  2. Memory leak - Wikipedia

    en.wikipedia.org/wiki/Memory_leak

    To put it another way, a memory leak arises from a particular kind of programming error, and without access to the program code, someone seeing symptoms can only guess that there might be a memory leak. It would be better to use terms such as "constantly increasing memory use" where no such inside knowledge exists.

    The BER is the likelihood of a bit misinterpretation due to electrical noise ().Considering a bipolar NRZ transmission, we have = + for a "1" and () = + for a "0".Each of () and () has a period of .

  5. Superheated steam - Wikipedia

    en.wikipedia.org/wiki/Superheated_steam

    Superheated steam was widely used in main line steam locomotives. Saturated steam has three main disadvantages in a steam engine: it contains small droplets of water which have to be periodically drained from the cylinders; being precisely at the boiling point of water for the boiler pressure in use, it inevitably condenses to some extent in the steam pipes and cylinders outside the boiler ...

  6. Vapor quality - Wikipedia

    en.wikipedia.org/wiki/Vapor_quality

    Steam engines use water vapor to push pistons or turbines, and that movement creates work. The quantitatively described steam quality (steam dryness) is the proportion of saturated steam in a saturated water/steam mixture. In other words, a steam quality of 0 indicates 100% liquid, while a steam quality of 1 (or 100%) indicates 100% steam.

  7. Steam turbine - Wikipedia

    en.wikipedia.org/wiki/Steam_turbine

    An ideal steam turbine is considered to be an isentropic process, or constant entropy process, in which the entropy of the steam entering the turbine is equal to the entropy of the steam leaving the turbine. No steam turbine is truly isentropic, however, with typical isentropic efficiencies ranging from 20 to 90% based on the application of the ...

  9. Wrecking Crew (video game) - Wikipedia

    en.wikipedia.org/wiki/Wrecking_Crew_(video_game)

    The game introduced a new character, a construction foreman named Spike (known as Blackie in the Japanese version), [9] who chases Mario and attempts to disrupt him by knocking down objects and causing him to fall to the bottom of the playfield. The player starts the game with five lives and loses a life whenever Mario comes in contact with an ...
