A pulse per second (PPS or 1PPS) is an electrical signal that has a width of less than one second and a sharply rising or abruptly falling edge that accurately repeats once per second. PPS signals are output by radio beacons, frequency standards , other types of precision oscillators and some GPS receivers.
Duckworth–Lewis–Stern method. A rain delay at The Oval, England. Scoreboard at Trent Bridge indicating that bad light has stopped play. The Duckworth–Lewis–Stern method ( DLS) is a mathematical formulation designed to calculate the target score (number of runs needed to win) for the team batting second in a limited overs cricket match ...
A minute of arc is π 10 800 of a radian . A second of arc, arcsecond (arcsec), or arc second, denoted by the symbol ″, [ 2] is 1 60 of an arcminute, 1 3600 of a degree, [ 1] 1 1 296 000 of a turn, and π 648 000 (about 1 206 264.8) of a radian. These units originated in Babylonian astronomy as ...
148×80×15mm. The HP-20S (F1890A) is an algebraic programmable scientific calculator produced by Hewlett-Packard from 1987 to 2000. A member of HP's Pioneer series, the 20S was a low cost model targeted at students, using the same hardware as the HP-10B business calculator. Compared with the higher-end 32S and 42S scientific calculators, the ...
Instructions per second (IPS) is a measure of a computer's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic.
The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 1 2 = 4.9 m. After two seconds it will have fallen 1/2 × 9.8 × 2 2 = 19.6 m; and so on. The next-to-last equation becomes grossly inaccurate at great distances. If an object fell 10 000 m to Earth, then the results of both equations differ ...
The time constant is related to the cutoff frequency fc, an alternative parameter of the RC circuit, by. or, equivalently, where resistance in ohms and capacitance in farads yields the time constant in seconds or the cutoff frequency in Hz. Short conditional equations using the value for : fc in Hz = 159155 / τ in μs. τ in μs = 159155 / fc ...
At the time, Smoot was 5 feet, 7 inches, or 170 cm, tall. [20] Google Earth and Google Calculator include the smoot as a unit of measurement. The Cambridge (Massachusetts) police department adopted the convention of using Smoots to measure the locations of accidents and incidents on the bridge.
