Information Security: A Study On Biometric Security Solutions For Telecare Medical Information Systems, Ramon Andrew Whitman
Information Security: A Study On Biometric Security Solutions For Telecare Medical Information Systems, Ramon Andrew Whitman
Master's Theses and Capstones
This exploratory study provides a means for evaluating and rating Telecare medical information systems in order to provide a more effective security solution. This analysis of existing solutions was conducted via an in-depth study of Telecare security. This is a proposition for current biometric technologies as a new means for secure communication of private information over public channels. Specifically, this research was done in order to provide a means for businesses to evaluate prospective technologies from a 3 dimensional view in order to make am accurate decision on any given biometric security technology. Through identifying key aspects of what makes …
Molecular Dynamics Simulations Of A Pentacene Derivative On Gold Surfaces In The Quantum Mechanical And Classical Mechanics Frameworks, Ryan Allen Miller
Molecular Dynamics Simulations Of A Pentacene Derivative On Gold Surfaces In The Quantum Mechanical And Classical Mechanics Frameworks, Ryan Allen Miller
Master's Theses and Capstones
With increasing potential to serve as a basis for constructing organic photovoltaic de- vices, the directed self-assembly of small organic molecules on metal substrates provides an interesting new method of bottom-up device building. By utilizing the qualities inherent in the substrate and molecules, one can manipulate surface topology to create functional layers of molecules in a desired configuration. However, tailoring these organic layers in a useful way requires detailed analysis of the substructure characteristics. With top-down visualization approaches like Scanning Tunneling Microscopy (STM) pro- viding a limited view of assembled layer structural characteristics, molecular dynamics sim- ulations must be employed …
An Objective Protocol For Movable Bridge Operation In High-Wind Events Based On Hybrid Analyses By European And American Design Code, Timothy Prescott Nash
An Objective Protocol For Movable Bridge Operation In High-Wind Events Based On Hybrid Analyses By European And American Design Code, Timothy Prescott Nash
Master's Theses and Capstones
Movable bridges play an integral role in modern transportation infrastructure. As means of passage for both vehicular and naval traffic at a single location, their reliable performance is a necessity. However, with the thousands of movable bridges in the US – which are typically located in coastal environments that are typically highly susceptible to extreme weather events – there are few objective protocols defining the environmental conditions in which they can be safely operated. In order to define such conditions, wind speed and temperature variable wind loads were developed using multiple, structural load development codes for a case study site: …
Ductility Of 304 Stainless Steel Under Pulsed Uniaxial Loading, Graham Webb Cullen
Ductility Of 304 Stainless Steel Under Pulsed Uniaxial Loading, Graham Webb Cullen
Master's Theses and Capstones
The enhanced ductility that 304 stainless steel is exhibited under pulsed loading (Zhang, 2009) is investigated here using a combination of experiments and analysis. The simplest loading case, i.e., uniaxial tension, was selected to avoid the complicating effects of multiaxial stress states and/or contact and friction with a rigid die. Three types of tensile tests were performed: monotonic, pulsed and hold. For a range of strain rates, the pulsed and the hold tests exhibited different elongation-to-fracture from the monotonic tests. Digital image correlation and infrared thermography were employed to further probe this behavior. It was discovered that since the pulsed …
Impact Of Silo Storage Time And Specimen Fabrication Methods On Hot Mix Asphalt Mixtures, Christopher Daniel Jacques
Impact Of Silo Storage Time And Specimen Fabrication Methods On Hot Mix Asphalt Mixtures, Christopher Daniel Jacques
Master's Theses and Capstones
Performance of asphalt as a pavement material depends on a variety of factors such as mixture properties, the mix design process, and the way in which the materials are produced and placed. There are also different methods and practices in hot mix asphalt construction, such as the way in which specimens are fabricated for laboratory testing and the time that hot mix asphalt is stored at plants following production. There is currently a lack of understanding within the asphalt industry on the potential performance impacts of these variations. This thesis involves two projects that explored variations in the production and …
