ASU Electronic Theses and Dissertations


This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.

In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.

Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries.

This thesis examines the modeling, analysis, and control system design issues for scramjet powered hypersonic vehicles. A nonlinear three degrees of freedom longitudinal model which includes aero-propulsion-elasticity effects was used for all analysis. This model is based upon classical compressible flow and Euler-Bernouli structural concepts. Higher fidelity computational fluid dynamics and finite elementmethods are needed formore precise intermediate and final evaluations. The methods presented within this thesis were shown to be useful for guiding initial control relevant design. The model was used to examine the vehicles static and dynamic characteristics over the vehicles trimmable region. The vehicle has significant longitudinal …

Contemporary theories of trauma identify the creation of a coherent trauma narrative and therapeutic exposure to trauma memories as potential recovery mechanisms. These factors are often inherent to the disclosure process, resulting in a parallel theoretical framework for experimental research that conceptualizes disclosure as a therapeutic intervention. The present investigation examined the moderational impact of disclosure following trauma on the link between trauma severity and symptoms of Posttraumatic Stress Disorder (PTSD). Disclosure status (discloser or nondiscloser), highest extent of disclosure, and length of delay to first disclosure were tested in a series of moderated regression models among a sample of …

Telomerase is a special reverse transcriptase that extends the linear chromosome termini in eukaryotes. Telomerase is also a unique ribonucleoprotein complex which is composed of the protein component called Telomerase Reverse Transcriptase (TERT) and a telomerase RNA component (TR). The enzyme from most vertebrate species is able to utilize a short template sequence within TR to synthesize a long stretch of telomeric DNA, an ability termed "repeat addition processivity". By using human telomerase reconstituted both in vitro (Rabbit Reticulocyte Lysate) and in vivo (293FT cells), I have demonstrated that a conserved motif in the reverse transcriptase domain of the telomerase …
