Environmental Durability Of Reinforced Concrete Deck Girders Strengthened For Shear With Surface Bonded Carbon Fiber-Reinforced Polymer, Christopher Higgins, Matthew R. Dawson, Mikal M. Mitchell, Gautam Sopal, A. Ekin Senturk

TREC Final Reports

This research investigated the durability of carbon fiber-reinforced polymer composites (CFRP) used for shear strengthening reinforced concrete deck girders. Large beams were used to avoid accounting for size effects in the data analysis. The effort included determining the role of freeze-thaw, moisture, and fatigue on structural performance and developing analytical design procedures that account for durability.

The results showed that moisture infiltration behind the CFRP, combined with freeze-thaw, was critical in reducing shear panel stiffness and shear capacity. Long-term moisture exposure alone produced only a minor decrease in shear capacity. Freeze-thaw, combined with fatigue, had little effect on shear capacity …

Civil and Environmental Engineering Faculty Publications and Presentations

This paper studies approximations to the average length of Vehicle Routing Problems (VRP). The approximations are valuable for strategic and planning analysis of transportation and logistics problems. The research focus is on VRP with varying number of customers, demands, and locations. This modeling environment can be used in transport and logistics models that deal with a distribution center serving an area with daily variations in the demand. The routes are calculated daily based on what freight is available. New approximations and experimental settings are introduced. Average distance travelled is estimated as a function of the number of customers served and …

Improving Travel Information Products Via Robust Estimation Techniques, David Maier, Kristin A. Tufte, Rafael J. Fernández Moctezuma

TREC Final Reports

Traffic-monitoring systems, such as those using loop detectors, are prone to coverage gaps, arising from sensor noise, processing errors and transmission problems. Such gaps adversely affect the accuracy of Advanced Traveler Information Systems. This project will explore models based on historical data that can provide estimates to fill such gaps. We build on an initial study by Mr. Rafael J. Fernandez-Moctezuma, using both a linear model and an artificial neural network (ANN) trained on historical data to estimate values for reporting gaps. These initial models were 80% and 89% accurate, respectively, in estimating the correct speed range, and misclassifications were …

Measuring The Effects Of Food Carbon Footprint Training On Consumer Knowledge, Transfer Intentions, And Environmental Self-Efficacy, Wayne Wakeland, Lindsay Sears, Kumar Venkat

Complex Systems Faculty Publications and Presentations

The supply chains through which foods are produced, processed, and transported can have a significant impact on the environment in terms of the carbon dioxide (CO2) that is emitted during each of these phases; however, little research has incorporated information about environmental impact into supply chain scenarios. Moreover, many consumers are unaware of how their food choices may impact the environment in this way. To fill these gaps, a tool called CarbonScope was developed to show consumers the CO2 emissions associated with different food types and food transportation scenarios. A short training was designed that walks participants through various food …

The Social Bottom Line Of Community Development Financial Institutions: What Facilitates Or Inhibits The Uptake And Use Of Meaningful Social And Community Impact Reporting?, Kelly Haines

Dissertations and Theses

Businesses, governments and communities are increasingly interested in measuring the non-financial impacts of their activities and investments. This assessment often takes the form of measurement models that utilize a Triple Bottom Line (TBL) framework, namely looking at the areas ofthe environment, the economy, and the social simultaneously. Despite its many accounting flaws, more and more organizations adopt this philosophy by applying it literally in the form of impact reports. In this framework, the social dimension is the most challenging to measure. Because of its complexities, this aspect of TBL reporting has often been vague and lack rigor.

The research question …

As the methodology used is qualitative, utilizing textual analysis to conduct a case study, academic journals from the fields of conflict resolution, sociology, political science, public health, cultural studies and economics were relied upon for the most part. This study of structural violence …

“In The Shadow Of A Concrete Forest”: Transportation Politics In Portland, Oregon, And The Revolt Against The Mount Hood Freeway, 1955-1976, Val C. Ballestrem

Dissertations and Theses

In 1955, The Oregon State Highway Department helped usher in the freeway building era in Portland by publishing its plan for 14 modern freeways designed to crisscross the city. A major component of that report was the Mount Hood Freeway, a route designed to pass through southeast Portland, connecting the city to its expanding eastern suburbs. Other freeway routes in the Portland area were given precedence over the Mount Hood Freeway and by 1969, when the route obtained federal interstate status, urban freeways across the nation had become highly controversial. Over the next seven years a struggle ensued pitting those …

The Institutionalization Of Diversity And Gender Equity Norms And Values In Higher Education Settings, Rowanna Lynn Carpenter

Dissertations and Theses

Universities in the United States increasingly experience demographic, business, and community pressure to hire, retain, and educate women and ethnic minority faculty, staff, and students. Responses to this pressure have changed over time from isolated open-door initiatives to comprehensive diversity initiatives designed to create welcoming campus environments for people of all backgrounds. Current literature on the assessment of diversity initiatives in higher education suggests the need to use approaches that include attention to the entire university, and to institutionalize the norms and values associated with diversity initiatives as part of the change process. Despite this shift toward a comprehensive understanding …

Challenging The New Penology: A Case-Study Analysis Of Correctional Management, Interstate Inmate Transfers, And Administrative Intent, Robert Thomas Swan

Dissertations and Theses

The purpose of this study is to explore the use of interstate inmate transfers (IITs) by prison wardens and the administrative intent that guide their use. This study assesses the explanatory power of the new penology in three cases and asks three broad questions of two prison wardens and the DOC: What correctional goals do you hope to accomplish with interstate inmate transfers? Why? And what contextual factors (if any) are felt to inhibit or facilitate these goals?

IITs are controversial. Supporters of IITs argue that in addition to serving the needs of correctional managers, they may also serve to …
