The goal of this program is to develop an autonomous, hover-capable, flying robot with an onboard chemical sensor chip for chemical surveillance and environmental monitoring. The key capabilities of this integrated system will be, in order of priority: 1. Real-time chemical sensing and data transfer to a base station. The final platform will detect and identify airborne chemicals using the Mole ...

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...

Our Phase I work focused on improving modeling and simulations so that the impact of autonomous systems in the battlespace could be better understood. As we have trained our attention on Phase II, it has become increasingly clear that the work we are doing to improve the modeling and simulation of autonomous systems also provides significant leverage for the development of the intelligent behavior ...

Automatic speech recognition (ASR) technology is in wide use today and has been successfully integrated into a number of applications. Although there are also many potential applications for automatic speaker identification (SID), SID accuracy rates are generally not sufficient for widespread use in practical applications. For high accuracy ASR and SID, the microphone must be located near the talk ...

We propose a platform for aerial environmental monitoring based on the integration of two advanced technologies for the first time: a lightweight, flying robotic platform capable of hovering and swarming, and a compact, low-power chemical sensor platform called the Molecular Property Spectrometer (MPS): a robust, low-cost, silicon-chip-based micro-electro-mechanical system (MEMS) that has been use ...

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.

The proposed research program aims to develop a physics-based identification, modeling and management infrastructure for aeroelastic limit-cycle oscillations. This infrastructure will be built upon high fidelity state-of-the-art theoretical/computational methods as validated and verified by available experimental data bases, and will include (1) rapid flutter boundary determination for a wide ran ...
