Terahertz Scattering From Granular Material, Lisa M. Zurk, Brian Orlowski, Dale P. Winebrenner, Eric I. Thorsos, Megan R. Leahy-Hoppa, L. Michael Hayden Aug 2007

Terahertz Scattering From Granular Material, Lisa M. Zurk, Brian Orlowski, Dale P. Winebrenner, Eric I. Thorsos, Megan R. Leahy-Hoppa, L. Michael Hayden

Electrical and Computer Engineering Faculty Publications and Presentations

Terahertz (THz) imaging is emerging as a potentially powerful method of detecting explosive devices, even in the presence of occluding materials. However, the characteristic spectral signatures of pure explosive materials may be altered or obscured by electromagnetic scattering caused by their granular nature. This paper presents THz transmission measurements of granular systems representative of explosives and presents results from dense media theory that accurately explain the observed scattering response.

Recommendations for improving data collection were made. Each RTO-partner program is detailed individually in the appendices.


Information Technology Training In The Public Sector : Essential Planning Elements, Betty Jean Reynolds Jul 2007

Information Technology Training In The Public Sector : Essential Planning Elements, Betty Jean Reynolds

Dissertations and Theses

Information technology (IT) has revolutionized the workplace and the provision of government services, and rapidity of change makes IT training essential. Planning, however, can be haphazard, and public sector training might not fulfill training needs. Elements that are essential to planning for the success of IT training in the public sector were identified from the literature: IT training organization structure/training provider, methods of IT training delivery, assessment of IT training needs, IT training expenditures, specific IT training needs, and strategies for improving IT training.

IT directors of Oregon state agencies and chief information officers (CIOs) of exemplar states were surveyed …


Graduate Teaching Assistants' Statistical Knowledge For Teaching, Jennifer Ann Noll Jul 2007

Graduate Teaching Assistants' Statistical Knowledge For Teaching, Jennifer Ann Noll

Dissertations and Theses

This dissertation explores graduate teaching assistants’ (TAs’) statistical knowledge for teaching. Data collection methods that enabled the exploration of TA s’ statistical knowledge for teaching include: (a) a task-based web survey administered to 68 TAs from 18 universities across the United States; and, (b) a series of three taskbased interviews with a subset of five TAs from the larger survey population. Through and Strauss, 1967), I investigated the ways in which TAs reason about sampling tasks, and how they think about teaching and student learning in relation to sampling ideas. Building on past research in statistics education on K-12 and …


Global Civil Society Finding Collective Voice In Diversity, Kristen Marie Magis Jul 2007

Global Civil Society Finding Collective Voice In Diversity, Kristen Marie Magis

Dissertations and Theses

The research question that forms the basis of this dissertation is: "What characteristics do members of Global Civil Society define as critical to the successful functioning of coalition processes designed to generate specific policy positions?" The dissertation's objective is to develop a canon of knowledge about these critical characteristics.

The relative lack of research on the question of the internal organization and operations of GCS coalitions necessitated the use of inductive methodology. Three sources of data were utilized; interviews with knowledgeable persons in Global Civil Society, a conference of GCS experts, and papers commissioned for the conference. The data were …

Asset Mapping: Community Geography Project

Making community development as democratic as possible has long been a challenge for urban planners and municipalities alike. A number of obstacles stand in the way of greater community participation in the planning process and consequently communities who are best served by their design. Visual Preference Surveys (VPS) are a tool planners can use to increase participation in the design process within the communities they serve. This can result in community plans that more accurately reflect the wants or needs of its members. Relying heavily on image driven content, VPS offers communities a straightforward methodology that asks participants to rate …

Improving Arterial Performance Measurement Using Traffic Signal System Data, Michael Wolfe, Christopher Monsere, Peter Koonce, Robert L. Bertini Jul 2007

Improving Arterial Performance Measurement Using Traffic Signal System Data, Michael Wolfe, Christopher Monsere, Peter Koonce, Robert L. Bertini

Civil and Environmental Engineering Faculty Publications and Presentations

The characterization of the performance of freeways in real time and on a historical basis has been successfully achieved for many years. The ability to characterize arterial performance has been more elusive. Currently numerous applications of traffic management and traveler information systems include freeways but lack the ability to extend their operation to major arterials. This paper describes methods for quantifying arterial performance using data from signal system loop detectors. Included in the array of metrics are traffic density, total delay, predicted travel time, and signal coordination effectiveness. Methods for determining performance in these areas are adapted for use in …

Chemistry Faculty Publications and Presentations

The pH-sensitive contrast agent, GdDOTA-4AmP (Gd1) has been successfully used to map tissue pH by MRI. Further studies now demonstrate that two distinct chemical forms of the complex can be prepared depending upon the pH at which Gd3+ is mixed with ligand 1. The desired pH-sensitive form of this complex, referred to here as a Type II complex, is obtained as the exclusive product only when the complexation reaction is performed above pH 8. At lower pH values, a second complex is formed that, by analogy with an intermediate formed during the preparation of GdDOTA, we tentatively assign …


The Changing Paradigm Of Emergency Management : Improving Professional Development For The Emergency Manager, Robert Edward Grist Jun 2007

The Changing Paradigm Of Emergency Management : Improving Professional Development For The Emergency Manager, Robert Edward Grist

Dissertations and Theses

Throughout its short and remarkable history, emergency management has been subjected to a vast array of fast-moving and radical changes which have presented significant challenges to the men and women in this emerging profession. This study was designed to help determine the adequacy of their professional development to meet those challenges.

The study is framed within an environment where emergency managers face the pressure to professionalize; explore the world of risk, trust, and the distribution of power; confront revolutionary changes; and concern themselves with the social impact of disasters in their own communities. This study asks: "Do Emergency Managers feel …

From Prison To The Community : The Role Of Citizen Participation In Female Prisoner Reentry, Dana Roderick Torrey Jun 2007

From Prison To The Community : The Role Of Citizen Participation In Female Prisoner Reentry, Dana Roderick Torrey

Dissertations and Theses

Growing attention is being given to the design of programs for female prisoners to assist their successful reentry into the community upon the completion of their incarceration. However, current programs have been largely designed and implemented with the goal of seeking parolee compliance through mandatory rules and practices. Little emphasis is placed on preparing inmates to assume their duties as citizens and active participants in the lives of their community. In short, existing programs pay little attention to the importance of creating what I call for purposes of this study, “citizen participation”.

This study tests the importance of developing a …

Global Sourcing And Logistics, Martin Christopher, Fu Jia, Omera Khan, Carlos Mena, Erik Sandberg

Business Faculty Publications and Presentations

The sourcing of products from across the global marketplace is an increasing trend associated with economic development. This trend is the result of many independent decisions taken by firms around the world looking for new sources of competitive advantage. However, these decisions can also have unintended consequences, exposing the firms to hidden costs and risks, creating congestion at different points in the global transport infrastructure and increasing emissions of pollutants and greenhouse gases.

This report presents the results of a project conducted in 2006-07, aimed at improving global sourcing practices, with a particular emphasis on the implications for the UK. …

Distributed Cooperative Framework And Algorithms For Wireless Network Performance Optimization, Emily Hong Qi May 2007

Distributed Cooperative Framework And Algorithms For Wireless Network Performance Optimization, Emily Hong Qi

Dissertations and Theses

In Wireless Local Access Networks (WLANs), the Medium Access Control (MAC) protocol is the primary element that determines the efficiency of sharing the limited communication bandwidth of the wireless channel. IEEE 802.11 MAC uses the contention-based Distributed Coordination Function (DCF) as a fundamental medium access mechanism. However, the dynamic nature of the wireless environment creates mobility challenges of maintaining maximum channel capacity, of obtaining optimal throughput and latency, and of retaining good security in a distributed wireless network.

This dissertation first introduces a set of parameters to characterize the medium status and radio environment, and a mechanism for mobile devices …

Selected Chemistry Of Biologically-Active Thiols : N-Acetylpenicillamine And 2-Mercaptobenzothiazole In Nitrosothiol Formation And Role In Allergic Contact Dermatitis Respectively, Itai Chipinda

Dissertations and Theses

Two biologically-active thiols, N-acetylpenicillamine (NAP) and 2-mercaptobenzothiazole (MBT), were studied in this thesis. NAP is known to combine with nitric oxide (NO) to produce S-nitroso-N-acetylpenicillamine (SNAP) and MBT is a known allergen.

The formation, reaction dynamics, and detailed kinetics and mechanism of the reaction between nitrous acid (HNO2), prepared in situ, and NAP to produce SNAP were studied. The reaction is first order in nitrite, NAP and acid in pH conditions at or slightly higher than the pKa of HNO2. Both HPLC and quadrupole time-of-flight mass spectrometry techniques confirmed the formation of SNAP and the absence of any other products. …
