Formalizing A Conceptual Framework Of Work Domain Knowledge, Min Zhu

Dissertations and Theses (Open Access)

Background: The failure rate of health information systems is high, partially due to fragmented, incomplete, or incorrect identification and description of specific and critical domain requirements. In order to systematically transform the requirements of work into real information system, an explicit conceptual framework is essential to summarize the work requirements and guide system design. Recently, Butler, Zhang, and colleagues proposed a conceptual framework called Work Domain Ontology (WDO) to formally represent users’ work. This WDO approach has been successfully demonstrated in a real world design project on aircraft scheduling. However, as a top level conceptual framework, this WDO has not …

Detecting Electron Motion In Atoms And Molecules, Hua-Chieh Shao, Anthony F. Starace

Anthony F. Starace Publications

The detection of spatial and temporal electronic motion by scattering of subfemtosecond pulses of 10 keV electrons from coherent superpositions of electronic states of both H and T⁺₂ is investigated. For the H atom, we predict changes in the diffraction images that reflect the time-dependent effective radius of the electronic charge density. For an aligned T⁺₂ molecule, the diffraction image changes reflect the time-dependent localization or delocalization of the electronic charge density.

Crystalline Order On Catenoidal Capillary Bridges, Mark Bowick, Zhenwei Yao

Physics - All Scholarship

We study the defect structure of crystalline particle arrays on negative Gaussian curvature capillary bridges with vanishing mean curvature (catenoids). The threshold aspect ratio for the appearance of isolated disclinations is found and the optimal positions for dislocations determined. We also discuss the transition from isolated disclinations to scars as particle number and aspect ratio are varied.

Theatre Of The Arts: Caribbean Intertextuality And The Muse Of Place, Lara B. Cahill-Booth

Open Access Dissertations

Theatre of the Arts: Caribbean Intertextuality and the Muse of Place is a literary geography that explores how specific environments shape imaginative interventions into history and language. I begin by examining the unity of Derek Walcott's vision of the sea, tracing its ties to oral history, literary canon, and personal reveries of emplacement in Omeros and other epic-minded poems. I follow the sea to its continental origins, examining the Guyanas, an Amazonian bioregion on the borderlands of Guyana, Brazil, and Venezuela, as a place imaginatively remapped by twentieth-century novelists Alejo Carpentier, Wilson Harris, Mario de Andrade, and Pauline Melville. I …

A Comparative Analysis Of Changes In Postural Control Following Training Using The Wii Balance Program And Standardized Falls Prevention Programs, Alessandra Pluchino

Open Access Dissertations

Declines in balance and postural control are believed to be the major neuromuscular factors that contribute to an increased risk of falling with age. Balance training has been reported to be an effective tool for increasing these parameters in older fallers, but its effectiveness in improving balance in higher-functioning, independent-living elders is uncertain. PURPOSE: The purpose of this study was to compare the impact of two formal balance-training interventions (Tai Chi and standardize balance exercise program [SBEP]) and an activity-promoting video game, the Wii Fit balance program. METHODS: Twenty-nine healthy, independent seniors (72.10 ± 7.80) were randomly assigned to eight …

Extraction Of Contact Resistance In Carbon Nanofiber Via Interconnects With Varying Lengths, Ken Li, Patrick Wilhite, Vinit Khera, Shoba Krishnan, Xuhui Sun, Cary Y. Yang

Electrical and Computer Engineering

A method to extract the contact resistance and bulk resistivity of vertically grown carbon nanofibers (CNFs) or similar one-dimensional nanostructures is described. Using a silicon-compatible process to fabricate a terrace test structure needed for the CNF length variation, the contact resistance is extracted by measuring in situ the resistances of individual CNFs with different lengths and within a small range of diameters using a nanoprober inside a scanning electron microscope. Accurate determination of contact resistances for various combinations of catalysts and underlayer metals can lead to eventual optimization of materials’ growth and device fabrication processes for CNF via interconnects.

Metastable Anions Of Dinitrobenzene: Resonances For Electron Attachment And Kinetic Energy Release, A. Mauracher, S. Denifl, A. Edtbauer, M. Hager, M. Probst, Olof E. Echt, T. D. Maerk, P. Scheier, T. A. Field, K. Graupner

Physics & Astronomy

Attachment of free, low-energy electrons to dinitrobenzene (DNB) in the gas phase leads to DNB as well as several fragment anions. DNB, (DNB-H), (DNB-NO), (DNB-2NO), and (DNB-NO(2)) are found to undergo metastable (unimolecular) dissociation. A rich pattern of resonances in the yield of these metastable reactions versus electron energy is observed; some resonances are highly isomer-specific. Most metastable reactions are accompanied by large average kinetic energy releases (KER) that range from 0.5 to 1.32 eV, typical of complex rearrangement reactions, but (1,3-DNB-H)(-) features a resonance with a KER of only 0.06 eV for loss of NO. (1,3-DNB-NO)(-) offers a rare …

The Stream–Lake Ecotone: Potential Habitat For Juvenile Endangered June Suckers (Chasmistes Liorus), Russell B. Rader, Mark C. Belk, Rollin Hotchkiss, Jaron Brown

Western North American Naturalist

Potamodromous fish are poorly studied even though they are threatened often by human activities. The June sucker (Chasmistes liorus) is an endangered potamodromous species endemic to Utah Lake. Larval June suckers have not been collected from Utah Lake for at least 3 decades. Recruitment appears to be limited by low temperatures and scarce food, resulting in mass starvation of larval June suckers in the stream environment. We compared water temperature, zooplankton food availability, and small fish abundance in the stream and in 3 habitats along the stream–lake ecotone (dense emergent vegetation, sparse emergent vegetation, and open lake) to …

Retrospective Evaluation Of The Effects Of Human Disturbance And Goldfish Introduction On Endangered Pahrump Poolfish, James E. Deacon, Joshua E. Williams

Western North American Naturalist

Life history data for Pahrump poolfish (Empetrichthys latos latos) collected from 1937 to 1975 were organized and analyzed to improve our understanding of changes caused by human habitat disruption and introduced goldfish (Carassius auratus) at Manse Spring, Nevada. Pahrump poolfish twice demonstrated their ability to recover numerically from a population crash. The first crash followed a November 1961 introduction of a few goldfish and subsequent removal of vegetation by local ranch children intent on turning Manse Spring into a swimming hole. The second crash followed another major habitat disturbance resulting from an unsuccessful attempt to eradicate …

Diversity, Phenology, And Elevational Distribution Of Ephemeroptera, Plecoptera, And Trichoptera In American Fork Canyon, Utah, Sarah Walker Judson, C. Riley Nelson

Western North American Naturalist

Although the aquatic insect fauna of Utah and their associated adult forms are well documented taxonomically and biogeographically, little is known about seasonal and elevational patterns of aquatic insect diversity in individual Wasatch streams. We selected the American Fork River, a relatively pristine stream with little anthropogenic disturbance, as our target stream to investigate elevational distribution and seasonal phenology of adult forms of Ephemeroptera, Plecoptera, and Trichoptera (EPT). From April to October in 2003 through 2005, a total of 71 adult forms of EPT species were documented along the American Fork River. No single sampling period captured more than 30 …

Pathology Of An Unusual Lumbar Condition In A Young Black Bear (Ursus Americanus) From The Big Bend Region Of Trans-Pecos Texas, Frederick B. Stangl Jr., Dana R. Mills, Michael W. Haiduk

Western North American Naturalist

The skeleton of a young American black bear (Ursus americanus) possessing asymmetrical distortions of the 5 caudalmost lumbar neural spines was recovered from west Texas. We attribute this abnormality, presumed to be congenital, to the absence or atrophy of the right multifidus muscle straddling L3 and to the series of compensatory muscle adjustments required to maintain spinal alignment. This finding may have important management implications for black bears in Texas, given the possibility that our specimen originates from a partially isolated population.

Pitch Angle Scattering In The Outer Heliosheath And Formation Of The Interstellar Boundary Explorer Ribbon, Konstantin V. Gamayunov, Ming Zhang, Hamid K. Rassoul

Aerospace, Physics, and Space Science Faculty Publications

The dominant and unexpected feature in the first Interstellar Boundary EXplorer (IBEX) maps is a ribbon of the enhanced energetic neutral atom (ENA) emissions. Presenting the first results from IBEX,McComas et al. identified six possible mechanisms of ribbon formation. One of the mechanisms, the so-called secondary ENA mechanism, was already quantitatively elaborated by Heerikhuisen et al., and they successfully reproduced the main features of the ribbon. We further study the "secondary ENA" mechanism by quantifying a previously omitted stage of the proton evolution between two consecutive acts of the charge-exchange in the outer heliosheath (OHS). The main findings can be …

The Kepler Light Curve Of V344 Lyrae: Constraining The Thermal-Viscous Limit Cycle Instability, John K. Cannizzo, Martin D. Still, Steve B. Howell, Matt A. Wood, Alan P. Smale

Aerospace, Physics, and Space Science Faculty Publications

We present time-dependent modeling based on the accretion disk limit cycle model for a 270 d light curve of the short-period SU UMa-type dwarf nova V344 Lyr taken by Kepler. The unprecedented precision and cadence (1 minute) far surpass that generally available for long-term light curves. The data encompass two superoutbursts and 17 normal (i.e., short) outbursts. The main decay of the superoutbursts is nearly perfectly exponential, decaying at a rate ~12 d mag−1, while the much more rapid decays of the normal outbursts exhibit a faster-than-exponential shape. Our modeling using the basic accretion disk limit cycle can produce the …

Precision Frequency Measurements With Interferometric Weak Values, David J. Starling, P. Ben Dixon, Andrew N. Jordan, John C. Howell

Mathematics, Physics, and Computer Science Faculty Articles and Research

We demonstrate an experiment which utilizes a Sagnac interferometer to measure a change in optical frequency of 129 ± 7 kHz/√Hz with only 2 mW of continuous-wave, single-mode input power. We describe the measurement of a weak value and show how even higher-frequency sensitivities may be obtained over a bandwidth of several nanometers. This technique has many possible applications, such as precision relative frequency measurements and laser locking without the use of atomic lines.

A Preliminary Assessment Of The Long-Term Prospects For Offshore Wind Farms In Maltese Territorial Waters, Dane Orion Zammit

Masters Theses, 2010-2019

Almost all of Malta’s current interest in offshore wind development is focused on the development of an offshore wind farm at Sikka L-Bajda in northwest Malta by 2020, to help the country reach its mandated 2020 RES target. The offshore wind industry is rapidly gaining momentum, with larger projects in deeper waters further offshore being commissioned every year. Countries like Germany and the United Kingdom have actively constructed, or are planning to construct, offshore wind farms at transitional water depths before 2020. The offshore wind energy market has historically been restricted to the North Sea, the Baltic Sea and the …
