Solitude is a National Register historic property that is today a central part of the Virginia Polytechnic Institute and State University campus. The property was purchased in 1872 to create the site of the land-grant college that later became VPI. The focus of this study is a log dependency associated with the extant nineteenth century mansion on the property. Both buildings have suffered extensively from deterioration in recent years, but are now receiving some attention. By substantially augmenting a historic structure report on the outbuilding filed in 1989, this thesis contributes to the building's documentation and accurate interpretation. As one of two early structures on the site that still retains a large percentage of its original fabric, it is an important artifact that should be preserved for posterity. Documentation through meticulous research is an important part of preservation. When the building is physically gone, knowledge of it will survive. Little was known about the dependency prior to the completion of this research. The best guess on its age appears to have erred by thirty years. The building's original function has long been the subject of debate. If it was a dwelling, there are no historic documents by which to identify the occupants. This study examines various aspects of the building, including its present condition, construction practices and materials, dimensions, form and function, location, age, historical context, and buried cultural deposits around the building. The biological agents that have attacked and caused severe deterioration of the building are identified, as well as the conditions that precipitated the attacks. The methods employed or explored in this research include archaeological excavations, artifact analysis, relative dating methods, wood identification and pathology, dendrochronology, basic chemistry, database generated spatial imaging, library searches, measured drawing, and photography. Use of these methods has provided insightful information regarding construction materials and their properties, construction practices, date of construction, and the history of the building's use and maintenance. Information about the building's occupants has also come to light, such as their socio-economic status, their standard of living, i.e. the goods they consumed and the comfort of their quarters, and their refuse disposal practices. Considering all the information revealed, a strong case is made that the building was originally a domestic slave's dwelling, constructed in the early 1840s. / Master of Science

The focus of this thesis is the imposition of order onto a non-ordered space through the design of boundaries. The designed elements are derived from both the existing site conditions and the desire to improve the space, a threshold to the stadium. A building that acts as a boundary becomes a type of wall, having two very pragmatic sides. Therefore, in this case, these elements must also function as a filter. The challenge is to design a boundary or an edge condition which defines the site, in addition to framing the views and allowing people to pass through these thresholds. Likewise, circulation also helps to structure the site. The designed buildings allow for persons to pass along as well as to pass through. The elements placed onto the site allow for both formal and direct paths through the site, as well as more general and autonomous approaches to the stadium, located on the edge of the site. / Master of Architecture

The study has two objectives: to develop a methodology to identify success criteria for the VT CRC and to communicate outputs (success criteria) to selected members of the VT CRC’s stakeholders. A methodology is developed to identify success criteria based on the VT CRC's primary objectives. These primary objectives are: technology transfer and economic development. The purposes of a methodology are to place the VT CRC within the framework of Virginia Tech's larger missions and then to identify success criteria. A methodology consists of seven steps. There are thirteen success criteria which have been identified by a methodology. A methodology is based on management systems engineering theories, concepts, and tools/techniques. The study communicates outputs from a methodology by a questionnaire. Questionnaires will be sent to twelve selected members who are from the VT CRC, the university, tenants, and Town of Blacksburg. Their responses will be analyzed to decide whether these outputs are success criteria for the VT CRC and whether a methodology accomplishes its purposes. Furthermore, a background of Virginia Tech and a concept of university-related research parks will be discussed. Included in a discussion of Virginia Tech are missions, a modern view of a land-grant university, and roles of the Virginia Tech Foundation. Included in a discussion of research parks are purposes, benefits, and drawbacks. / Master of Science

Following the mass shooting at Virginia Tech on April 16, 2007, institutions of higher education appeared to restructure themselves and change the way that they worked with students who may pose a risk to self or others. They formed committees, sometimes known as Communities of Concern, to help review these concerns and respond appropriately. The purpose of this study was to examine how the Community of Concern Committee at the University of Kentucky was developed following the incident at Virginia Tech. Particular attention was focused on the change and learning that took place. Using the frames of single-loop and double-loop learning, this study examined six oral history accounts of the development of the Community of Concern Committee at the University of Kentucky. The oral histories coupled with historical documents provided a timeline of events related to the development of the committee. In addition, the oral histories revealed a complex learning process which blended single and double-loop learning to guide this institutional change. The comparison between this incident and other legal issues within higher education was explored as well as the opportunity to expand this exploration outside of the current case study.

On-blade hot wire anemometry measurements as well as far field sound measurements at several receiving angles have been previously made for a rotor partially embedded in a boundary layer. The inflow distortion effect on the rotor angle of attack distribution was determined directly from the on-blade measurements, and was found to minimally affect the angle of attack at the blade tips and lower the angle attack in the rotor disk plane as the radial location moves towards the hub. A narrow, sharp increase in angle of attack as the rotor blades approached the wall was also observed, indicating blade interaction with flow reversal. The haystacking pattern, or spectral humps that appear at multiples of the blade passage frequency, was studied for a wide range of advance ratios. At high advance ratios, evidence of vortex shedding from the blade trailing edges was observed. For low advance ratios, the haystacks narrowed, became more symmetric and increased in number. A method of determining the average acoustic signature of an eddy passage through a rotor was developed from time delay aligning multiple microphone signals and eddy passages detected using the continuous wavelet transform. It was found that the eddy passage signatures were similar to a cosine wave with a Gaussian window. It was also found that normalized timescales obtained directly from the eddy passage signatures remained somewhat constant with advance ratio, but increases slightly for fixed free stream velocities with increasing rotor RPM. For advance ratios less than 0.6, the eddy passage signatures were dominated by a tonal component due to rotor ingestion of misaligned flow caused by a boundary layer separation at the wall. This indicates that flow reversal known as the Pirouette Effect is interacting with the rotor blades. / Master of Science

Allochthonous nutrients were monitored during three storm events on one of the major tributaries entering the shallow VPI&SU Duck Ponds. Autochthonous nutrients were monitored for a period of ten months. During these storms, the stormwater runoff contributed large amounts of organic matter and fertilizer nutrients that settled in the ponds and during anoxic conditions, recycled to stimulate algal blooms. Alum was applied to one pond to reduce internal cycling of nutrients. A 25 mg/L dose of alum produced an aluminum hydroxide floc that settled to the bottom and afterwards, lowered othophosphate-phosphorus concentrations below 10 µg/L in the water column. The longevity of the one-time treatment in reducing the sediment-phosphate release rate is unknown because the monitoring program was not continued beyond July of 1988. A pond-treatment program involving copper sulfate was initiated to control algal blooms consisting mainly of the green alga, Chlamydomonas. Based on the complexing properties of the water, such as alkalinity and humics, a copper sulfate dose of 13.6 kg was determined to be a safe and effective dose that reduced algal densities but did not result in any visible adverse effects upon other aquatic life. Both of the pond management schemes were designed to aid managers of small urban ponds who have low operating budgets and a lack of technical equipment. / Master of Science

The objective of this study was to develop a voice interface for the on-line catalog of VTLS. Three major components of the system, namely, voice recognition system, text-to-speech synthesizer, and screen review program, were identified. These components were selected after a comparative study of several commercially available systems. Once the components were selected they were integrated to form a complete voice recognition and synthesis system. Using this system, a voice interface was realized to suit the operations of VTLS. A telephone interface for the system was investigated and recommendations were made for future research. / Master of Science
