In Phase II, based on the Phase I success, we propose to research further enabling optimizations for a wider range of sensor applications than in Phase I. We will also implement the key optimizations to SAR found in Phase I within the SANE high-productivity array language and automatic parallelization tool chain. These optimizations have a wide application domain within sensor applications and bey ...

This Phase I program is focused on enhancement of the performance of MgZnO based solar blind detectors. MgZnO alloys have superior optoelectronic properties with bandgaps suitable for solar blind detection. Issues related to doping and miscibility will be addressed. This will involve the use of advanced MOCVD and MBE growth techniques and consideration of both Schottky and p-n junction devices. No ...

Advanced ordnance and propulsion systems utillize materials, such as RDX and HMX, that provide good performance but cannot meet todays more stringent safety and environmental requirements. Unfortunately, in newer compounds created to replace them, the performance falls with the sensitivity. The ORBITEC team proposes the development of new energetic materials that will be both high performance and ...

HYPRES, in collaboration with University of Massachusetts, proposes an energy-efficient hybrid-temperature-heterogeneous-technology (HTHT) digital data link for interfacing 4K superconductor electronics with room-temperature electronics. Comprising several stages of cryogenic SiGe amplifiers at different temperatures, followed by equalization techniques, this data link will be designed to minimize ...

In recent years, the need for highly reliable, durable and non-intrusive systems for monitoring the health condition of naval structures becomes more and more recognized. Of particular importance is the condition based maintenance of Navy rotating machinery (motors, generators, pumps, gear systems, etc.). Such Structural Health Monitoring (SHM) systems should be able to detect failures in their ea ...

ABSTRACT: An experimental and computational effort is proposed to develop a data-driven experimentally-validated framework for analysis of plastically bonded energetic materials at meso and micro scales. A unique data-mining strategy and model reduction technology based on thermodynamics and manifold learning techniques and on nonlocal dispersive reduced order model will be devised. Reduced order ...

The technical objectives of this proposal are: 1) Design a metal/semiconductor grating-based (i.e., substrate-emitting) Grating-Coupled Surface-Emitting Distributed Feedback Quantum Cascade Laser (GCSE-DFB QCL) emitting at 4.6 microns with high beam quality; and 2) Demonstrate a GCSE-DFB QCL emitting at 4.6 microns with single-lobe-beam operation and high beam quality, under CW operation. It is th ...

The objective of this proposal is to demonstrate a generic package that provides high vacuum, temperature control and vibration isolation for a wide range of high performance (tactical and navigation grade) micromachined inertial sensors. Inertial sensors (accelerometers and gyroscopes) are now widely used in consumer and industrial applications. However, for high performance navigation and target ...

Pressure gain combustion has the potential to significantly improve the specific fuel consumption for gas turbine engines by realizing a pressure rise through the combustor as opposed to a pressure drop. One drawback to this form of combustion is the cycl

Software continues to be a weak link in our critical systems. A prudent operator should employ a defense-in-depth strategy whereby"safe"systems are still monitored to detect breaches and respond to them. Unfortunately, such monitoring is challenging in practice, since there is no universal pattern that characterizes misbehaving software. We will capture an application"s intended behavior as it is ...
