High Return Rates For Relocated Red-Tailed Hawks: Preliminary Findings At Portland International Airport, Julie Fukuda, Carole Hallett

Bird Strike Committee-USA/Canada Joint Annual Meeting: 2nd (2000)

Pacific Habitat Services, Inc. (PHS), under contract with the Port of Portland (Port), trapped, banded, and relocated red-tailed hawks at the Portland International Airport (PDX) in Portland, Oregon, beginning in October 1999. Although the Port has a program to deal with wildlife hazards to aircraft operations, raptor prey base management and hazing hadn’t effectively reduced wildlife hazards. Nineteen birdstrikes occurred in September, 1999. Prior to this season, birdstrikes ranged from 0 to 11 within a one-month period. Thus, immediate action was needed to reduce raptor abundance on the airfield. In fall and winter of 1999, PHS captured and relocated fifteen …

Effect Of The Direction Of The Blast On Vegetation Recovery Within The Zone Of Devastation Created By The May 18, 1980 Eruption Of Mount St. Helens, Washington, Dmitri Barkovsky

All-Inclusive List of Electronic Theses and Dissertations

A number of different remote sensing techniques were used to analyze Landsat TM image data in order to study vegetation recovery patterns at three locations within the zone of devastation of Mount St. Helens (MSH). Prior to the May 18, 1980 eruption, the vegetation in the area ofMSH was characterized by mature coniferous forest disturbed only by a few clearcuts, according to analysis of Landsat MSS data. As a result of the MSH eruption, more than 600 sq. km of the area predominantly north of the volcano were severely devastated by a number of volcanic events such as phreatic explosions, …

Comparative Analysis Of Thebes And Kirk Lithic Technology And Home Range Implications In Southwestern Indiana, Mark E. Cantin

All-Inclusive List of Electronic Theses and Dissertations

Early Archaic populations are typically characterized as highly mobile forager groups with expansive home ranges, though little distinction is made between systems of penecontemporaneous groups. This thesis will investigate and compare home range size, technology, and material type and quality selection practices between two Early Archaic populations as manifested by Kirk and Thebes Cluster projectile points in a data set recovered from southwestern Indiana. The mechanisms behind and the relationships between chert selection and mobility will be shown as a complex feedback loop. As such, the role of curation, embeddedness, and risk management in technological organization and the potential influence …

Telemip: Telecommunications-Enhanced Mobile Ip Architecture For Fast Intradomain Mobility, Subir Das, Archan Misra, Prathima Agrawal, Sajal K. Das

Research Collection School Of Computing and Information Systems

This article first surveys existing protocols for supporting IP mobility and then proposes an extension to the mobile IP architecture, called TeleMIP. Our architecture attempts to achieve smaller handoff latency by localizing the scope of most location update messages within an administrative domain or a geographical region. TeleMIP is intended for use in evolving third-generation wireless networks, and introduces a new logical entity, called the mobility agent, which provides a mobile node with a stable point of attachment in a foreign network. While the MA is functionally similar to conventional foreign agents, it is located at a higher level in …

The geographical problem addressed in this study was to reconstruct the paleogeography of the western Beteiha Plain, located between Bethsaida and the Sea of Galilee and determine its sedimentologic and paleogeomorphologic character. Grain size analysis of sediments, along with sediment color was used to reconstruct the landscape and identify areas such as estuaries or lagoons.

Sediment samples were collected throughout the Beteiha Plain at selected locations. Excavation and collection was accomplished with hand-driven core equipment and backhoe trenches.

The multidisciplinary approach used in this project included fieldwork for sediment collection, laboratory analysis for the production of the data necessary to …

Identity, Conflict And Cooperation In International River Basins, Jack V. Kalpakian

Graduate Program in International Studies Theses & Dissertations

This dissertation tests the hypothesis that water disputes cause serious conflict within and between states. It uses a structured case study approach to see whether there is a link between the independent and dependent variables. It also considers the effect of other variables on serious conflict. Specifically it addresses the effects of national identity and the othering process on conflict. The three case studies are built around rivers in the drier parts of the world. This biases the dissertation towards affirming the established mainstream hypothesis which states that water disputes cause serious conflict. In all three cases, historical animosities and …

Routing Optimization Through Computer-Aided Simulation, Madhusudhan Akundi

Electrical & Computer Engineering Theses & Dissertations

Routing has always been a challenging field, and the various techniques of mathematics and operations research have been developed. For commercial organizations, routing has begun to receive extensive attention because of the savings gained in terms of time, money, personnel, and the transportation fleet by developing optimized routing networks. Until recently, it was difficult to develop optimized networks due to the computational difficulties of the problem. However, with the advancement in computer technology and processing speeds, it has become possible to simulate a large number of routing scenarios and determine optimal solutions for a given set of constraints. Not only …

Re-Engineering Structures From Web Documents, Moh Chuang Hue, Ee Peng Lim, Wee-Keong Ng

Research Collection School Of Computing and Information Systems

To realize a wide range of applications (including digital libraries) on the Web, a more structured way of accessing the Web is required and such requirement can be facilitated by the use of XML standard. In this paper, we propose a general framework for reverse engineering (or re-engineering) the underlying structures i.e.,the DTD from a collection of similarly structured XML documents when they share some common but unknown DTDs. The essential data structures and algorithms for the DTD generation have been delveloped and experiments on real Web collections have been conducted to demonstrate their feasibilty. In addition, we also proposed …

Shifts In Mid- To Late-Holocene Anion Composition In Elk Lake (Grant County, Minnesota): Comparison Of Diatom And Ostracode Inferences, Jasmine E. Saros, Sherilyn C. Fritz, Alison J. Smith

Department of Earth and Atmospheric Sciences: Faculty Publications

The fossil diatom record from Elk Lake (Grant County, Minnesota) was used to reconstruct salinity and brine type between 2640 and 4645 ¹⁴C yr BP. This lake was selected for a brine-type reconstruction because a previous study using fossil-ostracode assemblages indicated a shift in anion composition during the mid-Holocene (Smith et al., 1997). Salinity was reconstructed using a transfer function developed for the Northern Great Plains (NGP) of North America; the reconstruction revealed that salinity was higher (1.5–6.2 g l⁻¹) between ~4000 and 4645 14C yr BP and dropped to 0.35–1.2 g l−1 after 4000 14C yr …

Remote Sensing And Geographic Information Systems For Decision Analysis In Public Resource Administration: Case Study In A Southwestern Watershed, William G. Kepner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alternative futures analysis is a scenario-based approach to regional land planning that attempts to synthesize existing scientific information in a format useful to community decision makers. Typically, this approach attempts to investigate the impacts of several alternative sets of choices preferred by representative stakeholder groups relative to selected environmental or economical endpoints. Potential impacts from each of the scenarios are compared to current conditions of the region in terms of a set of processes that are modeled within a geographic information system. Future conditions are generally examined from the perspective of a recent baseline condition (versus empirically determined using a …

The Sequence Stratigraphy Of The Middle Cambrian Wheeler Formation In The Drum Mountains Of West Central Utah, Loren P. Schneider

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The majority of the Middle Cambrian Wheeler Formation in the Drum Mountains was deposited during a single 3^rd order sequence. Superimposed onto this sequence are three indistinct 4^th order cycles and twenty distinct 5^th order cycles. These higher order cycles were likely deposited within short intervals of geologic time (204 to 405 ky).

The lower sequence boundary zone occurs within the Swasey Formation. The Transgressive Surface is the contact between the Swasey and Wheeler Formations. The Maximum Flooding Surface is located near the top of the lower Wheeler Formation, which also approximates the base of the Ptychagnostus …

The Age Of The Woolly Rhino From Dream Cave, Derbyshire, Uk, Donald A. Mcfarlane, Joyce Lundberg, Derek C. Ford

WM Keck Science Faculty Papers

The Dream Cave woolly rhinoceros, Coelodonta antiquitatis, is a "classic" specimen of a "cold-stage" fossil fauna from central England. The find was illustrated and described by Dean William Buckland in his seminal tome Reliquiae Diluvianae (1823) during the first half of the 19th century, and made a significant contribution to the development of Buckland's views on the origin of extinct and extirpated fossil vertebrates. The report presents the first, albeit indirect, radiometric dates on the specimen, and argues that the animal fell into the cave just before 37,000 years BP, during the middle of Marine Isotope Stage 3 Interstadial (41 …

Muir Center Newsletters (1981-2015)

NEWSLETTER M Transcendentalist by L. Mikel Vause, Weber State University he term "transcendentalist" evokes an interesting image. Generally when one thinks of a transcendentalist, the image of a little brown-skinned mystic, sitting in lotus position chanting "ommm" comes to ihind. Although American transcendentalism certainly does have Far Eastern roots, one ascribing to that title is Br more likely to be found tramping around the back country rather than curled up on a mat contemplating the ilssence of existence. The founder of American transcendentalism is Ralph Waldo Emerson, "The Sage of Concord." It was Emerson who, with the publication of Nature …

Multiple Source Pools And Dispersal Barriers For Galápagos Plant Species Distribution, J. Alan Yeakley, John F. Weishampel

Environmental Science and Management Faculty Publications and Presentations

We reexamined geographic factors explaining the number of plant species on islands in the Galápagos Archipelago. We hypothesized that plant species richness (S) was related to the number of source pools and that plant species dispersal preferentially followed direct, oceanic pathways. To test different dispersal pathways from multiple source pools, the total number of islands within a given dispersal radius (i) was posed as the sum of the number of line-of-sight islands (C_i) and of the number of islands without line-of sight connection (B_i). In partial regression analyses, controlling for nearest island area (A₂) …

Wavelength Modulation Spectroscopy Of Water Vapor And Line Center Stabilization At 1.462 Μm For Lidar Applications, Colleen Marie Fitzgerald

Electrical & Computer Engineering Theses & Dissertations

Wavelength modulation spectroscopy was employed to investigate water vapor absorption lines in the 1.462 µm wavelength region using an external-cavity diode laser. These measurements were necessary in the development of a lidar (light detection and ranging) instrument for differential absorption measurement of the concentration and movement of water vapor in the Earth's atmosphere. Differential absorption measurements require that the laser frequency remain stable throughout the duration of the measurement. To ensure this stability, the laser output wavelength is monitored and a feedback control loop set up to minimize laser line drift. Three lines were investigated in the 1.462 µm region. …

A Neural Network Solution To Predicting Wind Speed At Cape Canaveral’S Atlas Launch Pad, Kenneth P. Cloys

Theses and Dissertations

This thesis demonstrates the potential for using time-delay neural networks to provide Launch Weather Officers (LWOs) at 45th Weather Squadron (45 WS) with advance warning of wintertime (November-March) peak wind speeds at the Atlas launch pad. The 45 WS provides weather support to the United States space program at Cape Canaveral Air Station, NASA's Kennedy Space Center, and Patrick Air Force Base. Due to the complex wintertime environment produced by the effects of friction and instability, 45 WS LWOs consider wintertime launch pad winds their toughest forecast challenge. Neural networks were developed, trained, and tested using observations of wintertime peak …

Modeling The Growth Dynamics Of Antarctic Krill Euphausia Superba, Eileen E. Hofmann, Cathy M. Lascara

CCPO Publications

A time-dependent, size-structured, bioenergetically based model was developed to examine the growth dynamics of Antarctic krill Euphausia superba 2 to 60 mm in size. The metabolic processes included in the model are ingestion, a baseline respiration, respiratory losses due to feeding and digestion, and an activity-based respiration factor. The total of these processes, net production, was used as the basis for determining the growth or shrinkage of individuals. Size-dependent parameterizations for the metabolic processes were constructed from field and laboratory measurements. Environmental effects were included through time series of pelagic phytoplankton concentration that were derived from data sets collected west …

Collection Of Detonation Signatures And Characterization Of Spectral Features, Jay A. Orson

Theses and Dissertations

The remote observations of the temporal and spectral characteristics of the infrared (IR) emissions from exploding ordnance have been correlated with explosion conditions. A Bomem MR-154 Fourier Transform Interferometer with two detectors, InSb and HgCdTe, and a 75 mrad telescope was used to record spectra in the 1.3 - 20 µm range. Data was collected at spectral resolutions of 16 cm^-1 and 4 cm^-1 and temporal resolutions of 0.045 s and 0.123 s respectively. Two field tests were conducted: (1) a set of dynamic drop explosions and (2) a series of static detonations. In most events, the temporal …

A Java Universal Vehicle Router In Support Of Routing Unmanned Aerial Vehicles, Robert W. Harder

Theses and Dissertations

Unmanned Aerial Vehicles (UAVs) help the military gather information in times of peace and war. During a mission, typically 100 sites or more, a UAV will frequently be re-tasked to visit a pop-up threat, leaving the operator to determine the best way to finish the day's list of sites after the re-tasking. I develop a prototype application to serve the needs of a specific customer, the 11th Reconnaissance Squadron, by helping them preplan missions and dynamically re-task UAVs. This prototype application is built on a reusable airframe router called the core AFIT Router, which can later be added to more …
