Reducing position error of cantilevered loads in motion systems

The positioning error of a large cantilevered mass that is actuated at its supported end is minimized as this mass travels at challenging high speeds and accelerations. An integrated approach is adopted to realize the task. After selecting the appropriate actuator that would provide higher rigidity, the system is viewed as a multi-degree of freedom system, and hence the concept of system-generated disturbance is introduced. This allows the use of appropriate mechanical design considerations and a proper generation of the kinematics commands to minimize such disturbance. A disturbance observer is then designed to detect and compensate the remaining disturbance, hence minimizing the positioning error.

New world orders in contemporary children's literature : utopian transformations

"New World Orders shows how texts for children and young people have responded to the cultural, economic, and political movements of the last 15 years. With a focus on international children's text produced between 1988 and 2006, the authors discuss how utopian and dystopian tropes are pressed into service to project possible futures to child readers. The book considers what these texts have to say about globalisation, neocolonialism, environmental issues, pressures on families and communities, and the idea of the posthuman."--BOOK JACKET.

Poetry in motion : Ko Un and Korean democratisation

This essay focuses on the poet and intellectual Ko Un, a prominent nationalist and critic of successive authoritarian regimes in Korea. Ashis Nandy gleaned insights into colonial India by investigating the lives of individuals who were emblematic of British colonialism. For instance Nandy focused on Rudyard Kipling to explain how colonialism damaged both Indians and the English who were complicit to it. Similarly, I intend to use the life and literary output of Ko Un to glean insights into Korea’s fight for democracy in the context of the onset of modernisation. Through his political activism and writing Ko celebrated the lives of ordinary Koreans, including his one-time prison mate Kim Dae-jung and numerous political activists, workers, and farmers. He linked their struggle for democracy to a much longer quest to preserve what he considered to be the unique and invaluable aspects of the Korean national character.

Narrativization of actuality : convergence of form and genre in film and television

The thesis concerns the treatment of actuality in film and television, particularly the narrativization of actuality images, and the context of their placement within audio/visual texts. Several instances of the convergence of media form and genre are analyzed, and the conventions of classificatory systems and boundaries that pertain to film and television representations are reconsidered in light of changes in the conventions of genre. The distinction between, and convergence of fictional and non-fictional conventions of narrative are therefore central to the thesis, as are the related issues of viewer response, the nature of subjectivity in the viewer, the connectivity of text and culture, and the relations of actuality to the text. The thesis traces the narrativization of actuality through textual, formal and genre boundaries, adopting a ‘line of flight or deterritorialization’ that enables the thesis to ‘change in nature and connect with other multiplicities.’This line of flight passes through the conventional separation of genre groupings and texts, and, similarly, has been applied in the thesis as a rationale for the diminution of theoretical boundaries. A multiperpectival approach is applied to the permeability of, or transcendent relations of the analysis to the boundaries between genres, between texts and culture, and between actuality and virtual representation. In the thesis there is also a theoretical deterritorialization that consents to a pluralism of theory, which is an approach demonstrated by Deleuze and Guattari in A Thousand Plateaus. The model of multi-perspectivalism adopted in the thesis engages in establishing connections and similarities between theories, rather than emphasizing contradictory and exclusive practices. The Foucauldian notion of the rules of formation in discourse, Nichols’ theories of documentary representation of reality, Bordwell’s schematic interpretation, and several other positions are critiqued, as the line of flight embarked upon in the thesis intersects with, and passes through both textual and theoretical boundaries. The thesis consists of two parts: firstly, a location of theoretical perspective, in which the issues of theory pertaining to actuality and narrative are explicated, and the methodological approach of the thesis is defined. The second part commences with an analysis of the most familiar instances of actuality in film and television, with particular attention to documentary forms. It then engages in the analysis of films that represent actuality but which, in the process of narrativization, display a convergence of genre conventions. The films selected for analysis include Steven Speilberg's Schindler's List, (1993) Oliver Stone's JFK, (1991) and Robert Zemeckis' Forrest Gump, (1994) and Contact, (1996). Hence the thesis is concerned with the application of a pluralist theoretical approach, with, however, an emphasis on the Deleuzo-Guattarian notions of rhizome and assemblage. Within this theoretical frame, the connections between actuality and the audio/visual text are explicated, and the formation of text as ‘a rhizome with the world’, is analyzed across a range of examples.

Developing a relationship with place : art in the context of bioregional theory and practice

Investigates a proposed solution to Western culture's essentially separatist and destructive relationship with the earth from the perspective of the artist. Examines the author's bioregional philosophical model which is based on a belief in the importance of place in physical and spiritual well-being and argues that it is an appropriate one to apply in the context of contemporary Australian art practice.

Celluloid dreaming : cultural myths and landscape in Australian film 1970-1990

Examines the way in which cultural myths in selected Australian feature films of the 1970s and 1980s reflect changing attitudes towards nationalism, Australian identity, gender roles, mateship and how the Australian settler culture defines (or fails to define) its relationship with indigenous Australians.

Representation and judgement : 'privileged' Jews in Holocaust writing and film

This thesis analyses the ways in which moral judgements of so-called privileged Jews are constructed in Holocaust representations. ‘Privileged’ Jews include those prisoners in the camps and ghettos who held positions which gave them access to material and other benefits. Subject to extreme levels of coercion, these victims were compelled to act in ways that have often been judged as both self-serving and harmful to fellow inmates. Such controversial figures constitute an intrinsically important, frequently misunderstood and hastily judged facet of the Holocaust. Scholars have neglected the problem of judgement in relation to ‘privileged’ Jews; nonetheless, Holocaust texts frequently portray these liminal figures.

Of crucial importance to the thesis is Primo Levi’s paradigmatic essay entitled ‘The Grey Zone,’ which directly engages with the complex and sensitive issue of ‘privileged’ Jews. Levi argues that due to the extreme ethical dilemmas that ‘privileged’ Jews confronted, any judgement of these victims needs to be suspended. However, if, as Levi suggests, judgement is at times impossible, the thesis challenges Levi’s assumption by contending that representations of ‘privileged’ Jews inevitably take a moral position. In this way, the thesis conceptualises judgement as a ‘limit’ of representation. Indeed, it is shown that Levi himself cannot abstain from judging those for whom he argues judgement should be suspended.

The thesis takes Levi’s concept of the ‘grey zone’ as a point of departure in order to examine the problems of judgement and representation in relation to ‘privileged’ Jews. Analysis focuses on Raul Hilberg’s influential historical work and examples of documentary and fiction films. The thesis examines how Hilberg and several filmmakers employ conventions as a means of conveying judgement. It is argued that self-reflexive representations of ‘privileged’ Jews in film, particularly fictional dramatisation, have the potential to provide a nuanced representation of ‘privileged’ Jews, which engages with Levi’s ideas by questioning the possibility of judgement.

Individual differences in affective responses to violence and sexual violence

The thesis aimed to identify and compare individual differences in anger related affective responses upon exposure to neutral, violent and sexually violent film. The findings revealed that both graphic and non-graphic sexually violent film content may have a stronger impact on viewers' anger levels than exposure to standard violent film. The portfolio examined in four case studies the utility of the Violence Risk Scale when seeking to identify factors associated with risk of violent recidivism and subsequent treatment targets for intellectually disabled offenders . Treatment indications must consider the impaired cognitive and adaptive abilities and the difficulties inherent in modifying the behavioural characteristics of intellectually disabled offenders.

Plane wave scattering by a spherical di-electric particle in motion : a relativistic extension of the Mie theory

Light scattering from small spherical particles has applications in a vast number of disciplines including astrophysics, meteorology optics and particle sizing. Mie theory provides an exact analytical characterization of plane wave scattering from spherical dielectric objects. There exist many variants of the Mie theory where fundamental assumptions of the theory has been relaxed to make generalizations. Notable such extensions are generalized Mie theory where plane waves are replaced by optical beams, scattering from lossy particles, scattering from layered particles or shells and scattering of partially coherent (non-classical) light. However, no work has yet been reported in the literature on modifications required to account for scattering when the particle or the source is in motion relative to each other. This is an important problem where many applications can be found in disciplines involving moving particle size characterization. In this paper we propose a novel approach, using special relativity, to address this problem by extending the standard Mie theory for scattering by a particle in motion with a constant speed, which may be very low, moderate or comparable to the speed of light. The proposed technique involves transforming the scattering problem to a reference frame co-moving with the particle, then applying the Mie theory in that frame and transforming the scattered field back to the reference frame of the observer.

Localisation of an object in motion in 3D space via angle only measurements

In this paper, we discuss an approach to localisation of a moving object in 3D space. The method used to track this object is angle only measurements obtained via radar elements strategically placed within the X, Y and Z planes. In addition, computer simulations are conducted to verify the theoretical assertions presented with respect to the application employing an Extended Kalman Filter.
