Enforcement, Economics And Estimates, Peter K. Yu Jan 2010

Enforcement, Economics And Estimates, Peter K. Yu

Faculty Scholarship

This article focuses on intellectual property enforcement, a topic that is of great importance to both developed and less developed countries. It begins by refuting the simple, and often politically motivated, claim that many countries fail to provide effective intellectual property enforcement by virtue of their lack of political will. Drawing on the latest economic literature, this article shows that high enforcement standards come with a hefty price tag and difficult trade-offs.

The article then outlines the challenges in measuring the cross-border economic impact of piracy and counterfeiting. As an illustration, the article discusses the ongoing effort by the US …


High-Strength Selfconsolidating Concrete Girders Subjected To Elevated Compressive Fiber Stresses, Part 1: Prestress Loss And Camber Behavior, Jared E. Brewe, John J. Myers Jan 2010

High-Strength Selfconsolidating Concrete Girders Subjected To Elevated Compressive Fiber Stresses, Part 1: Prestress Loss And Camber Behavior, Jared E. Brewe, John J. Myers

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The design of prestressed concrete members is restricted by the requirement that the extreme compressive fiber stress at midspan of simply supported members be less than 60% of the concrete compressive strength at release of prestressing. the purported purpose of this limit is to address serviceability performance, but it places unnecessary limits on the capability of the materials. for this research program, six prestressed concrete girders were produced with high-strength self-consolidating concrete and subjected to compressive fiber stress levels ranging from 65% to 84% of the concrete compressive strength at release of prestressing. Time dependent concrete surface strains were measured …


Automatic Object Detection And Tracking In Video, Isaac Case Jan 2010

Automatic Object Detection And Tracking In Video, Isaac Case

Theses

One ability of the human visual system is the ability to identify and track moving objects. Examples of this can easily be seen in any sporting event. Humans are able to find an object in motion and track its current path and even predict a trajectory based on its current motion. Computer vision systems exist that are able to track an object in video, but usually these systems need to be instructed what the object to track is. As a way to further the work done by these computer vision systems, I present two additions to the work in the …


Segmentation Of Slap Fingerprints, Derek Johnson Jan 2010

Segmentation Of Slap Fingerprints, Derek Johnson

Theses

This thesis describes a novel algorithm that segments the individual fingerprints in a multi-print image. The algorithm identifies the distal phalanx portion of each finger that appears in the image and labels them as an index, middle, little or ring finger. The accuracy of this algorithm is compared with the publicly-available reference implementation, NFSEG, part of the NIST Biometric Image Software (NBIS) suite developed at National Institute of Standards and Technology (NIST). The comparison is performed over large set of fingerprint images captured from unique individuals.


Scene Classification Using Spatial Pyramid Matching And Hierarchical Dirichlet Processes, Haohui Yin Jan 2010

Scene Classification Using Spatial Pyramid Matching And Hierarchical Dirichlet Processes, Haohui Yin

Theses

The goal of scene classification is to automatically assign a scene image to a semantic category (i.e. "building" or "river") based on analyzing the visual contents of this image. This is a challenging problem due to the scene images' variability, ambiguity, and a wide range of illumination or scale conditions that may apply. On the contrary, it is a fundamental problem in computer vision and can be used to guide other processes such as image browsing, contentbased image retrieval and object recognition by providing contextual information. This thesis implemented two scene classification systems: one is based on Spatial Pyramid Matching …


Effect Of Radar-Rainfall Uncertainties On The Spatial Characterization Of Rainfall Events, Pradeep V. Mandapaka, Gabriele Villarini, Bong Chul Seo, Witold F. Krajewski Jan 2010

Effect Of Radar-Rainfall Uncertainties On The Spatial Characterization Of Rainfall Events, Pradeep V. Mandapaka, Gabriele Villarini, Bong Chul Seo, Witold F. Krajewski

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Remotely sensed precipitation products, due to their large areal coverage and high resolution, have been widely used to provide information on the spatiotemporal structure of rainfall. However, it is well known that these precipitation products also suffer from large uncertainties that originate from various sources. In this study, we selected radar-rainfall (RR) data corresponding to 10 warm season events over a 256 x 256 km2 domain with a data resolution of 4 x 4 km2 in space and 1 h in time. We characterized their spatial structure using correlation function, power spectrum, and moment scaling function. We then …


Assessing The Argument For Specialized Courts: Evidence From Family Courts In Spain, Nuno Garoupa, Natalia Jorgensen, Pablo Vazquez Jan 2010

Assessing The Argument For Specialized Courts: Evidence From Family Courts In Spain, Nuno Garoupa, Natalia Jorgensen, Pablo Vazquez

Faculty Scholarship

Specialized courts have become a key component of the legal reform packages implemented in civil law countries, particularly, in the area of family law. One argument for this policy is that they are able to reach a decision faster than the regular courts, which are normally congested. We use data from a survey of Spanish family courts in the region of Madrid to test this claim. After controlling for other relevant variables, the econometric results did not provide strong support for specialized courts.


Legislatures, Judges, And Parole Boards: The Allocations Of Discretion Under Determinate Sentencing, Dhammika Dharmapala, Nuno Garoupa, Joanna M. Shepherd Jan 2010

Legislatures, Judges, And Parole Boards: The Allocations Of Discretion Under Determinate Sentencing, Dhammika Dharmapala, Nuno Garoupa, Joanna M. Shepherd

Faculty Scholarship

The most significant development in criminal sentencing in recent decades has been the shift from indeterminate to determinate sentencing. Yet no study has systematically explored the factors leading to this shift. In this Article, we provide the first analysis to explain why state legislatures enact reforms that significantly reduce both judges' and parole boards' discretion over criminal sentencing. First, we develop a political economy model that explains why legislatures acting in their own self-interest may be motivated to enact these laws. Our model predicts that legislatures are more likely to enact determinate sentencing reforms when there is tension among the …


Forced Sale Risk: Class, Race, And The "Double Discount", Thomas W. Mitchell, Stephen Malpezzi, Richard K. Green Jan 2010

Forced Sale Risk: Class, Race, And The "Double Discount", Thomas W. Mitchell, Stephen Malpezzi, Richard K. Green

Faculty Scholarship

What impact does a forced sale have upon a property owner's wealth? And do certain characteristics of a property owner such as whether they are rich or poor or whether they are black or white, tend to affect the price yielded at a forced sale? This Article addresses arguments made by some courts and legal scholars who have claimed that certain types of forced sales result in wealth maximizing, economic efficiencies. The Article addresses such economic arguments by returning to first principles and reviewing the distinction between sales conducted under fair market value conditions and sales conducted under forced sale …

Space Age Love Song: The Mix Tape In A Digital Universe, Megan M. Carpenter Jan 2010

Space Age Love Song: The Mix Tape In A Digital Universe, Megan M. Carpenter

Faculty Scholarship

Mix tapes are the classic, iconic form of music sharing. Mix tape creators of the past believed they were making a piece of art larger than the sum of its parts. And even in the face of technological development so rapid and far-reaching as to remove the literal "tape" from "mix tape," there are nonetheless modem incarnations that crop up on a regular basis, from mix CDs to mix-sharing websites. The technology is different, but the song remains the same.


State Liability, Giuseppe Dari-Mattiacci, Nuno Garoupa, Fernando Gomez-Pomar Jan 2010

State Liability, Giuseppe Dari-Mattiacci, Nuno Garoupa, Fernando Gomez-Pomar

Faculty Scholarship

Should states be liable towards individuals for failure to provide justice, good roads, or timely administrative decisions? In this article, we show that state liability can serve three different purposes, none of which implies that the state should be liable in tort, unless other specific conditions are met. One purpose is to provide incentives for state agencies and private individuals to act efficiently. Here, the effectiveness of liability depends on the channelling of incentives down the chain of command to the acting state employee. The second purpose of state liability is to remove incentives for private parties, when these incentives …


Dynamic Fault Tolerant Grid Workflow In The Water Threat Management Project, Young Suk Moon Jan 2010

Dynamic Fault Tolerant Grid Workflow In The Water Threat Management Project, Young Suk Moon

Theses

Achieving fault tolerance is an inevitable problem in distributed systems, with it becoming more challenging in decentralized, heterogeneous, and dynamic-environment systems such as a Grid. When deploying applications requires time-criticality, how to allocate resources for jobs in a fault-tolerant manner is an important issue for the delivery of the services. The Water Threat Management project is a research to find solutions for the contamination incidents problems in urban water distribution systems, and it involves the development of the cyberinfrastructure in a Grid environment. To handle such urgent events properly, the deployment of the system demands real-time processing without the failure. …


Necessity Of Implementing Electronic Personal Health Information Privacy Regulation In Dominican Republic, Miguel Molina Jan 2010

Necessity Of Implementing Electronic Personal Health Information Privacy Regulation In Dominican Republic, Miguel Molina

Theses

The use of technology has increased considerably in the Dominican Republic in the past years. All public and private organizations have started a process of digitize all information they manage. The health area is not away from this process and hence they have started to use personal health records in a digital format. However, the management given to this information is not regulated by any law in the DR. Doctors, medical centers, health assurance companies and patients treat this data as they want without any control which represents a huge privacy risk for patients in the country. During our investigation …


How Does The Power Crisis Problem Affect Data Management In The Dominican Republic, José Raúl Vélez Díaz Jan 2010

How Does The Power Crisis Problem Affect Data Management In The Dominican Republic, José Raúl Vélez Díaz

Theses

In the last decade, the Dominican Republic has been affected by a power crisis nation wide. In 2008, the crisis reached a deficit of 40% in the generation of power; and the problem seems to go on as no agreement is executed to solve it. The problem is originated from the lack of efficiency of many generators, and debts with the generators companies. An important aspect of the power crisis is the challenge to provide power quality to electronic equipment. Data management can be affected by this problem whenever there is data corruption or lost, and devices are damaged. Data …

Control Of Self-Reconfigurable Robot Teams For Sensor Placement, Jacob Hays Jan 2010

Control Of Self-Reconfigurable Robot Teams For Sensor Placement, Jacob Hays

Theses

"Self Reconfigurable Robots (SRRs) are a system of many simple modules that can rearrange themselves to work together and better perform complicated tasks. They are in theory more extensible then traditional robotics. We investigate the particular problem of using SRRs to both explore and survey an unknown environment. The environment is explored by using the Robots internal sensors, and surveyed by placing a limited number of static sensors at ideal locations. The advantage of SRRs is that they can adapt to terrain difficulty by adjusting the number of individual robots on the field by reorganizing its modules. We test a …


Efficient Object Tracking In Waas Data Streams, Trevor Clarke Jan 2010

Efficient Object Tracking In Waas Data Streams, Trevor Clarke

Theses

Wide area airborne surveillance (WAAS) systems are a new class of remote sensing imagers which have many military and civilian applications. These systems are characterized by long loiter times (extended imaging time over fixed target areas) and large footprint target areas. These characteristics complicate moving object detection and tracking due to the large image size and high number of moving objects. This thesis evaluates existing object detection and tracking algorithms with WAAS data and provides enhancements to the processing chain which decrease processing time and increase tracking accuracy. Decreases in processing time are needed to perform real-time or near real-time …


Threshold Interval Indexing Techniques For Complicated Uncertain Data, Andrew Knight Jan 2010

Threshold Interval Indexing Techniques For Complicated Uncertain Data, Andrew Knight

Theses

Uncertain data is an increasingly prevalent topic in database research, given the advance of instruments which inherently generate uncertainty in their data. In particular, the problem of indexing uncertain data for range queries has received considerable attention. To efficiently process range queries, existing approaches mainly focus on reducing the number of disk I/Os. However, due to the inherent complexity of uncertain data, processing a range query may incur high computational cost in addition to the I/O cost. In this paper, I present a novel indexing strategy focusing on one-dimensional uncertain continuous data, called threshold interval indexing. Threshold interval indexing is …


Developing A Taxonomy For Office Email: A Case Study, Larry Conrow Jan 2010

Developing A Taxonomy For Office Email: A Case Study, Larry Conrow

Theses

Email is the most successful computer application invented yet. As email communication continues to thrive professionals are running into similar problems time and time again. Email overload has been estimated to be costing a loss of productivity in the U.S. of millions or even billions of dollars due to time spent reading, organizing and saving emails. As stated in New York Times in 2007 by Steve Lohr, "$650 billion figure is an estimate of the cost of unnecessary interruptions in terms of lost productivity and innovation". These interruptions which add to the information overload problems is a total of several …


Multigrid In A Weighted Space Arising From Axisymmetric Electromagnetics, Dylan M. Copeland, Jay Gopalakrishnan, Minah Oh Jan 2010

Multigrid In A Weighted Space Arising From Axisymmetric Electromagnetics, Dylan M. Copeland, Jay Gopalakrishnan, Minah Oh

Mathematics and Statistics Faculty Publications and Presentations

Consider the space of two-dimensional vector functions whose components and curl are square integrable with respect to the degenerate weight given by the radial variable. This space arises naturally when modeling electromagnetic problems under axial symmetry and performing a dimension reduction via cylindrical coordinates. We prove that if the original three-dimensional domain is convex then the multigrid Vcycle applied to the inner product in this space converges, provided certain modern smoothers are used. For the convergence analysis, we first prove several intermediate results, e.g., the approximation properties of a commuting projector in weighted norms, and a superconvergence estimate for a …


Phase-Linking And The Perceived Motion During Off-Vertical Axis Rotation, Jan Holly, Scott Wood, Gin Mccollum Jan 2010

Phase-Linking And The Perceived Motion During Off-Vertical Axis Rotation, Jan Holly, Scott Wood, Gin Mccollum

Mathematics and Statistics Faculty Publications and Presentations

Human off-vertical axis rotation (OVAR) in the dark typically produces perceived motion about a cone, the amplitude of which changes as a function of frequency. This perception is commonly attributed to the fact that both the OVAR and the conical motion have a gravity vector that rotates about the subject. Little-known, however, is that this rotating-gravity explanation for perceived conical motion is inconsistent with basic observations about self-motion perception: (a) that the perceived vertical moves toward alignment with the gravito-inertial acceleration (GIA) and (b) that perceived translation arises from perceived linear acceleration, as derived from the portion of the GIA …


Prudentialism In Mcdonald V. City Of Chicago, Neil S. Siegel Jan 2010

Prudentialism In Mcdonald V. City Of Chicago, Neil S. Siegel

Faculty Scholarship

At least two kinds of prudential argument have been identified in the literature on constitutional interpretation: court-centered prudentialism and system-centered prudentialism. Commentators often characterize court-centered prudentialism as animated by concern over the Supreme Court’s preservation of its public legitimacy, which can be undermined when the Justices decide controversial questions in ways that cause backlash. By contrast, system-centered prudentialism asks not only what judicial decision is best for the Court’s effectiveness, but also what response is best for the constitutional system as a whole when the Court’s legitimacy is not at stake.

The Court’s recent decision in McDonald v. City of …


A Coase Theorem For Constitutional Theory, Neil S. Siegel Jan 2010

A Coase Theorem For Constitutional Theory, Neil S. Siegel

Faculty Scholarship

There is much to admire about Barry Friedman’s new book, The Will of the People. Explaining how the institution of judicial review was made safe for democracy in America, Friedman’s story is extensively researched, beautifully written, scrupulously nonpartisan about the modern Court, and frequently humorous. What is more, his primary claim - that the Supreme Court of the United States is very much a democratic institution because judicial review always has been responsive to public opinion - is, to a large extent, convincing. I have taught The Will of the People in my first-year constitutional law course, and I plan …


Influence Of Interactions Between Turbulence And Radiation On Transmissivities In Hypersonic Turbulent Boundary Layers, A. M. Feldick, L. (Lian) Duan, M. F. Modest, M. P. Martín, D. A. Levin Jan 2010

Influence Of Interactions Between Turbulence And Radiation On Transmissivities In Hypersonic Turbulent Boundary Layers, A. M. Feldick, L. (Lian) Duan, M. F. Modest, M. P. Martín, D. A. Levin

Mechanical and Aerospace Engineering Faculty Research & Creative Works

In the current paper, a high-fidelity large eddy simulation solver is coupled to our modified line-by-line radiative transport equation solver to study the effects of absorption turbulence-radiation interations in a hypersonic turbulent boundary layer, representative of the Orion CEV entering Earth's atmosphere, at peak heating condition. The turbulent and radiation fields represent extreme conditions typical of Orion, as the simulated boundary layer represents the region of high turbulence coupled to region of highest incident radiation. A simplification in the calculation of molecular spectra with a single temperature property database in allows for tractable calculation of spectral properties. A comparison of …


Direct Numerical Simulation Of Hypersonic Turbulent Boundary Layers. Part 2. Effect Of Wall Temperature, L. (Lian) Duan, I. Beekman, M. P. Martín Jan 2010

Direct Numerical Simulation Of Hypersonic Turbulent Boundary Layers. Part 2. Effect Of Wall Temperature, L. (Lian) Duan, I. Beekman, M. P. Martín

Mechanical and Aerospace Engineering Faculty Research & Creative Works

In this paper, we perform direct numerical simulation (DNS) of turbulent boundary layers at Mach 5 with the ratio of wall-to-edge temperature T w/T ℘ from 1.0 to 5.4 (Cases M5T1 to M5T5). The influence of wall cooling on Morkovin's scaling, Walz's equation, the standard and modified strong Reynolds analogies, turbulent kinetic energy budgets, compressibility effects and near-wall coherent structures is assessed. We find that many of the scaling relations used to express adiabatic compressible boundary-layer statistics in terms of incompressible boundary layers also hold for non-adiabatic cases. Compressibility effects are enhanced by wall cooling but remain insignificant, and the …


Audio Scene Segementation Using A Microphone Array And Auditory Features, Harikrishnan Unnikrishnan Jan 2010

Audio Scene Segementation Using A Microphone Array And Auditory Features, Harikrishnan Unnikrishnan

University of Kentucky Master's Theses

Auditory stream denotes the abstract effect a source creates in the mind of the listener. An auditory scene consists of many streams, which the listener uses to analyze and understand the environment. Computer analyses that attempt to mimic human analysis of a scene must first perform Audio Scene Segmentation (ASS). ASS find applications in surveillance, automatic speech recognition and human computer interfaces. Microphone arrays can be employed for extracting streams corresponding to spatially separated sources. However, when a source moves to a new location during a period of silence, such a system loses track of the source. This results in …
