Toyon Research Corporation, together with the University of California, Santa Barbara (UCSB) propose to demonstrate a GPS-denied Local Carrier-based Precision Approach and Landing System (LC-PALS) that enables 3-D position, navigation and time (PNT) for platforms within range of an aircraft carrier equipped with one or more ADEPT-compliant beacons. Unlike the Global Positioning System (GPS), which ...

Thousands of years of evolution have produced the human vision system that computers cannot replicate well. Humans are still unsurpassed in their ability to search for objects in visual scenes. To successfully detect objects in cluttered scenes, the human brain is thought to rely on multiple factors: prior probabilities of object occurrence, global scene statistics and object co-occurrence. Machin ...

Spontaneous emission is a quantum mechanical process that represents the main source of phase noise in state-of-the-art semiconductor lasers, limiting their coherence, and their suitability for high-speed communication and sensing applications. This proposal aims to develop ultra-high coherence semiconductor lasers on the Silicon/III-V platform with a quantum linewidth of

Few-cycle mid-infrared lasers are in high demand for a variety of practical applications including remote sensing of chemical and biological species. NP Photonics and the University of Arizona propose to develop a wavelength tunable and power-scalable optical parametric laser system covering 8-10 micron and capable of producing collimated few-cycle pulses with pulse energy > 100 microjoules. A ful ...

Empirical-based mathematical framework and computer algorithms, for representing human perception and cognition processes and limitations, which influence the recognition of salient information about rapidly changing events.

Current decision tools often omit important situational context. Unfortunately, this can lead to dangerous and costly errors, as context drives decision making. For example, in operational navigation planning tasks, decisions must be made that rely on multiple information sources of different fidelities and uncertainties. Furthermore, after obtaining additional information the necessity for replan ...

Leveraging the results of our Phase I work, the Torch Team proposes to execute laboratory-based experiments to elucidate fundamental micro-debris formation mechanisms to improve optical modeling of impacts. Optical signatures from impacts collected over the last decade have identified definitive micro-debris parameter trends. However, current theories have difficulty reproducing these optical ob ...

We propose a new fiber WDM fabrication method for single mode high power fiber laser. Our new approach will enable kW operation for both single mode fiber WDM and PCF WDM. In Phase I, a proof of concept experiment has been demonstrated. In phase II, we will target at delivery of a reliable prototypes for both step index fiber WDM and PCF WDM.

A critical step in the extraction of elements from ore, especially rare earth elements that are found in complex minerals, is separation. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then ca ...

The Alpha STAR Corporation and the University of Akron STTR Phase II proposal will establish ASTM standards test methods to determine relevant ceramics matrix composites (CMC) delamination crack growth resistance (CGR) material properties (Mode I & Mode II)under service load temperature conditions. Phase Ii will expand on Phase I results, conclusions & recommendations. Emphasis will be on testing ...
