    [citation needed] The drive does so without any mechanical transmission. [citation needed] Using diaphragms eliminates friction and need for lubricants. [citation needed] When the displacer is in motion, the generator holds the working piston in the limit position, which brings the engine working cycle close to an ideal Stirling cycle.

    A common method is to direct all World Wide Web traffic to a web server, which returns an HTTP redirect to a captive portal. [8] When a modern, Internet-enabled device first connects to a network, it sends out an HTTP request to a detection URL predefined by its vendor and expects an HTTP status code 200 OK or 204 No Content.

  7. Cryptographically secure pseudorandom number generator

    en.wikipedia.org/wiki/Cryptographically_secure...

    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 ...
