    en.wikipedia.org/wiki/Particle_image_velocimetry

    Particle image velocimetry (PIV) is a non-intrusive optical flow measurement technique used to study fluid flow patterns and velocities. PIV has found widespread applications in various fields of science and engineering, including aerodynamics, combustion, oceanography, and biofluids.

    SP 800-73, a NIST special publication, contains the technical specifications to interface with the smart card to retrieve and use the PIV identity credentials. [2] FIPS 201 was replaced by FIPS 201-2 [3] on September 5, 2013, [4] and by FIPS 201-3 in January 2022. [5] Deputy Secretary of the Interior P. Lynn Scarlett demonstrating a PIV card in ...

  4. Seeding (fluid dynamics) - Wikipedia

    en.wikipedia.org/wiki/Seeding_(fluid_dynamics)

    PIV is a technique. In this technique, seed particles are introduced into a fluid. The movement of these particles is captured by high-speed cameras. By analyzing the sequential images, the velocity of the fluid can be determined across the entire field of view. This method is widely used for studying complex flow patterns.

    For example, $225K would be understood to mean $225,000, and $3.6K would be understood to mean $3,600. Multiple K's are not commonly used to represent larger numbers. In other words, it would look odd to use $1.2KK to represent $1,200,000. Ke – Is used as an abbreviation for Cost of Equity (COE).

  9. Peak inverse voltage - Wikipedia

    en.wikipedia.org/wiki/Peak_inverse_voltage

    For rectifier applications, peak inverse voltage (PIV) or peak reverse voltage (PRV) is the maximum value of reverse voltage which occurs at the peak of the input cycle when the diode is reverse-biased. [4] [5] The portion of the sinusoidal waveform which repeats or duplicates itself is known as the cycle. The part of the cycle above the ...
