Semantically Linked Data is widely seen as a revolutionary approach for maximizing the usefulness of existing and future information. In the materials domain, semantically linked materials data holds considerable promise with the ability to facilitate materials research and product development, improve communication, and open up avenues for new types of materials informatics. But realizing the pro ...

This effort proposes to develop a toolset to evaluate the effectiveness of a safety-controller that monitors a learning-based autonomous control system. The traditional use of deterministic verification techniques for real-time monitoring is not feasible in the presence of uncertainty. This effort would advance the recommended verification techniques to include non-deterministic approaches. The ...

Barron Associates has assembled a team of researchers that include Dr. Sayan Mitra of the University of Illinois and Dr. Ufuk Topcu of the University of Pennsylvania. They will spearhead three complimentary investigations into the development of verification and validation (V & V) approaches for adaptive systems protected by run time assurance (RTA) mechanisms. Two of these approaches involve us ...

This DOE SBIR program would develop a manufacturing process to produce plastic optical fibers with bandwidth, bend loss and ease of installation significantly improved over currently available products. Current polymer optical fibers are manufactured using bulk polymer processing methods. These methods limit the types of fiber waveguides that may be formed, so significantly l ...

Advances in soft X-ray detector technology have enabled higher count rates while maintaining high spectral resolution. These new superconducting detectors share the common form of a pixilated active area that must be operated in the milli-Kelvin temperature range below the boiling temperature of liquid helium. Because the cryogenic detectors are under high vacuum and must be able to sense ambien ...

Innovative, fast, ultraprecise and affordable metrology instruments are needed to ensure that grazing incidence optics can meet emerging requirements for DOE Basic Energy Sciences (BES) synchrotron and FEL x-ray light sources. Currently, there is not a suitable instrument available in the United States that will allow manufacturers to produce such demanding optics. This PH I SBIR will focus on de ...

Mesa Photonics proposes a new method for online diagnostics at x-ray free electron laser facilities. This diagnostic can be fully automated, switching among alignment, jitter measurements, and pulse characterization. In this SBIR project, Mesa Photonics will develop a new diagnostic for measuring the time arrival between optical and x-ray ultrafast pulses. This technology is critical for the dev ...

Low cost and accurate monitoring of sequestered gases such as CO2 is critical to insure that sequestered gases are not reentering the atmosphere. Management requires, in part, improved atmospheric and ground monitoring of greenhouse gases through sensors capable of measuring the flux, concentration and the carbon isotope of CO2 with high accuracy. These Monitoring, Verification and Accounting ...

Generation IV Gas-Cooled Reactors require advanced structural materials capable of resisting extreme conditions of radiation exposure, high heat flux, corrosive environments and thermo- mechanical stresses. Metallic alloys such as stainless steel and Zircaloy used in fabricating fuel assembly grids, nozzles, strainers and spacers for generation IV Gas-Cooled Reactors, run the risk of melting when ...

Stratus and stratocumulus clouds with low drop concentration and large drop diameter are scientifically very important, because this is the regime in which drizzle drops are formed. The formation of drizzle can lead to a rapid modification of the cloud droplet size distribution, which in turn has a strong influence on the cloud & apos;s radiative properties. Because stratus and stratocumulus cl ...
