A Model Of Precipitation Rates In Kentucky, 1965-1996, Kevin Cary
A Model Of Precipitation Rates In Kentucky, 1965-1996, Kevin Cary
Masters Theses & Specialist Projects
Hourly precipitation data from thirty cooperative stations in Kentucky from 1965 to 1996 were used to determine the diurnal distribution of precipitation rates. Descriptive summaries for the diurnal distribution for each climate division in Kentucky and for Kentucky as a whole were calculated. In each case, the trends were similar. Precipitation rates increased into the afternoon and then decreased until sunrise. A stochastic model was developed to estimate mean seasonal precipitation rates in Kentucky by using regional and localized parameters. More than half of the variation (r2 = 0.57) in precipitation rates can be explained by the following variables: 1) …

Burning And Burying In Connecticut: Are Regional Solutions To Solid Waste Disposal Equitable?, Timothy Black, John A. Stewart
Burning And Burying In Connecticut: Are Regional Solutions To Solid Waste Disposal Equitable?, Timothy Black, John A. Stewart
New England Journal of Public Policy
To comply with federal legislation, states throughout the country are replacing old town dumps with a regional system for municipal solid waste disposal.This system includes trash-to-energy incinerators and ash landfills as well as recycling and reduction facilities. While these new types of facilities are expected to be environmentally safer, they have concentrated the disposal process of waste generated throughout the state in fewer locations. State leaders champion the use of newer, cleaner disposal methods, while local community groups complain that they have become the dumping grounds for the state. This is the first environmental equity study to examine whether these …

Survivability Architecture For Workflow Management Systems, Jorge Cardoso, Zongwei Luo, John A. Miller, Amit P. Sheth, Krzysztof J. Kochut
Kno.e.sis Publications
The survivability of critical infrastructure systems has been gaining increasing concern from the industry. The survivability research area addresses the issue of infrastructure systems that continues to provide pre-established service levels to users in the face of disorders and react to changes in the surrounding environment. Workflow management systems need to be survivable since they are used to support critical and sensitive business processes. They require a high level of dependability and should not allow process instances to be interrupted or aborted due to failures. Moreover, due to their sensitivity, business process should reflect any change in the environment. In …
In-Cave Dye Tracing And Drainage Basin Divides In The Mammoth Cave Karst Aquifer, Kentucky, Chris Groves, Joe Meiman, Shannon Herstein
In-Cave Dye Tracing And Drainage Basin Divides In The Mammoth Cave Karst Aquifer, Kentucky, Chris Groves, Joe Meiman, Shannon Herstein
Earth, Environmental, and Atmospheric Sciences Faculty Publications
Karst ground-water basin divides are generally depicted as two-dimensional lines on maps, but they are better considered as three-dimensional surfaces within the subsurface. Dye traces are necessary to map out these surfaces and to locate conduits inaccessible to cave surveyors, and are indispensable for understanding the geometry of the complex networks of flow paths through the aquifer. A key reason why the Mammoth Cave System is the world's longest known cave is that its passages extend over several major ground-water basins. The divides between these basins define the drainage system geometry and precise location of them is critical for understanding …

Purpose: To examine the usefulness of three types of benchmarking for interpreting patient outcome data.
Design: This study was part of a multiyear, multihospital longitudinal survey of 10 patient outcomes. The patient outcome used for this methodologic presentation was central line infections (CLI). The sample included eight hospitals in an integrated healthcare system, with a range in size from 144 to 861 beds. The unit of analysis for CLI was the number of line days, with the CLI rate defined as the number of infections per 1,000 patient-line days per month.
Methods: Data on each outcome were collected at the …

A "Converse" Of The Banach Contraction Mapping Theorem, Pascal Hitzler, Anthony K. Seda
Computer Science and Engineering Faculty Publications
We prove a type of converse of the Banach contraction mapping theorem for metric spaces: if X is a T1 topological space and f: X -> X is a function with the unique fixed point a such that fn(x) converges to a for each x is a member of X, then there exists a distance function d on X such that f is a contraction on the complete ultrametric space (X,d) with contractivity factor 1/2. We explore properties of the resulting space (X,d).

Lessons From An Inventory Of The Ames, Iowa, Flora (1859-2000), William R. Norris, Deborah Q. Lewis, Mark P. Widrlechner, Jimmie D. Thompson, Richard O. Pope
Journal of the Iowa Academy of Science: JIAS
A botanical survey of the vascular flora of the "planning and zoning jurisdiction" of the city of Ames, Iowa (i.e., the area within a boundary 3.2 km beyond the current city limits) was compiled from 1990 to 2000. During this survey, 916 taxa (71 % native) were encountered within chis boundary. Literature reviews and a survey of Iowa State University's Ada Hayden Herbarium for specimens that had been collected in Ames since 1859 add 204 taxa to the flora. This total of 1,120 taxa exceeds the number of taxa known from any comparable area (including counties) in Iowa. We produced …

Unique Supported-Model Classes Of Logic Programs, Pascal Hitzler, Anthony K. Seda
Computer Science and Engineering Faculty Publications
We study classes of programs, herein called unique supported-model classes, with the property that each program in the class has a unique supported model. Elsewhere, the authors examined these classes from the point of view of operators defined relative to certain three-valued logics. In this paper, we complement our earlier results by considering how unique supported-model classes fit into the framework given by various classes of programs in several well-known approaches to semantics.

Thermoregulation In Juvenile Red Kangaroos (Macropus Rufus) After Pouch Exit: Higher Metabolism And Evaporative Water Requirements, Adam J. Munn, Terence J. Dawson
Faculty of Science - Papers (Archive)
The population dynamics of red kangaroos (Macropus rufus) in the Australian arid zone is tightly linked with environmental factors, which partly operate via the survival of juvenile animals. A crucial stage is the young-at-foot (YAF) stage when kangaroos permanently exit the pouch. We have examined the thermal biology of YAF red kangaroos during ages from permanent pouch exit until weaning. Over a wide range of environmental temperatures (ambient temperature [T-a] -5 degrees to 45 degreesC), YAF red kangaroos had a mass-specific metabolism that was generally twice that of adults, considerably higher than would be expected for an adult marsupial of …

P2X(7) receptor is a ligand-gated cation-selective channel that mediates ATP-induced apoptosis of cells of the immune system. We and others have shown that P2X(7) is nonfunctional both in lymphocytes and monocytes from some subjects. To study a possible genetic basis we sequenced DNA coding for the carboxyl-terminal tail of P2X(7). In 9 of 45 normal subjects a heterozygous nucleotide substitution (1513A-->C) was found, whereas 1 subject carried the homozygous substitution that codes for glutamic acid to alanine at amino acid position 496. Surface expression of P2X(7) on lymphocytes was not affected by this E496A polymorphism, demonstrated both by confocal …

On The Evolution Of Probability-Weighting Function And Its Impact On Gambling, Steven Li, Yun Hsing Cheung
On The Evolution Of Probability-Weighting Function And Its Impact On Gambling, Steven Li, Yun Hsing Cheung
Research outputs pre 2011
It is well known that individuals treat losses and gains differently and there exists non-linearity in probability. The asymmetry between gains and losses is highlighted by the reflection effect. The non-linearity in probability is described by the curvature of the probability-weighting function. This paper studies the evolution of the probability-weighting function. It is assumed that the probability weighting for an individual follows a mean-reverting stochastic process. The Monte Carlo simulation technique is employed to study the evolution of the weighting function. The evolution of the probability- weighting function implies that an individual does not treat gains or losses consistently over …
Isolated Ramp Metering Feedback Control Utilizing Mixed Sensitivity For Desired Mainline Density And The Ramp Queues, Pushkin Kachroo, Kaan Ozbay, Donald E. Grove
Isolated Ramp Metering Feedback Control Utilizing Mixed Sensitivity For Desired Mainline Density And The Ramp Queues, Pushkin Kachroo, Kaan Ozbay, Donald E. Grove
Electrical & Computer Engineering Faculty Research
This paper presents a feedback control design for isolated ramp metering control. This feedback control design, unlike the existing isolated feedback ramp controllers, also takes into account the ramp queue length. Using a nonlinear H∞ control design methodology, we formulate the problem in the desired setting to be able to utilize the results of the methodology.

The Obispeno Chumash Indians: San Luis Obispo County's First Environmentalists, Sharon L. Marks
Theses Digitization Project
The primary focus of this project is with the interaction between nature and people. How did the Obispeno Chumash affect their surroundings and what was the outcome? Did changes occur in the environment when other people took over the care of the land? Over the last 250 years, the Obispeno Chumash land has evolved from an ecologically green dominion under their stewardship to the present day where the area is noted for its mission, recreational value, wealth of opportunity, and a nuclear power plant located between Morro Bay and Point Buchon along the ocean.
Latent Maximum Entropy Principle For Statistical Language Modeling, Shaojun Wang, Ronald Rosenfeld, Yunxin Zhao
Latent Maximum Entropy Principle For Statistical Language Modeling, Shaojun Wang, Ronald Rosenfeld, Yunxin Zhao
Kno.e.sis Publications
We describe a unified probabilistic framework for statistical language modeling, the latent maximum entropy principle. The salient feature of this approach is that the hidden causal hierarchical dependency structure can be encoded into the statistical model in a principled way by mixtures of exponential families with a rich expressive power. We first show the problem formulation, solution, and certain convergence properties. We then describe how to use this machine learning technique to model various aspects of natural language, such as syntactic structure of sentences, semantic information in a document. Finally, we draw a conclusion and point out future research directions.

Detection Of P2x Purinergic Receptors On Human B Lymphocytes, Ronald Sluyter, J A. Barden, James Wiley
Faculty of Science - Papers (Archive)
B lymphocytes are known to synthesise the P2X(7) subtype of the P2X purinergic receptor family; however, the identification of the other six P2X subtypes on these cells has been limited by the absence of specific antibodies. In this study, we used a panel of anti-P2X polyclonal antibodies and confocal microscopy to examine the presence of each P2X receptor on human B lymphocytes. We observed that P2X(1), P2X(2), P2X(4) and P2X(7) subtypes, but not P2X(3), P2X(5) and P2X(6) subtypes, are present on B lymphocytes.

During the course of this work, three different approaches to the formation of conducting polymer/carbon nanotube (CP/CNT) composites were investigated. The first approach involved the preparation of CNT dispersions using Poly methoxy aniline-5-sulfonic acid (PMAS) as a stabilizer. The second approach investigated involved the use of CNT as the dopant in the electropolymerization of CPs. The third approach involved the electrochemical deposition of a thin polymer film onto the surface of CNT paper. These CNT/CP composites were characterized to determine capacitance, conductivity and mechanical strength.
