Current research shows that failures in the standardization process are often the result of a failure of the participants to communicate or organize. To this effect, NIST has developed a tool, NIST Ontological Visualization Interface for Standards (NOVIS), with an environment for visualizing, browsing, and querying standards. Aztera will create a Computer Aided Standards Development (CASD) framewo ...

The goal of this project is to develop, prototype, and experimentally validate a new Differential Global Navigation Satellite System (DGNSS) capable of providing sub-centimeter positioning accuracy for quasi-static scientific, survey, and structural health monitoring application. The main feature of the proposed DGNSS solution is that it leverages publically available GNSS reference data from exis ...

The use of unattended floats, platforms, and drones addresses the immense challenge of cost-effectively characterizing the chemistry of the oceans. The proposed program strengthens this capability by demonstrating the feasibility of Laser Fluorescence Enhanced Flame Spectrophotometry (LFEFS) for the simultaneous and high precision measurement of calcium and strontium. These are key elements of the ...

The sodium battery using beta-alumina solid electrolyte is one of the most promising grid-scale electrical energy storage technologies that can balance the short-duration variability in renewable generation. Despite many advantages, the sodium batteries have several barriers for successful commercialization, mainly related to safety issues and high capital investment for installation. The safety i ...

The proposed project is to demonstrate a novel technique for producing GaN single-crystal boules that yield GaN wafers and substrates suitable for fabrication of GaN high-power devices. The two key attributes of the proposed novel GaN growth technique (a bulk crystal growth technique) are: a high growth rate and an ability to achieve a superior crystal quality. The novel GaN crystal growth techn ...
