Immaccs: An Experimental Multi-Agent C2 System, Jens G. Pohl, Anthony A. Wood, Kym Jason Pohl

Collaborative Agent Design (CAD) Research Center

The Integrated Marine Multi-Agent Command and Control System (IMMACCS) is a multi-agent, distributed software system, designed to provide a Common Tactical Picture (CTP) with integrated and meaningful decision-support facilities to authorized operators at any access node. IMMACCS has been implemented as a three-tier architecture that distinguishes between information, logic and presentation. It utilizes an object-serving communication facility with subscription and multi-casting capabilities that is based on the Common Object Request Broker Architecture (CORBA). With an emphasis on application, IMMACCS was designed and implemented in concert with its military users as an integral component of experiments conceived by the Marine Corps …


Observational Constraints On The Internal Velocity Field Of Quasar Emission-Line Clouds, Mark Bottorff, Gary J. Ferland, Jack Baldwin, Kirk Korista Oct 2000

Observational Constraints On The Internal Velocity Field Of Quasar Emission-Line Clouds, Mark Bottorff, Gary J. Ferland, Jack Baldwin, Kirk Korista

Physics and Astronomy Faculty Publications

This paper addresses the question, what does the spectrum of a typical quasar reveal about the velocity structure within its broad emission line region clouds? Turbulent (i.e., nonthermal) broadening of spectral lines can be due to macroturbulence or microturbulence. Microturbulence affects line formation and the emitted spectrum and may be required to account for the observed smoothness of the line profiles. The velocity field is crucial since it addresses the fundamental nature of the individual clouds and the global structure of the active galactic nuclei (AGNs) environment. For example, stellar winds or magnetically confined blobs might be highly microturbulent, requiring …


Photochemical Production Of Gas Phase No X From Ice Crystal No3 −, R E. Honrath, S Guo, Matthew C. Peterson, M P. Dziobak, Jack E. Dibb, Matthew Arsenault Oct 2000

Photochemical Production Of Gas Phase No X From Ice Crystal No3 −, R E. Honrath, S Guo, Matthew C. Peterson, M P. Dziobak, Jack E. Dibb, Matthew Arsenault

Earth Sciences

Recent measurements have demonstrated that sunlight irradiation of snow results in the release of significant amounts of gas phase NOx (NO+NO2). We report here the results of a series of experiments designed to test the hypothesis that the observed NOx production is the result of nitrate photolysis. Snow produced from deionized water with and without the addition of nitrate was exposed to natural sunlight in an outdoor flow chamber. While NOx release from snow produced without added NO3 was minimal, the addition of 100 µM NO3resulted in the release …


Direct Measurement Of The W Boson Width In Pp̅ Collisions At √S = 1.8 Tev, T. Affolder, Kenneth A. Bloom, Collider Detector At Fermilab Collaboration Oct 2000

Direct Measurement Of The W Boson Width In Pp̅ Collisions At √S = 1.8 Tev, T. Affolder, Kenneth A. Bloom, Collider Detector At Fermilab Collaboration

Kenneth Bloom Publications

This Letter describes a direct measurement of the W boson total decay width, Γ W, using the Collider Detector at Fermilab. The measurement uses an integrated luminosity of 90 pb-1, collected during the 1994–1995 run of the Fermilab Tevatron pp̅ collider. The width is determined by normalizing predicted signal and background distributions to 49 844 W candidates and 21 806 Wμν candidates in the transverse-mass region MT < 200 GeV and then fitting the predicted shape to the 438 electron events and 196 muon events in the high-MT region, 100<MT < 200 GeV. The result is G Γ W= 2.04 ± 0.11(stat) ± 0.09(syst) GeV.


Semi-Regular Mesh Extraction From Volumes, Z. J. Wood, M. Desbrun, P. Schroder, D. Breen Oct 2000

Semi-Regular Mesh Extraction From Volumes, Z. J. Wood, M. Desbrun, P. Schroder, D. Breen

Computer Science and Software Engineering

We present a novel method to extract iso-surfaces from distance volumes. It generates high quality semi-regular multiresolution meshes of arbitrary topology. Our technique proceeds in two stages. First, a very coarse mesh with guaranteed topology is extracted. Subsequently an iterative multi-scale force-based solver refines the initial mesh into a semi-regular mesh with geometrically adaptive sampling rate and good aspect ratio triangles. The coarse mesh extraction is performed using a new approach we call surface wavefront propagation. A set of discrete iso-distance ribbons are rapidly built and connected while respecting the topology of the iso-surface implied by the data. Subsequent multi-scale …


Measurement Of J/Ψ And Ψ(2s) Polarization In Pp̅ Collisions At √S = 1.8 Tev, T. Affolder, Kenneth A. Bloom, Collider Detector At Fermilab Collaboration Oct 2000

Measurement Of J/Ψ And Ψ(2s) Polarization In Pp̅ Collisions At √S = 1.8 Tev, T. Affolder, Kenneth A. Bloom, Collider Detector At Fermilab Collaboration

Kenneth Bloom Publications

We have measured the polarization of J/ψ and ψ(2S) mesons produced in pp̅ collisions at √s= 1.8 TeV, using data collected at the Collider Detector at Fermilab during 1992–1995. The polarization of promptly produced J/ψ[ψ(2S)] mesons is isolated from those produced in B-hadron decay, and measured over the kinematic range 4 [5.5] < PT < 20 GeV/c and |y| < 0.6. For PT≥ 12 GeV/c we do not observe significant polarization in the prompt component.


Basaltic Lava Domes, Lava Lakes, And Volcanic Segmentation On The Southern East Pacific Rise, Scott M. White, Ken C. Macdonald, Rachel M. Haymon Oct 2000

Basaltic Lava Domes, Lava Lakes, And Volcanic Segmentation On The Southern East Pacific Rise, Scott M. White, Ken C. Macdonald, Rachel M. Haymon

Faculty Publications

Meter-scale DSL-120 sonar mapping and coregistered Argo II photographic observations reveal changes in eruptive style that closely follow the third-order structural segmentation of the ridge axis on the southern East Pacific Rise, 17o11'-18o37'S. Near segment ends we observe abundant basaltic lava domes which average 20 rn in height and 200 rn in basal diameter and have pillow lava as the dominant lava morphology. The ubiquity of pillow lava suggests low effusion rate eruptions. The abundance of lava domes suggests that the fissure eruptions were of sufficient duration to focus and produce a line of volcanic edifices. …


Inhomogeneous Nucleation In A Quark-Hadron Pphase Transition, P. Shukla, A. K. Mohanty, S. K. Gupta, Marcelo Gleiser Oct 2000

Inhomogeneous Nucleation In A Quark-Hadron Pphase Transition, P. Shukla, A. K. Mohanty, S. K. Gupta, Marcelo Gleiser

Dartmouth Scholarship

The effect of subcritical hadron bubbles on a first-order quark-hadron phase transition is studied. These subcritical hadron bubbles are created due to thermal fluctuations, and can introduce a finite amount of phase mixing (quark phase mixed with hadron phase) even at and above the critical temperature. For reasonable choices of surface tension and correlation length, as obtained from the lattice QCD calculations, we show that the amount of phase mixing at the critical temperature remains below the percolation threshold. Thus, as the system cools below the critical temperature, the transition proceeds through the nucleation of critical-size hadron bubbles from a …


Lava And Ice Interaction At Stratovolcanoes: Use Of Characteristic Features To Determine Past Glacial Extents And Future Volcanic Hazards, David T. Lescinsky, Jonathan H. Fink Oct 2000

Lava And Ice Interaction At Stratovolcanoes: Use Of Characteristic Features To Determine Past Glacial Extents And Future Volcanic Hazards, David T. Lescinsky, Jonathan H. Fink

Geology Faculty Publications and Presentations

Structures resulting from lava and ice interaction are common at glaciated stratovolcanoes. During summit eruptions at stratovolcanoes, meltwater is produced and travels freely down steep slopes and thin permeable valley glaciers, eroding the ice and enlarging preexisting glacial drainages. As a result, in this environment have produced few catastrophic floods. Lava flowing into the open channels and voids in the glaciers becomes confined and grows thicker, filling the available space and producing steep-sided bodies with smooth, bulbous contact surfaces. Quenching of lava against ice or by water forms small-scale features such as tensional fractures and glass. As the amount of …


Nonadiabatic Heat-Capacity Measurements Using A Superconducting Quantum Interference Device Magnetometer, A.I. Kharkovski, Christian Binek, Wolfgang Kleeman Oct 2000

Nonadiabatic Heat-Capacity Measurements Using A Superconducting Quantum Interference Device Magnetometer, A.I. Kharkovski, Christian Binek, Wolfgang Kleeman

Christian Binek Publications

Nonadiabatic measurements of the heat capacity involving sample-inherent thermometry are proposed. The method is realized with superconducting quantum interference device magnetometry and applied to FeBr2 single crystals by using the magnetization for both thermometry and relaxation calorimetry. When heating with a step pulse of laser light, the magnetization relaxes on a characteristic time scale Ί = RC, where C is the heat capacity and R is the heat resistance between the sample and the bath. R is independently determined from the temperature dependence of the magnetic moment measured with and without stationary light irradiation. ©2000 American Institute of …

It has been a distinct pleasure for me to have attended and participated in each of the previous eight Eastern Wildlife Damage Management Conferences, dating back to 1983, as a member of the planning committees, as well as for this first Wildlife Damage Management Conference. I have enjoyed participating, learning from each conference, as well as visiting with old friends and colleagues and meeting new colleagues. Although I have been around long enough to know that no matter how hard you try you can't please everyone, I ask those of you who enjoyed participating in this Conference to join me …


Search For New Physics In Eμx Data At Dø Using Sleuth: A Quasi-Model-Independent Search Strategy For New Physics, B. Abbott, Gregory R. Snow, D0 Collaboration Oct 2000

Search For New Physics In Eμx Data At Dø Using Sleuth: A Quasi-Model-Independent Search Strategy For New Physics, B. Abbott, Gregory R. Snow, D0 Collaboration

Gregory Snow Publications

We present a quasi-model-independent search for the physics responsible for electroweak symmetry breaking. We define final states to be studied, and construct a rule that identifies a set of relevant variables for any particular final state. A new algorithm (“SLEUTH”) searches for regions of excess in those variables and quantifies the significance of any detected excess. After demonstrating the sensitivity of the method, we apply it to the semi-inclusive channel ℯμX collected in 108 pb-1 of pp̅ collisions at √s = 1.8 TeV at the DØ experiment during 1992–1996 at the Fermilab Tevatron. We find no evidence of …

History And Future Of Wildlife Damage Management Conference, Daniel J. Decker Oct 2000

History And Future Of Wildlife Damage Management Conference, Daniel J. Decker

Wildlife Damage Management Conference Proceedings

The Eastern Wildlife Damage Management (EWDM) Conference was developed (1st conference held in 1983) to focus on people-wildlife interaction issues occurring in the eastern U.S. Developed as a Renewable Resources Extension Act activity, the purpose of the conference was to improve wildlife resource management and increase outputs of agricultural and forestry commodities. A primary planning issue for the 1st EWDM Conference was whether to represent the conference focus as wildlife damage "control" or "management." Control was selected initially, but the title evolved since then to be replaced by "management," reflecting the central role of wildlife conflict mitigation in wildlife management. …

The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter Oct 2000

The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter

Wildlife Damage Management Conference Proceedings

Airports attract large numbers of wildlife primarily because they offer immense tracts of foraging and nesting habitats free from the threat of predation. Border collies can serve as an effective means of wildlife control in these environments by introducing a predator into the ecosystem. Many wildlife dispersal methods seek to imitate predators or the effect of predators and become increasingly ineffective as wildlife habituate to the stimuli. However, border collies are true predators, representing an actual, not perceived, threat to wildlife thereby eliminating the problems of habituation. Six airports and military bases have initiated use of border collies at their …


Comparison Of Standard And Modified Soft Catch® Traps For Capturing Coyotes, Bobcats, And Raccoons, Jan F. Kamler, Chad Richardson, Philip S. Gipson Oct 2000

Comparison Of Standard And Modified Soft Catch® Traps For Capturing Coyotes, Bobcats, And Raccoons, Jan F. Kamler, Chad Richardson, Philip S. Gipson

Wildlife Damage Management Conference Proceedings

Capture rates and injury rates of coyotes (Canis latrans), bobcats {Lynx rufus), and raccoons (Procyon lotor) captured in standard No. 3 Soft Catch® traps were compared to those captured in the same trap type modified with the Taos Lightening Spring™ (TLS) double torsion spring. All traps were equipped with Paws-I-Trip™ pan tension devices and were successful in excluding most small nontarget species. We captured 15 coyotes and 17 bobcats from October 1995 to March 1997. In addition, 23 raccoons, a large nontarget species, were captured. Capture rates for coyotes were higher (P < 0.10) in TLS modified traps (92%) than standard traps (27%), whereas capture rates were similar (P > 0.10) for raccoons (85% and 67%, respectively) and …


Aversive And Disruptive Stimulus Applications For Managing Predation, John A. Shivik, Daniel J. Martin Oct 2000

Aversive And Disruptive Stimulus Applications For Managing Predation, John A. Shivik, Daniel J. Martin

Wildlife Damage Management Conference Proceedings

The range expansion and reintroduction of mammalian predators (e.g., wolves, coyotes and bears) coupled with growing disfavor for traditional tools of wildlife management creates an immediate need for alternative, non-lethal, but effective techniques for managing predation on livestock. Scientists at the National Wildlife Research Center are using advanced technology and animal behavior concepts (e.g., aversive and disruptive stimuli) to develop new tools for the prevention of damage by large mammalian predators, and this paper is a review of our pilot studies investigating these techniques. Recently tested tools include behavior contingent disruptive stimulus devices for wolves and coyotes. Experiments indicate the …


Survey Of Factors Affecting The Success Of Clemson Beaver Pond Levelers Installed In Mississippi By Wildlife Services, Dale L. Nolte, Seth R. Swafford, Charles A. Sloan Oct 2000

Survey Of Factors Affecting The Success Of Clemson Beaver Pond Levelers Installed In Mississippi By Wildlife Services, Dale L. Nolte, Seth R. Swafford, Charles A. Sloan

Wildlife Damage Management Conference Proceedings

Clemson beaver pond levelers were developed as a tool to enable land managers to manipulate water flow past beaver (Castor canadensis) dams. Wildlife Services has installed several of these devices in collaboration with landowners. We conducted a survey to determine if we could identify factors that impacted whether the devices were meeting landowner objectives. Fifty percent of the 40 levelers surveyed were still operating and regarded as successful. Factors considered in the survey included management objectives, time since the leveler was installed, watershed characteristics, physical attributes of the stream and of the beaver dam where the leveler was installed, and …

Gis Use In Oral Rabies Vaccine Programs, Patricia R. Bright, Elizabeth Schmidt, Francois Elvinger, Michelle M. Weisbarth, R. F. Bulley, Cynthia L. Mills

Wildlife Damage Management Conference Proceedings

Frequent human and domestic animal exposures to rabid wildlife have raised the public's awareness, leading to an increase in the number of wildlife submissions for rabies testing as well as an increase in the number of people requiring post exposure prophylaxis treatment. During 1998 and 1999, the Health and Human Services Department of a densely populated urban/suburban county in Virginia received a total of 955 animal submissions for rabies testing. Wildlife accounted for 714 of the submissions. Seventy-nine of the submitted wildlife were found dead, 445 were killed or euthanized for testing (190 unknown). Of the wildlife submissions, 152 (21%) …


Community Bat Management, Jerry D. Hassinger, Calvin M. Butchkoski, Harold S. Korber Oct 2000

Community Bat Management, Jerry D. Hassinger, Calvin M. Butchkoski, Harold S. Korber

Wildlife Damage Management Conference Proceedings

When a house bat colony (primarily Myotis lucifugus) is excluded from a traditional maternity roost, surviving bats add to nearby roosts or access new roosts in other buildings. To prevent this and the potential for attendant nuisance, and to conserve bats, the Pennsylvania Game Commission recommends using one or more bat boxes to attract the displaced colony. The "standard-sized" bat box used in Pennsylvania will house up to 250 little brown bats. This reactive technique has proved useful for managing single, small colonies (< 1,000 bats) in rural areas. We are, however, trying a different, proactive technique to manage large colonies or multiple colonies in a community. Newport, PA, for example, has multiple colonies in buildings within 200 meters of riparian habitat along the Juniata River. Over 7,000 bats were counted exiting a single building. To begin the process of managing these bats, the high school conservation club and town leaders were engaged and presented information about the value of bats. Programs were also presented to a school assembly and to the community. As a result, the conservation club was provided with a site at the community's water treatment plant to erect a bat condo. This site is within 1 km of at least 2 large bat colonies in old buildings. The condo is a 2.4 m square box on posts. It's 2.4 m tall with its bottom 3 m above the ground. Inside, 80 sheets of plywood provide roosting crevices for at least 2,500 bats. Supervised by the Wildlife Diversity Section of the Game Commission, the condo was built in late spring, 1999. A chain-link fence helps protect it from vandalism.


Comprehensive Management Of Commensal Bats, Stephen C. Frantz, Brian R. Laniewicz Oct 2000

Comprehensive Management Of Commensal Bats, Stephen C. Frantz, Brian R. Laniewicz

Wildlife Damage Management Conference Proceedings

This paper reviews the basic concepts behind a comprehensive management approach to managing commensal species, and then considers how this approach is applied to bats that live within and about the built environment. Management activities should take into consideration the whole environment in which the target species is active, including the periodic changes that occur within that environment. Comprehensive management includes a clear understanding of: the biology, behavior and ecology of the species to be managed; the environment in which that species is active (especially harborage location); and the appropriate intervention methods used to manage such species. Interventions fall under …


Wildlife Damage In The Suburbs: Conflicts In A Human-Wildlife Landscape, Rebecca Field Oct 2000

Wildlife Damage In The Suburbs: Conflicts In A Human-Wildlife Landscape, Rebecca Field

Wildlife Damage Management Conference Proceedings

The sprawling communities surrounding cities pose a paradox for wildlife. Suburban habitat, with parks, greenways, and planned open spaces, provide attractive habitat with abundant resources for some wildlife species. Yet the landscape is dominated by human activities and disturbances. Species with little tolerance for human disturbance and habitat changes have difficulty maintaining their populations in suburban environments. Yet more adaptable species flourish in suburban areas where there are less predators, increased food resources, and abundant habitat for cover and raising young. The resulting overabundant wildlife populations pose increasing problems for biologists, wildlife damage practitioners, and the public. Management of urban …


Efforts To Enhance Stakeholder Communications In North Carolina's Wildlife Damage Control Agent System, Peter T. Bromley, Carl W. Betsill Oct 2000

Efforts To Enhance Stakeholder Communications In North Carolina's Wildlife Damage Control Agent System, Peter T. Bromley, Carl W. Betsill

Wildlife Damage Management Conference Proceedings

In 1995, North Carolina Wildlife Resources Commission (NCWRC) established policy and rules for handling of nuisance wildlife by Wildlife Damage Control Agents (WDCA). The policy required a one-day long training session, culminating in an open book, certification examination. The North Carolina Cooperative Extension Service (NCCES) conducted the training and administered the examination. The certification-training program covered principles of wildlife damage management, wildlife laws and regulations, humane handling of animals and euthanasia, human health risks from exposure to wildlife, professional ethics, and sources of technical information. Between Octoberl995 and March 2000,7 certification-training sessions were held and 289 WDCA's were certified, with …


Perceptions Of White-Tailed Deer Abundance And Management Among Hunters And Landowners In Illinois, Craig A. Miller, Paul Shelton Oct 2000

Perceptions Of White-Tailed Deer Abundance And Management Among Hunters And Landowners In Illinois, Craig A. Miller, Paul Shelton

Wildlife Damage Management Conference Proceedings

State wildlife agencies often find themselves between hunters and landowners in managing white-tailed deer. During 1999 the Illinois Department of Natural Resources (IDNR) restricted archery deer harvest in a 5-county region of East-central Illinois to antlered deer only during the first month of the season. Restrictions were due to declining deer populations and increased archery harvest in the 5-county zone. Hunters in adjacent Shelby County claimed they were seeing fewer deer and lobbied both the IDNR and state legislators for inclusion in the restricted zone during the fall 2000 hunting season. We conducted a telephone survey of resident archery deer …


Den Site Selection And Movement Patterns Of Female Raccoons Following Removal And Exclusion From Residences, Anthony J. Denicola, Michael A. O'Donnell Oct 2000

Den Site Selection And Movement Patterns Of Female Raccoons Following Removal And Exclusion From Residences, Anthony J. Denicola, Michael A. O'Donnell

Wildlife Damage Management Conference Proceedings

Raccoons (Procyon lotor) are one of many wildlife species that have adapted to survive in urban/suburban environments. Classified as a rabies vector species in many eastern states, their disposition after being handled by wildlife specialists is often dictated by this human health concern. Specifically, some states prohibit relocation and mandate that raccoons be released on site or euthanized. Although management using nonlethal means is often preferred by some segments of the human population, several questions remain to be addressed before appropriate agency policies regarding the handling of urban wildlife can be determined. There is little information available regarding the fate …


Special Resident Canada Goose Hunting Seasons In Pennsylvania - Management Implications For Controlling Resident Canada Geese, John P. Dunn, Kevin J. Jacobs Oct 2000

Special Resident Canada Goose Hunting Seasons In Pennsylvania - Management Implications For Controlling Resident Canada Geese, John P. Dunn, Kevin J. Jacobs

Wildlife Damage Management Conference Proceedings

Special hunting seasons were first implemented in 1992 to help reduce the growth rate of Pennsylvania's rapidly expanding resident Canada goose (Branta canadensis) population. Special seasons timed to occur before and after fall migration were successful in harvesting resident and not migrant Canada geese. Since 1992, September and late season hunting opportunities have been gradually expanded to include the entire state. The special season harvest of resident Canada geese has increased from about 13,000 birds in 1992 to over 68,000 in 1999. Special hunting seasons now account for over 80% of the entire Canada goose kill in Pennsylvania. Despite the …


Investigations Of Methods To Reduce Damage By Voles, Gary W. Witmer, A. A. Hakim, Brian W. Moser Oct 2000

Investigations Of Methods To Reduce Damage By Voles, Gary W. Witmer, A. A. Hakim, Brian W. Moser

Wildlife Damage Management Conference Proceedings

Voles (Microtus spp.), small burrowing rodents, range over much of North America. Populations cycle and achieve peak densities every 3-5 years. This can result in severe damage to various resources: orchards, forest plantings, alfalfa and other crops, ornamentals, lawns, and gardens. A variety of methods are used to reduce vole damage, but there is still a need for new, cost-effective, and environmentally benign approaches. We investigated numerous candidate repellents and barriers with indoor vole colonies in soil-filled tanks. Several compounds (blood meal, capsaicin, castor oil, coyote urine, quebracho, and thiram) showed promise as repellents, but only at high concentrations. Many …


Porcine Zona Pellucida Vaccine (Zonacon) As An Immunocontraceptive In Deer, Lowell A. Miller, Gary J. Killian, Paul D. Curtis Oct 2000

Porcine Zona Pellucida Vaccine (Zonacon) As An Immunocontraceptive In Deer, Lowell A. Miller, Gary J. Killian, Paul D. Curtis

Wildlife Damage Management Conference Proceedings

Abstract: Research on a PZP contraceptive vaccine was performed at 2 sites; Penn State University and Seneca Army Depot in upper New York. The Penn State study included immune response, hormone analysis, fawning and behavioral analysis. The Seneca depot studied behavioral and fawning response in a semi-free ranging setting. At Penn State University, in a 7 year study, does were actively immunized for two years resulting in a 90% reduction in fawns. They were followed for 5 more years to determine if the effect was reversible. The reduction in fawning over the 7 years was 72%. Most deer returned to …
