Applying the Mixed Logit Model with Heterogeneity in Means and Variances to Pedestrian Injury Severity Outcomes

Creator:: Umphress, James
Abstract:: Walking is the single most universal mode of transportation in the world, but being a pedestrian exposes a traveler to high risk. Historically, pedestrians have consistently experienced disproportionately high rates of fatalities and severe injuries in traffic crashes. Research has probed into factors influencing pedestrian crash injury severity outcomes, but...

Durability and Performance of High Early Strength Concrete for Structural Bridge Deck Overlays

Creator:: Smith, Jeremy A.
Abstract:: High early strength concrete (HESC) allows for faster construction with less impact on traffic, thus reducing the indirect costs associated with a project. There are multiple methods for achieving early strength, such as alternative cements like calcium sulfoaluminate (CSA) or chemically accelerated portland cements. The standard criteria for an HESC...

A preliminary assessment of post-fire dissolved organic carbon concentrations in the McKenzie River basin, Oregon

Creator:: Hyatt, Charles
Abstract:: In recent decades, the occurrence of large, high severity wildfires has increased substantially in many parts of the world, including the western United States. These fires have the potential to impact water quality, aquatic ecosystems, and downstream communities for many decades. As such, it is increasingly important to understand the...

Hydrodynamic characterization of floating offshore wind turbines : an experimental and numerical multi-degree of freedom analysis

Creator:: Gadasi, Jonah B.
Abstract:: Wind energy has become a crucial resource in sustainably meeting increasing global energy demands. Recently, offshore wind energy has been gaining traction due to its higher gross resource and larger unclaimed real-estate relative to its onshore counterpart. Floating offshore wind turbines (FOWTs) are increasingly popular, particularly designs with semisubmersible platforms....

New Techniques to Monitor and Characterize Landslide Behavior and Controls Using Digital Terrain Models

Creator:: Senogles, Andrew
Abstract:: Coastal landslides and erosion are major natural hazards resulting in unstable slopes, constituting immense challenges to modern infrastructure. Developing, maintaining, and performing risk assessments of infrastructure on, or close to, these hazards require a detailed understanding of the geophysical processes destabilizing the slope. These efforts start with the collection of...

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...

Seismic Performance of Retrofitted Reinforced Concrete Columns Including Soil Structure Interaction

Creator:: Parson, Lance
Abstract:: There are many existing bridges around the world that were designed without consideration for seismic effects. Many of these bridges were designed before modern earthquake engineering design standards and practices existed and thus are expected to perform poorly during strong ground shaking. Common structural deficiencies are found in their reinforced...

Engineering Services of Submerged Aquatic Vegetation (SAV): Investigation of the Land-Building and Energy-Attenuating Properties of SAV Habitats Across Spatial Scales

Creator:: Holzenthal, Elizabeth R.
Abstract:: Submerged aquatic vegetation (SAV) species, such as seagrasses, are highly valued in estuaries because of the many economic, ecological, and cultural services that they provide, including shelter for fisheries, minimizing water turbidity, and improving am-bient water quality. SAV can also alter its physical environment by attenuating wave and current velocities,...

Experimental and Analytical Studies of Large-Scale Pile Caps

Creator:: Al-Sakin, Yasmeen
Abstract:: Pile caps are structural elements used to transfer loads from columns to a group of piles, which transfer them to stronger soil layers. Pile cap with horizontal distance between the column and piles less than twice its effective depth is categorized as "deep," where significant nonlinear strain distribution occurs through...

Perceived Effectiveness of Highway Work Zone Intrusion Mitigation Technologies: A State DOT Perspective

Creator:: Kadalli, Manjunath Veeresh
Abstract:: Highway work zones are extremely dangerous environments due to the presence of workers near high-speed traveling vehicles. This dynamic environment results in a disproportionate number of accidents that cause injury and casualty to both drivers and workers due primarily to vehicular intrusions into work zones. Several emerging work zone intrusion...
