Improved Accuracy For Fluid Flow Problems Via Enhanced Physics, Michael Case May 2010

Improved Accuracy For Fluid Flow Problems Via Enhanced Physics, Michael Case

All Dissertations

This thesis is an investigation of numerical methods for approximating solutions to fluid flow problems, specifically the Navier-Stokes equations (NSE) and magnetohydrodynamic equations (MHD), with an overriding theme of enforcing more physical behavior in discrete solutions. It is well documented that numerical methods with more physical accuracy exhibit better long-time behavior than comparable methods that enforce less physics in their solutions. This work develops, analyzes and tests finite element methods that better enforce mass conservation in discrete velocity solutions to the NSE and MHD, helicity conservation for NSE, cross-helicity conservation in MHD, and magnetic field incompressibility in MHD.

Reduction Of Rocket-Borne Atmospheric Density Measurements Using Monte Carlo Simulation, Travis Gaulden

All Theses

The HEX II atmospheric rocket experiment, conducted near 9:30 U.T. February 14, 2007 from the Poker Flat Rocket Range in Alaska was designed to lead to a better understanding of density and velocity gradients in the lower thermosphere. In a supporting role to this mission, cold cathode ionization gauges recorded composite density along three rocket payload trajectory paths from 90 km to 200 km. Rocket-borne instruments experience near sonic to hypersonic velocities and encounter a range of viscous, slipflow, and collisionless flow conditions at these heights. These variable conditions necessitate the use of tailored analytic expressions appropriate to the flow …

Structural Assessment Of The Effects Of Amino Acid Substitutions On Protein Stability And Protein-Protein Interaction, Shaolei Teng, Liangjiang Wang, Anand K. Srivastava, Charles E. Schwartz, Emil Alexov Mar 2010

Structural Assessment Of The Effects Of Amino Acid Substitutions On Protein Stability And Protein-Protein Interaction, Shaolei Teng, Liangjiang Wang, Anand K. Srivastava, Charles E. Schwartz, Emil Alexov

Publications

A structure-based approach is described for predicting the effects of amino acid substitutions on protein function. Structures were predicted using a homology modelling method. Folding and binding energy differences between wild-type and mutant structures were computed to quantitatively assess the effects of amino acid substitutions on protein stability and protein–protein interaction, respectively. We demonstrated that pathogenic mutations at the interaction interface could affect binding energy and destabilise protein complex, whereas mutations at the non-interface might reduce folding energy and destabilise monomer structure. The results suggest that the structure-based analysis can provide useful information for understanding the molecular mechanisms of diseases.

A Solution-Based Approach To The Fabrication Of Novel Chalcogenide Glass Materials And Structures, Nathan Carlie Mar 2010

A Solution-Based Approach To The Fabrication Of Novel Chalcogenide Glass Materials And Structures, Nathan Carlie

All Dissertations

Chalcogenide glasses (ChGs) are well known for their large optical nonlinearities and high infrared transparency, and are candidate materials for next-generation thin film-based planar infrared (IR) optical applications. They are also known, however, to possess low thermal and mechanical stability as compared to oxide glasses. Traditional physical vapor deposition (PVD) methods used for the deposition of these materials as thin films often suffer from low deposition rates, deviation from stoichiometry, and cannot coat over complex surfaces. In order to retain the attractive optical properties of ChGs while enabling new fabrication routes and hybrid and composite material systems, we have developed …

Empirical Modeling Of The Stress-Strain Relationship For An Upsetting Process Under Direct Electrical Current, Joshua Jones, Laine Mears, J. T. Roth

Publications

Present research involving Electrically-Assisted Manufacturing (EAM) has shown the advantageous effects that an applied current flux provides on the mechanical properties with respect to part formation. Overall general results using this process include the reduction of the flow stress during forming, increased achievable deformation, and a decrease or elimination of springback. Specifically targeting the compression process, this paper evaluates the stress-strain relationship and develops from experimental results an initial stress predictor function that includes the effect of electrical current. Once developed, the derived empirical model is shown capable of estimating the flow stress for an EAM upsetting test at various …

Gamma-rays at MeV energies provide a unique window on the high energy Universe, especially so for nuclear astrophysics. The potential for significant contributions, e.g., to the understanding of SNe Ia as well as the large potential for new discoveries has long been recognized, but technical progress in this challenging energy band has been slow. The groundbreaking discoveries of CGRO’s COMPTEL, however, have inspired and driven the development of powerful new instrumentation over the past decade. Novel detector technologies developed in the US and Japan enable compact Compton telescopes, greatly improving the efficiency and field-of-view achievable with this technique successfully employed …

Over the next decade, we can expect time domain astronomy to flourish at optical and radio wavelengths. In parallel with these efforts, a dedicated transient "machine" operating at higher energies (X-ray band through soft gamma-rays) is required to reveal the unique subset of events with variable emission predominantly visible above 100 eV. Here we focus on the transient phase space never yet sampled due to the lack of a sensitive, wide-field and triggering facility dedicated exclusively to catching high energy transients and enabling rapid coordinated multi-wavelength follow-up. We first describe the advancements in our understanding of known X-ray transients that …

On The Origin Of The Highest Redshift Gamma-Ray Bursts, Krzysztof Belczynski, Daniel E. Holz, Chris L. Fryer, Edo Berger, Dieter H. Hartmann, Brain O'Shea

Publications

GRB 080913 and GRB 090423 are the most distant gamma-ray bursts (GRBs) known to date, with spectroscop-ically determined redshifts of z = 6.7 and z = 8.1, respectively. The detection of bursts at this early epoch of the universe significantly constrains the nature of GRBs and their progenitors. We perform population synthesis studies of the formation and evolution of early stars, and calculate the resulting formation rates of short- and long-duration GRBs at high redshift. The peak of the GRB rate from Population II stars occurs at z ∼ 7for a model with efficient/fast mixing of metals, while it is …

Unrooted Stem Cutting Physiology; Water Use And Leaf Gas Exchange Of Severed Stem Cuttings, Peter Alem Jan 2010

Unrooted Stem Cutting Physiology; Water Use And Leaf Gas Exchange Of Severed Stem Cuttings, Peter Alem

All Theses

Stem cuttings are one of the most frequently used and successful methods of vegetative plant propagation. The understanding of unrooted cutting physiology, especially gas exchange and water flux, is crucial for successful propagation of healthy plants. Prior to root initiation, water uptake is limited and leafy stem cuttings are most vulnerable to wilting.
Experiments were carried out in the greenhouse with poinsettia cuttings to determine water uptake, photosynthesis, transpiration and stomatal conductance from the time of severing to rooting, including time spent in storage. Water uptake through the severed stem was investigated in the laboratory and growth chamber. Cutting gas …
