Great Plains Workshop Held To Prepare For Usarray Deployment, Mary S. Hubbard, S. S. Gao, K. H. Liu, K. E. Nicolaysen, C. G. Oviatt

Geosciences Faculty Publications

Relative to most parts of North America, the Great Plains region, which is bordered by the Rocky Mountain Front on the west and the Mississippi River on the east, has been understudied in terms of the structure, formation, and evolution of the underlying crust, mantle, and core. The anticipated arrival of the USArray portable seismic stations, which will cover the entire United States regardless of surface geology and tectonic activities, and the deployment of the accompanying flexible array stations and the permanent seismic stations in this area, will fill this gap and address numerous problems related to the structure and …

The National Wildlife Strike Database For The Usa: 1990 To 2002 And Beyond, Sandra E. Wright, Richard A. Dolbeer

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

The National Wildlife Strike Database for Civil Aviation in the USA became operational in 1995 with the initiation of data entry of all strikes beginning in 1990. Since 1995, approximately 46,600 reported strikes from 1990-2002 involving civil aircraft in the USA or for USA carriers in foreign countries have been entered into the database. About 97% of the reported strikes have involved birds and 3% have been with mammals or reptiles. Over 2,000 reported strikes have indicated substantial damage to the aircraft. The database has proven to be an extremely useful source of objective information on the extent and nature …

Through A Bird’S Eye – Exploring Avian Sensory Perception, Robert C. Beason

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

For too many birds their environment includes airfields and aircraft. Knowing avian sensory abilities, researchers can design experiments and develop new devices and techniques to deter birds from aircraft on and away from airfields. How birds perceive the world about them determines many choices, including foraging, predator avoidance, and flight. Most experiments to investigate the sensory abilities of birds have been developed and analyzed using only human sensory capabilities, which often differ markedly from those of birds. My objective is to review and synthesize what is known and what is unknown about avian sensory capabilities. Compared with humans, birds can …

Risk-Based Modeling To Develop Zoning Criteria For Land-Use Near Canadian Airports, Rolph A. Davis, Terry Kelly, Richard Sowden, Bruce Mackinnon

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

Land development in the vicinity of airports often leads to land-use that can attract birds that are hazardous to aviation operations. For this reason, certain forms of land-use have traditionally been discouraged within prescribed distances of Canadian airports. However, this often leads to an unrealistic prohibition of land-use in the vicinity of airports located in urban settings. Furthermore, it is often unclear that the desired safety goals have been achieved. This paper describes a model that was created to assist in the development of zoning regulations for a future airport site in Canada. The framework links land-use to bird-related safety-risks …

Towards Multi-Stakeholder Cooperation In Wildlife Management, Brian E. Henshaw

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

Wildlife management at airports presents a myriad of challenges. Familiar to many in the field, is the outwitting of wily coyotes, the outsmarting of persistent birds and the outflanking of troublesome deer. Deterrents to barriers, dogs to pyrotechnics, habitat management to habitat removal, an array of increasingly effective measures can be used as part of integrated wildlife management programs to meet the challenge of increasing suburban wildlife populations and their interactions with air traffic. On or off the airfield, the objectives of all stakeholders will not be consistent with best management practices for wildlife management. This is increasingly likely outside …

Are Birds Scared By Rotating Mirrors?, Thomas W. Seamans, Scott C. Barras, Zachary J. Patton

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

Blackbirds (Icteridae) create human health and safety concerns when roosting in large numbers near airports or other urban areas. Therefore, there is considerable demand for effective nonlethal techniques to deter these birds. We tested the effectiveness of rotating mirrors (Peaceful Pyramid®) to keep blackbirds away from decoy traps. Mirrors were in place on traps for 5 consecutive days with control traps having similar a device in place but without mirrors. The total number of birds captured in traps with clear mirrors and control traps did not (P = 0.62) differ. When red mirrors were used, the total number of birds …

Fear And Loathing: The Modulatory Effect Of Stress On Memory Formation And Its Wildlife Management Implications, Arla G. Hile

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

An ongoing challenge for wildlife managers is that target species habituate to or forget about hazing, even though the animals must be somewhat stressed by the hazing. Although stress and efficient memory formation/retrieval are considered to be incompatible, research suggests that the effect of stress on memory is complex. Mild and intense stress can impair memory formation and chronic stress can disrupt memory retrieval. Intermediate stress, however, actually enhances the formation of new memories, particularly long-term memories. Unfortunately, these conclusions are based data from only a very few domesticated species under highly controlled conditions. In nature the variation in baseline …

Risk Analysis Of High-Speed Aircraft Departures Below 10,000 Feet, Bruce Mackinnon, Richard Sowden (Capt.), Terry Kelly

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

This paper abridges a Canadian study that examined bird-related safety risks to aircraft climbing to 10,000 feet MSL (mean sea level) at speeds in excess of 250 kias (knots indicated airspeed). The study employed a risk-based framework to examine ornithological information, bird strike data, aircraft-certification standards, aircraft climb performance and aircraft flight profiles. Foremost among its findings, the study determined that populations of high-risk bird species are increasing, that many of these species flock at the altitudes in question, and that aircraft exposure to risk will increase in part because of projected increases in aircraft movements. Examining the appropriateness of …

An Automated Acoustic System To Monitor And Classify Birds, C. Kwan, K. Ho, G. Mei, Y. Li, Z. Ren, R. Xu, G. Zhao, M. Stevenson, V. Stanford, C. Rochet

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

Collisions between aircraft and birds have become an increasing concern for human health and safety. More than four hundred people and over four hundred aircraft have been lost globally in recent years, according to a FAA report. To minimize the number of birdstikes, microphone arrays have been used to monitor birds near the airport or some critical locations in the airspace. However, the range of existing arrays is only limited to a few hundred meters. Moreover, the identification performance in low signal-to-noise environment is not satisfactory. Under the support of the US Air Force, Intelligent Automation, Incorporated (IAI) and the …

The Relationship Of Military Aircraft Activity To Raptors In Central Labrador, Dawn K. Laing, David M. Bird, Tony E. Chubbs, Maj. Gary Humphries

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

Central Labrador is a notable breeding area for Osprey (Pandion haliaetus) and Bald Eagles (Haliaetus leucocephalus). It is also the location of the North Atlantic Treaty Organization’s (NATO) Low level Training Area (LLTA) for fighter aircraft, covering an area of approximately 130,000 km2 over Labrador and north-eastern Québec. Currently, military aircraft based in Goose Bay, Labrador annually conduct 5,000-7,000 sorties and are permitted to conduct up to 18,000 per flying season (DND 1995). The interaction between the two is frequently fatal for the bird and potentially so for the aircraft and pilot. Since the early 1990s, the Department of National …

Application Of Gis Technologies To Wildlife Management At Dfw Airport, Edwin E. Herricks, Jonathan R. B. Fisher, Curt Kuehner, Michael J. Hovan

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

As part of a continuing FAA research program in wildlife hazard assessment and management at airports, a GIS Technical Element – DFW was developed for the Wildlife Hazard Advisory System (WHAS). For the DFW GIS data layers were obtained from public sources and supplemented with airport specific information. Data themes were developed to support general analysis of wildlife habitat on the AOA and adjacent airport property, and analysis was extended to a distance of 25 miles from the airport to accommodate all aircraft in high risk airspace. Over 10,000 wildlife report records were integrated with data on birdstrikes and runway …

A Model For Assessing Bird Strike Risk At Proposed New Airports, Jenny Bell, Niall H. K. Burton, Richard Walls, Andy J. Musgrove, Mark M. Rehfish, John Allan, George Wattola

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

There are many criteria which need to be assessed when carrying out site selection for new airport developments. One of those which should be assessed is prospective bird hazard and bird strike risk – unfortunately, this is rarely considered as a factor. One reason for this may be the lack of available methodology for such work. This paper presents the methodology used during a recent hazard assessment for a proposed new airport for London. The methodology builds on previously described risk assessment techniques, which were developed for operational airports. It allows an assessment of the likelihood of bird strikes to …

Gis And Wildlife Management Activities At Airports, Shelley Gray

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

Wildlife observations collected over time at a US Air Force Base (AFB) have been visually displayed through Geographic Information System (GIS) technology. By continuing to expand upon the capabilities of GIS, USDA Wildlife Services has been able to manage the Seymour Johnson AFB airfield and surrounding areas in a practical manner. A Wildlife Hazard Assessment of the AFB used GIS to clearly display the location of birds and mammals observed on the airfield. Baseline themes of natural features (i.e. rivers, woodlands, etc.) were related to wildlife observations to determine areas requiring management. Additionally, GIS has been a useful tool to …

Seismicity In The Vicinity Of Yucca Mountain, Nevada, For The Period October 1, 2001 To September 30, 2002, David H. Von Seggern, Kenneth Smith, James N. Brune, Richard Quittmeyer, Amy J. Smiecinski

Publications (YM)

Starting on October 1, 1995, the monitoring of seismicity within the southern Great Basin near Yucca Mountain was performed with a new digital network. This network features three-component recording with 24-bit A/D conversion in the field. Continuous data are collected at 20 sps, and event triggered windows are collected at 100 sps. A seismic bulletin of events is made by automatically associating triggers among stations, classifying the local earthquake events, and locating the earthquakes and computing their magnitudes with conventional methods. This report covers the operational and seismic results of the seventh year (FY02) of the digital network monitoring. The …

Riemann And Edalat Integration On Domains, Jimmie D. Lawson, Bin Lu

Faculty Publications

The main result of this paper is that the domain-theoretic approach to the generalized Riemann integral first introduced by Edalat extends to a large class of spaces that can be realized as the set of maximal points of domains. The approach is based on the theory of a Riemann-Stieltjes type integral on a topological space with respect to a finitely additive measure. We develop the theory of this integral for a bounded function f defined on the maximal points of a continuous domain and show that it gives an alternate approach to the Edalat integral. © 2002 Elsevier B.V.

Minimal K-Rankings And The A-Rank Number Of A Path, Victor Kostyuk, Darren Narayan, Victoria Shults

Articles

Given a graph G, a function f: V(G) -> {1, 2, ..., k} is a k-ranking of G if f(u) = f(v) implies every u - v path contains a vertex w such that f(w) > f(u). A k-ranking is minimal if the reduction of any label greater than 1 violates the described ranking property. The a-rank number of G, denoted u,(G) equals the largest k such that G has a minimal k-ranking. We establish new results involving minimal rankings of paths and in particular we determine u(Pn), a problem suggested by Laskar and Pillone in 2000. We show u(Pn) = …

Laboratory Studies Of Gas Permeability Of Frozen Soil, Qing Lin

Theses (Unassigned)

A preliminary investigation on the gas permeability of frozen soil was conducted in this study. A unique low-temperature permeability testing system was designed and developed. Widely accepted standard procedures were followed to prepare soil samples. A number of experiments were conducted in a cold chamber with controlled temperature. The impact of several parameters upon the gas permeability of frozen soil was investigated. The experiment results indicated that among the parameters examined, moisture content had the most significant impact on the gas permeability of frozen soil and the effect of temperature was less significant than that of moisture content. It was …

Reproductive Decisions By Black Brant: Mechanisms To Synchronize Hatch And Spatial Variation In Growth Rates Of Goslings, Christopher Andrew Nicolai

Biological Sciences

I investigated two aspects of reproductive decisions in Black Brant: synchronous hatch within clutches and areas in which to rear their broods. It has been hypothesized that Anatidae facilitate a synchronous hatch through vocalizations among embryos within the same clutch. I performed manipulative experiments in which variation was controlled for both genetic and incubation pattern sources in incubation period length. Our results suggest that vocalizations are not responsible for a synchronous hatch, and I suggest that inherent properties of the eggs themselves are responsible for a synchronous hatch. Additionally, I compared gosling growth rates from areas of low nest densities …

Analysis And Control Of Time-Periodic Systems With Time Delay Via Chebyshev Polynomials, Haitao Ma

Engineering

A technique for studying the transient response and the stability properties of dynamic systems modeled by delay-differential equations (DDEs) with time-periodic parameters is presented in this thesis. The approach is based on an orthogonal polynomial expansion (shifted Chebyshev approximation). In each time interval with length equal to the delay period, the dynamic system can be reduced to a set of linear difference equations for the Chebyshev expansion coefficients of the state vector in the previous and current intervals. In this way, the transient response of the dynamic system can be directly obtained and the stability properties are found to be …

Estimation Of Operation Time For Soil Vapor Extraction Systems, Trevor C. White

Engineering

Since the inception of Soil Vapor Extraction (SVE) as a viable contaminated soil restoration strategy, operators of these systems have struggled with determining the best date to terminate operation of their systems. Using principles of soil-gas flow and mass transport through unsaturated soils, stochastic hydrogeology, uncertainty analysis, and a cost/risk decision model, a procedure that can determine the appropriate time to discontinue operation of SVE systems was developed. Modeling of physical characteristics and determination of mass removal of a SVE system was accomplished using statistical realizations of permeability (uncertainty model) and a 2D advective-dispersive finite element vapor transport program (VapourT). …

Numerical Modelling Of Electromagnetic Wave Propagation In A Hallway, Arun Venkatasubramanian

Engineering

This research involves the numerical modelling of electromagnetic wave propagation, (1) to calculate the electric and magnetic fields at any point in a hallway for a known transmitter and receiver antenna pattern and orientation and (2) to determine the wave normal direction of the electromagnetic wave using the electric fields calculated in (1). The results of the numerical simulation are compared with measurements for two hallways. Both the transmitter and receiver employ vertically oriented /4 dipoles operating at 2.4 GHz. Our work has led to the following new results: (1) The calculated signal power varies as 1/r² whereas the measured …

Phase Behavior Analysis Of Gas-To-Liquid (Gtl) Products For Transportation Through Trans Alaska Pipeline System, Amit Sharma

Engineering

The natural gas reserves on the North Slope of Alaska can be converted to a high premium liquid product using the Gas-to-Liquids (GTL) technology. The GTL product can be transported from the North Slope of Alaska to the southern port of Alaska through the Trans Alaska Pipeline system (TAPS). In this study, experimental work done in the laboratory to determine the phase behavior and fluid properties of the GTL products and their blends with North Slope crude oil has been presented. To transport the fluid, it becomes necessary to investigate the phase behavior of the fluid at pipeline conditions. Bubble …

Analytical And Numerical Studies On Macro And Micro Scale Heat Sinks For Electronics Applications, Devdatta P. Kulkarni

Engineering

From the practice in computer industry the standard approach for electronics cooling is fan-cooled heat sinks. We developed thermal models for forced convection heat sinks. An Intel Pentium ill chip has been adopted as a preliminary design case to develop necessary equations. We found the heat dissipated from the aluminum heat sink, based upon different modes of airflow over the fins. We also considered radiation heat transfer. We performed transient heat transfer analysis to determine the time to attain the steady state temperature for the whole system for macro and micro scale also. Next, we refined our one-dimensional analytical convection …

Modeling Of Permafrost And Gas Hydrate Stability Zone Within Alaskan Arctic Shelves And Continental Margins, Sergei I. Pokrovsky

Geosciences

A mathematical model was used to determine the behavior of the thermal regime and temperature and pressure conditions due to climate and sea level variations of the gas hydrate stability zone formation at four sites within the Alaskan Arctic Shelf. Two soil types, coarse-grained and fine-grained, and three types of programs were used. The programs were distinguished by whether or not they took unfrozen water and latent heat into account. Simulations suggest the presence of subsea permafrost in a vast area of shelf near Prudhoe Bay. Near Barrow and Lonely subsea permafrost extends up to several tens of kilometers offshore, …

Phase Changes In Internally Mixed Maleic Acid/Ammonium Sulfate Aerosols, Sarah D. Brooks, Rebecca M. Garland, Matthew E. Wise, Anthony J. Prenni, Melinda Cushing, Erika Hewitt, Margaret A. Tolbert

CUP Faculty Research

A temperature controlled flow tube system equipped with Fourier transform infrared (FTIR) detection of particle phase and relative humidity was used to measure the deliquescence and efflorescence of ammonium sulfate, maleic acid, and internally mixed maleic acid/ammonium sulfate particles. Our results indicate that maleic acid aerosols begin to take up water starting at a low relative humidity, ∼20%, and continue the constant uptake of water until the final deliquescence relative humidity (DRH), 89%, is reached. Internally mixed particles containing maleic acid and ammonium sulfate were found to deliquesce at a lower relative humidity (RH) than either of the pure species. …
