Power Output Calculations for an Array of Point-absorber Wave Energy Converters

Creator:: García-Castaño, Manuel
Abstract:: This study presents a methodology for power take off (PTO) forecasting for an array of heave wave energy converters (WECs). Based on spectral data obtained directly from the National Data Buoy Center, representative realistic sea states are generated at the location of the WECs, and by using two wave-structure interaction...

Characterization of the Small-Strain Stiffness of Soils at an In-situ Liquefaction Test Site

Creator:: Donaldson, Aleyna M.
Abstract:: Strong ground motions from earthquakes can result in the reduction of the shear modulus and wave propagation characteristics of soils, and can produce liquefaction and cyclic softening during shaking and for some time following the seismic event. While the ground motions produced from controlled blasting are different than those in...

Normal acceleration characteristics of the leading vehicle in a queue at signalized intersections on arterial streets

Creator:: Zhu, Hong
Abstract:: Normal acceleration characteristics of passenger cars provide valuable information for various aspects of transportation engineering, including use in the geometric designs of intersections, freeway ramps, passing lanes, acceleration lanes, turning bays, or in the development of traffic simulation or fuel consumption models. However, the data used in previous studies are...

Wave runup : Physics, variability, and societal impacts

Creator:: García Medina, Gabriel
Abstract:: The U.S. Pacific Northwest is home to one of the most extreme wave climates in the world with waves of 10 m in height arriving to the coast approximately each year. With an average water temperature of 12℃, the beaches in the region are too cold to go on a...

The Art of Reducing Coastal Hazard Complexity: Coupling Physics and Probability to Understand Extremes, Variability, and Climate-dependence

Creator:: Anderson, Dylan L.
Abstract:: Coastal hazards are the result of numerous physical processes cumulatively causing water levels to flood and erode the land. The waves, storm surges, tides, and run-off contributing to elevated water levels are each the product of chaotic and random weather patterns. These stochastic weather patterns dissipate energy in Earth's climate...

Enhancing Detection of Marine Debris with Polarimetric Imagery

Creator:: Herrera, Frederick Kyle
Abstract:: Marine debris is a chronic and increasingly pervasive problem for coastal regions around the world. Debris poses environmental risks, threats to wildlife, and degradation of the natural environment. Recent research has shown the advantages of uncrewed aircraft systems (UAS) for detection and recognition of marine debris, including the ability to...

Experimental and analytical evaluation of conventionally reinforced deck-girder bridge bent caps with vintage details

Creator:: Senturk, Ahmet Ekin
Abstract:: Many conventionally reinforced concrete deck girder (RCDG) bridges were built in the US during the 1950s, throughout the expansion of the Interstate System. Designs followed the AASHO standard of the time, which permitted higher shear stress in concrete and reduced detailing requirements than permitted by current specifications. Many of these...

An Efficient Point Cloud Processing Framework for Terrestrial and Mobile Lidar Data via Reconstructing the Scan Pattern Grid

Creator:: Che, Erzhuo
Abstract:: Lidar (LIght Detection And Ranging) is a remote sensing technology using light in the form of a pulsed laser, which enables efficient, accurate, 3-D data acquisition of a scene. Depending on the mounting platform, lidar data acquisition can be categorized into Airborne Laser Scanning (ALS, or airborne lidar), Terrestrial Laser...

Application of Technologies for Temporary Structures during the Design and Construction Phases

Creator:: Jin, Ziyu
Abstract:: The development of technologies such as Building Information Modeling (BIM), light detection and ranging (lidar), and sensor-based systems poses new opportunities for researchers to rethink how construction safety and health can be approached during the design, planning, and construction phases of a project. Nevertheless, the majority of the technology applications...

Small Unmanned Aircraft Systems (UAS) for Engineering Inspections and Geospatial Mapping

Creator:: Javadnejad, Farid
Abstract:: Small unmanned aircraft systems (UAS) carrying consumer-grade nonmetric cameras are increasingly utilized to generate high-resolution 3D geospatial data. Low cost, ease of operation, widespread availability and low altitude maneuvering capabilities of UAS, as well as the rapid development of technology and methods, make UAS-based photogrammetry applicable to many civil engineering...
