ETDs: Virginia Tech Electronic Theses and Dissertations
Browse by
Virginia Tech has been a world leader in electronic theses and dissertation initiatives for more than 20 years. On January 1, 1997, Virginia Tech was the first university to require electronic submission of theses and dissertations (ETDs). Ever since then, Virginia Tech graduate students have been able to prepare, submit, review, and publish their theses and dissertations online and to append digital media such as images, data, audio, and video.
University Libraries staff are currently digitizing thousands of pre-1997 theses and dissertations and loading them into VTechWorks. Most of these theses and dissertations are fully available to the public, but we will, in general, honor requests by the item's author to restrict access to Virginia Tech only. See our process for Requesting that Material be Amended or Removed.
To search all Virginia Tech print and digital theses and dissertations, use the University Libraries ETD resource guide.
Materials that are restricted to Virginia Tech only may be requested via your own university or public library's Interlibrary Loan program or through the VTechWorks request form that appears when you try to access the item. You might also be able to obtain a copy of the work through ProQuest's database of theses and dissertations. If you are on a Virginia Tech campus but are unable to find the pre-1997 thesis or dissertation you are seeking in VTechWorks, you may also be able to order a physical copy from library storage. Please check the library catalog at http://www.lib.vt.edu/ for physical copies.
The guidelines that apply to Virginia Tech's graduate students as ETD authors can be found at http://guides.lib.vt.edu/ETDguide.

Integrating Laser Scanning with Discrete Element Modeling for Improving Safety in Underground Stone Mines
(Virginia Tech, 2019-05-10)According to the Mine Health and Safety Administration (MSHA), between 2006 and 2016, the underground stone mining industry had the highest fatality rate in 4 out of 10 years, compared to any other type of mining in the ... -
Limited Revisionism and Error Theory
(Virginia Tech, 2019-06-25)In Joyce's Myth of Morality, Joyce proposes an error theory about morality. He then argues that, once we accept an error theory, we have three options: we can be abolitionists and jettison moral discourse, be conservationists ... -
Regioselective, Nucleophilic Activation of C-F Bonds in o-Fluoroanilines
(Virginia Tech, 2019-06-25)Reactions of fluorinated anilines with stoichiometric Ti(NMe2)4 in mesitylene (typically for 23 h at 120 °C) afforded moderate to high yields of the corresponding N,N-dimethyl-o-phenylenediamine derivatives resulting from ... -
On the Intelligibility of Grounding Autonomy
(Virginia Tech, 2019-06-25)Metaphysical grounding has received a great deal of attention in the metaphysics literature within the last decade, offering what many see as an attractive theoretical alternative to other attempts to analyze the nature ... -
Computer Vision Tracking of sUAS From a Pan/Tilt Platform
(Virginia Tech, 2019-06-24)The ability to quickly, accurately, and autonomously identify and track objects in digital images in real-time has been an area of investigation for quite some time. Research in this area falls under the broader category ... -
Evaluating the quality of ground surfaces generated from Terrestrial Laser Scanning (TLS) data
(Virginia Tech, 2019-06-24)Researchers and GIS analysts have used Aerial Laser Scanning (ALS) data to generate Digital Terrain Models (DTM) since the 1990s, and various algorithms developed for ground point extraction have been proposed based on the ... -
Bending and warpage of elastic plates
(Virginia Tech, 2019-06-24)This thesis presents two studies on elastic plates. In the first study, we discuss the choice of elastic energies for thin plates and shells, an unsettled issue with consequences for much recent modeling of soft matter. ... -
Enhancing Fault Localization with Cost Awareness
(Virginia Tech, 2019-06-24)Debugging is a challenging and time-consuming process in software life-cycle. The focus of the thesis is to improve the accuracy of existing fault localization (FL) techniques. We experimented with several source code line ... -
Advanced Characterization of Materials for Superconducting Radiofrequency Accelerator Cavities
(Virginia Tech, 2019-06-24)Particle accelerators are a leading tool for frontier science. Pushing that frontier further demands more machines with higher performance, and more of a very expensive technology: superconducting radio-frequency (SRF) ... -
On the Number of Representations of One as the Sum of Unit Fractions
(Virginia Tech, 2019-06-24)The Egyptian Fractions of One problem (EFO), asks the following question: Given a positive integer n, how many ways can 1 be expressed as the sum of n non-increasing unit fractions? In this paper, we verify a result ... -
Strontium in Drinking Water: Assessing Strontium as a Drinking Water Contaminant in Virginia Private Wells
(Virginia Tech, 2019-06-24)Approximately 80% of Virginians with private drinking water (PDW) sources are unaware of the quality of their drinking water. Strontium is a water quality contaminant gaining recognition at the federal level. At concentrations ... -
