title: High performance simulation for ATM network development

authors: Cleary, John G.

subjects: computer science

abstract: Techniques for measuring and modeling ATM traffic are reviewed. The requirements for cell level ATM network modeling and simulation are then outlined followed by a description of an ATM traffic and network (ATM-TN) simulator. This ATM-TN simulator is built upon parallel simulation mechanisms to achieve the high performance needed to execute the huge number of cell events required for a realistic network scenario. Results for several simulation experiments are reported using this high performance simulation including scenarios for the Wnet and OPERA networks. Finally, a preliminary evaluation of the application of high performance simulation to the design and analysis of ATM network performance is provided.

title: The Modern Dragon: Contemporary Representations from Tolkein to Present

authors: Sheridan, Brendan Daniel

subjects: Dragon

abstract: ‘Every century has its dragons.’  I intend to examine depiction of dragons from 1937  onwards to try to determine how we perceive the dragon in the modern world. To this end I will examine dragons in a variety of contemporary media, from film and television, as well as literature. They will include, but not be limited to: Game of Thrones , Eragon , The Hobbit , Dragonflight , Guards! Guards! , and How to Train Your Dragon.

Framed by adaptation studies, this thesis analyses the way in which contemporary texts re-interpret and re-imagine the dragon. In so doing, it draws on related theories, in particular human-animal studies, the uncanny, the other, and gender studies, in order to understand the enduring fascination with this mythical creature and the way in which modern authors and directors draw on and depart from both Eastern and Western mythological tradition and folklore.

The first section examines the shape of the dragon and how they are depicted, not only in literary text, but also in television, film, and art work. This involves identifying the literary and mythological forebears of these current depictions, as well as what the presentation reveals about contemporary culture. Having identified recent adaptations of the dragon’s physical form, I move to a discussion of the nature of the dragon, in particular its intelligence and morality. Throughout this section, I draw on human-animal studies to analyse the dragon’s familiarity and otherness.  

Turning to the interrelation between dragons and magic, I look at how dragons are presented as magical beings who at times exhibit magical abilities and at times are themselves the source of magic. As in my discussion of the dragon’s nature, it is the strangeness of the dragon which is apparent here: it is a creature of fantasy, beyond the realm of the rational, belonging to what J.R.R. Tolkein refers to as ‘Of Faërie’.  In the fourth chapter, the focus on dragon-slayers and dragon-riders highlights the human impulse to tame and control or destroy this mystical creature. At the same time, I reveal the human belief in their capacity to domesticate the dragon’s essential wildness to be delusive. I conclude with an analysis of the gender ambiguity of the dragon and its particular association with women, foregrounding their mutual marginalisation by society.

title: A wiggle-match date for Polynesian settlement of New Zealand

authors: Hogg, Alan G.

subjects: East Polynesia

abstract: Dating initial colonisation and environmental impacts by Polynesians in New Zealand is controversial. A key horizon is provided by the Kaharoa Tephra, deposited from an eruption of Mt Tarawera, because just underneath this layer are the first signs of forest clearance which imply human settlement. The authors used a log of celery pine from within Kaharoa deposits to derive a new precise date for the eruption via "wiggle-matching" – matching the radiocarbon dates of a sequence of samples from the log with the Southern Hemisphere calibration curve. The date obtained was 1314 ± 12 AD (2σ error), and the first environmental impacts and human occupation are argued to have occurred in the previous 50 years, i.e. in the late 13th – early 14th centuries AD. This date is contemporary with earliest settlement dates determined from archaeological sites in the New Zealand archipelago.
