Despite over 100 years of research, decompression sickness (DCS) remains the mission-limiting factor in the design and execution of combat diving operations.Divers may spend over an hour decompressing after spending as little as ten minutes at the target depth.While decompressing, divers are limited in vertical mobility, making then susceptible to detection and threatening their survivability.This ...

To reach the end user, oil and gas production at the wellhead must be transmitted through the country and distributed to a wide range of customers. This logistical system requires natural gas gathering lines, processing facilities, product storage tanks and lots of other equipment. What results is air pollution caused by industry losses during these operations and the use of continuous or intermit ...

We propose a research and development path that leads to the creation of triple-junction, high efficiency (30%, and greater in time) III-V cells on 200mm Si substrates, manufactured in a volume-scalable 200mm silicon manufacturing infrastructure. This combination of efficiency, weight, and cost is not possible with any other technology. Our estimates show that specific weight, cost per W, and sp ...

The development of broadband high-isolation active circulators with simultaneous transmit and receive (STAR) capabilities would enable increased persistence in intelligence, surveillance and reconnaissance (ISR) systems and allow multiple simultaneous radar modes including SAR, GMTI and AMTI for global and local multifunction and multi-task operations. Previous works in MMIC active circulators dem ...

Imaging sensors are a crucial component of modern defense. The ideal sensor has acute visual sensing capabilities and communicates instantly when threats are identified. It should also have night vision capabilities and cover a broadband spectral range including near ultraviolet and infrared. A robotic broadband night vision camera is highly desirable. Such a robotic broadband low-light-level came ...

There continues to be a need for production of fuel-grade ethanol from agricultural sources. The Federal Government is actively looking for biomass renewable feed stocks for enhancing gasoline and reducing our dependence on foreign oil. Ethanol from agricultural sources has many advantages including development of fuel independence, and ethanol has significant value as an oxygenate and octane im ...

We propose to develop a means of combining unit-level and entity-level combat simulations that combines the best features of both and avoids the problems and overhead of multi-resolution simulations and inter-level interactions. The essential idea, which will be elaborated in the following sections, is to develop new alternative aggregate-level algorithms for key combat phenomenology (moving, sen ...

There continues to be a need for the production of fuel-grade ethanol from agricultural sources. The Federal Government is actively looking for biomass renewable feed stocks for enhancing gasoline and reducing our dependence on foreign oil. Ethanol from agricultural sources has many advantages, including fuel independence and its significant value as an oxygenate and octane improver. Unlike gas ...

"Current man portable antennas are heavy, rigid, telescoping or umbrella like contraptions, which limit the mobility and speed of a deployed unit. We propose to improve the weight, storage size, and ease of deployment of a portable antenna through the useof electronic textiles as described in this proposal. Planar antennas have been manufactured on thin films and rolled into position, however a ri ...

There is a recognized need for more effective and economical treatment processes for oily bilge waters. Direct filtration through currently available ultrafiltration (UF) membranes is a mechanically simple process that can provide excellent effluent quality. A limitation to more extensive use of this technology is the tendency of the hydrophilic membranes currently used to foul in the presence of ...
