Layered Analytical Radiative Transfer Model For Simulating Water Color Of Coastal Waters And Algorithm Development, Charles R. Bostater Jr., Lisa H. Huddleston

Ocean Engineering and Marine Sciences Faculty Publications

A remote sensing reflectance model, which describes the transfer of irradiant light within a homogeneous water column has previously been used to simulate the nadir viewing reflectance just above or below the water surface by Bostater, et al. 1,2,3 Wavelength dependent features in the water surface reflectance depend upon the nature ofthe downwelling irradiance (direct & indirect), bottom reflectance (in optically shallow waters) and the water absorption and backscatter coefficients. The latter are very important coefficients, and depend upon the constituents in water and both vary as a function ofthe water depth and wavelength in actual water bodies. This paper …

Numerical Simulation Of The Marine Atmospheric Boundary Layer Flow Over The Cape Canaveral Region And Gulf Stream Using Avhrr Sst – An Atmospheric Seabreeze Model, Charles R. Bostater, Manuel Gimond, Erik Uhlhorn, Ted Mcnally

Ocean Engineering and Marine Sciences Faculty Publications

An atmospheric mesoscale numerical model has been developed and applied to the marine atmospheric boundary layer (MABL) in the vicinity of sharp sea-surface temperature (SST) gradients. The Gulf Stream offshore ofEast Central Florida near Cape Canaveral is the region of interest. The model equations which govern atmospheric behavior are based on the basic conservation laws ofmass, momentum, and energy. A "primitive" equation formulation is used to produce preliminary predictions ofhorizontal velocity, potential temperature, and water vapor. The hydrostatic approximation is applied to the vertical momentum conservation equation and the anelastic form ofthe continuity equation is used to approximate mass conservation. …

Comparing A Hyperspectral Monte-Carlo Approach For Simulating Water Surface Reflectance Signatures Based Upon Radiative Transfer Theory: Simulating Clear Water & Caribbean Sea Bottom Types, Charles R. Bostater Jr., Manuel Gimond, Matthew Campbell

Ocean Engineering and Marine Sciences Faculty Publications

A homogeneous water column hyperspectral Monte Carlo modeling approach is compared to an analytical solution to a radiative transfer model system for irradiance. Both mathematical models and the solution approaches describe the transfer of irradiant light in a homogeneous medium. The analytical model has been previously used to describe the transfer of irradiant energy in a homogenous water column, with and without fluorescence source terms as well as a direct specular or a collimated irradiance source term. The response of the water surface reflectance under solar irradiance or an artificial collimated light source is thus modeled. Synthetic reflectance signatures generated …

Nonlinear Effects Of Physisorption On Static Friction, G.T. Gao, Xiao Cheng Zeng, Dennis J. Diestler

Xiao Cheng Zeng Publications

The effects of a physisorbed film on the force of static friction in a model contact (monatomic adsorbate confined between plane-parallel walls) were investigated by Monte Carlo simulation. At fixed coverage the friction curve (shear yield stress vs normal stress) exhibits a marked nonlinearity, which results from a competition between adsorbate–wall interactions that predominate at low loads and wall–wall interactions that set in beyond a threshold load, which increases with coverage. Previous proximal-probe and computer experiments, carried out at high coverages, see only the initial (low-load) linear portion of the friction curve.

A Simulation-Based Heuristic For Fleet Assignment, Sonia Rosario Anorga

FIU Electronic Theses and Dissertations

Integer programming, simulation, and rules of thumb have been integrated to develop a simulation-based heuristic for short-term assignment of fleet in the car rental industry. It generates a plan for car movements, and a set of booking limits to produce high revenue for a given planning horizon.

Three different scenarios were used to validate the heuristic. The heuristic's mean revenue was significant higher than the historical ones, in all three scenarios. Time to run the heuristic for each experiment was within the time limits of three hours set for the decision making process even though it is not fully automated. …

High-Performance Liquid Chromatographic Separation Of Enantiomers Of Synthetic Amino Acids On A Ristocetin A Chiral Stationary Phase, Antal Péter, Gabriella Török, Daniel W. Armstrong, Géza Tóth, Dirk Tourwé

Chemistry Faculty Research & Creative Works

A macrocyclic glycopeptide, ristocetin A, was used as chiral stationary phase for the high-performance liquid chromatographic separation of enantiomers of 28 unnatural amino acids, such as analogues of phenylalanine, tyrosine and tryptophan, and analogues containing 1,2,3,4-tetrahydroisoquinoline, tetraline or 1,2,3,4-tetrahydro-2-carboline skeletons. Excellent resolutions were achieved for most of the investigated compounds by using reversed-phase or a new polar-organic mobile phase system. The conditions of separation were optimized by variation of the mobile phase composition, temperature and flowrate. Copyright (C) 2000 Elsevier Science B.V.

Unitarized Pseudoscalar Meson Scattering Amplitudes In Three Flavor Linear Sigma Models, Joseph Schechter, Deirdre Black, Amir H. Fariborz, Sherif Moussa, Salah Nasri

Physics - All Scholarship

The three flavor linear sigma model is studied as a ``toy model'' for understanding the role of possible light scalar mesons in the \pi \pi, \pi K and \pi \eta scattering channels. The approach involves computing the tree level partial wave amplitude for each channel and unitarizing by a simple K-matrix prescription which does not introduce any new parameters. If the renormalizable version of the model is used there is only one free parameter. While this highly constrained version has the right general structure to explain \pi \pi scatteirng, it is ``not quite'' right. A reasonable fit can be made …

Looking To The Future ... Distance Education Issues In Nebraska, Nn21 Distance Education/Outreach Action Team

Nebraska Network 21: Publications

The Nebraska Network 21 (NN21) Action Team on Distance Education/Outreach has studied a variety of issues related to distance education in order to better serve the people of Nebraska. Distance education has grown rapidly in Nebraska, but is clearly in its infancy. Many important issues still are being identified and are far from understood. The possibilities of distance education are yet to be fully realized. But in a state with a small, spread-out population such as ours -- perhaps in any state -- it would seem that distance education holds great promise for making many forms of education accessible to …

My Work And Welcome To It, Stephen Hillard

Nebraska Network 21: Publications

“I want to go to graduate school in English," said my student Peter, then blurted out, "and be a professor, like you." I bit my lip not to say something deflating--at the end of the semester I didn't feel my life should be anyone's goal. I knew that he pictured the life of a professor as reading interesting books, talking about them with enthusiastic students like himself, doing research one loves, and serving on a few committees. And being paid for doing this! I didn't warn Peter that the scholarly life he aspires to is seen as a scam by …

Further Investigation Of The Time Delay, Magnification Ratios, And Variability In The Gravitational Lens 0218 + 357, A. S. Cohen, J. N. Hewitt, C. B. Moore, Deborah B. Haarsma

University Faculty Publications and Creative Works

High-precision VLA flux density measurements for the lensed images of 0218 + 357 yield a time delay of 10.1 +1.5-1.6 days (95% confidence). This is consistent with independent measurements carried out at the same epoch by Biggs and colleagues in 1999, lending confidence to the robustness of the time delay measurement. However, since both measurements make use of the same features in the light curves, it is possible that the effects of unmodeled processes, such as scintillation or microlensing, are biasing both time delay measurements in the same way. Our time delay estimates result in confidence intervals that are somewhat …

Cooperative & Nebraska “Blue Sky” Statutes, J. David Aiken

Cornhusker Economics

Cooperative fever is sweeping Nebraska. Agricultural producers are looking for ways to add value to what they produce, often through forming “new generation” cooperatives or by forming limited liability companies (LLCs). New generation cooperatives differ from traditional cooperatives in that new generation cooperatives typically (1) have closed membership and (2) process goods produced by co-op members. New generation cooperatives are more like citrus and other fruit cooperatives that have existed in other parts of the country. The Nebraska Unicameral is providing financial assistance to assist developing these kinds of value-added efforts through LB1348, the “Agricultural Opportunities and Value-Added Partnerships Act.” …

Quarantine And Health Screening Protocols For Wildlife Prior To Translocation And Release Into The Wild, Michael H. Woodford

Zoonotics and Wildlife Disease: Publications

In recent years the translocation and release into the wild of wild-caught and captive-bred wild animals (mammals, birds, reptiles, amphibians and fish) has become a common practice, ostensibly for rehabilitation or conservation purposes. These wild animals comprise many varied taxa and the objectives of translocation and release may include:
(1) reintroducing a species that has become extinct in its natural range;
(2) restocking or reinforcing a population which has become depleted; and
(3) rehabilitating wild animals and birds which have been illegally captured and subsequently confiscated by Customs or national wildlife authorities. Welfare organizations also receive sick and injured wild …

Gender Differences In The Effect Of Child Maltreatment On Criminal Activity Over The Life Course, Ryan E. Spohn

Criminology and Criminal Justice Faculty Publications

This paper adds to a growing body of knowledge regarding the criminal consequences of childhood victimization. A prospective research design is used to compare a group of maltreated youth to a matched control group in order to determine the extent to which child abuse and neglect influence both juvenile delinquency and adult crime. Controlling for race and sex, abused and neglected children are more likely to have a juvenile arrest record. In addition, controlling for involvement in juvenile crime, child maltreatment also influences adult criminality. Motivated by the findings of qualitative studies focusing on female offenders, I examine gender differences …

Phase Diagram Of Three-Dimensional Dynamical Triangulations With A Boundary, Simon Catterall, Simeon Warner, Ray Renken

Physics - All Scholarship

We use Monte Carlo simulation to study the phase diagram of three-dimensional dynamical triangulations with a boundary. Three phases are indentified and characterized. One of these phases is a new, boundary dominated phase; a simple argument is presented to explain its existence. First-order transitions are shown to occur along the critical lines separating phases.

Constant Mean Curvature Surfaces With Three Ends, Karsten Grosse-Brauckmann, Robert Kusner, John M. Sullivan

Robert Kusner

We announce the classification of complete almost embedded surfaces of constant mean curvature, with three ends and genus zero. They are classified by triples of points on the sphere whose distances are the asymptotic necksizes of the three ends.

Shaq, Lsu, The Degree V. Education, Richard C. Crepeau

On Sport and Society

Over the past several days much has been written about the graduation of Shaquille O'Neal from Louisiana State University. Indeed the event has been the butt of many jokes, one of which Shaq generated himself when he told people he was working on his degree at Learn Slow University. He now says that LSU means Love Shaq University.

Optically Induced Periodic Structures In Smectic-C Liquid Crystals, Antal Jákli, A. Vajda, E. Benkler, Janossy, Peter Palffy-Muhoray

Antal Jakli

We explore periodic structures of smectic-C (SmC) liquid crystals, induced optically by a polarization grating. The studied cells contain a passive surface of rubbed polyimide and an active photosensitive substrate of ate-dye doped polyimide. In a nematic phase the director field can be periodic independent of the angle between the grating vector and the rubbing direction. In the SmA phase periodic structure can be induced only by layer undulations. The SmC behaves similarly to the nematic phase, but the director can rotate only on a cone, which results in a more complex geometry. The periodic pattern is superimposed with four …
