We propose to develop a commercially adequate, robust and perfomant OWL-based Integrity Constraint (IC) validation system with several innovations, including novel debugging and explanation support for data integrity errors; incremental and optimized validation of data integrity; and a unified system for validating structured, semi-structured, and semantic data. A rigorous and formal specification ...

NOAA supports over 25,000 underwater dive programs per year. To increase the duration and depth of these dives, the use of closed circuit mixed gas rebreathers (CCRs) is being considered. As there currently are no sensors to detect CO2 levels in the breathing gas, Giner, Inc. proposes to continue development of an electrochemical CO2 sensor for CCR use. The technical innovation is the use of a ...

This SBIR project aims to develop a new class of low-field magnetic sensors based on magnetic tunnel junctions with magnesium oxide (MgO) tunnel barriers. The Phase II effort will continue the optimization of sensor performance, based on three major research thrusts. First of all, we will continue the magnetic engineering effort, turning the properties of the two key magnetic electrodes, in order ...

Even today as a highly technical and advanced world civilization, the physiology of deep sea fish and invertebrates continues to remain mysterious and poorly known. Past specimen containers fail to either have the size or volume needed or lack the robustness for high pressure containment of in many cases, lack the repeatability necessary to ensure a reasonable lifetime of continuous use. The Tec ...

Voxtel has demonstrated efficient high-speed photon counting with thresholded linear-mode avalanche photodiode (APD) receivers using multi-gain-stage InGaAs/InAIAs APDs. In contrast to Geiger APDs, thresholded photon-counting linear APD receivers are thought not to suffer afterpulsing, and can support maximum count rates (MCR) up to 2 or 3 orders of magnitude faster than Geiger APDs. However, the ...
