Hybrid Active Power Filter with Output Impedance Control
(Virginia Tech, 2006-05-24)
In an ideal world, unwanted or undesirable effects in a system could and would be completely ignored. In fact, this was the case in mid-80s' PC design when an 80286 microprocessor running at a "blazing" 12 MHz was considered ...
Test of Light Speed Constancy With Light Age Using an Active Fiber-Based Mach-Zehnder Interferometer
(Virginia Tech, 2006-05-10)
This thesis investigates the constancy of light speed with respect to the light age using an active fiber-based Mach-Zehnder interferometer (MZI) illuminated by sunlight. The original sunlight in one arm, which has the age ...
Implementation of Third Order Plate Theory for use in Existing Finite Element Software
(Virginia Tech, 2006-05-12)
Sandwich plates and layered composites are common in many structural applications because of their combination of high stiffness and low weight. These plates combine top and bottom layers of high Young's modulus with ...
Magnetic Induction for In-situ Healing of Polymeric Material
(Virginia Tech, 2006-05-19)
The field of self-healing materials is growing dramatically due to the obvious in- centive of having structural materials with the ability to repair damage. Some polymers have demonstrated the ability to heal from damage ...
Durable Sandwich Structure Joining Technology for NASA's Ares V Launch Vehicle
(Virginia Tech, 2010-02-05)
Joining of uniformly-curved composite sandwich panel segments, typical in state of the art aerospace launch vehicles, should be mass-efficient. Adhesively bonded joints can provide increased mass-efficiency over ...
The influence of land use on the quality of seston in southern Appalachian stream ecosystems
(Virginia Tech, 2006-05-12)
Seston is the complex of organic and inorganic particles suspended in the water column in stream ecosystems. This detrital pool is a significant vector of energy and nutrients from headwaters to the ocean. Many of the ...
Let's All Go to the Movies
(Virginia Tech, 2006-05-10)
Welcome to the movies! Welcome to the stars! Welcome to this grand illusion! All of it's yours.
New Urbanism. Hollywood thinks you're stupid. Scientology. Retro-futurism. Taking back color from toiletries. Personal politics. ...
Characteristics of muscle co-contraction during isometric tracking
(Virginia Tech, 1992)
The purpose of this research was to study the relationship between muscle coordination and the performance of a simple manual tracking task. The study employed an isometric, zero order, pursuit tracking task with a laterally ...
The evaluation of corrosion inhibitors for the repair and rehabilitation of reinforced concrete bridge components
(Virginia Tech, 1992)
In 1991, seven corrosion inhibitors, surface applied liquids and concrete admixtures, were identified as promising for the repair of reinforced concrete structures subject to chloride induced corrosion.
Small scale (1 ...
