Investigating The Bond Of Prestressing Strands In Lightweight Self-Consolidating Concrete, Royce Woodrow Floyd

Graduate Theses and Dissertations

Lightweight self-consolidating concrete (LWSCC) is a relatively recent advancement in concrete technology. The reduced dead load from lightweight concrete is beneficial for precast elements and for elements where dead load is a significant portion of the total load, such as prestressed bridge girders. Self-consolidating concrete (SCC) is a specially proportioned concrete mixture that consolidates under its own weight without the need for vibration. The combination of lightweight concrete and self-consolidating behavior provides the benefits of both. Bond of prestressing steel has been a much debated topic since the 1950s. Limited data are available on the transfer and development length of …

Inspired Living, Gongke Li

Graduate Theses and Dissertations

Inspired Living is a juxtaposition of old and new, contemplating the shift of values in contemporary China.

Patriotism used to be one of the key values in the Chinese people's minds, but those values have changed dramatically. Fewer people are thinking about or talking about patriotism, like sacrificing for the country or serving the people. In reality, getting rich and spending money to purchase all kinds of products, either absolute necessities or unnecessary luxuries, has become the key value of many Chinese people.

The images used in this project are all found and come from various sources, including books and …

Improved Protocols For Automated Wheelpath Crack Detection In Pavements, Daniel Patrick Byram

Graduate Theses and Dissertations

Roadway pavement distress evaluations are vital to understanding the mechanics of pavement stability, determining the distribution of rehabilitation costs, and knowing the appropriate rehabilitation strategies. Advancements in technology over the past two decades have changed the way these surveys have been performed by means of automated data collection and interpretation. More and more state agencies have invested in automated road analyzing vehicles that are able to collect high resolution images of the pavement. Fewer have adopted automated data processing software with the ability to interpret road distresses due to the common discrepancies in distress classification algorithms.

In addition to automated …

New Insights Into Disinfection Byproduct Formation And Control: Assessing Dissolved Organic Matter Diffusivity And Chemical Functionality, Ashley Pifer

Graduate Theses and Dissertations

Methods were developed for application of asymmetric flow field-flow fractionation (AF4) and fluorescence parallel factor (PARAFAC) analysis to raw and treated samples from drinking water sources to improve characterizations of dissolved organic matter (DOM) and discover DOM properties correlated to disinfection byproduct (DBP) formation potential (FP). Raw water samples were collected from a reservoir, adjusted to pH 6, 7, and 8 and subjected to (1) jar tests using aluminum sulfate (alum) and (2) treatment with magnetic ion exchange (MIEX^®) resin. Both treatments were followed by DBPFP tests at pH 7. AF4 was used to size DOM in raw …

Wheel Path Wandering Based On Field Data, Wenting Luo

Graduate Theses and Dissertations

The position and width of wheel path on a pavement lane is an important consideration in conducting pavement distress survey, especially for distinguishing longitudinal cracking from fatigue cracking. Currently, the widely used wheel path definition is derived from the LTPP distress manual with fixed width and position, in which the influence of traffic wander on wheel path was overlooked. This thesis attempts to develop a new wheel path definition based on the lateral placement investigation of heavy vehicles' wandering in the field. Generally, the factors influencing vehicle lateral placement can be divided into seven categories, but only four factors are …

The Trade And Welfare Impacts Of Australian Quarantine Policies: The Case Of Pigmeat, John C. Beghin, Mark Melatos

Department of Agricultural Economics: Faculty Publications

We analyze the trade and welfare impact of quarantine measures imposed by Australia on imports of pigmeat. In particular, we account for changes to Australia’s pigmeat quarantine policy over time, including those changes related to the recent resolution of a WTO dispute between Australia and the European Union. Using a random utility model and applying it to corner solutions in import decisions, tariff equivalents (by major trading partner) are estimated for the different pigmeat quarantine regimes implemented by Australia during the period 1988-2009. The welfare impact on consumers, producers, and foreign exporters is computed using a partial equilibrium model calibrated …

Key Findings Of The Ntm-Impact Project, David Orden, John Beghin, Guy Henry

Department of Agricultural Economics: Faculty Publications

This special issue of The World Economy presents research findings from the European Commission–funded project “Assessment of the impacts of non-tariff measures (NTM)—on the competitiveness of the EU and selected trade partners” (NTM-Impact). Directed toward the EU and its trade partners, the project’s first overall objective was to collect and analyze new data on NTMs for key and representative agri-food products. This involved three components: creating a large symmetric international database on the diverse types of governmental standards and regulations used to address food safety and quality issues, constructing measures of heterogeneity among these standards and regulations; and evaluating the …

Charles City Permeable Streetscape Phase I Landscape Performance Benefits Assessment, Bo Yang, Yue Zhang, Pamela Blackmore

Landscape Architecture and Environmental Planning Faculty Publications

The Charles City, Iowa, Green Street project addressed serious issues with street deterioration and nuisance street and adjacent yard flooding for a 16-block residential area. The project combines durable permeable paving materials with sustainable stormwater Best Management Practices, while maintaining the historical character of the neighborhood. By integrating stormwater management, the City was able to leverage additional funding that would not be available for conventional street reconstruction. Because of the success and the lessons learned in design and maintenance, the project has spurred additional phases in adjacent neighborhoods and serves as an important blueprint for others considering similar sustainable stormwater …

Cherry Creek North Improvements And Fillmore Plaza Landscape Performance Benefits Assessment, Bo Yang, Yue Zhang

Landscape Architecture and Environmental Planning Faculty Publications

The 16-block Cherry Creek North retail district was designed to be Denver's premier outdoor shopping area. Yet deteriorating infrastructure, tired aesthetics and competition from an adjacent indoor mall had led to steady decline. Fillmore Plaza in the heart of the district was no longer a desirable public space since being closed to vehicular traffic in 1987. The new streetscape strengthens the retail environment, preserves the district's history and character, improves identity, beautifies the area, provides new lighting, improves signage, and adds 20 "Art and Garden Places" for shoppers to relax and linger. The redesigned Fillmore Plaza is now a vibrant …

On The Cyclically Fully Commutative Elements Of Coxeter Groups, T. Boothby, J. Burket, M. Eichwald, D. C. Ernst, R. M. Green, Matthew Macauley

Publications

Let W be an arbitrary Coxeter group. If two elements have expressions that are cyclic shifts of each other (as words), then they are conjugate (as group elements) in W. We say that w is cyclically fully commutative (CFC) if every cyclic shift of any reduced expression for w is fully commutative (i.e., avoids long braid relations). These generalize Coxeter elements in that their reduced expressions can be described combinatorially by acyclic directed graphs, and cyclically shifting corresponds to source-to-sink conversions. In this paper, we explore the combinatorics of the CFC elements and enumerate them in all Coxeter groups. …

How To Define Mean, Variance, Etc., For Heavy-Tailed Distributions: A Fractal-Motivated Approach, Vladik Kreinovich, Olga Kosheleva

Departmental Technical Reports (CS)

In many practical situations, we encounter heavy-tailed distributions for which the variance -- and even sometimes the mean -- are infinite. We propose a fractal-motivated approach that enables us to gauge the mean and variance of such distributions.
