Scientific Solutions, Inc. (SSI), teamed with BAE Systems and Southall Environmental Associates, Inc. (SEA), proposes to investigate the feasibility of using hull-mounted active sonar integrated with above-water sensors, specifically radar and EOIR, to autonomously indentify and track marine mammals from transiting surface ships at ranges out to and beyond 1,000 yards. Active sonar, radar, and EO ...

There is a critical need for DoD to develop power sources that will increase the mission lifetime for unattended sensors and sensor radio networks. In order to take advantage of recent advances in extremely low power subthreshold circuits to greatly exte...

Under the DARPA sponsored Naval Advanced Amorphous Coating (NAAC) program, a novel, thermal sprayed amorphous metal coating has been developed. Such a coating has demonstrated superior mechanical and corrosion resistance properties. Although the coating is designed to be life-of-ship, the application and operational conditions may compromise the integrity of the coating. For example, the applicati ...

This project describes research that will lead to the commercialization of the Tool Dashboard, a new technique for pre-process milling parameter selection. In this approach, dynamic models of the cutting tool and holder will be analytically coupled to spindle-machine measurements to predict the tool point dynamics. Given this information, stability lobe diagrams, which display stable and unstable ...

Existing machine tool metrology methods measure the quasistatic errors of a machine tool and, thus, evaluate its static positioning accuracy. Yet machine tools are dynamic, they do not stop and pause in an effort to reach a programmed position. Additionally, current techniques do not identify all of the errors, many of which significantly impact the volumetric accuracy of the machine. Almost immed ...

In modern battlespace, deployment of chemical and biological agents by our adversaries is a threat that needs to be addressed. These agents are cheap to manufacture and easily available. Their effects can be devastating to our troops. Detecting chemical and biological agents often require bulky equipment in a laboratory. Identifying the agents could take many minutes in such facilities. A more eff ...

"Air Vehicles that are able to fly autonomously into confined spaces, land, shutdown, collect information, restart, and return to base, present an interesting propulsion challenge. Critical requirements of the propulsion system include:¿ Extremely high power per unit weight and per unit volume,¿ Extremely reliable, compact, and lightweight starting system¿ High fuel efficiency¿ Mult ...
