This thesis explores the search for the sublime in a contemporary context. The 'Wilderness' can be viewed as a metaphysical space which can only be circumscribed. The dust storms of the Australian continent provides the space where in this experience is located, metaphorically. If the perceptions of reality are to be seen as filtered through the experiences and conditions of the human spirit, the sites or 'Stations' as the author has called them layer and reveal a personal reflection on the timelessness and commonality of the human condition. Space and time seem to collapse folding over and into itself, with a layering of memories and senses. Growing up in the Mallee in Victoria the author's formative years were shaped particularly by the land and the elements. In these works, the sense of identity is enveloped into a rather cosmic sense of being, when the author became inseparable from the red earth, its duststorms, the sense of space and the feeling of isolation. The most constant experience is that of the sense of interconnectedness and of being able to reach down and stroke the land from a distant vantage point. Consequently, the spiritual found in nature has been a re-occurring motif in the author's artistic practice. The location of the duststorm entitled 'God's Breath', is in flying over Adelaide, towards the Mallee. The grid indicates the impositions of perception which is projected on the land by the viewer, often from a cultural or political viewpoint. In this case the author's perception is influenced by the auto-biographical gaze and the duststorm itself becomes a metaphor for memory and interiority. The medium of wax as a preserving substance is used in the artworks, however this can be seen as being an agent of change, able to re-define it's form according to environmental conditions. The land as 'Self' or 'Mother' is not a constant location, but as in the 'Wilderness' can be seen as a spiritual and/or psychological space, a multi-dimensional filter for the senses and the mind, wherein the spirit can be expanded and be still in it's receptiveness. The four wax rectangles are representative of a duststorm, as seen from the interior perspective of the sensory. These works suggest a multitudinal level of experiences, not necessarily definable but open ended in concept. The void as a creative fullness nurtures the more transient moments of the sensory and temporal. From scarification and pain, through breath and loss, the journey through the wilderness results in a melodic tonal experience, indicative of memory, place and identity / Master of Arts (Hons) (Visual Arts)

Renewed interest in returning to the Moon, emboldened by recent directives and missions by NASA, has necessitated the establishment of lunar infrastructure to support continuous human presence. With that, the objective of making this return more cost effective has gained significant importance. Low energy lunar transfers are more efficient ways to reach the Moon than the traditional Hohmann-type transfer. These trajectories leverage the multi-body gravitational effects to reduce overall delta-v requirements, in some cases removing the capture delta-v completely. While the time of flight for these transfers can be much longer than a Hohmann-type transfer, the chaotic design space of these transfers can enable large changes in arrival conditions at the Moon for small changes in initial conditions. Many investigations of these transfers take place in simplified dynamical models, such as the Planar Circular Restricted Three Body Problem, with very few higher-fidelity models being implemented. This approach is good to understand the dynamics of these trajectories as well as provide initial guesses for higher-fidelity models; but approximating the dynamics heavily make these models less applicable to mission design. This thesis aims to investigate the application of a higher-order model to simulate these trajectories. STK Astrogator was used to recreate the NASA GRAIL trajectory; and from the recreated trajectory, a nominal trajectory absent of mid-course corrections was established. This nominal trajectory was used to perform parametric and variational studies of departure and arrival conditions as well as compare to a nominal trajectory in a reduced-fidelity model. An investigation into the post launch correction burn requirements following launch vehicle under-performance was completed. Utilizing low energy transfers proved beneficial to adjusting arrival conditions for low delta-v requirements. All arrival inclinations are reasonably achievable for around 255 m/s. Using 255 m/s as a baseline, right ascension of the ascending node could be reached in a 40 degree range and argument of periapsis in a 50 degree range. Lunar insertion arrival can be varied by 7 hours on either side for less than 80 m/s. Trans-lunar injection epoch can be varied by 7 hours on either side of nominal departure for less than 4 m/s. Orbit radius and initial velocity are the most expensive errors to correct. These trajectories can be tuned to reduce the overall mid-course correction delta-v requirement for differing arrival inclinations if other orbital elements are relaxed. A relationship between placement of post-launch correction maneuver for velocity or radius errors was found. Comparing the trajectory in STK to the Inclined Bi-Elliptic Restricted Four Body problem, revealed that timing of the trajectory is variable while keeping the same arrival and departure conditions. However, solar radiation pressure cannot be ignored for more accurate simulation of these trajectories. This investigation has shown that low energy lunar transfers are a viable method to reach the Moon and their chaotic nature can be leveraged to relax restrictions in the design space. / Master of Science / Returning to the Moon has become a more important goal within the space industry. This has required more cost-efficient ways to reach the Moon; an important cost savings being fuel. Traditional ways to reach the Moon required large amounts of fuel to be expended to remain around the Moon after launch. Low energy lunar transfers aim to reduce fuel usage while still reaching the Moon, although they take much longer to reach their destination. Fuel and energy have direct comparisons and are used to evaluate these transfers. These transfers are highly susceptible to changes in their trajectory making them ideal for transferring to the Moon in different orientations. These changes can be made using very little fuel, allowing for more resources to be brought to the Moon. Navigating these transfers to the Moon require an accurate model of space for mission design.

O recorte temático desta tese são a Vita Apostolica e o Mistério Sacramental como sentido existencial e missão cristã para os homens do Ocidente Europeu na Idade Média Central (séculos XI-XIII) O documento a ser investigado é a versão alemã de Heidelberg do roman arturiano A Demanda do Santo Graal, cujo manuscrito germânico original foi compilado ao final do século XIII. O corpus corresponde ao códice 147 da Bibliotheca Palatina Germaniae de Heidelberg, não se tratando de mera versão dos originais bretões para o alemão medieval (Mittelhochdeutsch). A presente fonte constitui um corpus inaugural, um texto propriamente alemão, ainda que filiado ao Ciclo da Vulgata (Ciclo do Pseudo-Gautier Map), que correspondeu ao primeiro ciclo de prosificação das narrativas do Graal. Pretende-se perscrutar um elemento central do imaginário que caracterizou a experiência dos homens do Ocidente Europeu no apogeu da Idade Média Central. Tratase do sacramento, e a compreensão do sentido sacramental da existência humana no plano da imanência constitui relevante senha de compreensão e predicação de significado às experiências concretas destes homens. Isso se pode atingir por intermédio da apreensão do elemento axial de seu imaginário. / The thematic cutting of this dissertation are the Vita Apostolica and the sacramental mystery as life meaning and Christian mission for the people of the European Western World during the Central Middle Ages (11th to 13th centuries). The document to be analysed is the German version of the Arthurian romance The Quest of the Holy Grail, whose original German manuscript was compiled by the end of 13th century. The corpus corresponds to the codex 147 pertaining to the Bibliotheca Palatina Germaniae in Heidelberg, and this is no sheer translation of the original Bretonnic version to Middle German (Mittelhochdeutsch). The present source constitutes an original corpus, a properly German text, although linked up to the Vulgate Cycle (Pseudo-Gautier Map Cycle), which corresponds to the first prosification cycle entailing the Grail narratives. This study aims at scruting a central element of the imaginary concerning the historical experience of people of Western European World at the peak the Central Middle Ages. It is the sacrament, and the comprehension of the sacramental meaning of human life in the sphere of immanence builds up a relevant key to understanding and endowing concrete experiences with meaning. This can be achieved by means of aprehending the shaft element concernig their imaginary.

<p>In this thesis an approach to visualize internal behaviour of object oriented software is developed.</p><p>The runtime information, which can be described as objects calling other objects, is displayed as a graph consisting of nodes and edges. The aim is to design an application in Java, which takes the runtime information in form of an object call graph and visualizes it as a tree and as a force directed view.</p><p>Therefore, first a data model has to be designed, holding an object call sequence. Furthermore, a discussion about graph definition languages and according tools is made. After this different graph layout algorithms are examined as well as graph displaying tools. Finally, the implementation of this visualization program deals with the combination of these three components graph data extraction, graph layout calculation and graph visualization.</p>

<p>Reverse Engineering of software is a complex task. It is supported by various analyses and the computation of certain software quality metrics. To get an overview of the structure of the analysed software it is often necessary to visualize the relations between different components of software.</p><p>The VizzAnalyzer tool was developed for these purposes and allows visualizing the internal structure of software systems as UML2.0 class diagrams. The existing Eclipse-based visualization plug-in does not allow to automatically lay out the computed graph. Applying the layout manually is not feasible for larger graphs. A proper layout is needed to understand the provided information intuitively and the usefulness of the visualization is, on top of that, strongly connected to its layout.</p><p>In this thesis, we first state requirements for the development and implementation process of a suitable layout algorithm. We further describe the development, design, and implementation of the Sugiyama layout algorithm into the existing Eclipse-based visualization plug-in. We add these new functionalities to be able to automatically compute a layout for given UML2.0 class diagrams achieving a proper Sugiyama layout for this type of diagrams.</p><p>At the end of this thesis, we compare the results achieved by the implemented algorithm with the results achieved by yEd given the same diagrams as input.</p>
