"We propose a directional, broadband, highly efficient underwater acoustic transducer using a baffled cylinder made out from piezoelectric single crystals. The prospective application areas will be for an underwater acoustic modem communication andAutonomous Underwater Vehicles (AUV), in which high efficiency of the transducer system is required due to the limited energy availability (battery) an ...

"This proposal is for the development of a high sensitivity pressure gradient acoustic motion sensor (accelerometer) of the flexural plate type using piezoelectric single crystals. The pressure gradient acoustic motion sensor is based on flexural plateelements operating below resonance in the accelerometer mode. The high piezoelectric coefficients for single crystals is ideal for increasing the ...

"Coprime proposes to investigate the applicability of learning-based source separation methodologies to the problem of multiple targets in a complex acoustic environment. The Phase I effort will focus on identifying viable learning-based source separationalgorithms specifically tuned to the multiple combat vehicle scenario. A prototype architecture will be developed and numerical software rapidly ...

"Recent advances in remote sensing technologies through the availability of more sensitive instruments, and improvements in geo-location technologies and analysis software have resulted in significant strides in the successful application of high resolutionremote sensing to feature identification such as soil disturbances. These strides have been achieved by field-oriented remote sensing experts, ...

Because of the impact of diseases on production and the environmental devastation wrought by commercial aquaculture effluents, modern methods of intensive aquaculture are evolving which rely heavily on the re-use of water. This proposal addresses the need for modular technology in closed loop aquaculture operations by enhancing the performance of a fluidized bed biofilter with low- frequency acous ...
