Spatial Resolution of Equatorial Plasma Depletions Using Variable-Range Time-Delay Integration
(Virginia Tech, 2019-06-17)Previous plasma imaging missions have used time-delay integration techniques that correct for uniform motion blur during integration. This was due to the assumed constant range-to-target of each pixel in the observed scene. ... -
Deactivation Diagram Development for Naval Ship System Vulnerability Analysis
(Virginia Tech, 2019-06-17)System architecture analyses of distributed ship systems offer a practical view of system behavior over all operational states; however, the effectiveness of these analyses can be bound by limited computational performance ... -
CandyFactory: Cloud-Based Educational Game for Teaching Fractions
(Virginia Tech, 2019-06-17)Nowadays cross platform software development is more expensive than ever before in terms of time and effort. Meantime with increasing number of personal devices, it is harder for local applications to synchronize and connect ... -
Securitization and Refugee Resettlement Policy: Using Social Media to Understand Public Attitudes
(Virginia Tech, 2019-06-17)This thesis answers the question of how public opinion toward refugees and asylum-seekers expressed in opinion polls compares with that expressed through commentary on news articles posted by Cable News Network (CNN) on ... -
Study of Sensing Issues in Dynamic Spectrum Access
(Virginia Tech, 2019-06-14)Dynamic Spectrum Access (DSA) is now a commonly used spectrum sharing paradigm to mitigate the spectrum shortage problem. DSA technology allows unlicensed secondary users to access the unused frequency bands without ... -
Analyzing and Classifying Neural Dynamics from Intracranial Electroencephalography Signals in Brain-Computer Interface Applications
(Virginia Tech, 2019-06-14)Brain-Computer Interfaces (BCIs) that rely on motor imagery currently allow subjects to control quad-copters, robotic arms, and computer cursors. Recent advancements have been made possible because of breakthroughs in ... -
Deep Learning Neural Network-based Sinogram Interpolation for Sparse-View CT Reconstruction
(Virginia Tech, 2019-06-14)Computed Tomography (CT) finds applications across domains like medical diagnosis, security screening, and scientific research. In medical imaging, CT allows physicians to diagnose injuries and disease more quickly and ... -
Effect of Postmortem Time and Preservation Fluid on the Tensile Material Properties of Bovine Liver Parenchyma
(Virginia Tech, 2017-12-21)The liver is one of the most frequently injured abdominal organs in motor vehicle collisions. Although previous studies have quantified the tensile failure properties of human liver parenchyma at 48hrs postmortem, it is ... -
Exploring the Vulnerabilities of Traffic Collision Avoidance Systems (TCAS) Through Software Defined Radio (SDR) Exploitation
(Virginia Tech, 2019-06-13)Traffic Collision Avoidance Systems (TCAS) are safety-critical systems that are deployed on most commercial aircraft in service today. However, TCAS transactions were not designed to account for malicious actors. While ... -
Mount Interference and Flow Angle Impacts on Unshielded Total Temperature Probes
(Virginia Tech, 2019-06-12)Accurately measuring the total temperature of a high-speed fluid flow is a challenging task that is required in many research areas and industry applications. The difficulty in total temperature measurement generally stems ... -
Ionospheric Sounding During a Total Solar Eclipse
(Virginia Tech, 2019-06-12)The ionosphere is a constantly changing medium. From the sun to cosmic rays, the ionosphere proves to be a continually interesting area of study. The most notable change that occurs in the ionosphere is the day and night ... -
Enhancing Trust in Autonomous Systems without Verifying Software
(Virginia Tech, 2019-06-12)The complexity of the software behind autonomous systems is rapidly growing, as are the applications of what they can do. It is not unusual for the lines of code to reach the millions, which adds to the verification ... -
Creation of a Cognitive Radar with Machine Learning: Simulation and Implementation
(Virginia Tech, 2019-06-12)In this paper we address radar-communication coexistence by modelling the radar environment as a Markov Decision Process (MDP), and then apply Deep-Q Learning to optimize radar performance. The radar environment includes ... -
