• New internally cured concrete increases bridge life span

    Concrete is normally made by mixing portland cement with water, sand, and stone. In the curing or hardening process, water helps the concrete mixture gain strength by reacting with the cement. Traditionally, curing is promoted by adding water on top of the bridge deck surface. The new technology for internal curing provides additional water pockets inside the concrete, enhancing the reaction between the cement and water, which adds to strength and durability. This new technology is enabling Indiana to improve bridges in the state with a new “internally cured” high-performance concrete.

  • New bridge construction technologies to shore up U.S. infrastructure

    See video

    Experts agree that there is an urgent need to construct and repair bridges across the United States. Around 70,000 bridges in the country are considered “structurally deficient” by government standards. New technology could help the United States manage its growing, and aging, infrastructure without breaking the bank or levying high taxes on citizens.

  • Military electronic devices disappear into the surroundings after use

    Electronic devices have become necessary for military operations, but it is almost impossible to track and recover every device. At the end of operations, these devices are often found scattered across the battlefield and might be captured by the enemy and repurposed or studied to compromise DoD’s strategic technological advantage. New DARPA program — Vanishing Programmable Resources (VAPR) program — seeks transient electronics, that is, devices which would maintain the current functionality and ruggedness of conventional electronics, but, when triggered, be able to degrade partially or completely into their surroundings.

  • Biometric workshop studied voice, dental, oral standards

    The National Institute of Standards and Technology (NIST) hosted a workshop to discuss proposed supplements to the biometric data format standard that support voice recognition, dental and oral data, disaster victim identification, and special data needs for mobile ID applications.

  • Laser scanner documents crimes scenes quickly, accurately

    See video

    The Carlsbad, California police is using a new laser scanner to capture what happened at crime scene. Thenew technology cuts the time it takes to document a crime scene, from the size of the room to the bullet holes in the wall, by up to 80 percent.

  • Developing educational materials, courses on standards

    So called “documentary standards,” generally developed by industry-based committees, significantly influence industry, commerce and even daily life, but their role is often unrecognized save by those people who are immediately concerned.

  • Using silicon to produce hydrogen on demand

    Super-small particles of silicon react with water to produce hydrogen almost instantaneously, according to researchers. In a series of experiments, the scientists created spherical silicon particles about ten nanometers in diameter. When combined with water, these particles reacted to form silicic acid (a nontoxic byproduct) and hydrogen — a potential source of energy for fuel cells.

  • “Rebound” effect of energy-efficient technology exaggerated

    The argument that those who have fuel-efficient cars drive them more and hence use more energy is overplayed and inaccurate. Researchers find evidence that, indeed, if a technology is cheaper to run – for example, a fuel-efficient car — people may use it more, but the effects of an increased use of the technology are too small to erase energy savings from energy efficiency standards and energy-efficient technologies.

  • Blast-resilient carriages to reduce impact of a terrorist attack on trains, metros

    Engineers have developed a blast-resilient carriages which are better able to withstand a terrorist attack and ultimately save lives. The engineers have e focused on two key areas — containing the impact of the blast and reducing debris — the main cause of death and injury in an explosion and the key obstacle for emergency services trying to gain access to injured passengers.

  • Thwarting facial-recognition, photo-tagging software

    Information about when and where photographed subjects were when their pictures were taken is readily disclosed through photos taken, and the information is disclosed and distributed without their permission. The problem has become even worse due to the popularization of portable terminals with built-in cameras and developments in SNS and image search technologies. Japanese researchers offer a solution: goggles or glasses which, when equipped with near-infrared LED emitter. :

  • New approach to military manufacturing

    In the past, fighter aircraft, tanks, and other complex military systems have been built in a craftsman-like process by a small number of highly specialized contractors. This is a costly approach and DARPA is attempting to replace it with a more efficient “correct by construction” process similar to that practiced by the semiconductor industry, which has an impressive track record in getting systems right in the first place.

  • Metamaterial sensor improves security, collision avoidance

    Engineers have developed a novel sensor which is more efficient, versatile, and cheaper for potential use in such applications as airport security scanners and collision avoidance systems for aircraft, cars, or maritime vessels.

  • Aerial platform helps in developing lightweight sensors for UAVs

    A research team at the Georgia Tech Research Institute (GTRI) is developing an airborne testing capability for sensors, communications devices, and other airborne payloads. This aerial test bed, called the GTRI Airborne Unmanned Sensor System (GAUSS), is based on an unmanned aerial vehicle (UAV) made by Griffon Aerospace and modified by GTRI.

  • New design for clean nuclear fusion reactor unveiled

    Researchers have patented a nuclear fusion reactor by inertial confinement which, in addition to being used to generate electric power in plants, could be applied to propel ships. The fusion chamber shape and size can adapt to the type of fuel being used.

  • Military systems hibernate on the sea floor, then woken up remotely

    Almost half of the world’s oceans are more than four kilometers deep. This provides considerable opportunity for cheap stealth, but the vastness and depth make retrieval costs prohibitive. DARPA wants to developing deployable, unmanned, distributed systems which hibernate on the deep-ocean floor in special containers for years at a time. These deep-sea nodes would then be woken up remotely when needed and recalled to the surface
