Electromagnetic launchers or rail guns are a key component of the Navy’s all-electric ship of the future, but they lack the durability required for repeated firings. TDA Research and the University of Nevada, Reno (UNR) are developing a tough, durable and conductive refractory metal coating that will protect the copper alloy conductors (rails) from the extreme heat and wear conditions inside the ...

The objective of this research is to advance technologies for accurately and reliably characterizing the distributed fields within Naval aircraft and the associated currents on avionic systems and their interconnecting cables in the operational electromagnetic (EM) environment. This includes computing the fields and currents within aircraft cockpits, cabins and equipment bays at/near metallic wall ...

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 ...

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 ...

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 ...

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 ...

ABSTRACT: Adversarial installations, such as those housing the means for nuclear weapons production, are increasingly being constructed in heavily fortified locations and often using ultra high performance concrete (UHPC) as the construction material. As such, the U.S. Air Force has considerable interest in further developments of ultra high performance concrete (UHPC) to maintain an advantage o ...

ABSTRACT: Ultra-high performance concrete (UHPC) materials with outstanding material properties offer significant promise to transform infrastructure design and service life. Evolution of UHPC into a mainstream construction material would benefit from the resolution of issues relevant to the restrictive selections of finer aggregates/fillers, large heat of hydration and thermal stresses, high aut ...

ABSTRACT: The purpose of this STTR project is to develop a mathematical tool to simulate EM scattering in a cluttered environment. The main sources of clutter included are periodic scattering from windmills, reflections from fixed topography and effects due to varying atmospheric properties. BENEFIT: Increase radar capability to detect targets over wind farms.

ABSTRACT: Feature extraction and target recognition suffer from a lack of a reliable model for both exploitable target features and the electromagnetic signature they possess. Signature data are often hard to interpret and invert to recover the target robustly. Bayesian learning approaches to statistical pattern recognition are based on the use of training sets of inputs and outputs, a data mode ...
