The work proposed here presents a novel approach to channel coding which will provide flexibility and robustness which are necessary to alleviate many significant limitations in current RF communication systems. The proposed approach is entitledTail-Biting Circular-Trellis Block Coding (TBC2). This family of coding methods provides unique advantages in the tactical military communication environm ...

This Research and Development (R&D) effort will produce an architecture and prototype for performing quick-look analysis of Electromagnetic (EM) Compatibility (EMC) using Modeling and Simulation (M&S) technologies. The target domain will be aircraftsustainment and will focus on the insertion of commercial-off-the-shelf (COTS) technologies into existing aircraft. COTS technologies provide a cost- ...

Human ability to attend to a single voice in the presence of background interference is remarkable. If this could be imitated in practical technology it would be of great benefit for automatic speech recognition and other applications. Researchers at OhioState University have demonstrated computational methods for separating speech from interfering sounds that imitate human auditory processing, an ...

Sandwich structural designs are the most weight efficient concepts for stability-critical components such as control surfaces. The objective of Phase I of this study was to demonstrate the feasibility of producing a honeycomb sandwich structure using aunique Double Wall Honeycomb design. This new ARDL honeycomb design is called Hexagonal Double wall structure or

This is the technical abstract. This is the anticipated benefits

Applied Optimization proposes to develop 3D Simulation of LAM, and verify its accuracy by correlating its results with microstructure data at the Boeing Phantom Works, for parts that are different from each other in terms of substrate and rib thicknesses,and build height. The simulation will model laser-powder-substrate interaction, using a combined analytical-numerical approach, such that it is t ...

This Phase II SBIR program seeks to create nanofiber reinforced polymer composites with superior properties for use in aircraft applications. Property targets include electrical conductivity of 25 S/cm and thermal conductivity of 50 W/m-K, withoutdegradation in mechanical properties. Materials to be used include low cost carbon nanofibers, metal-coated carbon nanofibers, and a variety of thermos ...

Under Phase I effort, Applied Thin Films, Inc. (ATFI) discovered a new process to deposit oxide buffer layers for HTS coated conductors that is economical, scalable, and has demonstrated excellent performance with YBCO films (current densities of 1MA/cm2). The process is called ECONO (Epitaxial Conversion to Oxide via Nitride Oxidation) which is now being considered as the primary contender for t ...

This research will determine extent and nature of the neutralization of bacterial spores when they are exposed, for very short times to high temperatures, pressures, and chemicals important in Agent Defeat weapons.. An exposure system will be constructedcapable of providing the ultra-short exposure times (on the order of ms) that are characteristic of bomb explosions and will be capable of exposi ...
