The Creation And Evaluation Of Novel Canine Training Aids For Cocaine Using Molecularly Encapsulated Sol-Gel Polymers And An Investigation Of Canine Field Accuracy, Michelle Cerreta

FIU Electronic Theses and Dissertations

Biological detectors, such as canines, are valuable tools used for the rapid identification of illicit materials. However, recent increased scrutiny over the reliability, field accuracy, and the capabilities of each detection canine is currently being evaluated in the legal system. For example, the Supreme Court case, State of Florida v. Harris, discussed the need for continuous monitoring of canine abilities, thresholds, and search capabilities. As a result, the fallibility of canines for detection was brought to light, as well as a need for further research and understanding of canine detection. This study is two-fold, as it looks to not only …

Moor Movement: Automated Docking On Drought-Stricken Reservoirs, Daniel Beck

Landscape Architecture

Moor Movement establishes a mechanized docking system for unpredictable shoreline fluctuations on inland lakes and reservoirs. Due to climate change and warmer global temperatures, the threat of ocean level rise has initiated massive proposals to address the interface between ocean and man-made infrastructure. While this is a monumental problem, ocean level rise is not the only immediate threat. The recently declared emergency drought conditions in California are finally bringing attention to inland lakes and reservoirs. While ocean levels might rise 2-7 feet in 100 years, a lake could drop 100 feet in 5 years. What happens to access roads, marinas, …

Split-Beam Echosounder Observations Of Natural Methane Seep Variability In The Northern Gulf Of Mexico, Kevin W. Jerram, Thomas C. Weber, Jonathan Beaudoin

Center for Coastal and Ocean Mapping

A method for positioning and characterizing plumes of bubbles from marine gas seeps using an 18 kHz scientific split-beam echo sounder (SBES) was developed and applied to acoustic observations of plumes of presumed methane gas bubbles originating at approximately 1400 m depth in the northern Gulf of Mexico. A total of 161 plume observations from 27 repeat surveys were grouped by proximity into 35 clusters of gas vent positions on the seafloor. Profiles of acoustic target strength per vertical meter of plume height were calculated with compensation for both the SBES beam pattern and the geometry of plume ensonification. These …

Locating Gravitational Waves With Bayeswave, Belinda Cheeseboro, Tiffany Summerscales

Posters, Presentations, and Papers

LIGO is the Laser Interferometer Gravitational Wave Observatory. Its mission is to detect gravitational waves that could be caused by the interaction of massive gravitating bodies such as coalescing black holes, inspiraling neutron stars, etc. BayesWave is an algorithm that can analyze possible gravitational wave event data and determine the properties of candidate events such as sky location. This algorithm uses a combination of Bayesian probability theory and the Reverse Jump Markov chain Monte Carlo (RJMcMC) method to accomplish this goal. BayesWave is able to simultaneously model the gravitational wave signal the noise by using multi-component models. It uses the …

A Community Guide To Starting & Running A Wood Bank, Sabrina Vivian, Jessica Leahy

Forest Resources Student Scholarship

Imagine your local food pantry. Replace the food with firewood and you have programs known as wood banks. Like a food pantry, wood banks are programs that aim to help community members with life essentials by supplying firewood at little to no cost to those in need that rely on firewood as a heating source. As straightforward and tangible as these centers sound, as of 2014 only about a dozen wood banks are clearly recognized across the states of Maine, New Hampshire and Vermont, with only a handful consistently active in Maine. There may be many more wood banks that …

Sandpiles, Spanning Trees, And Plane Duality, Melody Chan, Darren B. Glass, Matthew Macauley, David Perkinson, Caryn Werner, Qiaoyu Yang

Math Faculty Publications

Let G be a connected, loopless multigraph. The sandpile group of G is a finite abelian group associated to G whose order is equal to the number of spanning trees in G. Holroyd et al. used a dynamical process on graphs called rotor-routing to define a simply transitive action of the sandpile group of G on its set of spanning trees. Their definition depends on two pieces of auxiliary data: a choice of a ribbon graph structure on G, and a choice of a root vertex. Chan, Church, and Grochow showed that if G is a planar ribbon graph, it …

Plant Community Composition And Structure Monitoring For Agate Fossil Beds National Monument, 2014 Annual Report, Michael Prowatzke, Stephen K. Wilson

United States National Park Service: Publications

Abstract

This report presents the results of vegetation monitoring efforts in 2014 at Agate Fossil Beds National Monument (AGFO) by the Northern Great Plains Inventory and Monitoring Network (NGPN).

During the fourth full year of field work, crew members from NGPN visited six plant community monitoring plots to collect data on the vegetation at AGFO. This is part of a long-term monitoring effort that will sample six of 15 randomly located upland plots every year, so that each plot is visited for two consecutive years and then rested for three years, on a five-year rotating basis. NGPN staff captured data …

Charged-To-Neutral Correlation At Forward Rapidity In Au + Au Collisions At √SNn=200 Gev, J. Kevin Adkins, Renee Fatemi, Suvarna Ramachandran, L. Adamczyk, G. Agakishiev, M. M. Aggarwal, Z. Ahammed, I. Alekseev, J. Alford, C. D. Anson, A. Aparin, D. Arkhipkin

Physics and Astronomy Faculty Publications

Event-by-event fluctuations of the multiplicities of inclusive charged particles and photons at forward rapidity in Au+Au collisions at √^S_NN=200 GeV have been studied. The dominant contribution to such fluctuations is expected to come from correlated production of charged and neutral pions. We search for evidence of dynamical fluctuations of different physical origins. Observables constructed out of moments of multiplicities are used as measures of fluctuations. Mixed events and model calculations are used as base lines. Results are compared to the dynamical net-charge fluctuations measured in the same acceptance. A nonzero statistically significant signal of dynamical fluctuations is …

The Symbiotic Relationship Between Information Retrieval And Informetrics, Dietmar Wolfram

School of Information Studies Faculty Articles

Informetrics and information retrieval (IR) represent fundamental areas of study within information science. Historically, researchers have not fully capitalized on the potential research synergies that exist between these two areas. Data sources used in traditional informetrics studies have their analogues in IR, with similar types of empirical regularities found in IR system content and use. Methods for data collection and analysis used in informetrics can help to inform IR system development and evaluation. Areas of application have included automatic indexing, index term weighting and understanding user query and session patterns through the quantitative analysis of user transaction logs. Similarly, developments …

A Catch Per Unit Effort (Cpue) Spatial Metric With Respect To The Western North Atlantic Pelagic Longline Fishery, Max Appelman

HCNSO Student Theses and Dissertations

Catch per unit effort (CPUE) is a quantitative method used to describe fisheries worldwide. CPUE can be presented as number of fish per 1000 hooks, number of fish per amount of fishing time, or with any unit of effort that best describes the fishery (e.g., search time, hooks per hour, number of trawls). CPUE is commonly used as an index to estimate relative abundance for a population. These indices are then applied within stock assessments so that fisheries managers can make justified decisions for how to manage a particular stock or fishery using options such as quotas, catch …

Nebraska’S Natural Resources Districts: An Assessment Of A Large-Scale Locally Controlled Water Governance Framework, Ann Bleed, Christina Hoffman Babbitt

Daugherty Water for Food Global Institute: Faculty Publications

In 1972 the State of Nebraska created the Natural Resources Districts (NRDs) to consolidate a multitude of single-purpose local natural resource districts into a more comprehensive, holistic, and efficient natural resources governance system. While consolidation and efficiency was important, so was the concept of maintaining local control. Thus, Nebraska rejected the governance framework of a single top-down state agency, preferring to create NRDs that are each governed by a locally elected board. The locally elected governing boards of the NRDs were given broad authorities over many of the state’s natural resources, including groundwater. Such a governance structure was, and to …

Rapid Phase Transformation Under Local Non-Equilibrium Diffusion Conditions, Sergey Sobolev

Sergey Sobolev

Phase transformation with a moving interface occurs under far from local equilibrium conditions when the interface moves with sufficiently high velocity. This deviation cannot be adequately described by the classical irreversible thermodynamics with diffusion equation of parabolic type because it assumes local equilibrium hypothesis. The local non-equilibrium diffusion model has been developed to take into account the deviation from local equilibrium during binary alloy solidification using the hyperbolic diffusion equation. The model introduces a finite propagation velocity of concentration disturbances in the bulk liquid VD as the characteristic diffusion parameter and predicts a sharp transition from diffusion controlled to diffusionless …
