• INFRASTRUCTUREAging Bridge Detection Through Digital Image Correlation

    Researchers have developed a novel and practical method of assessing the mechanical properties of structures, with potential application to structural health monitoring of large structures such as bridges and viaducts.

  • NUCLEAR MATTERSUsing Artificial Mussels to Monitor Radioactivity in the Ocean

    Amid the global concern over the pollution of radioactive wastes in the ocean, researchers have conducted a study which has found that “artificial mussels” (AMs) can effectively measure low concentrations of radionuclides in the sea. It is believed that this technology can be applied as a reliable and effective solution for monitoring radioactive contamination around the world.

  • THREAT DETECTIONSoftware System Finds, Tracks Moving Objects as Small as a Pixel

    A new patented software system developed at Sandia can find the curves of motion in streaming video and images from satellites, drones and far-range security cameras and turn them into signals to find and track moving objects as small as one pixel. The developers say this system can enhance the performance of any remote sensing application.

  • TSUNAMI EARLY WARNINGSCreating a Tsunami Early Warning System Using Artificial Intelligence

    Tsunamis are incredibly destructive waves that can destroy coastal infrastructure and cause loss of life. Early warnings for such natural disasters are difficult because the risk of a tsunami is highly dependent on the features of the underwater earthquake that triggers it.

  • EARTHQUKESUsing GSI Sensor Technology to Prediction Earthquakes

    Can nuclear physics improve the prediction of earthquakes? As part of a new project which aims to provide the foundation for a reliable early warning system for earthquakes in Europe, researchers are building a network of sensors measuring radon levels and other parameters in selected water sources in Europe might be able to detect earthquakes several days in advance.

  • AIRPORT SECURITYImproving the Speed and Safety of Airport Security Screening

    By Anne McGovern

    For decades, airports around the nation have employed sensitive canine noses to detect concealed explosives. While this four-legged fleet has been effective and efficient, researchers have yet to build a mechanical method that can mimic their abilities. Researchers seek ways to build non-contact screening methods that can detect concealed explosives at airports.

  • WILDFIRESStoking Wildfire Resilience in Oregon

    Monitoring allows all the moving pieces of an emergency response to launch into action and for decision makers to have as much time as possible to assess and mitigate the threat. This is certainly true when it comes to wildfires. S&T is piloting smoke detection sensors ahead of the 2023 wildfire season.

  • COASTAL CHALLENGESNew Generator Rolls into Ocean Energy

    Tsunamis, hurricanes, and maritime weather are monitored using sensors and other devices on platforms in the ocean to help keep coastal communities safe—until the batteries on these platforms run out of juice. The nanogenerator harnesses the energy of the ocean to power sensors and more.

  • FLOODSLow-Cost Sensor Records the Level of Rivers

    Researchers have developed a method that allows the water level of rivers to be monitored around the clock. The cost-effective sensor is for instance suitable for area-wide flood warning systems.

  • FIRE DETECTIONSensor Technology Detects Fires Before They Start

    Fire alarms generally operate by detecting the presence of smoke, open flame, or higher-than-normal levels of carbon monoxide. Such indicators, however, are byproducts of a fire once it has already started. By using functional nanomaterials-based fire sensor technology, researchers hope to take a step forward from existing detection methods.

  • BRIDGESMobile Data Collected While Traveling Over Bridges Could Help Evaluate Their Integrity

    By Peter Dizikes

    A new study suggests mobile data collected while traveling over bridges could help evaluate their integrity.

  • FLOODSSeismic Sensing Reveals Flood Damage Potential

    Rapidly evolving floods are a major and growing hazard worldwide. Currently, their onset and evolution are hard to identify using existing systems. Seismic sensors already in place to detect earthquakes could be a solution to this problem.

  • VOLCANIC ERUPTIONSNew System Could Provide Early Warning of Whakaari Eruption Risk

    Kiwi volcanologists and engineers have finished testing an automated system that provides a warning when an eruption on Whakaari (White Island) becomes more likely.

  • WILDFIRESNext Generation Wildland Urban Interface (WUI) Alerting Technology

    DHS S&T concluded a proof-of-concept demonstration of the Wildland Urban Interface (WUI) integration model. The model integrates next generation technologies with FEMA’s Integrated Public Alert Warning System (IPAWS) enabling alerting authorities to disseminate Wireless Emergency Alerts (WEAs) with new capabilities.

  • FIRE DETECTIONWi-Fi System Improves Fire Detection

    Engineers have developed a new fire detection system that could help save lives by monitoring the changes in Wi-Fi signals. A Sydney Harbour Tunnel explosion showcases the work of the researchers, which use wireless signals and artificial intelligence to more accurately identify dangerous fire situations.
