During altitude-induced hypoxia, operator cognitive and physical capacity degrades, compromising individual and team performance. Cognitive degradation is linked to falling brain energy levels, increased reliance on anaerobic energy production and lactate accumulation. Ketones are the evolutionary alternative substrate to glucose for brain metabolic requirements; previous studies demonstrated that ...

Special OperationsForces (SOF)are an integral aspect of the US military. SOF operators are among the most elite and highly qualified individuals in the U.S.military. As such, extraordinary physical and mental demands are placed upon them to excel in extreme environments for extended periods of time. This unrelenting cycle of combat deployments and intense pre-deployment training shortens the funct ...

Pressure gain combustion has the potential to significantly improve the specific fuel consumption for gas turbine engines by realizing a pressure rise through the combustor as opposed to a pressure drop. One drawback to this form of combustion is the cycl

Cost effective semiconductor processing tools that enable the high-resolution nano-fabrication of low-volume electronics are needed by the DOD. The printing of ultra-fine gratings on silicon wafers using interference immersion lithography is envisaged as a first maskless process step in the fabrication of advanced application specific integrated circuits. Next generation interference immersion lit ...

This proposal is to develop a new system for Recognition of Communities and Heterogeneous Analysis of Group Interactions and Dynamics (RC-HAGID) for Social Media Forecasting. Social media enables individuals and groups to quickly coordinate, recruit and direct people to take action in support of a particular objective. This includes terrorist groups and criminal organizations. Accordingly, for ...

Federal Aviation Administration Advisory Circular 20-107B provides guidance on the achievement of compliance with Title 14 of the Code of Federal Regulations regarding airworthiness type certification requirements for composite aircraft structures necessi

Pressure gain combustion (PGC) offers means to a more efficient energy use in propulsion and power generation devices. Integrating PGC concepts in gas turbine engines often results in highly unsteady flow conditions at turbine inlet. Further, the backpres

Carbon fiber reinforced polymer composite materials are light and strong, however the development of composite aerostructures has been expensive and slow. Custom tooling is required for each part produced, significant capital investment is required to win
