Presently the missile defense systems are using a reactive and program-centric framework for assessing industrial base risk. The Phase I effort focused on developing a wide and deep network algorithm using Industrial Product-Support Vendor (IPV) Gen II program for predicting the probability of failure. The proposed Phase II effort leverages the Phase I work and will focus on three main goals:(1) I ...

Missile flight test telemetry has been performed at S band (2200 2395 MHz) since the 1960s. In 2007, Department of Defense test ranges acquired access to new C-band frequency ranges (4400 4950 and 5091 5150 MHz). While these new bands offer a substantial increase in the total bandwidth available for flight test telemetry, traditional S-band operations will continue for many years, due in part ...

Based on the results of our Phase I work, one significant barrier to optimizing battery performance lies in understanding the relationship between bulk solids and particle flow properties and the flow into the die. Our hypothesis: an increase in quality batteries production can be achieved if powder preparation process can be optimized and the die filling process controlled. We feel that control o ...

ABSTRACT: During Phase 1 the technical feasibility of the Extended-Range Atmospheric Sensing Suite (ERASS) which includes a set of sensors at three different wavelengths (0.53, 1.06, and 1.55 microns), capable of operating in strong-scintillation conditions over long (>100 km) propagation paths and providing both near and far-field measurements of major atmospheric turbulence, laser beam and imag ...

Antimony containing III-V semiconducting compounds are particularly attractive for the fabrication of a wide variety of electronic and optoelectronic devices such as photo detectors operating in the long wave infrared wavelength (12-32µm) range. The production of epi quality GaSb wafers still remains one of the important problems for rapid commercialization of GaSb devices. In Phase I effort, we ...

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 EAS will be deployed by an LBS-UUV to conduct Naval Oceanographic Surveys in shallow water. The unit will consist of a housing containing a projector, a programmable power amplifier assembly, and a battery pack. The EAS projector will be designed to maximize the percentage of energy projected in the direction of the projector's face. The unit will sit with the projector face-down on the ocean ...

Evidence-based guidelines derived from the learning sciences literature can be applied to training-requirements decisions. However, accessing the state-of-the-art in the learning sciences and applying its lessons to specific training design and analysis questions can be difficult, especially for those not already familiar with the learning sciences. ARCHIMEDES, the software tool proposed in this e ...

This Small Business Technology Transfer program will develop a spectroscopic polarimeter-on-a-chip using novel plasmonic resonant cavities sensitive to linear polarization over a narrow wavelength range. Spectral selection will be possible through geometric scaling, with this work concentrating on the visible to near infrared wavelength band. Dielectric gratings with subwavelength period will act ...

The objective of this proposal is to develop advanced radiation transport modeling techniques that accurately and efficiently treat transport in media having widely varying optical properties; in particular, hot gases and plasmas with optical depths ranging from the optically thin to the optically thick regimes. We will develop a hybrid diffusion-Monte Carlo (HDMC) model that efficiently transpor ...
