ABSTRACT: Speech recognition technology is in wide use today and has been successfully integrated in a number of applications. Most of these applications require a microphone located near the talker. However, when a distant microphone is used where the speaker is at some distance from the microphone as in a hands-free communication, or in a meeting room, there is a major problem with the captured ...

ABSTRACT: Under the proposed effort, PSI will leverage a novel pmmW imaging technology developed under a prior Navy program to realize the low size, weight, and power sensors required for UAV implementation. This technology is based on an optical upconverted distributed aperture technology that can make use of the full aperture of the aircraft thereby maximizing achievable resolution. This sensor ...

ABSTRACT: The proliferation of autonomous- and human-machine systems necessitates the creation of new tools for system design and evaluation. Key among these are simulation testbeds that support interactions between multiple warfighters and systems, and methods for creating and integrating intelligent agent models into simulation environments. We see a significant opportunity to advance the state ...

ABSTRACT: To unlock the power of cooperating teams of autonomous cyber-physical systems (CPSs), humans must be able to effectively, reliably, and safely task them using high-level goals. SIFTs Playbook interface approach provides goal-based tasking for multi-agent autonomous missions. SIFTs Cooperative Intelligent Real-time Control Architecture (CIRCA) automatically synthesizes and verifies r ...

ABSTRACT: A range segment upgrade for Air Force satellite control network (AFSCN) will significantly improve system effectiveness via spectrum sharing and seamless interoperation. However, the upgraded system requires new capabilities such as real-time and accurate RF interference detection and mitigation, array antenna backlobe/sidelobe suppressions, accurate performance degradation prediction, ...

There are many challenges in creating Air Force systems that are resilient against cyber threats. The cyber environment and its threats are highly dynamic, requiring practices and training to be dynamic as well. Cyber threats must be considered during th...

With today's IRLED devices, >99.4% of input electrical power is converted into parasitic/waste heat. Moreover, as the local temperatures of the pixels increase due to the generated heat, IRLED optical efficiency is further reduced. Overall this severely ...

Our Phase I work focused on improving modeling and simulations so that the impact of autonomous systems in the battlespace could be better understood. As we have trained our attention on Phase II, it has become increasingly clear that the work we are doing to improve the modeling and simulation of autonomous systems also provides significant leverage for the development of the intelligent behavior ...

Automatic speech recognition (ASR) technology is in wide use today and has been successfully integrated into a number of applications. Although there are also many potential applications for automatic speaker identification (SID), SID accuracy rates are generally not sufficient for widespread use in practical applications. For high accuracy ASR and SID, the microphone must be located near the talk ...

The Army is frequently forced to operate in hostile climates. Heavy fog, rain, snow, and dust storms can inhibit the performance of tracking technologies such as mid-wave infrared cameras. In such conditions, Army early warning systems are blinded and put personnel and assets at risk. There is a specific need for a degraded visual environment (DVE) penetrative target tracking solution. Radio fre ...
