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 ...

AEgis Technologies Group, Inc. is pleased to present this proposal for a Phase II SBIR entitled,

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- ...

The thermal protection system (TPS) community is in critical need of a newdesign paradigm if the vision of low maintenance, high sortie rate spacevehicles is to be realized. A revolutionary change is needed in the TPSdesign approach and in the use of innovative materials that can survive longdurations in an extreme heating environment without significant ablation.Low erosion, low conductivity mat ...

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 ...

To develop algorithms, software, and/or hardware necessary to collect, process, and fuse information from multiple sensors based on multiple platforms (XBR, SBIRS, EKV, UEWR) in real time in order to improve acquisition, tracking and discrimination ofthreat objects in a cluttered environment, advanced sensor fusion techniques will be investigated. Automated abductive inference (best-explanation re ...

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 ...

Applied Optimization proposes a new midcourse discrimination algorithm to identify a RV, which is concealed in a balloon, from an empty decoy balloon, for the situation of daytime missile attack. The algorithm is based on a calculation that a sunlitballoon, when vented, will collapse by over fifty percent of its size within two minutes, due to solar radiation pressure. We show that a baseline deco ...
