Special Delivery: Machine Learning Tips from Amazon Web Services

Every year, during Amazon’s annual planning process, leaders in every business unit are asked a pointed question: How do you plan to leverage machine learning in your business? The words “we don’t plan to” is not an acceptable answer, said Swami Sivasubramaniam, vice president of Amazon AI at Amazon Web Services.  Speaking from a virtual stage at the Collision from Home conference, Sivasubramaniam told the audience that the world has already entered the golden age of artificial intelligence and machine…

Researchers look for answers as to why western bumblebees are declining — ScienceDaily

A University of Wyoming researcher and her Ph.D. student have spent the last three years studying the decline of the Western bumblebee. The two have been working with a group of bumblebee experts to fill in gaps of missing information from previous data collected in the western United States. Their goal is to provide information on the Western bumblebee to the U.S. Fish and Wildlife Service while it considers listing this species under the U.S. Endangered Species Act. “The decline…

Lagermann Puts Electrical Engineering Courses to Work at Garmin

Isaac Lagermann is putting his electrical engineering courses to work at Garmin this summer. When Isaac Lagermann ’21 began an internship at Garmin earlier this month, he immediately put his electrical engineering courses to work. “As soon as I walked in the door, I was able to contribute and diagnose issues,” Lagermann said. “It’s Mizzou’s teaching that’s helping me out. It’s making me look good.” Lagermann is working at an aircraft hanger just outside the company’s headquarters in Kansas City.…

An international team of astronomers identifies periodic gamma-ray emissions from 11 active galaxies — ScienceDaily

A Clemson University scientist has joined forces with an international team of astronomers to identify periodic gamma-ray emissions from 11 active galaxies, paving the way for future studies of unconventional galaxies that might harbor two supermassive black holes at their centers. Among astronomers, it has long been well-established that most galaxies host a black hole at their center. But galaxies hosting a pair of black holes has remained theoretical. The results of the team’s research appeared in The Astrophysical Journal…

Hubble provides holistic view of stars gone haywire — ScienceDaily

As nuclear fusion engines, most stars live placid lives for hundreds of millions to billions of years. But near the end of their lives they can turn into crazy whirligigs, puffing off shells and jets of hot gas. Astronomers have employed Hubble’s full range of imaging capabilities to dissect such crazy fireworks happening in two nearby young planetary nebulas. NGC 6303 is dubbed the Butterfly Nebula because of its wing-like appearance. In addition, NGC 7027 resembles a jewel bug, an…

This Week in PowerBites: Happier Robots, Surge Busters

Autonomous Wireless Charging for Happier, More Productive Robot Fleets As fleets of robots grow increasingly common throughout the logistic, delivery, and inspection industries, keeping them properly charged has remained a challenge. That’s mostly due to conventional charging systems’ requirements for a physical electrical connection, and some level of human intervention. These bottlenecks have been eliminated by a solution developed by WiBotic, with the assistance of Vicor. WiBotic’s wireless charging solutions facilitate “many-to-many” operation, in which multiple types of robots (even…

Novel vision-based algorithm to track position of spacecraft in real time

Examples of the tracking for the manned spacecraft model. Credit: LIU Chang Guidance, navigation, and control technologies on spacecraft require accurate tracking of the relative six-degree-of-freedom (6-DOF) pose of the spacecraft at close range during space maneuvers such as debris removal, landing, rendezvous and docking. Computer vision techniques have recently become increasingly crucial in 6-DOF pose tracking due to their low energy consumption, rapidness, long work range, and low cost. However, traditional vision-based pose tracking methods suffer from relatively low…

Researchers find new ways to test swarming drones

A UAS outfitted with both a marker strobe (inset) and a traditional survey prism used to evaluate the accuracy of the motion-capture system. Credit: U.S. Army The U.S. Army has implemented a one-of-a-kind outdoor system to test swarming drones—with a capacity of more than 1,500 times the volume of a typical testing facility. Future Soldiers will operate with many of these unmanned aircraft systems across the battlespace, using an interconnected swarm to provide capabilities for situational awareness, defense and logistics.…

Could they have delivered water to the early Earth? — ScienceDaily

The formation of our solar system was a messy affair. Most of the material that existed before its formation — material formed around other, long-dead stars — was vaporized, then recondensed into new materials. But some grains of that material, formed before the sun’s birth, still persist. These “stardust” grains arrived on Earth inside primitive meteorites. New Washington University in St. Louis research led by Nan Liu, an assistant research professor in physics and the Laboratory for Space Sciences in…

Dragon Launch: The Bob and Doug Show

These days everything is drowned out by either COVID-19 or protests. This isn’t to say that either is unimportant, but significant issues are often get overshadowed during such times. One was the launch of SpaceX’s Dragon capsule that was shot up to the International Space Station (ISS) using a Falcon 9 launch vehicle. It’s the first manned launch in years from the U.S.—the astronauts in the capsule were Robert Behnke and Douglas Hurley (Fig. 1). Caption:1. Robert Behnke (left) and…
