A solar-powered airplane finished crossing the United States on Saturday, landing in New York City after flying over the Statue of Liberty during its historic bid to circle the globe, the project team said. The spindly, single-seat experimental aircraft, dubbed Solar Impulse 2, arrived at New York's John F. Kennedy International Airport at about 4 a.m. local time after it took off about five hours beforehand at Lehigh Valley International Airport in Pennsylvania, the team reported on the airplane's website. Such a pleasure to land in New York! For the 14th time we celebrate sustainability," said the project's co-founder Andre Borschberg on Twitter after flying over the city and the Statue of Liberty during the 14th leg of the trip around the globe. The Swiss team flying the aircraft in a campaign to build support for clean energy technologies hopes eventually to complete its circumnavigation in Abu Dhabi, where the journey began in March 2015. The solar cr...
Interestingly a supercomputer situated in the Middle East has entered the main ten rundown of the most intense PCs on the planet. The Shaheen II is based at King Abdullah University of Science and Technology (Kaust) in Saudi Arabia. The Cray XC40 PC is the seventh most intense machine on the planet, said the Top 500 association that screens superior machines. China's Tianhe-2 held its position at the highest point of the supercomputer rundown.
Shaheen II's place on the rundown was uncovered in the Top 500's most recent arrival of its half-yearly rankings. The Shaheen (Peregrine Falcon) II has a crest calculating limit of 5.536 petaflops making it, said the Top 500, "the most astounding positioned Middle East framework in the 22-year history of the rundown and the first to split the Top 10". Kaust has spent about $80m (£51m) purchasing, introducing and working the Cray machine which speaks the truth 25 times more intense than the machine it is supplanting.
The machine utilizes 200,000 processors orchestrated as a part of more than 6,000 hubs, has 17.6 petabytes of capacity and 790 terabytes of fundamental memory. By difference, China's Tianhe-2 has a crest preparing capacity of 33.86 petaflops spread over 16,000 hubs. A petaflop is equivalent to around one quadrillion figurings for every second. One assessment proposes it would take a human around 32,000,000 years to finish the same errand. The machine, situated in Thuwal, Saudi Arabia is being utilized for exploration undertakings demonstrating turbulence in motors, air motion, and renewable vitality networks. Mechanical accomplices of Kaust are additionally wanting to utilize it to help refine their quest for minerals and fossil powers and in the handling of crude materials.
In a web journal passage itemizing the most recent rundown, the Top 500 association said the rate of development in worldwide figuring force was easing off. This was on the grounds that generally couple of new huge supercomputers had been exchanged on in the most recent couple of years. Large portions of those at the highest priority on the rundown were introduced and initially worked in 2011 and 2012, it said
