SYDNEY Nike AirHuarache Triple Black , Oct. 13 (Xinhua) -- The authorities have evacuated homes and businesses in the Queensland town of Toowoomba while bomb experts investigate a device found outside of a liquor store in the early hours of Tuesday morning.


A Queensland police spokesperson told Xinhua on Tuesday while they cannot confirm what the device is, it is being treated as suspicious with specialist police and the bomb squad currently on the scene.


The authorities were called to the area at 5:20 a.m. local time on Tuesday after a delivery driver reported seeing the device.


The Australian authorities have remained on high alert since 2014 following a spate of terror related incidents in the country, including the shooting of New South Wales police accountant Curtis Cheng by a radicalized 15-year-old boy in early October.

Victoria Azarenka won a showdown between the world's two top players by beating number one Serena Williams in a three set 2-6 6-2 7-6 thriller in the final of the Western and Southern Open on Sunday.


For two hours and 30 minutes, Azarenka and Williams engaged in a seesaw battle before the Belarusian finally clinched the victory, winning a nervy tiebreak 8-6 to prevent the American from ticking a Cincinnati win off her 'bucket list'.


""Obviously, a big win. It was a great match,"" Azarenka told reporters. ""Really, really pleased with the way I pulled it out. It was a great battle.


""There were no giveaways. It was pure fight.""


In a career that has generated 54 singles titles, including 16 grand slams, Williams had won just about everything there is to win in her sport - but not Cincinnati, one of the WTA Tour's most prestigious tournaments.


Cincinnati will remain a hole on her resume for at least another year after Azarenka answered the challenge by claiming just her third win in 15 attempts against the 31-year-old American.


Williams came into the contest with a chance to pass several career milestones beyond a first Cincinnati win but failed to secure any of them.


It was only the second time in 10 finals this season that Williams had failed to walk away with the trophy, while a victory on Sunday would have moved her up a notch on the career wins list into a tie for seventh place with Britain's Virginia Wade and compatriot Lindsay Davenport.


But the day belonged to Azarenka, who bagged her third title of the year and 17th of her career.


""We go against each other really tough, so I think, yeah, it's a good rivalry,"" said Williams. ""I'm number one, she's number two so we have that rivalry which consists of meeting in the final, which makes it even more so exciting.


""I personally was thinking it is a good rivalry and it's good to have someone out there that can play hard and fight so tough.


""She's a great player. There's a reason why she's winning grand slams and doing so well.""


A marquee final featuring the world's number one and two ranked players initially failed to deliver the high-quality spectacle expected from two women who have captured five of the last seven grand slams.


Azarenka, who struggled with her serve against Jelena Jankovic in the semi-finals and held just three times, opened the match with two double faults to hand Williams the early break.


Williams continued her assault on Azarenka with another break at 4-1 that left the Belarusian waving her racket in anger.


""I felt like my energy wasn't maybe there 100 percent at the beginning but that's what the match is about,"" said Azarenka. ""It goes up and down, and you battle against somebody and you have an edge or then you don't have an edge.


""That's what is exciting about that to try to take your opponent to that place where they don't feel at their best.""


In the second set it was Azarenka who had Williams talking to herself as she turned the tables on the muscular American by breaking her three times to level the match.


In the third, Azarenka and Williams finally produced the tennis and edge-of-your-seat drama that fans had come to see, twice trading breaks to send the set into a tiebreak.


With the title on the line, the quality of shots and effort sky-rocketed at both ends of the court before the contest ended with Williams's forehand into the net.

MELBOURNE, March 6 (Xinhua) -- Australian scientists have developed a talking drone that can converse with air traffic controllers as a pilot would, the lead researcher told Xinhua on Friday.


Dr Reece Clothier, leader of the Unmanned Aircraft Systems team at Royal Melbourne Institute of Technology (RMIT), said it was essential drones that were capable of flying safely in civil airspace.


Drones are the fastest growing sector of the aviation industry, with worldwide sales expected to top 6 billion U.S. dollars this year.


He said the communication system his team has designed allowed air traffic controllers to verbally interact with drones which allowed for integration into the current traffic management system. "They sound exactly like a normal pilot," Clothier told Xinhua on Friday. "There will be absolutely no change at all from the air- traffic controller's perspective." "The objective is to make unmanned aircraft appear and interact as seamlessly as possible in the air traffic management system."


On board the unmanned aircraft, radio transmissions are converted into digital messages that the software developed by Clothier's team can interpret. And then, the air traffic controllers can decide on an appropriate instruction or reply.


Clothier said the drones would be able to monitor air traffic control chatter and listen out for their call sign, as pilots currently do.


The next step is imitating the intelligent decision making that pilots undertake in seconds, such as offering alternatives to air traffic control's instructions rather than blindly following.
