We propose the development of a system for measuring the minority carrier lifetime in strained layer superlattices (SLS). Mid wave infrared (MWIR) and long wave infrared (LWIR) detectors based on SLS technology show promise due to the large and inexpensive focal plane arrays that can be fabricated. The devices are held back though, by excessive dark current, which is related to a poor minority car ...

The US Navy is undertaking a Total Force Transformation to develop a more agile, deployable, and capable force to meet the challenges of 21st century conflicts. The adaptive expertise required by the Total Force demands innovative and evidence-based approaches to instruction, training, and assessment that enable the development of both routine and adaptive skills. Given the costs of developing tra ...

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. Sinmat Inc. proposes a ...

The rapid ascent and adoption of social media as the dominant form of communication has led to significant analysis challenges. In particular, there is a gap in theoretically informed methods to analyze data mined and collected from social media. One primary cause of this gap is the lack of fusing structural sources of information (e.g. social network topology) with non-structural sources (message ...

SRICO proposes to combine metamaterial narrowband absorbers and SRICO-proprietary thin film lithium tantalate (TFLT) pyroelectric thermal detectors to produce ultra low cost, size, weight and power (SWaP) room temperature stand-off chemical sensors. Metamaterial narrowband absorber elements will be integrated into the TFLT pyroelectric detector process to provide conversion of radiation to heat, w ...

Genome-scale predictable cellular design and engineering of biomanufacturing systems is the overarching a goal of DARPA's Living Foundry thrust and, if realized, will enable rapid engineering of living biosystems for a broad range of applications in biotechnology and pharmacology. However, constructing living cells with designed genome is not fully automated and is severely limited by inhere ...

An emerging consensus in engineering holds that aleatory uncertainty should be propagated by traditional methods of probability theory but that epistemic uncertainty may require methods that do not confuse incertitude with variability by requiring every possibility be associated with a probability that it occurs. Therefore, although Monte Carlo shells that re-run calculations many times while var ...

A goal of Uncertainty Quantification (UQ) is to use computer simulation of complex systems to make scientifically informed assessments for high-consequence decisions. Because end-to-end empirical data is difficult to obtain for the Ballistic Missile Defense System (BMDS), computer simulation provides the best method for understanding BMDS capabilities against a wide range of threats. Numerica Co ...

The neurocognitive health of U.S. service members plays a vital role in the defense of the United States. It is critical to a service member"s effectiveness, to force readiness, and it is a key component of a service member"s successful reintegration into family life and society following deployment. Increased rates of mild traumatic brain injury (mTBI) and psychological health problems experien ...

OptTek Systems, Inc (OptTek), proposes an affordable, effective UQ capability for both legacy and new BMDS M & S. The OptTek Team includes research institution partner Oak Ridge National Laboratory (ORNL) and subcontractor RTSync Corporation (RTSync). The proposed BMDS M & S UQ capability maximizes insertability into existing and future MDA BMDS M & S-supported Event processes, analysis methods, a ...
