The feasibility of developing a photonics-based, real-time, high-power-radio-frequency (HPRF)/high-power-microwave (HPM) detection-and-analysis system is to be investigated. Design and development of foundational elements will take place to demonstrate how self-contained, shielded, photonic and source-power subsystems, interconnected to a network of non-polarimetric sensors via optical fiber, will ...

We propose to create TEAMMATE, a system that can give individual instructor trainees Tailored, Extensible, Automated Mastery Measurement for Actionable Teaching Evaluation. TEAMMATE will combine low-cost, COTS sensors like a camera and microphone with intelligent software to assess multiple key aspects of verbal and nonverbal communication. Like a peer observer in civilian teacher training, TEAMMA ...

Under this topic, Advanced Cooling Technologies, Inc. (ACT) proposes to develop a software toolset to design and optimize the control architecture for two-phase thermal management systems. The approach with make use of physics based models to capture the component and system level response with high-fidelity. By building on previous successful modeling and experimental validation efforts, the rese ...

The utilization, and thereby, threat of unmanned underwater vehicles (UUVs) is experiencing a significant increase throughout the world. UUVs can be used to track vessels, covertly map ports, and attack targets. UUVs are inherently quiet targets making them difficult to track via traditional acoustic methods. To counter the threat presented by covert UUV activities, other detection and tracking me ...

Low cost and high capacity make lithium sulfur batteries (LSB) the next generation of lithium ion batteries. Practical application of LSBs remains limited by low utilization of sulfur and fast capacity fading of sulfur cathodes. The root causes are poor electronic conductivity of the cathode combined with high solubility of intermediate polysulfide products formed during cycling. To overcome these ...

Synthetic aperture radar (SAR) has the ability to detect and discriminate slow moving (= 10 knots) low radar cross section (RCS) objects such as small surface vessels and surface signatures in maritime environments at low-to-mid grazing angles. The physical mechanisms for detection and discrimination are made possible by the combination of coherent and non-coherent scatting phenomenology associate ...

Voci Technologies Incorporated (Voci) is the leading small business developing accelerated Human Language Technology based solutions. In Phase I of this SBIR, Voci demonstrated the feasibility of automatically clustering audio with useful false-positive and false-negative rates. In Phase II, Voci is is partnering with Vickers & Nolan Enterprises to develop a prototype Automated Speaker Clustering ...

Access to experienced technicians is not always available to a maintainer at sea. Correcting naval electronic systems issues as they occur can leverage accumulated knowledge that resides in databases, detailed test plans, repair procedures, and other documents if available to ship-based maintainers. This effort is to develop an Interactive Instructor chatbot technology that is an interface between ...

Mycotoxins are fungal toxins to which exposure frequently results in incapacitation or even in death. Natural outbreaks of mycotoxin poisoningare common worldwide. Due to its physical-chemical properties, high toxicity and relative ease to produce, mycotoxin T-2 is classified as apotential biological warfare agent. Currently there are no FDA approved medical countermeasures available for T-2 mycot ...

In order to be an effective EM radiator, monopole antennas must be ideallywavelength. For HF frequencies, this can result in a significantly long radiator. This long radiator, when deployed, can accidentally contact a HV source such as an overhead power line. The results of such a contact can be devastating for the radio operator and potentially nearby soldiers. Because of this threat, a simple so ...
