Project Loon flies for 1 million hours

first_img Project Loon headed to help Puerto Rico Automation software collects wind forecast data, builds maps of where to travel and then processes each balloon’s observation so changes can be made to follow that map. It is this software that directs the balloon’s movements, not the 24/7 team of engineers monitoring them, head of Engineering Salvatore Candido said.According to Candido, the first time he saw a balloon deciding to zig where a human would have chosen to zag, he had to “stare for a while at the strategy the algorithm was trying to execute” before realizing he had been outsmarted by the software.”The first balloon allowed to fully execute this technique set a flight time record from Puerto Rico to Peru,” Candido said. “I had never simultaneously felt smarter and dumber at the same time.”Balloons also choose when to loiter in an area to wait for winds to change, and fly in figure 8 patterns to maintain a constant LTE signal over an area for longer periods.

Project Loon Alphabet’s Project Loon has reached the milestone of flying its balloons in the sky for a collective 1 million hours, the company announced Tuesday. This equates to 40 million kilometers travelled.Project Loon delivers mobile connectivity to remote and disaster-ravaged areas, with the balloons operated by a solar-powered pump. They drift on winds at heights of 50,000 feet to 70,000 feet, tacking like a boat to follow air currents. 0 Project Looncenter_img Alphabet says its Loon balloons could beam internet to more people than before Alphabet’s Loon recruits high-powered mobile veterans to serve on board This Loon internet balloon just spent seven months in the air Share your voice Post a comment 1:16 Mobile Sci-Techlast_img read more

Switching allegiance key to survival in Game of Thrones

first_imgSydney: If you are waiting for the ‘Game of Thrones’ season eight, scheduled to air in April 2019, here are some clues as to which characters are more likely to survive. Evaluating the deaths of all important ‘Game of Thrones’ characters across seven seasons of the show, a team of researchers has found that characters were more likely to survive if they switched allegiances, such as Tyrion Lannister who switches allegiance between the houses Lannister and Targaryen.

The researchers at Macquarie University in Australia also found that the risk of death was also greater for characters that were ‘lowborn’ (not a Lord or Lady), compared to those that were “highborn”. “The risk of death is high among characters in Game of Thrones. By the end of the seventh season, more than half of the characters had died – 186 out of the 330 characters we included in this study – with violent deaths being the most common by far,” said corresponding author of the study.

The most common causes of death were injuries (73.7 per cent), and particularly wounds of the head and neck, including 13 decapitations. Only two deaths from natural causes occurred across the seven seasons of Game Of Thrones: Maester Aemon and Old Nan, who both died of old age. The remainder of deaths were from burns (11.8 per cent) or poisonings (4.8 per cent). The most common circumstances of deaths were assault, operations of war, and legal executions. The probability of dying within the first hour after first appearing on screen was around 14 per cent, the findings showed. The researchers collected data on mortality and survival of 330 characters from all 67 episodes from seasons one to seven of ‘GoT’last_img read more
