Application Of Automotive Engine Control Technology To General Aviation Aircraft Powerplants., Christopher John Tennant Jan 1997

Application Of Automotive Engine Control Technology To General Aviation Aircraft Powerplants., Christopher John Tennant

Graduate Theses, Dissertations, and Problem Reports (ETD)

The general aviation industry has lagged behind the automotive industry in powerplant development due to depressed economic conditions in their marketplace. Recent efforts to revitalize the industry have encountered the hindrance of thirty-year-old engine technology. Current automotive engine control technology has been reviewed for its potential for transfer to existing general aviation powerplants. Current automotive engine control technology was classified into basic, correction, and feedback elements for the control of fuel flow and ignition timing. The value of each element was assessed for application to a general aviation powerplant in terms of an aviation duty cycle. An extensive database produced …

Patenting Medical Procedures: A Search For A Compromise Between Ethics And Economics, Beata Gocyk-Farber Jan 1997

Patenting Medical Procedures: A Search For A Compromise Between Ethics And Economics, Beata Gocyk-Farber

Cardozo Law Review

When doctor Samuel Pallin, an Arizona ophthalmologist, brought an infringement suit for his patent covering the "stitchless" incision in cataract surgery, he probably did not expect that he would provoke one of the most emotional patent debates in history. Physicians across the country expressed condemnation of medical process patents, calling such patents "horrendous" and warning that Dr. Pallin's victory may have "profoundly devastating and mind-boggling consequences" for medical science. The resonance in the medical community was so strong that the American Medical Association House of Delegates passed a resolution "vigorously" condemning the patenting of medical and surgical procedures and promising …

Faster Ray Tracing Using Adaptive Grids, Thomas W. Sederberg, Krysztof S. Klimaszewski Jan 1997

Faster Ray Tracing Using Adaptive Grids, Thomas W. Sederberg, Krysztof S. Klimaszewski

Faculty Publications

A new hybrid approach is presented which outperforms the regular grid technique in scenes with highly irregular object distributions by a factor of hundreds, and combined with an area interpolator, by a factor of thousands. Much has been said about scene independence of different acceleration techniques and the alleged superiority of one approach over another. Several theoretical and practical studies conducted in the past have led to the same conclusion: a space partitioning method that allows the fastest rendering of one scene often fails with another. Specialization may be the answer. This has always been pursued, consciously or not, in …

On The Dynamic Behaviour Of A Thermoviscoelastic Body In Frictional Contact With A Rigid Obstacle, Kenneth Kuttler, K. T. Andrews, M. Shillor Jan 1997

On The Dynamic Behaviour Of A Thermoviscoelastic Body In Frictional Contact With A Rigid Obstacle, Kenneth Kuttler, K. T. Andrews, M. Shillor

Faculty Publications

We consider the dynamic behaviour of a thermoviscoelastic body which may come into frictional contact with a rigid obstacle. The frictional contact is modelled by general contact and friction laws which include as special cases the power law normal compliance condition and the corresponding generalization of Coulomb's law of dry friction. The stress-strain constitutive relation is assumed to be of Kelvin-Voigt type and the frictional heat generation on the contact surface is taken into account. In this setting we establish the existence of a solution to a weak version of the energy-elasticity system which consists of a parabolic equation coupled …

An Assessment Of The Prevalence Of Trichomonas Sp. In The Domestic Pigeon (Columba Livia) Population, In The Emirates Of Abu Dhabi And Dubai, Theresa Caroline Bailey

Theses

A survey of 250 captive (animal market) and free-flying (trapped at a sheep farm) pigeons was conducted to assess the prevalence of Trichomonas sp. in the domestic pigeon (Columba livia) population, in the United Arab Emirates (UAE). Oropharyngeal swabs demonstrated that 52% of all pigeons were found with Trichomonas sp. in their oropharynx, of which 60%, 68% and 35% of pigeons were Trichomonas sp. positive in the AI Ain and Abu Dhabi animal markets and AI Ain sheep farm respectively. Captive birds had a significantly higher infection rate than the free-flying pigeons. Inspection of the oropharynx of live pigeons positive …

Solvent Impregnated Resins For The Recovery Of Gold From Gold(I)Thiourea Solutions, Fiona Fitzpatrick Jan 1997

Solvent Impregnated Resins For The Recovery Of Gold From Gold(I)Thiourea Solutions, Fiona Fitzpatrick

Masters

Solvent Impregnated Resins (SIRs) are high surface area, macroporous, polymeric resins which have been physically impregnated with an organic solvent. In this research, three resins have been impregnated with Di-2-ethylhexyl phosphoric acid, a solvent which has shown selectivity to gold. The ability of the resins to recover gold (1) thiourea perchlorate from solution has been investigated. The resins have been studied both bare and when impregnated with the solvent and their efficiency was seen to increase upon impregnation. The overall efficiency of the resins was found to be pH dependent. It is also related to the level of impregnation of …

Chemistry Faculty Research & Creative Works

CD40 is a molecule present on multiple cell types including B lymphocyte lineage cells. CD40 has been shown to play an important role in B cell differentiation and activation in vitro, although little is known concerning the effects of CD40 stimulation in vivo. We therefore examined the effects of CD40 stimulation in mice using a syngeneic bone marrow transplantation (BMT) model in an effort to augment B cell recovery after high dose therapy with hematopoietic reconstitution. After the BMT, mice were treated with or without 2-6 μg of a soluble recombinant murine CD40 ligand (srmCD40L) given intraperitoneally twice a week. …

Romanticizing Leadership: A Historical And Cultural Critique, Elisa Maureen Sandra Carlson Edd Jan 1997

Romanticizing Leadership: A Historical And Cultural Critique, Elisa Maureen Sandra Carlson Edd

Dissertations

Romanticism, a cultural and intellectual ideology of the late 18th and early 19th century, left a historical legacy of ecstasy and disaster upon subsequent generations. Manifestations of neo-romanticism are evident in many areas of contemporary culture. These modern manifestations, which include an infusion of the spiritual into everyday life, pantheistic adoration of nature, glorification of the self, fascination with the irrational, focus on the power of the imagination, subjugation of the individual to the common good, and apocalyptic hope for a new world, are influencing, theories and practices of leadership. This research set out to find out whether leadership studies …

Testability Properties Of Divergent Trees, Ronald D. Blanton, John P. Hayes Jan 1997

Testability Properties Of Divergent Trees, Ronald D. Blanton, John P. Hayes

University Faculty Publications and Creative Works

The testability of a class of regular circuits called divergent trees is investigated under a functional fault model. Divergent trees include such practical circuits as decoders and demultiplexers. We prove that uncontrolled divergent trees are testable with a fixed number of test patterns (C-testable) if and only if the module function is surjective. Testable controlled trees are also surjective but require sensitizing vectors for error propagation. We derive the conditions for testing controlled divergent trees with a test set whose size is proportional to the number of levels p found in the tree (L-testability). By viewing a tree as overlapping …

Intensive Supervised Probation And Institutional Placements For Adjudicated Youth: A Closer Look., Cleaster Marie Jackson Jan 1997

Intensive Supervised Probation And Institutional Placements For Adjudicated Youth: A Closer Look., Cleaster Marie Jackson

Graduate Theses, Dissertations, and Problem Reports (ETD)

With the alarming rate of school violence and teen crime public outcry demands that we look for immediate remedies to make schools and communities safe. One solution which has received public support is the current trend to solve this problem by building more juvenile facilities to house these youth. This short term fix, which has been referred to as an "out of sight out of mind mentality" creates other concerns such as loss of educational dollars to public schools and highlights the lack of commitment to provide effective programs to meet the needs of challenging students. The purpose of this …

The Influence Of Decision Aids On User Behavior: Implications For Knowledge Acquisition And Inappropriate Reliance, Steven M. Glover, Douglas F. Prawitt, Brian C. Spilker Jan 1997

The Influence Of Decision Aids On User Behavior: Implications For Knowledge Acquisition And Inappropriate Reliance, Steven M. Glover, Douglas F. Prawitt, Brian C. Spilker

Faculty Publications

Structured decision aids are widely used in many organizational settings, and their influence on judgment consistency and accuracy have received considerable attention in the literature. While two benefits commonly associated with decision aid use are improved judgment and enhanced expertise development, relatively little attention has been directed toward the potential influence of decision aids on decision maker behavior. In particular, we argue that the use of structured aids may influence relatively inexperienced decision makers to approach aided tasks mechanistically, without becoming actively involved in the task or judgment. Such passive decision behavior may, in some situations, threaten gains in performance …

Gas Mass Fractions And The Evolution Of Spiral Galaxies, Stacy S. Mcgaugh Jan 1997

Gas Mass Fractions And The Evolution Of Spiral Galaxies, Stacy S. Mcgaugh

Faculty Scholarship

We show that the gas mass fraction of spiral galaxies is strongly correlated with luminosity and surface brightness. It is not correlated with linear size. Gas fraction varies with luminosity and surface brightness at the same rate, indicating evolution at fixed size. Dim galaxies are clearly less evolved than bright ones, having consumed only ∼1/2 of their gas. This resolves the gas consumption paradox, since there exist many galaxies with large gas reservoirs. These gas-rich galaxies must have formed the bulk of their stellar populations in the last half of a Hubble time. The existence of such immature galaxies at …

Particle Mixing By The Polychaete Capitella Species 1: Coupling Fate And Effect Of A Particle-Bound Organic Contaminant (Fluoranthene) In A Marine Sediment, Susanne D. Madsen, Thomas L. Forbes, Valery E. Forbes Jan 1997

Particle Mixing By The Polychaete Capitella Species 1: Coupling Fate And Effect Of A Particle-Bound Organic Contaminant (Fluoranthene) In A Marine Sediment, Susanne D. Madsen, Thomas L. Forbes, Valery E. Forbes

Valery Forbes Publications

Particle mixing by the polychaete Capitella sp. 1 was investigated in a 22 d microcosm experiment in the presence and absence of the sediment-bound polycyclic aromatic hydrocarbon (PAH) fluoranthene. Mixing by Capitella sp. 1 (30000 ind. m–2) was examined using glass bead tracers (diam. = 30 to 100 μm) with and without a pulse introduction of fluoranthene to the sediment surface. Worms had a profound effect on the sediment appearance and reworked sediment in a conveyor-belt fashion. The predominant mode of mixing was bioadvective, and the worms created a subsurface maximum in the glass bead tracer profiles. Glass …
