Fault tree analysis is a useful probability theory-based tool for evaluating a system’s risk and reliability. Typically, fault trees are populated with basic event failure probabilities from a variety of quantitative and qualitative sources. This article presents a new methodology that combines simulation with game theory to populate a fault tree with strictly quantitative probability
Case Western Reserve University, NASA Glenn Research Center and the University of Toledo will serve as “living laboratories” that demonstrate the value of integrating distributed energy sources with the assortment of devices, equipment and other power consumers within buildings and across the grid. The effort begins this month with a one-year award administered by Pacific
A new study, led by Professor Jae Sung Son of Materials Science and Engineering at UNIST has succeeded in developing a new technique that can be used to turn industrial waste heat into electricity for vehicles and other applications. In their study, the team presented a new type of high-performance thermoelectric (TE) materials that possess
This report highlights the Defense Department”s top 10 issues in 2016. During the year, DoD continued to counter terrorism and proceed with missions in the Asia-Pacific region, Europe and Afghanistan. Defense Secretary Ash Carter expanded efforts to build the Force of the Future while seeking new technologies, promoting the well-being of troops and pushing for
Jared Schwede and Daniel Riley completed their Ph.D.s in the department of physics at Stanford University. At Stanford, they were part of a world-leading research group on thermionic energy converters, focusing on a breakthrough solar conversion process based on photon-enhanced thermionic energy conversion, which harvests both photon and heat energy from the sun”s spectrum.

The US Army isn’t counting on airpower in the next war. Without that cover, there won’t be supply drops, recon drones or medevac helicopters picking up your casualties — and you will have casualties. “Land-based forces now are going to have to penetrate denied areas to facilitate air and naval forces. This is the exact
One of the biggest revolutions over the past 15 years of war has been the rise of the drones — remotely piloted vehicles that do everything from conduct air strikes to dismantle roadside bombs. Now, a new generation of drones is coming. Only this time they are autonomous — able to operate on their own
The Marine Corps is moving towards a future in which small dispersed units can protect themselves from incoming enemy drones with laser weapons and from missiles and aircraft with Stinger missiles, with both weapons netted into a detection system and mounted atop Humvees, Joint Light Tactical Vehicles and other combat vehicles. Lt. Gen. Robert Walsh,
Silently, the drone aircraft glides above the arid terrain of New Mexico — until it suddenly pivots out of control and plummets to the ground. Then a mortar round rises from its launcher, arcs high and begins to descend towards its target — only to flare and explode in mid-flight. On the desert floor, on
On a summer’s evening in the sweltering South China Sea, a coastal steamer of nearly 2,000 tons approaches a Vietnamese fishing fleet in the exclusive economic zone of Vietnam, some 150 miles off that nation’s coast. The steamer loiters in the area for an hour or two as night falls. Suddenly from the side of
BAE Systems’ Next Generation Bradley Fighting Vehicle demonstrator is debuting today at the Association of the United States Army (AUSA) annual meeting in Washington, D.C. The concept vehicle features an upgraded chassis that allows for significantly increased underbelly protection, improved force protection for mounted troops, compartmentation of fuel and ordnance, and more space and electrical
Additive manufacturing (AM)—known also as “3D printing”—has exploded into public consciousness over the past several years. Stories and perspectives seem to appear in the popular press and technology blogs on a near daily basis. Enthusiasts tout the prospect for AM to revolutionize manufacturing industries and the markets they serve, while skeptics point to the relatively
