A Speculative Approach To Parallelization In Particle Swarm Optimization, Matthew Gardner, Andrew Mcnabb, Kevin Seppi

Faculty Publications

Particle swarm optimization (PSO) has previously been parallelized primarily by distributing the computation corresponding to particles across multiple processors. In these approaches, the only benefit of additional processors is an increased swarm size. However, in many cases this is not efficient when scaled to very large swarm sizes (on very large clusters). Current methods cannot answer well the question: “How can 1000 processors be fully utilized when 50 or 100 particles is the most efficient swarm size?” In this paper we attempt to answer that question with a speculative approach to the parallelization of PSO that we refer to as …

We present the results of 16 Swift-triggered Gamma-ray burst (GRB) follow-up observations taken with the Very Energetic Radiation Imaging Telescope Array System (VERITAS) telescope array from 2007 January to 2009 June. The median energy threshold and response time of these observations were 260 GeV and 320 s, respectively. Observations had an average duration of 90 minutes. Each burst is analyzed independently in two modes: over the whole duration of the observations and again over a shorter timescale determined by the maximum VERITAS sensitivity to a burst with a t^−1.5 time profile. This temporal model is characteristic of GRB …

Characterizing The Sediment Provenance Of East Antarctica's Weak Underbelly: The Aurora And Wilkes Sub-Glacial Basins, Elizabeth L. Pierce, Trevor Williams, Tina Van De Flierdt, Sidney R. Hemming, Steven L. Goldstein, Stefanie A. Brachfeld

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

[1] The Wilkes and Aurora basins are large, low-lying sub-glacial basins that may cause areas of weakness in the overlying East Antarctic ice sheet. Previous work based on ice-rafted debris (IRD) provenance analyses found evidence for massive iceberg discharges from these areas during the late Miocene and Pliocene. Here we characterize the sediments shed from the inferred areas of weakness along this margin (94°E to 165°E) by measuring40Ar/39Ar ages of 292 individual detrital hornblende grains from eight marine sediment core locations off East Antarctica and Nd isotopic compositions of the bulk fine fraction from the same sediments. We further expand …

In 2007, R Coronae Borealis (RCrB) went into a historically deep and long decline. In this state, the dust acts like a natural coronagraph at visible wavelengths, allowing faint nebulosity around the star to be seen. Imaging has been obtained from 0.5 to 500 μm with Gemini/GMOS, Hubble Space Telescope/WFPC2, Spitzer/MIPS, and Herschel/SPIRE. Several of the structures around RCrB are cometary globules caused by wind from the star streaming past dense blobs. The estimated dust mass of the knots is consistent with their being responsible for the RCrB declines if they form along the line of sight to the star. …

Elliptic Operators And Maximal Regularity On Periodic Little-Hölder Spaces, Jeremy Lecrone

Department of Math & Statistics Faculty Publications

We consider one-dimensional inhomogeneous parabolic equations with higher-order elliptic differential operators subject to periodic boundary conditions. In our main result we show that the property of continuous maximal regularity is satisfied in the setting of periodic little-Hölder spaces, provided the coefficients of the differential operator satisfy minimal regularity assumptions.We address parameter-dependent elliptic equations, deriving invertibility and resolvent bounds which lead to results on generation of analytic semigroups. We also demonstrate that the techniques and results of the paper hold for elliptic differential operators with operator-valued coefficients, in the setting of vector-valued functions.

The Acs Survey Of Galactic Globular Clusters. Xi. The Three-Dimensional Orientation Of The Sagittarius Dwarf Spheroidal Galaxy And Its Globular Clusters, Michael H. H. Siegel, Steven R. Majewski, David R. Law, Ata Sarajedini, Aaron Dotter, A Marín-Franch, Brian Chaboyer

Dartmouth Scholarship

We use observations from the Hubble Space Telescope Advanced Camera for Surveys (HST/ACS) study of Galactic globular clusters to investigate the spatial distribution of the inner regions of the disrupting Sagittarius dwarf spheroidal galaxy (Sgr). We combine previously published analyses of four Sgr member clusters located near or in the Sgr core (M54, Arp 2, Terzan 7, and Terzan 8) with a new analysis of diffuse Sgr material identified in the background of five low-latitude Galactic bulge clusters (NGC 6624, 6637, 6652, 6681, and 6809) observed as part of the ACS survey. By comparing the bulge cluster color-magnitude …

Race/Ethnicity, Gender, Weight Status, And Colorectal Cancer Screening., Heather Bittner Fagan, Ronald E Myers, Constantine Daskalakis, Randa Sifri, Arch G Mainous, Richard Wender

Department of Medical Oncology Faculty Papers

Background. The literature on colorectal cancer (CRC) screening is contradictory regarding the impact of weight status on CRC screening. This study was intended to determine if CRC screening rates among 2005 National Health Interview Survey (NHIS) respondent racial/ethnic and gender subgroups were influenced by weight status. Methods. Univariable and multivariable logistic regression analyses were performed to determine if CRC screening use differed significantly among obese, overweight, and normal-weight individuals in race/ethnic and gender subgroups. Results. Multivariable analyses showed that CRC screening rates did not differ significantly for individuals within these subgroups who were obese or overweight as compared to their …

Assessment Of The Socrative Platform As An Interactive And Didactic Tool In The Performance Improvement Of Stem University Students, Roberto Gómez-Espina, Delia Rodríguez-Oroz, Manuel Chávez, Cristian Saavedra, María Jesús Bravo

Higher Learning Research Communications

This paper collects and analyzes students' academic results related to the change in teaching methodologies used in different subjects of different science and engineering university courses between 2013 and 2016. This change means introducing active methodologies such as gamification and ICT instead of a traditional methodology. With this purpose the use of Socrative, a platform that has been designed for the educational field, was introduced during said period. Interaction with the Socrative platform took place in well prepared classrooms with computers and internet connections, including the use of personal mobile devices (laptops, smartphones and tablets) according to the BYOD methodology. …

Modeling Criminal Careers As Departures From A Unimodal Population Age-Crime Curve: The Case Of Marijuana Use, Donatello Telesca, Elena Erosheva, Derek Kreager, Ross Matsueda

COBRA Preprint Series

A major aim of longitudinal analyses of life course data is to describe the within- and between-individual variability in a behavioral outcome, such as crime. Statistical analyses of such data typically draw on mixture and mixed-effects growth models. In this work, we present a functional analytic point of view and develop an alternative method that models individual crime trajectories as departures from a population age-crime curve. Drawing on empirical and theoretical claims in criminology, we assume a unimodal population age-crime curve and allow individual expected crime trajectories to differ by their levels of offending and patterns of temporal misalignment. We …

Toxicity Profiling Of Engineered Nanomaterials Via Multivariate Dose Response Surface Modeling, Trina Patel, Donatello Telesca, Saji George, Andre Nel

COBRA Preprint Series

New generation in-vitro high throughput screening (HTS) assays for the assessment of engineered nanomaterials provide an opportunity to learn how these particles interact at the cellular level, particularly in relation to injury pathways. These types of assays are often characterized by small sample sizes, high measurement error and high dimensionality as multiple cytotoxicity outcomes are measured across an array of doses and durations of exposure. In this article we propose a probability model for toxicity profiling of engineered nanomaterials. A hierarchical framework is used to account for the multivariate nature of the data by modeling dependence between outcomes and thereby …

American Environmentalism And The City: An Ecosystem Services Perspective, Dorothy C. Ibes

Cities and the Environment (CATE)

This study traces the evolution of eight influential American environmental organizations and their relationship with, and conceptualizations of, ‘the city’ and ‘nature.’ Guided by the ecosystem services framework, the organizations’ urban-based initiatives were analyzed to determine what types of ecosystem services they emphasized and what the implications are for cities and environmental health. Results from historical, content, and interview analyses reveal the potential of the ecosystem services framework to unite the interests and efforts of multiple stakeholders, including urbanists, ecologists, economists, and environmentalists in a way that enhances both urban quality of life and conservation efforts overall.

Meteoric Diagenesis Of Plio-Pleistocene Reef Terraces In The Southern Dominican Republic, Yulaika Hernawati

Open Access Theses

Four prograding reef terraces (6, 15, 30, and 50 m) have been repetitively exposed to marine and freshwater alteration during the Pliocene and Pleistocene periods. Prolonged freshwater alterations have resulted in many diagenetic overprints that obscure early diagenetic products. This study investigates the sequence of the diagenetic processes and products in the terrace deposits using five long cores and 14 short cores taken from these different reef terraces. The lithologic changes in the cores were documented for reconstruction of the original depositional frameworks prior to embarking on a diagenetic study. Both textural and geochemical changes were examined within all four …

Development And Validation Of A Music-Based Attention Assessment For Patients With Traumatic Brain Injury, Eunju Jeong

Open Access Dissertations

Impairments in attention are commonly seen in individuals with traumatic brain injury (TBI). While attention assessment measurements have been developed rigorously and utilized frequently in cognitive neurorehabilitation, there is a paucity of auditory attention assessment instruments that are ecologically valid and that assess different subtypes of attention. Yet, deficits in auditory attention can severely limit everyday functioning, negatively impact work and personal relationships and compromise personal safety. The purpose of this study was to develop and to investigate the psychometric properties of a Music-based Attention Assessment (MAA) instrument. The MAA is a multiple choice, melodic contour identification test, designed to …

Objecting Objectification: Finding The Links Between Self-Objectification, Views On Harassment, And Agreement With Traditional Sex Roles, Amy M. Bishop

Mahurin Honors College Capstone Experience/Thesis Projects

The purpose of this study is to explore the relationships between self-objectification levels, opinions on the impact of non-violent stranger sexual harassment on a personal and societal level, and agreement with traditional gender roles in college women. College women at Western Kentucky University were surveyed using the Objectified Body Consciousness Scale, the Social Roles Questionnaire, and original scales to measure views of street harassment. The hypotheses that viewing stranger harassment as both individually direct and complimentary would be positively correlated with self- objectification, and viewing it as innocuous in society were supported with correlation coefficients of r(103) = .211, p …

Is Diesel A Dirty Word? Examing The Communication And Public Relations Challenges Faced By Auto Manufacturers Who Want To Introduce Small Diesel Engines To The American Market, Christopher Nelson

Theses and Dissertations

Cars with small diesel engines make up a large part of the automobile market in virtually every region of the world but the United States. In this study, the researcher sought to determine if there are preexisting attitudes toward diesel fuel and engines among American consumers and whether those attitudes affect consumers' expressed opinions (i.e. buying habits) which contribute to that disparity. The researcher carried out two studies. The first was a modified Delphi study of public relations professionals in the automotive field. Respondents were given several basic questions regarding diesel engines in the American market followed by a series …
