Kramers-Kronig Anomalous Dispersion On Single-Mode Fiber-Optic Couplers And Tapers, Arnel C. Lavarias

Electrical & Computer Engineering Theses & Dissertations

The Kramers-Kronig relations couple the real and imaginary part of the dielectric constant of a medium, namely the refractive index n(ω) and the extinction coefficient κ(ω). Changes in n(ω) due to normal and anomalous dispersion (Kramers-Kronig effect) are investigated for the first time using fiber optic couplers and tapers. Kramers-Kronig effect is induced by evanescent wave absorption in these devices. Couplers and tapers have oscillatory spectral outputs that are highly sensitive to the refractive index of the surrounding medium. Theoretical modeling of the Kramers-Kronig effect on couplers and tapers shows two distinct effects. First, the spectral outputs of these devices …

Numerical Simulations Of Full- Scale Corroded Pipe Tests With Combined Loading, Samit Roy, S. Grigory, M. Smith, M. F. Kanninen, M. Anderson

Mechanical and Aerospace Engineering Faculty Research & Creative Works

The ANSI/ASME B31G guideline has been useful to pipeline operators in assessing the integrity of corroded line pipe. Because large safety margins have had to be incorporated, the guidelines can be excessively conservative, which in turn can force costly repairs and replacements that may not actually be necessary. On the other hand, because the current guidelines consider only pressure loading and neglect bending and axial compression, they could give nonconservative failure predictions when combined loading exists. Therefore, a study was initiated to develop a theoretically sound methodology for assessing the integrity of corroded line pipe subjected to combined loading. A …

Chemical Stability Study Of Bace0.9Nd0.1O3−Α High Temperature Proton-Conducting Ceramic, Fanglin Chen, O. Toft Sorensen, Guangyao Meng, Dingkum Peng

Faculty Publications

BaCe_0.9Nd_0.1O_3−a (BCN) ceramic is known to be an excellent high-temperature proton conductor and is a candidate electrolyte for use in solid oxide fuel cells, hydrogen or steam sensors and steam electrolysers. In this work, the chemical stability of BCN was investigated systematically by combining XRD and DTA–TG techniques to study its processing compatibility and its feasibility in potential applications. It was found that above 1200 °C, BCN reacted with alumina or zirconia, leading to the loss of barium and an excess of cerium. In cold water, both sintered BCN disks and powder samples had very …

Distribution Of Free Marine Viruses Of Lower Chesapeake Bay And Their Effects On Life-History Parameters Of The Estuarine Copepod Acartia Tonsa Dana, Lisa A. Drake

OES Theses and Dissertations

Naturally occurring viruses are very abundant in fresh, estuarine, and marine waters, with densities on the order of 10⁵-10⁸ viruses ml^-1. Research has focused on virus effects on bacteria, cyanobacteria, and phytoplankton, as well as mechanisms of virus production and decay. However, little is known about the distribution of viruses in benthic environments or virus effects on organisms in higher trophic levels.

To determine the distribution of virus-like particles (VLPs) and bacteria in the lower Chesapeake Bay, vertical profiles of VLPs and bacteria were determined through the water column and 15-25 cm into the sediment …

Modeling Plankton Community Structure Under Environmental Forcing On The Southeastern United States Continental Shelf, Andrew Glenn Edward Haskell

OES Theses and Dissertations

A system of coupled ordinary differential equations was developed to investigate the time-dependent behavior of phytoplankton, copepod, and doliolid populations associated with upwelling features on the outer southeastern U.S. continental shelf. Model equations describe the interactions of nitrate, ammonium, two phytoplankton size fractions, five copepod developmental stages, doliolids, and a detrital pool. Model dynamics are based primarily upon data obtained from field and laboratory experiments made for southeastern U.S. continental shelf plankton populations. Numerous simulations were performed to investigate the effects of environmental variability on the temporal distribution of the structure of resident plankton populations. Variations on a reference simulation, …

Liability Of Suppliers Of Natural Raw Materials And The Restatement (Third) Of Torts: Products Liability--A First Step Toward Sound Public Policy, M. Stuart Madden

Elisabeth Haub School of Law Faculty Publications

From its inception, the law governing liability for damage or injuries caused by defective products has pertained to potential liability for products that have been processed, finished, or fabricated. Naturally occurring raw materials, for the most part, have been considered beyond doctrinal concern, largely because characterizing a merchantable raw material, such as copper or pigiron, as defective is conceptually difficult. Nevertheless, certain doctrines that developed for the application of products liability to other products have gained sporadic application to naturally occurring raw materials, including the sophisticated purchaser defense, the bulk supplier defense, and the ingredient supplier defense. Madden argues that …

The Utility Of International Law For Protecting Women's Health Rights, Vanessa Merton

Elisabeth Haub School of Law Faculty Publications

There is one area, however, where international law seems to hold promise; certain cultural practices that pose special, direct threats to the lives and health of women (although male infants and children often share women's vulnerability in this regard). I have in mind sexual slavery, coercive prostitution and pornographic exploitation, rape, compulsory marriage, coerced impregnation and its converse, coerced abortion and sterilization; spousal abuse, dowry deaths and coerced suicide, female infanticide and sex-specific abortion. All of these practices are the product not of microbes, poor hygiene, or a lack of health care, but of deliberate human behavior. All these practices …

Effects Of Membrane Rotation And Transmembrane Pressure On The High-Shear Rotary Ultrafiltration Of An Oily Wastewater., Roger C. Viadero

Graduate Theses, Dissertations, and Problem Reports (ETD)

Large volumes of spent oil-in-water emulsions are produced in the metal-working industry. The treatment of oily wastewaters with conventional membrane separation technologies is limited by the low permeate flux observed at high oil concentrations due to difficulty pumping concentrated solutions at high recirculation velocities. In the high-shear rotary ultrafiltration (UF) unit, disk membranes are rotated at speeds up to 1,750 rpm to generate hydraulic turbulence which scours the membrane surface. Thus, the pump is required only to provide transmembrane pressure and a small amount of recirculation. The objective of this research was to perform a parametric waste-specific study on the …

Burnout And Depression Among Roman Catholic Secular, Religious, And Monastic Clergy., Stephen Gerard Virginia

Graduate Theses, Dissertations, and Problem Reports (ETD)

Burnout and depression among Roman Catholic secular, religious order, and monastic (Cistercian) priests was investigated using the Maslach Burnout Inventory (MBI) and the Center for Epidemiological Studies-Depression (CES-D) scale. Additionally, a Self-Report-Inventory was included (SRI) requesting information on demographics as well as four categories of predictor variables (vocational satisfaction, social support, spiritual activities, and physical environment) associated with burnout and depression. All participants were randomly selected from the National Catholic Director. The survey yielded a return rate of 90.67% with 63.11% completing the survey. Secular clergy reported significantly greater emotional exhaustion than did monastic clergy. Secular priests also had significantly …

There Was Something In The Water: Parallels In Paradigms In English And Physics, 1880 To 1940., Tracy Joan Demars

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study posits that a paradigm is a shared vision of reality that governs how practitioners define and relate to the many and varied components that make up that reality. Using this definition, the author presents a visual model using concentric spheres of increasing abstraction that rearrange T. S. Kuhn's four components of a disciplinary matrix that he articulated in the 1969 Postscript to The Structure of Scientific Revolutions. Based on this model and D'Amico's criteria for a coherent narrative, the study assesses the two primary paradigms, labeled the Object-Oriented paradigm and the Subject-Oriented paradigm, that existed in the fields …

Effect Of Hydrous Oxide Coatings On Adsorption Of Oxyanions By Clay Minerals., Swarn S. Dhaliwal

Graduate Theses, Dissertations, and Problem Reports (ETD)

Five clay minerals (Well Crystallized Kaolinite (KWC), Poorly Crystallized Kaolinite (KPC), Illite, Attapulgite, and Montmorillonite) with a range of surface characteristics were selected to investigate the adsorption of three oxyanions (molybdate, selenite, and selenate). The minerals were coated with five different levels of each of Fe and Al hydrous oxides. The charge characteristics were determined using potentiometric titration. Adsorption was studied by batch experiment at 11 different concentrations of each of the oxyanions at three different pH levels.

Internet Red Light Districts? Domain Name Proposal For Regulatory Zoning Of Obscene Content, April Mara Barton

Law Faculty Publications

The Internet has a relatively short, yet rich history of free speech and independence from governance. While this independence is an important part of the Internet's past, it has become increasingly clear that the Internet must somehow be regulated in order to ensure stability to the Internet community and viability as a communications medium. Without regulation the Internet will eventually nullify its own legitimacy as an effective and reputable mode of communication. It is this negative effect which serves as the impetus for Internet governance that is proposed in this article.

History Of The Court Reporter In The Appellate Courts Of Pennsylvania, Joel Fishman

Law Faculty Publications

States have traditionally published the decisions of their intermediate and highest courts.¹ Legal historians, in recent years, have written extensively on the history of court reporting and court reports.² These historical accounts have revealed that many famous judges and lawyers throughout the country gained prominent reputations stemming from the publishing of their decisions.³ In the "nineteenth century, the development of court reports received attention from the legal community through reviews in many of the leading periodicals of the day."⁴ By 1900, however, the periodical literature contained only a small number of reviews of individual state reports. …

Oligopsony Elements In The Recycled Wastepaper Market: Existence And Implications., Aref Aghaei-Hervani

Graduate Theses, Dissertations, and Problem Reports (ETD)

Old newspaper (ONP) is the largest single component (14%) of total U.S. Municipal Solid Waste (MSW). The rising problems associated with disposal of MSW in landfills can be dealt with if the volume of the waste stream is reduced by recycling. The wastepaper recycling market, in particular ONP, has not been successful in utilizing the ONP generated. The existence of high sunk costs for entry into deinking market, along with the small numbers of buyers in the ONP market were identified as reasons that the ONP market had oligopsony elements. This research examined oligopsony in the ONP market and its …

Matching Appalachians' Preventive Services' Utilization And Managed Care Strategies For Preventive Care., Mayur Mohan Amonkar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite increasing emphasis on disease prevention and health promotion and evidence demonstrating the effectiveness of such services, high morbidity and mortality rates in Appalachia suggest a problem with appropriate utilization of preventive services in this region. Also, growth in managed care programs signify a greater role for managed care organizations (MCOs) in preventive care. The overall goal of this study was to assess the preventive care behavior of Appalachians, evaluate strategies used by MCOs to ensure appropriate utilization of preventive services, and identify barriers/facilitators to the provision/utilization of such services. In phase I of this study, secondary data analysis of …
