A clever way to recover weather balloon radiosondes

Credit: Ecole Polytechnique Federale de Lausanne The meteorological sensors carried into the upper atmosphere by weather balloons are often lost as they return to earth. As part of their Bachelor’s project, five EPFL students worked on a system to recover this equipment. Dozens of balloon-borne radiosondes are released into the atmosphere every day. They measure temperature, atmospheric pressure, humidity and wind direction at different altitudes before eventually falling…

Artificial intelligence technology could help protect water supplies

Credit: CC0 Public Domain Progress on new artificial intelligence (AI) technology could make monitoring at water treatment plants cheaper and easier and help safeguard public health. Researchers at the University of Waterloo have developed AI software capable of identifying and quantifying different kinds of cyanobacteria, or blue-green algae, a threat to shut down water systems when it suddenly proliferates. “We need to protect our water supplies,” said Monica Emelko, a professor of civil and environmental engineering and member of…

Solving mystery behind building collapses is latest quest for MU’s Orton

When structures collapse because of an earthquake or another natural disaster, the explanation is easy. When they collapse seemingly out of nowhere, that’s a different story — one that Sarah Orton intends to solve. The goal of Sarah Orton’s latest project is to study structures under high amounts of sustained load and discover why, in the absence of any change in loading or natural disasters, they collapse. Orton, MU associate professor of Civil and Environmental Engineering, and Ying Tian of…

Could studying swarm behaviors teach us how to help drones fly safely?

Credit: Unsplash/James Wainscoat Anyone who’s seen a flock of starlings twist and turn across the sky may have wondered: How do they maneuver in such close formation without colliding? “Many types of animals swarm or flock or otherwise move in coordinated ways,” says Nicholas Ouellette, an associate professor of civil and environmental engineering at Stanford. “No individual animal knows what every other animal is doing, yet somehow they move cohesively as a group.”…

In fact, the Civil and Environmental Engineering major has travelled to more than 35 countries since and racked up an impressive number of…

When study abroad means going home

Cailyn McCarthy will leave for Germany in September and complete her unique study abroad program in February. Photo courtesy of Cailyn McCarthy. For senior Civil and Environmental Engineering student Cailyn McCarthy, spending her final semester studying at the University of Tübingen will be more than a trip abroad. It will be a trip down memory lane. “My family moved to Germany when I was a baby, a little less than two years old,” she said. “We stayed about seven years…

Civil engineers devise a cost-saving solution for cities

Credit: Concordia University Why fix a road today if it’s slated to be ripped up for new sewers next summer? This kind of question is at the heart of research from Tarek Zayed, and Amin Hammad, professors in Concordia’s Department of Building, Civil and Environmental Engineering (BCEE), and PhD candidates Soliman A. Abu-Samra and Mahmoud Ahmed. “Better coordination at city hall is the key to less costly repairs,” says Abu-Samra. “We’ve shown that streamlining maintenance results in huge financial…

New recyclable resin makes wind turbines much more sustainable

The new composite, Elium, cures without added heat and can be recycled when the turbine needs to be replaced. Credit: National Renewable Energy Laboratory and IACMI-The Composites Institute Fields of spinning wind turbines inspire thoughts of earth-friendly energy, but until now, generating wind power hasn’t been as sustainable as people may have thought. It generally requires a great deal of time and energy to cure the type of resin that makes the 150-foot-wide fiberglass turbines strong and durable. When they…
