ABSTRACT: The objective of this effort is to develop and demonstrate approaches for realizing metamaterial-based micro-electrometrical (MEM) ultra-low-loss non-dispersive phased array antennas for multifunction radar and communication systems in unmanned and micro air vehicles. A metamaterial based Ka-band unit cell will be designed and provide the foundation for a 4 bit phase shifter that will b ...

Using current design methods programmers cannot determine effective use of threading strategies that can maximize the effectiveness of multi-core architectures. Approaches such as effective threading strategies including, how many threads are needed, where the threading occurs, the existence of performance bottlenecks and the demands of code maintenance require domain-specific a priori knowledg ...

To maximize multicore architectures Securboration is teaming with multicore expert Dr. Frank Muller from the North Carolina State University to develop the Pico-kernel Adaptive and Scalable Operating-system, or PICASO, which has the potential for transformative advances in science and technology. PICASO puts forth novel techniques in multicore operating system design by 1) enabling predictable exe ...

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 ...

MSP is introducing in this proposal a practical approach to a family of cascade impactors capable of real-time measurement of the size-distributed mass concentration of particles in the atmosphere. Further, because of the high sensitivity of the proposed mass transducers, these impactors will also provide nearly instantaneous information about the influence of water vapor on the size distribution ...

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 ...

Photocathodes with spin-polarized electron emission are used in physics research. Current photocathodes offer high polarization, but low total currents, and have limited lifetime. Research involving these polarized electrons would be more productive if a higher electron current were provided. This program seeks to increase the delivered polarized electron current from the photocathodes by adding i ...

For several decades photomultiplier tubes (PMTs) have been the main technology for sensitive and low noise detection of photons in many high energy physics experiments. However, compared to solid-state photodetectors, PMTs are bulky, fragile, expensive, and need to be shielded from high magnetic fields and high pressures, which severely limit their application for future DOE projects. Hence, th ...
