    en.wikipedia.org/wiki/Hafele–Keating_experiment

    Considering the Hafele–Keating experiment in a frame of reference at rest with respect to the center of the Earth (because this is an inertial frame [3]), a clock aboard the plane moving eastward, in the direction of the Earth's rotation, had a greater velocity (resulting in a relative time loss) than one that remained on the ground, while a ...

  5. Experimental testing of time dilation - Wikipedia

    en.wikipedia.org/wiki/Experimental_testing_of...

    Decay time of muons: The time dilation formula is = , where T 0 is the proper time of a clock comoving with the muon, corresponding with the mean decay time of the muon in its proper frame. As the muon is at rest in S′, we have γ=1 and its proper time T′ 0 is measured.

  6. J-integral - Wikipedia

    en.wikipedia.org/wiki/J-integral

    The J-integral represents a way to calculate the strain energy release rate, or work per unit fracture surface area, in a material. [1] The theoretical concept of J-integral was developed in 1967 by G. P. Cherepanov [2] and independently in 1968 by James R. Rice, [3] who showed that an energetic contour path integral (called J) was independent of the path around a crack.

  7. OBD-II PIDs - Wikipedia

    en.wikipedia.org/wiki/OBD-II_PIDs

    OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.

  9. Timed Up and Go test - Wikipedia

    en.wikipedia.org/wiki/Timed_Up_and_Go_test

    The Timed Up and Go test (TUG) is a simple test used to assess a person's mobility and requires both static and dynamic balance. [ 1 ] It uses the time that a person takes to rise from a chair, walk three meters, turn around 180 degrees, walk back to the chair, and sit down while turning 180 degrees.
