The Classical Limit Of The Quantum Baker's Map, Mark Morgan-Tracy

Physics & Astronomy ETDs

This work concerns the finding of the semi-classical form of the coherent state representation for the class of quantum baker’s maps defined by Schack and Caves. It begins by introducing the finite-dimensional Hilbert space on which the quantum baker’s map is defined. Its pertinent features including the all important symmetry operators are introduced and given a full explanation. We also introduce the finite-dimensional phase space which will give the semi-classical limit a geometrical interpretation. For a D dimensional Hilbert space, the finite-dimensional phase space is found to be a grid with D2 points. Each point corresponds to a particular pair …

Fluorescence Studies In The Inductively Coupled Plasma, Anita Young

School of Geography, Earth and Environmental Sciences Theses

An Optima 3000 ICP-AES instrument was modified and the equipment necessary to carry out axial excitation atomic fluorescence was designed and constructed. Using this calibrated system, preliminary fluorescence experiments were not successful. As fluorescence is proportional to source intensity, it was considered that the excitation source, a hollow cathode lamp, may not have been sufficiently intense to produce fluorescence. A novel excitation source-driver system was designed and built in-house to operate HCLs, BDHCLs and LEDs with variable modulation frequencies and duty cycle capabilities. Studies investigating lamp response to changes in modulation frequency and duty cycle indicated that a lamp operated …

Unresolved Complex Mixtures Of Aromatic Hydrocarbons In The Marine Environment : Toxicity, Solubility And Photodegradation Studies, Emma Louise Smith

School of Geography, Earth and Environmental Sciences Theses

Unresolved complex mixtures (UCMs) of aromatic hydrocarbons have been found in a wide range of environmental matrices at high concentrations. However, limited consideration has been given to the potential detrimental effects of the accumulation of these compounds in the marine environment. In particular, there is a need to evaluate these compounds in the light of recent evidence that points to the long term effects of oil in the marine environment. The overall aim of this work was therefore to investigate unresolved complex mixtures of aromatic hydrocarbons in the marine environment with particular emphasis on assessment of toxicity, aqueous solubility and …

Barriers To Sustainability Among Tourism-Related Businesses : Identification And Reduction, Jonathan Andrew Vernon

School of Geography, Earth and Environmental Sciences Theses

The attainment of sustainable development has emerged as one of the main challenges facing society and the economy in the twenty-first century. In tourism, the English Tourism Council (2001 a, p. 11) recognise that sustainable tourism can no longer be regarded as an optional extra, but is fundamental to safeguarding the long-term competitiveness of the industry. To establish sustainable development as a primary strategic objective within the tourism industry represents a substantial challenge. Such a goal is problematic not least because the sector is so diverse and is based around a large number of small businesses which are not always …

Fundamental And Applied Measurements In Icp-Ms, Julian Robert Carter

School of Geography, Earth and Environmental Sciences Theses

Fundamental and applied aspects of ICP-MS have been investigated to gain an increased understanding of the technique and improve on its analytical capabilities. Dissociation temperatures of polyatomic ions were calculated using a double-focusing sector instrument, to obtain more reliable mass spectral data with controlled vapour introduction via a Dreschel bottle to allow accurate calculation of the ingredients in the plasma. The equilibrium temperature for the plasma, operated at 1280 W calculated using CO*, and as the thermometric probes, was c.a. 5800 - 7400 K, while using ArO* and ArC* as the thermometric probes the temperature calculated was c.a 2000 - …

Observation And Modelling Of Fluid Transport Into Porous Paper Coating Structures, Joachim Schoelkopf

School of Geography, Earth and Environmental Sciences Theses

In paper printing, one of the most important aspects for consideration is the control of ink setting rate. Ink setting, depending on ink and press type, is a function of evaporation, curing and removal of the liquid phase by capillary mechanisms steered by the porous substrate. In most cases, absorption by the substrate is the dominating mechanism. Many paper or board substrates are coated with a layer of pigment panicles and binders. It is recognised that the void network between these panicles has the most important influence on the absorption dynamics. Many aspects of liquid absorption into porous networks are …

Dealing With Complex Evidence Of Domestic Violence: A Primer For The Civil Bench, Jane C. Murphy, Jane H. Aiken

All Faculty Scholarship

New laws and policies aimed at protecting victims of domestic violence have been adopted across the country throughout the last twenty years. The legal approaches taken to protect battered women and control family violence have brought about significant changes in family law. New laws include statutes permitting civil protection or restraining orders, and laws requiring that domestic violence be considered in custody and visitation decisions. Both of these types of statutory reforms can provide protection to adult victims of domestic violence and their children. Evaluating a parent’s fitness by considering past acts of violence to other family members results in …

America’S Death Penalty: Just Another Form Of Violence, John Bessler

All Faculty Scholarship

The author in this piece reflects on the death penalty in the U.S. in the aftermath of the 9/11 terrorist attacks. The writer goes on to argue that capital punishment is, in and of itself, a form of violence. Also discussed in the article are the gradual removal of executions from public view, issues of deterrence and violent crime, and the author's preference for life-without-possibility-of-parole sentences.

Multibeam Volume Acoustic Backscatter Imagery And Reverberation Measurements In The Northeastern Gulf Of Mexico, Timoth C. Gallaudet, Christian De Moustier

Center for Coastal and Ocean Mapping

Multibeam volume acoustic backscatterimagery and reverberation measurements are derived from data collected in 200-m-deep waters in the northeastern Gulf of Mexico, with the Toroidal Volume Search Sonar (TVSS), a 68-kHz cylindrical sonar operated by the U.S. Navy’s Coastal System Station. The TVSS’s 360-degree vertical imaging plane allows simultaneous identification of multiple volume scattering sources and their discrimination from backscatter at the sea surface or the seafloor. This imaging capability is used to construct a three-dimensional representation of a pelagic fish school near the bottom. Scattering layers imaged in the mixed layer and upper thermocline are attributed to assemblages of epipelagic …

Economic Linkages Within The Rural Economy: The Case Of Producer Services, Bryan Keith Mills

Other Faculty of Science and Engineering Theses

This research seeks to contribute towards the understanding of economic linkage within the rural context by exploring the relationship between rurally located small to medium-sized enterprises (SMEs) and their purchase of producer (business) services. In addition, the work considers other inter-rural and intra-rural differences, in both firm (SME) behaviour and firm characteristics. Whilst the subject of linkages has been explored by other researchers, the market town and SME focus of this thesis provides a more spatially contained framework than is often encountered within this type of research. By using four towns of similar size and structure contained within two noticeably …

The Influence Of Extracts Of Ascophvllum Nodosum On Plant And Soil-Borne Pathogen Interactions, Felisberta Maria Jesus Cunha

Other Faculty of Science and Engineering Theses

This thesis presents an investigation into the responses to extracts of Ascophyllum nodosum (Maxicrop seaweed extracts - MSE) of two different plants species - wheat and strawberry, and their interactions with two soil-borne pathogens, Gaeumannomyces graminis and Phytophthora fragariae respectively, under various environmental conditions. The responses to MSE using hydroponic, glasshouse and field experiments showed that levels of Take-all infection in wheat were reduced by some of the treatments applied. Repeat experiments showed that consistency of results was poor but a positive trend for disease suppression followed MSE treatments. Studies of strawberry infection by Phytophthora fragariae revealed a significantly reduced …

The Role Of The Rov Within Integrated Geotechnical And Hydrographic Site Investigation, Rosemary Jayne Browning Gillon

Other Faculty of Science and Engineering Theses

The acquisition of marine survey data is traditionally undertaken from surface vessels including boats and temporary rigs. Translation of these techniques to the nearshore zone is a complex task and requires equipment adaptation and. often the sacrifice of data coverage. The remotely operated vehicle (ROV) offers the potential for overcoming some of the standard nearshore survey Concems, providing remote intervention and data acquisition in areas of restricted access. In situ testing is the most efficient and reliable method of acquiring data with minimal sediment disturbance effects. Research has been undertaken into the viability of nearshore cone penetration testing (CPT) which …

Quantification Of Marine Megafaunal Distribution Patterns Using A Remotely Operated Vehicle, David Matthew Parry

Other Faculty of Science and Engineering Theses

This thesis documents the development and application of the Automated Benthic Image Scaling System (ABISS), a novel structured lighting array for calculating image scale, accounting for perspective, to allow quantitative non-destructive megafaunal sampling using observations from a Remotely Operated Vehicle (ROV). Megafauna are important components of marine soft sediment assemblages that influence the composition of the associated assemblage and the flux of energy across the sediment-water interface, by altering the physical and chemical characteristics of the sediment during bioturbation. However, megafaunal species are not sampled adequately using traditional techniques. Megafaunal abundance estimates derived from ROV observations were validated against those …

Judicial Elections And Campaign Finance Reform, Roy A. Schotland

Georgetown Law Faculty Publications and Other Works

In the judicial realm, the issue of campaign finance cuts across all states that use any form of election as part of their selection or retention system, whether the elections are partisan or non-partisan. The raising of money for campaigns is a task that has to be performed in all states that use any form of election. Like many other things that we have discussed today it seems to involve a sort of balancing act. The state certainly has a strong interest in protecting the integrity of its judiciary and encouraging the public perception of the judiciary as an institution …

To improve cardiac care services, there is an urgent need of developing early diagnosis of heart diseases and optimal intervention strategies. As such, it calls upon a better understanding of the pathology of heart diseases.

Computer simulation and modeling have been widely applied to overcome many practical and ethical limitations in in-vivo, ex-vivo, and whole-animal experiments. Computer experiments provide physiologists and cardiologists an indispensable tool to characterize, model and analyze cardiac function both in healthy and in diseased heart. Most importantly, simulation modeling empowers the …

Acridine Orange For Malaria Diagnosis: Its Diagnostic Performance, Its Promotion And Implementation In Tanzania, And The Implications For Malaria Control, J. Keiser, J. Utzinger, Zul Premji, Y. Yamagata, B.H. Singer

Pathology, East Africa

One hundred years ago, Giemsa's stain was employed for the first time for malaria diagnosis. Giemsa staining continues to be the method of choice in most malarious countries, although, in the recent past, several alternatives have been developed that exhibit some advantages. Considerable progress has been made with fluorescent dyes, particularly with Acridine Orange (AO). The literature on the discovery, development and validation of the AO method for malaria diagnosis is reviewed here. Compared with conventional Giemsa staining, AO shows a good diagnostic performance, with sensitivities of 81.3%-100% and specificities of 86.4%-100%. However, sensitivities decrease with lower parasite densities, and …

Micro-Affordances In Visual Mental Imagery And Visual Short-Term Memory, Noreen Derbyshire

School of Psychology Theses

Micro-affordance effects have been reported for several different components of the reachto- grasp action during on-line visual processing (Tucker and Ellis, 1998; Ellis and Tucker, 2000; and Tucker and Ellis, 2001). One property of these effects is that they have been shown to terminate once an object is removed from view (Tucker and Ellis, 2001). This thesis describes eight experiments that examine the presence of micro-affordance effects during off-line visual processing. All eight experiments employ a stimulus-response compatibility paradigm. Three different experimental designs were employed to examine the presence of micro-affordance effects arising from the relationship between: (a) the power …

Stereotypes In The Language Of Beauty Product Advertisements, J.R. Shanmugam

Student Works (2000-2009)

This study focuses on the connotative language used in printed facial and slimming advertisements, which may be adhering to any common stereotypes of tile ideal Malaysian beauty in terms of complexion and figure or body weight. It was found that beauty product advertisements do convey a stereotypical beauty to the potential consumer. This so-called ideal beauty has a fair and youthful-looking complexion and a slim figure However, this stereotypical beauty is only implied subtly through the advertisement The research methodology has been carried out in 4 stages Stage 1 consisted of mere extraction of words from the advertisements Stage 2 …

These teachers believe there are better teaching methods to use in physical education. The purpose of this paper is to analyze the background, application, strengths and weaknesses of the TGFU model. This paper will specifically analyze whether the TGFU model is an effective way to teach students motor skills, knowledge and to make decisions during game play.

Vocabulary : A Building Block In Reading, Lisa L. Capper

Graduate Research Papers

From all of my reading and research, I learned that vocabulary is an essential part of teaching. In all of the curriculum areas, knowledge of vocabulary is important. With word understanding, comprehension grows and so does the student's knowledge.

Vocabulary development activities not only include many opportunities for students to be actively involved with reading a variety of books, but, through vocabulary instruction, the teacher directly teaches important words and strategies to help students understand what they are reading. Through the use of a variety of strategies I observed how different strategies can help students learn and grow in their …
