Trusted Software Updates for Secure Enclaves in Industrial Control Systems
(Virginia Tech, 2017-09-18)Industrial Control Systems (ICSs) manage critical infrastructures such as water treatment facilities, petroleum refineries, and power plants. ICSs are networked through Information Technology (IT) infrastructure for remote ... -
Condensation Frosting: From Ice Bridges to Dry Zones
(Virginia Tech, 2017-09-18)The most ubiquitous mode of frost formation on substrates is condensation frosting, where dew drops condense on a supercooled surface and subsequently freeze, and has been known since the time of Aristotle. The physics of ... -
Development of CAD Platform Independent Software for Automatic Grading of Technical Drawings
(Virginia Tech, 2017-09-15)Spatial visualization is the ability of an individual to visualize an object mentally and understand its spatial orientation. It plays an important role in engineering. There have been multiple works that show that spatial ... -
Biophilic Design: Transitional Housing for Homeless Veterans
(Virginia Tech, 2017-09-14)How can Architecture and Nature work together to create healing spaces? The purpose of this thesis was to study the relationship between nature and architecture. Today, rapid growth in cities and urbanization has cause ... -
The Impact of Working with Human Sex Trafficking Survivors on Clinicians' Personal and Professional Lives
(Virginia Tech, 2017-09-14)This qualitative phenomenological study considered the experience of a clinician working with victims and survivors of human sex trafficking and their families. In the overwhelming majority of cases, family members were ... -
The Isolation of Cellulose Nanocrystals from Pistachio Shells and Their Use in Water Actuating Smart Composites
(Virginia Tech, 2017-09-14)Composites are a category of materials where two or more materials are used together to enhance each of their strengths. Such materials are often used in airplanes, spacecraft, sporting equipment, and many high-end products. ... -
A Pilot Study for Identifying Tasks and Degrees of Visual Fidelity for Applications of Head Mounted Display Systems for Construction
(Virginia Tech, 2017-09-14)The rise in technology and reduced costs has led to more research on the use of Augmented Reality (AR). However, applications for AR Head Mounted Display (HMD) systems are still being defined. AR HMD systems have potential ... -
Rest Area Wilderness Experience: Reimagining the Design of Rest Areas on Interstate 64
(Virginia Tech, 2017-09-14)Wilderness has inspired the imagination and passion of Americans for the past two centuries. However, the places that are most often designated as wilderness are frequently far away and difficult for most people to access. ... -
Development and Exploratory Findings of a Smartwatch Interface to Facilitate Group Cohesion in a Statewide Health Promotion Program
(Virginia Tech, 2017-05-25)Background: Physical inactivity of the general population is a major public health concern in the US and around the world. Community-based interventions that include evidence-based principles of group dynamics are effective ... -
Utilizing High Resolution Data to Identify Minimum Vehicle Emissions Cases Considering Platoons and EVP
(Virginia Tech, 2016-03-22)This paper describes efforts to optimize the parameters for a platoon identification and accommodation algorithm that minimizes vehicle emissions. The algorithm was developed and implemented in the AnyLogic framework, and ... -
Eco-Cooperative Adaptive Cruise Control at Signalized Intersections Considering Vehicle Queues
(Virginia Tech, 2016-03-22)Traffic signals typically produce vehicle stops and thus increase vehicle fuel consumption levels. Vehicle stops produced by traffic signals, decrease vehicle fuel economy on arterial roads making it significantly lower ... -
Active Flight Path Control for an Induced Spin Flight Termination System
(Virginia Tech, 2017-09-12)In this thesis, we describe a method for controlling the cycle-averaged velocity direction of a fixed-wing aircraft in an unpowered, helical descent. While the aircraft propulsion system is disabled, either intentionally ... -
A Hyperspectral Imager for a Cubesat to Identify Ocean Ship Parameters
(Virginia Tech, 2017-09-12)A Hyperspectral imager aboard a cubesat would be able to provide images which could be used to identify ships and determine the ship's length and breadth and heading. Depending on the size of the ship, the speed the ship ... -
