Inclusive photoproduction of D*± mesons has been measured for photon-proton centre-of-mass energies in the range 130 < W < 28OGeV and photon virtuality Q2 < IGeV2. The data sample used corresponds to an integrated luminosity of 37 pb-1. Total and differential cross sections as functions of the D* transverse momentum and pseudorapidity are presented in restricted kinematical regions and the data are compared with next-to-leading order (NLO) perturbative QCD calculations using the "massive charm" and "massless charm" schemes. The measured cross sections are generally above the NLO calculations, in particular in the forward (proton) direction. The large data sample also allows the study of dijet production associated with charm. A significant resolved as well as a direct photon component contribute to the cross section. Leading order QCD Monte Carlo calculations indicate that the resolved contribution arises from a significant charm component in the photon. A massive charm NLO parton level calculation yields lower cross sections compared to the measured results in a kinematic region where the resolved photon contribution is significant.

Physical And Technical Bases Of Using Ferromagnetic Resonance In Hexagonal Ferrites For Electromagnetic Compatibility Problems, Marina Koledintseva, Alexander A. Kitaytsev Jan 1999

Physical And Technical Bases Of Using Ferromagnetic Resonance In Hexagonal Ferrites For Electromagnetic Compatibility Problems, Marina Koledintseva, Alexander A. Kitaytsev

Electrical and Computer Engineering Faculty Research & Creative Works

Frequency-selective measurement of microwave signal parameters based on application of gyromagnetic converters has proven advantageous for the research of microwave radiation over a wide spectrum (several octaves) in multisignal regime in microwave path and for the solution of a number of electromagnetic compatibility (EMC) problems. The measurement frequency band can be enlarged to millimeter-waves with application of monocrystal hexagonal ferrite resonators (HFR) having high internal magnetic fields. Millimeter-wave field interactions with the HFR having alternating resonance frequency are analyzed. This is useful for millimeter-wave signal modulation and demodulation. The analysis is based on the solution of magnetization vector motion equation …

Electrical and Computer Engineering Faculty Research & Creative Works

This paper investigates integrating power engineering material over the breadth of an electrical engineering curriculum. Electrical engineering curricula have a large number of required courses and many subareas for students to study. By introducing power concepts in a variety of courses, students may be motivated to take additional courses in the power area and are better prepared for the diverse background which will be required of them as practising power engineers. The important interrelationships between subareas of electrical engineering are better understood by students when cross discipline applications are discussed. This paper describes the introduction of power concepts and applications …

Nonlinear Constrained Optimizer And Parallel Processing For Golden Block Line Search, Duc T. Nguyen, Wilson H. Tang, Yeou K. Tung, Hakizumwami B. Runesha Jan 1999

Nonlinear Constrained Optimizer And Parallel Processing For Golden Block Line Search, Duc T. Nguyen, Wilson H. Tang, Yeou K. Tung, Hakizumwami B. Runesha

Civil & Environmental Engineering Faculty Publications

Generalized exponential penalty functions are constructed for the multiplier methods in solving nonlinear programming problems. The non-smooth extreme constraint Gext is replaced by a single smooth constraint Gs by using the generalized exponential function (base a>1). The well-known K.S. function is found to be a special case of our proposed formulation. Parallel processing for Golden block line search algorithm is then summarized, which can also be integrated into our formulation. Both small and large-scale nonlinear programming problems (up to 2000 variables and 2000 nonlinear constraints) have been solved to validate the proposed algorithms.

Guarding The Gate To The Courthouse: How Trial Judges Are Using Their Evidentiary Screening Role To Remake Tort Causation Rules, Lucinda M. Finley Jan 1999

Guarding The Gate To The Courthouse: How Trial Judges Are Using Their Evidentiary Screening Role To Remake Tort Causation Rules, Lucinda M. Finley

Journal Articles

The article looks at what trial judges are actually doing in toxic tort cases in the post-Daubert world; it reviews and critiques cases in which judges have in effect adopted a new rule of causation law that requires plaintiffs to rely on epidemiology, and in particular epidemiology that demonostrates an increase in relative risk of 2.0 or greater; the article considers the substantive as well as the normative implications of this legal treatment of epidemiology.

Parental Rights And The Ugly Duckling, Margaret F. Brinig, F. H. Buckley Jan 1999

Parental Rights And The Ugly Duckling, Margaret F. Brinig, F. H. Buckley

Journal Articles

Hans Christian Andersen's "The Ugly Duckling" is best remembered for its moral, "To be born in a duck's nest, in a farmyard, is of no consequence to a bird, if it is hatched from a swan's egg." Having read and thought about this story many times, we should like to suggest another, less heart-warming, interpretation. The story of the Ugly Duckling, that most resilient of cygnets, masks the tragedy of children who suffer abuse. Its message, that personal spirit will triumph when a child grows up, misrepresents the experience of many victimized children. If we wait for the child to …

Perceptions Of Web Site Design Characteristics: A Malaysian/Australian Comparison, R. Laupase Jan 1999

Perceptions Of Web Site Design Characteristics: A Malaysian/Australian Comparison, R. Laupase

Theses: Doctorates and Masters

The study compared the perceptions of Malaysians, representing Asian culture, and Australians, representing Western culture, for four Web design characteristics (atmospherics, news stories, signs, products and services), as part of the Integrated Internet Marketing model. Under controlled laboratory conditions, two groupings of thirty subjects evaluated eight Web sites in the retail and services sectors located equally in Malaysia and Australia. This study hypothesised that the predominant culture would not be generalised to another culture. Significant differences found for Web design characteristics were typically for one site only and not across all sites. In other words, consistent differences did not eventuate. …

Analysis Of Increases In Fishing Power In The Western Rock Lobster (Panulirus Cygnus) Fishery, John Fernandez Jan 1999

Analysis Of Increases In Fishing Power In The Western Rock Lobster (Panulirus Cygnus) Fishery, John Fernandez

Theses: Doctorates and Masters

The western rock lobster, Panulirus cygnus, fishery represents a significant commercial asset to Western Australia, and it is therefore important that appropriate strategies are developed to effectively manage it. Because the fishery has a very high level of exploitation, researchers and managers rely significantly on annual stock assessments which are based on catch and effort data. This study will identify and assess the effects that changes in fishing power factors (e.g. advances in fish-finding technology) have had on estimates of catch and effort. The fishing power increases can be used to adjust nominal fishing effort to produce a time series …

Man Makes Man : A Study Of Uplifting And Upbuilding In The Novels Of Joseph Furphy, Raymond Driehuis Jan 1999

Man Makes Man : A Study Of Uplifting And Upbuilding In The Novels Of Joseph Furphy, Raymond Driehuis

Theses: Doctorates and Masters

In a letter to Kate Baker, circa November 1910, Furphy wrote, '[b]ut ain't it anomalous that the erratic G.H [Grant Hervey], the saintly Dr. Strong, and the perverse T.C. [Tom Collins] should be working strenuously toward the same goal, namely, the uplifting and upbuildlng of Australia' (In Barnes and Hoffmann, eds, 1995:259. My Italics). This thesis is an Investigation of the ideas of uplifting and upbuildlng, and their relevance to Tom Collins and his concerns. The reason for Furphy waiting so long to lay bare his designs can only be speculated. Rather than accepting the general critical stance that Collins …

Confrontation And Identity In The Fiction Of J.M. Coetzee, Dawn Grieve Jan 1999

Confrontation And Identity In The Fiction Of J.M. Coetzee, Dawn Grieve

Theses: Doctorates and Masters

This thesis is an examination of the fictional works of J.M. Coetzee to date. By focusing my gaze upon either the lack of encounter or the encounters between the 'Self' and the 'Other', I explore the relationship between confrontation and the fluid formation and erosion of identity. This exploration takes place against a dual background: the history of the apartheid government in South Africa, the legacy of oppression and the post-apartheid opportunities and challenges; and Coetzee's own acknowledgement of complicity with the past and commitment to a reconciled future. This study not only examines a broad range of criticism on …

A Phenomenological Study Of Clinical Decision Making By Flight Nurse Specialists In Emergency Situations, Dale M. Pugh Jan 1999

A Phenomenological Study Of Clinical Decision Making By Flight Nurse Specialists In Emergency Situations, Dale M. Pugh

Theses: Doctorates and Masters

Clinical decision making is an integral, multifaceted phenomenon fundamental to nursing practice. The domain of flight nursing practice is unique in terms of knowledge, structure, clinical presentations and environment. The uniqueness and diversity of patient scenarios and the advanced practice level of the flight nurse role blend to provide a potential rollercoaster flight mission. At the time this research was conducted nursing standards to guide clinical decision making were being developed. Medically orientated clinical guidelines were in place, but they were designed to highlight a specific, well defined clinical scenario or skill. It has been argued that guidelines for nursing …

Capital Investment Decisions Of Large Industrial Firms In Major European Countries, Faith Yilmaz Jan 1999

Capital Investment Decisions Of Large Industrial Firms In Major European Countries, Faith Yilmaz

Plymouth Business School Theses

Using large-company panel data, this thesis empirically analyses investment decisions in major European countries. We particularly concentrate on three issues: the taxation of capital in the EU, the role of agency costs of debt on investment decisions, and the empirical analyses of the investment-uncertainty relationship. First, based on a dynamic system in capital and Tobin's q ratio, some simplified analytical results are derived to simulate various tax policy effects on investment. Also, for a single investment project, a model is developed to consider jointly the role of uncertainty and irreversibility in the taxation of capital. The simulation results cast doubt …
