The objective of the work described in this proposal is to aid in the advancement of Mo-Si-B alloys for use in high temperature applications such as hot gas stream components in turbine engines. Such alloys are being characterized for their monotonic tensile properties in tension and compression as well for their creep resistance. Likewise, multiphase Mo-Si-B alloys have been studied in terms of m ...

Marine mammals like bottlenose dolphins are maintained by US Navy's Marine Mammal Program to protect harbors and detect underwater mines. The maintenance and betterment of health of these dolphins in captivity is a priority in order to improve the fitness and readiness of these animals for defense missions. Accacia International proposes to develop probiotic pharmaceuticals to treat and preve ...

Complex software systems are typically developed by disparate engineering teams working concurrently. At the same time, software requirements are frequently dynamic, evolving even during active development cycles. Discrepancies between how software is defined and how it is implemented at the modular level can cascade into critical system errors when modules are integrated. More troubling is that i ...

Autonomous systems acquire massive amounts of sensor and communications data over the course of their potentially lengthy missions. Ideally, such systems would incorporate current and historical data into their decision making processes to generalize from experience and avoid repetitive errors. However, the sheer quantity of data gathered can make storage and processing of an unfiltered data strea ...

Autonomous systems continue to be outfitted with larger amounts of sensors that are capable of collecting extremely large amounts of data over the course of a mission. Even autonomous systems with high storage capacities can run into storage limitations when burdened with large amounts of sensor data over long mission durations. This proposal will develop a Learning-based Approach for Relevant Dat ...

Thermophotovoltaic (TPV) energy conversion produces electrical power from heat energy using, in its most basic form, a thermal emitter and a photovoltaic converter. Since these systems typically have no or few moving parts, they provide a long term maintenance-free power generation. Key factors affecting performance include matching the emitter spectrum more precisely to the conversion characteris ...

As strontium and other alkaline-earth metals become increasingly attractive for ultracold-atom applications, there is a growing need to develop compact, robust systems for cooling, trapping, and studying these elements. In this proposal, ColdQuanta will team with Dr. Jun Ye at JILA and the University of Colorado at Boulder to develop a portable, turn-key system that can produce, utilize, and optic ...

Vescent Photonics proposes to develop a compact laser system and integrate it with a cold-atom micro primary standard developed under the DARPA IMPACT program. In phase I we will investigate performance enhancements resulting from immobilizing the cold-atom sample with an optical lattice formed from an optical field whose wavelength is chosen to minimize the differential light shifts between the s ...

This research seeks to develop a method of developing solid-state power amplifiers that operate at 300 Volts, achieve 100 Watt output and greater than 90% efficiency at 1 GHz with 10% bandwidths. We will seek to demonstrate switch-mode amplifiers that use a novel gate design with Gallium Nitride forming the basis for solid state power amplification.

US troops and equipment are increasingly at risk for irradiation by lasers, whether it be from enemy targeting and ranging systems, designators, or high-energy lasers as weapons themselves. Countering the threat requires detection of the incident laser radiation, the direction from which it is originating, and characterization of its wavelength and temporal profile. Nanohmics Inc., in partnership ...
