Jellyfish-inspired soft robots can outswim their natural counterparts

Illustration of a soft robot jellyfish. Credit: NC State University Engineering researchers at North Carolina State University and Temple University have developed soft robots inspired by jellyfish that can outswim their real-life counterparts. More practically, the new jellyfish-bots highlight a technique that uses pre-stressed polymers to make soft robots more powerful. “Our previous work focused on making soft robots that were inspired by cheetahs—and while the robots were very fast, they still had a stiff inner spine,” says Jie Yin,…

This Week in PowerBites: EV Drivetrain MOSFETs, Hybrid Aircraft

>> Electronic Design Resources.. >> Library: Article Series.. .. >> Article Series: PowerBites  4th-Gen SiC MOSFETs Boast Ultra-Low On-Resistance, Target EV Drivetrains With an eye on automotive powertrain applications, ROHM announced its fourth-generation AEC-Q101-qualified, 1200-V silicon-carbide (SiC) MOSFETs. They offer exceptionally low on-resistance that can improve the efficiencies of main drive inverters, as well as power supplies in industrial equipment. As electric vehicles (EVs) and plug-in hybrid EVs (PHEVs) face growing expectations to deliver the range and performance of their…

Innovative grilling technique improves air quality

The team grilled large quantities of skewered meat to measure the emissions. Credit: Fraunhofer IBP Restaurant owners are increasingly turning to fired charcoal grills to prepare meals for customers—but the odors and fumes emitted by these grills are often a source of irritation for nearby residents. The German Environment Agency asked a team of researchers from the Fraunhofer Institute for Building Physics (IBP) to investigate whether the exhaust air treatment systems used in grills actually get the job done and…

Multi-sensor system for the precise and efficient inspection of roads, railways and similar assets

3D laser scanner contained in a housing and mounted on the roof of a vehicle. Credit: Fraunhofer IPM Critical infrastructure such as transport networks are the lifelines of modern society. Extreme weather events may cause damage to railway tracks, roads, tunnels and bridges. The Fraunhofer Institute for Physical Measurement Techniques (IPM) has developed a novel 3-D laser scanner that can be used to closely monitor transport infrastructure and plan maintenance work in a timely manner. The multispectral sensor system measures…

Manufacturing Sets Off Fireworks in June

The International Manufacturing Technology Show is the latest major trade show to close up shop due to the global pandemic. The Association for Manufacturing Technology (AMT), which stages the biannual show in Chicago, said late Monday that the 2020 edition of IMTS has been cancelled after show officials said they could not get assurances from state or city officials that the venue would be cleared to open in time for the September show. “In early May, [Illinois Gov. J.B. Pritzker]…

A closer look at the AI behind course recommendations on LinkedIn Learning, Part 2

Co-authors: Sneha Chaudhari, Mahesh Joshi, and Gungor Polatkan In part 1 of this series, we shared a high-level overview of our course recommendation engine for LinkedIn Learning. First, we provided details on the offline and online components of the system design. Later on, we discussed the three main components of the recommendation engine that are key for generating personalized course recommendations: Response Prediction, Collaborative Filtering, and Blending. We saw that both the Response Prediction and the Collaborative Filtering models play a crucial role…

A Traffic Monitor for Digital Transformation

Artificial intelligence is already turning industries on their heads, and the technology is poised to make an even greater impact on the world in the years to come. Doctors are using AI tools to help with diagnostics, carmakers are working to make autonomous vehicles a widespread reality and nearly all of us each day view online or mobile advertisements that were selected specifically for us by an algorithm. Too often, though, business and IT leaders take a limited view of…
