  2. Particle image velocimetry - Wikipedia

    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. The development of PIV can be traced back to the early 20th ...

    en.wikipedia.org/wiki/Pivot_table

    Pivot tables are not created automatically. For example, in Microsoft Excel one must first select the entire data in the original table and then go to the Insert tab and select "Pivot Table" (or "Pivot Chart"). The user then has the option of either inserting the pivot table into an existing sheet or creating a new sheet to house the pivot table.

    An electronic data interchange personal identifier, or EDIPI, is a number assigned to a record in the United States Department of Defense's Defense Enrollment and Eligibility Reporting System (DEERS) database. A record in the DEERS database is a person plus personnel category (e.g. contractor, reservist, civilian, active duty, etc.).

  6. Particle tracking velocimetry - Wikipedia

    en.wikipedia.org/wiki/Particle_tracking_velocimetry

    the three-dimensional particle tracking velocimetry (3-D PTV) is a distinctive experimental technique originally developed to study fully turbulent flows. It is now being used widely in various disciplines, ranging from structural mechanics research to medicine and industrial environments. It is based on a multiple camera-system in a ...

  9. Wind tunnel - Wikipedia

    en.wikipedia.org/wiki/Wind_tunnel

    Particle Image Velocimetry (PIV): PIV is a technique in which a laser sheet is emitted through a slit in the wall of the tunnel where an imaging device is able to track the local velocity direction of particles in the plane of the laser sheet. Sometimes this technique involves seeding the airflow with observable material.
