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 ...

Thermally induced fatigue and residual stress introduced during fabrication are sources of failure in microelectronics, which raises reliability concerns for MDA and its system integrators. CFDRC has teamed with experts in the reliability of microelectronics packaging to develop a physics based modeling and testing protocol to correlate material properties and thermal loading conditions to stress ...

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 ...

Helmeted navy divers are exposed to high levels of noise from self-generated mechanisms, such as regulator exhaust, and external sources, such as underwater tool-generated noise. Noise exposure limits can be easily exceeded especially if effective communications through helmet-mounted speakers is required. A multi-faceted approach is proposed to reduce self-generated noise as well as overall helme ...

CompuTherm, LLC proposes to develop innovative new generation software based on the CALPHAD method. This new software, named Pandat-Pro, will be built upon CompuTherms current Pandat software. The significant advances of Pandat-Pro are: (1) Bayesian analysis will be introduced to perform error analysis for both the optimized model parameters and the simulated properties; (2) a database management ...

EO/IR sensors can provide high spatial resolution images using multiple frequency bands ranging from the visible to mid-wave IR. EO/IR sensors have been very successful for terrain imaging from subsonic aircraft and from satellites. Imaging using these platforms has been studied extensively. EO/IR sensors can provide high spatial resolution images using multiple frequency bands ranging from the v ...

Sensor development researchers and engineers have perpetually sought novel methods to reduce sensor size and improve performance. Continued miniaturization of sensors through micromachining has enabled novel applications and introduced new paradigms for engineered systems to interact with the world. The challenge has always been to improve performance while continually reducing size. In the curren ...

Random numbers are essential for a growing number of modern applications. As computer speed and communications bandwidth have increased the potential for practical streaming cipher and large-scale Monte Carlo simulations have become technologically feasible. For these and other applications, ultrafast random number generators are essential. This is intuitively clear. Additionally, however, the ide ...

There is an unmet demand for ultra-low-power, ultra-compact and low-cost radios to address emerging sensing and communication needs for military and commercial applications such as IoT/IoE. To overcome the limitations in existing bulky and power hungry radios, we propose a disruptive solution by integration of a nano-scaled THz transceiver, on-chip antenna, and energy harvesting circuits in a form ...
