We propose to continue the development of software designed to model the propagation of light pulses through atomic media by including the capability to model propagation in optical cavities with active laser media, among other improvements. The software will be used to design and analyze a gyroscope based on the Sagnac effect that achieves enhanced sensitivity by employing a highly dispersive ato ...

A high-voltage, high-capacity, inexpensive cathode material for lithium-ion batteries (LIBs) is proposed. The cathode material employs carbon nanotubes and additional nanostructures to support efficient transport of Li ions. The resulting LIBs will support high transient and pulsed loads while offering enhanced safety and lifecycle performance. Proof-of-concept LIB cells were demonstrated in Phase ...

We are proposing to develop a process for large area fabrication of metamaterial films with electromagnetic responses that can be manipulated in the infrared region to enable tailored reflectivity and emissivity. Because the approach is based on metamaterials, this technique can readily be scaled to higher or lower frequencies.

New material systems are required as a result of advanced performance criteria for the next generation destroyer program and other Navy ships. As a part of these requirements there is high demand for high strength structural composites. The objective of the STTR Phase II project is to develop high strength and light weight structural composites utilizing functionalized single-walled carbon nanotub ...

Our Fused-Realities-Assessments-Modules(FRAM) enables innovative new levels and types of automated quantification strategies for combining human and system performance in real-time for fused performance monitoring and after-action-review purposes. FRAM accomplishes this by fusing output of normative models of behaviors (cognitive/procedural/team), human states (physiological/affective), system sta ...

We propose to build an emitter localization and detection system that can geolocate signals in the 800-2400 MHz range. The system can be rapidly-deployed, provide accurate emitter locations, deals with many-emitter problem explicitly, and can find low-power emitters.

The Navy has need of assessing the river environment including bathymetry, flow velocity profile, and navigational obstructions. While improvements in measurement fidelity and reduction in cost have come about by the use of multiple drifters, measurement quality is lost due to convergent drifter trajectories, and cost/risk remains high due to personnel effort required for deployment. An autonomous ...

In miniature gas turbines for UAV applications, traditional bearings exhibit a typical lifetime of only 25 hours due to excessive axial loading. Mainstream proposes to use a passive, permanent magnet thrust bearing to alleviate this problem and increase service life to over 1000 hours. Since this type of bearing is non-contacting, it can operate at very high rotational speeds with minimal heat gen ...

A rapid prototyping simulation for the Autonomous Rotorcraft Land & Take-Off (ARLTO) system will be developed to analyze and evolve requirements for the landing and take-off of a Rotary-wing Autonomous Air Vehicle (RAAV) from unprepared terrain. The simulation is based upon the Task-Pilot-Vehicle modeling system and features a UH-60 configured with a Sliding Mode Control (SCM) inner loop closure. ...
