Molecular beam epitaxy has become essential technique to produce high quality materials and complicated structures. Competing with other growth techniques, such as MOCVD, it has demonstrated higher materials quality and better film uniformity. These adva...

Triton is proposing to develop a family of preceramic polymers and polymer formulations that will produce group 4 (Zr and Hf) carbides and carbide/boride mixtures in good yield. The target yield for the program is 60 vol%. The goal is to develop material...

This research is to design, fabricate, and demonstrate scalable and aerospace-quality advanced composite materials using carbon nanotube (CNT)-based yarns and sheets with advanced mechanical properties (>3.5 GPa in tensile strength and >200 GPa in Young...

In this Phase 1 proposal, Vuronyx Technologies in collaboration with Georgia Institute of Technology, Atlanta (GT) intends to fabricate composite panels using high strength and high modulus carbon fibers synthesized from polyacrylonitrile (PAN) precursor...

Automatic target recognition (ATR)the identification of a potential target based on signatures in sensor datais fundamentally a question of information content. While ATR has been studied for decades, it remains a challenge because multifarious tar...

In order to meet future needs for cost-effective high-capacity, secure telemetry systems, communication systems, smart weapons systems, UAVs, satellites, and other DoD platforms, further advances and innovations in digital-to-analog conversion must be achieved to support the migration to higher frequencies and operation in shared spectrum environments. This dictates a requirement for transmitters ...

This Phase-II STTR Proposal first summarizes Phase-I progress on the development of a microelectromechanical-system (MEMS) solid-state shear-stress sensor for high-speed, high-temperature flow applications.A working prototype has been completed and successfully tested in a heritage Mach-5 wind tunnel at The University of Texas at Austin.The fundamentally new device concept has been verified in Pha ...

Physical Sciences Inc. (PSI) and the research group of Professor Richard Osgood at Columbia University propose to develop a compact optical transceiver based on devices fabricated on a complementary metal-oxide semiconductor (CMOS) platform. The recent development of novel integrated structures in silicon including waveguides, resonators, and photodetectors will enable dramatic reductions in size, ...

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 ...
