Abstract:The damaging effects of age, poor framing and general wear and tear on traditional ship based transparent armor windows leads to delamination or other failures within the window. These failures compromise safety not only from ballistic threats but also by obstructing outward views. A new two-pane… more
Abstract:ABSTRACT: Satellites that operate in low Earth orbit undergo significant transient and non-uniform environmental thermal loads. Further, the payloads on many satellites are also highly transient. Because of the combination of these two conditions, time varying thermal distortions are often… 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.
