  2. Beam propagation method - Wikipedia

    en.wikipedia.org/wiki/Beam_propagation_method

    Beam propagation method. The beam propagation method ( BPM) is an approximation technique for simulating the propagation of light in slowly varying optical waveguides. It is essentially the same as the so-called parabolic equation (PE) method in underwater acoustics. Both BPM and the PE were first introduced in the 1970s.

  3. Speedcore - Wikipedia

    en.wikipedia.org/wiki/Speedcore

    Speedcore. Speedcore is a form of electronic music that is characterized by a high tempo and aggressive themes. [1] It was created in the early to mid-1990s and the name originates from the hardcore genre as well as the high tempo used. Speedcore beats per minute (BPM) is usually classified when a song is around 200+ BPM, but it can vary.

    Lamar released his response song "Meet the Grahams" 20 minutes after the release of "Family Matters".Writing for Complex, Peter Barry characterized the initial response to the track to be positive, stating that "fans rejoiced and took their victory laps, noting the sharp wordplay, the disrespectful easter eggs, and even the spinny G-Unit medallion".

  5. Split-step method - Wikipedia

    en.wikipedia.org/wiki/Split-step_method

    Split-step method. In numerical analysis, the split-step ( Fourier) method is a pseudo-spectral numerical method used to solve nonlinear partial differential equations like the nonlinear Schrödinger equation. The name arises for two reasons. First, the method relies on computing the solution in small steps, and treating the linear and the ...

  6. Fiber-optic splitter - Wikipedia

    en.wikipedia.org/wiki/Fiber-optic_splitter

    A fiber-optic splitter, also known as a beam splitter, is based on a quartz substrate of an integrated waveguide optical power distribution device, similar to a coaxial cable transmission system. The optical network system uses an optical signal coupled to the branch distribution. The fiber optic splitter is one of the most important passive ...

  7. Split-finger fastball - Wikipedia

    en.wikipedia.org/wiki/Split-finger_fastball

    The split-finger fastball is a very effective pitch with runners on base. A common tactic is using the split-finger to cause the batter to hit into a double play. When thrown correctly, the split-finger's apparent last second drop causes many batters to hit the top half of the baseball, thereby inducing a ground ball.

  8. Power dividers and directional couplers - Wikipedia

    en.wikipedia.org/wiki/Power_dividers_and...

    Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit.
