Analysis Of Mammoth Cave Pre-Park Communities, Matthew Brunt

Masters Theses & Specialist Projects

Before the creation of Mammoth Cave National Park, this area was home to numerous communities, each with a sense of identity. To prepare for the creation of the National Park, all residents living within these communities were relocated, and many of these communities were lost to the passage of time. Today, public memory of these lost communities is being fostered by the descendents of the pre-park area.

Through the use of a Historical Geographic Information System, 1920 Edmonson County manuscript census data, and statistical analysis, the demographic composition of these lost communities was explored. This project not only brought to …

Heirloom And Hybrid Tomato Yield And Quality In Organic And Conventional Production Systems, Diana J. Edlin

Masters Theses & Specialist Projects

Due to the recent changes in the economy of Kentucky tobacco production, some producers are seeking an alternative crop that will provide similar economic gains to tobacco without needing more acreage. Tomatoes are an existing crop in Kentucky that have been declining in acreage over the last five years. There is evidence to suggest that, through niche and local marketing, tomatoes may be able to fill the void left by tobacco. However, there is concern among producers that they will lose yield and/or quality if they switch to one of these niche production systems or cultivars.

"All The Crises Reached A Concerted Crescendo" - The Arab Oil Embargo And Why The United States Was Unprepared For It, Jonathan D. Chilcote

Masters Theses & Specialist Projects

During the 2008 spike in oil prices, oil companies and government officials were brought under close scrutiny as many Americans began to question why prices were able to rise so quickly. Americans had become accustomed to living in an economy where cheap oil was the norm, and demanded answers when that situation changed. What most of them did not know is that they were repeating history and mimicking the response to the 1973 oil embargo. Just as in 2008, the United States faced a crisis in 1973 with which it was unprepared to effectively cope. This thesis analyzes the reasons …

Detection And Measurement Of Water Stress In Vegetation Using Visible Spectrum Reflectance, Arthur Zygielbaum

Department of Geography: Dissertations, Theses, and Student Research

At any scale, from a single microbe to the planet that nurtures us, water defines our place in the universe. It provides the hydraulic forces needed to give plants structure, and the medium enabling photosynthesis, the basis for most life on Earth, to occur. Knowledge of plant water status is vital to understanding the state or condition of vegetation, information which is essential to disciplines as diverse as agriculture, geography, and climatology. Non-destructive and remote sensing of plant water status allows the gathering of such information across wide geographic extents and over long periods of time. Monitoring vegetation remotely requires …

Overall, there is a lack of academic and professional literature about ISM and more specifically IS culture in Saudi Arabia. Therefore, the overall aim of this paper is to identify issues and factors that assist the implementation and the adoption of IS culture and practices within the Saudi environment. The goal of this paper is to identify the important conditions for creating an information …

Review Of The Evidence Used In The Description Of Currently Recognized Cetacean Subspecies, William F. Perrin, James G. Mead, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

We reviewed the subspecies listed by Rice (1998) and those described since (a total of 49, in 19 species), assessing them against the criteria recommended by the recent Workshop on Shortcomings of Cetacean Taxonomy in Relation to Needs of Conservation and Management (Reeves et al., 2004). The workshop suggested that the subspecies concept can be construed to cover two types of entities: a) lineages diverging but not quite far along the continuum of divergence (still having significant gene flow with another lineage or lineages) to be judged as species, and b) lineages that may well be species but for which …

Decision Making In Entrepreneurial Finance: A Behavioral Perspective, Rassoul Yazdipour

The Journal of Entrepreneurial Finance

Central questions in entrepreneurship and entrepreneurial finance are briefly discussed and case is made for the need for applying the behavioral finance theories and models to better understand the decision making dynamics that is involved at each stage of the entrepreneurial process. By dissecting a venture's total risk into a "Resident Risk" component and a "Behavioral Risk" component, attempt is made in this writing to introduce a preliminary risk model for evaluating key retrepreneurial decisions like the decision to launch and fund a new venture. Although the focus here is on individual decision making under highly uncertain entrepreneurial environments, but …

Thermodynamically Consistent Large Deformation Constitutive Model For Glassy Polymers, Ashwani Kumar Goel

Department of Engineering Mechanics: Dissertations, Theses, and Student Research

Polycarbonate(PC), like most glassy polymers when undergoing large deformations exhibits a very complex thermo-mechanical response. We look at PC as a model glassy polymer and examine its response to changes in loading rate, loading direction and temperature. We show that plastic flow in compression is accompanied by a change in the elastic response of PC from isotropic to anisotropic. This provides the necessity to introduce a new modeling method that can capture these changes. A finite deformation plasticity like thermodynamically consistent model is developed to capture this and the observed rate and temperature dependence. For this modeling method, we need …

Towards Optimal Effort Distribution In Process Design Under Uncertainty, With Application To Education, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

In most application areas, we need to take care of several (reasonably independent) participants. For example, in controlling economics, we must make sure that all the economic regions prosper. In controlling environment, we want to guarantee that all the geographic regions have healthy environment. In education, we want to make sure that all the students learn all the needed knowledge and skills.

In real life, the amount of resources is limited, so we face the problem of "optimally" distributing these resources between different objects.

What is a reasonable way to formalize "optimally"? For each of the participants, preferences can be …

Checking Design Constraints At Run-Time Using Ocl And Aspectj, Yoonsik Cheon, Carmen Avila, Steve Roach, Cuauhtemoc Munoz

Departmental Technical Reports (CS)

Design decisions and constraints of a software system can be specified precisely using a formal notation such as the Object Constraint Language (OCL). However, they are not executable, and assuring the conformance of an implementation to its design is hard. The inability of expressing design constraints in an implementation and checking them at runtime invites, among others, the problem of design drift and corrosion. We propose runtime checks as a solution to mitigate this problem. The key idea of our approach is to translate design constraints written in a formal notation such as OCL into aspects that, when applied to …

Regularity Of Non-Characteristic Minimal Graphs In The Heisenberg Group ℍ1, Luca Capogna, Giovanna Citti, Maria Manfredini

Mathematics Sciences: Faculty Publications

Minimal surfaces in the sub-Riemannian Heisenberg group can be constructed by means of a Riemannian approximation scheme, as limit of Riemannian minimal surfaces. We study the regularity of Lipschitz, non-characteristic minimal surfaces which arise as such limits. Our main results are apriori estimates on the solutions of the approximating Riemannian PDE and the ensuing C∞ regularity of the sub-Riemannian minimal surface along its Legendrian foliation.

Taking Reasonable Doubt Seriously, Arnold H. Lowey

Chicago-Kent Law Review

In recent years, we have discovered a spate of factually innocent people who have been convicted. In this article, Professor Loewy contends that the failure of juries to take reasonable doubt seriously contributes to this phenomenon. Professor Loewy via an illustrative fictitious case explains that juries might be reluctant to give the defendant the benefit of a reasonable doubt because of their concern about putting dangerous criminals back on the street. He then asks whether we really want juries to take reasonable doubt seriously. Concluding that we do, he examines how we can do that. Loewy concludes that the best …

Spatial Distribution Of Petroleum Hydrocarbons In Sediment Cores From Blind Pass, St. Pete Beach, Florida, Charles M. Featherstone, John Proni, Thomas P. Carsey, Cheryl J. Brown, Madeleine M. Adler, Patricia Blackwelder, Husain Alsayegh, Teresa A. Hood, Christina Piela, Donald S. Mccorquodale Jr.

Marine & Environmental Sciences Faculty Reports

One hundred and one sediment cores were collected to characterize the spatial distribution of petroleum hydrocarbons within and just outside Blind Pass, St. Pete Beach, Florida. Twenty-five percent of the cores exhibited levels of petroleum hydrocarbons above detection limits of the gas chromatograph/flame ionization detector (GC/FID) (0.01 mg/Kg), but at generally low concentrations. Petroleum hydrocarbon speciation studies of these samples (gas chromatography/mass spectroscopy [GC/MS]) indicate above-detection level (1 μg/Kg) petroleum hydrocarbons are similar to the non-volatile petroleum hydrocarbons found in a Bouchard 155 reference sample collected after the 1993 oil spill in the area, but are in a much degraded …

Extraction And Analysis Of Coral Reef Core Samples From Broward County, Florida., Anastasios Stathakopoulos

HCNSO Student Theses and Dissertations

The reefs off Broward County exist as three shore-parallel, sequentially deeper terraces named the "inner", "middle", and "outer" reefs and also a shallower, nearshore ridge complex. These structures span the continental coast of southeast Florida from Palm Beach County to southern Miami-Dade County and were characterized as relict, early Holocene shelf-edge and mid-shelf reefs along with limestone ridges. Presently, the reefs are colonized by a fauna characteristic of West Atlantic/Caribbean reef systems. Scleractinian coral cover is low except for a few dense patches of Acropora cervicornis, while Acropora palmata is absent except for a few individual living colonies.

Angular Mobility Assisted Coverage In Directional Sensor Networks, Cyriac Kandoth, Sriram Chellappan

Computer Science Faculty Research & Creative Works

In this paper, we consider the issue of angular mobility assisted coverage enhancement in directional camera sensor networks. in our model, each sensor can visually capture (i.e. sense) events within a sector in its field of view and can also rotate about a fixed axis to enhance its coverage. the problem we particularly address is how to enhance blanket coverage leveraging angular mobility of the sensors in the network starting from an arbitrary initial deployment. the core idea of our algorithm, called the Face Away algorithm, is to use the known directions of neighboring sensors to find the direction with …

Self Powered Sensing By Combining Novel Sensor Architectures With Energy Harvesting, Vishwas Bedekar

Material Science and Engineering Dissertations - Archive

Recent advancements in the field of wireless sensor networks have resulted in increasing demand for self-powering techniques that reduces the dependence on batteries. In order to address this problem, there has been significant effort on generating small electrical power locally by harvesting energy from freely available environmental sources such as mechanical vibrations, wind, and stray magnetic field. Further, there is need for inventing new sensing techniques to reduce the overall power consumption. The road for reaching the destination of self-powered sensor networks requires cooperative progress in reduction in sensor power consumption by developing new sensing mechanisms and local generation of …
