The open-source network management software ecosystem is currently a collection of loosely-related projects with poor support for long term planning and high-level network information. Network planners have few free tools to help them balance the many variables in potential network expansions (including cost, performance, and energy usage), and few free tools to communicate these plans with manag ...

One of the most important numerical problems in science and engineering is that of finding the eigenvalues and eigenvectors of large-scale matrices. Methods for the solution of these problems, usually called eigensolvers, are fundamental to many industrial and scientific applications ranging from computational chemistry problems to structural design, to other modeling- and simulation- intense disc ...

To meet future power generation needs, Florida Turbine Technologies, Inc. (FTT) proposes the development of an innovative design approach to provide a highly durable contactless air riding rotating-to-static seal. Rotating-to-static seals are critical components of all gas turbine engines. The seals can significantly affect the efficiency, operability, and durability of a gas turbine engine. As su ...

SOFC technology promises to provide an efficient method by which electricity can be generated from coal-derived syngas, biofuels, and natural gas, while increasing energy security and reducing greenhouse gas emissions. The large capital costs attributed to the cathode low performance and long-term stability issues are a current limitation of SOFC technologies that must be addressed before commerci ...

We are improving critical technologies needed for the development of laser-driven, table-top ultrafast x-ray sources suitable for ultrafast characterization of transient structures of energized molecules undergoing dissociation, isomerization, or intramolecular energy redistribution. In this SBIR project, Mesa Photonics will develop an X-ray ultrafast laser pulse measurement instrument for complet ...

Mesa Photonics plans development of a remote sensor to be used to detect clandestine nuclear material processing. We have identified a volatile chemical that is indicative of key steps in uranium isotope enrichment, and can be detected readily at low concentrations using optical methods. Small plumes that are about 1 m across and containing as little as 20 parts per million (ppm), or less, of th ...

Seismic detection systems are one of the primary means used to monitor subsurface nuclear explosions. Consequently, the study of previous seismic events provides a critical underpinning for ongoing nonproliferation efforts. In this proposal, Retriever Technology will continue its efforts to develop accurate and automated software to extract digital X-Y trace information from historical analog sei ...

Diamond crystals with small total thickness variation (TTV) and local thickness variation (LTV) values are needed for position sensitive fast particle detectors for particle tracking/timing, and detecting direct/indirect beams. The fabrication of ultra-flat, low surface defectivity diamond detectors represents a major technological challenge. Although current commercial technology can produce 100m ...

DOEs efforts to monitor legacy sites for groundwater contamination would benefit from turn-key systems that can measure metal contaminant concentrations in situ. Southwest Sciences proposes to develop a micro-fluidic sensor for measuring heavy metals in groundwater by measuring their uv-visible spectra. High sensitivity will be obtained using cavity enhanced spectroscopy. A novel cavity enhanced o ...

X-ray absorption spectroscopy is a widely used experimental technique for studying the composition and chemistry of materials and is one of the driving forces behind the explosive growth of synchrotron light sources and their increase in brightness by many orders of magnitude. However, advances in detector technology have not kept pace with advances in synchrotron brightness, leading to limitation ...
