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

72984S03-I Currently available methods impose limits on the processing of multi-filamentary, superconducting wires used in high energy physics experiments. These limits can be severe when one of the wire components has a mechanical strength substantially smaller than the other component(s), and can eliminate many desirable wire designs from consideration. Niobium-Tin and Niobium-Aluminum are e ...

Significant fuel cost savings can be realized in the automotive and aerospace industries by employing lightweight materials in the design and fabrication of vehicular components. To date, the exploitation of lightweight magnesium and aluminum alloys in component fabrication has been restricted due to their limited formability at room temperatures in conventional metal stamping processes. Hydrofo ...

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 ...
