A Review of Current State Department of Transportation Practice for Promoting and Documenting the Safety of Field Employees

Creator:: Barlow, Zachary Wesley
Abstract:: State Departments of Transportation (DOTs) are the primary owners of roadway infrastructure in the United States. Many of the employees of state DOTs work on roadway work sites, putting them at disproportionately higher risks of injury or fatality. A review of the literature determined that a combination of policies, standards,...

Owner's Role in Brownfield Remediation : The Brownfield Experts' Perspective

Creator:: Saberiyan, Amireh G.
Abstract:: Former industrial or commercial sites that have been left unused are typically referred to as brownfield sites, or simply, brownfields. Many communities have such properties that are abandoned, idle or underused. Despite public efforts to facilitate brownfields revitalization projects, the rate of remediation remains unexpectedly slow. Efforts to resolve this...

Laboratory observations and numerical modeling of the effects of an array of wave energy converters

Creator:: Porter, Aaron K.
Abstract:: This thesis investigates the effects of wave energy converters (WECs) on water waves through the analysis of extensive laboratory experiments, as well as subsequent numerical simulations. Data for the analysis was collected during the WEC-Array Experiments performed at the O.H. Hinsdale Wave Research Laboratory at Oregon State University, under co-operation...

Wave field patterns generated by wave energy converters

Creator:: McNatt, J. Cameron
Abstract:: The eventual deployment of wave energy converters (WECs) on a commercial scale will necessitate the grouping of devices into arrays or "wave farms," in order to minimize overhead costs of mooring, maintenance, installation, and electrical cabling for shoreward power delivery. Closely spaced WECs will interact hydrodynamically through diffracted and radiated...

Driver Distraction from Unmanned Aerial Systems: Evidence, Policy, and Mitigation

Creator:: Barlow, Zachary W.
Abstract:: Unmanned aerial systems (UASs), more commonly known as drones, have recently achieved commercial success for many public and private applications. As with all emerging technologies, new safety concerns and conflicts with existing paradigms are likely to arise. Many potential applications of UASs will result in their operation near roadway infrastructure,...

Adjacent structure response sensitivity to seismic events using the direct differentiation method

Creator:: White, William S.
Abstract:: The response of adjacent structural systems to earthquake motions is investigated using the finite element framework OpenSees. Results of sensitivity analyses demonstrate that structural response quantities can increase in either or both of the adjacent structures for specific configurations. The structural models used include steel moment-resisting frames and rigid shear...

A socio-technical study on the improved characterization of stakeholder behaviors and stream temperature in design of watershed conservation practices for climate change adaptation

Creator:: Noa-Yarasca, Efrain
Abstract:: Characterizing stakeholder behavior when making decisions in watershed management is a great challenge for planners, not only because plans are associated with physical uncertainties but also because stakeholders’ behaviors are influenced by numerous factors. Since stakeholders’ decision-making is linked to multiple types of uncertainty, communication of uncertainty to stakeholders by...

Wind induced torsional fatigue behavior of truss bridge verticals

Creator:: Keller, Philipp
Abstract:: The Astoria-Megler Bridge is a 6.6 kilometer (4.1 mile) long bridge, connecting Oregon and Washington on US 101, with a continuous steel truss main span of 376 m (1232 ft). It is the second longest main span bridge of this type in the world. Due to vortex shedding, some of...

An Agent-Based Simulation for Emergency Warning Dissemination in a Multiplex Social Network

Creator:: Koll, Charles D.
Abstract:: The variety of natural disasters provide different sets of characteristics and properties with unique challenges. One significant difference between hazard types is prewarning lead time, the amount of time individuals have from a potential warning to the disaster occurring. Rapid onset disasters may not provide an official warning about a...

Multi-objective Optimization of Reservoir Operation Under Uncertainty with Robust and Flexible Decision Variables

Creator:: Hosseini, Parnian
Abstract:: Optimization of reservoir operation is involves various competing objectives for a scarce resource (water). To find the optimal operation of reservoirs, it is essential to consider multiple objectives simultaneously. There are various sources of uncertainty associated with the reservoir operation problem that should be considered as well. The overarching goal...
