Microstructure Design Of A Two Phase Composite Using Two-Point Correlation Functions, Brent L. Adams, H. Garmestani, G. Saheli

Faculty Publications

This work has been funded under the AFOSR Grant no. F49620-03-1-0011 and Army Research Lab contract no. DAAD17-02-P-0398 and DAAD 19-01-1-0742. Two-point distribution functions are used here as to introduce "Microstructure Sensitive Design" in two-phase composites. Statistical distribution functions are commonly used for the representation of microstructures and also for homogenization of materials properties. The use of two-point statistics allows the composite designer to include the morphology and distribution in addition to the properties of the individual phases and components. Statistical continuum mechanics is used to make a direct link between the microstructure and properties (elastic and plastic) in terms …

Prelude To The Pearl: Sweeping Events Leading To The Discovery Of The Joseph Smith Papyri, Kerry M. Muhlestein

Faculty Publications

In a general presentation, Elder John A. Widtsoe of the Quorum of the Twelve Apostles taught that "throughout all the ages of history the hand of God has overruled the actions of mankind, that nothing is done except as the Lord may use it for the accomplishment of his mighty purposes. The things accomplished by humanity become in the end God's accomplishments, as he makes use of them in working out his infinite purposes. Even the great movements of nations and armies often serve to accomplish the workings of the Lord, such as when the empire of Assyria rose to …

Taking Assessment On The Road: Utah Academic Librarians Focus On Distance Learners, Allyson Washburn, Rob Morrison

Faculty Publications

This paper presents the results of focus groups conducted by Utah academic librarians at branch campuses in Utah. Librarians met with distance learners on-site to gain insights into their information-seeking behavior and to learn if they are using library services. Students rely heavily on the web for information and also utilize known resources in friends and family. Marketing and publicizing library services through classes and at the delivery sites is vital. Students appreciate the services libraries offer and strongly prefer face-face instruction and direct assistance from a librarian.

Guided Model Checking With A Bayesian Meta-Heuristic, Michael D. Jones, Peter Lamborn, Kevin Seppi

Faculty Publications

This paper presents a formal verification algorithm for finding errors in models of complex concurrent systems. The algorithm improves explicit guided model checking by applying the Empirical Bayes method to revise heuristic estimates of the distance from a given state to an error state. Guided search using the revised estimates finds errors with less search effort than the original estimates.

Uranium Oxide As A Highly Reflective Coating From 100-400 Ev, Richard L. Sandberg, David D. Allred, Luke J. Bissell, Jed E. Johnson, R. Steven Turley

Faculty Publications

We present the measured reflectances (Beamline 6.3.2, ALS and LBNL) of naturally oxidized uranium and naturally oxidized nickel thin films from 100-460 eV (2.7 to 11.6 nm) at 5 and 15 degrees grazing incidence. These show that uranium as UO2, can fulfill its promise as the highest known single surface reflector for this portion of the soft x-ray region, being nearly twice as reflective as nickel in the 124-250 eV (5-10 nm) region. This is due to its large index of refraction coupled with low absorption. Nickel is commonly used in soft x-ray applications in astronomy and synchrotrons. (Its reflectance …

Coordinated Uav Target Assignment Using Distributed Tour Calculation, David H. Walker, Timothy W. Mclain, Jason K. Kowlett

Faculty Publications

In this chapter a method for assigning unmanned aerial vehicle agents to targets through the use of preplanned vehicle tours is presented. Assignments are based on multi-target tours that consider the spread of the targets and the sensor capabilities of the vehicles. In this way, the individual agents and the team as a whole make better use of team resources and improve team cooperation. Planning and assignments are accomplished in reasonable computational time through the use of heuristics to reduce the problem size.

Human Capital And Learning As A Source Of Sustainable Competitive Advantage, Nile W. Hatch, Jeffrey H. Dyer

Faculty Publications

This paper seeks to identify the sources of wide and persistent variations in learning performance in the semiconductor manufacturing industry. In the resource-based view of the firm, human capital is frequently assumed to contribute to competitive advantage due to its inimitability based on its intangible, firm-specific, and socially complex nature. Consistent with this view, we find that investments in firm-specific human capital have a significant impact on learning and firm performance. More specifically, human capital selection (education requirements and screening), development through training, and deployment significantly improve learning by doing, which in turn improves performance. However, we find that acquiring …

The Diaries Of Mary Lois Walker Morris, Melissa Lambert Milewski

Theses and Dissertations

An edited transcription of the 1879 to 1887 diaries of Mary Lois Walker Morris (1835-1919). Mary Lois, a plural wife in 19th century Utah, went in and out of hiding between 1885 and 1887 to protect her husband Elias Morris from prosecution for illegal cohabitation. Her daily diaries culminate with the court trial of her husband for illegal cohabitation in September 1887. At the trial, she testified falsely, stating that she had been separated from her husband since the beginning of 1883, when in fact the couple did not separate until May of 1885. As a result, her husband was …

Re-Immigration To Denmark: The Challenge Of Reintegration, Jette Mackintosh

The Bridge

Over the years, I have known a lot of happy and contented immigrants to the United States, and this made me wonder what motivated return migration. It was a completely uncharted field, so it was an exciting challenge when, in 1996, I was asked to give a paper on the subject at an international conference in Gothenburg. It has since developed into a full-scale research project and a book.

Spatial Variability Of Groundwater Recharge - I. Is It Really Variable?

Journal of Spatial Hydrology

The spatial variability of recharge is an important consideration in estimating recharge especially as all methods of estimating it are 'point' estimates and in most places recharge varies in space. This paper along with the accompanying paper attempts to find a suitable answer to the question of taking this variability into account in estimating groundwater recharge. This paper attempts to determine if recharge is actually varying in space and that this is 'true' variability and that it is not an artefact of the method used for estimating recharge. It also pulls together information on spatial variability of recharge reported by …

Engaging Reluctant Readers: Let's Try Nonfiction, Kathryn Fitzgerald

The Utah English Journal

"If it's not fiction, it's not reading." Starkly put, that was my concept of worthwhile literature until recently with, I think, good reason. Not only do we English teachers love reading good fiction, but we know that valuable lessons are taught through literature: students learn about themselves and their own life choices through reading about recognizable fictional characters; they experience cultures and times other than their own by reading diverse current and classical fiction; they learn to think critically about the beliefs and values they are exposed to through fiction (and to reflect on their own beliefs); they learn empathy …

The Longterm Effects Of Television Mediation On Lds Young Single Adults: An Exploratory Study, Jennia Parkin

Theses and Dissertations

This exploratory study examines what Latter-day Saint young single adults remember about their parents mediating the television and its use, and how those recollections contribute to their current attitudes and values toward the media, as well as their media choices. A stratified random sample of 267 LDS young single adults across the United States and outside the state of Utah responded to a cross sectional mail or online survey. The three mediation styles established by Valkenburg, Krcmar, Peeters, and Marseille (1999)—Restrictive, Instructive, and Coviewing—were used as the independent variables while scales assessing television offensiveness levels, attitudes, orientation, and usage were …

Integrating Perception, Language And Problem Solving In A Cognitive Agent For A Mobile Robot., Deryle W. Lonsdale, D. Paul Benjamin, Damian M. Lyons

Faculty Publications

We are implementing a unified cognitive architecture for a mobile robot. Our goal is to endow a robot agent with the full range of cognitive abilities, including perception, use of natural language, learning and the ability to solve complex problems. The perspective of this work is that an architecture based on a unified theory of robot cognition has the best chance of attaining human-level performance.

This agent architecture is an integration of three theories: a theory of cognition embodied in the Soar system, the RS formal model of sensorimotor activity and an algebraic theory of decomposition and reformulation.

These three …

Sponsorship: INEEL. This paper presents a coordinated control strategy for autonomous monitoring of a dynamically changing hazardous spill. The control strategy is a two level hierarchy that uses use coordination variables to communicate between the levels. The upper level is a resource allocator. The lower level consists of several "commanders" each with a possibly different objective. A physical description of the problem is given, as well as the methods of spill modeling and simulation. Tactics for locating, gravitating to and circling the spill are presented. Finally, both simulation and hardware results are given.

Termination-Dependent Diversity Performance Of Coupled Antennas: Network Theory Analysis, Michael A. Jensen, Jon W. Wallace

Faculty Publications

A new analysis of mutually coupled diversity antenna systems is presented that includes the effects of coupling on the radiation pattern and received power. This analysis, based upon the network scattering parameters, makes use of the singular value decomposition to both specify the characteristics of and analyze terminated antenna networks. The approach facilitates a simplified proof of the multiport conjugate matching condition as well as development of expressions for diversity performance as a function of various impedance terminations. Application of the analysis to coupled dipole antennas characterized using full-wave electromagnetic analysis leads to a comprehensive examination of the diversity performance …

Wideband Channel Model For Aeronautical Telemetry, Christian Bettweiser, Adam Davis, Michael D. Rice

Faculty Publications

A multipath channel model for wideband aeronautical telemetry links is presented. Channel sounding data were collected at Edwards AFB, CA, at both L-band and lower S-band. Frequency domain analysis techniques were used to evaluate candidate channel models. The channel model is composed of three propagation paths: a line-of-sight direct path and two specular reflections. The first specular reflection is characterized by a relative amplitude of 70% to 96% of the line-of-sight amplitude and a delay of 10—80 ns. This path is the result of “ground bounces” off the dry lake bed at Edwards and is a typical terrain feature at …

Introduction, John Mark Nielsen

The Bridge

In 1992 a conference was held in Aalborg, Denmark, sponsored by the Danes Worldwide Archives (now The Danish Emigration Archive). The purpose of this conference was to celebrate the centennial of the birth of Marcus Lee Hansen, an American historian of Danish descent. Hansen had played a major role in challenging historians to consider the wider forces of migration. Before him historians tended to focus on immigrants in America while paying little attention to the conditions that had motivated individuals to emigrate from the lands of their birth. Although Hansen did not discuss this experience using the terms of "push …
