In Phase I, we will investigate a case-based reasoning (CBR) approach to intelligent tutoring systems (ITSs) and explore the feasibility of semi-automated/automated course authoring techniques to speed collection and structuring of domain knowledge. We will develop a prototype example-based ITS, enhanced with multimedia, within a specific Navy instructional domain and a generic ITS architec ...

In Phase I, we will investigate a case-based reasoning (CBR) approach to Operator Assessment and Operator Machine Interface Enhancement and explore the feasibility of semi-automated/automated domain knowledge entry techniques to speed collection and structuring of domain knowledge. We will develop a prototype case-based Operator Assessment and Operator Machine Interface Enhancement System (O ...

Inertial navigation systems for airborne applications use three axis accelerometers and three axis rate gyros, and in many cases additional inputs using GPS and other sensors. The objective of the proposed work is to replace the expensive rate gyros with rate estimates based on multiple low-cost accelerometers. The error characteristics of the accelerometers, chiefly the bias stability and broadba ...

Navy aircraft are equipped with an On-Board Oxygen Generation System (OBOGS) to supply the pilot and the crew with supplemental oxygen for high altitude operation. However, Navy aircraft are usually closely spaced while waiting for take-off from aircraft carriers, and the jet engine exhaust contaminates the bleed air used to supply oxygen to the pilot and crew. Among the contaminants in the engine ...

Sporian Microsystems Inc. has spent the last several years developing polymer derived SiCN sensor and associated packaging technology for application temperatures up to 1350degreesC, and demonstrated them in the combustion environments of a range of commercial burner rigs and aerospace turbine engines. Based on our expertise in high temperature materials and packaging processes, we propose to deve ...

Transmission of very wideband signal transport and processing. During Phase I, a reduced scale feasibility model of a one-dimensional (1-D) WAAOD will be fabricated, tested and demonstrated. The performance goals include 50% efficiency, 5¿ input angle, 30MHz bandwidth, and 1000 spots.

The design of a phased array antenna to be integrated with Microwave Power Module (MPM) is proposed. The array will be scan compensated to maximize the scan volume. It will consist of dipole radiators, balanced feed lines, a planar Marchand balun. The array, not including the microwave power modules, will be very thin (approximately 1 inch).

Multipaction is one of the most significant limiting factors to the dynamic range and utility of the vacuum-based radio frequency (RF) devices. If not mitigated, multipaction leads to operational impairments or even permanent damage to the exposed components. RadiaBeam Technologies proposes to utilize a magnetic isolation approach to reduce or eliminate multipaction in critical system components. ...

Work to be performed in this program is based upon years of innovative technology development invested by personnel at Nova Research. Techniques proposed here are patterned after biological principles which, when applied to finding targets which are moving against highly cluttered infrared backgrounds, will be shown to exhibit remarkable performance. Sensor and data fusion techniques may ...

One of the key goals of strengthening maritime security is to increase maritime domain awareness, involving a combination of intelligence, surveillance, and operational information to build as complete a picture as possible to assess the threats and vulnerabilities in the maritime realm. Maintaining coherent situation awareness is essential for making informed timely decisions aimed at detecting a ...
