Two engineering corrosion researchers from the University of Virginia say public water regulators can avoid disasters like the crisis in Flint, Mich., by adopting predictive models that generate risk assessments based on dynamic data instead of imprecise water sampling. The researchers have demonstrated how chemical thermodynamics can forestall the formation of thermodynamically stable lead-based compounds on lead pipe surfaces.
Instructors at MIT spent the summer finding ways to offer remote classes during the pandemic and safely conduct some instruction in person. Mary Beth Gallagher explores how these classes will be carried out at the school's Department of Mechanical Engineering.
The agriculture industry has been impacted in several different ways over the past few years. Increasing food waste, the labor shortage, and economic instability have created a situation with high risk. Automation is one method farmers can gain some control and create some stability on their own. Test your knowledge and learn how automation will impact the agriculture sector for years to come.
Researchers at the University of Houston have developed a smart electronic skin and a medical robotic hand that could allow physicians to remotely make diagnoses. The system uses a rubbery semiconductor equipped with metallic carbon nanotubes to allow for high carrier mobility.
Researchers from Purdue University are demonstrating how variable valve actuation in diesel engines can reduce fuel consumption and tailpipe emissions. The technology promises to help California meet its strict standards for emissions of carbon dioxide, nitrogen oxide and microscopic particles.
A consortium plans to produce 50 commercially viable, all-composite, modular wheels for electric vehicles by the end of the year. Project partners say the novel system can reduce the weight of a 15-inch wheel by 50% and lead to 5% fuel savings.
Porsche's solution to the challenge of recharging electric vehicles in remote locations is a mobile trailer with charging infrastructure that can handle 10 vehicles at a time. The trailers have been used at numerous events and have provided 5,000 charges, sometimes in extreme temperatures.
More than 1,500 personnel from the US, Australia, Japan and South Korea are joining in the Pacific Vanguard exercise off the coast of Guam. Operations will include combined maneuvers, live fire exercises, anti-submarine warfare and at-sea replenishment.
Software and hardware enhancements were evaluated during four days of UK naval trials of the upgraded Spearfish torpedo in Scotland. The weapon's warhead is described as about six times more potent than the warhead on the smaller Sting Ray torpedo.
Despite challenges amid the coronavirus pandemic, the Navy has had 80% fewer days of maintenance delay in fiscal 2020 than it did in fiscal 2019, said Rear Adm. Eric Ver Hage, commander, Regional Maintenance Center. "In our 2020 DDG [guided-missile destroyer] availabilities, we are tracking to complete 99% of all of our mandatory technical requirements, the things required to keep a ship operating to its full expected life cycle," he said during ASNE's Virtual Fleet Maintenance & Modernization Symposium.
