Extended Tailing Of Bacteria Following Breakthrough At The Narrow Channel Focus Area, Oyster, Virginia, Pengfei Zhang, William P. Johnson, Timothy D. Scheibe, Keun-Hyung Choi, Fred C. Dobbs, Brian J. Mailloux

OES Faculty Publications

Extended tailing of low bacterial concentrations following breakthrough at the Narrow Channel focus area was observed for 4 months. Bacterial attachment and detachment kinetics associated with breakthrough and extended tailing were determined by fitting a one-dimensional transport model to the field breakthrough-tailing data. Spatial variations in attachment rate coefficient (k(f)) were observed under forced gradient conditions (i.e., k(f) decreased as travel, distance increased), possibly because of decreased bacterial adhesion with increased transport distance. When pore water velocity decreased by an order of magnitude at 9 days following injection, apparent bacterial attachment rate coefficients did not decrease with velocity as expected …

Hierarchical Text Classification And Evaluation, Aixin Sun, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Hierarchical Classification refers to assigning of one or more suitable categories from a hierarchical category space to a document. While previous work in hierarchical classification focused on virtual category trees where documents are assigned only to the leaf categories, we propose atop-down level-based classification method that can classify documents to both leaf and internal categories. As the standard performance measures assume independence between categories, they have not considered the documents incorrectly classified into categories that are similar or not far from the correct ones in the category tree. We therefore propose the Category-Similarity Measures and Distance-Based Measures to consider the …

An Interactive Journey: Creative Development For Young Children, Nattawan Wanglee

Theses

Creativity begins in infancy and can be developed when children grow up. Young children are at their peak of creative functioning, which declines with age. They are unique individuals and are highly imaginative. Creativity and imagination are strongly related. Even though all children are capable of creativity, the potential to create remains dormant without practice. Creativity requires practice to flourish. Therefore, creativity plays an important role as much as knowledge does. To educate children, creativity also needs to be paid attention too. Children should be encouraged to represent their world creatively by allowing them to choose what they want to …

Practical Issues For The Application Of High-Performance Concrete To Highway Structures, John J. Myers, Yumin Yang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In recent years, the advantages of high-performance concrete (HPC) have been well documented. Among others, these advantages include enhanced design flexibility and improved durability performance that results in reduced maintenance costs and an increased service life. Despite these obvious benefits, the implementation of HPC has been very slow. This can be attributed to several factors including the uncertainty related to current design codes and a lack of familiarity of designers and contractors with practices and requirements for proper design and construction of high-performance concrete structures. This paper introduces and discusses several fundamental issues that affect the implementation of HPC and …

Dc Power-Bus Modeling And Design With A Mixed-Potential Integral-Equation Formulation And Circuit Extraction, Jun Fan, James L. Drewniak, Hao Shi, James L. Knighten

Electrical and Computer Engineering Faculty Research & Creative Works

Application of a circuit extraction approach based on a mixed-potential integral equation formulation (CEMPIE) for dc power-bus modeling in high-speed digital designs is detailed herein. Agreement with measurements demonstrates the effectiveness of the approach. Dielectric losses are included into the calculation of Green's functions, and thus, incorporated into the rigorous first principles formulation. A SPICE model is then extracted from the discretized integral equation. A quasistatic approximation is used for Green's functions to keep the extracted circuit elements frequency independent. Previous work has established a necessary meshing criterion in order to ensure accuracy for a given substrate thickness and dielectric …

Emi Mitigation With Multilayer Power-Bus Stacks And Via Stitching Of Reference Planes, Xiaoning Ye, David M. Hockanson, Min Li, Yong Ren, Wei Cui, James L. Drewniak, Richard E. Dubroff

Electrical and Computer Engineering Faculty Research & Creative Works

General methods for reducing printed circuit board (PCB) emissions over a broad band of high frequencies are necessary to meet EMI requirements, as processors become faster and more powerful. One mechanism by which EMI can be coupled off a PCB or multichip module (MCM) structure is from high-frequency fringing electric fields on the dc power and reference planes at the substrate periphery An approach for EMI mitigation by stitching multiple ground planes together along the periphery of multilayer PCB power-bus stacks with closely spaced vias is reported and quantified in this paper. Power-bus noise induced EMI and coupling from the …

Pickup And Delivery Problem With Time Windows: Algorithms And Test Case Generation, Hoong Chuin Lau, Zhe Liang

Research Collection School Of Computing and Information Systems

In the pickup and delivery problem with time windows (PDPTW), vehicles have to transport loads from origins to destinations respecting capacity and time constraints. In this paper, we present a two-phase method to solve the PDPTW. In the first phase, we apply a novel construction heuristics to generate an initial solution. In the second phase, a tabu search method is proposed to improve the solution. Another contribution of this paper is a strategy to generate good problem instances and benchmarking solutions for PDPTW, based on Solomon's benchmark test cases for VRPTW. Experimental results show that our approach yields very good …

Stacked Subwavelength Gratings As Circular Polarization Filters, Gregory P. Nordin, P. C. Deguzman

Faculty Publications

We have stacked subwavelength gratings (SWGs) on a single substrate to create a compact, integrated circular polarization filter. The SWGs consist of a wire grid polarizer and a broadband form-birefringent quarter-wave plate (QWP). Rigorous coupled-wave analysis was used to design the QWP for operation over the 3.5-5.0 m wavelength range. The fabricated silicon broadband QWP exhibited a phase retardance of 82-97° across this wavelength range. Two stacked structures are presented, each with a different wire grid polarizer fabricated on an organic planarization layer (SU-8) that is deposited on a QWP grating. Transmittance measurements of the first structure when illuminated with …

Capillary Flow In Interior Corners: The Infinite Column, Mark M. Weislogel

Mechanical and Materials Engineering Faculty Publications and Presentations

Capillary flow of a sinusoidally perturbed liquid column in an interior corner of infinite extent is solved using lubrication theory. Due primarily to the length scales selected to nondimensionalize the momentum equation, an analytic time scale governing the settling of the perturbation is determined. The time scale, which is shown to be independent of a steady base state flow, proves useful in rapidly predicting transients for surface settling in certain liquid-bearing tanks of spacecraft employing interior corners for fluids management purposes. The asymptotic analysis is extended to address flows along interior corners whose faces are slightly nonplanar. The generalized formulation …

An Arrow To The Heart: The Love And Death Of Postmodern Legal Scholarship, Stephen M. Feldman

Vanderbilt Law Review

Modernist legal writers, including Dennis Arrow in his well-known Pomobabble article, commonly criticize postmodern legal scholars for being muddle-headed nihilistic thinkers who write indecipherable jargon-filled nonsense and lack political convictions. Professor Feldman responds to these and other related criticisms and, in doing so, explains some key components of postmodernism. For instance, he describes how the pervasiveness of postmodern culture infuses legal scholarship with certain postmodern themes. Ironically, then, even the most vehement critics, like Arrow, display a surprising if unwitting affinity for postmodernism. Finally, in order to deflect precipitate denunciations of postmodernism, Professor Feldman suggests a refinement of terms, dividing …

Are Shaming Punishments Beautifully Retributive? Retributivism And The Implications For The Alternative Sanctions Debate, Dan Markel

Vanderbilt Law Review

In the last few years, scholars and policymakers in the area of criminal justice have focused an increasing amount of attention on two topics. The first is the retributivist theory of punishment ("retributivism");' the second is the development of alternative sanctions to the orthodoxy of incarcerating criminals in publicly managed prisons. This Article is about what connections may properly be drawn between what justifies punishment and how we actually go about punishing offenders.

A preliminary word on retributivism may be helpful. Retributivism is a theory about retribution, and retribution's features, or its definition, may be understood in either a weak …

The New Face Of Creationism: The Establishment Clause And The Latest Efforts To Suppress Evolution In Public Schools, Deborah A. Reule

Vanderbilt Law Review

Over seventy-five years after the impassioned debate be- tween William Jennings Bryan and Clarence Darrow echoed through a hot Tennessee courtroom, the controversial confrontation over science, religion, law, and education can still be heard in legislative halls, courtrooms, schools, and homes across the nation. The now infamous "Scopes Monkey Trial" of 19253 brought the debate between religious fundamentalism and modern day scientific theory to the forefront and sparked twenty state legislatures to consider measures to prohibit the teaching of evolution in public schools. Nearly a century later, the dispute rages on. Twenty states considered anti-evolution measures in both the 1920s …

Unreasonable Probability Of Error, Jed Handelsman Shugerman

Faculty Scholarship

In Strickland v. Washington, the Supreme Court sought to create a uniform standard to guarantee effective assistance of counsel to criminal defendants, to "ensure a fair trial," and to assure the reliability of "a just result."' Justice O'Connor's majority opinion created a two-pronged test for overturning a trial verdict: deficient performance and resulting prejudice. The Court explicitly established a difficult burden for proving deficient performance,² but set a moderate standard for prejudice as the "reasonable probability that, but for counsel's unprofessional errors, the result of the proceeding would have been different. A reasonable probability is a probability sufficient …

The Competency Conundrum: Problems Courts Have Faced In Applying Different Standards For Competency To Be Executed, John L. Farringer, Iv

Vanderbilt Law Review

Throughout Anglo-American legal history, there has been a general agreement, based on numerous rationales, that mentally incompetent inmates should not be executed for their crimes. The recurring problem, however, is how to define "incompetence" or "insanity." Legislatures and courts have sought to provide a common- sense definition, but in practice judges must confront highly technical terminology from the ever evolving field of psychiatry. Additionally, the definition must be flexible enough to apply to a variety of cases, while being universal enough to assure that all defendants are treated fairly and equally.

At hearings to determine a prisoner's competency to be …

High Frequency Of Extra-Pair Paternity In Eastern Kingbirds, Diane L. Rowe, Michael T. Murphy, Robert C. Fleischer, Paul G. Wolf

Biology Faculty Publications and Presentations

Genetic parentage in the socially monogamous and territorial Eastern Kingbird( Tyrannust tyrannus) was examined in a central New York population by multilocus DNA fingerprinting. Extra-pair young were identified in 60% (12 of 20) of nests. Of the 64 nestlings profiled, 42% were sired by extra-pair males, but no cases of conspecific brood parasitism were detected. These results are markedly different from a previous electrophoretic study of the same species in a Michigan population, which reported 39% of nestlings were unrelated to one (typically the mother, quasiparasitismo)r both (conspecificb roodp arasitism) of the putative parents. In the New York population, extra-pairp …

Three-Body Coulomb Problem Probed By Mapping The Bethe Surface In Ionizing Ion-Atom Collisions, Robert Moshammer, Appathurai N. Perumal, Michael Schulz, V. D. Rodriguez, Holger Kollmus, Rido Mann, Siegbert Hagmann, Joachim Hermann Ullrich

Physics Faculty Research & Creative Works

The three-body Coulomb problem has been explored in kinematically complete experiments on single ionization of helium by 100 MeV / u C 6 + and 3.6 MeV / u u 5 3 + impact. Low-energy electron emission (E e < 150 eV ) as a function of the projectile deflection ϑ p (momentum transfer), i.e., the Bethe surface [[15]], has been mapped with Δ ϑ p ± 25 nanoradian resolution at extremely large perturbations (3.6 MeV / uAu⁵³⁺ ) where single ionization occurs at impact parameters of typically 10 times the He K -shell radius. The experimental data are not in agreement with state-of-the-art continuum distorted wave-eikonal initial state theory.

A Political History Of The Establishment Clause, John C. Jeffries Jr., James E. Ryan

Michigan Law Review

Now pending before the Supreme Court is the most important church-state issue of our time: whether publicly funded vouchers may be used at private, religious schools without violating the Establishment Clause. The last time the Court considered school aid, it overruled precedent and upheld a government program providing computers and other instructional materials to parochial schools. In a plurality opinion defending that result, Justice Thomas dismissed as irrelevant the fact that some aid recipients were "pervasively sectarian." That label, said Thomas, had a "shameful pedigree." He traced it to the Blaine Amendment, proposed in 1875, which would have altered the …

The Limits Of Localism, Richard C. Schragger

Michigan Law Review

In Chicago v. Morales, the Supreme Court struck down Chicago's Gang Congregation Ordinance, which barred "criminal street gang members from loitering with one another or with other persons in any public place." The stated purpose of the ordinance was to wrest control of public areas from gang members who, simply by their presence, intimidated the public and established control over identifiable areas of the city, namely certain inner-city streets, sidewalks, and corners. The ordinance required that police officers determine whether at least one of two or more persons present in a public place were members of a criminal street gang …

Bridge Lifetime System Reliability Under Multiple Limit States, Allen C. Estes, Dan M. Frangopol

Architectural Engineering

A system reliability approach to minimizing the life-cycle cost of a deteriorating structure offers significant advantages such as a rational assessment of the assumed risk of failure, and an understanding of the importance and contribution of individual components to the overall reliability of the structure. The reliability of a structural system as a whole is the measure of its overall performance. This measure has to include both ultimate and serviceability limit states. A system model of a structure traditionally consists of a series-parallel combination of strength-based component limit states. Serviceability limit states however, can play a tremendously important role in …
