DSIAC collects and publishes articles related to our technical focus areas on the web to share with the DoD community.
Physiological mechano-acoustic signals, often with frequencies and intensities that are beyond those associated with the audible range, provide information of great clinical utility. Stethoscopes and digital accelerometers in conventional packages can capture some relevant data, but neither is suitable for use in a continuous, wearable mode, and both have shortcomings associated with mechanical transduction of
In a pair of congressional hearings about the Navy”s embattled littoral combat ship program this month, service program managers and oversight officials fielded tough questions about unexpected increases from ship unit costs — from $220 million to $470 million over the course of the program — and concerns about a planned block buy of upgraded
Ford Motor Company and Toyota Motor Company are forming SmartDeviceLink Consortium, a nonprofit organization working to manage an open source software platform with the goal of giving consumers more choice in how they connect and control their smartphone apps on the road. Mazda Motor Corporation, PSA Group, Fuji Heavy Industries Ltd. (FHI) and Suzuki Motor
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
Energetic materials and munitions are used across DoD in mission critical applications such as rockets, missiles, ammunition, and pyrotechnic devices. In these applications, energetic materials and munitions must perform as designed to ensure success in both training and combat operations. There are, however, potential environmental, occupational safety and health risks associated with these materials. Mitigating
Piezoelectric sensors measure changes in pressure, acceleration, temperature, strain or force and are used in a vast array of devices important to everyday life. However, these sensors often can be limited by the “white noise” they detect that can give engineers and health care workers false readings. Now, a University of Missouri College of Engineering
Researchers at the U.S. Naval Research Laboratory (NRL), Optical Sciences Division, in collaboration with the laboratory’s Material Science Division, for the first time have demonstrated successful detection of acoustic emission from cracks in riveted lap joints using a distributed feedback fiber laser-acoustic emission sensor. “An automated, in-situ structural health monitoring (SHM) system, capable of monitoring
Hundreds of military, government and commercial satellites reside today in geosynchronous Earth orbit (GEO) some 22,000 miles (36,000 kilometers) above the Earth—a perch ideal for providing communications, meteorology and national security services, but one so remote as to preclude inspection and diagnosis of malfunctioning components, much less upgrades or repairs. Even fully functional satellites sometimes
A new collaborative effort that connects Navy technical experts with academia is helping to create partnerships that generate real innovation. As a catalyst for developing the Navy’s future workforce, professors and students at universities nationwide are conducting research and development on naval-relevant topics at their campus laboratories. The research takes place through the Naval Engineering
The Army is putting the finishing touches on its robotics and autonomous systems strategy, according to the director of the Army Capabilities Integration Center. The strategy, expected to come out this year, is in “the final stages of editing now,” Lt. Gen. H.R. McMaster told Defense News in an interview at the Association of the
This integrated U.S. Department of Defense (DoD) Additive Manufacturing (AM) Roadmap, released in 2016, provides a foundation and framework for…
New system from MIT can identify how much power is being used by each device in a household. If you want to save on your monthly electric bill and reduce your greenhouse gas emissions at the same time, you might buy a new, energy-efficient refrigerator. Or water heater. Or clothes dryer. But if you can
