Model-Based Estimation Of Wind Fields Over The Ocean From Wind Scatterometer Measurements. I. Development Of The Wind Field Model, David G. Long, Jerry M. Mendel

Faculty Publications

For pt.II see ibid., vol.28, no.3, p.361-373 (1990). A parametric model for near-surface mesoscale wind fields suitable for use in a model-based approach to estimate the wind field over a large region of the scatterometer measurement swath from measurements of the radar backscatter of the ocean's surface is discussed. The assumptions made in developing the model are described, and the accuracy of the resulting model is evaluated. The model is based only on scatterometer data and is computationally tractable, consisting of a linear equation relating the near-surface wind field to a vector of model parameters which is estimated from the …

The Brass Plates Version Of Genesis, Noel B. Reynolds

Faculty Publications

Phraseology occurring in Joseph Smith's "Book of Moses" matches Book of Mormon passages, but not the Bible. Given that the Book of Mormon claims a different source, the brass plates, this finding would be consistent with the conclusion that the Book of Moses and the brass plates versions of Genesis are more similar to each other than to the modern biblical version.

Photoluminescence Studies In Znxcd1-Xte Single Crystals, David D. Allred, Jesus González-Hernández, Elías López-Cruz, Worth P. Allred

Faculty Publications

The crystalline quality of ZnxCd1-xTe single crystals prepared by a modified Bridgman method with 0≤x≤0.05 has been analyzed using photoluminescence. The spectrum of a typical sample is dominated by lines originating from the recombination of free and bound excitons. Lines due to free excitons in their ground and first excited states are observed in both the pure CdTe and the mixed crystals. Excitons bound to Dc vacancies are observed in the pure CdTe crystal but not in the mixed crystal. Weaker and broader features appearing at energies below the exciton emission range were associated with transitions involving free-to-bound and bound-to-bound …

Opportunity, Willingness, And The Diffusion Of War, Randolph M. Siverson, Harvey Starr

Faculty Publications

Using borders and alliances as indicators of opportunity and willingness, respectively, we test the relationship between the sea and the diffusion of war during the 1816-1965 period. The impact of borders and alliances, individually and in combination, on the growth of ongoing war through "infectious" diffusion is shown through the comparison of baseline cases to cases where states at peace were exposed to various "treatments" comprised of warring border nations or warring alliance partners. The findings indicate that the probability of war diffusion is substantially increased as opportunities and willingness increase, particularly when such geographic and political factors are combined. …

Dante And The Franciscan Movement, Ilona Klein

Faculty Publications

Consider what might happen if, instead of nuclear bombs and pollution, twentieth-century technology had provided us with time machines; affordable, handy appliances to be bought readily and kept in living rooms, perhaps next to the sofa. In order to travel through time, one would only need to sit back comfortably and turn the electronic control panel's time knob in the proper direction; then, push a button when the indicator reaches the year one wants to visit. . .

Deposition Of Zinc Selenide By Atomic Layer Epitaxy For Multilayer X-Ray Optics, J.K. Shurtleff, David D. Allred, R. T. Perkins, J. M. Thorne

Faculty Publications

Thin film deposition techniques currently being used to produce multilayer x-ray optics (MXOs) have difficulty producing smooth, uniform multilayers with d-spacings less than about twelve angstroms. We are investigating atomic layer epitaxy (ALE) as an alternative to these techniques. ALE is a chemical vapor deposition technique which deposits an atomic layer of material during each cycle of the deposition process. The thickness of a film deposited by ALE depends only on the number of cycles. Multilayers deposited by ALE should be smooth and uniform with precise d-spacings which makes ALE an excellent technique for producing multilayer x-ray optics. We have …

The Burden Of Responsibility In The Libro De Buen Amor, Lynn Williams

Faculty Publications

In three of the early sections of the Libro de buen amor, Juan Ruiz explains to his public how, for various reasons, he is conditioned to love women. In stanzas 71-76 he uses the unimpeachable authority of Aristotle to argue that men and animals are biologically determined to seek 'juntamiento con fenbra plazentera' (st. 71d), and since he is a man like any other, it is natural, perhaps even inevitable, that from time to time he too should feel the attraction of the opposite sex. Paraphrasing St Paul (I Thessalonians 5.21), the Archpriest tells us rather cheekily that one must …

The Costs Of Settlement: The Impact Of Scarcity Of Adjudication On Litigating Lawyers, Kevin C. Mcmunigal

Faculty Publications

This Article, by comparison, focuses on the implications of lack of trial experience for litigating lawyers. Does lack of trial experience affect the way lawyers function in litigation? Does it influence their performance as advocates? As negotiators settling cases? Does it affect adherence to existing ethical standards such as those regarding competence and conflict of interest? Can one expect lawyers to understand, respect, and adhere to the values of an ethical and legal system premised, as ours is, upon a process of adjudication lawyers seldom, if ever, experience? Do the answers to these questions yield any insight for guiding reform …

Characterization Of Metal/Carbon Multilayers By Raman Spectroscopy, David D. Allred, Qi Wang, Jesus González-Hernández

Faculty Publications

Laser Raman spectroscopy has been found to be useful for characterizing amorphous semiconductor multilayers, especially the interfaces of multilayers. Recently, we have extended this technique to the characterization of magnetron sputtered multilayers commonly used as reflectors in soft x-ray optics. Unlike the multilayers previously studied which contained only semiconductors and dielectrics, these are generally semiconductor/metal multilayers. We report here on the Raman characterization of the most common class of multilayers used in soft x-ray optics, those that contain a high density metal like tungsten interspersed with layers of carbon. In all of the metal/carbon multilayers the dominate feature in the …

Design Of High Performance Soft X-Ray Windows, Raymond T. Perkins, David D. Allred, Larry V. Knight, James M. Thorne

Faculty Publications

X-ray windows are used in sources and detectors to separate the neighborhood of the x-ray generation or detection from the use environment. While each use has its own requirements, there are some principles that should be used in designing an optimal x-ray window. Because x-rays are absorbed to some extent by all materials, minimizing absorption is one criterion in preparing windows. Also, for most uses there is a pressure difference across the window so that ensuring pinhole-free structure and sufficient mechanical strength to support the differential is another criterion for window design. Traditionally, absorption is minimized by fabricating the window …

Citizenship, Alienage, And Ethnic Origin Discrimination In Employment Under The Law Of The United States, Mack Player

Faculty Publications

INTRODUCTION

This paper will survey the federal law of discrimination in employment based on ethnic origin, alienage, and citizenship. There are a number of sources of this law, many of them overlapping. The federal constitution provides some protections, but only to governmental employees or applicants. The traditional centerpiece of employment discrimination law is Title VII of the Civil Rights Act of 1964. The 1866 Civil Rights Act also provides protection which overlaps with that provided by Title VII. Finally, the recently enacted Immigration Reform and Control Act of 1986 regulates both national origin discrimination, thus duplicating the protections of Title …

Gestational Age Reporting And Preterm Delivery, Greg R. Alexander, Mark E. Tompkins, Donald A. Cornely

Faculty Publications

This study examines recent trends in the reporting completeness and quality of gestational age estimates derived from the date of the last normal menses (DLNM) as reported in South Carolina vital records from 1974 to 1985. Noteworthy improvements in the completeness of reporting emerged during this period with a decline from 31.1 percent missing information in 1974 to 6.6 percent missing in 1985. Completeness of reporting and strategies for imputing values for missing data were analyzed for their impact on the calculation of the percentage of pr?term live births. The results indicate that the underreporting of gestational age can lead …

Rheology Of Aqueous Suspensions Of Polystyrene Latex Stabilized By Grafted Poly(Ethylene Oxide), Harry J. Ploehn, J. W. Goodwin

Faculty Publications

A water-soluble carbodiimide has been used to end-graft aminated poly (ethylene oxide)(PEO) chemically onto colloidal polystyrene particles. Two particle sizes (115 and 347 nm diameter) and two PEO molecular weights (112 000 and 615 000 g mol^–1) were combined to give suspensions with four different ratios of polymer layer thickness to particle radius. Electrophoresis demonstrated that the PEO was grafted, not just adsorbed. Dynamic light scattering showed that the adsorbed and grafted layers had similar structures and that non-ionic surfactant perturbed the PEO configurations. Steady shear and oscillatory rheometry indicated that long-ranged polymeric forces between particles governed the …

A Simple Model For A Zinc/Bromine Flow Cell And Associated Storage Tanks, G. D. Simpson, Ralph E. White

Faculty Publications

A simple model for a parallel plate, zinc/bromine flow cell and associated storage tanks is presented and used to make time-dependent predictions for various quantities in the system. The model is based on a previously published algebraic model of the cell at steady-state and time-dependent, first-order differential equations for the storage tanks. The Butler-Volmer equation is used for the electrochemical reactions, and the homogeneous reaction between bromine and bromide is included. The model predictions indicate that the charging operation of a zinc/bromine battery can be significantly improved by using a storage tank with a larger residence time for the bromine …

Mathematical Modeling Of An H2s Removal Electrolyzer, Z. Mao, P. Adanuvor, Ralph E. White

Faculty Publications

A mathematical model is presented for a high temperature H₂S electrolyzer. It is shown that the maximum current in this type of a cell is determined entirely by the transport rate of sulfide ions through the separator. It is suggested that this model could be used to determine the feasibility of various designs for this electrolyzer.

Electrochemical Behavior Of Graphite And Ni-Cr Electrodes In Sodium Polysulfide In The Absence And Presence Of Hydrogen Sulfide, Z. Mao, Ralph E. White, B. Dandapani, A. Anani, S. Srinivasan, A. J. Appleby

Faculty Publications

The electrochemical behavior of graphite and Ni-Cr electrodes in sodium tetrasulfide melt has been investigated using voltammetric, chronoamperometric, and chronopotentiometric techniques in the presence and absence of hydrogen sulfide. Two continuous phases, namely, Na₂S₂ and Na₂S, are apparently formed at different potentials during the cathodic polarization. The blocking effect by these layers was much less significant on the Ni-Cr electrode than on graphite. The presence of H₂S did not appear to influence the electrode reactions, but it significantly reduced the rate of formation of the continuous phases (Na₂S₂ or Na …

A Computer Simulation Of The Oxygen Reduction Reaction In Carbonate Melts, P. K. Adanuvor, Ralph E. White, A. J. Appleby

Faculty Publications

A computer simulation of the oxygen reduction reaction in various carbonate melts has been carried out under steady-state conditions on the basis of a proposed kinetic model which takes into consideration the autocatalytic reaction involving oxygen and other reducible oxygen species in the melt, and the neutralization of oxide ions by dissolved carbon dioxide. A simulation of the presence of (physically) dissolved oxygen, in the diffusion layer region of the melt, corresponding to the possible situation in porous electrodes, causes a significant enhancement in the polarization curves, particularly in the mass-transfer control region. On the other hand, high levels of …

Estimation Of The Diffusion Coefficient And Solubility For A Gas Diffusing Through A Membrane, Michael C. Kimble, Ralph E. White, Yu-Min Tsou, R. Neal Beaver

Faculty Publications

Analysis of the data obtained by the electrochemical monitoring technique for diffusion of a gas through a membrane is considered. It is shown that combining a numerical method with a nonlinear parameter estimation technique provides a means to determine values for the diffusion coefficient and the solubility of the diffusing gas. It is shown that better accuracy can be obtained for the diffusion coefficient and solubility of this gas by using the method presented and all experimental data rather than only part of the data, as has often been done in the past.
