Bulk Glass As Compressive Reinforcement In Structural Elements, John Cotter
Bulk Glass As Compressive Reinforcement In Structural Elements, John Cotter
USF Tampa Graduate Theses and Dissertations
All composites are formulations of materials that allow for the improvement of material properties by compositing materials with differing properties. For example, straw, which has a low compression strength and stiffness but relatively high tensile stiffness, composites well with clay, which has a high compression stiffness and low tensile strength, to create a material that utilizes a clay base with straw to greatly improve the strength of clay. In general, the most economical composites are those that combine a low-cost binder, or matrix, with higher strength reinforcing materials.
Contrary to popular knowledge, bulk glass is an exceedingly strong material when …
Fluorochlorozirconate Glass Ceramics For Photovoltaic And Computed Radiography Applications, Russell Lee Leonard
Fluorochlorozirconate Glass Ceramics For Photovoltaic And Computed Radiography Applications, Russell Lee Leonard
Doctoral Dissertations
Fluorochlorozirconate (FCZ) glass ceramics are versatile materials whose optical properties may be tuned through compositional or processing changes. For this work, FCZ glasses were synthesized, and then subsequently heat treated to create optically-active glass ceramics. The glasses and glass ceramics were characterized using a number of methods including differential scanning calorimetry, phosphorimetry, x-ray diffraction, and spectrophotometry. Samples were evaluated for applications in photovoltaics and computed radiography–especially those pertaining to intraoral dental radiography and portal imaging.
The ability of FCZ glass ceramics containing hexagonal barium chloride nanocrystals doped with the rare earth elements, holmium and europium, to downshift ultraviolet light to …
The Visual Representation Of Sound For The Hearing Impaired, Jonathan Brophy
The Visual Representation Of Sound For The Hearing Impaired, Jonathan Brophy
Electrical Engineering
There are many difficulties that arise when one is faced with a hearing disability. New applications of advancing technology have the potential to enable designs capable of assisting the hearing impaired with the ability to see sound. This project seeks to provide a user with a visual representation of loud noises detected using small directional microphones. The microphones determine the location of the sound above a set decibel level and a microprocessor determines the approximate location of the sound source and displays a vertical colored bar on a video image in the direction of the noise using virtual reality glasses. …
