Refrigerated Wind Tunnel Tests on Surface Coatings for Preventing Ice Formation

This investigation was conducted to determine the effectiveness of various surface coatings as a means for preventing ice formations on aircraft in flight. The substances used as coatings for these tests are divided into two groups: compounds soluble in water, and those which are insoluble in water. It was found that certain soluble compounds were apparently effective in preventing the formation of ice on an airfoil model, while all insoluble compounds which were tested were found to be ineffective

A tribute to Frederick F. Knowlton

Dr. Fredrick F. Knowlton officially retired on March 31, 2007, with well over 45 years of service to the USDA/Wildlife Services. Fred worked at Wildlife Services’ National Wildlife Research Center Field Station in Logan, Utah, for 35 years alone! His work on coyotes and other species has had an extraordinary impact on the science and management of coyotes. Things that we take for granted today about the life history of coyotes were the result of Fred’s tireless ambition to understand these animals and to improve our ability to manage them. One of our agency’s first Ph.D. hires, Fred produced about 100 papers and reports during his career, and as a professor at Utah State University he mentored many students through the years

Designing, Building, and Modeling Maneuverable Applications within Shared Computing Resources

Extending the military principle of maneuver into war-fighting domain of cyberspace, academic and military researchers have produced many theoretical and strategic works, though few have focused on researching actual applications and systems that apply this principle. We present our research in designing, building and modeling maneuverable applications in order to gain the system advantages of resource provisioning, application optimization, and cybersecurity improvement. We have coined the phrase “Maneuverable Applications” to be defined as distributed and parallel application that take advantage of the modification, relocation, addition or removal of computing resources, giving the perception of movement. Our work with maneuverable applications has been within shared computing resources, such as the Clemson University Palmetto cluster, where multiple users share access and time to a collection of inter-networked computers and servers. In this dissertation, we describe our implementation and analytic modeling of environments and systems to maneuver computational nodes, network capabilities, and security enhancements for overcoming challenges to a cyberspace platform. Specifically we describe our work to create a system to provision a big data computational resource within academic environments. We also present a computing testbed built to allow researchers to study network optimizations of data centers. We discuss our Petri Net model of an adaptable system, which increases its cybersecurity posture in the face of varying levels of threat from malicious actors. Lastly, we present work and investigation into integrating these technologies into a prototype resource manager for maneuverable applications and validating our model using this implementation

KEKF R1 Reservoir - West Delta Block 84, Plaquemines Parish, Louisiana - an analysis and confirmation of bypassed primary and secondary reserves

West Delta Block 84 Field is located off the coast of Plaquemines Parish, Louisiana. The intent of this endeavor is to prove that the two of the reservoirs, the KE-1 and KF-1, form a single communicating reservoir, the KEKF-R1; that a waterflood into the KF-1 reservoir was ineffective; that oil reserves were bypassed; and that a portion of these bypassed oil reserves can be recovered without drilling new wells. Comparisons between pre-seismic and post-seismic geological interpretations were studied, a thorough volumetric analysis was performed with a subsequent material balance calculations and a reservoir computer simulation was performed. Once a history match was made, prediction studies were performed for both remaining “primary” reserves and for secondary reserves recoverable through a new water-flood design and implementation. There are many new insights on this reservoir as a result of this study. First, the KE-1 and the KF-1 reservoirs are indeed one communicating reservoir. The KF-1 waterflood was inefficient and resulted in bypassed oil pay. Bypassed oil may be recovered through several techniques. Based on prediction runs on BOAST, the best case scenario analyzed thus far without additional drilling is an additional 1,600,000 barrels of oil. This study indicates that a small amount of old technology, in the form of a resurrection of a waterflood and a small amount of new technology, in the form of the Downhole Water Sink (DWS) method will greatly increase the ultimate recovery of the “lost” reserves. This study has provided sufficient evidence and documentation to justify the need for additional research and study of this reservoir. More detailed recovery strategies should be prepared, the DWS technology should be studied in more detail and a more detailed grid should be prepared for the reservoir

Evaluating the Labor Supply and Migration Effects of the Interstate Medical Licensure Compact

A growing body of literature suggests that occupational licensing distorts economic behavior through various mechanisms, such as inflating prices and inhibiting interstate mobility. To combat some of these ill-effects, policymakers have turned to interstate compacts as a way to promote uniformity in licensing requirements across states and facilitate license portability. Despite the development of interstate compacts for numerous licensed occupations and professions, evidence of their efficacy in the literature is thin. Based on data from over 70,000 physicians from 2012 to 2018, I construct a difference-in-differences model to estimate the effects of the adoption of the Interstate Medical Licensure Compact (IMLC) on labor supply and interstate mobility. The results suggest that labor supply and migration/commuting did not significantly change following IMLC adoption

The Future of Wildlife Damage Management

In January 2018, I retired after a 35-year career in the wildlife damage management profession. I would like to off er my perspective on what the profession was like when I began my career, what it’s like currently, and what I think the future holds. Thirty-five years ago in our program, wildlife damage management activities across the country focused primarily on protecting livestock from predators as well as protecting many agricultural crops like corn, rice, and sunflowers from bird damage. Since transferring from the Department of the Interior to the Department of Agriculture in 1986, we have seen a significant increase in the range and extent of wildlife damage requests for services. In addition to the protection of agricultural resources, the program has expanded services to address other agricultural resources such as aquaculture, forestry, and truck crops. Our personnel became involved in the protection of public health and safety by working at airports to prevent wildlife–aircraft strikes, wildlife disease surveillance activities involving avian influenza, chronic wasting disease, rabies, and many other diseases transmitted by wildlife. We also began emphasizing the protection of natural resources such as threatened and endangered species, as well as property

Drum taps: a performance guide to the song cycle by Richard Pearson Thomas

Smith, William Clay, B.A., Campbellsville University, 2000 Master of Arts in Music, Campbellsville University, 2001 Doctor of Musical Arts, Fall Commencement, 2009 Major: Music Drum Taps: A Performance Guide to the Song Cycle by Richard Pearson Thomas Written Document directed by Kirkpatrick Professor of Voice Robert Grayson Pages in written document, 147. Words in abstract, 120. ABSTRACT Composer Richard Pearson Thomas has gained recognition from his art song “I Never Saw a Moor” and his participation in the AIDS Quilt Songbook, but his song cycle Drum Taps has often been overlooked. This document examines the baritone song cycle which was completed in 1990. The study begins with biographical synopses of the composer and the poet, Walt Whitman, as well as brief information about the poetry from which Drum Taps is drawn. Subsequent chapters focus on the five songs of the cycle, studying each song’s text, sound, harmony, melody, rhythm, growth throughout the piece, and performance practice. The information is presented as an aid to preparing and performing the work. Additionally, an appendix presents the composer’s complete works

Ice Prevention on Aircraft by Means of Impregnated Leather Covers, Special Report

The National Advisory Committee for Aeronautics is testing the effectiveness of a method to prevent the formation of ice on airplanes. The system makes use of a leather cover that is attached to the leading edge of the wing. A small tube, attached to the inner surface of the leather, distributes to the leading edge a solution that permeates throughout the leather and inhibits the formation of ice on the surface. About 25 pounds of the liquid per hour would be sufficient to prevent ice from forming on a wing of 50-foot span. The additional gross weight of the system will not be excessive. The tests are not yet completed but the method is thought to be practicable for the wing and it may also be adaptable to the propeller
