Eco-decision Making for Pavement Construction Projects.
(2013-02-25)Life cycle assessment (LCA) is a promising approach that can be used to quantify environmental impacts for selected products within defined system boundaries. Although LCA has begun to be applied to pavement systems, the ... -
Economic Characteristics of Drayage Drivers at the Port of Seattle
The Port of Seattle surveyed drayage truckers serving the port in 2006, 2008, and surveyed drivers again in 2013 in partnership with the University of Washington. This thesis describes the methodology used to survey drayage ... -
Economic Implications of the Use of Technology in Commercial Vehicle Operations
(2013-02-25)The effective and efficient movement of freight is essential to the economic well-being of our country but freight transport also adversely impacts our society by contributing to a large number of crashes, including those ... -
Ecophysiology of marine ammonia-oxidizing archaea
Ammonia oxidizing archaea (AOA) are one of the most abundant prokaryotes in the ocean and span diverse oceanic provinces. In addition to having a dominant role in marine nitrification, they are implicated as a major source ... -
Effect of Granular Sizes on Nutrient Removal and Recovery in wastewater treatment processes
High nitrogen and phosphorus loadings in wastewater treatment plant (WWTP) effluents are known to cause eutrophication damaging aquatic lives and habitats. However, many WWTP’s in the United States are not designed for ... -
Effect of Operational Parameters on Microgranular Adsorptive Filtration (μGAF)
Low-pressure membrane filtration has been used as a separation technique in water treatment applications for decades and is effective at removing particulates from water. However, it has limited ability to reject soluble ... -
Effects of Accelerated Curing on the Time-Dependent Properties of Concrete
The long-term creep and shrinkage behaviors of concrete can greatly affect the serviceability and constructability of prestressed concrete structures. To account for these effects, it is necessary to reliably predict the ... -
Effects of Auditory Alerts for Vehicle-to-Vehicle (V2V) Collision Warning Systems
Collision warning systems (CWSs) have shown great benefits in improving traffic safety by alerting drivers of potential collisions. However, some warning systems require information from nearby vehicles, which could be addressed ... -
Effects of Dissolved Organic Matter (DOM) on Metal Release from Solid Phases Typical for Corrosion Processes and Characterization of Interactions between DOM and Metal Cations by In Situ Spectroscopic Methods
This study examined impacts of dissolved organic matter (DOM) on copper release from copper solid model phases (tenorite and malachite) characteristic for copper corrosion in drinking water as well as characterizing ... -
Effects of Flow Shielding and Channeling on Tsunami-Induced Loading of Coastal Structures
Prior efforts to numerically model the complex fluid-structure interactions that occur as tsunami inundations pass through coastal communities have failed to consistently reproduce experimentally-measured flow velocities ... -
Effects of liquefaction-induced lateral spreading on pile foundations
(1996)Earthquakes cause structural damage in many ways. A particularly devastating combination occurs when pile foundations are situated in loose, saturated soil deposits that are prone to liquefaction. If such a deposit is ... -
EFFECTS OF LONG-DURATION GROUND MOTIONS ON LIQUEFACTION HAZARDS
Soil liquefaction during past earthquakes has caused extensive damage to buildings, bridges, dam, pipelines and other elements of infrastructure. Geotechnical engineers use empirical observations from earthquake case ... -
Effects of Projected Twenty-First Century Sea Level Rise, Storm Surge, and River Flooding on Water Levels in Puget Sound Floodplains and Estuaries
(2012-09-13)Near coastal environments have been identified as some of the most likely to be impacted by climate change. Observed changes in Puget Sound sea level and flood magnitudes are in line with those projected by previous climate ... -
Effects of Recent Concussion on Simulated Driving Performance in Young Drivers
The symptoms of a concussion include difficulties with balance, concentration, ocular-motor function and sensory integration. Concussions are common among young people given their exposure to sports and risky behavior. ... -
Effects of Roadway on Driver Stress: An On-Road Study using Physiological Measures
(2013-07-25)There has been a great deal of research expended on enhancing our roadway to ensure that road users are provided a smoother, more enjoyable ride. One area that has not been well examined is the relationship to safety and ... -
The Effects of Small-Scale Heterogeneity on the Large-Scale Dynamics of West Siberian Wetland Carbon Fluxes
(2013-07-25)Wetlands are the world's largest natural source of methane and an historically large sink of atmospheric carbon. High-latitude wetlands have received increasing scrutiny recently, due to the temperature sensitivity of ... -
Effects of spatial constraints on channel network topology: implications for geomorphological inference
(1997)In the fifty-two years since Robert Horton's 1945 pioneering quantitative description of channel network planform (or plan view morphology), no conclusive findings have been presented that permit inference of geomorphological ... -
Effects of Using Virtual Reality on AEC Team Collaboration
Construction projects require coordination of different disciplines, which makes knowledge management and information exchange crucial in design and construction teams. Building Information Modeling (BIM) is a powerful ... -
Effects of Water Quality Changes on the Corrosion of Iron, Accumulation and Release of Inorganic Contaminants in Drinking Water Distribution Systems
(2012-08-10)Corrosion and accumulation/release of trace inorganic contaminants in corrosion scales and sediments found in drinking water distribution systems (DWDSs) has gained considerable attention over the past several years. Many ... -
Efficient and Robust Machine Learning Methods for Challenging Traffic Video Sensing Applications
The development of economics and technologies has promoted urbanization worldwide. Urbanization has brought great convenience to daily life. The fast construction of transportation facilities provides various means of ...
