Active Regulation Of Speed During A Simulated Low-Altitude Flight Task: Altitude Matters!, April M. Bennett

Browse all Theses and Dissertations

This study examined active regulation of speed during a low-altitude flight task as a function of global optical flow rate, speed, and the presence or absence of a concurrent altitude disturbance. The results showed that altitude clearly had an impact on speed control; specifically, control of speed was much more difficult when altitude disturbances were present. Even in the no altitude disturbance conditions, performance tended to be best at lower altitudes. Consistent with previous research, the results suggest that speed and altitude changes have additive effects on speed judgments. This is inconsistent with the simple global optical flow rate hypothesis …

Topology Optimization Of Engine Exhaust-Washed Structures, Mark A. Haney

Browse all Theses and Dissertations

Aircraft structure subjected to elevated temperature and acoustic loading present a challenging design environment. Thermal stress in a structural component has typically been alleviated by allowing thermal expansion. However, very little work has been done which directly addresses the situation where such a prescription is not possible. When a structural component has failed due to thermally-induced tensile stresses, the answer to the question of how best to stiffen the structure is far from trivial. In this work, we demonstrate that conventional stiffening techniques, for example, those which add material to the thickness of a failing panel, may actually increase the …

Multi-Attribute Optimization Based On Conjoint Analysis, Hemanth K. Amarchinta

Browse all Theses and Dissertations

Over the last thirty years, there were tremendous advances in multidisciplinary design optimization in reducing computational cost, developing algorithms for efficient sensitivity analysis in reaching an optimum. Most of these efforts assumed a single objective (attribute) function and a multitude of constraints. Very little work has been done in including the designer's preferences as part of the optimization scheme and in addressing the ability to handle multiple attributes simultaneously. This need to develop a systematic method for including designer's preferences is the main focus of this research work. The concept of modeling preferences among multi-attribute alternatives is prevalent in consumer …

Using In-Situ Error Tracking For Mode Selection In Proper Orthogonal Decomposition Reduced Order Modelling, Michael Richard Maddux

Browse all Theses and Dissertations

Proper Orthogonal Decomposition (POD) provides a method of analyzing data and/or creating a Reduced Order Model (ROM). In this thesis, POD is used to create a ROM comprised of basis functions onto which the governing equations of a Computational Fluid Dynamics (CFD) problem are projected via Galerkin's method. The model is of reduced order since the basis functions span a space smaller than the space from which they were created. A full order simulation called the training period is conducted first to obtain data to be used for creating the ROM using POD. The dominant characteristics are extracted from the …

The Modeling Of Solubility, Frank Christopher Campanell

Browse all Theses and Dissertations

In this work the solubilities of gases in liquids and liquids in liquids were modeled using both physical properties and topological descriptors of the solutes. Quantitative structure-activity relationship (QSAR) methods were employed to create single-linear regression (SLR) and multiple-linear regression (MLR) models of the solubilities. Factor analysis was employed to determine the number of significant factors present in the solubilities. The solubilities of monoalcohols in water, halogenated alkanes in water, gases in water, gases in alkanes, and gases in alcohols were examined and modeled.

System Analysis And Rf-Floodlight Exploitation Of Short-Range Gotcha Repeaters, Jose A. Montes De Oca

Browse all Theses and Dissertations

Emerging wide-area synthetic aperture radar (SAR) system concepts call for a single data collection platform to orbit a large ( e.g., 20-km) spot at a nominal range of 40-km. The large standoff distance and desire for fine resolution, coupled with a need for persistent real-time sensing, pose a significant challenge in terms of clutter-to-noise ratio (CNR) performance and data processing. Increased CNR and reduced processing load can be achieved by decreasing the range of the SAR system and the size of the area of interest. Employing multiple cooperating SAR systems allows the same overall coverage area to be maintained …

Interactive Effects Of Feedback Type And Feedback Propensities On Task Performance, Kristin M. Delgado

Browse all Theses and Dissertations

The purpose of the present study was to examine the effects of feedback types (i.e., outcome, process, and task feedback), feedback propensities, and their interactions on task performance in an attempt to determine, first, which types of feedback produced better task performance and, second, how feedback propensities influenced relationships between feedback type and performance. Process feedback and task feedback were expected to interact in their effects on task performance. In addition, I predicted that external feedback propensity would moderate the effects of process feedback on performance and initial task performance would moderate the effects of internal feedback propensity on task …

Classical And Quantum Algorithms For Finding Cycles, Jill Cirasella

Publications and Research

Quantum computing—so weird, so wonderful—inspires much speculation about the line between the possible and the impossible. (Of course, there is still unclarity about how “impossible” intractable problems are and about how “possible” quantum computers are.) This thesis takes a slightly different tack: instead of focusing on how to make the impossible possible, it focuses on how to make the possible easier.

More specifically, this paper discusses quantum algorithms for finding cycles in graphs, a problem for which polynomial-time classical algorithms already exist. It explains and compares the classical and quantum algorithms, and it introduces a few new algorithms and observations. …

Diatom Paleolimnological Record Of Holocene Climatic And Environmental Change In The Altai Mountains, Siberia, Karlyn S. Westover, Sherilyn C. Fritz, Tatyana A. Blyakharchuk, Herbert E. Wright

Department of Earth and Atmospheric Sciences: Faculty Publications

The sedimentary diatom records of three shallow lakes in the Altai Mountains, southern Siberia, were examined to assess the nature and timing of Holocene environmental changes. Few paleoenvironmental records, especially reconstructions not based on pollen, have been reported from this region. The lakes differ in elevation, annual precipitation, and catchment vegetation. Diatom assemblages in all lakes were dominated for the entire period of record by small benthic species of Pseudostaurosira Williams & Round, Staurosira Ehrenberg, and Staurosirella Williams & Round. Planktonic taxa only occur in very low abundances (<5%). The most diverse diatom flora was found in Dzhangyskol, which is situated at the lowest elevation within a forested catchment. A lack of detailed information on the ecological preferences of the dominant taxa and the complexity of environmental drivers make direct interpretation of the diatom record difficult. However, other proxies suggest that dramatic shifts in dominance between Staurosira elliptica and Staurosirella pinnata in Grusha Ozero reflect millennial-scale variability …

Moisture-Induced Delayed Spallation And Interfacial Hydrogen Embrittlement Of Alumina Scales, James L. Smialek Ph.D.

United States National Aeronautics and Space Administration: Publications

While interfacial sulfur is the primary chemical factor affecting Al₂O₃ scale adhesion, moisture-induced delayed spallation appears as a secondary, but impressive, mechanistic detail. Similarities with bulk metallic phenomena suggest that hydrogen embrittlement from ambient humidity, resulting from the reaction Al_alloy +3(H₂O)_air = Al(OH)–3 +3H⁺ may be the operative mechanism. This proposal was tested on pre-oxidized René N5 by standard cathodic hydrogen charging in 1N H₂SO₄, as monitored by weight change, induced current, and microstructure. Cathodic polarization at –2.0 V abruptly stripped mature Al₂O₃ scales at …

Thomas Aquinas And The Metaphysics Of Law, William S. Brewbaker Iii

Articles

Despite modernity's longstanding aversion to metaphysics, legal scholars are increasingly questioning whether law can be understood in isolation from wider questions about the nature of reality. This Article examines perhaps the most famous of metaphysical legal texts—Thomas Aquinas's still widely read Treatise on Law—with a view toward tracing the influence of Thomas's metaphysical presuppositions. This Article shows that Thomas's account of human law cannot be fully understood apart from his metaphysics. Attention to Thomas's hierarchical view of reality exposes tensions between Thomas's “top-down” account of law and his sophisticated “bottom-up” observations. For example, Thomas grounds human law's authority in its …

Sausage-Making, Pigs' Ears, And Congressional Expansions Of Federal Jurisdiction: Exxon Mobil V. Allapattah And Its Lessons For The Class Action Fairness Act, Adam N. Steinman

Articles

The year 2005 witnessed two watershed developments in federal jurisdiction: the U.S. Supreme Court's decision in Exxon Mobil Corp. v. Allapattah Services, Inc. and the enactment of the Class Action Fairness Act (CAFA). Allapantah and CAFA raise the same fundamental question: how should courts interpret a statute whose text would expand federal jurisdiction far beyond what Congress apparently intended? In Allapattah, the Court confronted this question in resolving an aspect of the supplemental jurisdiction statute that had deeply divided both the judiciary and academia. CAFA's expansion of federal jurisdiction over class actions will require courts to struggle with this question …

Understanding sexual harassment as a form of discrimination because of sex has grown increasingly difficult as our understandings of both gender and sex have grown richer and more complex This piece offers a new descriptive model for understanding gender bias in the context of sexual harassment law The piece argues that two separate sets of ideas about gender have intersected to produce a new picture of gender equality one that is separated from a binary model of men and women but that nonetheless continues to disadvantage women as compared to men The paper refers to this idea as the androcentricassimilation …

Developing A More Holistic Approach To Water Management In The United States, William L. Andreen

Articles

Americans have generally treated water just like land and other natural resources as a commodity for human use manipulation and degradation Little thought or significance at least until relatively recently was attached to the adverse environmental impact of reduced stream flows and the damage caused by hydrologic modifications such as dams and by various development activities that disrupt and pollute aquatic habitats The United States therefore faces the difficult challenge of trying at a late date to bring together three separate but inextricably connected disciplines one focusing on water use one on water quality and yet another focusing on development …

Assessing, Modifying, And Combining Data Fields From The Virginia Office Of The Chief Medical Examiner (Ocme) Dataset And The Virginia Department Of Forensic Science (Dfs) Datasets In Order To Compare Concentrations Of Selected Drugs, Amy Elizabeth Herrin

Theses and Dissertations

The Medical Examiner of Virginia (ME) dataset and the Virginia Department of Forensic Science Driving Under the Influence of Drugs (DUI) datasets were used to determine whether people have the potential to develop tolerances to diphenhydramine, cocaine, oxycodone, hydrocodone, methadone, and morphine. These datasets included the years 2000-2004 and were used to compare the concentrations of these six drugs between people who died from a drug-related cause of death (of the drug of interest) and people who were pulled over for driving under the influence. Three drug pattern groups were created to divide each of the six drug-specific datasets in …

Undone, Julie J. Johnson

Theses and Dissertations

My art has become rooted in a process of layering. I layer materials to explore technique and to express the concept of inside versus outside. The evidence of multiple layers of materials is symbolically connected to what is happening within my own life. I want the viewer to see an indication of deeper layers of process and materials rather than just the polished surface of an artwork. This layering process can also be seen as a metaphor for human nature, what we see on the outside is not always what is on the inside.

Memory-Craft: The Role Of Domestic Technology In Women's Journals, Tammy Powley

Electronic Theses and Dissertations

The term "memory-craft" refers to arts and crafts media where personal memorabilia and journaling are combined and assembled into book form. Examples of memory-crafts include scrapbooks, art journals, and altered books. Traditionally, women have been the primary assemblers of memory-crafts, using this form as a method of autobiography and genealogical archiving. Memory-crafting is often associated with the amateur home-crafter, and while historians have long understood its cultural significance, academia has not properly considered memory-craft as a type of alternative discourse. The purpose of this study is to examine the use of memory-crafting as a non-traditional method of writing, especially among …

Lab Testing And Field Implementation Of Soil Flushing, Linda S. Lee, Xihong Zhai, Jaesun Lee

JTRP Technical Reports

Many of the Indiana Department of Transportation (INDOT) sites are contaminated with aromatic hydrocarbons and chlorinated solvents; these contaminants often occur in the form of light non-aqueous phase liquids (LNAPLs) or dense non-aqueous phase liquids (DNAPLs). Considerable effort has recently been focused on developing in-situ technologies for removing or destroying NAPL source zones, and several potentially viable methods have emerged including cosolvent-enhanced source zone removal. Most recently, site-specific remedial designs involving a combination of in-situ methods (often referred to as a treatment train) have been proposed for which data are still sparse. The primary goal of the laboratory experiments is …
