The proposed enzymatic fuel cell (EFC) will leverage… more
Abstract:The overall objective of this effort is to identify, and validate a suitable methodology and the associated multi-scale computational technique for predictive assessment of corrosion fatigue damage in Naval aircraft. Annual costs for corrosion inspection and repair of military aircraft are estimated… more
Abstract:Low back pain while piloting military air vehicles is a significant operational and health problem. Seating, task posture and vibration are considered major lumbar pain contributors. The asymptomatic pilot starts to experience pain and repeated painful episodes lead to pain sensitization and chronic… more
Abstract:DESCRIPTION: Pulmonary drug delivery is increasingly used for both treatment of lung diseases (such as asthma and chronic obstructive pulmonary disease) and in delivering drugs to the systemic circulation. To reach the desired effectiveness and safety oforally/nasally inhaled drugs, appropriate… more
Abstract:The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a… 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.
