Open Source Software For Commercial Off-The-Shelf Gps Receivers, Andrew Greenberg

Dissertations and Theses

Inexpensive and commercially available Global Positioning System (GPS) receivers can be used in novel applications, such as nanosatellites and unmanned aerial vehicles (UAVs), by modifying the receiver's software. Unfortunately, typical GPS software development systems cost tens of thousands of dollars and have restrictive license agreements, such as non-disclosure agreements, for both their hardware and software. This thesis describes the design and construction of an open source GPS receiver development system that addresses these unnecessary restrictions. For the first time, any developer with a PC, a commercially available GPS receiver, and this development system can quickly and easily develop software for …

Lessons About Recruiting Primary Care Practices To Domestic Violence Trainings, Jim Winkle, Christina Nicolaidis

School of Social Work Faculty Publications and Presentations

A few studies have evaluated continuing medical education programs on domestic violence, but they have generally used convenience samples and have not provided information regarding their recruitment strategies or the proportion of eligible providers that attended the interventions. (Davis, Kaups, Campbell, & Parks, 2000; Haney, Kachur, & Zabar, 2003; McCauley, Jenckes, & McNutt, 2003) In one study that did provide such information, investigators faxed invitations to 1887 physicians, of which only 121 (6%) responded that they were interested despite a $50-$100 incentive to participate in a short on-line program with free Continuing Medical Education (CME) credits (Harris, Kutob, Surprenant, Maiuro, …

Locality, Network Control And Anomaly Detection, Jim Binkley

Computer Science Faculty Publications and Presentations

Ourmon is a near real-time network monitoring and anomaly detection system that captures packets using port-mirroring on Ethernet switches. It primarily displays data via web graphics using either RRDTOOL stripcharts or via histograms for top talker style graphs. We have developed a theory that network scanning launched primarily by worm programs including TCP and UDP scanners may be caught by monitoring network control data including TCP control packets (SYNS, FINS, RESETS) and ICMP errors, or by monitoring certain carefully chosen metadata such as the flow count itself. In this paper we concentrate on TCP and present a ”flow tuple” focused …

An Environmentally Enlightened Accounting, Jesse Dillard, Darrell Brown, Scott Marshall

Business Faculty Publications and Presentations

Environmental stewardship must become a primary concern if management is to adequately fulfill its societal responsibilities. Management and accounting information systems must aggressively respond to these emerging requirements in order to support adequately the associated information needs as well as to design organizational systems that motivate and facilitate desired behavior. Our purpose here is to consider a framework useful for developing environmentally enlightening management and accounting information systems that take into account alternative environmental perspectives. The framework can be used to develop prototypes representing different levels of environmental enlightenment and, as such, can provide general guidance for moving collectives and …

A Dialect Study Of Oregon Norms, Lisa Wittenberg Hillyard

Dissertations and Theses

The pioneers and settlers of the Oregon Territory were not of one ilk. They came from various places and brought their separate speech patterns with them. This study sought to identify which major North American English dialect was present in the first half of the 20^th century in Oregon. Analysis relied on the descriptions for the Southern, Northern, Midlands, and Western dialects. Some dialect features have acoustic measurements attached to their descriptions, and others do not. The analytical process was based on acoustic measurements for vowel classes and individual tokens, as well as global observations about the place of …

Third Extrusion Project: Project Analysis, Ingrid Suarez

Engineering and Technology Management Student Projects

This paper uses a case study approach to analyze the Third Extrusion Project (TEP) in Cerro Matoso S.A (CMSA). The TEP was chosen to be analyzed because of the importance to the company, the quality of the project management, and the impact in CMSA’s business. The analysis was focused on the managerial and organizational aspects, rather than on technical topics. It was based on the Strategic Project Leadership framework proposed by Dr. Aaron Shedar.

BHP Billiton, the parent organization of CMSA, is one of the world’s premier mining companies. Its project management office aims to ensure that the project management …

Can Cooperative Service Solve The Grey Literature Challenge?, Sherry Buchanan, Cyril Oberlander, Rose M. Jackson

Library Faculty and Staff Publications and Presentations

With the surge of student and faculty reliance on the Internet and search engines like Google as sources for bibliographies, researchers expect reference desk staff to quickly locate obscure materials. In this article, we explore the interplay between reference and interlibrary loan services in light of post-modern research styles, and how reference and interlibrary loan (distinct service points) can seamlessly address grey literature research needs.

Enhancements To Crisp Possibilistic Reconstructability Analysis, Anas Al-Rabadi, Martin Zwick

Complex Systems Faculty Publications and Presentations

Modified Reconstructibility Analysis (MRA), a novel decomposition within the framework of set-theoretic (crisp possibilistic) Reconstructibility Analysis, is presented. It is shown that in some cases while 3-variable NPN-classified Boolean functions are not decomposable using Conventional Reconstructibility Analysis (CRA), they are decomposable using Modified Reconstructibility Analysis (MRA). Also, it is shown that whenever a decomposition of 3-variable NPN-classified Boolean functions exists in both MRA and CRA, MRA yields simpler or equal complexity decompositions. A comparison of the corresponding complexities for Ashenhurst-Curtis decompositions, and Modified Reconstructibility Analysis (MRA) is also presented. While both AC and MRA decompose some but …

Teabag: A Debugger For Curry, Stephen Lee Johnson

Dissertations and Theses

This thesis describes TeaBag, which is a debugger for functional logic computations. TeaBag is an accessory of a virtual machine currently under development. A distinctive feature of this machine is its operational completeness of computations, which places novel demands on a debugger. This thesis describes the features of TeaBag, in particular the handling of non-determinism, the ability to control nondeterministic steps, to remove context information, to toggle eager evaluation, and to set breakpoints on both functions and terms. This thesis also describes TeaBag's architecture and its interaction with the associated virtual machine. Finally, some debugging sessions of defective programs are …

Getting Your Money's Worth: What Early Childhood Directors Should Know About Working With Mental Health Professionals, Beth L. Green, Maria C. Everhart, Lynwood Gordon

School of Social Work Faculty Publications and Presentations

The increasing numbers of young children with challenging behaviors and emotional problems have led many child care providers and early childhood education programs to employ or contract with mental health professionals (Lavigne et al., 1996). Head Start Programs, for example, are required by federal performance standards to utilize services of mental health professionals that are "sufficient" to meet the needs of children and families. However, there has been little research to help program managers make informed choices about who might provide the best services, what services are most important to support staff and families, and how to make the best …

Sediment Nutrient Accumulation And Nutrient Availability In Two Tidal Freshwater Marshes Along The Mattaponi River, Virginia, Usa, Jennifer L. Morse, J. Patrick Megonigal, Mark R. Walbridge

Environmental Science and Management Faculty Publications and Presentations

Sediment deposition is the main mechanism of nutrient delivery to tidal freshwater marshes (TFMs). We quantified sediment nutrient accumulation in TFMs upstream and downstream of a proposed water withdrawal project on the Mattaponi River, Virginia. Our goal was to assess nutrient availability by comparing relative rates of carbon (C), nitrogen (N), and phosphorus (P) accumulated in sediments with the C, N, and P stoichiometries of surface soils and above ground plant tissues. Surface soil nutrient contents (0.60–0.92% N and 0.09–0.13% P) were low but within reported ranges for TFMs in the eastern US. In both marshes, soil nutrient pools and …

South Park Blocks Area Development Strategy: Priorities And Actions To Strengthen Neighborhood Identity, Lisa Abuaf, Natasha Detweiler, Steve Faust, Jennifer Mannhard, Dan Zalkow

Master of Urban and Regional Planning Workshop Projects

Past and current planning efforts by the City of Portland, such as the South Park Blocks Urban Renewal Area and the West End plan, have sought to promote new mixed-use development through increasing the residential density and investment in the area. The West End plan focused primarily on the area north of SW Salmon Street and the urban renewal area currently does not have a standing advisory committee to represent the Downtown neighborhood’s interests. This project consists of a neighborhood analysis to distill the identity of the area, an identification of the opportunities and challenges to development, and a strategy …

Fault Localization In Reversible Circuits Is Easier Than For Classical Circuits, Kavitha Ramasamy, Radhika Tagare, Edward Perkins, Marek Perkowski

Electrical and Computer Engineering Faculty Publications and Presentations

There is recently an interest in test generation for reversible circuits, but nothing has been published about fault localization in such circuits. This paper deals with fault localization for binary reversible (permutative) circuits. We concentrate on functional test based fault localization, to detect and locate “stuck-at” faults in a reversible circuit by creating an adaptive tree. A striking property of reversible circuits is that they exhibit “symmetric” adaptive trees. This helps considerably by being able to generate only half of the tree, and the other half is created as the mirror image of the first half. Because each test covers …

Toward A Sound Integration Of Isabelle With A Combined Decision Procedure, Tom Harke

Computer Science Faculty Publications and Presentations

I present work on a project to integrate Isabelle, an extremely versatile interactive proof assistant, with a combined decision procedure, the Cooperating Validity Checker (CVC). Isabelle is sound and flexible, however it is often tedious to use. CVC is fully automatic, but only handles decision problems expressible over a relatively weak set of theories including linear arithmetic, uninterpreted functions, data types, and firstorder quantifier-free logic. My goal is to increase the amount of automation in Isabelle, by making it use CVC as an oracle for such problems, but without compromising Isabelle’s soundness.

In this paper I report on the progress …

Waldo Lake Research In 2003, Mark D. Sytsma, John Rueter, Richard Petersen, Roy Koch, Scott A. Wells, Rich Miller, Laura Johnson, Robert Leslie Annear

Civil and Environmental Engineering Faculty Publications and Presentations

This report summarizes the first year of an effort to develop a more complete understanding of the physical, chemical, and biological characteristics that drive the ecological processes of Waldo Lake. Modern limnology recognizes the importance of watershed processes as well as in- lake processes in lake ecosystem functioning. Therefore, the approach included consideration of watershed hydrology and forcing functions that determine hydrodynamics of the system as well physical and chemical factors that may be important in regulating primary production in the lake. Data collected since 1998 was summarized and bathymetry of the basin was mapped using state-of-the-art digital depth sounding …
