We propose developing a wide area situation awareness (WASA) application for android mobile phones.

Social network analysis is a powerful method for making sense of an increasingly interconnected world. Developing social network analysis tools requires datasets with which to test them, but sharing datasets is problematic because of privacy issues. Initial attempts to anonymize network datasets proved ineffective due to de-anonymization attacks that leveraged publically available information to i ...

Systima is proposing to develop an end-to-end integrated solution to provide a high velocity, Long Range Ram Accelerator Mobile Field Howitzer (LRRAM-FH) system that will dramatically increase velocity and range capabilities over conventional artillery. The ram accelerator launcher will accelerate the projectiles to velocities greater than 2 km/s, which will extend the capability of modern kinetic ...

The purpose of this topic is to develop a pump that can pump two-phase, liquid and vapor mixtures of common refrigerants and heat transfer fluids, without oil lubrication. The challenges of pumping in this regime are well known: Two-phase, liquid-vapor refrigerant mixtures are a mixture of saturated liquid and saturated vapor, by definition meaning that there is zero net positive suction head. M ...

Etrema is developing an acoustic projector that provides broad bandwidth, high source level, directional output, high duty cycle, and high reliability in a compact package. Specific objectives of the Phase II effort are: demonstrate performance of a prototype projector, optimize the full-scale projector design, and demonstrate performance of the full-scale projector. Fabrication and testing of the ...

Traveling sine waves can occur in an aerial refueling hose that result in excessive forces transferred to the receiving aircraft"s refueling probe. These waves can arise from failures in the hose reeling mechanism, high aircraft approach speeds, or other inputs that create excessive hose slack. New concepts will be analyzed that significantly reduce or eliminate these waves, leading to a new innov ...

Probe and drogue air-to-air refueling (AAR) involves extending 70 to 80 feet of hose to allow for receiver engagement. If the receiver engages too fast and/or the hose reel fails to keep tension on the hose, a sine wave will develop. This sine wave can produce overloads on the receiver aircraft probe with catastrophic consequences. AR hoses today are designed to meet the strength and construction ...

We propose to develop techniques and equipment for fully automated retrieval, refueling/ recharging, and relaunch of Aerovel"s Flexrotor. Our method would be suitable for use on a small platform such as a boat in a choppy sea. It would allow the ground-handling cycle to be performed remotely with no manual intervention, and so enable extended missions through remote unattended sites. Planned work ...

We envision a class of miniature robotic aircraft dubbed Flexrotors which offer range, endurance, and economy at levels associated with wing-borne flight, together with capability for hover and VTOL. Such aircraft would use low-disc-loading rotors which must operate efficiently from zero advance ratio in thrust-borne flight, with rotor axis vertical, to high advance ratio in wing-borne cruise, wit ...

Automated techniques for harvesting knowledge from documents will make tasks like intelligence gathering significantly faster and more reliable. Information in documents is often distributed between text and non-textual components, which rely upon each other to create a comprehensive picture of what is being conveyed to the reader. The Friedland Group, working with our partner, The University of R ...
