The integration of physical and cyber systems have dramatically increased the vulnerability and the attack surface of cyber physical systems. The most common architecture to achieve the monitoring and control of the critical infrastructures is the Supervisory Control and Data Acquisition (SCADA) systems. As SCADA systems become interconnected with Internet resources and services, they become easy ...

A critical step in the extraction of elements from ore, especially rare earth elements that are found in complex minerals, is separation. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then ca ...

This Phase I SBIR OSD project proposes the development and testing of a porous metal anode-supported intermediate-temperature solid oxide fuel cell (PMS-IT-SOFC) that exhibits high electrochemical efficiency, high degree of fuel utilization (reformed JP-8, diesel, or dodecane), and low operating temperature characteristics intended for high efficiency, logistic-fueled propulsion and power systems ...

The recent increase in cyber attacks against United States critical assets has greatly expanded the need for effective cyber defenses. Human cyber analysts are an essential element in these efforts. Information overload and a concomitant lack of comprehensive cyber situation awareness are common problems that hamper the effectiveness of analysis. Systems that can carry out human-in-the-loop simula ...

"This DoD Small Business Innovation Research Phase I project proposes an innovative fullerene-polymer based electrolyte for PEM fuel cells. A limitation of the commercially available perfluorinated sulfonic acid electrolytes is that they are highlydependent on humidification and do not function well above 100¿C in H2-PEM fuel cells under normal conditions. The poisoning of the CO is also a severe ...

Development is proposed of a new, rotary form of Stirling cryocooler which offers longer operating life and much lower vibration than reciprocating forms of cryocoolers. The proposed machine has fewer moving parts to wear and can be completely balanced to eliminate vibration in all planes by simple counterweights on the shaft, which is not possible in reciprocating machines. The rotary desi ...

This proposal describes an innovative coarse-to-fine approach to the detection of militarily relevant changes in electrooptical remotely sensed imagery. Our approach is based on the use of a generalized cross-image modeling technique to act as a focus-of-attention mechanism, and graph monomorphism finding algorithms for object-level reasoning. The focus-of-attention algorithms are robust with re ...

Acoustic transducers have found wide applications ranging from Navy sonar systems to civilian underwater imaging. Piezoelectric materials perform an essential role of electromechanical energy conversion in such devices. Current piezoelectric materials can not satisfy the increasing requirement of the sensitivities of acoustic transducers for both military and civillian applications. This progra ...

The world wide communications infrastructure is undergoing dramatic revision, with optic fiber providing virtually limitless bandwidth, and wireless communication connecting increasingly mobile users to that fiber backbone. However, cost-effective evolution to an information-rich society will require strong standardization of wireless communication technology. The United States gave birth to the ...
