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 ...

The objective of the proposed effort is to develop a systematic approach for building reduced-order models (nonlinear coupled finite-degree-of-freedom equations) capable of reliably modeling and predicting limit cycle oscillations (LCOs) and using these models in LCO management procedures. The models will be developed by combining (a) physical observations from ground vibration, wind tunnel, and ...

We propose to embed quantum dots in resonant optical cavities to sharpen their spectral respone and provide a mechanism to spatially vary it across an infrared detector array. This project will combine the self-assembled-quantum-dot epitaxy expertise of Professor Towe's group at Carnegie Mellon University with the infrared focal plane array design, fabrication, and test expertise of QmagiQ. Phas ...

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 ...
