Technology As The Representative Anecdote In Popular Discourses Of Health And Medicine, Lynn M. Harter, Phyllis Japp Jan 2001

Technology As The Representative Anecdote In Popular Discourses Of Health And Medicine, Lynn M. Harter, Phyllis Japp

Department of Communication Studies: Faculty Publications

Using a Burkean framework (1969), this article approaches medical dramas as cultural texts to be read for dominant meanings of health and health care. Burke’s representative anecdote illuminates the melding of science, technology, and healing in popular discourses of health, establishing technological intervention as the norm and marginalizing nontechnological (i.e., alternative) forms of health care. Popular entertainment reinforces this anecdote in narratives of healing as technological competence triumphing over nature.

A Generator Of Random Instances Of Binary Finite Constraint Satisfaction Problems With Controllable Levels Of Interchangeability, Hui Zou, Amy Beckwith, Berthe Y. Choueiry Jan 2001

A Generator Of Random Instances Of Binary Finite Constraint Satisfaction Problems With Controllable Levels Of Interchangeability, Hui Zou, Amy Beckwith, Berthe Y. Choueiry

School of Computing: Technical Reports

In order to test the performance of algorithms for solving Constraint Satisfaction Problems (CSPs), we must establish a large collection of CSP instances that meet a given set of specifications, such as the number of variables, domain size, constraint density, tightness, etc. The goal of this report is to describe a generator of instances that have a specified degree of interchangeability. An example of such a generator is described in (Freuder and Sabin 1997), which generates non-reflexive constraints and does not allow us to control concurrently the degree of interchangeability and tightness. We have developed a technique and written a …

Optimization Of Orthogonal Polyphase Spreading Sequences For Wireless Data Applications, B. J. Wysocki, Tadeusz Wysocki Jan 2001

Optimization Of Orthogonal Polyphase Spreading Sequences For Wireless Data Applications, B. J. Wysocki, Tadeusz Wysocki

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)

In this paper, we propose a simple but efficient method for optimizing correlation properties of polyphase spreading sequences for asynchronous DS CDMA applications. The proposed method can be used to minimize the mean square value of aperiodic crosscorrelation or the mean square value of aperiodic autocorrelation, the maximum value of aperiodic crosscorrelation functions, merit factor or other properties of the sequence set. The important feature of the method is that when applied to orthogonal sequences, it modifies correlation properties of the sequence set, while preserves their orthogonality for perfect synchronization.

Infrastructure Support For Controlled Experimentation With Software Testing And Regression Testing Techniques, Hyunsook Do, Sebastian Elbaum, Gregg Rothermel Jan 2001

Infrastructure Support For Controlled Experimentation With Software Testing And Regression Testing Techniques, Hyunsook Do, Sebastian Elbaum, Gregg Rothermel

School of Computing: Technical Reports

Where the creation, understanding, and assessment of software testing and regression testing techniques are concerned, controlled experimentation is an indispensable research methodology. Obtaining the infrastructure necessary to support such experimentation, however, is difficult and expensive. As a result, progress in experimentation with testing techniques has been slow, and empirical data on the costs and effectiveness of techniques remains relatively scarce. To help address this problem, we have been designing and constructing infrastructure to support controlled experimentation with testing and regression testing techniques. This paper reports on the challenges faced by researchers experimenting with testing techniques, including those that inform the …

Hierarchical Ring Network Configuration And Performance Modeling, V. Carl Hamacher, Hong Jiang Jan 2001

Hierarchical Ring Network Configuration And Performance Modeling, V. Carl Hamacher, Hong Jiang

School of Computing: Faculty Publications

Approximate analytical queuing network models for expected message packet delay in 2-level and 3-level hierarchical ring interconnection networks (INs) are developed. A major class of traffic carried by these INs consists of cache line transfers between processor caches and remote memory modules in shared-memory multiprocessors. Such traffic consists of short, fixed-length messages; they can be conveniently transported by the slotted-ring transmission technique which is studied here. The packet delay results derived from the models are shown to be quite accurate when checked against a simulation study. As well as facilitating analysis, the analytical models can be used to determine optimal …

Hierarchy-Based Access Control In Distributed Environments, Jean-Camille Birget, Xukai Zou, Guevara Noubir, Byrav Ramamurthy Jan 2001

Hierarchy-Based Access Control In Distributed Environments, Jean-Camille Birget, Xukai Zou, Guevara Noubir, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

Access control is a fundamental concern in any system that manages resources, e.g., operating systems, file systems, databases and communications systems. The problem we address is how to specify, enforce, and implement access control in distributed environments. This problem occurs in many applications such as management of distributed project resources, e-newspaper and payTV subscription services.

Starting from an access relation between users and resources, we derive a user hierarchy, a resource hierarchy, and a unified hierarchy. The unified hierarchy is then used to specify the access relation in a way that is compact and that allows efficient queries. It is …

The Effects Of Multitasking On Quality Inspection In Advanced Manufacturing Systems, Jose A. Pesante, Robert C. Williges, Jeffrey C. Woldstad Jan 2001

The Effects Of Multitasking On Quality Inspection In Advanced Manufacturing Systems, Jose A. Pesante, Robert C. Williges, Jeffrey C. Woldstad

Department of Industrial and Management Systems Engineering: Faculty Publications

Although the industrial quality inspection task has been extensively studied, the effect of multitasking on the performance of the operator in a hybrid inspection system is still unknown. The experiment described in this article compared the quality inspection performance for participants performing a single task, 3 multiple tasks, and 5 multiple tasks. The results of this research indicate that the performance of the operator in the quality inspection task while multitasking in an advanced manufacturing system will be determined by the interaction between the number of different types of defects that can be presented at the same time in the …

A Direct Correlation Function For Mesomorphic Polymers And Its Application To The ‘Smectic’ Phase Of Isotactic Polypropylene, Y Cohen, Ravi F. Saraf Jan 2001

A Direct Correlation Function For Mesomorphic Polymers And Its Application To The ‘Smectic’ Phase Of Isotactic Polypropylene, Y Cohen, Ravi F. Saraf

Papers in Materials Science

A general model to calculate the structure of a smectic to nematic-like order in polymer systems is proposed. The model is limited to well-aligned molecules with respect to each other. It is especially suited for systems where the packing between neighboring chains is described by liquid-like disorder with axial registration in the chain-axis direction. In such a case the diffraction pattern from the oriented structure exhibits broad liquid-like reflections on the equatorial but sharper reflections on the layer lines. An Ornstein-Zernike approach is adopted to calculate the inter-chain packing and inter-chain registration, where the direct correlation function of packing and …

Relationship Between Durophagy And Feeding Biomechanics In Gray Triggerfish, Balistes Capriscus: Intraspecific Variation In Ecological Morphology, Christopher J. Durie, Ralph G. Turingan Jan 2001

Relationship Between Durophagy And Feeding Biomechanics In Gray Triggerfish, Balistes Capriscus: Intraspecific Variation In Ecological Morphology, Christopher J. Durie, Ralph G. Turingan

Ocean Engineering and Marine Sciences Faculty Publications

The relationship between oral jaw biomechanics and consumption of hard prey was compared between Gulf of Mexico (Gulf) and Atlantic Ocean (Atlantic) populations of gray triggerfish (Balistes capriscus) to examine intraspecific ecomorphological variation between these fish. Gut content analysis revealed that Atlantic fish fed more on hard-shelled invertebrates, such as crabs and sea urchins, than Gulf conspecifics. Difference in the relative magnitude of durophagy between Gulf and Atlantic triggerfish was associated with intraspecific differences in key biomechanical properties of the prey-capture and processing mechanism. The more durophagous Atlantic B. capriscus had more massive jaw bones and muscles than Gulf fish. …

The Economic Case For Labor Standards: A Layman’S Guide, Thomas I. Palley Jan 2001

The Economic Case For Labor Standards: A Layman’S Guide, Thomas I. Palley

Richmond Journal of Global Law & Business

The place of labor standards in the global economy has figured prominently in recent discussions of trade and globalization. Labor standards figured prominently in the Seattle meeting of the World Trade Organization (WTO) in 1999, and they promise to figure prominently in discussions about a proposed Free Trade Area of Americas (FTAA). Labor standards represent a critical issue for both the American labor movement and the international trade union movement as they are central to making globalization work for working people.

Campaign Of Sabotage: Big Government's War Against Public Transportation, Michael Lewyn Jan 2001

Campaign Of Sabotage: Big Government's War Against Public Transportation, Michael Lewyn

Scholarly Works

Historically, American politicians have been far more generous to highways than to public transit. The political elite's failure to support public transit is based on the view that despite decades of state and federal support, transit ridership has dwindled. This article criticizes that theory, by explaining that far from promoting public transit, government at all levels has sabotaged transit in a variety of ways: by building highways to suburbs unserved by public transit, by loading down transit systems with unfunded mandates, by using housing, education and tax policy to encourage migration to those suburbs, and by using zoning policy to …

Modeling And Fabrication Of Lightweight, Deformable Mirrors Subjected To Discrete Loading, Michael E. Roche Jan 2001

Modeling And Fabrication Of Lightweight, Deformable Mirrors Subjected To Discrete Loading, Michael E. Roche

University of Kentucky Master's Theses

The push towards larger diameter space telescope mirrors has caused the space industry to look at lightweight, deformable alternatives to the traditional monolithic mirror. One possible solution to the dilemma is to use the piezoelectric properties of certain materials to create a lightweight, deformable mirror. Current piezoelectric deformable mirror designs use individual actuators, creating an immensely complex system as the mirrors increase in size. The objective of this thesis is to aid in the design and development of lightweight, deformable mirrors for use in space based telescopes. Two topics are considered to aid this development. A doubly curved, lightweight, bimorph …

Risk Based Urban Watershed Management Under Conflicting Objectives, Vladimir Novotny, David E. Clark, Robert J. Griffin, Douglas Booth Jan 2001

Risk Based Urban Watershed Management Under Conflicting Objectives, Vladimir Novotny, David E. Clark, Robert J. Griffin, Douglas Booth

Economics Faculty Research and Publications

Ecological impairment and flooding caused by urbanization can be expressed numerically by calculating the risks throughout the watershed (floodplain) and along the main stems of the streams. The risks can be evaluated in terms of the present and/or future. This article describes the methodologies for ascertaining the risks in the Geographical Information Systems (GIS) environment. The objectives of urban flood controls and ecological preservation/restoration of urban waters are often conflicting and, in the past, the sole emphasis on flood control led to destruction of habitat and deterioration of water quality. An optimal solution to these two problems may be achieved …

Porosity, Percolation Thresholds, And Water Retention Behavior Of Random Fractal Porous Media, Michael C. Sukop Jan 2001

Porosity, Percolation Thresholds, And Water Retention Behavior Of Random Fractal Porous Media, Michael C. Sukop

University of Kentucky Doctoral Dissertations

Fractals are a relatively recent development in mathematics that show promise as a foundation for models of complex systems like natural porous media. One important issue that has not been thoroughly explored is the affect of different algorithms commonly used to generate random fractal porous media on their properties and processes within them. The heterogeneous method can lead to large, uncontrolled variations in porosity. It is proposed that use of the homogeneous algorithm might lead to more reproducible applications. Computer codes that will make it easier for researchers to experiment with fractal models are provided. In Chapter 2, the application …

The Sex Discrimination Argument In Gay Rights Cases, Nan D. Hunter Jan 2001

The Sex Discrimination Argument In Gay Rights Cases, Nan D. Hunter

Georgetown Law Faculty Publications and Other Works

The argument that laws that discriminate on the basis of sexual orientation in fact discriminate on the basis of sex is not new. Advocates have been pressing this claim for almost thirty years. Simply put, the argument is that a statute that bars a sexual relationship between two women or two men discriminates on the basis of sex because either partner could have had the same relationship with a person of the opposite sex.

Automatic Image To Model Alignment For Photo-Realistic Urban Model Reconstruction, Mike Partington Jan 2001

Automatic Image To Model Alignment For Photo-Realistic Urban Model Reconstruction, Mike Partington

University of Kentucky Master's Theses

We introduce a hybrid approach in which images of an urban scene are automatically alignedwith a base geometry of the scene to determine model-relative external camera parameters. Thealgorithm takes as input a model of the scene and images with approximate external cameraparameters and aligns the images to the model by extracting the facades from the images andaligning the facades with the model by minimizing over a multivariate objective function. Theresulting image-pose pairs can be used to render photo-realistic views of the model via texturemapping.Several natural extensions to the base hybrid reconstruction technique are also introduced. Theseextensions, which include vanishing point …

Shadow Generation Based On Re Loops And Their Angular Representations, Khageshwar Thakur Jan 2001

Shadow Generation Based On Re Loops And Their Angular Representations, Khageshwar Thakur

University of Kentucky Master's Theses

The initial attempt was to find efficient technique to identify shadow plylgons in the shadow-volume based shadow generation algorithm. It was observed that shadows correspond to loops of ridge edges (REs). By identifying all the non-overlapping RE loops of a 3D object, one finds all the shadow polygons and, consequently, all the shadows it generates on other objects as well as shadows it generates on itself. This, however, requires extensive edge-edge intersection tests.It was subsequently realized that by storing the angular representations of the RE looks in a look up table, one can avoid the need of decomposing RE loops …

Piv Measurements Of Channel Flow With Multiple Rib Arrangements, Harald Roclawski Jan 2001

Piv Measurements Of Channel Flow With Multiple Rib Arrangements, Harald Roclawski

University of Kentucky Master's Theses

A model of a gas turbine blade cooling channel equipped with turbulators and a backward facing step geometry was examined. Up to four turbulators oriented cross-stream and inclined 45° to the flow direction were mounted in the channel. The blockage ratio b/H of the turbulators and the height h/H of the backward facing step was 0:125 and 0:14 respectively. The number of turbulators as well as their size was varied. In a preliminary investigation, hot-wire and pressure measurements were taken for three different Reynolds numbers (5,000, 12,000, 18,000)in the center plane of the test section. Subsequently, particle image …
