Education for a Global Future: 21st Century Challenges in Sustainability & Climate Change Education

MORNING CONCURRENT TRACK 2: CREATION AND CORRECTION OF MYTHS ABOUT GLOBAL WARMING Moderator Robert Futrell Student Union Room 211 Matthew Lachniet – Global Warming Misconceptions and Myths: Barriers and Opportunities for Communicating Climate Change Science to a Non-scientific Audience Abstract: Opinions on an anthropogenic influence in global warming abound. Within the non-scientific public, the strength of one’s opinion commonly seems to be in inverse proportion to their knowledge of climate science. One reason for this disconnect between reality and opinion is the persistence of many climate change myths in popular knowledge of global warming. These myths are regularly propagated in …

Excited states in ²⁵⁶Rf were populated via the ²⁰⁸Pb(⁵⁰Ti,2n) fusion–evaporation reaction. Delayed γ-ray and electron decay spectroscopy was performed and three isomeric states in ²⁵⁶Rf have been identified. A fourth low-energy nonyrast state was identified from the γ-ray decay of one of the higher lying isomers. The states are interpreted as multi-quasiparticle excitations.

New Precision Orbits Of Bright Double-Lined Spectroscopic Binaries. Iii. Hd 82191, Ω Draconis, And 108 Herculis, Francis C. Fekel, Jocelyn Tomkin, Michael H. Williamson

Information Systems and Engineering Management Research Publications

We have determined improved spectroscopic orbits for three double-lined binaries, HD 82191 (Am), ω Dra (F5 V), and 108 Her (Am), using radial velocities from the 2.1 m telescope at McDonald Observatory, the coudé feed telescope at Kitt Peak National Observatory, and 2 m telescope at Fairborn Observatory. The orbital periods range from 5.28 to 9.01 days, and all three systems have circular orbits. The new orbital dimensions (a1 sin i and a2 sin i) and minimum masses (m1 sin3 i and m2 sin3 i) have accuracies of 0.2% or better. Our improved results confirm the large minimum masses of …

Evidence For The Decay BS0 → DS(*)DS(*) And A Measurement Of ΔγSCp/ΓS, V. M. Abazov, Kenneth A. Bloom, Gregory Snow, D0 Collaboration

Kenneth Bloom Publications

We search for the semi-inclusive process B_s⁰ → D_s^(*)D_s^(*) using 2.8 fb^-1 of pp collisions at √s = 1.96 TeV recorded by the D0 detector operating at the Fermilab Tevatron Collider.We observe 26.6 ± 8.4 signal events with a significance above background of 3.2 standard deviations yielding a branching ratio of B(b_s⁰ → D_s^(*)D_s^(*) = 0.035 ± 0.010(stat.) ± 0.011 (syst.). Under certain theoretical assumptions, these double-charm final states saturate CP-even eigenstates in the B_s⁰ decays resulting in a width …

Search For Anomalous Top-Quark Couplings With The D0 Detector, V. M. Abazov, Kenneth A. Bloom, Gregory Snow, D0 Collaboration

Kenneth Bloom Publications

Anomalous Wtb couplings modify the angular correlations of the top-quark decay products and change the single top-quark production cross section. We present limits on anomalous top-quark couplings by combining information from W boson helicity measurements in top-quark decays and anomalous coupling searches in the single top-quark final state. We set limits on right-handed vector couplings as well as left-handed and right-handed tensor couplings based on about 1 fb^-1 of data collected by the D0 experiment.

Measurement Of The Lifetime Of The BC± Meson In The Semileptonic Decay Channel, V. M. Abazov, Kenneth A. Bloom, Gregory Snow, D0 Collaboration

Kenneth Bloom Publications

Using approximately 1.3 fb^-1 of data collected by the D0 detector between 2002 and 2006, we measure the lifetime of the B_c^± meson in the B_c^± → J/ψμ^± + X final state. A simultaneous unbinned likelihood fit to the J/ψ + μ invariant mass and lifetime distributions yields a signal of 881 ± 80(stat) candidates and a lifetime measurement of τ(B_c^±) = 0.448_-0.036^+0.038(stat) ± 0.032(syst) ps.

A Hybrid Templated-Based Composite Classification System, Michael A. Turnbaugh

Theses and Dissertations

An automatic target classification system contains a classifier which reads a feature as an input and outputs a class label. Typically, the feature is a vector of real numbers. Other features can be non-numeric, such as a string of symbols or alphabets. One method of improving the performance of an automatic classification system is through combining two or more independent classifiers that are complementary in nature. Complementary classifiers are observed by finding an optimal method for partitioning the problem space. For example, the individual classifiers may operate to identify specific objects. Another method may be to use classifiers that operate …

Mercury Characterization In Soil Collected Nearby The Department Of Energy Oak Ridge Reservation, Julio Cesar Cabrera

FIU Electronic Theses and Dissertations

Total mercury (Hg) concentration provides insufficient information to understand Hg behavior in Hg-contaminated soil systems and to seek potential remediation technologies, because the distribution, mobility, bioavailability, and toxicity of Hg are dependent on Hg forms present in soils. The phase association of Hg in soil is investigated to evaluate potential environmental risk through combination of total Hg determination, soil fractionation, and speciation analysis of Hg in a Hg-contaminated DOE site. Besides total Hg concentration analysis, sequential extraction procedures and thermal desorption techniques were employed to study Hg binding forms in soils in this study. Total mercury concentrations ranging from less …

Observing The Evolution Of The Universe, Scott Watson

Physics - All Scholarship

How did the universe evolve? The fine angular scale (l>1000) temperature and polarization anisotropies in the CMB are a Rosetta stone for understanding the evolution of the universe. Through detailed measurements one may address everything from the physics of the birth of the universe to the history of star formation and the process by which galaxies formed. One may in addition track the evolution of the dark energy and discover the net neutrino mass. We are at the dawn of a new era in which hundreds of square degrees of sky can be mapped with arcminute resolution and sensitivities …

Transitional Probabilities For The Four-State Random Walk On A Lattice In The Presence Of Partially Reflecting Boundaries, Ramakrishna Janaswamy

Ramakrishna Janaswamy

The four-state random walk (4RW) model, wherein the particle is endowed with two states of spin and two states of directional motion in each space coordinate, permits a stochastic solution of the Schrödinger equation (or the equivalent parabolic equation) without resorting to the usual analytical continuation in complex space of the particle trajectories. Analytical expressions are derived here for the various transitional probabilities in a 4RW by employing generating functions and eigenfunction expansions when the particle moves on a 1+1 space-time lattice with two-point boundary conditions. The most general case of dissimilar boundaries with partially reflecting boundary conditions is treated …

Numerical Analysis For Relevant Features In Intrusion Detection (Narfid), Jose Andres Gonzalez

Theses and Dissertations

Identification of cyber attacks and network services is a robust field of study in the machine learning community. Less effort has been focused on understanding the domain space of real network data in identifying important features for cyber attack and network service classification. Motivations for such work allow for anomaly detection systems with less requirements on data “sniffed” off the network, extraction of features from the traffic, reduced learning time of algorithms, and ideally increased classification performance of anomalous behavior. This thesis evaluates the usefulness of a good feature subset for the general classification task of identifying cyber attacks and …

Using Predictive Rendering As A Vision-Aided Technique For Autonomous Aerial Refueling, Adam D. Weaver

Theses and Dissertations

This research effort seeks to characterize a vision-aided approach for an Unmanned Aerial System (UAS) to autonomously determine relative position to another aircraft in a formation, specifically to address the autonomous aerial refueling problem. A system consisting of a monocular digital camera coupled with inertial sensors onboard the UAS is analyzed for feasibility of using this vision-aided approach. A three-dimensional rendering of the tanker aircraft is used to generate predicted images of the tanker as seen by the receiver aircraft. A rigorous error model is developed to model the relative dynamics between an INS-equipped receiver and the tanker aircraft. A …

Laboratory Studies Of Ice Formation Pathways From Ammonium Sulfate Particles, M. E. Wise, K. J. Baustian, M. A. Tolbert

CUP Faculty Research

Cirrus clouds are composed of ice particles and their formation pathways have been studied extensively in the laboratory. The ability of ammonium sulfate particles to act as nuclei for cirrus clouds has been of particular importance because of their ubiquitous presence in the upper troposphere. The results of past laboratory experiments of homogeneous ice nucleation from ammonium sulfate particles show a wide range of freezing conditions. In the present study, a flow tube apparatus equipped with Fourier transform infrared spectroscopy was used to reexamine these discrepancies. It was found that when ammonium sulfate particles were preconditioned at 100% relative humidity …

Characterizing The Statistical Properties And Global Distribution Of Dansgaard-Oeschger Events, Andrea Michelle Thomas

Theses and Dissertations

Ice core records from Greenland have shown times of rapid warming during the most recent glacial period, called Dansgaard-Oeschger (D-O) events. D-O events are important to our understanding of both past climate systems and modern climate volatility. In this paper, we present new approaches for statistically evaluating the existence of cyclicity in D-O events and the possible lagged correlation between the Greenland and Antarctica temperature records. Specifically, we consider permutation testing and bootstrapping methodologies for assessing the cyclicity of D-O events and the correlation between the Greenland and Antarctica records. We find that there is not enough evidence to conclude …

A Simulated Annealing Approach To Communication Network Design, Stephen J. Sugden, Marcus Randall, Graham Mcmahon

Stephen Sugden

This paper explores the use of the meta-heuristic search algorithm Simulated Annealing for solving a minimum cost network synthesis problem. This problem is a common one in the design of telecommunication networks. The formulation we use models a number of practical problems with hop-limit, degree and capacity constraints. Emphasis is placed on a new approach that uses a knapsack polytope to select amongst a number of pre-computed traffic routes in order to synthesise the network. The advantage of this approach is that a subset of the best routes can be used instead of the whole set, thereby making the process …

The Online Privacy Frontier, Katina Michael

Professor Katina Michael

Many web sites pride themselves on offering personalised customer service, but that really depends on the amount of information the online shopper is willing to give the online merchant. In most cases, unless a purchase is made or some other form of transaction is enacted, the online shopper will not declare their identity. How personalised can an experience be online if one entity decides to remain anonymous? The online merchant has little, if any, information to go on apart from perhaps a cookie that tells them that the visitor is a repeat visitor to that web site. The seller does …
