A magnetohydrodynamic generator ( MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity. An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current. The MHD generator uses hot conductive ionized gas (a ...
In the asymptotic setting, a family of deterministic polynomial time computable functions : {,} {,} for some polynomial p, is a pseudorandom number generator (PRNG, or PRG in some references), if it stretches the length of its input (() > for any k), and if its output is computationally indistinguishable from true randomness, i.e. for any probabilistic polynomial time algorithm A, which ...
However, generally they are considerably slower (typically by a factor 2–10) than fast, non-cryptographic random number generators. These include: Stream ciphers. Popular choices are Salsa20 or ChaCha (often with the number of rounds reduced to 8 for speed), ISAAC, HC-128 and RC4. Block ciphers in counter mode.
In mathematics, the root mean square (abbrev. RMS, RMS or rms) of a set of numbers is the square root of the set's mean square. [ 1] Given a set , its RMS is denoted as either or . The RMS is also known as the quadratic mean (denoted ), [ 2][ 3] a special case of the generalized mean. The RMS of a continuous function is denoted and can be ...
An arbitrary waveform generator ( AWG) is a piece of electronic test equipment used to generate electrical waveforms. [1] [2] [3] These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external). The resulting waveforms can be injected into a device under test ...
Hawaii Island Mayor Mitch Roth secured roughly 39% of the votes in Saturday’s primary but fell short of the 50% needed to win outright, likely setting up a runoff in the Nov. 5 general election ...
The Square app is freely downloadable from the Apple App Store and the Google Play Store. Square charges a fee of 2.6% plus $0.10 on every electronically scanned credit card transaction [41] or 3.50% plus $0.15 per manually-entered transaction. No monthly or set-up fees are charged.
A square wave is a non-sinusoidal periodic waveform in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration at minimum and maximum. In an ideal square wave, the transitions between minimum and maximum are instantaneous. The square wave is a special case of a pulse wave which ...
