Abstract:While mechanical damage to pipelines is a common occurrence, the impact of mechanical damage on pipeline remaining life is not easily determined. The mechanical damage features, such as residual stresses and stress concetrations, will determine the effect of the damage on pipeline remaining… more
Abstract:Automated vehicle counting technology has been in use for many years, but developments in automated pedestrian counting technology have been limited. Pedestrians are more difficult to detect, track and count, than motor vehicles because their paths are much less constrained. In Phae I… more
Abstract:Photon-X is proposing to develop a 3D roof imaging system to monitor vehicle roof deformation during vehicle rollover testing. The system will provide photographic resolution imagery with the ability to track the dot pattern on the vehicle roof. The Photon-X spatial phase 3D imaging… more
Abstract:Individual differences in vulnerability to sleep loss and fatigue from extended work hours and night work are a substantial problem in transportation work schedule development, fatigue risk management strategies, and prediction of performance impairment in real-world operations. This… more
Abstract:Rail vehicle distance traveled measurements don't currently meet the precision requirement of 5ft./mile. An innovative microwave technique is proposed using two X band transceiver assemblies separated by a known distance. Reflected energy from metal objects such as tie-plates or… more
Abstract:Solar Roadways Incorporated envisions replacing current asphalt surfaces with modular Solar Road Panels: structurally-engineered solar panels that can be driven upon. The roadway will generate electricity, become our nation's power grid, make all-electric vehicles practical, and… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
