Industrial facilities such as refineries and chemical processing plants rely heavily on the use of compressed air for a variety of purposes, such as actuating valves as materials flow through vessels, reactors, and pipes. Compressed air is also used in these facilities to purge enclosures housing electronic equipment of hazardous vapors. The financial and safety risks associated with failure or malfunction of these pneumatic devices are substantial.

As a Coast Guard aviator, Howard Baker has experienced firsthand the complexity of reporting his in-air position to command centers on the ground, especially during crises or natural disasters involving multiple aircraft carrying out multiple operations. The current system relies mainly on periodic radio calls between aviators in the air and command centers.
The roots of Bryant Tong's final Systems Engineering program project lie on a 30-mile stretch of I-495, where the modeling and simulation analyst spent many hours each morning and evening for four years, commuting between his home in Silver Spring, Maryland, and a former position in Chantilly, Virginia.
The United States has one of the lowest voter-turnout rates of any of the world's developed countries.
