In composites, not only can properties vary with load direction, fiber based composites also offer the unique ability to tailor material properties locally. Localized matrix or fiber architecture changes can meet local mechanical, electrical, or thermal loads within a component or vehicle, without weight penalty or resort to additional external structures. In Phase I, the team used 3TEX 3-D wea ...

Strength and durability of commonly used bonded and bolted composite-to-composite and composite-to-metal structural joints suffer from sharp geometry variations, mismatch of elastic moduli, Poisson’s ratios, coefficients of thermal expansion and thermal conductivity of the adherends, altogether causing high stress concentration and premature joint failure. The proposed work is focused on develop ...

Over the past few decades, computational electromagnetics (CEM) researchers have been making steady progress towards the development of efficient algorithms, such as the Method of Moments (MoM), for simulating scattering from electrically large targets. Unfortunately, such techniques have proved too computationally demanding because they require the solution of an often very large and dense matri ...

Photonic crystals have led the way for miniaturizing application specific optical integrated circuit (ASOIC) to a scale comparable to the wavelength of light which in turn made them a good candidate for next generation high-density optical systems and interconnects. Polymer based Photonic Crystal structures have potential applications in optical integrated circuits, optoelectronics, optical switch ...

This SBIR will develop a new class of computer architecture called an “agent based computing” module (ABC Machine) that enables “cognitive computing” algorithms to be implemented effectively on a large scale. The ABC Machine is a biologically inspired architecture derived from the field of “membrane computing” and is also based upon “statistical dataflow computing”. It operates in ...

Experimental tests in Phase I have shown the fuze shock absorber system capable of reducing shock peaks by a factor of three, and the associated jerk by an order of magnitude. The Phase II work will be devoted to exploring the performance space of this jerk-reduction system as a function of its material properties and physical configuration, as well as the fuze mass. LRK Associates will design a ...

The Phase I work has shown the technical feasibility of creating new, equivalent-accuracy algorithms for optical simulation with smaller operations counts than existing Fourier methods. These will be helpful in speeding up extended scene imaging simulations used in laser weapons' systems performance evaluations. However, the computational efficiency advantage of these new algorithms over Fourier ...

Information Management is an important component in the development of viable information sharing systems, such as JBI, where shared information may be manipulated to derive further information. The qualities of such derived information depend on qualities of the contributing information and of their sources. Determining information quality requires propagation of qualitative and pedigree data abo ...

Signal Innovations Group (SIG) and its Fast Track partner, Integrian (www.integrian.com), propose development of an adaptive video sensing system, with a focus on intelligence, surveillance, and reconnaissance (ISR). The proposed adaptive system is applicable for ISR in general environments, addressing base and port security, as well as urban and suburban sensing during wartime and peace-keeping o ...

State-of-the-art radar combat ID (CID) must address target identification in complex environments, often with very limited measured training data. Consequently, the algorithms frequently rely on data computed via numerical models, as a function of required sensor conditions (bandwidth, target-sensor orientation, polarization, etc.). Such data are usually computed using approximate high-frequency ...
