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.

Identification and Characterization of LYSMD3, A Novel Epithelial Cell Pattern Recognition Receptor for Chitin
(Virginia Tech, 2019-10-14)LysM-domain containing (LysMD) proteins are widespread in nature and associated with host-pathogen interactions, often-binding peptidoglycan and chitin. However, the functions of mammalian LysMD proteins have not been fully ... -
Competition, Cost Analytics, and Offsetting Strategies: Pressures and Opportunities on the Fraud Triangle
(Virginia Tech, 2021-04-05)This study introduces industry competition factors to fraud models to examine how competition associates with fraud risk. I argue that industry competition eclipses many firm-level determinants in their association with ... -
Radar and LiDAR Fusion for Scaled Vehicle Sensing
(Virginia Tech, 2021-04-02)Scaled test-beds (STBs) are popular tools to develop and physically test algorithms for advanced driving systems, but often lack automotive-grade radars in their sensor suites. To overcome resolution issues when using a ... -
Designing outdoor spaces to support older adult dog walkers: A multi-method approach to identify and prioritize features in the built environment
