California Printing History And The Shakespeare Press Museum, Laura Sorvetti

Master's Theses

The Shakespeare Press Museum, a working letterpress museum at Cal Poly, San Luis Obispo, houses letterpress printing presses and equipment dating from the 1850s to the 1970s. Although the museum has been at Cal Poly since the 1960s, little work was completed on the historical context of the collections or to address the archival and educational frameworks of the museum’s collection. This thesis has three purposes: to place the museum’s collections in their nineteenth-century California historical context; to provide the first in-depth examination of the museum’s original founder, Charles “Shakespeare” Palmer; and to create an archival reference and program for …

Assessment Of Morphology And Hemodynamics In Normal And Remodeled Microvasculature With Parameter Sensitivity Analysis, Shilpi Ghosh

Master's Theses

The goal of this study was to compare the morphological and hemodynamic characteristics of normal and remodeled vascular networks in the mouse gracilis muscle. To this end, previously developed models to assess flows and vascular branching were used to assess the normal and remodeled microcirculatory networks. The analysis revealed that the average individual vessel flow rates for vessels of similar caliber and total volumetric flow rates in the networks do not change for vessels of the same caliber after remodeling. Connectivity changes and average diameters primarily change in the larger arterioles after remodeling. A few correlations could be made between …

"For Such Is A Friend Now": Reflection And Revision In Shakespeare's Comic Friendships, Leah Rainell Boudreaux

Master's Theses

In early modem England, "friendship" was a term both flexible and deeply fraught. It could apply to a wide range of relationships, including, for example, those between family members, lords and tenants, or male members of the aristocracy. The ideals associated with friendship at that time had a profound impact on the way that the relationship was represented both in a historical and literary sense. During that time, William Shakespeare crafted remarkable and resonating depictions of friendship which have endured the through the ages. The distinction between Shakespeare's work and the work of other early modem writers lies in the …

Design And Implementation Of User Level Socket Application Programming Interface With Socket Splitting And Mediation, Scott Walter Holzer

Master's Theses

Over the past few decades, the size and scope of the Internet has grown exponentially. In order to maintain support for legacy clients, new applications and services have been limited by dependence on traditional sockets and TCP, which provide no support for modifying endpoints after connection setup. This forces applications to implement their own logic to reroute communications to take advantage of composable services or handle failover. Some solutions have added socket operations that allow for endpoints to be redirected on the fly, but these have been limited in scope to handling failover and load balancing.

The "F" Word: An Exploration Of Feminist Identity In Undergraduate Students, Emily Michelle Hedstrom-Lieser

Master's Theses

While the majority of women living in the U.S. agree with feminist inspired goals, few claim a feminist identity. This study explored predictors of feminist identification in a sample of 233 undergraduate women at a mid-western university in the Rocky Mountain region. Exploratory factor analysis was used to identify themes, and scales were assembled for use in OLS regression. Significant predictors of feminist identification included believing in the relevance of feminism in contemporary social issues, current exposure to feminism, support for feminist goals and ideals and recognition of women's differential access to resources. Research findings suggest that current exposure to …

Asynchronous Mips Processors: Educational Simulations, Robert L. Webb

Master's Theses

The system clock has been omnipresent in most mainstream chip designs. While simplifying many design problems the clock has caused the problems of clock skew, high power consumption, electromagnetic interference, and worst-case performance. In recent years, as the timing constraints of synchronous designs have been squeezed ever tighter, the efficiencies of asynchronous designs have become more attractive. By removing the clock, these issues can be mitigated. How- ever, asynchronous designs are generally more complex and difficult to debug. In this paper I discuss the advantages of asynchronous processors and the specifics of some asynchronous designs, outline the roadblocks to asynchronous …

Master's Theses

This study is a comprehensive look into the response and recovery of an anthropogenic induced sediment infill of a bottom land hardwood wetland at Camp Shelby Training Site (CSTS) in Perry and Forrest Counties, Mississippi. Lack of sediment control structures (sediment fences and matting), combined with high rainfall, led to erosion within and around the Multi Purpose Range Complex-Heavy (MPRC-H) during its construction. Deposition of sediment effected approximately 20.2 hectares of wetlands that have been monitored since the event occurred in 2005. To better understand the recovery process, the study area was compared to the Cypress Creek Mitigation Area (CCMA) …

"Civilized My Syphilized Yarbles": Culture, Economy, And Deviant Youth Subcultures In Anthony Burgess' A Clockwork Orange, Emily Joy Carpenter

Master's Theses

This thesis utilizes Anthony Burgess' A Clockwork Orange to develop a new discussion concerning the impact of the emergence of youth subculture on society in England in the 1950s. Youth subcultures like the Nadsats and the Teddy Boys developed a new style that undermined the social taboos, and in doing so, attempted to create a sense of identity that was separated from their parents and existing forms of both high and low cultures. However, instead of transcending these sources of authority and identity, the language and style of these new subcultures actually only provided the illusion of difference from society. …
