To Protect The Sky From Falling, Charles Lambert
To Protect The Sky From Falling, Charles Lambert
Theses and Dissertations
Using ceramic, found objects, metal and wood, my practice is a meditation and questioning of care, efficiency, repair, structure and place. Architectural elements of support rendered in clay are the initial point of entry to give a soft, lived-in quality to a built environment that is often devoid of the mark of the hand and body. Imprints of the hand are left, and the objects are often deformed in ways to subvert the perceived functionality. The focus on ceramics centers around a play with the binary of soft and hard and the external changes that create its transformation. The work …

An Application Of The Sleuth Model: Future Urbanization Of Davidson County, Tennessee, Caitlyn J. Linehan
Theses and Dissertations
As the urban population is expected to grow in the coming decades, there is pressure on urban areas to expand to accommodate this growth. Often times, these expansions are not sustainable, they consume valuable lands and cause significant environmental, social, and economic burdens, a theory which is known as urban sprawl. Therefore it is often imperative to model areas more likely to urbanize in order for cities to plan for their expansion in the most sustainable way possible. Nashville, Tennessee located within Davidson County is an area that has been experiencing a significant period of urban growth. The objective of …
Hopeless Heartland: Space And Labor In Virginia, Katrina Hamilton
Hopeless Heartland: Space And Labor In Virginia, Katrina Hamilton
Theses and Dissertations
In the US, labor market conditions vary by demographics and space. Though space has been shown to be highly related to labor force outcomes, lower-level analyses are under-utilized as statistical workforce analyses tend to rely on national or state-level data. This study addresses variability in labor markets by taking a spatial approach, using cluster analysis and logistic regression to explore variations in labor market variables across census tracts in Virginia. Cluster analysis reveals several hot and cold spots of key labor market indicators: rates of marriage, poverty, educational attainment, and income. In many cases, poor social conditions, such as low …
The Catalyst Effect Of Historic Preservation: A Spatial Analysis Of The Impact Of Historic District Designation On Housing Renovations In New York City, Ali R. Mostafa
Theses and Dissertations
The constraints on property use along with the economic merits of historic districts are critical points in the debate over preservation policies. Improving the existing housing stock is a substantial economic activity and a significant part of the nation’s overall construction industry. The purpose of this study is to present an empirical analysis of the relationship between historic district designation and renovation decisions. The results of the analysis found that historic preservation does not inhibit the renovation activity of single-family homeowners. However, contrary to the claims made by proponents, it does not give a powerful incentive for owners in undesignated …

Experimental trials that would have taken over 100 years on a desktop computer were completed in weeks using a high-performance computer containing over 125,000 cores. The results of the optimizer clearly …
Open / Close: Assimilating Immersive Spaces In Visual Communication, Anika Sarin
Open / Close: Assimilating Immersive Spaces In Visual Communication, Anika Sarin
Theses and Dissertations
I am interested in two spaces obverse to each other: open and closed. An open space develops organically based on how people inhabit it. Interacting with an open space is a dynamic, sporadic, multisensory, immersive, and subjective experience. In such spaces, we are confronted with an alternative aesthetic, one that is in conflict with the seamlessness of a closed space. A closed space is anchored on definite variables like structure, use and boundaries. While interaction between people and space is important, the space is tightly controlled and interaction is designed. Through this thesis project, I present a method that metaphorically …

Vision-Aided Cooperative Navigation For Multiple Unmanned Vehicles, Jason K. Bingham
Vision-Aided Cooperative Navigation For Multiple Unmanned Vehicles, Jason K. Bingham
Theses and Dissertations
In the recent past, a shift has taken place from manned to unmanned Intelligence, Surveillance, and Reconnaissance (ISR) missions. This shift has lead to an increase in the number of unmanned vehicles (UV) operating in a theater. Additionally, removal of the crew allows for a reduction in vehicle scale, which leads to an increased ability to operate in GPS degraded environments. With the loss of GPS signals the vehicles must rely on Inertial Navigation Systems (INS) which when reduced to an appropriate size are inherently inaccurate. This research endeavors to exploit three attributes of increased UV use for ISR missions. …
