  2. Sparse Fourier transform - Wikipedia

    en.wikipedia.org/wiki/Sparse_Fourier_transform

    It is one of the top-10 algorithms in the twentieth century. [2] However, with the advent of big data era, the FFT still needs to be improved in order to save more computing power. Recently, the sparse Fourier transform (SFT) has gained a considerable amount of attention, for it performs well on analyzing the long sequence of data with few ...

  3. Power-on hours - Wikipedia

    en.wikipedia.org/wiki/Power-On_Hours

    Power-on hours is intended to indicate a remaining lifetime prediction for hard drives and solid state drives, generally, "the total expected life-time of a hard disk is 5 years" [3] or 43,800 hours of constant use. [4] [5] Typically, after a disk reaches 5 years or 43,800 of power-on time, it is no longer in perfect condition and therefore is ...

  4. CBET-DT - Wikipedia

    en.wikipedia.org/wiki/CBET-DT

    CBET-DT presently broadcasts 5 hours, 50 minutes of locally produced newscasts each week (with 1 hour, 10 minutes each weekday); in regards to the number of hours devoted to news programming, it is the lowest local newscast output among CBC Television's owned-and-operated stations.

  5. Short-time Fourier transform - Wikipedia

    en.wikipedia.org/wiki/Short-time_Fourier_transform

    Simply, in the continuous-time case, the function to be transformed is multiplied by a window function which is nonzero for only a short period of time. The Fourier transform (a one-dimensional function) of the resulting signal is taken, then the window is slid along the time axis until the end resulting in a two-dimensional representation of the signal.

  6. Shut-off nozzle - Wikipedia

    en.wikipedia.org/wiki/Shut-off_nozzle

    Bolt Shut-off Nozzle type BHP - pneumatic or hydraulic actuation. A shut-off bolt, positioned perpendicular to the melt channel moves up and down according to actuation, and thus shuts off/opens the melt flow. This nozzle type has a single melt channel. It therefore does not require rerouting of the melt around the shut-off mechanism.

    US work culture revolves around employees putting in eight hours a day, five days a week — a schedule immortalized by Dolly Parton in her 1980 song “9 to 5.” It’s just the norm, many ...

  8. Process plant shutdown systems - Wikipedia

    en.wikipedia.org/wiki/Process_plant_shutdown_systems

    [2] In a typical depressurization system, the goal is typically reduce the pressure in the plant to less than 50% of the design pressure or to 7 barg, whichever is lower, within 15 minutes. [2] Disposal of blowdown fluids is generally to flare systems or, if safe to do so, non-fired blowdown drums. Blowdown may be strategically delayed by fire ...
