DSIAC collects and publishes articles related to our technical focus areas on the web to share with the DoD community.
A new, first-of-its-kind-worldwide research capability will help unravel the mysteries of material behavior at extreme conditions and short time scales in support of the National Nuclear Security Administration’s (NNSA’s) vital national security missions. NNSA, the Department of Energy’s (DOE’s) Argonne National Laboratory and Washington State University (WSU) will dedicate the new Dynamic Compression Sector (DCS)
Breaking things can help scientists answer both the most elemental and the most everyday questions. Humans spend a lot of time creating things—this drives a huge amount of our lives, economically and personally—and we are always in a fight to keep them from breaking down. Houses, roads, cars. Power lines and bridges. Solar cells and
The Pentagon is looking for the next wave in warfighting technologies, inviting industry to offer ideas in key areas, such as dealing with the electromagnetic spectrum and ways to manage the flood of data collected by its growing number of sensors. The Defense Advanced Research Projects Agency is staging a Proposer’s Day Sept. 20 to
Researchers at North Carolina State University have developed a new type of inverter device with greater efficiency in a smaller, lighter package – which should improve the fuel-efficiency and range of hybrid and electric vehicles. Electric and hybrid vehicles rely on inverters to ensure that enough electricity is conveyed from the battery to the motor
General Motors and the U.S. Army Tank Automotive Research, Development and Engineering Center will reveal a Chevrolet Colorado-based fuel cell electric vehicle in October at the fall meeting of the Association of the United States Army in Washington. The vehicle is being developed under an agreement signed in 2015 between TARDEC and GM. The collaboration
Directed-energy weapons systems could provide efficient, cost-effective countermeasures in an age of drones and other airborne threats. Recent scientific and engineering breakthroughs are bringing these systems closer to deployment. Long before George Lucas conceived of the Death Star with its super laser focused on Alderaan, even before H.G. Wells wrote War of the Worlds with
A newly discovered optical vortex forms a ring around many intense laser pulses but was never noticed before. In a typical optical vortex, light waves twist around a dark line, or hole, through the center of a light beam. Researchers have now uncovered an entirely different type of optical vortex that forms a ring, or
One of the efforts the Navy is undertaking under the guise of the third offset strategy — commonly described as undercutting adversarial advances through human-machine teaming — is a recently established initiative to examine interoperability between the service’s sensors, platforms and weapons. Task Force Netted Navy, which began in May 2016, is all about maximizing
Machine vibration often originates with rotating driveline components such as rotors, gears, bearings, and fans. Such vibration is the source of unwanted noise and can be destructive to the machine. The vibration ring is a mechanism that provides an indirect damping effect, and is rigid enough to be mounted within the driveline. The mechanical structure
Four-star Admiral Greenert, stating the Navy’s foremost priority before a distinguished audience of military, government, academia, and industry representatives in Washington, D.C. at the 2015 Naval Future Force Science and Technology Expo, repeated the enduring reality that, “Probably the biggest vulnerability of a ship is its magazine, because that’s where all the explosives are.” But
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
The Navy”s new “first-of-its-kind” stealthy destroyer will soon go to San Diego, Calif., where it will go through what’s called “ship activation” – a process of integrating the major systems and technologies on the ship leading up to an eventual live-fire exercise of its guns and missiles. As part of this process, the Navy will
