The Phase I effort was successful in experimentally showing feasibility of a combined isotope transmitter that can be developed and demonstrated under the Phase II program. The initial experimental results give the window of gas mixtures for a stable discharge. Laser extraction tests were accomplished with C12/C13 mixtures to give guidance for further work to increase laser gain. For application ...

We propose to conduct a feasibility study for utilizing broadband sampling of the diffusive noise field in a dynamic environment. In ambient noise studies, the ability to resolve a wavefield is proportional to its time-bandwidth (TB) product. In a dynamic environment such as in the atmosphere or ocean, the nature of the impinging wave field is changing rapidly so that only short time segments can ...

Military applications, such as IRCM (Infrared Countermeasures) and stand-off sensing, require highly efficient optical sources with power outputs for room temperature continuous wave operation of several to a hundred watts in the 3-5 micron and 8-12 micron spectral bands. While quantum cascade lasers (QCLs) have become the sources of choice in these spectral regions, the only realistic option to ...

This Small Business Technology Transfer (STTR) Phase-I project will constitute design of algorithms, toolsets, and interfaces to detect and visualize complex events from video and communications data. Our proposed system would be based on a Service Oriented Architecture (SOA) which will allow users to integrate services and data from multiple sources and operate in a networked environment. The key ...

We intend to use the emerging technology of compressed sensing and related new algorithms of information science to (1)increase our capacity for hyperspectral image acquisition beyond current capacity by developing new imaging and spectroscopic systems,(2) expand the frontiers from signal recovery to new applications, emphasizing knowledge learning including target and anamoly detection, and (3)st ...

The theory of compressive sensing (CS) will be extended to the design of arrays for underwater systems. The underlying theory is applicable to arbitrary sensor arrays, but the focus will be placed on synthetic aperture sonar (SAS). The proposed research will integrate CS with the closely related and evolving field of matrix completion. Concerning the latter, it is assumed that a matrix of noisy da ...

Gallium Nitride (GaN) substrates are ideal materials for fabrication of high-power and high-frequency devices based on III-V materials. The current state-of-the-art Chemical Mechanical Polishing (CMP) methods are plagued by several challenges, including, surface charge affects due to surface contamination, and sub-surface damages, which can limit the quality of III-V devices. Furthermore, there is ...

The objective of Phase I is to identify the strengths and weaknesses of the various multi-reference coupled-cluster (MRCC) methods that have been proposed for the description of molecular states depending upon near degeneracies and non-dynamic electron correlation. Such effects are encountered in bond breaking, at transition states, for complex open shell systems like transition metal atoms, and f ...

Single-reference coupled cluster (SRCC) methods have revolutionized our ability to accurately predict molecular energies and properties. As new developments in theory and computer science extend the application of SRCC methods to larger and larger systems, advancements in coupled cluster methods for studying multi-reference systems have lagged far behind. DECISIVE ANALYTICS Corporation has teame ...
