Anzack suspects caught in Iraq

Fouty were seized May 12 when insurgents attacked and overran a checkpoint near Youssifiyah in a volatile area known as the “triangle of death.” Jimenez and Fouty are still missing. Anzack, a 2005 South High graduate, was also captured during the raid, but his body was found May 23 floating in the Euphrates River. Four U.S. soldiers and an Iraqi soldier were killed during the ambush. The Islamic State of Iraq, a front group for al-Qaida, claimed in an Internet video earlier this year that the missing soldiers were killed and buried. The militants showed images of the military IDs of Jimenez and Fouty but offered no proof that they were dead. “I really hope this leads to information to find our missing boys,” Anzack Sr. added of Jimenez and Fouty. “I would like to be hopeful and for their families to know I’m supporting them and hoping along with them.” U.S. forces also said Thursday that they waged successful battles against both Sunni and Shiite extremists. BAGHDAD – U.S. military forces have seized two suspects linked to the kidnapping of three American soldiers – including Cpl. Joseph Anzack Jr. of Torrance – during a May ambush south of Baghdad. The suspects were captured Monday and Tuesday in Ramadi, the capital of Anbar province, the military announced Thursday. One of the suspects was thought to have “facilitated” the kidnapping and used his house to hide the soldiers, the military said. A weapon belonging to one of the U.S. soldiers was found at the residence of the other suspect. “All I can say is – good,” Anzack’s father, Joseph Anzack Sr., said Thursday on hearing of the arrests. “I’m glad that they got them. I’m still sad my son is gone.” last_img read more

Human pilot beats AI in NASAs drone race

first_imgWashington, Nov 23 (PTI) An expert human pilot was successfully able to beat flying drones controlled by artificial intelligence (AI) systems in a race organised by NASA.However, the AI-driven drones were more consistent in their performance, scientists said.Drone racing is a high-speed sport demanding instinctive reflexes. Researchers at NASAs Jet Propulsion Laboratory (JPL) in the US put their work to the test recently.Timing laps through a twisting obstacle course, they raced drones controlled by AI against world-class drone pilot Ken Loo.The team built three custom drones – dubbed Batman, Joker and Nightwing – and developed the complex algorithms the drones needed to fly at high speeds while avoiding obstacles.The drones were built to racing specifications and could easily go as fast as 129 kilometres per hour in a straight line.However, on the obstacle course set up in a JPL warehouse, they could only fly at 48 to 64 kilometres per hour before they needed to apply the brakes.”We pitted our algorithms against a human, who flies a lot more by feel,” said Rob Reid of JPL, the projects task manager.”You can actually see that the AI flies the drone smoothly around the course, whereas human pilots tend to accelerate aggressively, so their path is jerkier,” Reid said.Compared to Loo, the drones flew more cautiously but consistently. Their algorithms are still a work in progress.For example, the drones sometimes moved so fast that motion blur caused them to lose track of their surroundings.Loo attained higher speeds and was able to perform impressive aerial corkscrews. However, he was limited by exhaustion, something the AI-piloted drones did not have to deal with.advertisement”This is definitely the densest track Ive ever flown. One of my faults as a pilot is I get tired easily. When I get mentally fatigued, I start to get lost, even if Ive flown the course 10 times,” Loo said.While the AI and human pilot started out with similar lap times, after dozens of laps, Loo learned the course and became more creative and nimble.For the official laps, Loo averaged 11.1 seconds, compared to the autonomous drones, which averaged 13.9 seconds. However, the latter was more consistent overall.While Loos times varied more, the AI was able to fly the same racing line every lap.Without a human pilot, autonomous drones typically rely on GPS to find their way around. That is not an option for indoor spaces like warehouses or dense urban areas. A similar challenge is faced by autonomous cars.Camera-based localisation and mapping technologies have various potential applications, Reid added.These technologies might allow drones to check on inventory in warehouses or assist search and rescue operations at disaster sites.They might even be used eventually to help future robots navigate the corridors of a space station.
