Treatment of activated sludge process effluent by carbon adsorption

Creator:: Davis, Stewart Lee
Abstract:: An evaluation of the service time of an activated carbon adsorption column and the organic carbon removal efficiency treating activated sludge process effluent was completed at aerator detention times of three, five, and ten hours. Parameters used for evaluation of treatment were biochemical oxygen demand, chemical oxygen demand, total organic...

In-plane Creep Behavior of Cross-laminated Timber and Mass Plywood Panels: A Methodology to Evaluate the Long-term Performance of Post-Tensioned Mass Timber Walls

Creator:: Longman, Ryan P.
Abstract:: Post-tensioned (PT) self-centering shear walls were designed to reduce structural damage from seismic activity. However, these lateral force resistant systems experience post-tension loss negatively affecting the re-centering capability due to delayed deformations experienced by engineered wood products over time. The long-term mechanical response of mass-timber panels to in-plane PT loads...

Hybridized framing to modify load paths and enhance wood shearwall performance

Creator:: Bultena, Sarah M.
Abstract:: Heavy timber framing relies primarily on bracing to withstand lateral loads due to earthquakes and wind events. Bracing configurations in heavy timber framed buildings vary widely and include cross bracing, knee bracing, and other geometries. Many heavy timber frames constructed during colonial American times are still standing, exceeding the expected...

Evaluation of straw wattle placement and surficial slope stability

Creator:: Rikli, Anthony M.
Abstract:: Straw wattles are common erosion control devices used to trap sediment. This thesis studies the relationship of straw wattles on slope stability through a case study demonstrating their use on steep slopes (1.5H:1V) for the US20 highway realignment project. Several surficial slope failures have occurred on these fill slopes, often...

An evaluation of gap acceptance behavior at unsignalized intersections

Creator:: Nabaee, Sahar
Abstract:: Gap acceptance behavior is critical to the safety and operational performance of unsignalized intersections. The complex nature of the human behavior and its dependence on various socioeconomic and environmental parameters makes it challenging for transportation professionals to assess the performance of such intersections. To investigate the behavioral patterns of drivers...

Effectiveness of curve advisory speed signs : a characterization of road operations in western Oregon

Creator:: Avelar Morán, Raúl Eduardo
Abstract:: Posting advisory speed signs at sharp horizontal curve locations is a common practice in the U.S. These signs recommend drivers safe speeds to negotiate such curves. Literature indicates that adherence to advisory speeds is, in general, poor. Moreover, limited research is available that quantifies safety implications of these signs. This...

An Efficient Workflow and Accuracy Assessment for ICESat-2 and Multispectral Imagery Fusion for Bathymetric Mapping

Creator:: Babbel, Benjamin J.
Abstract:: Interest in mapping bathymetry from multispectral satellite imagery has grown steadily since the 1970s. Notwithstanding the significant advancements made during this time, one limitation is that the group of algorithms collectively referred to as Satellite Derived Bathymetry (SDB) generally require “seed depths,” hindering their use for areas lacking reliable reference...

Evaluation of Stereoscopic Camera Systems for Non-Intrusive Spatial Free Surface Measurement in Coastal Research Laboratories

Creator:: O'Day, Christopher S.
Abstract:: Physical modelling is instrumental to the progression of coastal engineering research and our understanding of the offshore and nearshore environments. Scaled models are designed and built to be tested in coastal research laboratories, where a wave basin or flume generates the desired wave conditions for experimentation. The surrounding hydrodynamics of...

Oregon coastal lake study : phosphorus loading and water quality implications

Creator:: Blair, Michael Stuart
Abstract:: A study of phosphorus loading and water quality implications was conducted for the Oregon coastal lakes. The study was based on existing data for lake total phosphorus concentrations and for watershed land uses. A phosphorus mass-balance model was developed to predict lake total phosphorus concentrations from estimated phosphorus loading from...
