Thus, the "coverage" product nR nO measures the total observation effort devoted to each video file, with 1.0 corresponding to one observer observing all frames or segments once (or, similarly, two observers each reviewing half the frames).
But Einstein's theory of relativity teaches us that two events cannot be judged to be simultaneous because this judgment depends on the observer's frame of reference.
The energy spectrum model in the wavenumber-frequency domain is constructed in the presence of Doppler shift and broadening as follows: (1) where k and ω denote the streamwise wavenumber and the frequency in the observer's frame (in the Eulerian sense), respectively.
Fifteen out of seventeen observers' first percept with the walker was of CCW rotation; that is, of the walker facing directly away on initial appearance, and the body axis gradually rotating around to face the observer over the subsequent frames (see Figure 1B, lower sequence; slowly cycle through the frames of Movie S1).
For inter-observer agreement to be high, observers must share a frame of reference, sample the same experiences, apply the same standards, and give experiences equal priority.
The software automatically recorded the amount of time required by an observer to analyze each frame.
Einstein located the difficulty in the assumption that absolute space exists; he postulated instead that the laws of nature are the same for observers in any inertial frame of reference and that the speed of light is the same for all such observers.
Afterwards, the tapes were analyzed frame-by-frame by an observer blinded to the randomized treatment assignment of the animalsto determine forelimb usage for contacting the wall of the cylinder during 20 independent rears.
Call one of these observers (and his associated frame of reference) K and the other (and his associated frame of reference) K′.
Yet observers questioned the framing and scope of the Secretary-General's investigation, which sought to determine whether UNAMID had in fact engaged in a cover-up of crimes against civilians and peacekeepers.
