetic performer, by eliminating representations of mimic body techniques from the performer of human (a painted figure, a photographed figure, a filmed figure or an acted figure, audiovisual or vocal) figure. This work I call the chirurgical operation, which also indicates co-option with medical portraitures or medico-cultural diagnoses of human form. Destruction of the autonomy of the performer was a parallel process to constructing the new mass media audience as passive, plastic, feminine. The process created an image of a new kind of autotelic masculine author-hero, freed from human form in its bourgeois, aristocratic, classical and popular versions.
