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 ...

Empirical-based mathematical framework and computer algorithms, for representing human perception and cognition processes and limitations, which influence the recognition of salient information about rapidly changing events.

Due to the limited amount of rhenium present in the earths crust (approximately 1-2 part per billion) there is a significant benefit to be realized in recovering for reuse the rhenium from scrap material, spent catalysts, or end-of-life superalloys. Rhenium is found in molybdenum-copper porphyry deposits. If rhenium is present in ore that is processed, it will show up in the resulting molybdenum ...

The benefits of greater power and efficiency are offered by using turbochargers and superchargers for small UAS propulsion systems which including rotary, piston, and other developing engines. Present day UASs suffer performance losses upon takeoff and at altitude. Therefore, the need for improved, light weight turbo and superchargers which eliminate the use of oil lubrication for the bearing sy ...

ABSTRACT:Sophisticated methods for infiltrating and compromising computer systems have continuously demonstrated their ability to defeat current operating system and network defenses. Computing assets such as the BIOS, hardware device drivers, and COTS hardware from non-trusted supply chains have been proven to include malware and/or Trojan horse applications. These subversive software programs pr ...

The proposed effort will result in an "universal" fan noise cancellation system for use with high performance fans used extensively in defense applications including auxiliary power unit (APU) applications. Fans are a critical noise source that impact the audible detection range of the platform. The importance of the fan noise for detection continues to increase as other technology improvements ...

As analysts and operators move from data to insights, tools are needed for supervisory control, command and control, and intelligence analysis. Intelligence, Surveillance, and Reconnaissance (ISR) requires the ability to navigate and interpret mounds of data to produce actionable decisions. Through the Urban Telepresence program, the Air Force Research Laboratory (AFRL) is redefining a concept of ...

Cyber assets usually support missions with different priorities, and the objective and systematic measurement of their resilience and criticality may play a major role in mission success. One basic requirement for achieving mission success and mitigating the adverse impact of advanced threats is to measure the defense and resilience effectiveness of individual and collective cyber assets. Therefor ...

To deal with the increasingly complex, dynamic and unpredictable operational environments of the 21st century, unmanned and autonomous system, sensor, and vehicle technologies are being expanded and improved. For example, unmanned air, ground, and maritime systems provide an expanding set of capabilities, such as intelligence, detection, security, targeting, and strike, while reducing the risk to ...
