  • Hinged floating breakwater : theory and experiments

    Creator:
    Leach, Patrick A.
    Abstract:
    An analytical model is developed to examine the response and efficiency of a vertical rigid, hinged, floating breakwater. The boundary value problem describing the flow field yields a well-posed Sturm-Liouville problem which is solved by separation of variables for the velocity potentials. The equation of breakwater motion about the breakwater...

  • Design and evaluation of a foundation model testing device

    Creator:
    Kelly, Patrick Bryan
    Abstract:
    Model testing has proven to be an effective tool in the study of soil-structure systems. While primarily used in research work, this method of evaluation is also applicable to the solution of many types of complex design problems. Because of its workability and relatively simple characteristics, sand is the most...

  • Visual Search Patterns and Behavior of Left Turning Bicyclists at Roadway Intersections: A Field Study

    Creator:
    Burns, Patrick O.
    Abstract:
    This research effort considers bicyclist’s left-turn behavior at roadway intersections with varying levels of traffic control; specifically, seeking to address the question where do bicyclists look to acquire information. A demographic comparison was made to determine if factors such as gender or experience influence the nature of how a bicyclist...

  • The effect of elevated pressure on the activated sludge process

    Creator:
    Godsil, Patrick James
    Abstract:
    A study of the effect of elevated pressure on the activated sludge waste treatment process is presented. The method of study involved a comparison of two laboratory, batch type, activated sludge units. One unit was operated at atmospheric pressure as a base control and the other operated at elevated pressures...

  • Implications of distracted driving on driver behavior in the standing queue of dual left-turn lanes : an empirical study

    Creator:
    Marnell, Patrick Stanley
    Abstract:
    Driver distraction is a commonly observable phenomenon with a significant effect on the transportation network. Although the negative effects of driver distraction on safety are commonly studied, there has been little effort made to investigate the impacts of distraction on efficiency. This study will examine driver behavior in standing queues...

  • Multi-hazard Damage and Loss Assessment of Bridge Networks

    Creator:
    Burns, Patrick O.
    Abstract:
    The overarching objective of this study is to examine and compare the vulnerabilities of bridges combining effects of earthquake-induced ground shaking, ground failure (e.g., landslides and lateral spreading), and tsunami inundation. A parametric study is performed to understand the sensitivity of economic loss and traffic capacity with respect to the...

  • Analysis of thermal fatigue distress of asphalt concrete pavements

    Creator:
    Jackson, N. Mike (Nathaniel Michael)
    Abstract:
    Thermal cracking of asphalt concrete pavements is responsible for millions of dollars in annual maintenance and rehabilitation costs in the United States and Canada. Thermal cracking is typically associated with low temperatures in northern climates and at high elevations. However, another form of thermal cracking, known as thermal fatigue cracking,...

  • Assessing durability of reinforced concrete and ductile iron

    Creator:
    Shields, Silas A.
    Abstract:
    The first goal of this master’s thesis was to investigate the linkage between a non-destructive testing method, surface resistivity, and premature concrete deterioration brought on by chloride ingress and or freeze-thaw cycling. The experimental method for this project consists of taking surface resistivity measurements of reinforced concrete slabs after they...

  • Experimental design of physical aquifer models for evaluation of groundwater remediation strategies

    Creator:
    Humphrey, Mark D.
    Abstract:
    Groundwater resources have become seriously threatened due to improper use by industrial, municipal, and even public sectors. Widespread contamination of aquifer systems has jeopardized human health and the environment and methods for restoring these systems are needed. Biological and chemical in situ remediation, where contaminants are degraded within the natural...

  • Understanding the Similarities and Differences Between Academia and the Engineering Workplace through Barriers to Adoption, Epistemic Beliefs, and Problem-Solving Behavior

    Creator:
    Gestson, Sean Lyle
    Abstract:
    Engineering education research has led to a greater understanding of the gap in preparedness of students for the engineering industry. Multiple studies comparing the workplace and academic contexts and the participants in those contexts (i.e., students, faculty, and engineering practitioners) have emphasized similarities and differences between the two contexts by...
