We propose a rapid mapping and 3-D visualization system especially suited for inside buildings, tunnels, urban canyons, and other environments where GPS may be poor or not available. The system--which was fully demonstrated in our Phase I effort-- includes mobile Sensor Nodes that wirelessly supply compressed 3D range data and color imagery to a central Fusion Node. The Fusion Node runs 3D recon ...

ABSTRACT: The innovation proposed is a computationally-tractable, physics-based, portable turbulent combustion modeling strategy for application to a wide range of Air Force aero-propulsive systems, including augmentors, liquid rockets and scramjets. This modeling strategy will be implemented within an Application Programming Interface (API) library suitable for easy integration within Air Force ...

ABSTRACT: Due to scarcity of spectrum, Dynamic Spectrum Access (DSA) becomes a needed technology to improve the utilization of electromagnetic spectrum for DoD satellite communication. However, current DSA approaches are developed for terrestrial communications without addressing the unique challenges for SATCOM environments such as error-prone spectrum sensing, high mobility, and large coverage. ...

ABSTRACT: Coordinating and sharing information across multi-level security (MLS) networks are of great interest in many military applications. However, it is very challenging to accomplish those goals due to the heterogeneous security classifications of different network domains. The recent proposed cross-domain solutions (CDS) provide initial steps to make such applications possible. However, th ...

This project address the fabrication of solar blind detectors from the MgZnO material system. Both MBE and MOCVD material growth techniques will be used for deposition of the required material layers. Simulation software we be used to aid in the design of the photodetector structure. Devices will be fabricated from the grown structures and their electrical and optical characteristics determined.

Research is proposed for the development and implementation of state of the art, reduced order nonlinear aeroelastic models for multidisciplinary/multi-fidelity optimization problems. Highly efficient and accurate aeroelastic simulation tools will be constructed based upon the mathematical formalism of optimal prediction theory and a novel implementation of a filtered harmonic balance solution met ...

The proposed barium strontium titanate (BST) nanodielectric devices will combine some of the best features of bulk and thin-film based tunable dielectrics: low microwave losses, high tunability at high fields, the potential for low operating voltages, and less temperature dependent dielectric response. The miniaturization of devices and reduction of insertion losses requires developments of mater ...

CMU and Magnetics, A Division of Spang and Co. have developed a new high-saturation induction, high-temperature nanocomposite alloy for high-power inductors. This material has FeCo nanocrystals with an A2 or B2 structure embedded in an amorphous matrix. Field annealing resulted in a linear B-H response with a relative permeability of 1400, constant up to fields of 1.2 T. The material was used in ...

Our Phase I program will extend and validate a high-speed engineering transitional model (ETM) using new CUBRC data sets (such as HIFIRE-1) of interest to the Air Force. The ETM is responsive to tunnel noise and wall heating, and predicts the overshoot in heat transfer observed in transitional data. The model solves PDEs for transition onset as well as for an intermittency parameter that blends th ...

Discovery Machine, Inc. is partnered with Pennsylvania State University to produce a best practices capture system that goes beyond the storage and dissemination of lessons learned. The proposed system will leverage warfighters’ specific knowledge as deployable knowledge assets. These knowledge assets will be executable best practices that can be embedded in job aids and training systems. Th ...
