WELLINGTON, Sept. 26 (Xinhua) -- New Zealand computer experts said on Monday that they had restored the earliest known recording of computer-generated music, more than 65 years after it was first made.
The two-minute recording, featuring the tunes "God Save the King," "Baa Baa Black Sheep" and the Glenn Miller hit "In the Mood", was made in 1951 in the laboratory of pioneering British computer scientist Alan Turing (1912-1954), said University of Canterbury researchers.
The British Broadcasting Corporation (BBC) used a portable acetate disc cutter to capture the three melodies played by a gigantic "primeval computer" computer filled much of the ground floor of Turing's Computing Machine Laboratory, said Prof. Jack Copeland and composer Jason Long.
"Today all that remains of the recording session is a 12-inch single-sided acetate disc, cut by the BBC's technician while the computer played. The computer itself was scrapped long ago, so the archived recording is our only window on that historic soundscape," Copeland said in a statement.
The pair were disappointed to discover that the frequencies in the recording were not accurate, giving only a rough impression of how the computer sounded.
"But, with some electronic detective work, it proved possible to restore the recording, with the result that the true sound of this ancestral computer can be heard once again, for the first time in more than half a century," he said.
The researchers were able to calculate exactly how much the recording had to be speeded up in order to reproduce the original sound.
"As well as increasing the speed, and so altering the frequencies, we also filtered out extraneous noise from the recording and using pitch-correction software we removed the effects of a troublesome wobble in the speed of the recording," said Copeland.
"It was a beautiful moment when we first heard the true sound of Turing's computer."
HANGZHOU kd 6 all star for sale , Sept. 25 (Xinhua) -- Public ports along China's Grand Canal will all be able to provide shore-side electrical power for docking ships in the next two years.
The Ministry of Transport, National Energy Administration and State Grid Corporation of China on Monday signed an agreement to install shore power facilities along the Grand Canal, which runs over 2 kd trey 5 iii for sale ,500 km from Beijing to Hangzhou.
The facilities will also be installed in ports on the east coast and along the Yangtze River.
Shore power can reduce noise and save diesel a ship burns while it stays at berth.
Emission from ships constitutes a big chunk of global air pollution.
The 130 small shore power facilities installed on three ports along the Grand Canal in Zhejiang Province could cut carbon dioxide emissions by 3,950 tons and reduce fuel consumption by 1,250 tons a year.
The state grid company has more than 600 shore power facilities in ports.

VIENNA kevin durant 7 shoes for sale , Oct. 15 (Xinhua) -- Austria is planning to construct an ornithological observatory to track migratory birds, the Austria Press Agency reported on Wednesday.
The news was announced by the leader of the project Professor Leonida Fusani, an ornithology specialist from the University of Veterinary Medicine in Vienna as well as the University of Vienna.
Fusani said work on the observatory is expected to begin in 2016 kevin durant 6 shoes for sale , when the necessary structures such as databases and servers are set up.
Up to now, the German observatory in Radolfzell in Bodensee has been used to track birds in Austria. Fusani said there have been more and more reasons to have such a facility located in Austria, including an EU request that each member state track bird movements and migrations.
"It has not been the case that up to now ornithologists in Austria have been inactive kevin durant 5 shoes for sale , but now their work can be channelled together," he added.
Gabor Wichmann from Birdlife Austria said the announcement is a "great thing," . Cheap Jerseys Cheap Jerseys Cheap Soccer Hoodies Cheap Hats Cheap NBA Jerseys Cheap MLB Jerseys Cheap Soccer Shirts Cheap NFL Shirts Wholesale NFL Shirts Wholesale NBA Hoodies
