The chemical oxygen-iodine laser (COIL) has several important military and industrial applications. The concern of this work is do develop a partial differential equation model describing optical behavior in the COIL. Optical behavior of the COIL has traditionally been investigated via a ray tracing method. Photons are represented as discrete particles, and their behavior is described by the geometry of the system. We develop an optical model wherein photons have a wave description. In order to construct the mathematical model, we utilize the theory of paraxial wave optics and Gaussian beams. Doing so allows us to incorporate physical effects such as diffusion/diffraction and refraction into the model. After describing the optical model, we present numerical methods for obtaining approximate solutions to the model in the cases of one and two transverse directions. Results are presented illustrating the efficacy of the numerical methods. / Ph. D.

This thesis seeks to examine the nineteenth-century art collections and architectural style of the original buildings at the University of Sydney in order to demonstrate ways in which visual material may be employed to shape public perception of an institution. I shall argue that the architectural style of the original university buildings was specifically chosen with particular aims which extended beyond the mere establishment of a tertiary institution for the colony. I will also argue that the style shaped the character of the institution, contributed to the maintenance of law and order in the colony, linked the colony more firmly than hitherto to the mother country and provided social benefits for the founders of the institution. The instant history and character thus imposed upon the institution was reinforced by the assembly of a portrait collection in emulation of other collections of portraits at leading institutions of the colony and the mother country, including the Oxbridge universities. Once the building proclaimed that the institution was comparable with the great universities of the world, the subjects of the portraits at the university could be placed in the class of founders of a great historical institution, thus at the same time enhancing the reputation of the institution and the individuals. The construction of an indentity through visual images was extended by the benefactions of Sir Charles Nicholson, the principal donor of works of art to the university in the nineteenth century. I argue that his intentions in relation to his collections were didactic but were also concerned with the entrenchment of the imperial hegemony over the colony, and again with the enhancement of his personal repuatation. This analysis shows how, by a complex of personal ambition and aspiration for the colony, the style of the buildings and the art collections formed were used to establish the colony as civilized and the new university as a bastion of English tradition.

During 1984 I carried out an Internship in Materials Conservation under the supervision of Mrs. Patricia Johnson, the Conservator of the Nicholson Museum of Antiquities, the University of Sydney. My area of specialization was in the conservation of artifacts. The majority of artifacts examined and treated during the Internship were from archaeological excavations in the Middle East, at the site of Pella, in Jordan. The site of Pella has produced artifacts from a wide chronological range ; Neolithic, Bronze Age, Iron Age, Hellenistic (Greek), Roman, and Arabic historical periods. A selection of these artifacts has been granted to the University of Sydney by the Jordanian government, and constitute the present Pella Collection. Most of the materials are inorganic, i.e. ceramics, metals, glass, and stone, although bone and ivory artifacts, as well as skeletal material, form a part of the collection. Upon an initial examination of the collection, conservation problems were identified and a program of conservation work for the collection was formulated. Priority treatment was given to the metals in the collection, particularly to the small bronzes which were found to be suffering from "bronze disease" (active corrosion), to ceramics needed for study and display, and to glass with unstable surfaces. Improvements in storage conditions for the Pella Collection, particularly in the packing of small finds and the storage of metals, were also given a high priority. Taken altogether, the Pella Collection has proved to be a wellbalanced collection, covering almost every period of Kiddle Eastern Archaeology, and containing artifacts representative of most types of materials and of ancient technology. Planned as a research and teaching collection for the students of the Department of Archaeology, the University of Sydney, it also proved to be an excellent teaching collection for a student of materials conservation. The following, therefore, is a report on my Internship in Archaeological Conservation, and includes a description of the institution which sponsored the Internship, a description of both the program of work and the program of instruction for the Internship, detailed descriptions of all conservation work and other activities which were undertaken as part of the: Internship, and a final evaluation of the Internship.

Esta pesquisa analisa a história dos modelos atômicos no início do século XX a partir das contribuições de Joseph John Thomson, Hantaro Nagaoka, Ernest Rutherford, John William Nicholson e Niels Bohr e seus contemporâneos, enfatizando as explicações desde a Física Clássica até a introdução da Teoria Quântica. A tese apresenta uma introdução e oito capítulos. O primeiro capítulo procura dar conta do “estado da arte” antes da proposição dos modelos discutidos. Neste capítulo enfatizamos questões que se localizam no campo da ciência clássica, sem mergulhar no campo da teoria quântica nascente. Na continuidade, apresentamos seis capítulos, cronologicamente organizados com uma breve biografia de cada um dos cientistas mencionados e o detalhamento das idéias e dos episódios científicos que levaram às publicações que apresentaram seus modelos pela primeira vez. A publicação dos modelos de átomo quantizados teve grande impacto e suscitou muitos debates, o que nos levou a produzir o capítulo sete tratando especificamente desses embates. Para concluir no capítulo oito apresentamos algumas considerações sobre a integração das diversas trilhas investigativas que levam à publicação dos modelos atômicos discutidos; ao trabalho nas fronteiras de campos investigativos diversos; à intrincada dinâmica de poder entre campos, cientistas e publicações; e à afirmação de novos campos. / The present research examines the history of atomic models in the early twentieth century dealing with the contributions of Joseph John Thomson, Hantaro Nagaoka, Ernest Rutherford, John William Nicholson and Niels Bohr and his contemporaries. It emphasizes the explanations from the classical physics till the introduction of the Quantum Theory. This thesis presents an introduction and eight chapters. Chapter 1 presents the investigations which took place before the proposition of the models pointed out in the first paragraph. This chapter emphasizes the classical science, without diving into the quantum explanations. The next six chapters present a chronological sequence of biographies, ideas and publications and discuss the atomic models proposed by the quoted scientists. The publication of the papers on the quantized atom models had great impact and caused many debates, which led us to produce a specific chapter dealing with such subject. . In conclusion, the chapter eight presents some considerations about the integration of the investigative trails that led to the publication of the atomic models discussed, the work on investigative borders fields, the intricate dynamics of power between fields, scientists and publications, and the assertion of new fields.
