Radhika Nagpal, expert on swarm robotics, celebrated among ‘Nature’s 10’

first_img Read Full Story Radhika Nagpal, the Harvard computer scientist whose self-organizing swarm robotics are today’s state of the art in collective artificial intelligence, has been named among Nature’s 10, the ten scientists and engineers who “made a difference” in 2014.Nagpal is the Fred Kavli Professor of Computer Science at the Harvard School of Engineering and Applied Sciences (SEAS) and a core faculty member at the Wyss Institute for Biologically Inspired Engineering at Harvard University.In February of this year, her research group announced the creation of a robotic construction crew, inspired by termites, which is capable of assembling blocks into 3-D structures without any human intervention. And in August, Nagpal’s group unveiled its thousand-robot swarm, a massive assembly of small robots that collectively arrange themselves into shapes, interacting much like a school of fish or a flock of birds. Dubbed “the first thousand-robot flash mob,” these Kilobots demonstrate the power of computationally simple programs to collaboratively and autonomously execute complex behaviors.“The beauty of biological systems is that they are elegantly simple — and yet, in large numbers, accomplish the seemingly impossible,” Nagpal said. “At some level you no longer even see the individuals; you just see the collective as an entity to itself.”Nagpal’s research sheds light on the nature of coordination in large groups in order to better understand natural systems like social insect colonies and multicellular self-organization, and to engineer robust and powerful technologies like multi-robot systems for use in search and rescue, construction, or agriculture.last_img read more

Williamson seeks career third Wild West Shootout title

first_imgBy Ben DeatherageEUGENE, Ore. – One of the top contenders to challenge for the fifth annual Wild West Modified Shootout crown is Eugene’s Jesse Williamson.The current Xtreme Motor Sports IMCA Modified campaign has treated him well with four feature wins in only a handful of starts. Two Modified main events have been won in the Modifieds at Cot­tage Grove Speedway while he also has won at the historic 1/4-mile clay oval in a late model.“It has been a good year so far,” said Williamson. “We’ve been fast every time but in a couple of races we’ve broke when contending for the win.”Williamson is the 2012 and 2013 Wild West Modified Shootout champion and is the only driver to repeat a Speedweek crown. Add to his résumé four Cottage Grove Modified Nationals, a Ship­wreck Beads Northwest Modified Nationals crown and last year’s Lon Skinner Memorial victory at Southern Oregon Speedway.He is the all-time leading winner in the history of the Wild West Modified Shootout with six but unfortunately did not manage to win during the 2014 tour. Williamson remains very confident that can return to victory lane during the upcoming Speedweek.“We’ve been working really hard on the car,” he said. “I feel like we are the most prepared we have ever been for a Speedweek.”All seven Speedweek features pay $1,000 to win, a minimum of $100 to start and are Fast Shafts All-Star Invitational ballot qualifying events. Drivers with perfect attendance earn shares of a $3,000 point fund.Teams from Oregon, Washington, California, North Dakota, Montana and British Columbia are expected to make the journey.The tour opens Saturday, June 13 at Southern Oregon Speedway in White City, with following stops Sunday, June 14 at Siskiyou Motor Speedway in Yreka, Calif.; Monday, June 15 at Coos Bay Speedway; Tuesday, June 16 at Cottage Grove Speedway; and Wednesday, June 17 Sunset at Speedway Park in Banks.After a travel day on Thursday, June 18, Speedweek concludes with Friday and Saturday, June 19 and 20 shows at Willamette Speedway in Lebanon.Alex Stanford is the defending tour champion; Brian Poppa topped the inaugural tour standings in 2011.Stanford is second on the Speedweek career wins list with five, followed by Poppa with four, Ken Schrader with two and Mark Carrell, Braedon Hand, Scott Lenz, Travis Peery, Nick Trenchard and Mark Wauge with one eachlast_img read more

Angry Maradona offers reward over ‘death’ report

first_img0Shares0000Diego Maradona was treated by paramedics after he was taken ill after Argentina’s 2-1 win over Nigeria © AFP / Giuseppe CACACEBUENOS AIRES, Argentina, Jun 28 – Diego Maradona has offered a Sh1 million ($10,000) reward to identify the source of reports he had died after Argentina’s World Cup match against Nigeria, his lawyer said Thursday.The reports, circulated via WhatsApp voice messages from a man with an Argentine accent, said the 57-year-old star had been hospitalized and had died of cardiac arrest. “I gave instructions to make public the decision to offer a reward of 300,000 pesos (around $10,000) to anyone who can provide true and accurate information about the author of the audios,” lawyer Matias Morla told Argentina’s Clarin daily from Russia.The Argentine star took ill at the end of the match and had to be helped from his seat.But he denied rumors of ill health the day after, telling reporters: “I’m perfect. I’ve never been better.”Morla said Maradona had suffered “a spike” in blood pressure.“It’s a subject that at one time alarmed him. It’s no secret how he lives through a game. How he lived them as a player is how he lives them as a fan.”According to Morla, Maradona shouldn’t even have been at the stadium for the second half of the game, in which a late goal secured Argentina’s World Cup.“The doctors told him to rest, not to stay for the second half of the Argentina-Nigeria match, but asking that of Maradona is like asking a son not to love his mother.”“For Diego, the team is Dona Tota (his mother), and he will never let her on her own,” he said.The audio messages spread on social media after the match.“Maradona’s sisters heard the news, they could not communicate with me nor with their brother, and one of them suffered a weakness, and the truth is that we cannot let such an outrage go by,” Morla told Clarin.0Shares0000(Visited 1 times, 1 visits today)last_img read more
