Open Space Planning; Utilizing Green Infrastructure To Preserve Community, Cynthia V. Reynolds

Master's Theses

Current sprawl development patterns typical of contemporary development in the United States are unsustainable. The uniform development guidelines prevent context sensitive community design, degrading our communities and consuming large amounts of natural and cultural resources. Significant progress has been made in reorganizing community planning towards sustainable development practices. However, these alternatives still work under the misconception that there is a disconnect between planning open space networks and planning development. Through a comprehensive land use planning approach, this project explores combining concepts of landscape ecology, green infrastructure planning and conservation subdivision patterns to design an integrative open space/community network.

The Power Of Networks: Social Capital And Its Influence In College Student Perceptions Of Sexual Harassment Of Female Sports Reporters, Brittany M. Perotti

Master's Theses

For decades, women have sought legal remedy as they tried to break through the metaphorical glass ceiling in a male-dominated workforce. In their efforts to make it to higher positions of power, many endured the subtle taunts and comments, while others struggled with blatant discrimination and environments that clearly did not welcome women (Hardin & Shain, 2005a; 2005b), including their own place of work (Hardin & Whiteside, 2009). In multiple studies, female sports journalists admitted to sexual harassment, but dismissed it as part of the job (Hardin & Shain, 2006; 2005a; 2005b). Public outcry over this phenomenon is minimal, and …

A Neural Network Receiver For Em-Mwd Communication, Timothy P. Whitacre

Master's Theses

Baseband digital communication in electro-magnetic measurement while drilling (EM-MWD) systems is often corrupted by non-white surface noise. The inability to reliably decode the transmitted signals in a noisy environment limits the depth at which EM-MWD systems can operate. Correlation receivers, which are optimal in the presence of additive white Gaussian noise, can be sub-optimal in the presence of various types of field noise at different drilling sites.

This thesis investigates the application of artificial neural networks (ANN) as communication receivers in EM-MWD baseband digital communication systems. The performances of various ANN architectures and training algorithms are studied and compared with …

Rfid Classroom Management System, Andrew W. Wright

Master's Theses

Professors who manage large classes are unrealistically expected to grade each student fairly and accurately.  Even with all of the technological advancements that have occurred in the past thirty years, very little progress has been made in classroom management, and as a result, professors are not equipped with enough tools to successfully manage large class sizes.  Because radio frequency identification (RFID) technology is making its way into student issued identification cards, there is an opportunity to use it as a tool to aid professors in the classroom.  The focus of this paper is to discover the most effective system that …

Expanding Planning Public Participation Outreach Through Social Networking, Wesley Brian David Harris

Master's Theses

Public participation is not a form of civic responsibility that it once was. With not only fewer people taking part in the public participation process, there is a trend towards an older (45 years and older) group of residents that come to such meetings or workshops. Plans, such as Specific Plans or General Plans often take years to implement and require all generations to give feedback on what is needed for the future. Additionally, within the last decade, there has been a rise in social media websites such as Facebook and Twitter. These websites emerged as informal virtual places for …

Learning To Fly: The Untold Story Of How The Wright Brothers Learned To Be The World's First Aeronautical Engineers, Daniel Lawrence Slusser

Master's Theses

This paper examines the education, events, and experiences of the Wright brothers in order to determine how they developed the necessary skills to engineer the first viable aircraft. Without high school diplomas, and with no advanced formal education, the Wright brothers were able to develop aircraft that far exceeded the capabilities of aircraft designed and built by professional engineers that had worked on the problem of flight for much longer and with substantially larger research budgets. I argue that the Wright brothers’ success resulted from their experiences in the printing and bicycle industries as well as their formal and informal …

Development Of A Cubesat Instrument For Microgravity Particle Damper Performance Analysis, John Trevor Abel

Master's Theses

Spacecraft pointing accuracy and structural longevity requirements often necessitate auxiliary vibration dissipation mechanisms.  However, temperature sensitivity and material degradation limit the effectiveness of traditional damping techniques in space.  Robust particle damping technology offers a potential solution, driving the need for microgravity characterization.   A 1U cubesat satellite presents a low cost, low risk platform for the acquisition of data needed for this evaluation, but severely restricts available mass, volume, power and bandwidth resources.  This paper details the development of an instrument subject to these constraints that is capable of capturing high resolution frequency response measurements of highly nonlinear particle damper dynamics.

Food & Shelter: Low-Income Housing Tax Credit Developments In California And Access To Grocery Stores, Darci Coleen Palmer

Master's Theses

Since the mid-century proliferation of public housing, policy makers and environmental justice advocates have exposed the fact that geographically and economically isolated public housing sites are ultimately detrimental to residents and communities. In recent years, more progressive housing policies have emphasized the importance of site location in the success of housing programs. This study explores the intersection of affordable housing policy and “food desert” research, by assessing the Low-Income Housing Tax Credit (LIHTC) program in California, with specific attention to the grocery store category within the Site Amenities section. Since the inception of the LIHTC program in 1986, the California …

In the case of buffers, academic literature is examined to determine how effective buffers are at various tasks (filtering runoff, mitigating dust and wind, providing habitat, etc.) and how to construct buffers to maximize their effectiveness. Land use plans and codes from several California jurisdictions are studied to see how buffers are put to use. Academic literature …

Automated Sg-Dbr Tunable Laser Calibration Optimized For Optical Coherence Tomography Applications, Christopher Louis Chiccone

Master's Theses

SG-DBR lasers look to solve many problems associated with present OCT sources by being cost effective, smaller in size, more robust, and by operating at faster repetition rates.  Swept Source Optical Coherence Tomography (SS-OCT) requires a tunable laser source that exhibits linear frequency sweeps, large frequency spans, and high repetition rates.  This work accomplishes this by using four synchronized waveforms sent to the input of a Sampled Grating-Distributed Bragg Reflector (SG-DBR) laser.  Three mirrors control the wavelength, while an internal semiconductor optical amplifier controls the laser output power.  In dealing with this complicated tuning mechanism, a manual sweep calibration is …
