In this STTR, OASIS Inc, with partners the Massachusetts Institute of Technology (MIT) and the Applied Physics Laboratory University of Washington (APL-UW) proposes to develop an innovative, interactive submarine acoustic counter detect TDA for use by the Submarine Mission Planners, within the AN/BYG-1. Communicating the environmental and tactical uncertainty is of primary importance when present ...

Combustion instability, or screech, occurs in many modern gas turbine systems, and is due to the complex physical coupling of the acoustic resonances in the combustion chamber with fluctuations in the heat release of the combustion process. These instabilities can produce large pressure fluctuations that can be severe enough to damage engine hardware. Next-generation gas turbines will increase the ...

Intelligent Automation, Inc. (IAI), and its sub-contactor, Professor Carl G. Looney from University of Nevada propose a highly innovative approach for Level 2+ information fusion using hybrid data fusion with adversarial Markov game, named a Game Theoretic Approach for Threat Prediction and Situation Awareness. The primary goal is to investigate and demonstrate the effectiveness of Markov game the ...

In Phase I, we have developed new technologies used for undersea submarine detection. Our system is based on the signal cluster trending analysis for submarine detection and statistical model for false alarm mitigation. We have tested our system with DADS data from six sensors placed in two sensor arrays. Based on our test results, we have been able to detect all the targets listed in the ground t ...

An OmniGuide fiber is a hollow-core fiber which employs a dielectric omnidirectional mirror to keep light confined to its core. These novel fibers are ideally suited for ultra-low loss optical transmission and for flexible delivery of high power lasers. Prior to and during our Phase I effort, we have developed a wide range of tools to simulate the performance of OmniGuide fibers and related stru ...

The goal of this Phase II research is to synergistically combine the novel Electrical Resistance Change Method (ERCM), the guided wave inspection method, and the robust processing algorithms for nondestructive evaluation and inspection of composite structures. The ERCM has key advantages such as low cost, no strength reduction, the capability to detect and locate delaminations and cracks, no need ...

The goal of this STTR program is to formulate a template-matching operation, with perception-related rules of integration over time and frequency at its core, in the context of human perception of degraded speech. In Phase I we focused on implementing signal processing principles realized by the auditory periphery in providing the observed graceful degradation of human performance in noise, a prer ...

Collecting and understanding marine bioluminescence (BL) distribution data is an important Navy requirement for strategic operations. Bioluminescence profile, spatial distribution, and temporal data can be used to understand the vulnerability of covert operations or to determine the detection threshold of hostile forces. Additionally, the low-cost collection and cataloging of this information wil ...

To address the Navy"s need for a common, scalable, platform for multi-modal 1pA level current sensing for Electrocardiogram (ECG), Electroencephalogram (EEG), and Electrodermal Response (EDR) to be fielded as a miniature wearable device with non-contact electrodes, Sentient and the State University of New York (SUNY) propose to develop the Bioelectronic Fusion Sensor System (BioFuSenS) that will a ...

Pharad is teaming with the Applied Physics Laboratory of The Johns Hopkins University to propose and investigate the feasibility of a novel, broadband photonic linearization circuit based on a feedforward technique for airborne military communication platforms. The circuit will have the ability to achieve all-order distortion and noise suppression and be suitable for both directly and externally ...
