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.

ABSTRACT: The objective of this proposal is to develop efficient sensitivity analysis methods based on adjoint techniques for multi-disciplinary time-dependent problems. The approach is based on the discrete adjoint, which is derived and implemented on a software component basis, with the various multidisciplinary software components being linked together through a Python interface, thus preservi ...

ABSTRACT: Our objective is to develop a vision system for a micro air vehicle (MAV) or other robotic system that allows it to operate in extremely low light levels, including in zero light conditions and without reliance on GPS. We propose building two systems. The first system will operate primarily in the visible and NIR domain and utilize silicon based photoreceptor circuits. This system will ...

Gas turbine combustion plays an important role in a range of Army systems critical to fulfilling the Armys strategic mission. Since high-performance gas turbine propulsion systems operate under highly turbulent high-pressure flow conditions, reliable computational design support tools are used to supplement expensive experimental and flight test programs. In order to provide the desired predictive ...

This Phase I Small Business Technology Transfer program will simulate and demonstrate the feasibility of a Spin-torque microwave diode spectrograph for real-time determination and monitoring of incident microwave signals. The microwave detection will be performed by a bandwidth encompassing parallel array of nano-patterned magnetic tunnel junctions (MTJs). When an ac current of microwave frequency ...

There are many challenges in creating Air Force systems that are resilient against cyber threats. The cyber environment and its threats are highly dynamic, requiring practices and training to be dynamic as well. Cyber threats must be considered during th...
