Quasi-Platonic Psl2(Q)-Actions On Closed Riemann Surfaces, Sean A. Broughton

Mathematical Sciences Technical Reports (MSTR)

This paper is the first of two papers whose combined goal is to explore the dessins d'enfant and symmetries of quasi-platonic actions of PSL₂(q). A quasi-platonic action of a group G on a closed Riemann S surface is a conformal action for which S/G is a sphere and S->S/G is branched over {0, 1,infinity}. The unit interval in S/G may be lifted to a dessin d'enfant D, an embedded bipartite graph in S. The dessin forms the edges and vertices of a tiling on S by dihedrally symmetric polygons, generalizing the idea of a …

Relative Proper Motions In The Rho Ophiuchi Cluster, Bruce Wilking, Frederick Vrba, Timothy Sullivan

Physics Faculty Works

Near-infrared images optimized for astrometry have been obtained for four fields in the high-density L 1688 cloud core over a 12 year period. The targeted regions include deeply embedded young stellar objects (YSOs) and very low luminosity objects too faint and/or heavily veiled for spectroscopy. Relative proper motions in R.A. and decl. were computed for 111 sources and again for a subset of 65 YSOs, resulting in a mean proper motion of (0,0) for each field. Assuming each field has the same mean proper motion, YSOs in the four fields were combined to yield estimates of the velocity dispersions in …

Production And Economic Efficiencies Of Intensified Cow–Calf Production Management Systems, Jason M. Warner

Department of Animal Science: Dissertations, Theses, and Student Research

The objective of four experiments conducted was to evaluate production and economic efficiencies of intensified cow-calf production management systems. The first experiment tested the effect of calf age at weaning on cow and calf performance and feed utilization at 2 locations. Body weight change from early to conventional weaning time was greater for early-weaned cows. Cow BCS and conception rates were not impacted by weaning. Calf BW at conventional weaning time was greater for conventionally-weaned calves than early-weaned calves at ARDC, but greater for early-weaned than conventionally-weaned calves at PHREC. Calf ADG per unit of total feed energy intake was …

Advances In Autonomous-Underwater-Vehicle Based Passive Bottom-Loss Estimation By Processing Of Marine Ambient Noise, Lanfranco Muzi

Dissertations and Theses

Accurate modeling of acoustic propagation in the ocean waveguide is important to SONAR-performance prediction, and requires, particularly in shallow water environments, characterizing the bottom reflection loss with a precision that databank-based modeling cannot achieve. Recent advances in the technology of autonomous underwater vehicles (AUV) make it possible to envision a survey system for seabed characterization composed of a short array mounted on a small AUV. The bottom power reflection coefficient (and the related reflection loss) can be estimated passively by beamforming the naturally occurring marine ambient-noise acoustic field recorded by a vertical line array of hydrophones. However, the reduced array …

The Biology Of Eastern Kingbirds At Malheur National Wildlife Refuge: Survival, Reproduction, And Testosterone Secretion, Lucas J. Redmond

Dissertations and Theses

This dissertation presents the results of a study that I undertook to better understand the breeding biology of Eastern Kingbirds (hereafter, kingbirds) at Malheur National Wildlife Refuge in southeastern Oregon from 2003 to 2009. Kingbirds are long-distance migratory songbirds that breed across much of North America. This species is socially monogamous but, via frequent extra-pair copulations, is genetically polygamous. Kingbirds exhibit relatively high breeding site fidelity, often returning to the same tree to nest in subsequent years. Both members of a pair provide parental care, but there are often specific duties performed by both male and female kingbirds. For example, …

Treatise On Seismicity And Velocity Structure Of The Northern Mississippi Embayment, Akramalsadat Mostafanejad

Electronic Theses and Dissertations Archive

Seismicity of the New Madrid seismic zone, velocity structure of the northern Mississippi Embayment and extent of lithospheric discontinuities have been investigated in this work. Spatial variations of seismic b-value in the NMSZ have been determined. A region of high b-value (b~1.8) in the northern segment of the Reelfoot fault has been found which reflects higher frequency in the occurrence rate of small earthquakes. This is attributed to fault creep in a medium with high silica content, high pore fluid pressure and extensive velocity heterogeneity. In another study, power spectral ratios of horizontal to vertical (H/V) and vertical to horizontal …

Influence Of Locus Of Control, Work Motivation And Information Use On Decision- Making Of Managers In The Aviation Industry In Nigeria., Olaronke O. Fagbola Dr, Sunday O. Popoola Dr

Library Philosophy and Practice (e-journal)

This study discusses the influence of locus of control, work motivation and information use on decision making of managers in the aviation industry in Nigeria. Stratified random sampling method was used to select 1238 managers from five aviation parastatals in Nigeria out of which 945 responded. The response rate achieved was 76.3 percent. The study found that locus of control, work motivation and information use significantly influence decision making of the respondents. It is therefore recommended that aviation industry administrators and most especially policy makers in the industry should give due attention to locus of control, work motivation and information …

The Efficiency And Productivity Analysis Of Large Logistics Providers Services In Korea, Sunchon National University, Yong Joo Lee

Finance and Supply Chain Faculty Scholarship

In the fierce competition at the global logistics markets, Korean logistics providers were deemed more vulnerable than global logistics providers in terms of the quality and price competitiveness. To strengthen their competitiveness, logistics providers in Korea have focused on delivering integrated logistics services. In this regard, the Korean government has enacted the “Integrated Logistics Industry Certification Act” in 2006 to assist integrated logistics providers to offer logistics services based on their specialization and differentiation. It has been several years since the system was implemented, and the evaluation of the system implementation was necessary. Hence, in our study, we attempt to …

Ice Nucleation At The Contact Line Triggered By Transient Electrowetting Fields, Fan Yang, Raymond Shaw, Colin Gurganus, Su Kong Chong, Yoke Khin Yap

Department of Physics Publications

Supercooled water is found to have a significantly enhanced freezing temperature during transient electrowetting with electric fields of order 1 V/μm. High speed imaging reveals that the nucleation occurs randomly at the three-phase contact line (droplet perimeter) and can occur at multiple points during one freezing event. Possible nucleation mechanisms are explored by testing various substrate geometries and materials. Results demonstrate that electric field alone has no detectable effect on ice nucleation, but the moving boundary of the droplet on the substrate due to electrowetting is associated with the triggering of nucleation at a much higher temperature.

Canonoid And Poissonoid Transformations, Symmetries And Bihamiltonian Structures, Giovanni Rastelli, Manuele Santoprete

Mathematics Faculty Publications

We give a characterization of linear canonoid transformations on symplectic manifolds and we use it to generate biHamiltonian structures for some mechanical systems. Utilizing this characterization we also study the behavior of the harmonic oscillator under canonoid transformations. We present a description of canonoid transformations due to E.T. Whittaker, and we show that it leads, in a natural way, to the modern, coordinate-independent definition of canonoid transformations. We also generalize canonoid transformations to Poisson manifolds by introducing Poissonoid transformations. We give examples of such transformations for Euler’s equations of the rigid body (on so*(3) and so*(4)) and for an integrable …

Density-Based Clustering Of High-Dimensional Dna Fingerprints For Library-Dependent Microbial Source Tracking, Eric Johnson

Master's Theses

As part of an ongoing multidisciplinary effort at California Polytechnic State University, biologists and computer scientists have developed a new Library-Dependent Microbial Source Tracking method for identifying the host animals causing fecal contamination in local water sources. The Cal Poly Library of Pyroprints (CPLOP) is a database which stores E. coli representations of fecal samples from known hosts acquired from a novel method developed by the biologists called Pyroprinting. The research group considers E. coli samples whose Pyroprints match above a certain threshold to be part of the same bacterial strain. If an environmental sample from an unknown host animal …

Five Seemingly Insurmountable Challenges Related To Attaining Long-Term Value From Theorizing About Information Systems, Steven Alter

Business Analytics and Information Systems

Recent articles such as Avison and Malaurent (2014) and Grover and Lyytinen (2015) question taken-for-granted assumptions about the centrality of theory in research published in leading journals and the near necessity of following repetitive scripts that sometimes are an obstacle to creativity. This paper goes a step further by providing examples and observations that illustrate five seemingly insurmountable challenges related to attaining long-term value from theorizing about information systems.

1) Divergent definitions of basic terms makes it extremely difficult to accumulate IS knowledge.

2) The IS discipline seems to take for granted that knowledge must take the form of theory. …

Online Versus Face-To-Face Nutrition Courses At A Community College: A Comparative Study Of Learning Outcomes, Solomon Kumbong Nfor

Theses & Dissertations

Students have been gravitating towards the Online Learning Environment (OLE). The preference for online learning models (OLM) among students has grown more rapidly than for traditional face-to-face models in community colleges in the United States of America. Research about OLMs has focused on teaching efficiency and effectiveness to support the growth of online education. Administrators and teachers have continually sought to gain more knowledge about this issue, especially with concerns regarding engagement of students in an online learning environment. Increased student dissatisfaction with online learning models, a high withdrawal rate, and inadequate student-learning outcomes are some of the factors that …

Cooling Atomic Gases With Disorder, Ehsan Khatami, Thereza Paiva, Shuxiang Yang, Valéry Rousseau, Mark Jarrell, Juana Moreno, Randall Hulet, Richard Scalettar

Faculty Publications

Cold atomic gases have proven capable of emulating a number of fundamental condensed matter phenomena including Bose-Einstein condensation, the Mott transition, Fulde-Ferrell-Larkin-Ovchinnikov pairing, and the quantum Hall effect. Cooling to a low enough temperature to explore magnetism and exotic superconductivity in lattices of fermionic atoms remains a challenge. We propose a method to produce a low temperature gas by preparing it in a disordered potential and following a constant entropy trajectory to deliver the gas into a nondisordered state which exhibits these incompletely understood phases. We show, using quantum Monte Carlo simulations, that we can approach the Néel temperature of …
