Spatial Evaluation Of Feedlot Runoff And Fehyd Computer Program
Spatial Evaluation Of Feedlot Runoff And Fehyd Computer Program
Journal of Spatial Hydrology
In this study 6 feedlots that are located on a watershed in North Dakota are evaluated considering the State Laws and literature with respect to their potential to cause water pollution. In the evaluation ArcView GIS software is used. Feedlots are evaluated considering the distance to surface water and aquifers, soil type, and slope-aspect criteria. The results found that all six feedlots evaluated needed runoff control facilities in order to meet all State Laws and/or literature criteria.
Nps Assessment Model: An Example Of Agnps Application For Watershed Erosion And Phosphorus Sedimentation
Journal of Spatial Hydrology
AGNPS, which is an agricultural non-point source pollution model, was used in combination with GIS tools to assess the feasibility of water quality effluent trading for phosphorus, in Morrow Lake sub-watershed, Kalamazoo, MI. GIS software packages (Arc/Info and ArcView) are used to prepare data input for the model and post process the results. The sensitivity of AGNPS parameters was evaluated to determine which most influenced phosphorus sediment loading. Evaluations were conducted to determine whether calculation processes could be simplified for rapid pollution forecasts. The results showed that pollution could be predicted by varying temporary model data (i.e. precipitation etc.) in …

The Prevention Of Infirm Or Monstrous Births, Michael T. Walton, Robert M. Fineman
Quidditas
From ancient times, humans have tried to improve reproductive outcome, that is, to give birth to healthy, beautiful babies. Both folk traditions and medical theories offered hope that inform or monstrous births could be avoided. While most efforts were ineffectual by modern standards, some may have been beneficial. It was not until well into the twentieth century that clearly demonstrable therapies were developed to improve birth outcomes. However, those therapies were almost as limited as the ancient techniques, in light of the possibilities of genetic therapy in the twenty-first century. In the following essay, we will look at the history …
A Two-Level Implementation For Lushootseed Morphology, Deryle W. Lonsdale
A Two-Level Implementation For Lushootseed Morphology, Deryle W. Lonsdale
Faculty Publications
This paper describes the implementatio of a computer system that processes Lushootseed word forms. Built on the two-level model and leveraging finite-state technology, the system is able both to parse surface forms to arives at the underlying morphemic decomposition, and to generate surface forms given such a representation. Components of the system are discussed including the lexicon architecture, rule formulation and specification, ans the word-structurer grammar. Issues relevant to processing Lushootseed are discussed including reduplication, allomorphic variation, inflectional and derivational affixation, and morphophonemic alternations.

Small-Angle X-Ray Studies Of Soot Inception And Growth, Jan P. Hessler, Soenke Seifert, Randall E. Winans, Thomas H. Fletcher
Faculty Publications
The high spectral intensity of X-rays produced by the undulator at the Basic Energy Sciences Synchrotron Radiation Center of Argonne's Advanced Photon Source has allowed us to perform small-angle X-ray scattering (SAXS) studies of the initial distribution of soot particles formed by various fuels. SAXS provides an in situ probe of the morphology of soot in the region between 1 and 100 nm and complements the ex situ technique of electron microscopy. The basic aspects of SAXS and its potential are illustrated with measurement on a laminar flame of acetylene in air. The more complex fuel toluene has been studied …
Nitrogen Transformations During Secondary Coal Pyrolysis, Haifeng Zhang, Thomas H. Fletcher
Nitrogen Transformations During Secondary Coal Pyrolysis, Haifeng Zhang, Thomas H. Fletcher
Faculty Publications
A CO/H2/O2/N2 flame was operated under fuel-rich conditions in a flat flame reactor to provide a high-temperature, oxygen-free environment to study secondary reactions of coal volatiles. The distributions of fuel nitrogen in the devolatilization products of four coals, ranging from high volatile bituminous to lignite, were obtained at gas temperatures ranging from 1159 to 1858 K. It was found that the initial nitrogen released was contained almost exclusively in the tar for all coals. Release of nitrogen from the char as light gases started at a later stage than tar nitrogen release. During secondary reactions, …
Simulation Of Coal Pyrolysis In Plasma Jet By Cpd Model, Yajun Tian, Kechang Xie, Suyu Zhu, Thomas H. Fletcher
Simulation Of Coal Pyrolysis In Plasma Jet By Cpd Model, Yajun Tian, Kechang Xie, Suyu Zhu, Thomas H. Fletcher
Faculty Publications
Reaction of coal in a plasma jet is complex and extremely rapid, and acetylene and carbon monoxide are the main products in the pyrolysis gas. Coal pyrolysis is assumed as the first step reaction when coal is injected into hot plasma jet with initial average temperature of 3700 K. Chemical percolation devolatilization (CPD) is employed first to simulate this procedure in mechanism. The calculation results indicate coal pyrolysis rate in plasma jet is very fast and the retention time of coal staying in reactor is only several milliseconds. Comparing the calculation with experiment result, it was concluded that the CPD …

13-C Nmr Analysis Of Soot Produced From Model Compounds And A Coal, Mark S. Solum, Adel F. Sarofim, Ronald J. Pugmire, Thomas H. Fletcher, Haifeng Zhang
Faculty Publications
Soot samples, including the associated organics, produced from an Illinois No. 6 coal (five samples) and two model compounds, biphenyl (three samples) and pyrene (two samples), have been studied by 13C NMR methods. The coal soot data served as a guide to selection of the temperature range that would be most fruitful for investigation of the evolution of aerosols composed of soot and tars that are generated from model compounds. The evolution of the different materials in the gas phase followed different paths. The coal derived soots exhibited loss of aliphatic and oxygen functional groups prior to significant growth …
A Non-Authoritative Educational Metadata Ontology For Filtering And Recommending Learning Objects, David Wiley, Mimi M. Recker
A Non-Authoritative Educational Metadata Ontology For Filtering And Recommending Learning Objects, David Wiley, Mimi M. Recker
Faculty Publications
Digital libraries populated with learning objects are becoming popular tools in the creation of instructional technologies. Many current efforts to create standard metadata structures that facilitate the discovery and instructional use of learning objects recommend a single, authoritative metadata record per version of the learning object. However, as we argue in this paper, a single metadata record -- particularly one with fields that emphasize knowledge management and technology, while evading instructional issues -- provides information insufficient to support instructional utilization decisions. To put learning objects to instructional use, users must examine the individual objects, forfeiting the supposed benefits of the …
Two Sides Of A River: Mormon Transmigration Through Quincy, Illinois, And Hannibal, Missouri, Fred E. Woods
Two Sides Of A River: Mormon Transmigration Through Quincy, Illinois, And Hannibal, Missouri, Fred E. Woods
Faculty Publications
The infamous extermination order issued 27 October 1838 by Missouri Governor Lilburn W. Boggs caused thousands of Latter-day Saints to flee the state and seek refuge in Illinois across the Mississippi River. Illinois, established in 1817, had high hopes for its future, but just two decades later it was smitten, like the rest of America, with the economic depression of 1837. In such a needy condition, the people Illinois welcomed the Mormon migrants for three central reasons. Financially motivated, the state viewed the Latter-day Saint influx as an opportunity to raise its population to boost the economy through the collection …

“Sweeping Everything Before It”: Early Mormonism In The Pine Barrens Of New Jersey, Stephen J. Fleming
“Sweeping Everything Before It”: Early Mormonism In The Pine Barrens Of New Jersey, Stephen J. Fleming
BYU Studies
In the summer of 1838, Elder Benjamin Winchester (fig. 1) ventured into Monmouth County, New Jersey, to preach to gospel. Winchester was the first Mormon missionary to make it into the Pine Barrens, an area so named because of its sandy, unproductive land. Soon "the news went abroad, that a Mormon preacher had made his appearance in the land." Winchester wrote, "As to [Mormon] principles, and rules of faith, the people knew nothing, except by reports... [and] the people flocked out, in crowds to hear, yet at this time, more out of curiosity than any thing else." Once Winchester began …
Alma O. Taylor's Fact-Finding Mission To China, Reid L. Neilson
Alma O. Taylor's Fact-Finding Mission To China, Reid L. Neilson
BYU Studies
In 1909, after serving as a mission president in Japan for eight years, native Utah Mormon Alma O. Taylor visited China as directed by leaders of The Church of Jesus Christ of Latter-day Saints to determine if Mormon missionaries should be sent there. Taylor did not speak Chinese, so he drew his conclusions by speaking to native English speakers living in China, often Protestant missionaries. Excerpts of Taylor's original report are published here, revealing some of the prejudices and perspectives Westerners had regarding China in the early 1900s. The author also supplies historical information about Mormon missionary work in Japan …
The Selection Of Narrow Wavebands For Optimizing Water Quality Monitoring On The Great Miami River, Ohio Using Hyperspectral Remote Sensor Data
Journal of Spatial Hydrology
Remote sensing data were successfully used to estimate spatial and temporal variation of optical water quality parameters such as chlorophyll a, turbidity and Total Suspended Solids (TSS) of the Great Miami River, Ohio. During the summer of 1999, spectral data were collected with a hand-held spectroradiometer, a laboratory spectrometer and airborne hyperspectral sensors. Approximately 80 km of the Great Miami River were imaged during a flyover with a Compact Airborne Spectrographic Imager (CASI) sensor. Approximately 10 km were imaged during a second flyover to repeat coverage of the urban and industrial influences around the city of Dayton, Ohio. Instream measurements …

Transformations Of Coal-Derived Soot At Elevated Temperature, Thomas H. Fletcher, Jim Rigby, Jinliang Ma, Brent W. Webb
Transformations Of Coal-Derived Soot At Elevated Temperature, Thomas H. Fletcher, Jim Rigby, Jinliang Ma, Brent W. Webb
Faculty Publications
Coal pyrolysis experiments were performed in the post-flame region of a CH4/H2/air flat-flame burner operating under fuel-rich conditions, where the temperature and gas compositions were similar to those found in the near-burner region of an industrial pulverized coal-fired furnace. Volatiles released from the coal particles formed a cloud of soot particles surrounding a centrally fed coal/char particle stream. Soot samples were collected from the cloud at different residence times using a water-cooled, nitrogen-quenched probe. The soot samples were then analyzed for their elemental compositions of carbon, hydrogen, nitrogen, sulfur, and (by difference) oxygen plus inorganic matter. …
Finite-Aperture Wire Grid Polarizers, Michael A. Jensen, Gregory P. Nordin
Finite-Aperture Wire Grid Polarizers, Michael A. Jensen, Gregory P. Nordin
Faculty Publications
The transmission characteristics of wire grid polarizers fabricated in finite apertures are investigated by using a three-dimensional finite-difference time-domain formulation. Specifically, the optical transmissivity and extinction ratio are characterized for a wide variety of geometrical parameters including aperture size in both dimensions, conducting wire fill factor, and polarizer thickness. A dispersive material model is used to investigate the performance of polarizers fabricated by using realistic metals at infrared wavelengths. The results indicate that the aperture dimension significantly impacts the polarizer transmission behavior and that the extinction of the unwanted polarization is often limited by depolarizing scattering that is due to …

Direct Generation Of Optical Diffractive Elements In Perfluorocyclobutane (Pfcb) Polymers By Soft Lithography, Gregory P. Nordin, J. Ballato, P. C. Deguzman, S. Foulger, H. Shah, D. Smith
Faculty Publications
Optically diffractive line gratings with 0.58- m feature sizes have been generated in 100- m perfluorocyclobutane (PFCB) polymer films by direct micromolding using only a silicon master. Strong reflectivities from the green to red portions of the visible spectrum, depending on incident beam angle, were observed with 3 dB bandwidths of approximately 30 nm. This negative mold-free technique permits, for the first time to our knowledge, feature reproduction at submicrometer size scales, eliminates several steps from conventional soft lithographic methods, and marks itself as a practical means for rapidly generating planar photonic structures that operate spectrally in the visible and …

We investigate the interfacial electrochemical properties of an aqueous electrolyte solution with discrete water molecules in slab geometry between charged atomistic electrodes. Long-range intermolecular Coulombic interactions are calculated using the particle particle particle mesh method with a modification to account for the slab geometry. Density distribution profiles and potential drops across the double layer are given for 0, 0.25, and 1 M aqueous electrolyte solutions each electrode surface charges. Results are compared qualitatively with experimental x-ray scattering findings, other computer simulation results, and traditional electrochemistry theory. The interfacial fluid structure characteristics are generally in good qualitative agreement with the conclusions …
Parallel Phylogenetic Inference, Mark J. Clement, David Mclaughlin, Quinn O. Snell, Michael Whiting
Parallel Phylogenetic Inference, Mark J. Clement, David Mclaughlin, Quinn O. Snell, Michael Whiting
Faculty Publications
Recent advances in DNA sequencing technology have created large data sets upon which phylogenetic inference can be performed. However, current research is limited by the prohibitive time necessary to perform tree search on even a reasonably sized data set. Some parallel algorithms have been developed but the biological research community does not use them because they don’t trust the results from newly developed parallel software. This paper presents a new phylogenetic algorithm that allows existing, trusted phylogenetic software packages to be executed in parallel using the DOGMA parallel processing system. The results presented here indicate that data sets that currently …
Toward Automated Abstraction For Protocols On Branching Networks, Michael D. Jones, Ganesh Gopalakrishnan
Toward Automated Abstraction For Protocols On Branching Networks, Michael D. Jones, Ganesh Gopalakrishnan
Faculty Publications
We have used various manual abstraction techniques to formally verify a transaction ordering property for an IO protocol over bus/bridge networks. In the context of network protocol verification, an abstraction is needed to reduce the unbounded number of network configurations to a small number of representative networks that can be checked using algorithmic methods. The manually derived abstraction was both brittle and difficult to validate. In this report, we discuss the need for abstraction techniques in the formal verification of protocols over networks and present our recent efforts to create an automatic abstraction technique for network protocols using predicate abstraction …

System Level Microwave Design: Radar-Based Laboratory Projects, Michael A. Jensen, David V. Arnold, Donald E. Crockett
Faculty Publications
Two laboratory projects-a Doppler radar and a synthetic aperture radar (SAR)-designed to augment traditional electromagnetics education are proposed. The projects introduce students to component and system level design and expose them to modern computer-aided design (CAD) tools, microstrip and surface mount fabrication technologies, and industry standard test equipment and procedures. Additionally, because the projects result in a working radar system, students gain new enthusiasm for the electromagnetics discipline and directly see its relevance in the engineering field. Implementation of these laboratories within the curriculum have proven to be highly motivational and educational and have even contributed to increased enrolments in …

A Dynamic Optimal Trajectory Generator For Cartesian Path Following, Edward Red
A Dynamic Optimal Trajectory Generator For Cartesian Path Following, Edward Red
Faculty Publications
This paper considers a dynamic and adaptive trajectory generator for negotiating paths using S-curves. Applying constant jerk transitions between the constant acceleration and deceleration periods of the trajectory, the trajectory will optimally transition to the desired speed setting. Optimal is defined to be the minimum time to transition from the current speed to the set speed for the move segment when jerk and acceleration are limited. The S-curve equations will adapt to instantaneous changes in speed setting and path length. An integrated motion planner will determine allowable speeds and transitional profiles based on the remaining move distance.
The Monument To Brigham Young And The Pioneers : One Hundred Years Of Controversy, J. Michael Hunter
The Monument To Brigham Young And The Pioneers : One Hundred Years Of Controversy, J. Michael Hunter
Faculty Publications
For more than a century, the Brigham Young Monument in Salt Lake City has been the center of sometimes acrimonious controversy. The idea and organization to create a monument were begun in 1891. The statue of Brigham Young was completed by Cyrus Dallin in 1893. Many delays in raising funds caused the monument not to be finished until 1900. Thereafter it often became the target of those trying to improve traffic conditions in the downtown area. In 1993, the monument was moved just north of the intersection to improve the flow of traffic. On the monuments one hundredth anniversary, "The …
Trajectory Planning For Coordinated Rendezvous Of Unmanned Air Vehicles, Timothy W. Mclain, Randal W. Beard
Trajectory Planning For Coordinated Rendezvous Of Unmanned Air Vehicles, Timothy W. Mclain, Randal W. Beard
Faculty Publications
A trajectory generation strategy that facilitates the coordination of multiple unmanned air vehicles is developed. Of particular interest is the planning of threat-avoiding trajectories that result in the simultaneous arrival of multiple UAVs at their targets. In this approach, paths to the target are modeled using the physical analogy of a chain. A unique strength of the planning approach is the ability to specify or alter the path length by adding or subtracting links from the chain. Desirable paths to the target are obtained by simulating the dynamics of the chain where threats apply repulsive forces to the chain and …
