AlInGaN-based heterostructures have demonstrated unmatched versatility in optical and electronic applications. In particular, AlGaN/GaN high electron mobility transistors (HEMTs) are the leading candidates for realizing ultra-high frequency, low-noiseand high-power amplifiers. The addition of indium to the composition of these HEMTs is expected to dramatically improve their performance. We prop ...

Fiber optical transmission is increasingly applied to computer network, secure telecommunication systems, military aircraft, and even in missile guidance systems. 1300 nm vertical cavity surface-emitting lasers (VCSEL) are becoming a prefered technologyfor transceivers in short- and medium-haul, enterprise and metro data network. There is significant interest in using diluted nitride GaInNAs as ac ...

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 ...

This program is to develop multi-layered,light weight armor alloys systems that offer improved fragmentation and armor piercing performance as compared to any other monolithic structures. Such alloys and laminated configuration will be developed by utilizing advanced computational techniques to assist in the development of complimentary alloys that would provide an optimal combination of hardness ...

Technical Abstract Current economic conditions and an aging population are increasing the strain on the Medicaid program, which is the main funding source for long-term skilled nursing care. In 2008, Medicaid spending for long-term care was $99.9 billion and growing at a rate of 8.6% annually. Given that the population of persons over 65 years of age is expected to grow from 35 million in the ye ...

Freeform optical surfaces offer advantages over axisymmetric surfaces in the ability to reduce optical sizes, increase performance and reduce aberrations. However, the description, fabrication and metrology of these surfaces can be difficult and costly, prohibiting their ability to achieve their full potential. Fabrication of these surfaces can be difficult since they are not axisymmetric and have ...
