Bend-Twist Coupled Carbon-Fiber Laminate Beams: Fundamental Behavior and Applications
Material-induced bend-twist coupling in laminated composite beams has seen applications in engineered structures for decades, ranging from airplane wings to turbine blades. Symmetric, unbalanced, carbon fiber laminates ... -
Better understanding human impacts on river thermal regimes under climate change
Human activities, especially dam construction, greatly modify the response of river thermal regimes to climate change. Dams impound large water bodies, decrease surface to volume ratios, and increase water residence times. ... -
Bi-level Optimization Algorithm for Dynamic Reversible Lane Control based on Short-term Traffic Flow Prediction
Traffic congestion is a more and more serious problem all over the world. Reversible lanes have been used throughout the world to mitigate the effects of congestion and optimize roadway performance for more than 80 years. ... -
Bioaugmentation with Sidestream Granular Sludge for Nitrification in Activated Sludge Wastewater Treatment: Pilot-Scale Investigation
Stricter effluent permits and growing metropolitan areas have contributed to a move towards the intensification of biological treatment processes for water resource recovery facilities (WRRFs). Process intensification with ... -
Biocementation for Liquefaction Mitigation: Examining Response, Development, and Deployment
Microbially Induced Calcite Precipitation (MICP) is an environmentally conscious soil improvement technique that can improve the geotechnical properties of granular soils through the precipitation of CaCO3 minerals on soil ... -
Breaking Waves on the Ocean Surface
In the open ocean, breaking waves are a critical mechanism for the transfer of energy, momentum, and mass between the atmosphere and the ocean. Despite much study, fundamental questions about wave breaking, such as what ... -
CFD Modeling of an Oscillating Wave Surge Converter using the Overset Grid Method
In recent decades, the push for reliable renewable energy sources has led researchers to explore an ever-expanding array of novel devices capable of harvesting such energy. Of the current available renewable energy sources, ... -
CFT Column-to-Cap Beam Connections for Accelerated Bridge Construction in Seismic Regions
Due to their increased mechanical properties and ease of construction, Concrete filled steel tubes (CFTs) offer an efficient and economical alternative compared to traditional reinforced concrete columns. Despite their ... -
Characterization of Beam Vibration
A beam is one of the most fundamental elements in structural engineering, mechanical engineering, and aerospace engineering. Moreover, complex structures like large flexible solar arrays, airplane wings, high-rise buildings, ... -
Characterization of Marine Mammal Biomechanics to Evaluate Tidal Turbine Collision Impact
Tidal energy has an immense potential for creating renewable energy from the ocean's moving tides and is under investigation worldwide. In this emerging field, potential environmental consequences of installing tidal ... -
Characterization of Performance Predictors and Evaluation of Mowing Practices in Biofiltration Swales
(2000)General site maintenance is important for keeping a well functioning swale; however, it is not always easy to determine how well a site is currently functioning. Swale performance can be evaluated by measuring its hydraulic ... -
Characterizing Lowland Streams: Riparian and Watershed Influences on Urban and Non-Urban Channels
(University of Washington, 2003)This thesis presents a suite of studies focused on the channel network of the Chico Creek watershed, a resource-rich stream system on the Kitsap Peninsula in western Washington State. This analysis included characterization ... -
Characterizing the urban freight system and the supporting infrastructure network
The urban freight system is essential to today's economy and cities' livability. In the last decade, densification, the growth of e-commerce, and the changing mobility ecosystem have amplified commercial vehicles' challenges ... -
Characterizing Water Quality of Urban Stormwater Runoff: Interactions of Heavy Metals and Solids in Seattle Residential Catchments
(University of Washington, 2004)Stormwater quality and quantity were investigated in urbanized catchments in the Pipers Creek watershed in North Seattle in order to characterize existing rates and processes of stormwater runoff in areas of moderate-density ... -
Combining Indirect Observations and Models to Resolve Spatiotemporal Patterns of Precipitation in Complex Terrain
Mountain precipitation in the Western United States is critical for the water resources of the region, but resolving spatial and temporal patterns of precipitation in complex terrain is challenging due to lack of observations, ... -
Combining multiple observations to improve our understanding of forest-snow interactions and inform forest management
Many regions of the world rely on snowmelt from seasonal snowpacks for water resources. In the Northern Hemisphere, half of the seasonal snow zone overlaps with forests which interact with both snowfall and snow on the ... -
Combining PAC and HAOPs with Microgranular Adsorptive Filtration to Enhance Water Treatment
Immense effort has been made over the past few decades to address the challenge of sustainable drinking water production. As a result of this endeavor, low- and high-pressure membrane filtration have been developed as a ... -
COMMUTING SERVICE PLATFORM: CONCEPT, METHOD, AND ANALYSIS
Commuting congestion increases alongside the prosperity of urban cities. With the rapid development of ridesourcing services and the advances of connected and automated vehicles (CAV), researchers are seeking innovative ... -
Comparison of Effects of Bromination and Iodination on the Spectroscopic Properties of Natural Organic Matter
(2013-07-25)Toxicological studies of disinfection by-products (DBPs) suggest that brominated and iodinated DBPs may be more carcinogenic than their chlorinated analogues. This makes it important to examine the pathways of formation ...
