CO₂ trapping mechanisms assessment using numerical and analytical methods
(2020-01-30)
Carbon capture and storage (CCS) is a proven technique for reducing greenhouse gas emissions and climate change. Although monitoring shows that CO₂ can be safely stored underground, CO₂ leakage is still of concern. Therefore, ...
Adapting housing and water sector infrastructure to population dynamics
(2020-01-29)
In a world increasingly urban and subject to large and sudden population displacements—resulting from factors such as political instabilities, urban mobility, or disasters—understanding interdependencies between infrastructure ...
Towards practical models of Continental River Dynamics with the Saint-Venant equations
(2020-08-10)
Simulating dynamic river networks at continental scales has been a long-term goal of the hydraulic and hydrologic communities. However, difficulties in computational costs, data availability, and numerical stability have ...
Characterizing emerging urban transportation modes : models and methods
(2020-12-07)
The introduction of emerging transportation technologies, such as mobility-on-demand and shared modes, have caused disruptions in urban transportation systems. These services brought multiple challenges, including the lack ...
Shared autonomous vehicle system designs for major metro areas : an examination of geofencing, ride-sharing, stop-location, and drivetrain decisions
(2020-12-04)
With autonomous vehicles (AVs) in the testing phase, researchers and planners must resort to simulation techniques to explore possible futures regarding shared and automated mobility. An agent-based discrete-event transport ...
Lift axles in ready mix trucking
(2020-04-20)
Lift axles on single-unit commercial vehicles, referred to as Specialized Hauling Vehicles (SHVs) are being used today by various industries, allowing for heavier truck loads and compliance with state / federal laws. Certain ...
Machine-learning-based models, methods, and software for intensity, vulnerability, and risk assessment of Central U.S. induced earthquakes
(2020-08-14)
Since 2009, the Central U.S. has been subjected to a new type of seismic hazard attributed to human activities from the petroleum industry. Since then, there has been an increase in the number of earthquakes in the Central ...
Rapid and cost-effective approach to evaluate the effectiveness of wastewater and treatment byproduct solidification
(2020-05-15)
Wastewater and treatment byproducts from fossil fuel extraction (produced waters from oil and gas extraction) and combustion (flue gas desulfurization brines from coal power generation facilities) contain metals that can ...
Sources of variability in small-scale soil-geosynthetic interaction testing
(2020-08-13)
Lateral restraint is the primary mechanism associated with geosynthetic-stabilized road bases. Under traffic loading, the unbound aggregates tend to displace laterally unless they are restrained by the subgrade or by ...
Understanding traffic disruptions caused by communication network failures through survey and simulation
(2020-05-15)
Smartphone navigation applications providing real-time traffic information have become increasingly popular among drivers. Research showed that drivers' cognitive abilities for spatial navigation would deteriorate with ...
