The unique electronic properties of periodically-arranged indium arsenide/gallium antimonide (InAs/GaSb) mesas in the type-II strained layer superlattices (SLS) make them a superior alternative to the conventional HgCdTe sensors for longwave infrared focal plane array (LWIR FPA) detectors. However, despite the highly promising quantum structures of SLS, its performance is currently limited by high ...

Advanced lightweight ablative materials are needed to provide additional performance gains for next-generation ballistic missile defense system (BMDS) interceptors. The interceptor third stage, in particular, will benefit substantially from a reduction in inert weight, which enables increased missile stack velocity. Operational targets for the interceptor third-stage rocket motor (TSRM), and for o ...

Uncertainty quantification (UQ) can be performed with existing MDA M&S tools if efficient algorithms are developed and deployed. OptTek proposes to explore innovative methods and algorithms to 1) quantify output variation from all input uncertainties providing distributional information and extreme value identification, 2) isolate output variation from individual input uncertainties and from input ...

San Diego Composites (SDC) is developing a toroidal composite overwrap pressure vessel (COPV) for use on next generation propulsion systems. A development effort sought to optimize the electron beam welding process parameters to reduce weld integrity sensitivity to poor fit up conditions when butt-welding the thin titanium liners integral to these composite overwrapped tanks. Results from this dev ...

The proliferation of sensitive DNA-based assays for detecting the presence of specific harmful, toxic or invasive organisms, as well as the simple reagent and instrumentation requirements for these assays has made widespread and more frequent testing for these different organisms possible. However, a frequent problem with such assays is the lack of available, well-quantified positive control stand ...

Ensuring the health of coastal marine ecosystems has emerged as one of the primary environmental concerns of this century. Frequent monitoring of water quality is required to establish baseline levels, allow identification of anomalies, and enable early detection of problems. Citizen science programs have been shown to be a highly effective method of monitoring water quality. Creare proposes to de ...

Paralytic shellfish poisoning (PSP) due to consumption of contaminated shellfish is an increasing problem is the coastal waters of the United States, particularly in New England and the Pacific Ocean. The symptoms of PSP include vomiting, diarrhea, shortness of breath, confusion, and loss of coordination in both marine animals and humans. In severe cases, PSP toxins can cause respiratory failure a ...

The Space weather-based position error maps for TEC-On-Line (SpoT-On) project will use GPS=GNSS based TEC data, integrated into the Global Assimilation of Ionospheric Measurements (GAIM) operational system at the Utah State University Space Weather Center to product improved TEC position correction maps. These will be publicly and globally accessible. A result is that agencies, industry and consum ...

Commercial marine aquaculture operators face many operational hazards including disease, predators, husbandry operations, and environmental changes. Most of theses risks are only identified with constant surveillance and physical presence at a farm site. However, human observation of risk factors is expensive, slow, and sometimes ineffective. Sensors are available to monitor individual environment ...

Commercially available unmanned aircraft systems (UASs) are not well designed to meet requirements for many atmospheric measurement applications, including deployment from ships, long endurance, and low cost. Multi-rotor UASs have recently gained popularity as a lowcost platform use in measurement and monitoring applications, but these systems have limited endurance and payload capabilities. Exist ...
