The goal of this Phase I STTR proposal is to quantify the necessary hardware and processing requirements to enable a ship-based radar system to automatically detect and track whales on the ocean surface at distances of 5 kilometers or more for the purposeof collision avoidance. Long standoff detection and tracking is crucial to collision avoidance since large ships, such as commercial oil tankers, ...

Inorganic/organic (hybrid) nanoreinforcements based upon Nanostructured Chemicals and POSS-modified nano/macrofillers offer alternate mechanisms to fire retarding conventional hydrocarbon-based polymers. The two primary mechanisms provided bynanoreinforcements are (i) reduced volatilization of fuel (organic monomer/polymer) and (ii) the formation of oxidatively stable, nonpermeable surface chars ...

We shall use recently developed numerical technology to compute detonation phenomena accurately,deal with mixed phase flow, high strain rate solid mechanics and complex geometry. These new techniques, developed largely by the personnel involved, includethe level set method, ghost fluid method, ENO and WENO shock capturing schemes, solid fluid interaction methodology and the fast closest point tran ...

The U.S. Navy designed high-power active sonars like the Low Frequency Active (LFA) system to counter quiet submarines. High-power transmissions from mid- and low-frequency sonars are known to cause trauma for human divers. To comply with the MarineMammal Protection Act and the LFA Environmental Impact Statement (EIS), the U.S. Navy must effectively reduce active sonar transmissions to benign lev ...
