The airborne network suffers from the limitations of highly constrained network capacity due to wireless link communication and intermittent connectivity among platforms. Information coding theory is a very new technology that is initially proposed for computer networks in 2001 and for ad hoc networks in 2006. The recent study shows it is able to increase the network capacity for mobile network to ...

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 ...

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 ...

Gradient Technology in conjunction with Professor M. Hillmyer of the Department of Chemistry at the University of Minnesota proposed to develop advanced technology to recover and convert the explosive and urethane binder found in plastic bonded explosives. This technology provides a unique reclamation, recovery, and reuse opportunity for dramatically reducing the disposal cost of technology munit ...

Epitaxial growth of non-equilibrium thin-film structures, which have high quality and abrupt interfaces, is still the main challenge that limits many material systems for applications in semiconductor devices. In this STTR Phase II program, SVT Associates (SVTA) in collaboration with the University of Minnesota (UMN) will develop a new RF plasma light-mass ion source, compatible with the low-pres ...

Dramatic differences in the diffusivities of the constituents of novel thin film materials and structures limit material perfection under far from equilibrium growth conditions. We will develop a new light-mass ion source, compatible with the low pressurerequirements of molecular beam epitaxy (MBE), to provide selective enhancement of the motion of surface atoms. Helium or hydrogen ions incident ...

This Phase I STTR project addresses the development of novel Zinc Oxide-based spintronic devices. The spintronic devices will find widespread application in civilian and military markets offering new generation of transistors, lasers and integrated magnetic sensors. The objective of the Phase I effort is to explore novel doping schemes to achieve room temperature ferromagnetism in ZnMgO materials ...

Avalanche photodiodes (APDs) are the detector of choice for low noise, high speed, high sensitivity photodetectors. Applications in the mid-IR (3-5 micron) include optical trace gas detection, LADAR, quantum cryptography and targeting countermeasures. Currently there are no commercially available APDs operating in this wavelength range. To address this need, this Phase I program will investigat ...

The purpose of this Phase I study is to develop quantum cascade laser (QCL) with terahertz (THz) emission. Terahertz photons have energies which lie in the regime between optical photons and high frequency radio waves and have many important commercial and military applications. In the QCL, quantum wells (QWs) and injection layers are grown in a III-V semiconductor superlattice. The QWs and barr ...
