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.

Efficient Algorithms for Data Analytics in Geophysical Imaging
(Virginia Tech, 2021-06-14)Modern sensing systems such as distributed acoustic sensing (DAS) can produce massive quantities of geophysical data, often in remote locations. This presents significant challenges with regards to data storage and performing ... -
Isogeometric Approach to Optical Tomography
(Virginia Tech, 2021-06-14)Optical Tomography is an imaging modality that enhances early diagnosis of disease through use of harmless Near-Infrared rays instead of conventional x-rays. The subsequent images are used to reconstruct the object. However ... -
Optimization Methods for Dynamic Mode Decomposition of Nonlinear Partial Differential Equations
(Virginia Tech, 2021-06-14)Reduced-order models have long been used to understand the behavior of nonlinear partial differential equations. Naturally, reduced-order modeling techniques come at the price of either computational accuracy or computation ... -
Numerical Analysis and Parameter Optimization of Portable Oscillating-Body Wave Energy Converters
(Virginia Tech, 2021-06-14)As a clean, abundant, and renewable source of energy with a strategic location in close proximity to global population regions, ocean wave energy shows major promise. Although much wave energy converter development has ... -
A Novel Method and Two Exoskeletons for Whole-arm Gravity Compensation
(Virginia Tech, 2021-06-14)This thesis is centered upon the published A Novel Method and Exoskeletons for Whole-arm Gravity Compensation (Turner, Hull 2020), and includes a novel concept for supporting the weight of a person's arm or robotic linkage. ... -
One For All: A Capitol Proposal
(Virginia Tech, 2021-06-14)June 26, 2020 marked the passing of H.R.51 through the House of Representatives, a historic moment in the long fight for DC's statehood. This fight is not merely anchored by an argument about taxation without representation; ... -
Depictions of Donation: A Thematic Analysis of Organ Donation Storylines in Television Medical Dramas
(Virginia Tech, 2021-06-14)With a global and national shortage in the number of registered organ donors, this study employed a qualitative thematic analysis of thirteen episodes from popular medical dramas that aired between 2016-2020. The aim of ... -
PRADA-TF: Privacy-Diversity-Aware Online Team Formation
(Virginia Tech, 2021-06-14)In this work, we propose a PRivAcy-Diversity-Aware Team Formation framework, namely PRADA-TF, that can be deployed based on the trust relationships between users in online social networks (OSNs). Our proposed PRADA-TF is ... -
How Well Can Two-Wave Models Recover the Three-Wave Second Order Latent Model Parameters?
(Virginia Tech, 2021-06-14)Although previous studies on structural equation modeling (SEM) have indicated that the second-order latent growth model (SOLGM) is a more appropriate approach to longitudinal intervention effects, its application still ... -
Spiking Neural Network with Memristive Based Computing-In-Memory Circuits and Architecture
(Virginia Tech, 2021)In recent years neuromorphic computing systems have achieved a lot of success due to its ability to process data much faster and using much less power compared to traditional Von Neumann computing architectures. There are ... -
Computing the trace of an endomorphism of a supersingular elliptic curve
(Virginia Tech, 2021-06-10)We provide an explicit algorithm for computing the trace of an endomorphism of an elliptic curve which is given by a chain of small-degree isogenies. We analyze its complexity, determining that if the length of the chain, ... -
