The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; the pattern of position detection was found and determined by applying the least-used ratio (1:1:3:1:1) in black ...
A tool-assisted speedrun or tool-assisted superplay ( TAS; / tæs /) is generally defined as a speedrun or playthrough composed of precise inputs recorded with tools such as video game emulators. Tool-assisted speedruns are generally created with the goal of creating theoretically perfect playthroughs. This includes but is not limited to the ...
The 100-percent APU speed enabled one APU/HPU to supply sufficient operating hydraulic pressure to both servoactuators of that SRB. [citation needed] The APU 100-percent speed corresponded to 72,000 rpm, 110% to 79,200 rpm, and 112% to 80,640 rpm.
The current generates a magnetic field that compresses the plasma. Pinches were the first method for human-made controlled fusion. The z-pinch has inherent instabilities that limit its compression and heating to values too low for practical fusion. The largest such machine, the UK's ZETA, was the last major experiment of the sort. The problems ...
Newman's energy machine. Newman's Energy Machine was a DC motor which the inventor, Joseph Newman, claimed to produce mechanical power exceeding the electrical power being supplied to it. In 1979, Newman attempted to patent the device, but it was rejected by the United States Patent Office as being a perpetual motion machine. [1]
Cruelty-free. In the animal rights movement, cruelty-free is a label for products or activities that do not harm or kill animals anywhere in the world. Products tested on animals or made from animals are not considered cruelty-free, since these tests are often painful and cause the suffering and death of millions of animals every year.
A technetium-99m generator, or colloquially a technetium cow or moly cow, is a device used to extract the metastable isotope 99m Tc of technetium from a decaying sample of molybdenum-99. 99 Mo has a half-life of 66 hours [1] and can be easily transported over long distances to hospitals where its decay product technetium-99m (with a half-life ...
