Nscat High-Resolution Surface Wind Measurements In Typhoon Violet, W. Linwood Jones, Vincent J. Cardone, Willard J. Pierson, Josko Zec, Larry P. Rice, Andrew Cox, Winfield B. Sylvester

Faculty Bibliography 1990s

NASA scatterometer (NSCAT) measurements of the western Pacific Supertyphoon Violet are presented for revolutions 478 and 485 that occurred in September 1996. A tropical cyclone planetary boundary layer numerical, model, which uses conventional meteorological and geostationary cloud data, is used to estimate the winds at 10-m elevation in the cyclone. These model winds are then compared with the winds inferred from the NSCAT backscatter data by means of a novel approach that allows a wind speed to be recovered from each individual backscatter cell. This spatial adaptive (wind vector) retrieval algorithm employs several unique steps. The backscatter values are first …

Numerical Modeling Of Thermal Refraction In Liquids In The Transient Regime, Dmitriy I. Kovsh, David J. Hagan, Eric W. Van Stryland

Faculty Bibliography 1990s

We present the results of modeling of nanosecond pulse propagation in optically absorbing liquid media. Acoustic and electromagnetic wave equations must be solved simultaneously to model refractive index changes due to thermal expansion and/or electrostriction, which are highly transient phenomena on a nanosecond time scale. Although we consider situations with cylindrical symmetry and where the paraxial approximation is valid, this is still a computation-intensive problem, as beam propagation through optically thick media must be modeled. We compare the full solution of the acoustic wave equation with the approximation of instantaneous expansion (steady-state solution) and hence determine the regimes of validity …

Partial Photoionization Cross Section And Resonance Structure Of Br, Dong Lin, H. P. Saha

Faculty Bibliography 1990s

The partial photoionization cross sections for the outer p subshell of the ground state of bromine are calculated in all available open channels as determined by LS coupling for photon energies from the P-3 to S-1 thresholds. The electron correlations which an important in this case have been taken into account using the multiconfiguration Hartree-Fock approximation for the hound and the continuum wave functions. The resonance structures between the P-3 and D-1 threshold and between the D-1 and S-1 threshold have been identified. In order to compare with experiment a frame transformation is applied to transform the LS dipole matrix …

Processing And Characterization Of Nanometer Sized Copper Sulfide Particles, S. Seal, L. Bracho, S. Shukla, J. Morgiel

Faculty Bibliography 1990s

Nanomaterials have attracted considerable, attention in modern-day technology. In this article, sulfide nanoparticles of industrial interest are formed by the sol-gel process using metal chloride precursors dissolved in a mixture of silica gel and organic cellulose network followed by a chemical reaction with hydrogen sulfide gas. Particles are then heated in a vacuum oven. While scanning and transmission electron microscopy are used to study their morphology and structure in the nanometer scale, x-ray photoelectron spectroscopy is employed to understand the bonding chemistry and the stoichiometry of the sulfide particles as a function of H2S exposure and heat treatment. The results …

Invariant Painleve Analysis And Coherent Structures Of Two Families Of Reaction-Diffusion Equations, Ugur Tanriver, S. Roy Choudhury

Faculty Bibliography 1990s

Exact closed-form coherent structures (pulses/fronts/domain walls) having the form of complicated traveling waves are constructed for two families of reaction-diffusion equations by the use of invariant Painleveacute analysis. These analytical solutions, which are derived directly from the underlying PDE's, are investigated in the light of restrictions imposed by the ODE that any traveling wave reduction of the corresponding PDE must satisfy. In particular, it is shown that the coherent structures (a) asymptotically satisfy the ODE governing traveling wave reductions, and (b) are accessible to the PDE from compact support initial conditions. The solutions are compared with each other, and with …

Histogram Specification Of 24-Bit Color Images In The Color Difference (C-Y) Color Space, A. R. Weeks, L. J. Sartor, H. R. Myler

Faculty Bibliography 1990s

Histogram equalization and specification have been widely used to enhance information in a gray scale image, with histogram specification having the advantage of allowing the output histogram to be specified as compared to histogram equalization, which attempts to produce an output histogram that is uniform Unfortunately, expanding histogram techniques to color images is not very straightforward Since humans are sensitive to chromatic changes, care must be taken to ensure that incorrect colors are not produced. Additionally expanding the one-dimensional histogram used in gray level histogram techniques to a joint histogram (usually of three variables representing the primary colors of red, …

Nscat Normalized Radar Backscattering Coefficient Biases Using Homogenous Land Targets, Josko Zec, David G. Long, W. Linwood Jones

Faculty Bibliography 1990s

The NASA scatterometer (NSCAT) is a spaceborne radar sensor designed to measure the normalized radar backscattering coefficient sigma(o) of the Earth's surface. Over the ocean, backscatter measurements are used to infer surface wind vectors. Wind retrieval is based on a statistical relationship between short-ocean wave roughness (that causes the backscatter) and the surface wind speed and direction. For NSCAT geometry, multiple antennas are used to provide backscatter measurements at several azimuth directions to resolve wind direction ambiguities. To achieve the desired wind vector accuracy, these antenna beams must be calibrated within a few tenths of a decibel. A simple relative-calibration …

Finding A Voice: Poetry And Performance With First Graders, Lisa Lenz Bianchi

Doctoral Dissertations

This is a qualitative research study of a ten week immersion unit in the reading, writing, and performance of poetry conducted in a first grade classroom in Closter, New Jersey during the winter of 1995. The three girls selected as case studies show the ways in which remarkably different children expand their repertoires of ways with words as speakers, readers, and writers. Danielle, a performative speaker, learns to make her tacit knowledge about performance part of her explicit frames of reference. This shift enables her to serve as a coach for peers who are less adept at crafting performative texts. …

Queering/Querying Identities: The Roles Of Integrity And Belonging In Becoming Ourselves, Cari Ann Elizabeth Moorhead

Doctoral Dissertations

This dissertation presents a picture of the complexities and contradictions in the daily lives of people in the Seacoast area of New Hampshire who identify as, or are identified as, lesbian, gay, bisexual, transgender, queer, questioning and allied people (LGBTQQA). The focus of this study is the "Create Our Destiny" conference, a social change project. Philosophically, I viewed this project through a Postmodern feminist lens, and methodologically I used a grounded theory approach.

This dissertation is divided into three sections. Within section one, I present more detailed descriptions of my philosophical and methodological approaches, a description of the geographical and …

The Effects Of Medicaid And Maternal Depression On Prenatal Care And Infant Health, Lisa C. Defelice

Doctoral Dissertations

While in recent years, the infant health production function literature has expanded to incorporate behavioral inputs into the production of infant health current research fails to incorporate the Medicaid-private insurance choice into the mother's decision making process. This dissertation seeks to address this by treating private insurance and Medicaid as endogenous while considering the effects that the Medicaid eligibility rules have on both kinds of coverage. Medicaid and private insurance are entered directly into the health production function so that quality effects may be captured. In addition, a woman's state of mental health is also incorporated into the health production …

Topics In Chaotic Secure Communication, Andrew Thomas Parker

Doctoral Dissertations

Results in nonlinear dynamics and chaos during this decade have been applied to problems in secure communications with limited success. Most of these applications have been based on the chaotic synchronization property discovered by Pecora and Carroll in 1989 [37]. Short [44, 45, 48] demonstrated the effectiveness of nonlinear dynamic (NLD) forecasting methods in breaking this class of communication schemes. In response, investigators have proposed enhancements to the basic synchronization technique in an attempt to improve the security properties. In this work two of these newer communication systems will be analyzed using NLD forecasting and other techniques to determine the …

The Effects Of Reversible Inactivation By Lidocaine Of Ventral Striatum And Intralaminar Nucleus Of The Thalamus In Match To Sample Tasks With And Without Delays Trained In The Lever Box, Mary Christine Porter

Doctoral Dissertations

Three experiments systematically examined the effects of reversibly inactivating intralaminar nuclei and ventral striatum with infusions of lidocaine. The ventral striatum and the intralaminar nucleus were targeted based on deficits in accuracy and speed of responding in delayed conditional discrimination tasks associated with permanent lesions of these structures (Mair, Burk and Porter, 1998).

The present research showed that a 4.0 mul of 2% lidocaine caused impairments accuracy, but not in response speed, in a match to sample task trained in the lever box without delays when the internal cannula projects 0.5 mm from the guide cannula. One microliter of 2%, …

Domestic Visions And Shifting Identities: The Urban Novel And The Rise Of A Consumer Culture In America, 1852-1925, Nancy Helen Von Rosk

Doctoral Dissertations

Domestic Visions reexamines the tradition of the urban novel in America by reading the works of Nathaniel Hawthorne, Henry James, William Dean Howells, Theodore Dreiser, Paul Laurence Dunbar, Edith Wharton, Abraham Cahan and Anzia Yezierska within the historical and cultural contexts of an evolving urban consumer culture. Bringing together not only a wide range of canonical and non-canonical texts, but also an analysis of America's shifting domestic ideals over the last half of the nineteenth and early twentieth centuries, this study traces the impact of a new spectacular urban public culture on both the private realm and those who are …

Atmospheric Transport And Deposition Of Water -Soluble Nitrogen To The Gulf Of Maine, Carolyn Estelle Jordan

Doctoral Dissertations

An intensive sampling program was carried out from May 1994 through November 1997 on the shore of the Gulf of Maine in New Castle, New Hampshire. Daily (24 hour averages) samples of bulk aerosol and gas phase HNO3, precipitation, and 20 aerosol size distributions were obtained. Particulate NH4+ and gas phase HNO3 were the dominant water-soluble nitrogen species in the atmosphere. Nitrate was the dominant inorganic nitrogen ion in precipitation.

These samples were used with 1000 hPa streamlines to classify sampled air masses according to their surface level transport and chemistry. Overall, mixed conditions occurred in 42% of the samples, …

Language's "Bliss Of Unfolding" In And Through History, Autobiography And Myth: The Poetry Of Rita Dove, Carol Keyes

Doctoral Dissertations

This dissertation focuses on the first five books of poetry published by the American poet Rita Dove: The Yellow House on the Corner (1980), Museum (1983), Thomas and Beulah (1986; awarded the Pulitzer Prize in 1987), Grace Notes (1989), and Mother Love (1995). It situates her work within the whole field of American poetic discourse. Dove's relationship to myriad strands of American ars poetica traditions arises out of patterns of amplification and negotiation worked out in Dove's poetry in relation to a wide range of such traditions. Thus, the study's methodology proceeds from the poet T. S. Eliot's dictum that …

Learning To Read Music Cooperatively In A Choral Setting: A Case Study, Andrew Inzenga

Doctoral Dissertations

Two volunteer cooperative teams of ninth grade girls were studied for six months to discover whether and how they learned to read music. The two teams represented novice students and students who had received private instruction. Study teams represented the population of the freshman Girls Chorus. Teams met regularly during daily chorus rehearsals, with only occasional help from the director. These meetings were analyzed through video tape recordings to observe if students employed traditional teaching and learning strategies to assist each other in learning. It was determined that team members regularly use certain teaching and learning strategies to assist in …

Using Character Varieties: Presentations, Invariants, Divisibility And Determinants, Jeffrey Allan Hall

Doctoral Dissertations

If G is a finitely generated group, then the set of all characters from G into a linear algebraic group is a useful (but not complete) invariant of G . In this thesis, we present some new methods for computing with the variety of SL2C -characters of a finitely presented group. We review the theory of Fricke characters, and introduce a notion of presentation simplicity which uses these results. With this definition, we give a set of GAP routines which facilitate the simplification of group presentations. We provide an explicit canonical basis for an invariant ring associated with a symmetrically …
