Radar and Optical Remote Sensing of Submesoscale Frontal Features

Creator:: Simpson, Alexandra J.
Abstract:: The coastal region is home to many types of surface fronts that exist on a submesoscale (1-10 $km$). While in situ observations capture point or transect observations of frontal behavior subsurface, their complex spatial patterns can be well-captured using remote sensing techniques, which provide synoptic views of the ocean surface...

Quantifying the Relative Role of the Key Drivers of Coastal Dune Evolution: Observations and Simulations Across a Range of Time and Space Scales in Cape Lookout National Seashore, North Carolina

Creator:: Hovenga, Paige A.
Abstract:: Coastal dunes provide a diverse set of ecosystem services including coastal protection against destructive surge and waves during storm events. Dunes are constantly evolving through various stages of response to storm events and post-storm recovery at rates that vary due to a range of drivers including pre-existing morphology, environmental forcing...

A Multivariate Comparison of Drone-Based Structure from Motion and Drone-Based Lidar for Dense Topographic Mapping Applications

Creator:: Simpson, Chase H.
Abstract:: Unmanned aircraft systems (UAS), also known as drones, are an increasingly popular method of collecting surveying and mapping data. Two common drone-based mapping techniques are lidar and structure from motion (SfM) photogrammetry, and a frequently-heard (yet nearly impossible to answer) question is: “which is better?” The most common metric for...

Effects of soil slope on lateral capacity of piles in cohesive soils

Creator:: Nimityongskul, Nontapat
Abstract:: Pile supported bridges are typically constructed near or in a natural or man-made slope and are subjected to lateral loading. The current design method for laterally loaded piles involves the use of Winkler's spring concept with the standard nonlinear p-y curves. The available p-y curves were developed based on results...

Assessing the Trade-Off Between Sustainability and Resiliency of Reinforced Concrete Alternatives in Corrosive Conditions: An LCA-System Dynamics Approach

Creator:: Moreno Rangel, Erick D.
Abstract:: Concrete has been categorized as a key contributor of CO2 (carbon) emissions into the atmosphere. This is mostly associated with the production of ordinary portland cement (OPC). The concrete and cement industries are pursuing a path to reduce their carbon emissions generally in accordance with the climate change goals outlined...

The Number of Lanes and Crash Injury Severities of Commercial Motor Vehicle Drivers: Advanced Econometric Models and Applications

Creator:: Kim, Jaekook
Abstract:: Considering the deadly impacts of commercial motor vehicle (CMV) crashes on road safety, many previous studies have put in efforts to find the determinants of CMV crash injury severities. However, studies examining the impact of the different number of lanes on CMV crash injury severities are lacking. Besides, the importance...

Multi-Criteria Risk Mapping Using Lean Tools for the Architecture, Engineering, and Construction Industry

Creator:: Viriato Maia Ferreira Pestana, Ana Catarina
Abstract:: Over the past two decades, the Lean Construction academic and practicing engineering community has used lean practices and tools to help improve the performance of the Architecture, Engineering, and Construction (AEC) industry. Lean practices have led to improved competitiveness of construction companies that have adopted them, by focusing on ways...

Regional and Site-Specific Vulnerabilities of the Western Power Grid from a M9.3 Cascadia Subduction Zone Earthquake

Creator:: Lathrop Eve D.
Abstract:: The likelihood of a Cascadia Subduction Zone (CSZ) earthquake is estimated between 37 to 42% in the next 50 years, leading to strong shaking, liquefaction, landsliding, and other seismic ground failure resulting in major impacts to critical lifelines such as the western power grid. Electrical power is essential for continued...

Safety performance of curve advisory speed signs

Creator:: Avelar Moran, Raúl Eduardo
Abstract:: Posting advisory speed signs at sharp horizontal curve sites is a practice well established in the United States. The purpose of these signs is to provide the driving public with a safe speed to negotiate such curves; however, the link between these signs and safety has not yet been clearly...

Blast-induced liquefaction : observational estimation of vibration, settlement and residual pore water pressure

Creator:: Kato, Kengo
Abstract:: The blast technique has been used as an effective soil improvement method to compact loose coarse-granular soils since 1930s, and the use of the blast technique is extended as an application of in-situ liquefaction testing to investigate the performance of full scale foundations and countermeasures against liquefaction in recent decades....
