While silicon electronics has been a success in modem technologies, silicon photonics is still in development and in need of a laser source. Many approaches have been explored, from anodized silicon luminescence, to generating direct emissions by quantum-confinement, and to indirect down-conversion of a...

Perseus is a suite of tools that allows existing x86-based software (in binary form) to be optimized for commodity multi-core platforms. Optimizations are made with respect to both performance (e.g., by avoiding undesirable cache effects) and power consumption (e.g., by modulating frequency and voltage of...

Tailoring the surface properties of biodegradable nanospheres and microspheres for in-vivo blood-contacting applications includes defining relationships among chemical composition, processing parameters, nanosphere sizes and size distributions, and surface structure. Developments include: 1)...

Progress has been reported in a continuing program of molecular genetic studies of the responses of bones to mechanical stresses. Prior studies in mice and humans had provided evidence that mechanical loading stimulates bone formation and that immobilization or loss of mechanical...

A document discusses a methodology for synthesizing finerresolution data products from outputs of the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments aboard NASA's Terra and Aqua satellites. Typical MODIS ocean color data have 1-km resolution, but those in five wavelength...

The Verification and Automated Reasoning research group at Cornell University has been building an infrastructure, comprising human expertise and computational resources, for the development of secure, reliable software for critical military applications. Such software includes distributed...

Mistral Solutions (Dallas, TX) offers the PCM telemetry encoder, a fully configurable Pulse Code Modulation (PCM) onboard system for analyzing flight parameters in airborne applications. The system is designed to withstand extreme environmental conditions and is AMC PPC405-based. It is comprised of a data acquisition system, a...

The Matrix PCI Express 4-lane video cards from Great River Technology (Albuquerque, NM) are designed for high-speed ARINC 818, FC-AV, and HOTLink II applications. The cards can record or transmit video at 500 MB/s, are built with Xilinx Virtex-5 FPGA technology, and can be configured for a variety of video formats and resolutions. They...
