A Decision-Framework for Building Portfolios Towards Enhanced Resilience and Sustainability of Communities Under Natural Hazards
(2019-05-10)
In recent years, communities in the U.S. and other countries have experienced several catastrophic natural hazards (e.g. Hurricane Katrina in 2005 and the Christchurch Earthquake in 2011). The unproportioned social, ...
Synthesis and Characterization of Porous Hydroxyapatite Ceramics for Batch and Column Treatment of Fluoride-Impacted Ground Water
(2019-05-10)
Nearly 200 million people worldwide are exposed to drinking water with elevated levels of naturally occurring fluoride. The World Health Organization recommends a maximum fluoride concentration of 1.5 mg/L in drinking water ...
Design and Assessment of Innovative Dual-Mode Rolling Isolation Systems
(2019-08)
Loss of operation or devastating damage to buildings and industrial structures, as well as equipment housed in them, has been observed due to earthquake-induced vibrations. A common source of operational downtime is due ...
The Effects of Evaporation and Capillary Forces on Fluid Motion, Solute Transport, and Water Content From the Grain Scale to the Continuum Scale in Unsaturated Porous Media
(2019)
This work aimed to explore how fluid motion, solute transport, and water content are influenced by evaporation and capillary forces in unsaturated porous media, across a range of scales. Experiments were conducted from the ...
Exploring the Relationship Between Grain Configuration and the Movement Of Capillary-Held Water in Unsaturated Porous Media
(2019)
The air-water interface in porous media has been studied for decades, and is important for understanding the distribution and movement of water, solutes and suspended colloids and nanoparticles in the unsaturated zone. The ...
Characterization of Rutting in Asphalt Pavements using Laboratory Testing
(2019)
In asphalt pavements, rutting is one of the main concerns at high in-service temperature, which can occur either through plastic flow or shear in structural layers. Rutting depends on several factors, such as asphalt binder ...
