We propose a novel and promising non-native speaker recognition system by using both high-level language cues and low-level acoustic accent cues. The system consists of a high-level language cue based sub-system and four accent recognition based sub-systems. Each sub-system can be used individually or together via system fusion. The novelty and uniqueness of our proposed approach are as follows: F ...

Increased demands for electric vehicle performance have resulted in large power requirements and the potential for extremely large fault currents. This is true not only for over-the-road electric and hybrid vehicles, but also for ships and aircraft, which are increasingly moving toward all-electric propulsion. Without fast and reliable means to limit fault currents and isolate faulted sections, ...

Nitek Inc. proposes to develop deep ultraviolet light emitting diodes having high quantum efficiency, long device lifetime, and large emission area to make usable for force protection objectives of bio-agent threat detection and maneuver sustainment objectives of potable water. The advancements in deep UV LEDs will be achieved by developing a novel vertically conducting geometry. In addition to ...

The objective of this proposal is to demonstrate the feasibility of a direct laser diode array side pumped large mode area high power eye-safer fiber laser. Traditional laser diode end pumped single mode fiber laser designs are limited in terms laser power pumping and extraction. Double clad large mode area fibers are scaleable to high output power levels. They typically utilize fiber delivered ...

In a complex theater of operations there is a need to track soldiers’ positions to keep them out of harms way. A secure, innovative dismounted identification system that will identify dismounted personnel at tactically significant ranges (1,200 meters or more), such as a long-range RFID interrogator and transponder system, is required to verify the actual location of soldiers, and precisely trac ...

This Phase I SBIR ARMY project proposes the development of 7” in diameter hemispherical spinel domes (3.5” radius, 0.18” wall thickness, 160 degree aperture) through the combination of freeze casting (FC) technology with unique nanopowder technology commercialized by MER for magnesium aluminate spinel (MgAl2O4) ceramics. These technologies allow for the production of spinel domes with high g ...

Microclimate cooling is a critical need for soldiers serving in hot climates. Power requirements for conventional cooling approaches can add considerable battery mass to the system, since refrigeration consumes a large amount of power and systems must run for four or more hours without recharge. We propose to develop an innovative, lightweight microclimate cooling system that includes an integra ...

We are proposing novel approaches for implementing a flexible, feasible and interoperable multicast admission control mechanism (McastAC) that is located at the red side of the typical Army black and red networks environment to provide end-to-end QoS assurance: • McastAC decisions are based on resource-friendly network performance estimations, which enable quick reaction to the status change of ...

Two complementary approaches to develop next generation of large area, high-efficiency and high-power deep ultraviolet light emitting diodes (DUV LED) are being proposed. Firstly, due to the lack of adequate quality native substrates, DUV LEDs are made from heteroepitaxial AlGaN films grown on foreign substrates and thus suffer from high-density of crystal defects. Large concentration of defects r ...

This program is expected to result in a significant reduction in mass of a miniature power and microclimate cooling system for the soldier compared to two independent systems. The highly integrated, and innovative approach chosen for this project will result in a gravity-independent microclimate cooling system with high coefficient of performance an minimum weight. The integrated power system wi ...
