Improved Constrained Global Optimization For Estimating Molecular Structure From Atomic Distances, Terri Marie Grant Jan 2008

Improved Constrained Global Optimization For Estimating Molecular Structure From Atomic Distances, Terri Marie Grant

Mathematics & Statistics Theses & Dissertations

Determination of molecular structure is commonly posed as a nonlinear optimization problem. The objective functions rely on a vast amount of structural data. As a result, the objective functions are most often nonconvex, nonsmooth, and possess many local minima. Furthermore, introduction of additional structural data into the objective function creates barriers in finding the global minimum, causes additional computational issues associated with evaluating the function, and makes physical constraint enforcement intractable. To combat the computational problems associated with standard nonlinear optimization formulations, Williams et al. (2001) proposed an atom-based optimization, referred to as GNOMAD, which complements a simple interatomic distance …

Subcellular Localization Of Human T-Cell Leukemia Virus Type 1 Tax Oncoprotein, Kimberly Anne Fryrear Jan 2008

Subcellular Localization Of Human T-Cell Leukemia Virus Type 1 Tax Oncoprotein, Kimberly Anne Fryrear

Theses and Dissertations in Biomedical Sciences

Human T-cell Leukemia Virus Type 1 (HTLV-1) is a transforming retrovirus that gives rise to Adult T-cell Leukemia (ATL) and a variety of other subneoplastic conditions such as HTLV-Associated Myelopathy/Tropical Spastic Paraperesis (HAM/TSP). In ATL, the transformation and immortalization of T-lymphocytes has been attributed to the expression and activity of a single HTLV-1 viral protein, namely the trans-activating protein Tax. Although the exact mechanism of Tax-mediated transformation is uncertain, current studies support a model in which Tax induces genomic instability in the host cell through interference with DNA repair mechanisms, dysregulation of cell cycle progression, transcriptional activation of cellular …

Academic Success: A Qualitative Case Study Of Student Perspectives, Heather Marie Bentley Jan 2008

Academic Success: A Qualitative Case Study Of Student Perspectives, Heather Marie Bentley

Dissertations and Theses @ UNI

Over the past eight years of teaching high school, I have noticed more and more high school students seem to be apathetic about their school work and academic success. I wanted to explore why students appeared to care less about their academic success. After consulting the literature, I realized the student voice was missing from most of the current studies; therefore, I wanted my qualitative study to focus on student views. In order to do so, I created two surveys: one for students and another for teachers, and I also interviewed a small sample of students after completion of the …

Specification And Automatic Code Generation Of The Data Layer For Data-Intensive Web-Based Applications, Sergei Golitsinski Jan 2008

Specification And Automatic Code Generation Of The Data Layer For Data-Intensive Web-Based Applications, Sergei Golitsinski

Dissertations and Theses @ UNI

In this thesis I propose a new code generation approach to developing data-intensive web-based applications. I hypothesize that it is possible to build a code generator which will significantly improve development of data-intensive web-based applications by generating at least 50% of the data access code based on a specification of the application's data model. My main argument is that the application's data model is sufficient for deriving most of the data access functionality. To test this hypothesis I designed a data definition language, came up with a set of rules for deriving data access operations from the application's data model, …

Hypersonic Boundary Layer Receptivity To Acoustic Disturbances Over Cones, Kursat Kara Jan 2008

Hypersonic Boundary Layer Receptivity To Acoustic Disturbances Over Cones, Kursat Kara

Mechanical & Aerospace Engineering Theses & Dissertations

The receptivity mechanisms of hypersonic boundary layers to free stream acoustic disturbances are studied using both linear stability theory (LST) and direct numerical simulations (DNS). A computational code is developed for numerical simulation of steady and unsteady hypersonic flow over cones by combining a fifth-order weighted essentially non-oscillatory (WENO) scheme with third-order total-variation-diminishing (TVD) Runge-Kutta method. Hypersonic boundary layer receptivity to free-stream acoustic disturbances in slow and fast modes over 5-degree, half-angle blunt cones and wedges are numerically investigated. The free-stream Mach number is 6.0, and the unit Reynolds number is 7.8×106/ft. Both the steady and unsteady solutions are obtained …

Experimental Investigation Of Active Control Of Bluff Body Vortex Shedding, Ilteris Koc Jan 2008

Experimental Investigation Of Active Control Of Bluff Body Vortex Shedding, Ilteris Koc

Mechanical & Aerospace Engineering Theses & Dissertations

Mean and fluctuating forces acting on a body are strongly related to vortex shedding generated behind it. Therefore, it is possible to obtain substantial reductions of at least the unsteady forces if vortex shedding is controlled or its regularity is reduced. While conventional active flow control methods are mainly concerned with direct interaction with, and alteration of, the mean flow about a body, modern techniques involve altering existing flow instabilities using relatively small inputs to obtain large-scale changes of mean flows. Aerodynamic flow control may be intended to delay or suppress boundary layer separation through creation of a boundary layer …

"Stand And Unfold Yourself": The Subjectivity Of Interpretation In Hamlet, Josh Mahoney Jan 2008

"Stand And Unfold Yourself": The Subjectivity Of Interpretation In Hamlet, Josh Mahoney

Student Writing Awards

Critical interpretations of Hamlet are largely dependent upon the cultural zeitgeist that provides the cognitive paradigm through which critics formulate their ideas. The zeitgeist also influences which text of Hamlet to consider, since no single authoritative manuscript of the play exists. Critics must also consider Hamlet beyond a simple textual reading, since the competing documents of Q1, Q2 and F1—among later additions—only serve as the basis for theatrical representations. The inherent fluidity of performance is apparent to anyone who has ever been to the theater, even a modern one. Actors embodying characters on stage in front of an audience make …
