Combining Geostatistical Analysis and Flow-and-Transport Models to Improve Groundwater Contaminant Plume Estimation.
(2009)
Groundwater is an important resource, which is often contaminated. In order to ensure a sustainable supply, groundwater has to be monitored, contaminant plumes must be estimated accurately, and remediation operations must ...
A Macro-scale Plasticity Model for High Performance Fiber Reinforced Cement Composites.
(2009)
A macro-scale plasticity model for High Performance Fiber Reinforced Cement Composites (HPFRCC) is developed. The proposed model is a phenomenological, multi-axial, constitutive model capable of representing important ...
Engineering Characterization of Earthquake Ground Motions.
(2009)
In recent years, geologic and paleoseismic evidence has raised the awareness about the seismic hazard of the stable continental region of central-eastern U.S. (CEUS). The relevance of this topic increased due to the Nation’s ...
Density Functional Theory Studies on the Relative Reactivity of Chloroethenes on Zerovalent Iron.
(2008)
This study investigated the adsorption and dissociation of perchloroethene (PCE), trichloroethene (TCE), and cis-dichloroethene (cis-DCE) on zerovalent iron. The mechanisms by which iron decomposes chlorinated solvents by ...
ARVISCOPE: Georeferenced Visualization of Dynamic Construction Processes in Three-Dimensional Outdoor Augmented Reality.
(2008)
Construction processes can be conceived as systems of discrete, interdependent activities. Discrete Event Simulation (DES) has thus evolved as an effective tool to model operations that compete over available resources ...
Chemical Optimization of In Situ Emplacement of Nano-Particulate Iron Sulfide in Porous Media.
(2009)
Chemical optimization of an alternative construction method for permeable reactive barriers (PRBs) was investigated. Conventional trench-and-fill construction methods of PRBs are limited to shallow and thin aquifers, and ...
Adapting Land Use and Infrastructure for Automated Driving: Part A
(2024-01-05)
Automated vehicles (AVs) will likely yield a transformation of urban form, its land use and
mobility system. This report is concerned with adapting land use and transportation
infrastructure for automated driving. In the ...
Predicting Driver Takeover Performance in Conditional Automation (Level 3) through Physiological Sensing
(2024-01-05)
The National Highway Traffic Safety Administration (NHTSA) calls for fundamental research on “the driver performance profile over time in sustained and short-cycle automation … and driver-vehicle interface to allow safe ...
Improving the Efficiency of Trucks via CV2X Connectivity on Highways
(2024-01-03)
Intelligent road infrastructure consisting of sensors and communications is needed to deploy connected and automated vehicles (CAVs) on real highways. Such infrastructure can support the operation of CAVs (e.g., maneuver ...
