DHP is seeking new image compression technologies that will retain diagnostic quality and reduce the burden of digital medical image transmission on the militarys tactical networks.ATA is proposing to tailor the latest state-of-the-art commercial image compression algorithm, the Main Still Picture Profile of the High Efficiency Video Coding (HEVC) standard, for medical imagery.HEVC has been shown ...

Orphaned radioactive sources represent an ever-increasing security threat as potential materials for fabrication of "dirty bombs" and other illicit applications. According to the 2008 NAS report, the major radioisotope sources used in the United States are Cs-137 (~3M Ci @662keV) and Co-60 (~200M Ci @1.2-1.3MeV) for industrial radiography, measurement and irradiation applications. A large number ...

A robust system level design process will be used to identify the design of transparent tapered resistive (TTR) elements, including the materials, fabrication processes, and lifecycle costs. The transparent tapered resistive film will be designed to provides a tapered resistive layer across the film while remaining transparent in the visual and near-infrared optical bands for use in radio-frequenc ...

Vibrant Corporation and Sandia National Laboratories (SNL) propose to apply Process Compensated Resonance Testing (PCRT) to the DLA's need for an NDI method to detect counterfeit, nonconforming and improperly processed materiel. PCRT collects and analyzes the resonance frequencies of a component to detect structural defects, characterize material, analyze population variation, monitor manufacturin ...

Single chirality of single-walled carbon nanotubes (SWCNTs) is critical for their superb mechanical, thermal, optical and electronic properties. All known methods for producing nanotubes give mixtures of tubes with different chiralities. Physical separation of SWCNT by chirality is thus an enabling step for many potential applications and fundamental studies. The existing anion exchange resins are ...

The applicant will develop a wave energy harvesting system for NOAA buoys. It will ve entirely self-contained (no protruding elements), modular, scalable, and easily deployed. The system employs a unique, inertial mechanism that responds to acceleration forces created by waves. This mechanism will be combined with (1) a proprietary generator that is sensitive to very low levels of torque and ha ...

Storm surge poses a grave threat to both life and property as hurricanes make landfall. The ability to monitor surge in real-time using a densely-space network of sensors with integrated data recording and telemetry would provide NOAA with a unique capability. Our approach is to offer a system which incorporates a flexible multi-modal data acquisition platform with integrated telemetry for real-ti ...
